Color categories and color appearance

We examined categorical effects in color appearance in two tasks, which in part differed in the extent to which color naming was explicitly required for the response. In one, we measured the effects of color differences on perceptual grouping for hues that spanned the blue-green boundary, to test whether chromatic differences across the boundary were perceptually exaggerated. This task did not require overt judgments of the perceived colors, and the tendency to group showed only a weak and inconsistent categorical bias. In a second case, we analyzed results from two prior studies of hue scaling of chromatic stimuli (De Valois, De Valois, Switkes, & Mahon, 1997; Malkoc, Kay, & Webster, 2005), to test whether color appearance changed more rapidly around the blue-green boundary. In this task observers directly judge the perceived color of the stimuli and these judgments tended to show much stronger categorical effects. The differences between these tasks could arise either because different signals mediate color grouping and color appearance, or because linguistic categories might differentially intrude on the response to color and/or on the perception of color. Our results suggest that the interaction between language and color processing may be highly dependent on the specific task and cognitive demands and strategies of the observer, and also highlight pronounced individual differences in the tendency to exhibit categorical responses.     

System justification and the defense of committed relationship ideology

A consequential ideology in Western society is the uncontested belief that a committed relationship is the most important adult relationship and that almost all people want to marry or seriously couple (DePaulo & Morris, 2005). In the present article, we investigated the extent to which the system justification motive may contribute to the adoption of this ideology. In Studies 1 and 2, we examined whether a heightened motive to maintain the status quo would increase defense of committed relationship values. In Study 3, we examined the reverse association, that is, whether a threat to committed relationship ideology would also affect sociopolitical system endorsement. As past research has found that the justification of political systems depends upon how much these systems are perceived as controlling, in Study 4 we tested whether the defense of the system of committed relationships would also increase when framed as controlling. Results from Studies 1-4 were consistent with our hypotheses, but only for men. In Study 5, using cross-cultural data, we sought to replicate these findings correlationally and probe for a cause of the gender effect. Results from more than 33,000 respondents indicated a relationship (for men) between defense of the sociopolitical system and defense of marriage in countries where the traditional advantages of men over women were most threatened. In Studies 6 and 7, we investigated when this gender difference disappears. Results revealed that when we measured (Study 6) or manipulated (Study 7) personal relationship identity rather than relationship ideology, effects also emerge for women.     

The development of the Social Bullying Involvement Scales

This study reports findings of a newly developed measure of social bullying based on Underwood's [2003] framework of social aggression. The Social Bullying Involvement Scales (SBIS) consist of four scales measuring the extent to which children experience social victimization, engage in social bullying, witness social bullying, and intervene in social bullying. The sample consisted of 636 participants (311 females and 325 males, age range 11-16 years; 71% White). Confirmatory factor analysis supported a revised version of Underwood's framework for each of the four participant role scales. Internal consistencies for each scale ranged from .93 to .97. Results revealed that social victimization was related to an increase in anxiety, depressive, and externalizing behaviors. Social bullying was associated with an increase in general externalizing behaviors only. Social witnessing was moderately correlated with depression scores. Intervening in social bullying was not linked with psychological maladjustment or externalizing behaviors. The SBIS provides a comprehensive measure of social victimization, social bullying, social witnessing, and social intervening.

The impact of pressured information management on boys' and girls' psychological functioning

This study involving 463 adolescents examined the impact of pressured information management with mothers on boys' and girls' subsequent psychological functioning. This novel concept of pressured information management involved both pressured secrecy and disclosure and was defined as the degree to which adolescents feel they have no choice but to engage in these strategies. While pressured secrecy was especially aversive for girls, yielding associations with both depression and anxiety, it was related to stress only in boys. Pressured disclosure was less detrimental, and in fact, had a positive influence on girls' anxiety over time. Alternate models for these effects were considered but not supported by the data. Together, these findings highlight the importance of considering teens' reasons for engaging in different information management strategies and suggest adolescents who feel they have no choice but to keep secrets or disclose information to mothers may experience psychological consequences that are gender-specific.

Perception of Candomble Practitioners About Herbal Medicine and Health Promotion in Ceará, Brazil

Candomble, a Brazilian religion of African origin that worships Orishas, promotes “healing” assistance during its worship rituals using therapy with plants and beliefs. From its ancestry tradition, the respect and beware with nature are expressed. Therefore, the aim of this study is to investigate the perception of ethnoecology and health promotion among Candomble practitioners from a Candomble temple in the state of Ceará, Brazil. The ethnography was designed to allow greater immersion into the current mystique. This immersion results in the breaking of existing prejudices and admiration for their worldview. Thus, it can be observed that people seek Candomble to get rid of “bad” health difficulties, such as insomnia, depression, eyesight problems among others, which are commonly treated with herbal preparations, baths, and teas, using plants native to the region; however, their indications are not always in accordance with scientific evidence. In parallel with biomedicine, their hospitable and healthcare practices are considered by most as the equivalent to traditional healthcare actions, but greater recognition of biomedicine is necessary. Based on this perspective, the use of native plants in Candomble is examples of memory, hospitality, and humanization for the community wellness.     

Cyber Victimization and Internalizing Difficulties: The Mediating Roles of Coping Self-Efficacy and Emotion Dysregulation

Cyber victimization has consistently been associated with internalizing difficulties in adolescents. However, the underlying psychological mechanisms linking this relationship have not been adequately examined. The present study aimed to investigate the mediational roles of coping self-efficacy and emotion dysregulation in the relationships between cyber victimization with depression and social anxiety. Participants were 459 students (199 girls) from independent middle-class schools in grades 8 (M _age ?=?13 years 9 months) and 10 (M _age ?=?15 years 7 months). They completed a self-report questionnaire about cyberbullying participation, internalizing symptoms, coping self-efficacy, and emotion dysregulation. Structural equation modeling revealed that most domains of coping self-efficacy and emotion dysregulation partially mediated the relationship between cyber victimization and depression, and fully mediated the relationship between cyber victimization and social anxiety. The results highlight the importance of targeting these mediating factors in intervention programs to reduce the negative impact of cyber victimization on adolescents.
