Matching Messages to Motives in Persuasion: A Functional Approach to Promoting Volunteerism1

This study examined a functional strategy for investigating audience responses to motivationally-based persuasive appeals. It was predicted that people exposed to advertisements informing them how they could satisfy personally relevant motivations through volunteering (i.e., functionally matched messages) would judge these ads to be more persuasive, more emotionally positive, and would report being more likely to volunteer than people exposed to advertisements unrelated to their personally relevant motivations (i.e., functionally mismatched messages). These predictions were confirmed in an experiment wherein participants whose attitudes toward volunteerism served a Social Adjustive, Value Expressive, Utilitarian, Knowledge, or Ego Defensive function viewed advertisements promoting volunteerism that either matched or mismatched their personally relevant motivations. Results confirmed predictions as participants responded more favorably to the functionally matched than mismatched messages. The implications of this research for understanding the mechanisms by which functionally matched messages exert persuasive influence and the ramifications of the research for the practice of volunteerism are discussed.     

Family Interdependence,Spiritual Perspective,Self-Transcendence,and Depression Among Korean College Students

The purpose of this study was to examine the mechanisms that might account for the effects of spirituality and self-transcendence on Korean college students’ depression among 197 Korean fathers, mothers, and children. A structural equation analysis indicated that spiritual perspective related to lower depression through the mediating pathway of self-transcendence for individuals. Mothers’ spiritual perspective and self-transcendence related to their children’s depression through the mediating pathway of their own depression, but the same was not true for fathers. Findings help explicate the intergenerational transmission of depression and important predictors of depression related to spirituality.     

Microinfusion of the D1 receptor antagonist, SCH23390 into the IL but not the BLA impairs consolidation of extinction of auditory fear conditioning

In auditory fear conditioning, repeated presentation of the tone in the absence of the shock leads to extinction of the acquired fear response. Both the medial prefrontal cortex (mPFC) and the basolateral amygdala (BLA) are involved in extinction. Here we examined this involvement by antagonizing D1 receptors in both regions, in the rat. We microinfused the D1 receptor antagonist, SCH23390, into the infra-limbic part of the mPFC (IL) or BLA at different time points. SCH23390 mircoinfused into the IL either before extinction acquisition or following short extinction training resulted in impairment of extinction consolidation. Microinfusion of SCH23390 into the BLA, prior to acquisition of extinction caused impairment in acquisition of extinction without affecting extinction consolidation. This is supported by the results showing that microinfusion of SCH23390 into the BLA following a short-training session did not affect consolidation. These results further strengthen the role of mPFC in consolidation of extinction while highlighting the role of the D1 receptors in this process.     

Protoalgebraic Gentzen Systems and the Cut Rule

In this paper we show that, in Gentzen systems, there is a close relation between two of the main characters in algebraic logic and proof theory respectively: protoalgebraicity and the cut rule. We give certain conditions under which a Gentzen system is protoalgebraic if and only if it possesses the cut rule. To obtain this equivalence, we limit our discussion to what we call regular sequent calculi, which are those comprising some of the structural rules and some logical rules, in a sense we make precise. We note that this restricted set of rules includes all the usual rules in the literature. We also stress the difference between the case of two-sided sequents and the case of many-sided sequents, in which more conditions are needed.     

Learning reward expectations in honeybees

The aim of this study was to test whether honeybees develop reward expectations. In our experiment, bees first learned to associate colors with a sugar reward in a setting closely resembling a natural foraging situation. We then evaluated whether and how the sequence of the animals’ experiences with different reward magnitudes changed their later behavior in the absence of reinforcement and within an otherwise similar context. We found that the bees that had experienced increasing reward magnitudes during training assigned more time to flower inspection 24 and 48 h after training. Our design and behavioral measurements allowed us to uncouple the signal learning and the nutritional aspects of foraging from the effects of subjective reward values. We thus found that the animals behaved differently neither because they had more strongly associated the related predicting signals nor because they were fed more or faster. Our results document for the first time that honeybees develop long-term expectations of reward; these expectations can guide their foraging behavior after a relatively long pause and in the absence of reinforcement, and further experiments will aim toward an elucidation of the neural mechanisms involved in this form of learning.     

Skills Practice in Dialectical Behavior Therapy for Suicidal Women Meeting Criteria for Borderline Personality Disorder

Dialectical Behavior Therapy (DBT) is an evidence-based practice for borderline personality disorder (BPD) and suicidal behavior that has been replicated with a variety of populations. Patients’ practice of behavioral skills taught in the group skills training component of DBT may be partly responsible for the positive treatment outcomes according to the skills deficit model of BPD that underlies DBT. This study was designed to examine the type and frequency of skills practiced by DBT patients. Participants were 49 women, who met criteria for BPD and current and chronic suicidal behavior, receiving 1 year of standard DBT as part of a clinical trial. Skills were recorded on the daily diary cards completed by participants each week and reviewed by their individual therapists. Results indicated that the majority of participants reported practicing skills most days throughout treatment. Crisis survival and mindfulness skills were practiced most frequently in our sample. Hierarchical linear modeling demonstrated that skills practice increased as a function of time in therapy. Directions for future research are discussed.     

Anger and time perception in children

The present study investigated age-related variations in judgments of the duration of angry facial expressions compared with neutral facial expressions. Children aged 3, 5, and 8 years were tested on a temporal bisection task using angry and neutral female faces. Results revealed that, in all age groups, children judged the duration of angry faces to be longer than that of neutral faces. Findings are discussed in the framework of internal clock models and the adaptive function of emotion.     

Parental Efficacy Moderates the Association Between Empathy and Burden Among Parents of Children Admitted to a Psychiatric Ward

Empathy is considered a positive aspect of caregiving, although in certain circumstances, being empathic might increase the burden of caregivers. The current study assessed the associations between empathy, parental efficacy, and family burden among parents of children who were hospitalized in a psychiatric unit. Specifically, we examined whether the association between empathy and family burden was moderated by the parents’ sense of self-efficacy. Seventy parents of children with psychiatric disorders, hospitalized in an inpatient psychiatric unit, filled out questionnaires of empathy, parental efficacy, and family burden. Results supported a moderating role of parental efficacy between empathy and family burden (interaction effect: β = −1.72, p = .0406). Specifically, empathy was positively related to family burden among parents with low self-efficacy (conditional effect = 0.70, p = .032) and negatively related to family burden among parents with high self-efficacy (conditional effect = −0.39, p = N.S). Implications for practice include the importance of self-efficacy and address the possible negative implications of empathy among parents of children treated in a psychiatric hospital.
