The development of automaticity in accessing number magnitude

This study traces developmental changes in automatic and intentional processing of Arabic numerals using a numerical-Stroop paradigm. In Study 1, university students compared the numerical or physical size of Arabic numerals varying along both dimensions. In Study 2, first graders (mean age = 6 years 6 months), third graders (mean age = 8 years 4 months), and fifth graders (mean age = 10 years 3 months) were tested to examine developmental changes in numerical and physical comparisons. In the numerical comparison task, a size congruity effect was found at all ages (i.e., relative to a neutral control, congruent physical sizes facilitated, and incongruent sizes interfered with, the numerical comparison). The pattern of facilitation and interference, however, was modulated by age. In the physical comparison task, the incongruity between physical and numerical size affected only older children and adults. These findings strongly suggest that the automatization in number processing is achieved gradually as numerical skills progress.

Gender differences in visuo-spatial processing: the importance of distinguishing between passive storage and active manipulation

The study here reported investigates the hypothesis that gender differences in visuo-spatial abilities are mainly confined to active processing tasks. Male and female participants were required to perform passive tasks involving the recall of previously memorized positions within matrices of different sizes, as well as active tasks in which they had to mentally follow a pathway in the same matrices. The results confirmed that male superiority became evident as the active processing requirements increased while only marginal gender difference was reported in passive tasks. To strengthen the specific role of the active-passive distinction in identifying gender differences, confounding factors such as type of material and use of verbal strategies were ruled out. These findings, in line with a number of studies on individual differences, high-light the importance of addressing visuo-spatial ability as a multicomponential cognitive function which entails different type of visuo-spatial processing or mechanisms (i.e., active processing and passive storage of information) rather than as a unitary concept.

Storage and retrieval of addition facts: the role of number comparison

It is proposed that arithmetical facts are organized in memory in terms of a principle that is unique to numbers--the cardinal magnitudes of the addends. This implies that sums such as 4 + 2 and 2 + 4 are represented, and searched for, in terms of the maximum and minimum addends. This in turn implies that a critical stage in solving an addition problem is deciding which addend is the larger. The COMP model of addition fact retrieval incorporates a comparison stage, as well as a retrieval stage and a pronunciation stage. Three tasks, using the same subjects, were designed to assess the contribution of these three stages to retrieving the answers to single-digit addition problems. Task 3 was the addition task, which examined whether reaction times (RTs) were explained by the model; Task 1 was a number naming task to assess the contribution of the pronunciation stage; Task 2 was a magnitude comparison task to assess the contribution, if any, of the comparison stage. A regression equation that included just expressions of these three stages was found to account for 71% of the variance. It is argued that the COMP model fits not only the adult RT data better than do alternatives, but also the evidence from development of additional skills.

Number processing and calculation--normative data from healthy adults

Despite the high incidence of numerical deficits in neurological patients, little attention has been paid to the development of diagnostic tools. In fact, most of the published reports on acquired numerical disorders, whether single case or group studies, do not refer to standardised measures of performance providing little, if any, control data specifically collected for the examination. In this study we present data of 282 healthy controls of different age groups and educational levels in a new battery of Number Processing and Calculation (NPC). The NPC battery includes a total of 35 tasks, assessing different counting abilities, various aspects of number comprehension (such as parity and magnitude judgements), numerical transcoding, calculation, arithmetic reasoning and conceptual knowledge. Special attention is paid to the assessment of different calculation abilities, including simple fact retrieval, rule based processing, mental calculation and written calculation in all four operations. Moreover, text problem solving is assessed as well as the understanding of arithmetic principles. Thus, the NPC battery differs from the EC 301 battery proposed by Deloche et al., 1994 (Dellatolas, Deloche, Basso, & Claros-Salinas, 2001) and allows a more fine grained diagnosis which is relevant for planning targeted interventions. The battery is easy to administer and does not require special materials or equipment.

Numerical skills and aphasia

The aim of this study was to investigate numerical difficulties in 50 patients with left hemispheric lesions. Aphasic patients were grouped according to their type of aphasia diagnosed by the Aachener Aphasia Test. The overall error rate in various transcoding and calculation tasks was clearly correlated with the severity of the language deficit, global aphasics being the most impaired patients. Broca's and Wernicke's aphasics scored similarly at the quantitative level, and amnesic aphasics were less impaired. Interestingly, qualitative analysis of the errors indicated that each group presented with specific difficulties, partially reflecting the nature of the language problems. In simple calculation, multiplication was found to be the most impaired operation, in particular in Broca's aphasics. This result supports the hypothesis that the retrieval of multiplication facts is preferentially mediated by verbal processing. Calculation procedures were mainly impaired in Wernicke's and global aphasics.

The representation of arithmetical facts: evidence from two rehabilitation studies

We report the improvement following rehabilitation of two patients with a selective deficit on multiplication facts. The remediation experiments were conducted in specific designs to test a series of hypotheses about both the process of reacquisition and organisation of arithmetical facts in memory. The results show a significant and stable recovery and the pattern of reacquisition reflects the different strategy used by the patients to relearn the multiplication facts. Quantitative and qualitative changes in error patterns in the course of remediation reveal the underlying (re)organization of the memory network representing multiplication facts.

Subtraction bugs in an acalculic patient

We report a patient, MT, who presented a specific, though not isolated, deficit in written calculation. Despite a preserved knowledge of simple arithmetic - single-digit addition and subtraction - he failed systematically in multi-digit subtraction. The nature of errors was consistent across problems and reflected the application of a disturbed underlying algorithm. Moreover, the pattern of error observed mimies a very common finding in developmental studies on arithmetical procedure acquisition (Fuson, 1990, 1992, Young and O'Shea, 1981; VanLehn, 1986, 1990). The data suggest that, within calculation skills, syntax may exist as a system of stable, but inappropriate, rules which are independent of any underlying conceptual knowledge.

A deficit for arithmetical procedures: lack of knowledge or lack of monitoring?

A patient is described with a specific deficit for arithmetical procedures. Unlike in previously described cases, where the observed problems could be attributed to the systematic application of disturbed algorithms, this patient's difficulty seems to stem from an inability to monitor the sequence of operations that calculation procedures specify. Criteria are provided for distinguishing impairments in written calculation due to the application of defective knowledge of the procedures from those determined by lack of monitoring. The role of monitoring and control processes in different calculation components is also discussed.

Mathematical skills in Prader-Willi Syndrome

OBJECTIVES

This paper investigates mathematical skills in Prader-Willi Syndrome (PWS), a pathological condition because of congenital alterations of chromosome pair 15. The following questions were addressed: (1) Are mathematical skills in PWS relatively more impaired with respect to other cognitive functions (as has been repeatedly but anecdotally reported)?; and (2) What is the nature of the mathematical impairment?

METHODS

The first study employed the Wechsler Adult Intelligence Scale (WAIS) and an extensive battery of cognitive tasks for which norms are known. Both batteries include a mathematical section. The second study used a theoretically motivated series of mathematical tasks specifically designed to individually assess the different cognitive components underlying mathematical skills.

RESULTS

Mathematical skills were found to be the most impaired cognitive abilities together with short-term memory capacity. No specific mathematical domain was seen to be unaffected in PWS participants. The clearest deficits observed concern 'syntactic' processes in number transcoding, multiplication, number facts retrieval and calculation procedures.

CONCLUSION

Failure of mathematical skills is the most distinctive feature in the cognitive profile of PWS. However, to determine whether this is indeed a specific pattern of performance related to PWS, results must be compared with those obtained with patients manifesting other genetic disorders.

Relationships between sociocultural factors (gender, immigrant and socioeconomic background), peer relatedness and positive affect in adolescents

INTRODUCTION

During adolescence, experiencing positive emotions at school is important for motivation as well as for academic success and psychological well-being. In the present study, on the basis of Self-Determination Theory (SDT), we investigated the relationships between sociocultural factors (gender, immigrant and socioeconomic background), peer relatedness (acceptance and friendship) and positive affect at school.

METHODS

Data was based on a random sample of 36,712 tenth grade Italian adolescents. Their average age was 15.6 years (SD = 0.77), 50.6% were males, while 6.1% were first-generation immigrants and 3.8% were second-generation immigrants. Firstly, comparing latent means, we established peer relatedness and positive affect profiles of adolescents with different sociocultural backgrounds. Subsequently, we tested a structural equation model, based on SDT, according to which the effects of sociocultural factors on experiencing positive affect at school are mediated by peer relatedness dimensions.

RESULTS

Latent mean comparisons showed that immigrant adolescents, students with a lower-SES and girls had fewer friendships with their classmates, lower levels of positive affect at school and were less accepted by their peers. A well-fitting structural equation model corroborated the mediating role of acceptance and friendship, which accounted for 16% of variance in positive affect.

CONCLUSIONS

Due to sociocultural factors, some groups of adolescents proved to be more at risk of being socially excluded and of experiencing less positive affect at school. Moreover, our findings support the claim of SDT that the satisfaction of basic psychological needs, such as relatedness, is more important than sociocultural factors in determining adolescents' psychological well-being.

Physical Distancing Behavior: The Role of Emotions, Personality, Motivations, and Moral Decision-Making

OBJECTIVE

Physical distancing behavior (PDB) is a key disease prevention strategy for limiting the spread of COVID-19. In order to effectively encourage it among adolescents, it is necessary to understand the associated mental mechanisms. Health behavior theories suggest that emotions, personality, motivation, and moral disengagement could all play a role. On the basis of a longitudinal study, we investigated the importance of these factors in predicting PDB.

METHODS

The participants were 347 adolescents residing in Italy. Data were collected in four waves starting from 1 year before the pandemic. A structural equation model based on health behavior theory was tested.

RESULTS

After the COVID-19 national lockdown, adolescents experienced fewer positive emotions and more negative emotions compared with 1 year earlier. Nevertheless, these emotional changes, and adolescents' personality (except for openness to experiences), were not related to the adoption of PDB. Instead, the autonomous motivation of adolescents significantly predicted a higher likelihood to adopt PDB by increasing the intention to engage in this behavior and, more indirectly, by substantially decreasing moral disengagement, which was negatively related to PDB. In contrast, controlled motivation corresponded to significantly higher levels of moral disengagement and predicted less likelihood of adopting PDB.

CONCLUSIONS

Messages and interventions targeted at adolescents should be oriented towards supporting autonomy, emphasizing the personal and social value of PDB. Communications should avoid the use of coercive strategies based on eliciting emotions such as shame and guilt in adolescents who do not adopt PDB, which appear to trigger off mechanisms of moral disengagement.

From perceived autonomy support to intentional behaviour: Testing an integrated model in three healthy-eating behaviours

A motivational model integrating self-determination theory, the theory of planned behaviour, and the health action process approach was tested in three samples in three behavioural contexts: fruit and vegetable, breakfast, and snack consumption. Perceived support for autonomous (self-determined) forms of motivation from parents and autonomous motivation from self-determination theory were hypothesised to predict intention and behaviour indirectly via the mediation of attitude and perceived behavioural control from the theory of planned behaviour. It was also expected that planning strategies would mediate the effect of intention on behaviour. Relations in the proposed models were expected to be similar across the behaviours. A two-wave prospective design was adopted. Three samples of high-school students (total N = 1041; 59.60% female; M age = 17.13 years ± 1.57) completed measures of perceived autonomy support, autonomous motivation, theory of planned behaviour constructs, planning strategies and behaviour for each of the three behavioural contexts. Three months later, 816 participants (62,24% female; M age: 17.13 years, SD = 1.58) of the initial sample self-reported their behaviour referred to the previous three months. Structural equation models provided support for the key hypothesised effects of the proposed model for the three health-related behaviours. Two direct effects were significantly different across the three behaviours: the effect of perceived autonomy support on perceived behavioural control and the effect of attitude on intention. In addition, planning strategies mediated the effect of intention on behaviour in fruit and vegetable sample only. Findings extend knowledge of the processes by which psychological antecedents from the theories affect energy-balance related behaviours.

Active lifestyles in older adults: an integrated predictive model of physical activity and exercise

Physical activity and exercise have been identified as behaviors to preserve physical and mental health in older adults. The aim of the present study was to test the Integrated Behavior Change model in exercise and physical activity behaviors. The study evaluated two different samples of older adults: the first engaged in exercise class, the second doing spontaneous physical activity. The key analyses relied on Variance-Based Structural Modeling, which were performed by means of WARP PLS 6.0 statistical software. The analyses estimated the Integrated Behavior Change model in predicting exercise and physical activity, in a longitudinal design across two months of assessment. The tested models exhibited a good fit with the observed data derived from the model focusing on exercise, as well as with those derived from the model focusing on physical activity. Results showed, also, some effects and relations specific to each behavioral context. Results may form a starting point for future experimental and intervention research.

Impulsivity and Depressive Brooding in Internet Addiction: A Study With a Sample of Italian Adolescents During COVID-19 Lockdown

This contribution presents a study conducted on a sample of Italian adolescents (n = 411) in the period of the first COVID-19 lockdown. The study investigated the role and predictive weight of the impulsivity and depressive brooding variables on Internet addiction, using a hierarchical regression analysis. The participants were administered the Uso-Abuso e Dipendenza da Internet [Internet Use-Abuse and Addiction] (UADI-2), the Barratt Impulsiveness Scale-11 (BIS-11), and the Ruminative Response Scale (RRS). In terms of percentage distribution, 28% of the participants were in the full dependency range, while 34.7% demonstrated Internet abuse behavior. The results highlighted not only the predictive value of impulsiveness (β = 0.323) and ruminative thinking (β = 0.258), but also the role of gender (β = -0.205) on Internet addiction. Thus, male participants showed higher levels of Internet addiction, with higher scores on impulsiveness and brooding way of thinking. The study shows that the issue in question is significantly present among adolescents; in addition, not only targeted awareness programmes but also psycho-educational and clinical interventions to promote greater emotional and cognitive control would be necessary as a preventive and mitigating measure. Psychological interventions can help increase self-awareness, develop emotional regulation and impulse control, and correct maladaptive cognitions which in adolescents are mostly driven by a ruminative cognitive style.

Internet addiction in young adults: The role of impulsivity and codependency

Excessive Internet use has demonstrated comorbidity with other psychological symptoms and psychiatric disorders, as well as impairments in the management of daily life, relationships and emotional stability. Recent findings in the literature have consistently supported the relationship between impulsivity and Internet addiction. The present study hypothesized that, in addition to impulsivity, a further predictor of Internet addiction might be relational co-dependency, which is also associated in the literature with addiction phenomena, but mainly substance addiction. This paper investigates the role and predictive weight of impulsivity and codependency on Internet addiction on a sample of young adult university students (n = 481) by using a hierarchical regression analysis. The participants were administered the UADI-2, the BIS-11 and the SFCDS. In terms of percentage distribution, 38 % of the participants were in the dependency range, while 37.7 % demonstrated Internet abuse behavior. The results confirmed the role of impulsiveness (β = 0.312) and added to the literature by showing the significant role of relational codependency (β = 0.275), gender (β = 0.174) and age (β = 0.196). Thus, male participants were more dependent, more impulsive and more co-dependent, with increasing age in the given range (18-30). The present study shed light to the presence of this issue among young adults and that, as a preventive and restraining measure, there is a need not only for targeted awareness-raising programmes but also for interventions to promote greater emotional control and a more balanced management of personal relationships.

Personality Traits and Attitudes Toward Traffic Safety Predict Risky Behavior Across Young, Adult, and Older Drivers

In the last few decades, several studies have investigated the role of personality traits and attitudes toward traffic safety in predicting driving behaviors in diverse types of drivers across several countries. However, to the best of our knowledge, no studies so far have investigated the possible moderating role played by age in relation to predictors of accident risk. Answering this open question would provide information about the generalizability of the model across different subpopulations and would make possible the tailoring of the interventions to specific target groups. The study involved 1,286 drivers from three different age groups (young: n = 435; adult: n = 412; old: n = 439) which completed a questionnaire measuring drivers’ personality traits (i.e., anxiety, hostility, excitement seeking, altruism, normlessness), positive attitudes toward traffic safety, risky driving behaviors (i.e., errors, lapses, and traffic violations), accident involvement and number of traffic fines issued in the last 12 months. Multi-group Variance Based Structural Equation Modeling (VB-SEM) across the three age groups showed that the hypothesized model had a good fit with the data in all the three age groups. However, some pattern of relationships between the variables varied across the three groups, for example, if considering the direct effects of personality traits on risky driving behaviors, anxiety, altruism, and normlessness predicted violations only in young and adult drivers, whereas excitement seeking was associated with lapses only in young drivers; anxiety was a positive predictor of drivers’ errors, both in adult and older drivers, whereas excitement seeking predicted errors in adult and young drivers. On the other hand, attitudes significantly and negatively predicted violations and errors in all the three age groups, whereas they significantly and negatively predicted lapses only in young and older drivers. The results of the present study provided empirical basis to develop evidence-based road safety interventions differently tailored to the specific life’s stage of the drivers.

A mind-body intervention for stress reduction as an adjunct to an information session on stress management in university students

INTRODUCTION

This study describes the implementation of a mind-body intervention to reduce the perceived level of stress in a nonclinical group of university students. We used a novel approach including a single session of a mind-body technique known as the brain wave modulation (BWM) as an adjunct to a single information session on stress management.

METHODS

Three hundred and six students participated in the study. A quasi-experimental design was adopted: Students in the experimental group were exposed to an information session on stress management followed by a single session of the BWM, while the other students were exposed to the information session alone.

RESULTS

A 2 × 2 mixed factor analysis of variance demonstrated that the single session of the BWM was effective in reducing the perceived level of stress in the experimental group as compared to the control group.

CONCLUSION

The BWM is a very easy-to-learn technique that presents certain advantages over traditional mind-body methods.

The Evaluation of a Mind-Body Intervention (MBT-T) for Stress Reduction in Academic Settings: A Pilot Study

This study is aimed at evaluating the outcomes of mind-body transformation therapy (MBT-T), previously known as the creative psychosocial genomic healing experience© (CPGHE). The intervention was aimed at reducing the perceived level of stress in two non-clinical groups of students with different educational levels and different expertise in the domain of well-being. Whereas participants from the first group were first-year university students, participants from the second group were students attending a post-graduate program in psychotherapy. All participants (n = 159) were exposed to a single session of MBT-T, each group in a separate session. The results of two paired-samples t-tests, conducted separately on the two samples, showed that there was a statistically significant reduction in the participants' perceived level of stress between pre- and post-intervention states in both samples (t₈₈ = 5.39, p < 0.001; t₅₃ = 4.56, p < 0.001 respectively). The results, therefore, showed that a single session of MBT-T was beneficial in reducing the perceived level of stress in both first-year university students and students attending a post-graduate program in psychotherapy, regardless of educational level and expertise in the domain of well-being.

Number-Stroop performance in normal aging and Alzheimer's-type dementia

The number-Stroop paradigm was used to investigate changes in the inhibitory system and in numerical processing in healthy elderly and individuals with dementia of Alzheimer's type (DAT). The size-congruity effect (i.e., relative to neutral trials, incongruent pairs interfere and/or congruent pairs facilitate either numerical or physical comparison) was found in all groups, though the pattern of interference and facilitation varied across them. Overall, the selective attention breakdown was reflected by the increase in interference shown by the older group and the DAT group. On the other hand, the observation of a standard laterality effect andof automatic numerical processing in all groups suggests that access and retrieval of numerical information is relatively resistant to cognitive deterioration.

Doping Use in High-School Students: Measuring Attitudes, Self-Efficacy, and Moral Disengagement Across Genders and Countries

The main aim of this research was to test the factorial validity and measurement invariance across genders and countries of a set of instruments designed to assess high-school students' attitudes, self-regulatory efficacy, and moral disengagement with regard to doping. A second aim was to examine the criterion and predictive validity of these scales. In total, 402 high-school students from Italy, Romania, and Turkey (40.0, 25.1, and 34.9%, respectively; M age 14.78 years old; SD = 1.04; 52.8% females) completed questionnaires measuring attitudes toward doping, self-regulatory efficacy in refraining from doping, doping-specific moral disengagement, and intention to use doping substances. A confirmatory factor analysis (CFA) supported our expectations with regard to the factor structure of the scales. Multigroup CFAs provided evidence for the full equivalence of the measures across males and females and partial equivalence of the measures across the three countries. The results of the latent mean comparison showed that male students had lower levels of self-regulatory efficacy than females and that Romanian and Turkish students had higher levels of moral disengagement and lower level of self-regulatory efficacy than Italian students. Finally, the results of a structural equation modeling supported the hypothesis that the proposed model predicted students' intentions to use doping, thus generally confirming the criterion and the predictive validity of the measures. These findings suggested the validity of a set of instruments measuring attitudes toward doping, self-regulatory efficacy to refrain from doping, and doping-specific moral disengagement in high-school students from a cross-gender and a cross-cultural perspective and provided meaningful estimates of the differences in the three factors between males and females as well as between Italian, Romanian, and Turkish high-school students.

Effect of online counselling on emotional outcomes during the COVID‐19 pandemic: An innovative group intervention for university students using the Brain Wave Modulation Technique

Young people's mental health problems are a matter of concern during the COVID‐19 pandemic. Counselling services for university students by means of telemental support can help them to deal with psychological issues that they may be facing due to the pandemic. The present study investigated the effects of four once‐weekly online counselling sessions based on a mind‐body technique (the Brain Wave Modulation Technique; BWM‐T) on enhancing positive affect and on reducing negative affect and anxiety in a sample of 54 university students (96.3% females; M_age = 21.31 years, SD = 2.09). An experimental design was conducted: the participants were randomly assigned to the intervention group, which received 15 min of a guided online BWM‐T session, or to the control group, which watched a 15‐min video on how to sustain their psychological well‐being. The results of a two‐factor mixed‐design analysis of variance (ANOVA) showed that the participants in the intervention group reported a significant increase in positive affect and a decrease in negative affect over time compared to those in the control group. They also reported a slight decrease in state anxiety compared to the control group, although this was just short of statistical significance. The information provided by this study, regarding emotional outcomes among university students after four brief online counselling sessions, suggests that such interventions could be an effective and sustainable way to reinforce young people's mental health during the COVID‐19 pandemic, as well as later in their university careers and adult lives.

Letter and number writing in agraphia: a single-case study

The gradual recovery of writing abilities of a patient whose processing of Arabic numerals and alphabetic script evolved differently over time is reported. Writing of multidigit numerals was achieved when writing of letters was nil. However, despite an initial advantage for numbers, the final examination disclosed fluent and correct writing of letters and words together with specific syntactic difficulties in complex Arabic numerals. The differential improvement for Arabic and alphabetic stimuli is partly explained in terms of different processing requirements rather than in terms of script-specific mechanisms only.

Improving University Students' Mental Health During the COVID-19 Pandemic: Evidence From an Online Counseling Intervention in Italy

Background

The mental health of university students is significantly affected when faced with public health emergencies and requires specific interventions to help support and prevent any long-lasting effects that the pandemic may have on their mental health status. This study aims to evaluate the impact of an online individual counseling intervention provided by the University of Foggia and carried out during the COVID-19 pandemic on the mental health status of a sample of university students.

Methods

32 Italian undergraduate students took part in a one-group pretest-posttest research design. The data was gathered in two times: before the start of the counseling intervention (T1), positive and negative affect, satisfaction with life, global mental distress, anxiety, stress, and future time perspective were collected, at the end of the counseling intervention (T2), the same dimensions were measured. A one-way repeated measures multivariate analysis of variance (MANOVA) was performed, and single Bonferroni-corrected dependent t-tests were conducted on variables showing a significant change over time.

Results

The results showed that positive affect, subjective well-being, and future time perspective increased significantly after the intervention. In contrast, the participants reported significantly lower levels of negative affect, global mental distress, state and trait anxiety, as well as perceived stress over time.

Conclusions

The study demonstrates the promising impact of online counseling intervention and its efficient contribution in promoting the well-being of university students. The results contribute to the ongoing debate concerning the psychological impact of the COVID-19 pandemic on young adults, helping professionals develop more efficient clinical and psychological interventions.

A Psychosocial Genomics Pilot Study in Oncology for Verifying Clinical, Inflammatory and Psychological Effects of Mind-Body Transformations-Therapy (MBT-T) in Breast Cancer Patients: Preliminary Results

Several studies have highlighted the key role of chronic inflammation in breast cancer development, progression, metastasis, and therapeutic outcome. These processes are mediated through a variety of cytokines and hormones that exert their biological actions either locally or distantly via systemic circulation. Recent findings suggest that positive psychosocial experiences, including psychotherapeutic interventions and therapeutic mind-body protocols, can modulate the inflammatory response by reducing the expression of genes/proteins associated with inflammation and stress-related pathways. Our preliminary results indicate that a specific mind-body therapy (MBT-T) could induce a significant reduction of the release of different cytokines and chemokines, such as SCGFβ, SDF-1α, MCP3, GROα, LIF, and IL-18, in the sera of breast cancer patients compared to a control group, suggesting that MBT-T could represent a promising approach to improve the wellness and outcome of breast cancer patients.

Riding the Adolescence: Personality Subtypes in Young Moped Riders and Their Association With Risky Driving Attitudes and Behaviors

The aim of the present study was to identify sub-types of moped riders based on a cluster analysis of specific personality characteristics (i.e., driving anger, anxiety, angry hostility, excitement-seeking, altruism, normlessness, and driving locus of control) within a large sample of Italian adolescents. The study had also the aim to compare the emerged sub-types of moped riders on measures of attitudes toward safe driving, risky driving behaviors (e.g., rule's violations and speeding, not using helmet, drinking and driving, etc.), and self-reported tickets and accident involvement. One thousand two hundred seventy-three Italian high school students aged from 13 to 19 years (mean_age = 15.43, SD = 0.98) with a valid driving license for moped participated to the study. Results revealed three sub-types of moped riders (namely risky, worried and careful moped riders), which differ significantly for risky driving behaviors, attitudes toward traffic safety, risk perception, and self-reported accident involvement. Importantly, the results of the present study showed that the personality and behavioral characteristics of the three sub-groups of moped riders substantially resembled those identified by previous studies with vehicle drivers of different ages; thus, empirically supporting the notion that certain combinations of personality characteristics are associated with risk driving tendencies and behaviors in both young moped riders and car drivers. Safe driving interventions can tackle risky driving beliefs and behavioral tendencies in young moped riders and car drivers by tailoring their messages according to the personality sub-types of the target groups.
