Determining preschoolers' preferences for choice-making opportunities: choice of task versus choice of consequence

Individuals may prefer contexts with the option to choose between 2 reinforcing stimuli or between 2 tasks relative to contexts in which others select the same events. We evaluated children's preferences for conditions characterized by (a) the opportunity to choose between tasks and (b) the opportunity to choose between putative reinforcers delivered following the completion of a task relative to no-choice and no-reinforcement control conditions. Three of 4 participants preferred the consequence-choice condition; the task-choice condition was no more preferred than the no-choice condition in any case.     

Trait Self‐Esteem Moderates the Effect of Initiator Status on Emotional and Cognitive Responses to Romantic Relationship Dissolution

ABSTRACT We hypothesized that the effect of initiator status on post breakup distress would vary as a function of trait self‐esteem, such that individuals with low self‐esteem would experience more distress after being rejected by their partners, whereas, among individuals with high self‐esteem, initiator status would not predict distress. We used a prospective design in which university students (N=66) were assessed for emotional responses following the dissolution of their real‐life romantic relationships, as well as a laboratory design in which students (N=190) imagined breaking up with their partners. As predicted, participants with lower trait self‐esteem exhibited greater distress after experiencing or imagining a romantic rejection than after ending or imagining themselves ending their relationships. Conversely, distress experienced by those with high trait self‐esteem did not differ as a function of who ended the relationship. Implications for understanding self‐esteem processes and the effects of romantic rejection are discussed.     

Development and maintenance of choice in a dynamic environment

Four pigeons were exposed to a concurrent procedure similar to that used by Davison, Baum, and colleagues (e.g., Davison & Baum, 2000, 2006) in which seven components were arranged in a mixed schedule, and each programmed a different left∶right reinforcer ratio (1∶27, 1∶9, 1∶3, 1∶1, 3∶1, 9∶1, 27∶1). Components within each session were presented randomly, lasted for 10 reinforcers each, and were separated by 10-s blackouts. These conditions were in effect for 100 sessions. When data were aggregated over Sessions 16-50, the present results were similar to those reported by Davison, Baum, and colleagues: (a) preference adjusted rapidly (i.e., sensitivity to reinforcement increased) within components; (b) preference for a given alternative increased with successive reinforcers delivered via that alternative (continuations), but was substantially attenuated following a reinforcer on the other alternative (a discontinuation); and (c) food deliveries produced preference pulses (immediate, local, increases in preference for the just-reinforced alternative). The same analyses were conducted across 10-session blocks for Sessions 1-100. In general, the basic structure of choice revealed by analyses of data from Sessions 16-50 was preserved at a smaller level of aggregation (10 sessions), and it developed rapidly (within the first 10 sessions). Some characteristics of choice, however, changed systematically across sessions. For example, effects of successive reinforcers within a component tended to increase across sessions, as did the magnitude and length of the preference pulses. Thus, models of choice under these conditions may need to take into account variations in behavior allocation that are not captured completely when data are aggregated over large numbers of sessions.     

Depression and heart rate variability in cardiac rehabilitation patients: exploring the roles of physical activity and fitness

Cardiac patients with depression have shown altered autonomic nervous system functioning, expressed as reduced heart rate variability. This may be associated with poorer physical fitness and less physical activity among depressed patients. These relationships were explored among patients enrolled in outpatient cardiac rehabilitation. 22 depressed and 22 nondepressed patients, matched for sex and age, were assessed at enrollment. The Beck Depression Inventory and structured interviews were used to measure depression. Patients completed ambulatory monitoring of ECG (i.e., Holter) and physical activity, as well as a treadmill stress test. Depression was associated with several measures of heart rate variability. Activity and fitness were lower among the depressed patients. Although exploratory, accounting for activity and fitness attenuated the relationship between depression and heart rate variability. This suggests that altered fitness and activity may help explain altered autonomic tone that characterizes patients with cardiovascular diseases who are psychologically depressed.     

Adult attachment and feedback‐seeking patterns in relationships and work

Adults with different attachment orientations rely on different areas of life to maintain self‐views. This paper reports two studies that examine the link between attachment and feedback‐seeking patterns in interpersonal and competence‐related domains. Participants in Study 1 imagined receiving feedback from a friend. Participants in Study 2 completed dyadic tasks and were promised feedback from interpersonal‐ and competence‐relevant sources. Across both studies, secure individuals consistently chose the most positive feedback. Individuals high in attachment avoidance sought negative feedback over positive, although dismissing‐avoidant individuals sought positive hypothetical feedback about autonomy. Study 2 further suggested that highly avoidant individuals were more open to negative feedback than positive feedback and than were secure individuals. Moreover, individuals high in attachment anxiety failed to seek positive interpersonal feedback but pursued interpersonal over competence feedback. Results highlight the role of feedback‐seeking in maintenance of positive or negative self‐views for adults with different attachment orientations. Copyright © 2009 John Wiley & Sons, Ltd.     

Direct contact as a moderator of extended contact effects: cross-sectional and longitudinal impact on outgroup attitudes, behavioral intentions, and attitude certainty

Cross-group friendships (the most effective form of direct contact) and extended contact (i.e., knowing ingroup members who have outgroup friends) constitute two of the most important means of improving outgroup attitudes. Using cross-sectional and longitudinal samples from different intergroup contexts, this research demonstrates that extended contact is most effective when individuals live in segregated neighborhoods having only few, or no, direct friendships with outgroup members. Moreover, by including measures of attitudes and behavioral intentions the authors showed the broader impact of these forms of contact, and, by assessing attitude certainty as one dimension of attitude strength, they tested whether extended contact can lead not only to more positive but also to stronger outgroup orientations. Cross-sectional data showed that direct contact was more strongly related to attitude certainty than was extended contact, but longitudinal data showed both forms of contact affected attitude certainty in the long run.     

Gender Differences in the ABC’s of the Birds and the Bees: What Mothers Teach Young Children About Sexuality and Reproduction

Sexuality education is heavily gendered at adolescence. This study uses data from a national web survey of 631 U.S. mothers of 3 to 6 year old children to test whether similar gender differences exist in what mothers teach their young children about sexuality and reproduction. We test (a) whether mothers will report talking more with daughters or sons about sexuality related issues, and (b) whether mothers will report greater comfort talking about such issues with daughters or sons. We find (a) that mothers talk more to daughters than sons about romantic relationships, reproductive bodies, and morality, but not about sexual abuse or intercourse/pleasure. We find (b) mixed results regarding mothers’ comfort in talking with daughters or sons about sexuality.     

Cognitive-Behavior Therapy (CBT) for Panic Disorder: Relationship of Anxiety and Depression Comorbidity with Treatment Outcome

Research evaluating the relationship of comorbidity to treatment outcome for panic disorder has produced mixed results. The current study examined the relationship of comorbid depression and anxiety to treatment outcome in a large-scale, multi-site clinical trial for cognitive-behavior therapy (CBT) for panic disorder. Comorbidity was associated with more severe panic disorder symptoms, although comorbid diagnoses were not associated with treatment response. Comorbid generalized anxiety disorder (GAD) and major depressive disorder (MDD) were not associated with differential improvement on a measure of panic disorder severity, although only rates of comorbid GAD were significantly lower at posttreatment. Treatment responders showed greater reductions on measures of anxiety and depressive symptoms. These data suggest that comorbid anxiety and depression are not an impediment to treatment response, and successful treatment of panic disorder is associated with reductions of comorbid anxiety and depressive symptoms. Implications for treatment specificity and conceptual understandings of comorbidity are discussed.     

Who's Posting Facebook Faux Pas? A Cross‐Cultural Examination of Personality Differences

This study examines culture and personality differences in student reports of the likelihood that they would post various types of information on their Facebook profiles. As predicted those high on conscientiousness, agreeableness, and emotional stability proved significantly less likely to report posting problematic content (e.g., substance abuse, sexual content) on their profile. Those who scored high on Compulsive Internet Use indicated a greater likelihood to post such profile information. Consistent with our expectations, our cross‐cultural analysis revealed that US students were more inclined than German students to post problematic information to their Facebook site. Implications of these results and recommendations for future research are discussed.     

Art Therapy as a Healing Tool for Sub-fertile Women

Although fertility is fundamental to spiritual health, it is often taken for granted. When a desired pregnancy fails to occur, stress and grief frequently follow. Visual expression of feelings through “art therapy” has proved a powerful healing tool for women brave enough to give it a try at the McMaster University Fertility Clinic. The objective and subjective findings of this ongoing project suggest that through simple visual self-expression, stress, anxiety and hopelessness may be reduced. This form of art therapy also provides a joyful social experience of sharing with other women, who are dealing with these issues.
