How Collusion Perpetuates Racial Discrimination in Societies that Ostensibly Promote Equal Opportunity

It is shown here that injustices due to racial discrimination are best identified in light of the deleterious effects they have upon their victims, rather than the beliefs and attitudes of their perpetrators. For among participants who cooperate clandestinely to bring about racial injustice there may be broad disagreement about what it is they are doing collectively, and why; or they may disagree in principle about whether what they are doing is morally right. I employ the notion of ‘nomotropic’ behaviour to replace the oversimplified notion of ‘rule-following’ in order to explain how duplicity and hypocrisy fall shy of being regarded as irrational in social climates where implicit norms reinforce racial privileging while explicit norms denounce it. Further, examining the ‘collective utility’ of dogmatic beliefs and norms comprising part of the social architecture that covertly reinforces racial injustice (while ostensibly deriding it) may help to explain why it often seems to make so little difference whether members of an unfairly advantaged elite, whose collaborative behaviour perpetuates a social injustice, individually approve of doing so or not.     

Implied motion produces real depth

Static images taken from an animation of continuous motion, such as a photograph of a figure in a running pose, contain no real motion (RM) information. Interestingly, while imaging studies have shown that passively viewing these implied motion (IM) stimuli activate the same brain regions as RM, the perceptual effects of adding IM to RM are not fully understood. Given that IM appears to recruit the same neural mechanisms as RM, it should be possible to capitalize on this functional overlap and use IM in addition to, or in place of, RM to influence the perception of depth from motion parallax (MP). In the current study, we found that IM influenced depth-sign judgments as expected based on the geometry of MP with RM. These results bolster our understanding of the neural mechanisms of both IM and MP by demonstrating that IM coupled with pursuit eye movements generates unambiguous depth from MP.     

Maternal distress during pregnancy and language development in preschool age: A population-based cohort study

Recent studies have emphasized the importance of the prenatal period for children's cognitive development. Prenatal exposure to psychological distress has been identified as one potential agent affecting neurodevelopment, although research in this area has been marked by some contradictory findings and methodological limitations. This study aimed to investigate the effect of maternal distress during pregnancy on language development of preschool children. This study was based on the Norwegian Mother and Child Cohort Study conducted at the Norwegian Institute of Public Health. The sample was composed of 34,089 women and their children. We assessed the role of maternal prenatal distress on child language over and above that of premature low birth weight (PLBW) status and postnatal maternal distress. Fear of giving birth had a negative impact on language outcome at age three over and above the effect of PLBW status and postnatal maternal distress. However, this effect was of minimal magnitude. Moreover, when examining whether differences in language skills between siblings were associated with differences in experienced levels of prenatal stress across pregnancies (sibling fixed-effects models), no significant effects were found. Our study suggests that prenatal distress within moderate limits does not seem to have an independent impact on child language performance in the preschool years and emphasizes the importance of considering the contextual role played by more stable maternal and family characteristics.     

Early motor development and cognitive abilities among Mexican preschoolers

Psychomotricity plays a very important role in children’s development, especially for learning involving reading–writing and mathematical calculations. Evaluate motor development in children 3 years old and its relationship with their cognitive abilities at the age of 5 years. Based on a cohort study, we analyzed the information about motor performance evaluated at 3 years old by Peabody Motor Scale and cognitive abilities at 5 years old. The association was estimated using linear regression models adjusted by mother’s intelligence quotient, sex, Bayley mental development index at 18 months, and quality of the environment at home (HOME scale). 148 children whose motor performance was determined at age 3 and was evaluated later at age 5 to determine their cognitive abilities. Cognitive abilities (verbal, quantitative, and memory) measured by McCarthy Scales. Significant positive associations were observed between stationary balance at age 3 with verbal abilities (β = 0.67, p = .04) and memory (β = 0.81, p = .02) at 5 years. Grasping and visual-motor integration were significant and positively associated with quantitative abilities (β = 0.74, p = .005; β = 0.61, p = .01) and memory (β = 2.11, p = .001; β = 1.74, p = .004). The results suggest that early motor performance contributes to the establishment of cognitive abilities at 5 years. Evaluation and early motor stimulation before the child is faced with formal learning likely helps to create neuronal networks that facilitate the acquisition of academic knowledge.

The emotional impact of bullying and cyberbullying on victims: a European cross-national study

Past research has demonstrated the effects of bullying can be severe and long term for the individuals involved. The main aim of this study is to analyze the emotional impact on victims of traditional bullying, both direct and indirect forms, and of cyberbullying through mobile phones and the Internet. A sample of 5,862 adolescents from three different countries, Italy (N = 1,964), Spain (N = 1,671), and England (N = 2,227), responded to a questionnaire that asked if they had experience of various forms of bullying, and the consequent emotional impact. The results show that both traditional bullying and cyberbullying have a significant prevalence in the samples. Emotional responses are linked to types of bullying. Analysis of answers identified specific emotional profiles for the different types of bullying and cyberbullying. Direct bullying and cyberbullying via mobile phone showed similar profiles, and also indirect bullying and cyberbullying using the Internet. Similarities and differences between profiles are discussed and some hypotheses are presented to explain the results. In addition, school grade, gender, country, and severity of bullying episodes were related to the specific emotional profiles of each type of bullying. Aggr.

Exploiting illusory effects to disclose similarities in numerical and luminance processing

Recent studies have suggested that numerical and physical magnitudes are similarly processed by a generalized magnitude system. The present study investigates the number?Cluminance interaction, taking advantage of illusory effects in a cued line bisection task with numerical or nonnumerical flankers and varying levels of luminance. The results showed that both dimensions influenced bisection performance. Whereas numbers (Experiment 1) induced a systematic shift of the subjective midpoint toward the larger digit, luminance (Experiment 2) modulated the bisection performance toward the darker flanker. By combining these two illusions (Experiments 3 and 4), the two dimensions interfered with each other. This pattern of results suggests overlapping representations for physical and numerical magnitudes and highlights the value of illusory effects in cognitive research.     

The Peer Informant: Characteristics Related to the Perceptions of Peer Behavior Problems

Victimization and rejection by peers leads to and exacerbates behavior problems in children and adolescents. Given the implications of problematic peer relations for adolescents who experience behavior problems, the present study examined factors that may be related to how adolescents perceive peers who exhibit such problems. Specifically, the present study examined the relationship of adolescent informants’ socioeconomic status, their prior exposure to psychological symptoms, their perceived social acceptance, and their own behavior problems to their perceptions of peers’ internalizing and externalizing behavior problems, their liking and disliking of peers who exhibit such problems, and their attributions for the etiology of such problems when portrayed by fictitious peers of the same age. In particular, adolescents were asked to rate a set of vignettes portraying internalizing and externalizing behavior problems that are seen commonly in peers and to complete a set of brief questionnaires. Results revealed that adolescents were able to perceive the presence of both internalizing and externalizing behavior problems in vignette characters. Additionally, vignette characters who did not exhibit behavior problems were most likely to be approached and liked, whereas those vignette characters who displayed externalizing behavior problems were more likely to be disliked and ignored. Finally, although adolescents endorsed both internal and external etiological factors, ratings were related to the sex of the depicted vignette character and the nature of the portrayed behavior problems. Overall, this study provided additional evidence that, although adolescents can serve as valuable informants, they also tended to be rejecting of peers who display behavior problems.
