Schizotypal traits and anomalous perceptual experiences are associated with greater visual temporal acuity

One of the main tasks of the human visual system is to organize the temporal flow of visual events into meaningful patterns. It has been suggested that segregation/integration of continuous visual stimuli relies on temporal windows that are phase-locked to brain oscillations in the alpha frequency range (~10 Hz). From a behavioral point of view, the balance between integration and segregation is reflected in visual temporal acuity: the ability to perceive a small temporal gap between two identical stimuli. Disruption of this balance may lead to impairment of perceptual organization processes. Notably, schizophrenia, a condition characterized by unusual perceptual experiences, has been associated with abnormal temporal processing of sensory stimuli and aberrant oscillations. We asked a large cohort of healthy participants to complete an online version of the two-flash fusion task and two questionnaires for schizotypal personality traits to investigate individual differences in the temporal resolution of perception, particularly its relationship with anomalous perceptual experiences. We found that two-flash discrimination acuity declines with age and that schizotypal traits are associated with better performances. Although this association was strong for perceptual and cognitive subscales, we found that this result could not be attributed to response biases (e.g., hallucination of two flashes). While these results appear to contrast with findings of slower alpha rhythms and sensory processing in schizotypy, we propose that a faster visual rate could be the consequence of an oscillopathy or a disconnection between different sensory modalities and their physiological pacemaker.

Information Avoidance in Consumer Choice: Do Avoidance Tendencies and Motives Vary by Age?

Prior research suggests that older adults seek less information in consumer choices than younger adults do. However, it remains unclear if intentional information avoidance plays a role in such effects. To test this possibility, we examined age differences in deliberate information avoidance in consumer decisions and explored a range of potential motives. Adult lifespan samples completed two pre-registered online studies, which assessed information avoidance using a slider scale (Study 1, N =195) and a forced-choice task (Study 2, N = 500). In Study 1, age differences in information avoidance were not significant, but methodological limitations could have obscured age effects. In Study 2, age was associated with higher information avoidance. Avoidance was higher among participants who reported that the information would not impact decision preferences, would elicit more negative affect, and would be useless. Although age was associated with lower perceived impact on decision preferences and lower concerns about affective responses, age differences in information avoidance remained significant when these variables were statistically controlled. In conclusion, in the context of consumer choices, deliberate information avoidance is higher among older consumers. Thus, interventions to promote the acquisition of relevant information would benefit from being tailored to the target age group.

Morningness-Eveningness Preference, Time Perspective, and Passage of Time Judgments

Recent studies have shown that making accurate passage of time judgments (POTJs) for long-time intervals is an important cognitive ability. Different temporal domains, such as circadian typology (biological time) and time perspective (psychological time), could have an effect on subjective POTJs, but few studies have investigated the reciprocal influences among these temporal domains. The present study is the first systematic attempt to fill this gap. A sample of 222 participants (53.20% females; 19-60 years) filled in the Zimbardo Time Perspective Inventory for the measurement of time perspective, the reduced version of the Morningness-Eveningness Questionnaire (rMEQ) for chronotypes, and an ad-hoc questionnaire assessing sleep habits during weekdays and the weekend (for social jetlag). The POTJ was measured using a modified version of a pictorial timeline presented at five different moments. Also, participants judged how different temporal expressions were related to the past, present, and future along a 7-point Likert scale. After confirming the association between eveningness and present-hedonism orientation and morningness and future-orientation, we found that evening-types produced higher scores for future expressions. The subjective POTJ expressed in minutes was predicted by Deviation from Balanced Time (DBTP), present-fatalism orientation, and social jetlag. Finally, the rMEQ score, past-positive orientation, and DBTP predicted the difference between subjective and objective POT. The results are discussed offering an explanation in terms of the interconnections between circadian typology, individual time perspective, and the sense of the POT, suggesting the multicomponent nature of the concept of time.

Is Reliance on the Affect Heuristic associated with Age?

OBJECTIVES

With age, decision makers rely more on heuristic and affect-based processing. However, age differences have not been quantified with respect to the affect heuristic which derives judgments based on positive and negative feelings towards stimuli and concepts. The present study examined whether reliance on the affect heuristic is associated with age, whether these patterns vary by task type, and which covariates account for age effects.

METHOD

In a pre-registered study, an adult lifespan sample (N = 195, 21 - 90 years, Mage = 52.95, 50% female, 71% non-Hispanic White) completed a battery of cognitive, personality, and socioemotional covariates as well as three established affect heuristic tasks: (1) a risk-benefit task, (2) a dread-inference task, and (3) an affect-impact task. Reliance on affect was indexed through (1) a negative relationship between perceived food risks and benefits, (2) a positive relationship between feelings of dread and statistical inferences about mortality risks, and (3) a positive relationship between affective responses and impact judgments when evaluating catastrophes.

RESULTS

For all three tasks, usage of the affect heuristic was documented at the group and the individual level. Contrary to hypotheses, age was not associated with affect heuristic use for any of the tasks. Affect heuristic indices did not correlate across tasks and showed no consistent associations with the covariates.

DISCUSSION

Results suggest that the use of affect-based heuristics is context- or stimulus-dependent rather than a stable, age-associated trait. Further research is needed to validate the present results across additional domains, tasks, and stimulus types.

Age Differences in Media Consumption and Avoidance With Respect to COVID-19

BACKGROUND

Older versus younger adults are at greater risk from COVID-19, but descriptive data show they are less likely to seek out related information in the media, although underlying mechanisms remain unclear.

METHODS

A representative adult lifespan sample (N = 500) completed a pre-registered online study assessing changes in media consumption in response to the pandemic, self-reported and behavioral media avoidance, avoidance motives, and demographic, socioemotional, and cognitive covariates.

RESULTS

Age was associated with reduced media consumption and higher behavioral media avoidance, but lower self-reported media avoidance and lower endorsement of specific avoidance motives. Age differences in aspects of affect, motivation, and cognition statistically accounted for variations in behavioral avoidance but not for the other age effects.

DISCUSSION

Age differences in media use in the context of the COVID-19 pandemic are not explained by deliberate avoidance intentions and motives but associated with broader age variations in socioemotional and cognitive functioning.

Age Effects in Sequence-Construction for a Continuous Cognitive Task: Similar Sequence-Trends but Fewer Switch-Points

OBJECTIVES

Many real-life settings require decision makers to sort a predetermined set of outcomes or activities into a preferred sequence and people vary in whether they prefer to tackle the most challenging aspects first, leave them for the last, or intersperse them with less challenging outcomes. Prior research on age differences in sequence-preferences has focused on discrete and hypothetical events. The present study expands this work by examining sequence-preferences for a realistic, continuous, sustained, and cognitively challenging task.

METHODS

Participants (N = 121, aged 21-86) were asked to complete 10 min of a difficult cognitive task (2-back), 10 min of an easy cognitive task (1-back), and 10 min of rest over the course of a 30-min interval. They could complete the tasks in any order and switch tasks as often as they wished and they were rewarded for correct performance. Additional measures included affective and physiological responses, task accuracy, time-perspective, and demographics.

RESULTS

The majority of participants constructed sequences with decreasing task difficulty. Preferences for the general trend of the sequence were not significantly related to age, but the number of switches among the tasks decreased with age, and task-switching tended to incur greater accuracy decrements among older as compared to younger adults.

DISCUSSION

We address potential methodological concerns, discuss theoretical implications, and consider potential real-life applications.

Preferences for Temporal Sequences of Real Outcomes Differ Across Domains but do not Vary by Age

OBJECTIVES

People's preferences for temporal sequences of events have implications for life-long health and well-being. Prior research suggests that other aspects of intertemporal choice vary by age, but evidence for age differences in sequence-preferences is limited and inconclusive. In response, the present research examined age differences in sequence-preferences for real outcomes administered in a controlled laboratory setting.

METHODS

A pilot study examined sequence-preferences for aversive electrodermal shocks in 30 younger and 30 older adults. The main study examined sequence-preferences for electrodermal shocks, physical effort, and monetary gambles in an adult life-span sample (N = 120). It also examined emotional and physiological responses to sequences as well as underlying mechanisms including time perception and emotion-regulation.

RESULTS

There were no significant age differences in sequence-preferences in either of the studies, and there were no age differences in responses to sequences in the main study. Instead, there was a domain effect with participants preferring decreasing sequences for shocks and mixed sequences for effort and money.

DISCUSSION

After considering potential methodological limitations, theoretical contributions and implications for real-life decisions are discussed.

Different Future Time Perspectives Interplay in Predicting Life Satisfaction

Abstract. This study addresses prior mixed findings on the relationship between future time perspective (FTP) and well-being as well as examines the associations between three aspects of FTP and life satisfaction in the health and friendship domains. 159 Germans, 97 US Americans, and 240 Hong Kong Chinese, aged 19–86 years, completed a survey on future self-views (valence) and life satisfaction. They also reported the extent to which they perceived future time as expanded vs. limited (time extension) and meaningful (openness). Findings revealed that individuals with more positive future self-views had higher satisfaction. However, those who perceived their future as more meaningful or perceived more time in their future reported higher satisfaction even when future self-views were less positive.

Women Overestimate Temporal Duration: Evidence from Chinese Emotional Words

Numerous studies have proven the effect of emotion on temporal perception, using various emotional stimuli. However, research investigating this issue from the lexico-semantic perspective and gender difference remains scarce. In this study, participants were presented with different types of emotional words designed in classic temporal bisection tasks. In Experiment 1 where the arousal level of emotional words was controlled, no pure effect of valence on temporal perception was found; however, we observed the overestimation of women relative to men. Furthermore, in Experiment 2, an orthogonal design of valence and arousal with neutral condition was employed to study the arousal-mechanism of temporal distortion effect and its difference between genders. The results showed that the gender difference observed in Experiment 1 was robust and was not influenced by valence and arousal. Taken together, our findings suggest a stable gender difference in the temporal perception of semantic stimuli, which might be related to some intrinsic properties of linguistic stimuli and sex differences in brain structure as well as physiological features. The automatic processing of time information was also discussed.

Age Patterns in Mental Representations of Time: Underlying Constructs and Relevant Covariates

BACKGROUND/STUDY CONTEXT

Research suggests that mental representations of time encompass multiple distinct aspects that vary with age, but prior studies rarely assessed more than one aspect of time perception and did not systematically consider relevant covariates. This lack of integration across studies hampers theory building and limits a deeper understanding of underlying constructs.

METHODS

Five widely used and conceptually distinct measures of time perception (i.e., perceived life position, global future horizons, future orientation and planning, self-continuity, and the temporal extension of episodic future thought) were administered to a demographically stratified adult life-span sample. Theoretically implicated covariates, including cognition, current affect, personality, and subjective health, were also assessed.

RESULTS

Principle component analyses suggested a four-component solution. Perceived life position and global future horizons formed a single component reflecting subjective life span; the remaining measures each constituted separate components. The life span component and episodic future thought were negatively associated with age, self-continuity was positively associated with age, and future orientation did not vary by age. Among the covariates, mental and physical health showed the most pronounced associations with time perceptions, but the direction of effects varied across components.

CONCLUSION

Findings suggest that mental representations of time encompass multiple components that show distinct age patterns and associations with covariates. Implications for theory building and practical applications are discussed.

A New Law for Time Perception

Effects of sex and handedness on the perception of temporal durations from 1 to 20 s were studied. A total of 80 male and 40 female participants were divided equally into left-handed and right-handed subgroups. Using an empty interval production procedure, each person estimated durations of 1, 3, 7, and 20 s, respectively, 50 times each. The order of presentation was randomized across participants but yoked across the sexes in each of the respective handedness subgroups. Results showed significant sex differences but no effects for handedness. One important facet of this sex effect was expressed in a consistent intercept difference in the identified relationship that linked the log-linear size of the absolute error of estimation against the logarithmic magnitude of the target duration at which such error was recorded. This new finding provides a new descriptive, empirical relationship for time perception of brief temporal intervals. The potential methodological, evolutionary, and cognitive reasons for this lawful relationship are discussed.

[Subjective time left in life and precautionary relocation planning in the last half of life]

BACKGROUND

Many people wish to remain in current residence for as long as possible. Nonetheless, they do think about their residential future. For older people the question of where to live must be considered with respect to age-related changes and continuity. So far only little research has been focused on the influence of the subjective perception of remaining lifetime until death on plans for the future, for example regarding relocation.

OBJECTIVE

This study investigated the influence of the subjective perception of time left to live on relocation planning and its timing in the further course of life.

MATERIAL AND METHODS

The data were obtained from a paper-pencil questionnaire including 2156 persons aged 50 years and older (average age  65.5 years, SD = 9.7 years, range 50-94 years, 51.1 % female) who were asked about their wishes and plans for the future, particularly about their relocation considerations and the subjective perception of remaining time until death.

RESULTS

Approximately 39 % of the subjects considered relocation in the further course of life. Besides social demographics, current housing and the state of health, the subjective time left in life had a significant influence on the consideration of relocation and its timing in the further course of life. Persons who perceived their time horizon as limited considered relocation later in life (temporizing relocation planning) than persons who perceived themselves to have more time left in life. Their temporal occurrence of precautionary relocation planning is embedded earlier in the course of life.

CONCLUSION

Thoughts about the residential future of older people should be considered not only in connection with the content of these wishes but also related to the future time perspective and the timing in the further course of life. This can be of assistance in consultation and decision-making situations.

Using a pictorial timeline to assess age-related changes in time estimation of daily events

How do older adults compare with younger adults in estimating the timing of daily events, such as heating a meal, keeping an appointment, or taking medication? In Experiment 1, we used a pictorial timeline method to examine age-related changes in how people estimate the time involved in daily events. We also conducted a spatial processing task to control for possible age-related bias in spatial processing. Findings showed that older adults projected smaller windows of time on the timeline to represent the duration of events than did younger adults, which indicates that older adults underestimate time duration. However, older adults also projected smaller windows in spatial task, which creates ambiguity in interpreting the reduced duration estimates among older adults. In Experiment 2, we administered an improved timeline task and spatial task that were comparable in difficulty between age groups and used defined endpoints of the reference line. Consistent with findings from Experiment 1, older adults projected a smaller time window than their younger counterparts, whereas the two age groups showed no differences in estimating spatial distances in the improved spatial experiment. Taken together, our findings suggest that older adults make shorter estimates of the duration of an event than younger adults, and that these age differences are due to age-related differences in orientation to time rather than to a general bias in spatial processing.

Temporal horizons in pain management: understanding the perspectives of physicians, physical therapists, and their middle-aged and older adult patients

PURPOSE

The management of chronic noncancer pain (CNCP) involves trade-offs between immediate and delayed consequences of various treatments. Temporal trade-offs may be particularly salient for older adults because of age-related differences in prognosis and perceptions of future time. This study examined how perceptions of time influence the management of CNCP among patients and providers with particular emphasis on age differences.

DESIGN AND METHODS

Focus groups were conducted with 28 CNCP patients (5 groups), 21 physicians (4 groups), and 23 physical therapists (3 groups). Audiotapes were transcribed and analyzed using standard qualitative methods.

RESULTS

Analyses identified multiple aspects of time perceptions that are relevant to the management of CNCP: the long-term prognosis, the time horizon used for concrete treatment planning, and concerns about future side effects. Although there was some overlap, these aspects showed divergent patterns across age groups and between patients and providers. Patients and providers agreed that pain is more stable and chronic in older adults. Time horizons in treatment planning differed between patients who were present-focused and providers who were focused on longer term effects, but treatment horizons did not differ by patient age. Finally, although providers were more concerned about future side effects in older people, patients' concerns did not differ by age.

IMPLICATIONS

Time horizons have practical implications for the quality of the patient-provider relationship and self-management of CNCP. A better understanding of the underlying mechanisms could inform interventions to reduce age disparities in pain care.

Age, time, and decision making: from processing speed to global time horizons

Time and time perceptions are integral to decision making because any meaningful choice is embedded in a temporal context and requires the evaluation of future preferences and outcomes. The present review examines the influence of chronological age on time perceptions and horizons and discusses implications for decision making across the life span. Time influences and interacts with decision making in multiple ways. Specifically, this review examines the following topic areas: (1) processing speed and decision time, (2) internal clocks and time estimation, (3) mental representations of future time and intertemporal choice, and (4) global time horizons. For each aspect, patterns of age differences and implications for decision strategies and quality are discussed. The conclusion proposes frameworks to integrate different lines of research and identifies promising avenues for future inquiry.

On the left hand of time

The present experiment examined the effects of sex and handedness on the perception of brief intervals up to 20 s in duration. In order to obtain participants with sufficiently high scores on a scale of handedness, we screened 1,276 people; the process yielded 16 men and 16 women eligible for testing. In an empty production procedure, each person estimated 4 intervals of 1, 3, 7, and 20 s, respectively, using both their preferred and nonpreferred hands to provide recorded responses. The order of presentation was randomized across participants but yoked across the sexes in each of the respective handedness subgroups. Results indicated significant effects for handedness in conjunction with the hand used to make the respective response. The pattern of these interactive effects differed between male and female participants, however. These results are discussed in terms of a hemispheric account of interval timing control and potential sex difference in hemispheric specialization.

The effects of sex, age, and interval duration on the perception of time

The present experiment examined the interactive effects of sex, age, and interval duration on individual's time perception accuracy. Participants engaged in the duration production task and subsequently completed questionnaires designed to elicit their temporal attitudes. The overall group of 100 individuals was divided evenly between the sexes. Five groups, each composed of 10 males and 10 females, were divided by decades of age ranging from 20 to 69 years old. The specific time estimation task was an empty interval production procedure composed of 50 trials on each of four different intervals of 1, 3, 7, and 20 s, respectively. The presentation orders of these intervals were randomized across participants but yoked across the sexes within each of the respective age groups. Analysis of the production results indicated significant influences for the sex of the participant while age did not appear to affect estimates of these short durations. Temporal attitudes, as reflected in responses to time questionnaire inquiries, did however exhibit significant differences across age. The contending theoretical accounts of such sex and age differences are considered and explanatory accounts that present a synthesis of endogenous and exogenous causal factors are discussed in light of the present pattern of findings.
