Social Judgments and Emotion Attributions About Exclusion in Switzerland
Adolescents' social judgments and emotion attributions about exclusion in three contexts, nationality, gender, and personality, were measured in a sample of 12-and 15-year-old Swiss and non-Swiss adolescents (N = 247). Overall, adolescents judged exclusion based on nationality as less acceptable than exclusion based on gender or personality. Non-Swiss participants, however, who reflected newly immigrated children to Switzerland, viewed exclusion based on nationality as more wrong than did Swiss participants and attributed more positive emotions to the excluder than did Swiss participants. Girls viewed exclusion in nationality and personality contexts as less legitimate than did boys, and they attributed less positive emotions to excluder target in the nationality context than did boys. The findings extend existing research on exclusion by focusing on both emotion attributions as well as judgments and by investigating exclusion in a sample that included a recent immigrant group.

Understanding of Goals, Beliefs, and Desires Predicts Morally Relevant Theory of Mind: A Longitudinal Investigation
Developmental continuity between infants' understanding of intentional agency (goals, beliefs, and desires) and young children's attributions of moral intentions were studied in a 4-year longitudinal study (N = 77 children). First, goal encoding at the age of 7 months and implicit false belief understanding at 18 months were predictive of children's understanding of an accidental transgressor's moral intentions at the age of 5 years. Second, 24-month-olds' understanding of subjective desires was predictive of children's ability to understand an accidental transgressor's false belief at 5 years. These correlations remained significant when controlling for gender and verbal IQ. These findings support the theory that an early understanding of intentional agency is foundational for moral cognition in childhood.

A Developmental Neuroscience Study of Moral Decision Making Regarding Resource Allocation
Distinguishing between equity and equality is essential when making social and moral decisions, yet the related neurodevelopmental processes are unknown. Evaluations of contextually based third-party distributions incorporating recipient need and resource importance were examined in children and adolescents (N = 82; 8-16 years). Spatiotemporal neurodynamic responses show distinct developmental profiles to viewing such distributions. Event-related potentials (ERPs) differentially predicted real-life behaviors based on age, where older children's (8-10 years) evaluations were related to a fairly rapid, automatic ERP component (early posterior negativity), whereas adolescent and preadolescent (11-16 years) evaluations, first-person allocations, and prosocial behaviors were predicted by later, cognitively controlled ERP components (P3 and late positive potential). Together, these results reveal age-related changes regarding the neural responses that correspond to distributive justice decisions.

Teacher evaluations of interethnic bullying of an Arab student: The role of perceiving refugees as a threat or benefit
Interethnic bullying that targets ethnic minority students has serious consequences for the lives of victimized students. Teachers’ evaluations of the bullying are critical because teacher intervention can stop bullying and improve the adjustment of victimized students. Because the literature has documented partially overlapping biases against people of Arab ethnicity and people with refugee backgrounds, this study investigated whether teachers’ attitudes toward refugees play a role in their evaluations of the interethnic bullying of an Arab student. Teachers (
n
= 373; 77% female) who participated in the study filled the Threats–Benefits Inventory (TBI) that measured two types of attitudes toward refugees (perceiving refugees as a threat and perceiving refugees as a benefit) and evaluated a hypothetical vignette of interethnic bullying targeted at an Arab student. SEM analysis, controlling for gender, age, and contact with refugees, indicated that teachers’ attitudes toward refugees were not associated with their perceptions of the interethnic bullying as wrong or with their willingness to intervene. However, viewing refugees as a source of high threat or low benefit was consistently associated with lower recognition of the negative outcomes of the interethnic bullying. Moreover, a greater willingness to intervene positively associated with female gender and increasing age. The study suggests that teachers’ attitudes toward refugees may contribute to underestimating negative outcomes of interethnic bullying among students. To foster appropriate evaluations of interethnic bullying, teacher education should aim to promote understanding of different marginalized groups and to reduce biases against people with refugee backgrounds.

Children's Social Reasoning about Inclusion and Exclusion in Gender and Race Peer Group Contexts
This study investigated whether children's and adolescents' judgments about exclusion of peers from peer group activities on the basis of their gender and race would differ by both age level and the context in which the exclusion occurred. Individual interviews about exclusion in several different contexts were conducted with 130 middle-class, European American children and adolescents. Younger children were expected to reject exclusion, by using judgments based on moral reasoning, regardless of the potential cost to group functioning, whereas older children were expected to condone exclusion on the basis of group membership in cases in which the inclusion of these children might interrupt effective group functioning. On measures of judgments, justifications for those judgments, and ratings of the appropriateness of exclusion, the vast majority of children used moral reasoning and rejected exclusion in contexts in which only the presence of a stereotype justified it. As expected, however, older children (13 years) were more likely to allow exclusion than younger children (7 and 10 years) when group functioning was threatened, and they justified this exclusion by using appeals to effective group functioning.

Effect of High Intensity Interval Training Compared to Continuous Training on Cognitive Performance in Young Healthy Adults: A Pilot Study
To improve cognitive function, moving the body is strongly recommended; however, evidence regarding the proper training modality is still lacking. The purpose of this study was therefore to assess the effects of high intensity interval training (HIIT) compared to moderate intensity continuous exercise (MICE), representing the same total training load, on improving cognitive function in healthy adults. It was hypothesized that after 6 weeks (3 days/week) of stationary bike training, HIIT would improve executive functions more than MICE. Twenty-five participants exercised three times a week for 6 weeks after randomization to the HIIT or MICE training groups. Target intensity was 60% of peak power output (PPO) in the MICE group and 100% PPO in the HIIT group. After training, PPO significantly increased in both the HIIT and MICE groups (9% and 15%, p < 0.01). HIIT was mainly associated with a greater improvement in overall reaction time in the executive components of the computerized Stroop task (980.43 ± 135.27 ms vs. 860.04 ± 75.63 ms, p < 0.01) and the trail making test (42.35 ± 14.86 s vs. 30.35 ± 4.13 s, p < 0.01). T exercise protocol was clearly an important factor in improving executive functions in young adults.

Children's Perceptions of Economic Groups in a Context of Limited Access to Opportunities
Children (N = 267, ages 8-14 years, M = 11.61 years, middle to upper-middle income) made predictions regarding groups of same-aged peers from high-wealth and low-wealth backgrounds. The context involved granting access to a special opportunity. From middle childhood to early adolescence children increasingly expected both high- and low-wealth groups to want access to opportunities for their own group. However, children viewed high-wealth groups as motivated in part by selfishness and low-wealth groups as concerned in part with broader economic inequality. Finally, the higher children's family income, the more they expected group-serving tendencies. These findings revealed children's perceptions of exclusive preferences between economic groups, negative stereotypes about high-wealth children, and awareness of some of the constraints faced by low-wealth children.

Challenging Gender Stereotypes: Resistance and Exclusion
The likelihood of resisting gender-stereotypic peer group norms, along with expectations about personal resistance, was investigated in 9- to 10-year-olds and 13- to 14-year-olds (N = 292). Participants were told about a stereotype conforming group (boys playing football; girls doing ballet) and a stereotype nonconforming group (boys doing ballet; girls playing football). Contrary to expectations from gender-stereotyping research, participants stated that they would personally resist gender-stereotypic norms, and more so than they would expect their peers to resist. However, expecting peers to resist declined with age. Participants expected that exclusion from the group was a consequence for challenging the peer group, and understood the asymmetrical status of gender stereotypes with an expectation that it would be more difficult for boys to challenge stereotypes than for girls.
