A Brain-Based Account of the Development of Rule Use in Childhood

ABSTRACT— The ability to follow explicit rules improves dramatically during the course of childhood, but relatively little is known about the changes in brain structure and function that underlie this behavioral improvement. Drawing from neuroscientific studies in human adults and other animals, as well as from an emerging literature in developmental cognitive neuroscience, we propose a brain-based account of the development of rule use in childhood. This account focuses on four types of rules represented in different parts of the prefrontal cortex: simple rules for reversing stimulus–reward associations, pairs of conditional stimulus–response rules (both univalent and bivalent), and higher-order stimulus–response rules for selecting among task sets. It is hypothesized that the pattern of developmental changes in rule use reflects the different rates of development of specific regions within the prefrontal cortex.     

A Social-Neuroscience Perspective on Empathy

ABSTRACT— In recent years, abundant evidence from behavioral and cognitive studies and functional-imaging experiments has indicated that individuals come to understand the emotional and affective states expressed by others with the help of the neural architecture that produces such states in themselves. Such a mechanism gives rise to shared representations, which constitutes one important aspect of empathy, although not the sole one. We suggest that other components, including people's ability to monitor and regulate cognitive and emotional processes to prevent confusion between self and other, are equally necessary parts of a functional model of empathy. We discuss data from recent functional-imaging studies in support of such a model and highlight the role of specific brain regions, notably the insula, the anterior cingulate cortex, and the right temporo-parietal region. Because this model assumes that empathy relies on dissociable information-processing mechanisms, it predicts a variety of structural or functional dysfunctions, depending on which mechanism is disrupted.     

Age and burnout syndrome in nursing professionals: moderating role of emotion-focused coping

This study examined whether the association between age and the three burnout dimensions (emotional exhaustion, depersonalisation and reduced personal accomplishment) depend on the extent of nursing professionals’ use of emotion-focused coping strategy. Participants were 283 nurses (Mage = 35 years, SD = 8.17, Range = 23–66 years) from a tertiary healthcare institution in south-eastern Nigeria. They completed self-report measures of relevant variables in paper and pencil form. Increased age was associated with reduced personal accomplishment for nurses with high emotion-focused coping, but not for those who were low or moderate in use of emotion-focused coping. Such moderation effects were not found for emotional exhaustion and depersonalisation. Findings clarify the conditions under which age may be associated with reduced sense of achievement at work among nursing professionals. The study adds to knowledge in combating burnout in nursing and could guide health managers in developing strategies that might prevent or ameliorate nurses’ burnout.     

Rational beliefs,happiness and optimism: An empirical assessment of REBT's model of psychological health

This study sought to test the validity of the psychological health model of Rational Emotive Behaviour Therapy (REBT). Specifically, this study sought to investigate if rational beliefs were associated with happiness and optimism. A multinational sample of 397 university students completed self‐report measures of rational beliefs, happiness and optimism. Structural equation modelling (SEM) was used in order to test the validity of the REBT model of psychological health. The result of the SEM analysis provided empirical support for REBT's psychological health model of happiness and optimism. The model as a whole explained 33% of variance in levels of happiness and 40% of variance in levels of optimism. Self‐acceptance beliefs were positively and directly associated with happiness and optimism. Preference beliefs were positively and indirectly associated with happiness and optimism via self‐acceptance beliefs. REBT may offer a viable psychotherapeutic method to not only alleviate psychological distress, but also build positive emotion. Current findings may help to bridge the divide between the fields of positive psychology and clinical psychology.

The Effect of Paired Muscle Stimulation on Preparation for Movement

Paired muscle stimulation is used clinically to facilitate the performance of motor tasks for individuals with motor dysfunction. However, the optimal temporal relationship between stimuli for enhancing movement remains unknown. We hypothesized that synchronous, muscle stimulation would increase the extent to which stimulated muscles are concurrently prepared for movement. We validated a measure of muscle-specific changes in corticomotor excitability prior to movement. We used this measure to examine the preparation of the first dorsal interosseous (FDI), abductor digiti minimi (ADM), abductor pollicis brevis (APB) muscles prior to voluntary muscle contractions before and after paired muscle stimulation at four interstimulus intervals (0, 5, 10, and 75 ms). Paired muscle stimulation increased premovement excitability in the stimulated FDI, but not in the ADM muscle. Interstimulus interval was not a significant factor in determining efficacy of the protocol. Paired stimulation, therefore, did not result in a functional association being formed between the stimulated muscles. Somatosensory potentials evoked by the muscle stimuli were small compared to those commonly elicited by stimulation of peripheral nerves, suggesting that the lack of functional association formation between muscles may be due to the small magnitude of afferent volleys from the stimulated muscles, particularly the ADM, reaching the cortex.     

Relational Spirituality,Mature Alterity,and Spiritual Service among Ministry Leaders: An Empirical Study

Christian communities in the United States increasingly are debating sociopolitical issues and the relevance of social justice and cultural diversity to Christian spirituality. The present study investigated connections between spiritual maturity, mature alterity, spiritual service, and spiritual leadership in a predominantly female and ethnically diverse sample of Christian ministry leaders (N = 115) in the United States. Spiritual maturity was operationalized based on a relational spirituality model using measures representing dwelling- and seeking-oriented dimensions. Spiritual service was assessed through (a) sanctification of service and (b) a differentiated posture of listening to the struggles of others. Results showed both measures of spiritual maturity were significantly and positively related to social justice commitment, differentiated listing, and intercultural competence (the latter among female but not male ministry leaders) over and above effects for age and spiritual impression management. A dwelling-oriented measure of spiritual maturity was positively associated with the sanctification of leadership service, whereas a seeking-oriented measure of spiritual maturity showed a modest positive association with spiritual leadership. Spiritual leadership was unrelated to measures of mature alterity. Findings are discussed with respect to limitations, future psychological research, and theological implications for postcolonial pastoral leadership and spirituality.

     

Parental illness intrusiveness and youth glycaemic control in type 1 diabetes: intergenerational associations and processes

Objective: This study examined associations between the functioning of youth with type 1 diabetes and their parents, including parenting dimensions as intervening mechanisms. The study adds to the existing literature by focusing on (1) the concept of parental illness intrusiveness; (2) the (understudied) periods of adolescence and emerging adulthood; and (3) maternal and paternal functioning. Design: Questionnaires were completed by 317 patient-mother dyads and 277 patient-father dyads. All patients (aged 14–25) had type 1 diabetes. The hypothesised model was compared to an alternative model using structural equation modelling. Main Outcome Measures: Youth reported on depressive symptoms and treatment adherence; Physicians provided HbA_1c-values. Parents reported on illness intrusiveness, depressive symptoms, and their child’s treatment adherence. Patients and parents reported on psychological control and overprotection. Results: The hypothesised path model had a good fit to the data. Parental illness intrusiveness was positively associated with depressive symptoms and both were positively related to overprotection and psychological control. Psychological control was positively related to patients’ depressive symptoms and negatively to treatment adherence. Poorer treatment adherence was associated with worse HbA_1c-values. Conclusion: These findings underscore the relevance of parental illness intrusiveness and emphasise the importance of mothers’ and fathers’ roles throughout adolescence and emerging adulthood.     

Approach-motivated positive affect reduces breadth of attention

Research has found that positive affect broadens attention. However, these studies have manipulated positive affect that is low in approach motivation. Positive affect that is high in approach motivation should reduce the breadth of attention, as organisms shut out irrelevant stimuli as they approach desired objects. Four studies examined the attentional consequences of approach-motivated positive-affect states. Results were consistent with predictions. Participants showed less global attentional focus after viewing high-approach-motivating positive stimuli than after viewing low-approach-motivating positive stimuli (Study 1) or neutral stimuli (Study 2). Study 3 found that greater trait approach motivation resulted in less global attentional focus after participants viewed approach-motivating positive stimuli. Study 4 manipulated affect and approach motivation independently. Greater approach-motivated positive affect caused lower global focus. High-approach-motivated positive affect reduces global attentional focus, whereas low-approach-motivated positive affect increases global attentional focus. Incorporating the intensity of approach motivation into models of positive affect broadens understanding of the consequences of positive affect.
