Self-concept as a risky driver: Mediating the relationship between racing video games and on-road driving violations in a community-based sample

PurposeThe mediating relationship of self-conceptions as a risky driver on self-reported driving violations was examined for players of “drive’em up” and “circuit” racing video games using an Internet survey of automobile and racing club members. Structural equation modelling (SEM) tested Fischer et al. (2012) extended socio-cognitive model on the effects of risk-glorifying media on cognitions and actions.MethodAn Internet questionnaire was developed and relied upon validated instruments or questions derived from previous surveys. Driver club members were asked about: (1) their frequency of video game playing, (2) self-perceptions as a risky driver and (3) self-reported driving violations. SEM was performed to examine mediating effects of racing video game playing on self-reported driving violations.ResultsPlaying “drive‘em up” video games positively predicted risky self-concept (β = .15, t = 2.26), which in turn, positively predicted driving violations (β = .73, t = 8.63), while playing “circuit racing” games did not predict risky self-concept, although risky self-concept did predict driving violations (β = .72, t = 8.67).ConclusionsSelf-concept as a risky driver mediated the relationship between racing video game playing and self-reported driving violations for “drive’em up”, but not for “circuit racing” video games. These findings are congruent with Fischer and colleagues’ experimental model that self-concept as a reckless driver mediated the relationship between racing video game playing for “drive’em up”, but not for “circuit racing” games and risk-taking behavior in a video of road traffic scenarios.     

Indian mate preferences: Continuity,sex differences,and cultural change across a quarter of a century

Expressed mate preferences provide unique windows into evolved mating psychology. The current study used two research instruments—one ranking and one rating procedure—to examine mate preferences in India. We compared modern Indians (n = 536) with a more modest Indian sample studied a quarter of a century earlier (n = 105) to test the hypothesis that sex-specific mate preferences—as hypothesized by parental investment theory—would persist during this time period. Mate preferences for mutual attraction and love remained important and invariant over time, despite India’s history of arranged marriages. Sex differences in mate preferences for cues to fertility (youth, physical attractiveness) and resources (good financial prospects, social status) remained relatively invariant over time. Several changes in mate preferences emerged, including a greater preference for mates who are “creative and artistic,” “ambitious and industrious,” and “a good cook and housekeeper” for both sexes. Despite cultural changes in India over the past 25 years, evolved mate preferences have persisted during this time period. Discussion highlights limitations of this research.     

An evaluation of lineup presentation,weapon presence,and a distinctive feature using ROC analysis

We conducted an experiment (N = 2675) including both laboratory and online participants to test hypotheses regarding important system and estimator variables for eyewitness identification. Simultaneous lineups were compared to sequential lineups with the suspect presented early versus late because there is evidence that suspect position could be an important factor determining a simultaneous versus sequential advantage in guilty-innocent suspect discriminability. We also manipulated whether or not the perpetrator held a weapon or had a distinctive feature on his face, to re-evaluate recent evidence that these factors interact. Overall, the simultaneous lineup yielded higher discriminability than the sequential lineup, and there was no effect of sequential position. Discriminability was higher when the perpetrator had no weapon, but only when no distinctive feature was present. We conclude with a discussion of the importance of exploring interactions between system and estimator variables using Receiver Operating Characteristic (ROC) analysis.     

Under what conditions do lay people and health professionals accept a breach of doctor-patient confidentiality regarding a patient with signs of terrorist radicalization?

IntroductionConfidentiality is crucial to the establishment of a strong patient-physician relationship. However, certain situations create a dilemma for the physician who is faced with the choice of either respecting medical confidentiality or protecting others from a serious risk of violence.ObjectiveThis study aimed to observe how lay people and health professionals assessed the acceptability of breaching confidentiality when a physician is confronted to a patient showing signs of terrorist radicalization.MethodA total of 228 participants (174 from the general population and 54 health professionals) judged the acceptability of 54 scenarios which were constructed through the orthogonal combination of 4 factors frequently mentioned in the literature: presence of a “Psychiatric disorder”; “Signs of radicalization”; “Projects of violence”; “Collegiality”. Variance and cluster analyses were performed on all the raw data.ResultsResults showed that all factors influenced the judgment of participants but that “Psychiatric disorders” had a weaker impact. Five clusters were identified: “Favorable if collegiality” (n = 23); “Favorable to breach confidentiality” (n = 77); “Unfavorable to breach confidentiality” (n = 26); “Sensitive to all factors” (n = 71); “Favorable if violence” (n = 31), respectively with mean ratings of 5.87, 8.42, 3.64, 6.30 and 7.16, on an acceptability scale of 0–10.ConclusionThe importance that the great majority of participants attribute to these factors indicates that they influence their judgments in this specific context.     

Measurement and comparative analysis of driver’s perception–reaction time to green phase at the intersections with and without a countdown timer

This paper proposes a method based on digital image processing for measuring drivers’ perception–reaction time (PRT) to the green phase. The detection of the onset of a green signal was based on the RGB color model. The detection of the start of the vehicle was based on the frame difference. The driver’s perception–reaction time was equal to the difference between the frame of the onset of the green signal and the frame of the start of the vehicle divided by the video frame rate. Drivers’ PRT with and without a countdown timer were comparatively analyzed. First, the means and variances of drivers’ PRT with a timer and without a timer were compared. Second, Normal, Lognormal, Gamma and Weibull distributions were used to fit the PRT data. Third, the fuzzy c-means clustering was utilized for PRT classification and comparison. The results show that the method for measuring drivers’ PRT based on digital image processing was effective. The drivers’ PRT was decreased from 2.12 s to 1.48 s with countdown signals. Weibull distribution appeared to best fit the PRT with No-Timer and Lognormal distribution appeared to best fit the PRT with Timer. The PRT data were classified into three groups: “Fast”, “Moderate” and “Slow”. Clustering centers without Timer were 1.16 s, 2.47 s and 3.98 s respectively. Clustering centers with Timer were 0.95 s, 1.64 s and 2.70 s respectively. The clustering centers can be regarded as reference values of drivers’ starting response for microscopic traffic simulation software.     

The utility of single-item readiness screeners in middle school

This study examined the benefit of utilizing one-item academic and one-item behavior readiness teacher-rated screeners at the beginning of the school year to predict end-of-school year outcomes for middle school students. The Middle School Academic and Behavior Readiness (M-ABR) screeners were developed to provide an efficient and effective way to assess readiness in students. Participants included 889 students in 62 middle school classrooms in an urban Missouri school district. Concurrent validity with the M-ABR items and other indicators of readiness in the fall were evaluated using Pearson product-moment correlation coefficients, with the academic readiness item having medium to strong correlations with other baseline academic indicators (r = ± 0.56 to 0.91) and the behavior readiness item having low to strong correlations with baseline behavior items (r = ± 0.20 to 0.79). Next, the predictive validity of the M-ABR items was analyzed with hierarchical linear regressions using end-of-year outcomes as the dependent variable. The academic and behavior readiness items demonstrated adequate validity for all outcomes with moderate effects (β = ± 0.31 to 0.73 for academic outcomes and β = ± 0.24 to 0.59 for behavioral outcomes) after controlling for baseline demographics. Even after controlling for baseline scores, the M-ABR items predicted unique variance in almost all outcome variables. Four conditional probability indices were calculated to obtain an optimal cut score, to determine ready vs. not ready, for both single-item M-ABR scales. The cut point of “fair” yielded the most acceptable values for the indices. The odd ratios (OR) of experiencing negative outcomes given a “fair” or lower readiness rating (2 or below on the M-ABR screeners) at the beginning of the year were significant and strong for all outcomes (OR = 2.29 to OR = 14.46), except for internalizing problems. These findings suggest promise for using single readiness items to screen for varying negative end-of-year student outcomes.     

Fighting ability influences mate value in late adolescent men

Several studies have demonstrated the relationship between handgrip strength (HGS) and fighting ability in men, which is a relevant trait for intrasexual competition to increase the probability of obtaining a mate. However, few studies have determined a relationship between fighting ability and men’s self-perceived capacity to find, attract and retain a mate. This capacity is a complex compound of several traits that evolutionary psychology has called mate value. In the present study, in a population of late adolescent men from Chile (M ± SD = 16.94 ± .89 years), we explored the relationship between fighting ability, estimated by both HGS and a self-perceived fighting ability questionnaire, and mate value, assessed with a self-perceived mate value components questionnaire. The results show a strong influence of fighting ability on mate value. This influence affects the subscales of “views from the opposite sex”, “sociality” and “relationship history”. However, we did not find an effect on the subscales of “wealth”, “parenting” or “fear to failure”. The relationship between mate value and fighting ability indicates that fighting ability is a relevant component in understanding men’s reproductive behaviour, including intrasexual competition and intersexual selection. This effect was observed in adolescents, who have less mating experience than adults.     

The relationship between computer-game preference,gender, and mental-rotation ability

This study examined how computer-game preference relates to mental-rotation test (MRT) performance and to gender differences. Subjects were 861 German secondary-school children (mean age = 14.67; range 10–20 years). Latent class analysis with the data of a computer-game preference scale revealed three types of players: “non-players”, “action-and-simulation game players” and “logic-and-skill-training game players”. Large gender differences were found with respect to class assignment. More females than males were found in the “logic-and-skill-training game player” class (82.9%) and in the class of “non-players” (81.9%). Males in contrast were overrepresented (81.7%) in the class of “action-and-simulation game players”. As expected, males on average outperformed females in mental-rotation test performance (d = 0.63). Furthermore, ANOVA results indicated mean differences in mental-rotation ability between action-and-simulation players and non-players (partial η² = .01) as well as age differences (partial η² = .04). With boys, non-players on average had lower MRT scores than action-and-simulation game players. For females, computer-game preference was unrelated to MRT performance. Results are discussed within a nature–nurture-interactionist framework of gender differences in spatial abilities.     

An own-age bias in age estimation of faces

IntroductionAge estimation performances may be influenced by group biases.ObjectiveThis study investigated whether we are more accurate at estimating the age of people from one's own-age than the age of younger or older people.MethodChildren, young and older adults’ performances at estimating both in-group and out-group faces were compared.ResultsA significant “Age of participants” × “Age of face stimuli” interaction was revealed. Moreover, the age of children's faces was more accurately estimated than the age of young and older adults’ faces by the three groups of participants.ConclusionThe present results revealed the occurrence of an own-age bias for children, young and older adults in age estimation. Several explanations to this own-age effect are discussed.     

Skepticism: Genuine unbelief or implicit beliefs in the supernatural?

We examined whether skeptics hold implicit supernatural beliefs or implicit cognitive underpinnings of the beliefs. In study 1 (N = 57), participants read a biological or a religious story about death. The story content had no effect on skeptics’ (or believers’) afterlife beliefs. Study 2 examined the relationships between religious and non-religious paranormal beliefs and implicit views about whether supernatural and religious phenomena are imaginary or real (n1 = 33, n2 = 31). The less supernatural beliefs were endorsed the easier it was to connect “supernatural” with “imaginary”. Study 3 (N = 63) investigated whether participants’ supernatural beliefs and ontological confusions differ between speeded and non-speeded response conditions. Only non-analytical skeptics’ ontological confusions increased in speeded conditions. The results indicate that skeptics overall do not hold implicit supernatural beliefs, but that non-analytically thinking skeptics may, under supporting conditions, be prone to biases that predispose to supernatural beliefs.     

Proportion dominance: The generality and variability of favoring relative savings over absolute savings

Four studies probe Ps’ sensitivity to absolute and relative savings. In three studies, Ps read scenarios forcing a tradeoff of saving more lives (230 vs. 225) vs. saving a larger proportion of a population (225 ÷ 230 = 75% vs. 230 ÷ 920 = 25%). Ps’ preferences were driven by both absolute and relative savings. Maximizing relative savings, called “proportion dominance” (PD), at the expense of absolute savings is non-normative, and most participants concur with this argument upon reflection (Studies 2 and 3). PD is related to individual differences, such that people scored as “rational” thinkers exhibited less PD than people scored as “experiential” thinkers (Studies 1 and 3). Finally, a fourth study extends these results, finding proportion dominance in other domains using a different paradigm. These four studies demonstrate both the generality (across domains and paradigms) and the variability (inter- and intra-individual) of proportion dominance.     

L'évaluation du burnout de Pines : adaptation et validation en version française de l'instrument Burnout Measure Short version (BMS-10)

The aim of this research present the psychometrics properties of a global measure of burnout. This study concern a framework of Pines and Aronson (1988). The aim of the study consist in testing the structure validity, a confirmatory factorial structure and a reliability of the BMS (“Burnout Measure Short version”). The results show that a confirmatory factor analysis and the temporal stability led to a BMS in French version (participants: N1 = 111; for reliability: N2 = 32). The unidimensional dimension of BMS was correlated with other measures (positively with “emotional exhaustion” [r = 0.53; p < 00] and negatively with “work satisfaction” [r = –0.19; p<0.02]). Practical implications are discussed.     

Variability of a “force signature” during windmill softball pitching and relationship between discrete force variables and pitch velocity

This study assessed reliability of discrete ground reaction force (GRF) variables over multiple pitching trials, investigated the relationships between discrete GRF variables and pitch velocity (PV) and assessed the variability of the “force signature” or continuous force-time curve during the pitching motion of windmill softball pitchers. Intraclass correlation coefficient (ICC) for all discrete variables was high (0.86–0.99) while the coefficient of variance (CV) was low (1.4–5.2%). Two discrete variables were significantly correlated to PV; second vertical peak force (r(5) = 0.81, p = 0.03) and time between peak forces (r(5) = −0.79; p = 0.03). High ICCs and low CVs support the reliability of discrete GRF and PV variables over multiple trials and significant correlations indicate there is a relationship between the ability to produce force and the timing of this force production with PV. The mean of all pitchers’ curve-average standard deviation of their continuous force-time curves demonstrated low variability (CV = 4.4%) indicating a repeatable and identifiable “force signature” pattern during this motion. As such, the continuous force-time curve in addition to discrete GRF variables should be examined in future research as a potential method to monitor or explain changes in pitching performance.     

Reasoning about knowledge: Children’s evaluations of generality and verifiability

In a series of experiments, we examined 3- to 8-year-old children’s (N = 223) and adults’ (N = 32) use of two properties of testimony to estimate a speaker’s knowledge: generality and verifiability. Participants were presented with a “Generic speaker” who made a series of 4 general claims about “pangolins” (a novel animal kind), and a “Specific speaker” who made a series of 4 specific claims about “this pangolin” as an individual. To investigate the role of verifiability, we systematically varied whether the claim referred to a perceptually-obvious feature visible in a picture (e.g., “has a pointy nose”) or a non-evident feature that was not visible (e.g., “sleeps in a hollow tree”). Three main findings emerged: (1) young children showed a pronounced reliance on verifiability that decreased with age. Three-year-old children were especially prone to credit knowledge to speakers who made verifiable claims, whereas 7- to 8-year-olds and adults credited knowledge to generic speakers regardless of whether the claims were verifiable; (2) children’s attributions of knowledge to generic speakers was not detectable until age 5, and only when those claims were also verifiable; (3) children often generalized speakers’ knowledge outside of the pangolin domain, indicating a belief that a person’s knowledge about pangolins likely extends to new facts. Findings indicate that young children may be inclined to doubt speakers who make claims they cannot verify themselves, as well as a developmentally increasing appreciation for speakers who make general claims.     

Étude de validation de la version française de l’Échelle d’Estime Corporelle (Body Esteem Scale) chez les adolescentes et les jeunes adultes

IntroductionThe literature of body image suggests that many women and young women suffer from body dissatisfaction and this dissatisfaction is an important risk factor for the development of eating disorders.ObjectiveThe aim of the study was to validate the French female version of the Body Esteem Scale (BES; Mendelson et al., 2001).MethodThis self-administered questionnaire assesses body esteem and includes three subscales: “Weight”, “Appearance” and “Attribution”. The questionnaire was given to a sample of 835 adolescent girls and young adults (mean age = 16.62 ± 1.50).ResultsExploratory factorial analysis yielded three factors “Weight”, “Appearance” and “Desire to modify and negative affect associated with the general appearance”, somewhat similar to those of the original validation study. The goodness-of-fit of the three factors model was satisfactory. Correlations were found between the three subscales of the BES, BMI and general self-esteem.ConclusionThe French version of the BES shows satisfactory psychometric properties and provides a useful tool for better understanding the psychological aspects of attitudes towards one's body. In France, very few questionnaires are available to measure body attitudes, despite the fact that the body dissatisfaction affects many adolescent girls and represents a risk factor for the development of eating disorders.     

Driving performance while using a mobile phone: A simulation study of Greek professional drivers

PurposeThe current study aims to assess the driving performance of professional drivers while using a mobile phone.Material and methodsA sample of 50 male professional drivers participated in the study. The sample was drawn conveniently from the professional drivers’ registries and the main taxi ranks. The inclusion criteria were: (a) age above 18 years, (b) possession of a driving license, (c) sufficient reading, writing, and communicating skills, (d) informed consent prior to participation. Laboratory tests were conducted using the VS500M driving simulator manufactured by Virage Simulation Inc. The intervention involved different tasks/assignments: (a) driving without using a mobile phone (Control time), (b) driving while having a conversation on the mobile phone, (Task_1), (c) driving while reading out loud text messages (Task_2) and, (d) driving while texting (Task_3). Differences in the driving performance between the control time and the time with assignments, were examined. The participants were evaluated on the followings outcome measures: (a) variation of the steering position per second, (b) following distance per second, (c) variation of the lateral lane position per second, and (d) sum of squared acceleration per second.ResultsThe analysis indicated that “variation of the steering position per second” was significantly affected by “text-message reading” [t(50) = −5.443; p < 0.0001] and “texting” [t(50) = −5.442; p < 0.0001]. A significant main effect was observed in terms of the “following distance per second” and the “variation of the lateral lane position per second” for all the three mobile phone assignments. Lastly, the “sum of squared acceleration per second” was significantly decreased during conversation on the phone [t(50) = 2.713; p = 0.009] as well as during texting [t(50) = 3.428; p = 0.001] as compared with the control time.ConclusionsThe study is among the few existing experimental studies in a country with one of the highest road fatalities in Europe but with limited evidence on road traffic behaviour. This study could guide the design of large-scale simulation studies aiming to explore the impact of mobile phone on driving behaviour.     

Embodied image: Gender differences in functional and aesthetic body image among Australian adolescents

Perceptions of the body are not restricted to the way the body “looks”; they may also extend to the way the body “functions”. This research explores body image among male and female adolescents using the Embodied Image Scale (EIS), which incorporates body function into body image. Adolescents (N = 1526, male = 673, female = 853) aged 12–17 (M = 13.83, SD = 1.02), from 26 Western Australian high schools were surveyed. Information was gathered on pubertal timing, body mass index (BMI) and body image. Participants reported significantly higher value of, behavioral-investment in, and satisfaction with the functional dimension of the body compared to the aesthetic dimension. After controlling for age, pubertal timing, and BMI, females reported significantly higher aesthetic values and aesthetic behavioral-investment, and lower aesthetic satisfaction, functional values, functional behavioral-investment and functional satisfaction than male participants. Grade, pubertal timing and BMI category differences were also explored.     

One-year neurodevelopmental outcome of very and late preterm infants: Risk factors and correlation with maternal stress

Although “late preterm” (LP) newborns (33–36 weeks of gestational age) represent more than 70% of all preterm labors, little is known about the relation between certain risk factors and developmental outcomes in LP compared to “very preterm” (≤32 weeks) children (VP).This study investigates: (1) LP and VP infants’ development at 12 months of corrected age (CA) using the Bayley Scales of Infant Development – 3rd Edition (BSID-III); (2) correlation between BSID-III performances and maternal stress (using Parenting Stress Index-Short Form, PSI-SF) among LP and VP at 12 months CA; and (3) the link between known neonatal and demographic risk factors and developmental outcomes of LP and VP infants.For both LP and VP infants the Mean Cognitive (LP: 102.69 ± 7.68; VP: 103.63 ± 10.68), Language (LP: 96.23 ± 10.08; VP: 99.10 ± 10.37) and Motor (LP: 91.11 ± 10.33; VP: 93.85 ± 10.17) composite scores were in the normal range, without significant differences between the groups. Correlations between PSI-SF and BSID-III showed that in the VP group (but not LP), Language score was negatively related to the PSI-SF ‘Difficult Child’ scale (r = −.34, p < .05). Regression models revealed that cognitive performance was significantly predicted by physical therapy in LP and by cesarean section in VP infants. For VP only maternal education and length of stay predicted Language score, whereas physical therapy predicted Motor score.Results of the study underline the importance of considering cognitive, language and motor developments separately when assessing a preterm child's development. Prediction models of developmental performance confirm the influence of some known neonatal risk factors and indicate the need for further research on the role of sociodemographic risk factors.
