Emotion-modulated performance and activity in left dorsolateral prefrontal cortex

Functional MRI (fMRI) was used to examine the relationship between processing of pleasant and unpleasant stimuli and activity in prefrontal cortex. Twenty volunteers identified the colors in which pleasant, neutral, and unpleasant words were printed. Pleasant words prompted more activity bilaterally in dorsolateral prefrontal cortex (DLPFC) than did unpleasant words. In addition, pleasant words prompted more activity in left than in right DLPFC. Response speed to pleasant words was correlated with DLPFC activity. These data directly link positive affect, enhanced performance, and prefrontal activity, providing some of the first fMRI evidence supporting models of emotional valence and frontal brain asymmetry based on electroencephalography (EEG).     

Comparing Levels of Spiritual Well-being in State,Catholic and Independent Schools in Victoria,Australia

This article reports on a survey completed by Chaplains, Religious Education and Student Welfare Coordinators in State, Catholic and Independent schools in Victoria. Results from this survey support the model of spiritual well-being, which was seen to be reflected in the quality of relationships that people develop with themselves, others, the environment, and with a Transcendent Other. The staff surveyed generally reported positively on current practice and expressed high priorities for action in nurturing their students' spiritual well-being. School type contributed to significant differences in each of these four sets of relationships.     

EFFECTS OF A FIXED‐TIME SCHEDULE ON ABERRANT AND ADAPTIVE BEHAVIOR

Fixed‐time (FT) schedules of reinforcement have been used to decrease destructive behavior. However, the effects of FT schedules on acquisition and maintenance of appropriate behavior remain unclear. In this study, we present a case in which an FT schedule produced an increase in adaptive behavior and resulted in a significant decrease in destructive behavior.     

Latent variable analyses of age trends of cognition in the Health and Retirement Study, 1992-2004

The present study was conducted to better describe age trends in cognition among older adults in the longitudinal Health and Retirement Study (HRS) from 1992 to 2004 (N = 17,000). The authors used contemporary latent variable models to organize this information in terms of both cross-sectional and longitudinal inferences about age and cognition. Common factor analysis results yielded evidence for at least 2 common factors, labeled Episodic Memory and Mental Status, largely separable from vocabulary. Latent path models with these common factors were based on demographic characteristics. Multilevel models of factorial invariance over age indicated that at least 2 common factors were needed. Latent curve models of episodic memory were based on age at testing and showed substantial age differences and age changes, including impacts due to retesting as well as several time-invariant and time-varying predictors.     

When looks are everything: appearance similarity versus kind information in early induction

The goal of this research was to examine mechanisms underlying early induction--specifically, the relation between induction and categorization. Some researchers argue that even early in development, induction is based on category-membership information, whereas others argue that early induction is based primarily on similarity. Children 4 and 5 years of age participated in two types of tasks: categorization and induction. Both tasks were performed with artificial animal-like categories in which appearance was pitted against category membership. Although the children readily acquired category-membership information and subsequently used this information in categorization tasks, they ignored category membership during the induction task, relying instead on the appearance of items. These results support the idea that early in development, induction is similarity based.     

Treating food selectivity as resistance to change in children with autism spectrum disorder

Change-resistant behavior, such as rigid and selective food consumption, is a core symptom of autism that can have significant negative consequences for the child (Flygare Wallén et al., 2018; Levy et al., 2019). In the current study, we used a matching-law-based intervention (Fisher et al., 2019) to treat the change-resistant feeding behavior of 7 young children with autism. The feeder gave the participant a choice between a change-resistant and an alternative food during free- and asymmetrical-choice conditions. Alternative-food consumption increased for 2 participants during asymmetrical choice when the feeder provided a preferred item for consuming the alternative food and no programmed consequence for consuming the change-resistant food. Alternative-food consumption increased for the other 5 participants after the feeder exposed at least 1 food to single choice in which the feeder guided the participant to put the bite of alternative food in his or her mouth if he or she did not do so within 8 s of presentation. Effects of the single-choice contingencies maintained during reversals and generalized to other alternative foods the feeder did not expose to single choice. These results are important because participants consumed alternative foods even when their change-resistant foods were present, which is similar to typical mealtime contexts in which children have choices among foods.     

Object relations and real life relationships: A cross method assessment

This study examines the relationship between the psychoanalytic concept of object relations and real life behavior of being in an intimate relationship among heterosexual women. In a multi‐method approach we used two different measures; the self‐report Bell Object Relations and Reality Testing Inventory (BORRTI; Bell, Billington & Becker, 1986 ) and the performance based Thematic Apperception Test (TAT) Social Cognition & Object Relations Scale‐ Global Rating Method SCORS‐G (Westen, 1995 ) to measure the object relations of 60 women. The Alienation subscale of the BORRTI and understanding of social causality subscale of the SCORS‐G explained 34.8% of variance of the intimate relationship variable. Thus, women involved in a romantic relationship reported lower rates of alienation on the BORRTI and produced TAT narratives that were more adaptive with regard to understanding of social causality as measured by the SCORS‐G than those not currently in a relationship. Results are discussed with reference to the relationship between object relations and real life measures of healthy individuals and in light of the need for a multi‐method approach of assessment.
