In- and out-of-school peer groups of immigrant youths

Multiethnic societies typically aim to have immigrant and native youths mix and be friends, preferably in all contexts in which they spend time. Schools and neighbourhoods are the two settings where youths spend the most time with peers during adolescence. The present study explored the in- and out-of-school peer groups of 174 immigrant junior high school pupils (Mean age = 14.39) who attended an integrated school but lived in a segregated neighbourhood. A person-oriented approach was used and cluster analyses were conducted both within and across the two settings. The results show that youths mostly have the same kind of friendship formations in both settings, regardless of the ethnic composition of each setting. In terms of adaptation, the results consistently show that for boys, having only immigrant friends is related to problematic adaptation in both settings. No relationship between peer formations and adaptation was found for girls. The study highlights the importance of considering gender and viewing youths as embedded in systems of multiple settings, in order to achieve true integration.     

The benefits of self-compassion and optimism exercises for individuals vulnerable to depression

The effectiveness of two online exercises intended to help individuals experience (1) self-compassion (n?=?63) and (2) optimism (n?=?55) were compared to a control intervention where participants wrote about an early memory (n?=?70). A battery of tests was completed at 1 week following the exercise period, and at 1-, 3-, and 6-month follow-ups. Both active interventions resulted in significant increases in happiness observable at 6 months and significant decreases in depression sustained up to 3 months. The interventions were examined in relationship to dependency and self-criticism, both related to vulnerability to depression. Individuals high in self-criticism became happier at 1 week and at 1 month in the optimism condition in the repeated measures analysis. A sensitivity test using multi-level modeling failed to replicate this effect. More mature levels of dependence (connectedness) were related to improvements in mood up to 6 months in the self-compassion condition. This study suggests that different personality orientations may show greater gains from particular types of positive psychology interventions.     

Influencing value priorities and increasing well-being: The effects of reflecting on intrinsic values

A four-week experimental study (N?=?113) examined the effects of reflecting on intrinsic values. In the experimental group, participants learned about the distinction between intrinsic (e.g. having close relationships) and extrinsic (e.g. being popular) values, wrote about two personal intrinsic values, and then reflected on these values weekly for four weeks. In the control group, participants completed parallel exercises related to the daily details of their lives. Results revealed that participants in the intrinsic values group experienced greater well-being immediately following the written reflection than participants in the control group. Four weeks later, the more engaged participants felt in the reflection exercises, the more they prioritized intrinsic over extrinsic values and the greater their well-being. These effects occurred only for participants in the intrinsic values condition. The implications for changing value priorities and improving well-being are discussed.     

Happy-productive groups: How positive affect links to performance through social resources

Abstract

The current study extends the Broaden & Build theory to the collective (i.e. groups) level of analysis, focusing on the mediating role of group social resources (i.e. cohesion, coordination, teamwork, supportive team climate) between group positive affect (i.e. enthusiasm, optimism, satisfaction, comfort) and group performance (i.e. in-and extra-role performance, creative performance). To test our hypotheses, we conducted two studies using independent samples. Study 1 is a laboratory study with 449 participants nested in 112 small groups who performed an organizational simulation creative task. Study 2 is a field study that aggregated scores of 2159 employees nested in 417 groups. In both the lab and field studies, structural equation modeling results revealed that group social resources fully mediate the relationship between group positive emotions and performance.     

Positive emotions,hope, and life satisfaction in Chinese adults: a test of the broaden-and-build model in accounting for subjective well-being in Chinese college students

ABSTRACT

The present study sought to determine if the positive association between positive emotions and life satisfaction can be understood as a function of hope in Chinese. Consistent with the broaden-and-build model of positive emotions, we tested the hypothesis that positive affectivity, the disposition to experience positive emotions, would be associated with broadening hope agency, building hope pathways, or both, in a sample of 212 Chinese college students. Results examining for bootstrapped mediation testing with multiple mediators indicated that positive affectivity was indirectly associated with life satisfaction through hope agency, but not through hope pathways. In support for partial mediation, however, the association between positive affectivity and life satisfaction remained significant even after including hope components in the model. Some implications of the present findings are discussed.     

Ecological issues of justice

In the first part of this article the author explores the implications for justice of the wider range of parties holding moral standing that environmental ethics has recently disclosed. These implications concern the equitable treatment of future generations and nonhuman creatures, and are relevant both to policies, such as approaches to global warming, and procedures, which may need to be revised to give an equitable voice to unrepresented interests. Later the author considers some radical implications of regarding humanity as stewards of the planetary environment, a view defended in his recent book Creation, Evolution and Meaning. If all adult humans have this role, but many are prevented from discharging it by poverty and related constraints, then those who are thus disempowered need to be empowered to exercise this role. This requirement of equity would arise not from their moral patienthood but from what is involved in respecting them as moral agents. Some approaches to tackling global warming are considered in this connection.     

Is advance reconfiguration in voluntary task switching affected by the design employed?

In task switching, when the amount of preparation time is increased, a reduction in switch cost or RISC effect is observed. This RISC effect is frequently attributed to advance reconfiguration processes. In the explicit task-cueing procedure, RISC effects are observed when varying the preparation time within participants but not when varying the preparation time across participants—a finding suggesting that RISC effects in the explicit task-cueing procedure are restricted to specific designs. The present study investigated RISC effects in voluntary task switching and compared RISC effects in a within-subjects design with RISC effects in a between-subjects design. Our results indicate that RISC effects are present in both designs. We conclude that advance reconfiguration in voluntary task switching is robust.     

Coding categorical and coordinate spatial relations in visual–spatial short-term memory

Four experiments explored the coding of categorical and coordinate spatial relations in visual–spatial short-term memory (VSSTM). Participants judged whether two stimuli presented successively on a computer screen were the same or different. On positional change trials the two stimuli differed in the position of one element. Positional changes were of two types, coordinate and categorical. On coordinate trials the position of one element changed by a small amount, but retained the categorical relationships (above, below, left of, right of) to all other elements. On categorical trials one element moved by the same amount but additionally changed its categorical relationship to one of the other elements (e.g., changed from below to above). Participants detected categorical changes more accurately than coordinate changes when the elements were independent locations marked by squares, indicating that the categorical relationships amongst the squares were encoded in memory. Furthermore, this categorical advantage was unmodulated by either the suppression of articulation (Experiment 2) or by the requirement to retain either colour–position associations or positions only (Experiment 3). When the elements to be remembered were the vertices of simple outline polygons (Experiment 4) there was no categorical advantage, establishing the effect as spatial in nature. Contrary to predictions derived from Postma and De Haan (1996) Postma, A. and De Haan, E. H. 1996. What was where? Memory for object locations. Quarterly Journal of Experimental Psychology, 49A: 178–199. [Crossref], [Web of Science ®] , [Google Scholar], the employment of categorical relations appears not to be specifically linked to either verbal coding or to the requirement to associate objects with positions. The results suggest that the categorical relations are an intrinsic property of the representation of spatial configurations.     

Sentence comprehension affects the dynamics of bimanual coordination: Implications for embodied cognition

Recent work in embodied cognition has demonstrated that language comprehension involves the motor system (e.g., Glenberg & Kaschak, 2002). Such findings are often attributed to mechanisms involving simulations of linguistically described events (Barsalou, 1999; Fischer & Zwaan, 2008). We propose that research paradigms in which simulation is the central focus need to be augmented with paradigms that probe the organization of the motor system during language comprehension. The use of well-studied motor tasks may be appropriate to this endeavour. To this end, we present a study in which participants perform a bimanual rhythmic task (Kugler & Turvey, 1987) while judging the plausibility of sentences. We show that the dynamics of the bimanual task differ when participants judge sentences describing performable actions as opposed to sentences describing events that are not performable. We discuss the general implications of our results for accounts of embodied cognition.     

Estimating the effect of word predictability on eye movements in Chinese reading using latent semantic analysis and transitional probability

Latent semantic analysis (LSA) and transitional probability (TP), two computational methods used to reflect lexical semantic representation from large text corpora, were employed to examine the effects of word predictability on Chinese reading. Participants' eye movements were monitored, and the influence of word complexity (number of strokes), word frequency, and word predictability on different eye movement measures (first-fixation duration, gaze duration, and total time) were examined. We found influences of TP on first-fixation duration and gaze duration and of LSA on total time. The results suggest that TP reflects an early stage of lexical processing while LSA reflects a later stage.
