How to detect which variables are causing differences in component structure among different groups

When comparing the component structures of a multitude of variables across different groups, the conclusion often is that the component structures are very similar in general and differ in a few variables only. Detecting such “outlying variables” is substantively interesting. Conversely, it can help to determine what is common across the groups. This article proposes and evaluates two formal detection heuristics to determine which variables are outlying, in a systematic and objective way. The heuristics are based on clusterwise simultaneous component analysis, which was recently presented as a useful tool for capturing the similarities and differences in component structures across groups. The heuristics are evaluated in a simulation study and illustrated using cross-cultural data on values.     

Peer relationships and adolescents’ academic and non‐academic outcomes: Same‐sex and opposite‐sex peer effects and the mediating role of school engagement

Background. The literature has documented theoretical/conceptual models delineating the facilitating role of peer relationships in academic and non‐academic outcomes. However, the mechanisms through which peer relationships link to those outcomes is an area requiring further research. Aims. The study examined the role of adolescents’ perceptions of their relationships with same‐sex and opposite‐sex peers in predicting their academic performance and general self‐esteem and the potentially mediating role of school engagement in linking these perceived peer relationships with academic and non‐academic outcomes. Sample. The sample comprised 1,436 high‐school students (670 boys, 756 girls; 711 early adolescents, 723 later adolescents). Method. Self‐report measures and objective achievement tests were used. Structural equation modelling (SEM) was performed to test the hypothesized model and its invariance across gender and age groups. Results. Perceived same‐sex peer relationships yielded positive direct and indirect links with academic performance and general self‐esteem. Perceived opposite‐sex peer relationships yielded positive direct and indirect links with general self‐esteem and an indirect positive link with academic performance, but mediation via school engagement was not as strong as that of perceived same‐sex peer relationships. These findings generalized across gender and age groups. Conclusion. Adolescents’ same‐sex and opposite‐sex peer relationships seem to positively impact their academic performance and general self‐esteem in distinct ways. It appears that school engagement plays an important role in mediating these peer relationship effects, particularly those of same‐sex peer relationships, on academic and non‐academic functioning. Implications for psycho‐educational theory, measurement, and practice are discussed.     

EMDR: eye movements superior to beeps in taxing working memory and reducing vividness of recollections

Posttraumatic stress disorder (PTSD) is effectively treated with eye movement desensitization and reprocessing (EMDR) with patients making eye movements during recall of traumatic memories. Many therapists have replaced eye movements with bilateral beeps, but there are no data on the effects of beeps. Experimental studies suggest that eye movements may be beneficial because they tax working memory, especially the central executive component, but the presence/degree of taxation has not been assessed directly. Using discrimination Reaction Time (RT) tasks, we found that eye movements slow down RTs to auditive cues (experiment I), but binaural beeps do not slow down RTs to visual cues (experiment II). In an arguably more sensitive “Random Interval Repetition” task using tactile stimulation, working memory taxation of beeps and eye movements were directly compared. RTs slowed down during beeps, but the effects were much stronger for eye movements (experiment III). The same pattern was observed in a memory experiment with healthy volunteers (experiment IV): vividness of negative memories was reduced after both beeps and eye movements, but effects were larger for eye movements. Findings support a working memory account of EMDR and suggest that effects of beeps on negative memories are inferior to those of eye movements.     

Planning what not to eat: ironic effects of implementation intentions negating unhealthy habits

The present studies tested the effectiveness of implementation intentions with an "if [situation], then not [habitual response]" structure. Based on ironic process theory and the literature on the processing of negations, it was expected that these "negation implementation intentions" would, ironically, strengthen the habit (situation-response association) one aims to break. In line with the hypotheses, forming negation implementation intentions resulted in cognitive ironic rebound effects as well as behavioral ironic rebound effects compared to an intention only condition or a replacement implementation intention. Additionally, it was found that negation implementation intentions are most likely to result in ironic rebound effects when the habit to be negated is strong. Although implementation intentions are generally highly effective in facilitating behavior change even when this involves breaking unwanted habits, the present research suggests that they are ineffective when they have a negating structure.     

Acculturation and emotion among Asian Americans

This study examined the emotion experience of Asian Americans in relation to respondents' orientation to acculturation: Assimilation, Integration, Separation, or Marginalization (J. W. Berry, 1980). Ego- versus other-focused emotion experiences (H. R. Markus & S. Kitayama, 1991) and attention and valence, 2 stages in P. C. Ellsworth's (1994) model of emotion appraisal, were used to investigate the relation between acculturation and affect. Asian Americans most and least assimilated to the dominant Anglo American culture were expected to exhibit emotion responses correspondingly similar to and different from those of Anglo Americans. Those with a bi-cultural or integrationist trajectory should occupy a middle ground in terms of emotional experience. Compared with the appraisal process, ego- versus other-focused emotions, mediated in part by one's self-construal (e.g., independent or interdependent), were more strongly associated with acculturation orientation in the expected directions. The implications of recognizing the influence of acculturation on the emotional meaning of life encounters of newcomers are discussed in light of community psychology and clinical practice.     

Ethnic self-awareness as a function of ethnic group status,group composition,and ethnic identity orientation

This study found that ethnic self-awareness (i.e., the extent to which people are consciously aware of their ethnicity at any given moment) has different meanings for European Americans and Asian Americans and for Asian Americans with different ethnic identity orientations. The authors found main effects of ethnic group status and ethnic composition on ethnic self-awareness when comparing Asian Americans and European Americans. There was also an interaction effect between ethnic composition and ethnic identity orientation for Asian Americans when examining ethnic self-awareness. Findings are discussed in relation to theories that predict salience of ethnicity and to educators and practitioners who deal with ethnic minority group members.

Adolescents' responses to online peer conflict: How self‐evaluation and ethnicity matter

For parents, online platforms where their children interact with others often feel like a “black box” in terms of what exactly is happening. In this study, we developed an ecologically valid online computer game in which a (computer‐generated) peer teammate tried to provoke frustration, in order to examine (a) adolescents' responses and (b) how indices of self‐evaluation (i.e., sense of coherence and self‐esteem) and demographic variables (i.e., gender and ethnicity) matter to these responses. Like gender, being a member of a minority or majority group may influence how provocations by peers are interpreted, influencing how one responds. Fifteen‐year‐old Dutch and Moroccan‐Dutch adolescents (N = 167) completed self‐reports and played the online computer game. The game indeed elicited frustration, with increased self‐reported anger. Moreover, expressions of displeasure were much more common during and after provocation than before provocation. Crucially, perceived self‐evaluation mattered; higher levels of sense of coherence but lower levels of self‐esteem (only in Moroccan‐Dutch group) contributed to fewer expressions of displeasure. Gender did not play a moderating role. Our findings provide initial insights into individual differences in adolescents' responses in an online peer‐conflict situation.

Highlights

• We studied Dutch and Moroccan-Dutch adolescents' responses during online peer provocation and how self-evaluation and demographic variables matter.
• Provocation by the (computer-generated) peer teammate increased expressions of displeasure.
• More sense of coherence but less self-esteem was associated with fewer expressions of displeasure, but ethnicity moderated the effect with self-esteem.
