Effect of peer presence on adolescents' risk-taking is moderated by individual self-esteem: An experimental study

Prior research suggests that the presence of peers increases adolescents' risk-taking. However, it is not clear whether the effect of peer presence is moderated by individual characteristics such as self-esteem, since individuals with low self-esteem are more susceptible to peer influence theoretically. The present study examined this problem using an adapted Stoplight Game in an experiment. A final sample of 140 adolescent students aged 14–18 (M = 16.25 ± 0.73 years, 61 girls), divided into two groups—low self-esteem and high self-esteem, according to their self-esteem scores, completed a risk-taking task either alone or in the presence of a same-sex peer. The results indicated that peer presence increased adolescents' risk-taking, specifically for those with low self-esteem, while those with high self-esteem were not affected by peer presence. The findings are helpful for our understanding of peer influence on adolescent risk-taking and the moderating role of the self and have practical implications for preventing and intervening adolescents' risk-taking via increasing their self-esteem.     

Not only assholes drive Mercedes. Besides disagreeable men,also conscientious people drive high-status cars

In a representative sample of Finnish car owners (N = 1892) we connected the Five-Factor Model personality dimensions to driving a high-status car. Regardless of whether income was included in the logistic model, disagreeable men and conscientious people in general were particularly likely to drive high-status cars. The results regarding agreeableness are consistent with prior work that has argued for the role of narcissism in status consumption. Regarding conscientiousness, the results can be interpreted from the perspective of self-congruity theory, according to which consumers purchase brands that best reflect their actual or ideal personalities. An important implication is that the association between driving a high-status car and unethical driving behaviour may not, as is commonly argued, be due to the corruptive effects of wealth. Rather, certain personality traits, such as low agreeableness, may be associated with both unethical driving behaviour and with driving a high-status car.     

Regression I. Experimental approaches to regression

The concept of regression is considered with an emphasis on the differences between the positions of Freud and Jung regarding its significance. The paper discusses the results of experimental analyses of individual experience dynamics (from gene expression changes and impulse neuronal activity in animals to prosocial behaviour in healthy humans at different ages, and humans in chronic pain) in those situations where regression occurs: stress, disease, learning, highly emotional states and alcohol intoxication. Common mechanisms of regression in all these situations are proposed. The mechanisms of regression can be described as reversible dedifferentiation, which is understood as a relative increase of the representation of low-differentiated (older) systems in the actualized experience. In all of the cases of dedifferentiation mentioned above, the complexity of the systemic organization of behaviour significantly decreases.     

Pathways to behavior problems in Norwegian kindergarten children: The role of parent emotion socialization and child emotion understanding

More than two decades of research have shown that parental emotion-related socialization behaviors (ERSBs) significantly predict child emotion understanding and externalizing behavior problems. This study aimed to replicate these findings in a sample of 40 Norwegian preschool children and to test whether the effect of parental ERSBs on externalizing child behavior problems was mediated through child emotion understanding. Parental report on ERSBs was obtained using the Coping with Children’s Negative Emotions Scale (CCNES) questionnaire. Child emotion understanding was assessed directly using the Test of Emotion Comprehension (TEC). The results showed that parental distress reactions and externalizing child behavior problems were significantly correlated and that parental expressive encouragement was significantly correlated with child emotion understanding. Estimation of indirect effects was conducted using process analysis and showed that parental expressive encouragement was indirectly related to externalizing child behavior problems (b = −0.17) via child emotion understanding. The results suggest that better child emotion understanding, and lower parental distress are related to lower levels of behavior problems in preschool children. These findings provide support for the Parental Meta-Emotion Philosophy (PMEP) model, where the effect of parental emotion socialization on externalizing child behavior problems is mediated through emotion understanding.     

Spontaneous imagined contact and intergroup relations: Quality matters

While research on experimental interventions that aim to improve outgroup attitudes via contact imagery grows, it is important to examine if contact imagery that occurs in spontaneous, non-experimentally controlled conditions drives attitudes, and in what direction. To answer this, we constructed and validated a spontaneous imagined intergroup contact scale (SIICS) that differentiates between frequency, quality and elaboration of the spontaneous imagery of outgroups. In three correlational studies (N_Portugal = 305, N_{United Kingdom} = 185, N_Italy = 276), we tested the role of spontaneous imagined contact frequency, quality and elaboration in predicting attitudes and social distance (Studies 1–3) and intended behaviour (Study 3) toward immigrant groups. Results demonstrated that spontaneous imagined contact quality consistently predicted key outcome variables above and beyond the other two dimensions. Importantly, the effects were significant while controlling for other potent forms of direct and indirect contact. Implications of the findings for theory and practice are discussed.

Investigating the social environment of the A‐not‐B search task

Controversy exists concerning the origins of object permanence, with different measures suggesting different conclusions. Looking measures have been interpreted as evidence for early understanding (Baillargeon, 1987, Developmental Psychology, 23 :655), while Piaget (The construction of reality in the child, 1954) interpreted perseverative reaching behaviour on his AB search task to be indicative of limited understanding. However, looking measures are often reported to be an unreliable index of infant expectation (Haith, 1998, Infant Behaviour and Development, 21 :167) and reaching behaviour has been explained by many alternative processes (e.g. Smith et al., 1999, Psychological Review, 106 :235; Topál et al., 2008, Science, 321 :1831). We aimed to investigate whether social looking (Dunn & Bremner, 2017, Developmental Science, 20 :e12452; Walden et al., 2007, Developmental Science, 10 :654) can be used as a valid measure of infant expectation of object location during the Piagetian AB search task. Furthermore, we aimed to test the social accounts of perseverative reaching by investigating how the direction of experimenter gaze would affect infant search and social behaviour. Infant search and social behaviour was compared on B trials across three different conditions, namely experimenter gaze to midline, location A and location B. Search performance significantly improved when the experimenter looked to location B. Infant social looking indicated that infants expect the object to be found in the location in which they search and are actively seeking information about object location from the experimenter. We conclude that social looking is a valid index of infant expectation that has provided support for the importance of the social environment on the AB search task. This casts doubt on the potential for this task to provide information related to the development of object permanence in infancy.     

Characterising mobile phone calls while driving on limited-access roads based on SHRP 2 naturalistic driving data

Research has found that mobile phone call engagement while driving negatively affects driving performance. However, no studies exist characterising hand-held mobile phone calls while driving under naturalistic conditions that include aspects such as the duration of mobile phone subtasks and glance behaviour. Identifying the particularly distracting phases of hand-held telephoning and the nature of influencing factors are the basis for developing design recommendations (e.g. for an in-vehicle information system). Potential influencing factors on driving performance such as call type, mobile phone storage location, or any self-regulatory behaviour need to be taken into account. The present study aimed to draw a comprehensive picture of making hand-held mobile phone calls while driving on limited-access roads using SHRP 2 naturalistic driving data. Mobile phone phase duration, glance behaviour, call type, and mobile phone storage location were coded manually across 98 events. The results show that the handling phase of a mobile phone call (e.g. searching for contacts, dialling) was the most dangerous due to longer mean off- than on-road glances. Outgoing calls caused longer mean off-road glances than incoming; nevertheless, the 2 s critical threshold was not exceeded. A significant influence of mobile phone storage location on glance behaviour did not exist. Moreover, at least in free-flow driving conditions, drivers had enough spare capacity to conduct a mobile phone call without reducing vehicle speed. The results suggest that in low complexity traffic situations drivers can compensate for the increased driving task demand due to telephoning by making minor changes in glance behaviour.     

A comparison of computational driver models using naturalistic and test-track data from cyclist-overtaking manoeuvres

The improvement of advanced driver assistance systems (ADAS) and their safety assessment rely on the understanding of scenario-dependent driving behaviours, such as steering to avoid collisions.This study compares driver models that predict when a driver starts steering away to overtake a cyclist on rural roads. The comparison is among four models: a threshold model, an accumulator model, and two models inspired by a proportional-integral and proportional-integral-derivative controller. These models were tested and cross-applied using two different datasets: one from a naturalistic driving (ND) study and one from a test-track (TT) experiment. Two perceptual variables, expansion rate (the horizontal angular expansion rate of the image of the lead road user on the driver’s retina) and inverse tau (the ratio between the image’s expansion rate and its horizontal optical size), were tested as input to the models. A linear cost function is proposed that can obtain the optimal parameters of the models by computationally efficient linear programming.The results show that the models based on inverse tau fitted the data better than the models that included expansion rate. In general, the models fitted the ND data reasonably well, but not as well the TT data. For the ND data, the models including an accumulative component outperformed the threshold model. For the TT data, due to the poorer fit of the models, more analysis is required to determine the merit of the models. The models fitted to TT data captured the overall pattern of steering onsets in the ND data rather well, but with a persistent bias, probably due to the drivers employing a more cautious strategy in TT.The models compared in this paper may support the virtual safety assessment of ADAS so that driver behaviour may be considered in the design and evaluation of new safety systems.     

Stereotypical behavioural cues — but not their order — influence credibility judgements

To what extent stereotypical deceptive behaviours such as gaze aversion and fidgeting actually influence people's credibility judgements remain largely unknown. In this study, we directly manipulated the presence/absence of such behaviours to investigate this. Participants were shown four truthful videos in which we manipulated the presence of stereotypical cues and asked them to judge how credible the person in each video is. Moreover, research consistently shows that decision making is influenced by various cognitive biases. One example is the primacy effect, which implies that people form an opinion early in the decision process. Information acquired early will have the largest influence on how subsequent information will be interpreted. To investigate a possible primacy effect, we also manipulated whether these cues were present towards the beginning or the end of the video (i.e. the timing of the manipulation). In line with our expectations, the presence of stereotypical cues significantly lowered the observed credibility, showing that the presence of these cues indeed influences credibility judgements. The timing of the cues had no effect.
