Exploring the Association Between Peace of Mind and Academic Engagement: Cross-Sectional and Cross-Lagged Panel Studies in the Philippine Context

Peace of mind (PoM) has been associated with positive psychological and well-being outcomes. However, it seems that limited research has been done to assess the role of PoM in the educational setting. The present study addressed this gap through examining the association of PoM with academic engagement via a cross-sectional (Study 1) and a two-wave cross-lagged study (Study 2) in the Philippine setting. Results of hierarchical regression in Study 1 revealed that PoM was positively associated academic engagement even after controlling for relevant demographic variables, positive affect, and life satisfaction. In Study 2, results of the cross-lagged structural equation modeling showed that Time 1 PoM was associated with higher extent of Time 2 academic engagement even after controlling for autoregressor effects, Time 1 positive affect, and Time 1 life satisfaction. Theoretical and practical implications are discussed.     

East–West European Project: Transforming and Shaping Research Through Collaboration

This article tells the story of the journey made by an international research group of social psychologists in their collaborative projects carried out over a number of years after the collapse of communism in Europe in 1989. The article explores some relations between the aims of research conducted during a period of rapid political, social and economic change in Central and Eastern Europe, and the ways these studies were shaped and transformed through collaboration. It shows how the collaboration of researchers in the team affected the development of theoretical concepts and methodological ideas over the years, as well as how the team learned from mistakes. Collaborative efforts cannot be viewed separately from the content of research. Moreover, this international collaborative research has shown that the relationships between institutional and cultural changes cannot be understood by means of comparing phenomena across different countries but by case studies in individual countries.

What skilled typists don’t know about the QWERTY keyboard

We conducted four experiments to investigate skilled typists’ explicit knowledge of the locations of keys on the QWERTY keyboard, with three procedures: free recall (Exp.?1), cued recall (Exp.?2), and recognition (Exp.?3). We found that skilled typists’ explicit knowledge of key locations is incomplete and inaccurate. The findings are consistent with theories of skilled performance and automaticity that associate implicit knowledge with skilled performance and explicit knowledge with novice performance. In Experiment?4, we investigated whether novice typists acquire more complete explicit knowledge of key locations when learning to touch-type. We had skilled QWERTY typists complete a Dvorak touch-typing tutorial. We then tested their explicit knowledge of the Dvorak and QWERTY key locations with the free recall task. We found no difference in explicit knowledge of the two keyboards, suggesting that typists know little about key locations on the keyboard, whether they are exposed to the keyboard for 2 h or 12 years.     

Bicultural identities: The interface of cultural, personality, and socio-cognitive processes

This paper presents recent work examining the meaning and impact of individual variations in the way bicultural individuals organize their two cultural identities, a construct that we call Bicultural Identity Integration (BII). While biculturals high on BII describe their two cultural identities as ‘compatible’ (fluid and complementary), biculturals low on BII experience them as largely ‘oppositional’ (i.e., conflicting and disparate). We first report experimental evidence for how variations in BII moderate biculturals’ socio-cognitive behavior, specifically, the way in which bicultural individuals process cultural knowledge and use it to interpret social behavior. We then report structural equation modeling findings that elucidate some important personality, contextual, and performance predictors of BII. Finally, we conclude with a brief discussion of how the study of bicultural identities provides an ideal ground for the integration of cultural and personality psychology.     

A combined planning and self-efficacy intervention to promote physical activity: a multiple mediation analysis

Many individuals are motivated to improve their physical activity levels, but often fail to act upon their intention. Interventions fostering volitional strategies, such as action planning, coping planning, and self-efficacy beliefs, can help to translate intentions into behavior. This study examines the effectiveness and the mechanisms of a combined planning and self-efficacy intervention to promote physical activity among motivated individuals. Participants (N = 883) were randomly assigned to the intervention or to a waiting-list control condition. Multivariate analysis of variance revealed that the intervention resulted in significantly more physical activity, higher levels of action planning, coping planning, and volitional self-efficacy beliefs (p < 0.01). In addition, multiple mediation analysis showed that action planning, coping planning, and volitional self-efficacy mediate between the intervention and physical activity. The study shows that the intervention successfully fostered physical activity and unfolds the underlying self-regulatory mechanisms of the intervention's effectiveness.     

Understanding the role of uncertainty on learning and retention of predator information

Due to the highly variable nature of predation risk, prey animals need to continuously collect information regarding the risk posed by predators. One question that ensues is how long to use this information for? An adaptive framework of predator-related information use predicted that certainty should influence the duration for which information regarding the threatening nature of a species is used in decision-making. It predicts that uncertainty contributes to the reduction in the duration of information use, due to the cost of displaying antipredator behaviours towards non-threatening species. Here, we test this prediction using repetition of conditioning events as a way to increase the certainty associated with the predatory nature of a novel salamander for woodfrog tadpoles. Tadpoles were conditioned 1, 2 or 4 times to recognize a novel salamander as a predator and subsequently tested for their response to the salamander 1?day or 11?days post-conditioning. We found that conditioning repetition did not affect the intensity with which tadpoles learned to respond to the salamander after 1?day. However, after 11?days, tadpoles with fewer conditionings responded to the salamander with a weaker intensity than those that received more conditionings. Our results provide support for the model prediction that an increase in the certainty associated with correctly identifying a predator leads to longer retention of the threat.     

Oxidative stress in university students during examinations

Mental stress in psychiatric disease and in daily life contributes to oxidative stress in the body. In this study we investigated a connection between possible psychological stress caused by university undergraduate examinations and oxidative stress experienced by our test subjects. Some parameters of oxidative stress (single strand breaks of DNA in lymphocytes, sensitivity to lipid oxidation and antioxidant status) were studied in medical students on the day of the examination (stress condition) and compared with the same parameters obtained from the same students during the term between two examination periods (non-stress condition). The results show that in the stress condition oxidative damage to DNA and sensitivity to lipid oxidation were significantly increased (p<0.05) when compared with the same parameters in "non-stress" conditions. A significant decrease in plasma antioxidant activity (p<0.05) in students that were under stress was observed. These results suggest that during university examinations students are under increased oxidative stress.     

Serotonergic dysfunction: Brain imaging and behavioral correlates

Identification of gene-environment and gene-gene interactions has become increasingly important in understanding psychiatric disorders. Dysfunction of central serotonergic neurotransmission has been implicated in alcoholism, depression, and anxiety. We review the literature on nonhuman primates that assesses the interaction between the genetic constitution of the regulatory region of the serotonin transporter (5-HTT) and environmental factors. Prospective studies in nonhuman primates that underwent social stress found a reduction of the serotonin turnover rate among carriers of one or two short alleles in a functional polymorphism of the 5-HTT promoter. In these primates, brain imaging studies showed a relative increase in the availability of raphe serotonin transporters. A low serotonin turnover rate and a high availability of serotonin transporters were associated with reduced response to excessive alcohol intake, anxiety, and impulsive aggression. Animal experiments point to a relationship between serotonergic dysfunction, negative mood states, and excessive alcohol intake, which may in part be mediated by reduced alcohol-induced sedation.     

Culture and egocentric perceptions of fairness in conflict and negotiation

In this article, the authors advanced a cultural view of judgment biases in conflict and negotiation. The authors predicted that disputants' self-serving biases of fairness would be more prevalent in individualistic cultures, such as the United States, in which the self is served by focusing on one's positive attributes to "stand out" and be better than others, yet would be attenuated in collectivistic cultures, such as Japan, where the self is served by focusing on one's negative characteristics to "blend in" (S. J. Heine, D. R. Lehman, H. R. Markus, & S. Kitayama, 1999). Four studies that used different methodologies (free recall, scenarios, and a laboratory experiment) supported this notion. Implications for the science and practice of negotiation are discussed.     

Can Inattention/Overactivity Be an Institutional Deprivation Syndrome?

Elevated rates of attention deficit and overactivity have been noted previously in samples of institution-reared children. This study examined the hypothesis that inattention/overactivity(I/O) might constitute a specific deprivation syndrome. One hundred and sixty five children adopted at varying ages (e.g., 0–42 months of age) into the UK following severe early deprivation were compared with 52 within-UK adoptees who did not suffer deprivation. The children were rated by teachers and parents on levels of I/O, conduct difficulties, and emotional difficulties using the Revised Rutter Scales. Data were collected at age 6 for the entire sample and at age 4 for the UK adoptees and for the subsample of Romanian children who entered the UK before the age of 2 years. Mean level analyses suggested a significant effect of duration of deprivation on I/O, but not on conduct or emotional difficulties. The effects of duration of deprivation were specific to I/O and were not accounted for by low birth weight, malnutrition, or cognitive impairment. Levels of I/O correlated with attachment disturbances. Furthermore, the effects of duration of deprivation on I/O did not attenuate over time. We conclude that I/O may well constitute an institutional deprivation syndrome, but that the type of attention deficit and overactivity exhibited by these children may present a different clinical picture from that of ordinary varieties of attention deficit disorder or hyperkinetic syndrome.
