School-based autism evaluations in the COVID-19 era

School psychologists play a critical role in school-based Autism (AU) evaluations. Evidence-based AU evaluations should be multimodal, include multiple informants, and assess functioning across several domains. In the current era of COVID-19, school-based AU evaluations have become increasingly complex with school psychologists having to significantly adapt face-to-face evaluation procedures and/or conduct evaluations via teleassessment approaches. This poses profound challenges for some families, many of whom are from vulnerable groups. In the current article, we outline school psychologists' traditional role in school-based AU evaluations and review best practice guidelines. We then discuss the impact of COVID-19 on these processes and provide a framework for school psychologists to use when conducting school-based AU evaluations during this unprecedented time. We also provide resources school psychologists may find useful as they conduct school-based AU evaluations during the COVID-19 pandemic. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Three gaps and what they may mean for risk preference

Risk preference is one of the most important building blocks of choice theories in the behavioural sciences. In economics, it is often conceptualized as preferences concerning the variance of monetary payoffs, whereas in psychology, risk preference is often thought to capture the propensity to engage in behaviour with the potential for loss or harm. Both concepts are associated with distinct measurement traditions: economics has traditionally relied on behavioural measures, while psychology has often relied on self-reports. We review three important gaps that have emerged from work stemming from these two measurement traditions: first, a description-experience gap which suggests that behavioural measures do not speak with one voice and can give very different views on an individual's appetite for risk; second, a behaviour-self-report gap which suggests that different self-report measures, but not behavioural measures, show a high degree of convergent validity; and, third, a temporal stability gap which suggests that self-reports, but not behavioural measures, show considerable temporal stability across periods of years. Risk preference, when measured through self-reports-but not behavioural tests-appears as a moderately stable psychological trait with both general and domain-specific components. We argue that future work needs to address the gaps that have emerged from the two measurement traditions and test their differential predictive validity for important economic, health and well-being outcomes. This article is part of the theme issue 'Risk taking and impulsive behaviour: fundamental discoveries, theoretical perspectives and clinical implications'.

Measurement of Discrimination of Separation in Elderly Persons Using a Liquid-Crystal Display and Grating Method

This study analyzed psychophysical data from younger and elderly people on the influence of spacing between vertical lines, exposure time, and number of vertical lines in a stimulus for visual performance. A total of 50 elderly people and 31 graduate students participated in the experiment. Nine levels of spacing between lines (3, 6, 9, 12, 15, 18, 21, 24, and 29 points), three exposure times (0.2, 0.6, and 1.0 sec.), and five sets of numbers of lines (4, 5, 6, 7, and 8) were manipulated. Analysis showed enhanced spacing between lines and exposure time improved discrimination of separation. However, although performance on discrimination of separation increased as spacing between lines increased up to 21 points, it was degraded at higher values. A positive effect of number of lines on discrimination of separation was also observed, and performance increased as the number of lines decreased. The effect of age group, i.e., elderly versus younger, on performance was significant. The accuracy of the younger was greater than that for the elderly group. Moreover, three interactive two-way effects were found: group × spacing between lines, number of lines × spacing between lines, and number of lines × exposure time. The present findings could be used as a practical reference in the design of instrument displays in which the operator has to consider the scale and markings on a dial, especially if the display is operated in an emergency or is manipulated by elderly people.

Windows on the human body--in vivo high-field magnetic resonance research and applications in medicine and psychology

Analogous to the evolution of biological sensor-systems, the progress in "medical sensor-systems", i.e., diagnostic procedures, is paradigmatically described. Outstanding highlights of this progress are magnetic resonance imaging (MRI) and spectroscopy (MRS), which enable non-invasive, in vivo acquisition of morphological, functional, and metabolic information from the human body with unsurpassed quality. Recent achievements in high and ultra-high field MR (at 3 and 7 Tesla) are described, and representative research applications in Medicine and Psychology in Austria are discussed. Finally, an overview of current and prospective research in multi-modal imaging, potential clinical applications, as well as current limitations and challenges is given.

Factor structure and psychometrics of the Adolescent Health Risk Behavior survey instrument

OBJECTIVES

To explore the factor structure and psychometric properties of data collected with the Adolescent Health Risk Behavior Survey (AHRBS) instrument.

METHODS

Measures of the AHRBS instrument were tested using statistical analyses to assess validity and reliability of data collected from a sample of 1992 Indiana adolescents.

RESULTS

Factor analyses yielded a 13-factor solution with acceptable model fit statistics. Tests of internal consistency reliability for data in instrument scales ranged from 0.455 to 0.916. Measures were consistent across adolescent subdemographic categories.

CONCLUSION

The AHRBS instrument is a valuable tool for investigating adolescent drug use.

Anxiety provocation and measurement using virtual reality in patients with obsessive-compulsive disorder

The current study is a preliminary test of a virtual reality (VR) anxiety-provoking tool using a sample of participants with obsessive-compulsive disorder (OCD). The tasks were administrated to 33 participants with OCD and 30 healthy control participants. In the VR task, participants navigated through a virtual environment using a joystick and head-mounted display. The virtual environment consisted of three phases: training, distraction, and the main task. After the training and distraction phases, participants were allowed to check (a common OCD behavior) freely, as they would in the real world, and a visual analogy scale of anxiety was recorded during VR. Participants' anxiety in the virtual environment was measured with a validated measure of psychiatric symptoms and functions and analyzed with a VR questionnaire. Results revealed that those with OCD had significantly higher anxiety in the virtual environment than did healthy controls, and the decreased ratio of anxiety in participants with OCD was also higher than that of healthy controls. Moreover, the degree of anxiety of an individual with OCD was positively correlated with a his or her symptom score and immersive tendency score. These results suggest the possibility that VR technology has a value as an anxiety-provoking or treatment tool for OCD.

Development and validation of the child psychosocial distress screener in Burundi

In non-Western countries, efficient and contextually valid methods of community screening are scarce. The present study describes the validation of a new, brief, 7-item multi-informant screener for conflict-affected children (Child Psychosocial Distress Screener; CPDS). To determine concurrent validity, the CPSD was administered to 65 children and their teachers. CPDS scores were compared with indication for psychosocial treatment based on an in-depth clinical assessment by a psychiatrist and psychologist. Construct validity was assessed by testing the measurement equivalence of the CPDS in a community sample (N = 2,240) in Burundi. The CPDS identifies indication for treatment with an accurateness of .81(sensitivity of .84; specificity of .60). Test?retest reliability of the instrument is good (.83). A robust and invariant factor structure provides evidence for the construct validity of the CPSD. The CPDS appears to be a useful multidimensional tool that measures nonspecific child psychosocial distress, detecting children with an indication for treatment. Because of brevity and the ability to be administered by nonspecialists, the CPDS can be an appropriate instrument to screen large populations of conflict-affected children.

Evaluation of an Internet virtual world chat room for adolescent smoking cessation

The goal of this longitudinal study was to test an innovative approach to smoking cessation that might be particularly attractive to adolescent smokers. The study was a participatory research effort between academic and school partners. The intervention used an Internet-based, virtual reality world combined with motivational interviewing conducted in real-time by a smoking cessation counselor. Participants were 136 adolescent smokers recruited from high schools randomized to the intervention or a measurement-only control condition. Those who participated in the program were significantly more likely than controls to report at the immediate post-intervention assessment that they had abstained from smoking during the past week (p<or=.01), smoked fewer days in the past week (p<or=.001), smoked fewer cigarettes in the past week (p<or=.01), and considered themselves a former smoke (p<or=.05). Only the number of times quit was statistically significant at a one-year follow-up assessment (p<or=.05). The lack of longer-term results is discussed, as are methodological challenges in conducting a cluster-randomized smoking cessation study.

CAPAS 2.0: a computer tool for coding transcribed and digitally recorded verbal reports

A new computer software tool for coding and analyzing verbal report data is described. Combining and extending the capabilities of earlier verbal report coding software tools, CAPAS 2.0 enables researchers to code two different types of verbal report data: (1) verbal reports already transcribed and stored in text files and (2) verbal reports in their original digitally recorded audio format. For both types of data, individual verbal report segments are presented in random order and coded independently of other segments in accordance with a localized encoding principle. Once all reports are coded, CAPAS 2.0 converts the coded reports to a formatted file suitable for analysis by statistical packages such as SPSS.

[Multiple visualisation in data analysis: a ViSta application for principal component analysis]

Multiple visualisation (MV) is a statistic graphical method barely applied in data analysis practice, even though it provides interesting features for this purpose. This paper: (1) describes the application of the MV graphical method; (2) presents a number of rules related to the design of an MV; (3) introduces a general outline for developing MVs and shows how MV may be implemented in the ViSta statistical system; (4) illustrates this strategy by means of an example of MV oriented to principal component analysis; and, finally, (5) discusses some limitations of using and developing MVs.

A Computerized Task for Investigating the Relation Between Attentional and Emotional Processes in Children

The authors' goals in this article are to (a) describe a new task for the assessment of shifting attention between different affective stimuli, The Children's Attentional Shifting Task (CAST); (b) present the theoretical background for the development of the CAST; and (c) report initial information on the developmental appropriateness and validity of the CAST. The task was tested using a sample of kindergarten and 1st-grade children, 50% of whom had social and conduct problems. Preliminary analyses showed that the CAST was not subject to problems arising from fatigue or loss of interest. Moreover, children's ability to shift attention away from angry facial expressions was positively related to teachers' ratings of their ability to shift attention and parents' reports of children's emotion regulation. Shifting away from negative affect also predicted children's academic performance as reported by teachers.

Aging, emotion, and health-related decision strategies: motivational manipulations can reduce age differences

According to socioemotional selectivity theory, age-related constraints on time horizons are associated with motivational changes that increasingly favor goals related to emotional well-being. Such changes have implications for emotionally taxing tasks such as making decisions, especially when decisions require consideration of unpleasant information. This study examined age differences in information acquisition and recall in the health care realm. Using computer-based decision scenarios, 60 older and 60 young adults reviewed choice criteria that contained positive, negative, and neutral information about different physicians and health care plans. As predicted, older adults reviewed and recalled a greater proportion of positive than of negative information compared with young adults. Age differences were eliminated when motivational manipulations elicited information-gathering goals or when time perspective was controlled statistically. Implications for improving decision strategies in older adults are discussed.

Computer simulations of the ROUSE model: an analytic simulation technique and a comparison between the error variance-covariance and bootstrap methods for estimating parameter confidence

This article provides important mathematical descriptions and computer algorithms in relation to the responding optimally with unknown sources of evidence (ROUSE) model of Huber, Shiffrin, Lyle, and Ruys (2001), which has been applied to short-term priming phenomena. In the first section, techniques for obtaining parameter confidence intervals and parameter correlations are described, which are generally applicable to any mathematical model. In the second section, a technique for producing analytic ROUSE predictions is described. Huber et al. (2001) averaged many stochastic trials to obtain stable behavior. By appropriately weighting all possible combinations of feature states, an alternative analytic version is developed, yielding asymptotic model behavior with fewer computations. The third section ties together these separate techniques, obtaining parameter confidence and correlations for the analytic version of the ROUSE model. In doing so, previously unreported behaviors of the model are revealed. In particular, complications due to local minima are discussed, in terms of both variance-covariance analyses and bootstrap sampling analyses.

Characteristics of body excursion during a static upright posture in elderly people with central nervous system disorders and with other disorders from the viewpoint of body-excursion parameters

This study aimed to compare characteristics of body excursion of healthy elderly and elderly people with disorders. The participants were 38 healthy elderly who were at home (Healthy Elderly group) and 24 elderly people with disorders. The latter consisted of two groups: 12 in the Central Nervous System Disorders group with vestibular organ or central nervous system disorders, and 12 in the Other Disorders group with other system disorders. 34 parameters were selected from six domains: distance, distribution of amplitude, area, velocity, power spectrum, and vector. When compared with the Healthy Elderly group, the Central Nervous System Disorders group was judged abnormal on many parameters and showed large and quick body excursion characteristics, particularly in left-right excursion. The Other Disorders group showed different characteristics in the size of the left-right excursion and velocity of the front-back excursion. However, compared with the Central Nervous System Disorders group, very few people in the Other Disorders group were judged abnormal, and they showed slower velocity for front-back excursion.

Assessing dissimilarity relations under missing data conditions: Evidence from computer simulations

The extensive research examining relations between group member dissimilarity and outcome measures has yielded inconsistent results. In the present research, the authors used computer simulations to examine the impact that a methodological feature of such research, participant nonresponse, can have on dissimilarity-outcome relations. Results suggest that using only survey responders to calculate dissimilarity typically results in underestimation of true dissimilarity effects and that these effects can occur even when response rates are high.

Detecting eye movements in dynamic environments

To take advantage of the increasing number of in-vehicle devices, automobile drivers must divide their attention between primary (driving) and secondary (operating in-vehicle device) tasks. In dynamic environments such as driving, however, it is not easy to identify and quantify how a driver focuses on the various tasks he/she is simultaneously engaged in, including the distracting tasks. Measures derived from the driver's scan path have been used as correlates of driver attention. This article presents a methodology for analyzing eye positions, which are discrete samples of a subject's scan path, in order to categorize driver eye movements. Previous methods of analyzing eye positions recorded in a dynamic environment have relied completely on the manual identification of the focus of visual attention from a point of regard superimposed on a video of a recorded scene, failing to utilize information regarding movement structure in the raw recorded eye positions. Although effective, these methods are too time consuming to be easily used when the large data sets that would be required to identify subtle differences between drivers, under different road conditions, and with different levels of distraction are processed. The aim of the methods presented in this article are to extend the degree of automation in the processing of eye movement data by proposing a methodology for eye movement analysis that extends automated fixation identification to include smooth and saccadic movements. By identifying eye movements in the recorded eye positions, a method of reducing the analysis of scene video to a finite search space is presented. The implementation of a software tool for the eye movement analysis is described, including an example from an on-road test-driving sample.

RUI: Recording user input from interfaces under Windows and Mac OS X

Event and timing logs are useful i n studying human-computer interaction,evaluating applications, and comparing input devices. Recording User Input (RUI) is a tool that records user-computer interface behavior. It is created in the .Net framework with C# for Windows and in the Carbon framework for Mac OS X. RUI runs in the background and works with software that runs under Windows or Mac OS X (10.3 Panther and later versions). We illustrate its use with a human-robot interaction interface and present two simple tests that RUI passes and that other timing software should pass: avoiding 0-msec timings and time distributions that follow a gamma (or gamma-like) distribution.

Cognitive technologies for gist processing

Cognitive technologies extend our cognitive abilities, yet they are currently deficient in many respects. According to fuzzy-trace theory, people are gist processors with a fuzzy-processing preference, and information is mentally represented along a fuzzy-to-verbatim continuum. An understanding of gist processing could form the basis of a new generation of more effective cognitive technologies. This suggests, first, the need for new tools to help Web page creators optimize gist representations of text. Such a system could provide feedback about the visitor's gist and make recommendations about rewriting. It also suggests the need for new tools to help authors create more effective means of presenting quantitative data in visual form. The advocated approach capitalizes on the collective knowledge of communities of practice on the Web. Finally, it suggests the need for new tools for collecting input from users. The facial composite system EvoFIT is cited as an example.

SCiP at 35: An idiosyncratic history of the Society for Computers in Psychology

SCiP history may be divided into three eras: the Paleozoic (1971-1982), the Mesozoic (1982-1994), and the Cenozoic (1994-present). Following a list of Secretary-Treasurers, a list of all SCiP Presidents is provided in Table 1. Next I present personal highlights, including the first symposium on psychology and the World-Wide Web; David Rumelhart's mathematical explanation of connectionism; and Stevan Hamad's discussion of "freeing" the journal literature. I observe that a small conference is becoming more intimate and that much of our mission involves figuring out how to conduct high-quality scientific research with consumer-grade electronics. I argue that we are an increasingly international organization, that graduate students are welcome, and that we should become more inclusive in the areas of gender and ethnicity and should make membership more meaningful I conclude by looking ahead and attempting to predict the future.

Pocket-sized psychology studies: Exploring daily diary software for Palm Pilots

Daily dairies, also known as experience sampling methods (ESM) or everyday experience methods, are a common methodology utilized to provide insight into momentary psychological processes. Traditionally, such studies often have utilized paper-and-pencil surveys administered several times each day over a span of several days or weeks. However, advances in technology now allow these studies to be conducted using palmtop computers (i.e., personal digital assistants; PDAs). Three software packages for running these studies on the Palm operating system were explored and compared on a number of features Specifically, ESP (Experience Sampling Program, by Feldman Barrett & Barrett, 2001), iESP Version 3.2 (Intel Experience Sampling Program, by Intel Research Seattle & the University of Washington Computer Science and Engineering Department), and PMAT Version 2.0 (Purdue Momentary Assessment Tool, by the Military Family Research Institute at Purdue University) were examined, with their key features compared. These advances in software for running diary studies include a number of features that provide researchers with methods and information previously unavailable in diary studies and may expand the range of possibilities in diary study designs.

A time for specificity

McGrath's (2005/this issue) article, "Conceptual Complexity and Construct Validity," is a happy sign that the serious reform necessary for theoretical progress in the study of human personality and psychopathology may be entering a formative phase.

What does it mean that an issue is conceptual in nature?

McGrath (2005/this issue) argues that "the conceptual complexity [italics added] of the constructs psychologists choose to measure and the scales they use to measure them has played an important role in the failure to develop more accurate measurement systems" (p. 112). Although we agree with this, we argue, in this commentary, that McGrath has misdiagnosed the source of these difficulties and that this misdiagnosis originates with an unresolved articulation of the nature of a conceptual issue and of the relationship between conceptual and empirical issues in science.

Conceptual complexity and construct validity

Despite a century of methodological and conceptual advances in the technology of psychosocial measurement, poor correspondence between indicators and the constructs they are intended to represent remains a limiting factor to the accumulation of scientific knowledge. Longstanding conventions in measurement may contribute to the failure to develop optimal criteria. These conventions include the focus on complex over simple constructs and the use of multi-item measures of disparate content to represent those constructs. Several arguments suggest that such a measurement model compromises the potential for developing measures that accurately reflect psychosocial phenomena. The article concludes with some preliminary suggestions concerning an alternative model that may address this construct validity problem more effectively.

Psychology Experiment Authoring Kit (PEAK): formal usability testing of an easy-to-use method for creating computerized experiments

In academic courses in which one task for the students is to understand empirical methodology and the nature of scientific inquiry, the ability of students to create and implement their own experiments allows them to take intellectual ownership of, and greatly facilitates, the learning process. The Psychology Experiment Authoring Kit (PEAK) is a novel spreadsheet-based interface allowing students and researchers with rudimentary spreadsheet skills to create cognitive and cognitive neuroscience experiments in minutes. Students fill in a spreadsheet listing of independent variables and stimuli, insert columns that represent experimental objects such as slides (presenting text, pictures, and sounds) and feedback displays to create complete experiments, all within a single spreadsheet. The application then executes experiments with centisecond precision. Formal usability testing was done in two stages: (1) detailed coding of 10 individual subjects in one-on-one experimenter/subject videotaped sessions and (2) classroom testing of 64 undergraduates. In both individual and classroom testing, the students learned to effectively use PEAK within 2 h, and were able to create a lexical decision experiment in under 10 min. Findings from the individual testing in Stage 1 resulted in significant changes to documentation and training materials and identification of bugs to be corrected. Stage 2 testing identified additional bugs to be corrected and new features to be considered to facilitate student understanding of the experiment model. Such testing will improve the approach with each semester. The students were typically able to create their own projects in 2 h.

Incremental Validity of a Measure of Emotional Intelligence

After the Schutte Self-Report Inventory of Emotional Intelligence (SSRI; Schutte et al., 1998) was found to predict college grade point average, subsequent emotional intelligence (EI)-college adjustment research has used inconsistent measures and widely varying criteria, resulting in confusion about the construct's predictive validity. In this study, we assessed the SSRI's incremental validity for a wide range of adjustment criteria, pitting it against a competing trait measure, the NEO Five-Factor Inventory (NEO-FFI; Costa & McCrae, 1992), and tests of fluid and crystallized intelligence. At a broad bandwidth, the SSRI total score significantly and uniquely predicted variance beyond NEO-FFI domain scores in the UCLA Loneliness Scale, Revised (Russell, Peplau, & Cutrono, 1980) scores. Higher fidelity analyses using previously identified SSRI factors and NEO-FFI item clusters revealed that the SSRI's Optimism/Mood Regulation and Emotion Appraisal factors contributed unique variance to self-reported study habits and social stress, respectively. The potential moderation of incremental validity by gender did not reach significance due to loss of power from splitting the sample, and mediational analyses revealed the SSRI Optimism/Mood Regulation factor was both directly and indirectly related to various criteria. We discuss the small magnitude of incremental validity coefficients and the differential incremental validity of SSRI factor and total scores.

PsychMate: Providing psychology majors the tools to do real experiments and learn empirical methods

PsychMate is a set of software tools for undergraduate psychology students to run, develop, and analyze computerized experiments. It includes 30 psychological experiments in the areas of perception, cognition, social psychology, human factors, and cognitive neuroscience. Students run experiments themselves and see basic results immediately. The automatic spreadsheet analysis forms allow them to aggregate data and create analyses, presentations, and Web pages with a single click. Students can use the Psychology Experiment Authoring Kit experiment editor to create their own experiments in minutes and run experiments with other students using Web-based experiment-management tools. The BrainTutor and BrainViewer applications teach brain anatomy and permit students to analyze fMRI brain imaging data from subjects who have performed the same memory experiments in which they participated. PsychMate has been used in 83 classes in which 1,533 students submitted 5,464 completed experiments with few (less than 1%) requests for help and a very positive rating of the research experience.

Computing aspects of power for multiple regression

Rules of thumb for power in multiple regression research abound. Most such rules dictate the necessary sample size, but they are based only upon the number of predictor variables, usually ignoring other critical factors necessary to compute power accurately. Other guides to power in multiple regression typically use approximate rather than precise equations for the underlying distribution; entail complex preparatory computations; require interpolation with tabular presentation formats; run only under software such as Mathmatica or SAS that may not be immediately available to the user; or are sold to the user as parts of power computation packages. In contrast, the program we offer herein is immediately downloadable at no charge, runs under Windows, is interactive, self-explanatory, flexible to fit the user's own regression problems, and is as accurate as single precision computation ordinarily permits.

Roles of instruments in psychological research

What roles have instruments played in psychology and related disciplines? How have instruments affected the dynamics of psychological research, with what possibilities and limits? What is the psychological instrument? This article provides a conceptual foundation for specific case studies concerning such questions. The discussion begins by challenging widely accepted assumptions about the subject and analyzing the general relations between scientific experimentation and the uses of instruments in psychology. Building on this analysis, a deliberately inclusive definition of what constitutes a psychological instrument is proposed. The discussion then takes up the relation between instrumentation and theories and differentiates in greater detail the roles instruments have had over the course of psychology's history. Finally, the authors offer an approach to evaluating the possibilities and limitations of instruments in psychology.

[The stimulated recall method: a research tool applicable to learning at science museums]

The article reports on preliminary research aimed at developing a methological tool applicable to studies of learning in informal educational settings. The study was conducted at two science museums, using a modified version of the stimulated recall method. Digital photographs replaced the traditional video in the final phase, during which eight interviews were conducted, with satisfactory results. The digital photos efficaciously and efficiently stimulated visitors to narrate their experiences and to convey the meanings they took with them from their interactions with the exhibits.

Effects of outside issues on the comparison question test

In the present study, the authors examined the effects of outside issues on the validity of the Comparison Question Test in a laboratory mock-crime paradigm. In a 2 x 2 x 2 factorial design, 192 participants either did or did not commit (a) a mock theft of a dollar (about which they were tested), or (b) a mock theft of dollars 20 (the outside issue); and they either were or were not asked questions about an outside issue. The presence of the outside issue had a strong differential impact on the participants who were innocent of the tested issue, and it dramatically moved their scores toward deception. The impact of an outside issue on the guilty was minimal. Test questions about possible outside issues were ineffective in detecting the presence of the outside issue, but they did function as comparison questions. The results have implications for understanding the high rate of false positive outcomes in some studies.

Psychology over the Internet: On-Line Experiences

The "International Symposium on Psychology over the Internet: On-Line Experiences" was held in Lima, Peru, July 2003, at the 29th InterAmerican Congress of Psychology. The main topic was the advantages and disadvantages of using this technology in the applied field of psychology. The Internet has been considered a new alternative for teaching-learning processes (virtual classroom); vocational assessment; counseling and orientation (virtual psychological consultation); and intervention focused on specific health-related problems. These experiences of on-line psychological services and their conclusions are briefly described herein.

B.F. Skinner and the auditory inkblot: The rise and fall of the verbal summator as a projective technique

Behaviorist B.F. Skinner is not typically associated with the fields of personality assessment or projective testing. However, early in his career Skinner developed an instrument he named the verbal summator, which, at one point, he referred to as a device for "snaring out complexes," much like an auditory analogue of the Rorschach inkblots. Skinner's interest in the projective potential of his technique was relatively short lived, but whereas he used the verbal summator to generate experimental data for his theory of verbal behavior, several other clinicians and researchers exploited this potential and adapted the verbal summator technique for both research and applied purposes. The idea of an auditory inkblot struck many as a useful innovation, and the verbal summator spawned the tautophone test, the auditory apperception test, and the Azzageddi test, among others. This article traces the origin, development, and eventual demise of the verbal summator as an auditory projective technique.

New Diagnostic Tool for Robotic Psychology and Robotherapy Studies

Robotic psychology and robotherapy as a new research area employs a systematic approach in studying psycho-physiological, psychological, and social aspects of person-robot communication. An analysis of the mechanisms underlying different forms of computer-mediated behavior requires both an adequate methodology and research tools. In the proposed article we discuss the concept, basic principles, structure, and contents of the newly designed Person-Robot Complex Interactive Scale (PRCIS), proposed for the purpose of investigating psychological specifics and therapeutic potentials of multilevel person-robot interactions. Assuming that human-robot communication has symbolic meaning, each interactive pattern evaluated via the newly developed scale is assigned certain psychological value associated with the person's past life experiences, likes and dislikes, emotional, cognitive, and behavioral traits or states. PRCIS includes (1) assessment of a person's individual style of communication with the robotic creature based on direct observations; (2) the participant's evaluation of his/her new experiences with an interactive robot and evaluation of its features, advantages and disadvantages, as well as past experiences with modern technology; and (3) the instructor's overall evaluation of the session.

A computer-aided digital audio recording and encoding system for improving the encoding of verbal reports

The increasing use of verbal reports in psychological research requires tools for improving the ease and reliability of collecting and coding verbal report data. An approach is described that maintains the verbal report data in digitally recorded audio form throughout the collecting and encoding processes. A new computer-aided encoding tool, CAPAS, is described, which randomly selects and plays individual protocol segments and stores computer keyboard-entered codes in an SPSS-formatted data file.

The use of the internet in psychological research: comparison of online and offline questionnaires

The Internet can be an effective medium for the posting, exchange, and collection of information in psychology-related research and data. The relative ease and inexpensiveness of creating and maintaining Web-based applications, associated with the simplicity of use via the graphic-user interface format of form-based surveys, can establish a new research frontier for the social and behavioral sciences. To explore the possible use of Internet tools in psychological research, this study compared Web-based assessment techniques with traditional paper-based methods of different measures of Internet attitudes and behaviors in an Italian sample. The collected data were analyzed to identify both differences between the two samples and in the psychometric characteristics of the questionnaires. Even if we found significant differences between the two samples in the Internet attitudes and behaviors, no relevant differences were found in the psychometric properties of the different questionnaires. This result, similar to the ones previously obtained in Web-based assessments of personality constructs, is even more interesting given the lack of control on the characteristics of the online sample. These finding suggests that, if sampling control and validity assessment is provided, Internet-based questionnaires can be a suitable alternative to more traditional paper-based measures.

Measuring psychomotor agitation by use of an actimeter: a pilot study

BACKGROUND

Psychomotor agitation is variably defined, with differing emphases on subjective and motor components. We assess the utility of an actimeter to inform us about aspects of the motor component.

METHODS

A wrist actimeter measured motor activity of three inpatients with agitated depression.

RESULTS

For each patient, diurnal activity patterns were observed, with activity generally elevated in mornings and late afternoons. Each patient also evidenced a clear decline in motor activity in the mid-evening, with little or no activity recorded during 'sleep' hours. Thus, psychomotor agitation (like motor activity) appears to require a conscious state.

LIMITATIONS

Actimeters measure any baseline activity together with any superimposed movement component (which may range from movement changes to medication effects), making it difficult to disentangle components. We studied few patients and for brief intervals.

The effect of situation-evoked anxiety and gender on pain report using the cold pressor test

The aims of the present study were to investigate the influence of anxiety on pain perception and to test whether gender differences in pain perception are anxiety dependent. Sixty male and female university students exposed to situation-evoked anxiety or a control procedure were measured for their pain threshold, tolerance, and perceived intensity during a cold pressor test. Both subjective and autonomic responses indicated that anxiety was successfully induced in participants exposed to the anxiety condition. Increased situational anxiety had no significant effect on pain threshold or pain tolerance. Significant increases in pain intensity were found for the anxiety group. Levels of anxiety, however, did not correlate with this increased intensity, raising doubt as to the role of anxiety in producing this effect. No gender differences were found for pain tolerance or pain intensity. Gender differences were found for pain threshold in the anxiety group with, contrary to past findings, females showing significantly higher pain thresholds than males. The results are discussed in the light of related studies.

Computer technology applications in industrial and organizational psychology

This article reviews computer applications developed and utilized by industrial-organizational (I-O) psychologists, both in practice and in research. A primary emphasis is on applications developed for Internet usage, because this "network of networks" changes the way I-O psychologists work. The review focuses on traditional and emerging topics in I-O psychology. The first topic involves information technology applications in measurement, defined broadly across levels of analysis (persons, groups, organizations) and domains (abilities, personality, attitudes). Discussion then focuses on individual learning at work, both in formal training and in coping with continual automation of work. A section on job analysis follows, illustrating the role of computers and the Internet in studying jobs. Shifting focus to the group level of analysis, we briefly review how information technology is being used to understand and support cooperative work. Finally, special emphasis is given to the emerging "third discipline" in I-O psychology research-computational modeling of behavioral events in organizations. Throughout this review, themes of innovation and dissemination underlie a continuum between research and practice. The review concludes by setting a framework for I-O psychology in a computerized and networked world.

The first memory drum

For most of the 20th century, the memory drum was the standard American apparatus for memory research. The first memory drum dates from 1887 in the work of G. E. Müller and Frederich Schumann, and an illustration of their device appeared 16 years later. This device apparently was invented to resolve the difficulties created by Ebbinghaus's method. The memory drum was a kymograph used to control the display of learning materials. Cattell used something similar for his dissertation with Wundt, though not for verbal material. From Müller's writings, images of this device and kymographs contemporary to Müller's innovation, characteristics, aspects, and difficulties of the development of this drum are presented in the context of its use to resolve the difficulties created by Ebbinghaus's method. An improved device was offered by instrument makers Diederichs in Göttingen and Zimmermann in Leipzig, both in 1894. Surprisingly, from 1903 Zimmermann offered only the original, unimproved device, mistakenly portraying it as appropriate for paired-associate learning procedures.

No-suicide contracts: an overview and recommendations

No-suicide contracts, in their various forms, can deepen commitment to a positive action, strengthen the therapeutic alliance, facilitate communication, lower anxiety, aid assessment, and document precautions. Conversely, they can anger or inhibit the client, introduce coercion into therapy, be used disingenuously, and induce false security in the clinician. Research on no-suicide contracts (frequency surveys, assessments of behavior after contracting, and opinions of users) has limitations common to naturalistic studies, and is now ready for more rigorous methods. Mental health professions should be trained to deal with suicidal individuals, including how to use no-suicide contracts. Good contracts are specific, individualized, collaborative, positive, context-sensitive, and copied. However, they are not a thorough assessment, a guarantee against legal liability, nor a substitute for a caring, sensitive therapeutic interaction. No-suicide contracts are no substitute for sound clinical judgment.

[Cognitive impairment and cardiovascular disease risk factors. Project CASCADE Kraków. II. Agreement of Mini-Mental State Examination (MMSE) obtained by nurses and by psychologists from the same persons at age 67-78 years of age]

Mini-Mental State Examination (MMSE) can be used for screening procedures by personnel with no university training in psychology. However, little is known on the reliability of the results of MMSE obtained by medical personnel with little experience in cognitive function assessment. The goal of the paper was to assess the agreement between the results of MMSE obtained by trained community nurses and by psychologists, and to study whether the agreement depends on age, sex and education of examined persons. Studied group were 92 women and 90 men at age 65-78 years. Most of them (81.3%) had only elementary education. There was no significant difference between the distribution of the results obtained by nurses and obtained by psychologists. Individual difference < or = 2 points was found in 63.1% participants and difference < or = 3 points in 78.4% participants. There was a significant correlation between the results obtained by nurses and by psychologists (r = 0.64, p < 0.001). The correlation was also significant within the age, sex and education strata. Variation of the results obtained by nurses was explained in 42% by variation of the results obtained by psychologists. The best agreement in classification in cognitive function was found for the MMSE cut-off point < or = 19 (kappa = 0.75 in women and kappa = 0.58 in men). The worst agreement was found for the cut-off point < or = 25. Also weak agreement was found for the cut-off point < or = 23. There was a significant agreement between the results of MMSE obtained by nurses and results obtained by psychologists on the population level. However at the level of individuals the agreement in classification of cognitive function depended of cut-off point used. The agreement was only fair if cut-off point < or = 23 and < or = 25 were used.

Modular neural networks: a survey

Modular Neural Networks (MNNs) is a rapidly growing field in artificial Neural Networks (NNs) research. This paper surveys the different motivations for creating MNNs: biological, psychological, hardware, and computational. Then, the general stages of MNN design are outlined and surveyed as well, viz., task decomposition techniques, learning schemes and multi-module decision-making strategies. Advantages and disadvantages of the surveyed methods are pointed out, and an assessment with respect to practical potential is provided. Finally, some general recommendations for future designs are presented.

Evaluation of the elevated T-maze as an animal model of anxiety in the mouse

The elevated T-maze has been developed as an animal model of anxiety to generate both conditioned and unconditioned fears in the same rat. This study explores a version of the elevated T-maze fit for mice. Inhibitory (passive) avoidance- conditioned fear-is measured by recording the latency to leave the enclosed arm during three consecutive trials. One-way escape- unconditioned fear-is measured by recording the time to withdraw from open arms. The results showed that mice do not appear to acquire inhibitory avoidance in the standard T-maze, since their latencies to leave enclosed arm did not increase along trials. Nevertheless, the open arms seemed to be aversive for mice, because the latency to leave the enclosed arm after the first trial was lower in a T-maze with the three enclosed arms than in the standard elevated T-maze. In agreement, the exposure of mice to an elevated T-maze without shield, that reduces the perception of openness, increased significantly the latencies to leave the enclosed arm. However, the absence of the shield also increased the time taken to leave the open arms when compared to that recorded in standard T-maze. Systematic observation of behavioral items in the enclosed arm has shown that risk assessment behavior decreases along trials while freezing increases. In the open arms, freezing did not appear to influence the high latency to leave this compartment, since mice spend only about 8% of their time exhibiting this behavior. These results suggest that mice acquire inhibitory avoidance of the open arms by decreasing and increasing time in risk assessment and freezing, respectively, along three consecutive trials. However, one-way escape could not be characterized. Therefore, there are important differences between mice (present results) and rats (previously reported results) in the performance of behavioral tasks in the elevated T-maze.

Hardware and software for tachistoscopy: how to make accurate measurements on any PC utilizing the Microsoft Windows operating system

Methods for automated stimulus display and accurate response time measurement with IBM-compatible PCs are of great importance in cognitive research designs. Accurate measurements of reaction times are required to interpolate other measures, such as speed of mental processing. We present a description of hardware and software that displays stimulus images and performs reaction timing that is not dependent on PC performance characteristics. This is accomplished by electronically bypassing timing errors normally inherent to the operation of the computer. A high-precision external timer measures the time between stimulus onset and a subject's push-button response while a video blanking circuit controls the video presented to the monitor screen. Two options for accurately detecting stimulus onset are presented: (1) A photodetector can be used to sense the actual onset of the stimulus on a secondary video monitor screen; (2) the video blanking circuit can provide a signal coincident with the initiation of video to the monitor. Both methods result in a system timing accuracy of 100 microseconds.

A rotating holeboard procedure for testing drug effects on spatial learning and memory in mice

A procedure is described herein for evaluating drug effects on acquisition and retention of a spatial learning task in mice. The rotating holeboard apparatus is a rectangular open field containing four open holes arranged in either a four-corner or a row configuration. A mouse is trained to poke its head into a hole and retrieve a food reward from a 'baited' hole which contains a reward on every trial. A massed trials protocol is used where mice are required to learn a reference (trial-independent) memory task in a single session. A retention test is administered 24 h after acquisition. Prominent distal cues are present in the testing room and reliance on proximal visual, olfactory, or tactile cues for locating the baited hole is precluded by rotating the maze on each trial.
