Effects of induced emotional state on lexical processing in younger and older adults

The authors investigated the effects of an induced emotional mood state on lexical decision task (LDT) performance in 50 young adults and 25 older adults. Participants were randomly assigned to either happy or sad mood induction conditions. An emotional mood state was induced by having the participants listen to 8 min of classical music previously rated to induce happy or sad moods. Results replicated previous studies with young adults (i.e., sad-induced individuals responded faster to sad words and happy-induced individuals responded faster to happy words) and extended this pattern to older adults. Results are discussed with regard to information processing, aging, and emotion.     

The relationship between executive function and verbal memory in Parkinson's disease

A growing body of evidence suggests that the various cognitive symptoms found in Parkinson's disease (PD) are secondary to executive dysfunction. Studies addressing this possibility for memory impairment specifically have not included measures of working memory nor have they ruled-out potential mediating variables such as overall level of cognitive impairment or depression. The purpose of this study was to include measures of these variables in determining the relationship between multiple aspects of executive function and delayed verbal recall in 32 idiopathic PD patients. Results were consistent with the original hypothesis and further suggest that working memory is a key factor in recall memory and may mediate the relationship between other executive measures and recall in PD.     

Personality is associated with perceived health and functional status in older primary care patients

Using data collected on 265 primary care medical patients 60 years of age and older, the authors examined the personality bases of subjective health (perceived health, functional status) after controlling for observer-rated depression and medical burden. Four hypotheses were tested: High Neuroticism is associated with poorer perceived health, low Extraversion is associated with poorer perceived health, low Openness to Experience is associated with worse functional status, and age moderates the relationships between personality and subjective health. Findings supported the notion that personality is associated with subjective health; moreover, this effect appeared to grow more pronounced with increasing age. This study underscores the conceptual and heuristic value of examining moderators of the links between personality variables and health.     

Developmental origins of sociality in brown-headed cowbirds (Molothrus ater)

Five variables were studied relating to the emergence of sociality in hand-reared cowbirds (Molothrus ater): proximity, sex assortment, reactions to adults, head-down displays, and vocalizations. The authors were especially interested in female sociality because adult female birds influence male courtship, song content, and use through proximity, attention, and displays. The authors found that young female birds failed to show same-sex affiliation typical of the species at any point in the study. Brief introduction of adults did not affect social patterns. Adults used more head-down displays than juveniles, who used more displays with familiar peers. Directed and undirected singing emerged concurrently; directed singing was positively correlated with earlier hatching. This is the first demonstration of the need for early learning in the development of female sociality.     

Local temporal distinctiveness does not benefit auditory verbal and spatial serial recall

In the present study, we examined the role of randomly arranged temporal intervals preceding and following items (pre- and postitem intervals, respectively) in auditory verbal and spatial recall tasks. The duration of the pre- and postitem intervals did not affect serial recall performance. This finding calls into question (1) the suggestion that the interval following an item permits the consolidation of information in memory, even in a relatively demanding spatial task, and (2) the prediction that temporal distinctiveness should improve performance. The latter was explored further by showing that in contrast to our empirical data, a relative temporal distinctiveness model produced significant increases in recall performance when pre- and postitem intervals increased. The results are discussed with regard to recent studies revisiting the role of temporal isolation in short-term serial memory.     

Induction when rats lick for 1% liquid-sucrose reinforcement

Previous research reported that rats responding for 1% liquid-sucrose reinforcement when 32% sucrose reinforcement is upcoming will decrease their response rate (contrast) if licking is the dependent measure and increase their response rate (induction) if pressing a lever is the dependent measure. The present study investigated whether induction could be observed when licking served as the dependent measure and whether induction in lever pressing and contrast in licking behaviour could be concurrently observed. Experiment 1 found induction when rats licked to earn the rewards but consumed them at a location separate from the spout licked to earn them. Experiment 2 also found induction when rats earned (and consumed) rewards by licking the same spout throughout the session. Experiment 3 separately measured instrumental lever pressing for sucrose rewards and licking the sucrose during the reward period. We found that both measures increased for 1% sucrose when 32% sucrose reinforcement was upcoming. The present results indicate that the type of response is not the sole determinant of whether contrast or induction is observed. Rather, they suggest that other procedural details, such as the location of reinforcer delivery, influence which effect is observed. The results also indicate that associative processes underlie the appearance of induction in responding for 1% sucrose.     

Taxonomic Examination of ADHD and Conduct Problem Comorbidity in Elementary School Children Using Cluster Analyses

Cluster analysis was used to investigate the classification of comorbid Attention Deficit Hyperactivity Disorder (ADHD) +Conduct Problems (CP). Teachers rated 1394 elementary school children on symptoms of inattention, hyperactivity/impulsivity, opposition, and conduct problems using the ADS-IV behavior-rating scale. Results suggested that a seven-cluster solution, including two distinct comorbid clusters, was the most appropriate method of classifying children according to behavioral symptoms. A one-way MANOVA showed that overall cluster profiles differed significantly from each other, whereas one-way ANOVAs indicated that clusters differed on age and symptom scores. Chi-square analyses indicated that clusters differed on gender. Post hoc analyses and effect sizes calculations revealed that the comorbid clusters differed from each other and from their single-disorder counterparts on some variables, but not on all. These results provide support for an additive conceptualisation of ADHD +CP.     

Programmatic staff care in an outpatient setting

Traditionally, chaplains have provided care for staff through consultation, informal conversation, grief work, and more formal counsel and ritual. This article discusses four programmatic approaches to staff care created in response to particular assessed needs: "Finding Soul" addresses staff care needs to find meaning and joy in their work and to contribute to the "soul" of the institution. "Existential Expedition" helps staff both deal with their accumulated grief and provide better direct care around existential issues being faced by their patients. "After Book" provides a way for staff to have closure with parents/families and to provide holistic care to families after discharge from the system. "The Labyrinth Program" provides staff with an opportunity to de-stress and to attend to their emotional and spiritual well-being. Focused upon staff care, these programs also secondarily benefit both patients/families and the vision and mission of the institution.     

Posttraumatic stress disorder symptomatology among partners of men in treatment for relationship abuse

This longitudinal study examined posttraumatic stress disorder (PTSD) symptoms among current and former female partners (N = 96) of men participating in a group treatment program for partner abuse perpetrators. Female partner probable PTSD rates, obtained during time points corresponding with pretreatment, posttreatment, and 6-month follow-up for the male clients, were 52%, 34%, and 29%, respectively. Psychological abuse exposure was more strongly and uniquely associated with PTSD symptoms than was physical abuse exposure. Among psychological abuse ratings, denigration, restrictive engulfment, and dominance/intimidation behaviors evidenced the strongest associations with PTSD symptoms. Findings from this study suggest the association between psychological abuse and PTSD is complex and multidetermined.
