Additive and synergistic relations of early mother–child and caregiver–child interactions and socioeconomic outcomes in adulthood

Prior theoretical and empirical studies have linked the first 3 years of children's life with later life outcomes. One primary explanation is the critical role these experiences play in children's early brain development (including their early language and cognitive abilities) and subsequent schooling achievement. The current study is a registered report with two complementary research objectives: (1) examine to what extent stimulating and responsive interactions with mothers and nonparental caregivers during the first 3 years of life show additive or synergistic associations with key socioeconomic outcomes in adulthood (i.e., educational attainment, salary, and employment status), and (2) examine to what extent academic skills (i.e., mathematics, vocabulary, and literacy) during childhood and adolescence mediate these associations. The sample included 1364 individuals from a birth cohort study who were followed until age 26. Mother–child interactions had positive associations with educational attainment and negative associations with full-time employment, though no synergistic associations were found for the socioeconomic outcomes. In addition, the indirect effects of mother–child interactions on educational attainment through mathematics were strongest for children with less stimulating and responsive caregiver–child interactions. Potential implications of these findings for developmental theory are discussed.

Examining auditory kappa effects through manipulating intensity differences between sequential tones

The auditory kappa effect is a tendency to base the perceived duration of an inter-onset interval (IOI) separating two sequentially presented sounds on the degree of relative pitch distance separating them. Previous research has found that the degree of frequency discrepancy between tones extends the subjective duration of the IOI. In Experiment 1, auditory kappa effects for sound intensity were tested using a three-tone, AXB paradigm (where the intensity of tone X was shifted to be closer to either Tone A or B). Tones closer in intensity level were perceived as occurring closer in time, evidence of an auditory-intensity kappa effect. In Experiments 2 and 3, the auditory motion hypothesis was tested by preceding AXB patterns with null intensity and coherent intensity context sequences, respectively. The auditory motion hypothesis predicts that coherent sequences should enhance the perception of motion and increase the strength of kappa effects. In this study, the presence of context sequences reduced kappa effect strength regardless of the properties of the context tones.     

Interactive Influences of Gender Identity and Gender Typing on Early Adolescents’ Well-Being

We examined whether protective forms of gender identity (typicality, contentedness) ameliorate the negative influences of self-perceived cross gender typing (gender differentiated friendship styles) on early adolescents’ well-being. Early adolescents (N?=?244, 123 girls, M age 12.77 years) in Surrey, England responded to self-reports of friendship styles (preoccupied, avoidant), gender identity (typicality, contentedness), and well-being (self-esteem, depression). Girls reported higher scores than boys on the preoccupied friendship style, and lower scores than boys on the avoidant friendship style. Children who reported a cross gender style (preoccupied for boys and avoidant for girls) also reported poor well-being, indicating that self-perceived cross gender typing is distressing. However, these influences were buffered for youths who reported high levels of gender typicality and gender contentedness. Results suggest that gender identity plays a self-regulatory role in discounting self-perceived gender-atypical attributes that interfere with early adolescents’ sense of well-being.     

Avoidance of overlearning characterises the spacing effect

The spacing of a fixed amount of study time across multiple sessions usually increases subsequent test performance—a finding known as the spacing effect. In the spacing experiment reported here, subjects completed multiple learning trials, and each included a study phase and a test. Once a subject achieved a perfect test, the remaining learning trials within that session comprised what is known as overlearning. The number of these overlearning trials was reduced when learning trials were spaced across multiple sessions rather than massed in a single session. In addition, the degree to which spacing reduced overlearning predicted the size of the spacing effect, which is consistent with the possibility that spacing increases subsequent recall by reducing the occurrence of overlearning. By this account, overlearning is an inefficient use of study time, and the efficacy of spacing depends at least partly on the degree to which it reduces the occurrence of overlearning.     

The Effects of Elevated Arousal and Mood on Maximal Strength Performance in Athletes

Optimal arousal models contend that high arousal contributes to inhibited athletic performance, whereas there is reversal theory research which indicates that high positive arousal may enhance performance. To test these claims, 22 male and 6 female elite athletes were induced into high arousal telic (goal-directed) and high arousal paratelic (non goal-directed, process focussed) motivational states and tested on a standard hand strength task. Personalized guided imagery techniques and paced breathing were used to change psychological and physiological arousal. Significant increases in strength performance occurred when arousal was high and experienced as pleasant excitement in the paratelic condition (i.e., high positive arousal). Heart rate and other indicators of parasympathetic and sympathetic nervous system activity were not found to mediate between psychological arousal and performance. Where athletic performance requires maximal motor strength over a short period, performance benefits of high arousal may be maximized by restructuring motivational state.     

The Role of Resonance in Performance Excellence and Life Engagement

This article presents a concept underlying excellence called resonance , which was developed based on research interviews and consulting practice with high-level performers from all walks of life. Findings suggest that many high-caliber performers follow a typical process as they become experts in their chosen field. They have a dream , which represents how they want to feel in their daily pursuits. They also engage in extensive preparation, which includes activities that enable them to live their dream. All of the participants faced obstacles, but they developed strategies to revisit their dream before they actually engaged in more preparation. This cyclical process that guided their performance and life has been termed resonance , which occurs when there is a seamless fit between their internal self and their external environment. It is captured in the resonance performance model (RPM), a heuristic model devised to guide the practice of consultants. The article also includes a discussion of the RPM in relation to other performance-related concepts such as flow, presents some recent and future research with resonance, and considers practical application for consultants who may be interested in using the RPM.     

Associations amongst disease severity,religious coping and depression in a cohort of Jamaicans with sickle-cell disease

The purpose of this study was to investigate the relationship between disease severity (sickle-cell type and hospital, emergency room and clinic emergency visits (CEU)), religious coping (positive and negative) and depression. This was accomplished through secondary analysis of a data set based on a Comprehensive Sickle Cell Standardized Questionnaire compiled by a multidisciplinary team of professionals from Duke University Medical Centre, and administered to persons with sickle-cell disease being treated at the Sickle Cell Unit on the University of the West Indies Campus between November 2008 and January 2009. Disease severity was not a good predictor of depression within the population. On the other hand, depression was found to correlate with positive and negative religious coping, such that increases in the former were associated with decreases in depression scores; while the reverse was noted for the latter (negative religious coping). The results shed light on issues that could possibly impact the treatment plan for such individuals.
