Elimination of the enhanced Simon effect for older adults in a three-choice situation: Ageing and the Simon effect in a go/no-go Simon task

In a Simon task, participants show better performance when the irrelevant stimulus location corresponds with the response location than when it does not, and this effect is typically greater for older adults than for younger adults. To study the effect of cognitive ageing in the Simon task, we compared young and old adults using two versions of the Simon task: (a) a standard visual Simon task, for which participants respond with left and right key-presses to the red and green colours of stimuli presented in left and right locations; (b) a go/no-go version of the Simon task, which was basically the same, except that the shape of the stimulus in one third of the trials indicates that no response is to be made. In both tasks, both age groups showed the Simon effect. The magnitude of the effect for the standard Simon task was greater for the older adults than for the younger adults. Nevertheless, the two groups showed an equivalent Simon effect in the go/no-go version of the Simon task. Reaction time distribution analyses revealed basically similar functions for both age groups: a decreasing pattern of the Simon effect in the standard task and an increasing pattern of the effect in the go/no-go version of the task. The results suggest that older adults find it more difficult to suppress an automatic activation of the corresponding response, though this automatic activation was reduced in situations where the response was frequently inhibited.     

Atmosphere in an urban nightlife setting: A case study of the relationship between the socio‐physical context and aggressive behavior

Aggression is strongly influenced by the surrounding socio‐physical context, and the development of aggressive behavior is best understood through a continuous cycle of ongoing person‐environment interactions. Empirical studies, nevertheless, have been predominantly conducted in the laboratory, studying aggression as a short‐lived phenomenon, emerging from and within an individual, and – with situational factors studied in isolation – devoid of its context. The present field study, conducted in an urban nightlife area, complements this research. A qualitative, multi‐method approach was followed by thematic analysis to investigate ongoing behavioral patterns of the crowd vis‐à‐vis the changes in the context that co‐occurred with the development of unwanted behaviors, including aggression. In our study, we identified atmosphere as a dynamic and mood‐like, but extra‐individual state of the socio‐physical setting related to the development of aggression. Our results suggest that atmosphere affects the behavior of groups and individuals by emerging from and feeding into ongoing interactions between people and the environment. At the individual level, it appears to play its part as proximate determinant of behavior; at the crowd level it reflects the synergetic product of all those persons’ states, behaviors and interactions. Implications for aggression theory and for applications aimed at curbing aggression are discussed.     

Androgen dynamics in the context of children's peer relations: an examination of the links between testosterone and peer victimization

Testosterone levels have been shown to decrease in the face of social defeat in several mammalian species. Among humans, the loss of social status has been studied primarily in the context of athletic competition, with winners having higher testosterone levels than losers. This study examined testosterone levels in relation to peer victimization (bullying) in a sample of 151 boys and girls aged 12–13. Statistically controlling for age and pubertal status, results indicated that on average verbally bullied girls produced less testosterone and verbally bullied boys produced more testosterone than their nonbullied counterparts. Similar trends were evident comparing social and physical bullying with testosterone. Sex differences are discussed in terms of empirically validated differences in coping styles, as girls tend to internalize, whereas boys tend to externalize, their abuse. Aggr.

Stability of choices in a risky decision‐making task: a 3‐year longitudinal study with children and adults

In a 3‐year follow‐up to Levin and Hart's ( 2003 ) study, we observed the same children, now 9–11 years old, and their parents in the same risky decision‐making task. At the aggregate level the same pattern of means was observed across time periods. At the individual level the key variables were significantly correlated across time periods for both children and adults. Taken together with the results from the original study and earlier studies, these results solidify the following conclusions: children utilize both probability and outcome information in risky decision‐making; the tendency to make more risky choices to avoid a loss than to achieve a gain of equal magnitude, which is a major tenet of the leading theories of risky decision‐making, occurs for children as well as adults; children make more risky choices than adults; temperamental predictors of risky choice are valid for children as well as for adults.

A comparison of fathers' and mothers' contributions in the prediction of academic performance of school-age children in Hong Kong

Asystematic study of the linkages between gender issues and parenting is made among Chinese families. This study examines sex differences in parenting attributes across fathers and mothers and towards sons and daughters, and compares the contributions of fathers and mothers to the prediction of academic performance across boys and girls. Four parenting attributes are included: nurturance, psychological control, parental involvement in education, and parental academic efficacy. Data were collected from 461 Chinese father-mother-child triads of children studying Grade 3 to 5 in Hong Kong. Findings of this study, based on multivariate analysis of variance, showed that parental roles followed traditional Chinese cultural expectations. Compared to the fathers, Chinese mothers of school-age children in Hong Kong were more loving and caring, more involved in children's education, and more efficacious in promoting children's academic performance. Results of hierarchical regression analysis examining the role of child's sex as a moderator showed cross-sex influence in parental contribution to academic performance with respect to parental psychological control and academic efficacy. Specifically, boys benefited more from maternal efficacy than girls did and they were also more hampered by mothers with high psychological control, while girls' academic performance was more enhanced by paternal academic efficacy than boys. A gender-balance approach that highlights the significance of gender in moderating parental contributions to academic performance was thus supported. Future research should continue to focus on psychological control and domain-specific parental attributes as potential sources of gender-linked parent-child associations. Investigations should also explore other cognitive and noncognitive domains of child outcome, different child age groups, as well as Chinese populations in various geographical regions.     

Binge drinking and violence against dating partners: the mediating effect of antisocial traits and behaviors in a multinational perspective

Research has consistently shown a link between alcohol use and partner violence (PV). Little is known concerning the strength of this association across cultures and genders, and few have assessed possible mediators. This study assesses the link between binge drinking and PV among 7,921 college students in 38 sites around the world, and investigates the mediating role of antisocial traits and behaviors (ASTB). A significant association was found between binge drinking and PV, the strength of which differed by site but not by gender. ASTB fully mediated this association. The mean level of binge drinking at each site did not significantly influence the strength of the association between binge drinking and PV.     

Functional magnetic resonance imaging study of Piaget's conservation-of-number task in preschool and school-age children: a neo-Piagetian approach

Jean Piaget’s theory is a central reference point in the study of logico-mathematical development in children. One of the most famous Piagetian tasks is number conservation. Failures and successes in this task reveal two fundamental stages in children’s thinking and judgment, shifting at approximately 7 years of age from visuospatial intuition to number conservation. In the current study, preschool children (nonconservers, 5-6 years of age) and school-age children (conservers, 9-10 years of age) were presented with Piaget’s conservation-of-number task and monitored by functional magnetic resonance imaging (fMRI). The cognitive change allowing children to access conservation was shown to be related to the neural contribution of a bilateral parietofrontal network involved in numerical and executive functions. These fMRI results highlight how the behavioral and cognitive stages Piaget formulated during the 20th century manifest in the brain with age.     

Living in a multicultural world: Intergroup ideologies and the societal context of intergroup relations

In a relatively short time span, issues of ethnic, cultural, and religious diversity have become central topics of discussion in various nations. As a result, the role of broad ideologies that frame and structure relations between groups has received increasing attention by social psychologists. Of particular concern has been the role of these intergroup ideologies in promoting intergroup harmony and reducing prejudice. In this article, we appraise the evidence related to three main intergroup ideologies, assimilation, colourblindness, and multiculturalism. We argue that research in this area has paid insufficient attention to the social and political context. Intergroup ideologies have been studied and conceptualised as being located solely within individual minds. We suggest that the potentially vital aspect of these ideologies is that they are sometimes widely shared by members of a social group. Integrating sociological and political analyses, we discuss the fact that intergroup ideologies are institutionalised as policies and that, as such, they often vary across countries and across time. We present a series of studies to illustrate the theoretical implications of studying the shared nature of these intergroup ideologies, providing insights into the question of when and why national policies can shape individuals’ intergroup attitudes and beliefs and improve intergroup relations.     

Predictors of volitional personality change in younger and older adults: Response surface analyses signify the complementary perspectives of the self and knowledgeable others

Goals to change personality traits have been linked to self-rated Big Five traits. Extending previous research, we investigated the associations between change goals and diverse personality characteristics (e.g., self-esteem), other-rated Big Five traits, and self-other agreement in an age-heterogeneous sample (N = 378). Results replicated previous associations of change goals with age and self-rated traits. Additionally, change goals were stronger when others rated a person’s traits as low and when self-other agreement about traits was greater for extraversion, agreeableness, and conscientiousness. Associations of additional personality characteristics with change goals diminished when we controlled for the Big Five traits. We conclude that goals to change personality traits primarily reflect the perspective of the self and, for some traits, of knowledgeable others.     

The clocks that time us are not the same: A theory of temporal diversity,task characteristics,and performance in teams

Temporal individual differences are an under-explored, but research-worthy form of diversity in teams. Although persistent differences in how members think about and value time can profoundly influence team performance, the compositional impact of time-based individual differences is regularly overlooked. Optimal or suboptimal team performance can result because the composition of time-based individual differences is matched or unmatched (respectively) to task demands. Therefore, we offer a detailed presentation of how the configuration of four time-based individual differences (time urgency, time perspective, polychronicity, and pacing style) interact with two task typologies (task type and task complexity) to specify when elevation (mean) and diversity (dispersion) of temporal differences is helpful or harmful to team performance.     

Automatic thoughts as a predictor of internalizing and externalizing problems in Chinese adolescents: A test of the cognitive content‐specificity hypothesis with age effects

The main aim of the current study was to test the cognitive content‐specificity hypothesis across internalizing and externalizing problems in Chinese adolescents. The participants consisted of 2,158 adolescents aged 11–19 years from three middle schools, and they completed a number of measures assessing a wide range of automatic thoughts and syndromes related to internalizing and externalizing problems. Multivariate regression analyses demonstrated that thoughts about social threats, personal failure and hostility were the strongest predictors of anxiety, depression, and externalizing problems, respectively. Age was a statistically significant, albeit modest, moderator of the relationship between automatic thoughts about social threat and anxiety. The current study provides support for the cognitive content‐specificity hypothesis in internalizing and externalizing problems in a Chinese sample.     

The effect of labour on ownership decisions in two cultures: Developmental evidence from Japan and the United Kingdom

Creative labour has an effect on children's and adults' ownership decisions in Western cultures. We investigated whether preschoolers and adults from an Eastern culture (Japan) would show a similar bias. In a first‐party task (Experiment 1), in which participants created their own objects, Japanese preschoolers but not adults assigned ownership to creators. When participants watched videos of third‐party conflicts between owners of materials and creators (Experiment 2), Japanese adults, but not preschoolers, transferred ownership to creators. In a British comparison group, both preschoolers and adults showed an effect of creative labour in the third‐party task. A bias to attribute ownership on the basis of creative labour is thus not specific to Western culture.     

Perception and action in a far-aiming task: Inhibition demands and the functionality of the Quiet Eye in motor performance

It is incontestable that high motor performance requires an optimal coupling between perception and action. In sports as well as in professional tasks, the Quiet Eye (QE) – defined as the final fixation before movement initiation – has been found to explain a considerable amount of variance in motor performance and expertise. In the current series of studies, the underlying mechanisms of this perception-action variable were further investigated by testing predictions of the inhibition hypothesis. According to the inhibition hypothesis, the functionality of the QE is to shield movement parametrization. By manipulating the demands during response selection (Experiment 1 and Experiment 2) and movement control (Experiment 2) in a far-aiming task, it was found that – in line with the predictions – QE duration increased with increasing inhibition demands. This effect was mainly driven by the similarity rather than the number of possible actions. Moreover, the relation between inhibition demands and QE-duration were sustained through both response selection and movement control, which is perfectly in line with the notion of a continuous perception-action cycle in motor behavior. In sum, these findings corroborate the inhibition function as an integral component within a cognitive understanding of the QE phenomenon.
