The Role of Life Satisfaction in Predicting Student Engagement and Achievement

Much research has investigated how individual components of subjective well-being (e.g., life satisfaction, positive affect, negative affect) influence adolescent functioning. Little is known, however, about how the third component of subjective well-being (SWB), life satisfaction, contributes to positive adolescent outcomes when investigated simultaneously with positive and negative emotions. The current study extends Lewis et al.’s (J Psychoeduc Assess 27:397–408, 2009. doi:10.1177/0734282908330571) work by considering the incremental validity of life satisfaction (LS) relative to negative affect (NA) and positive affect (PA) as predictors of student engagement and achievement in a sample of middle school students. Results indicated LS provided incremental validity over affective states in predicting student engagement and some aspects of academic achievement. Gender also moderated these relationships. Practitioners are encouraged to include all components of SWB in assessments, especially when trying to understand students’ school functioning.     

Life Satisfaction and Coping in Hindu Adolescents in India

This exploratory study examined the relations between approach and avoidance coping behaviors and general life satisfaction in a sample of 248 Hindu adolescents from an urban area in India. The major findings were threefold. First, gender differences were observed, with females reporting more frequent use of the strategies of seeking social support, direct problem solving, and internalizing behaviors. Second, using multiple regression analyses, the coping behaviors of problem solving and externalizing behaviors accounted for significant, unique variance in life satisfaction scores. Third, gender did not moderate the relations between any of the coping behaviors and life satisfaction. Possible implications for health promotion are discussed.     

Enhanced inhibitory avoidance learning prevents the long-term memory-impairing effects of cycloheximide,a protein synthesis inhibitor

Interference with activity of numerous cerebral structures produces memory deficiencies; in many instances, however, when animals are over-trained such interference becomes innocuous. Systemic administration of protein synthesis inhibitors impairs long-term retention; this effect has been interpreted to mean that protein synthesis is required for memory consolidation, though little is known about the effect of protein synthesis inhibitors on memory of enhanced learning in the rat. To further analyze the protective effect of enhanced learning against amnesic treatments, groups of Wistar rats were trained in a one-trial step-through inhibitory avoidance task, using different intensities of foot-shock during training. Cycloheximide (CXM; 2.8 mg/kg), an inhibitor of protein synthesis, was injected either 30 min before training or immediately after training. Twenty-four hours after training retention latencies were recorded. Our data showed that both pre- and post-training administration of CXM produced amnesia in those groups that had been trained with relatively low foot-shock intensities, but no impairment in retention was observed when relatively high intensities of foot-shock were administered. These and similar results lead us to conclude that protein synthesis inhibitors may interfere with memory consolidation, but their effect disappears when animals are submitted to an enhanced learning experience, calling into question the idea that protein synthesis is required for memory consolidation.
