Emotional speech processing: Disentangling the effects of prosody and semantic cues

To inform how emotions in speech are implicitly processed and registered in memory, we compared how emotional prosody, emotional semantics, and both cues in tandem prime decisions about conjoined emotional faces. Fifty-two participants rendered facial affect decisions (Pell, 2005a), indicating whether a target face represented an emotion (happiness or sadness) or not (a facial grimace), after passively listening to happy, sad, or neutral prime utterances. Emotional information from primes was conveyed by: (1) prosody only; (2) semantic cues only; or (3) combined prosody and semantic cues. Results indicated that prosody, semantics, and combined prosody–semantic cues facilitate emotional decisions about target faces in an emotion-congruent manner. However, the magnitude of priming did not vary across tasks. Our findings highlight that emotional meanings of prosody and semantic cues are systematically registered during speech processing, but with similar effects on associative knowledge about emotions, which is presumably shared by prosody, semantics, and faces.     

Cognitive mediation of intervention effects on physical exercise: Causal models for the adoption and maintenance stage

Objective: To investigate how the effects of a group-based intervention program (MoVo-LISA) on exercise behaviour were mediated by cognitive variables. Different causal models mapping the short-term (adoption) and long-term (maintenance) intervention effects were tested using path analyses.

Design: N?=?220 in-patients of a rehabilitation clinic were assigned to an usual care or intervention group (quasi-experimental design). Questionnaire-based assessment was conducted at baseline; discharge; and at six weeks, six months and 12 months post discharge.

Measures: The potential mediator variables were outcome expectations, self-efficacy, strength of goal intention (intention strength), self-concordance, action planning and barrier management.

Results: Observed intervention effects on exercise behaviour (p?<?0.05) were mediated by intention strength at the adoption and maintenance stages, by action planning only at the adoption, and by barrier management only at the maintenance stage. Self-efficacy and outcome expectations were only indirectly involved in these mediations by affecting intention strength and self-concordance.

Conclusion: This is the first study to track the cognitive mediation processes of intervention effects on exercise behaviour over a long time-period by differentiating the adoption and maintenance stages of behaviour change. The findings emphasise the importance of deconstructing intervention effects (modifiability vs. predictive power of a mediator) to develop more effective interventions.     

Response-dependent point loss and response force as disrupting operations on behavioral resistance to change in humans

Behavioral momentum theory (BMT) provides a theoretical and methodological framework for understanding how differentially maintained operant responding resists disruption. A common way to test operant resistance involves contingencies with suppressive effects, such as extinction or prefeeding. Other contingencies with known suppressive effects, such as response-cost procedures arranged as point-loss or increases in response force, remain untested as disruptive events within the BMT framework. In the present set of three experiments, responding of humans was maintained by point accumulation programmed according to a multiple variable-interval (VI) VI schedule with different reinforcement rates in either of two components. Subsequently, subtracting a point following each response (Experiment 1) or increasing the force required for the response to be registered (Experiments 2 and 3 decreased response rates, but responding was less disrupted in the component associated with the higher reinforcement rate. The point-loss contingency and increased response force similarly affected response rates by suppressing responding and human persistence, replicating previous findings with humans and nonhuman animals when other types of disruptive events (e.g., extinction and prefeeding) were investigated. The present findings moreover extend the generality of the effects of reinforcement rate on persistence, and thus BMT, extending the analysis of resistance to two well-known manipulations used to reduce responding in the experimental analysis of behavior.     

Spiritual Maturity and Meaning-Filled Relationships: A Sociological Perspective

SUMMARY

The process of self-development, spiritual maturity and the construction of new meaning-filled relationships in late life are analyzed through the actions and interactions observed in the biographical case history of Sarah-Patton Boyle. Atchley's four stages in the process of retirement applied to the case of Sarah-Patton Boyle identifies the changes in her social roles and relationships and the struggle to maintain a positive self-view in the midst of socio-environmental changes. The struggle to continue “spiritual self” identity and ties with the church are discussed.     

Brief strategic therapy in first myocardial infarction patients with increased levels of stress: a randomized clinical trial

Background: Little is known about the impact of interventions targeting chronic stress levels on clinical outcomes among myocardial infarction (MI) patients with increased levels of stress. Objectives: To examine the impact of the addition of brief strategic therapy (BST) to usual care (UC) on clinical outcomes in first MI patients with increased levels of stress. Design: Eighty-one patients were randomly assigned to BST in conjunction with UC (medical treatment, risk factor information, and guidance on unhealthy behavior change) or to UC. Methods: The outcome measures were scores on the Perceived Stress Scale, reinfarction and cardiac mortality rates, and scores on the Health Survey. Measures were taken before, post-treatment, and at two follow-ups. Results: Patients subjected to BST showed reduced perceived stress at post-treatment and maintained decreased levels at follow-ups. At 1-year follow-up, they had a lower rate of non-fatal reinfarction, and at 2.5-year follow-up, they had a lower rate of fatal reinfarction. Their mental and physical health was improved at post-treatment and this was sustained at follow-ups. Conclusion: The addition of BST to UC favorably influences the disease course after MI in patients with increased levels of stress.     

Interpretive bias,repressive coping,and trait anxiety

Objectives: According to vigilance–avoidance theory, repressors have an avoidant interpretive bias, i.e., they interpret ambiguous self-relevant situations in a nonthreatening fashion. This study sought to demarcate the range of situations associated with avoidant interpretive bias in repressors. Design: Four groups of participants, representing the four combinations of low- and high-trait anxiety and defensiveness, were identified. Those low in trait anxiety and high in defensiveness were categorized as repressors. Methods: Participants (N = 163) rated their likelihood of making both threatening and nonthreatening interpretations of 32 ambiguous scenarios over four domains: social, intellectual, physical, and health. Half the scenarios were self-relevant and half were other relevant. Brief measures of state anxiety were taken after each likelihood rating. Results: Repressors displayed an avoidant interpretive bias for ambiguous threats in the social and intellectual domains but not the health or physical domains. This was due to repressors' low level of trait anxiety rather than their high defensiveness. Conclusions: Individuals high in trait anxiety are especially sensitive to situations involving social evaluation but not those characterized by danger to their health or physical well-being.     

Autobiographical Memory Disturbances in Childhood Abuse Survivors

Summary

Clinicians have noted that childhood abuse survivors frequently report that they have forgotten large parts of their childhood. While memory for abusive experiences has attracted a great deal of attention from researchers, other types of memory disturbances may also accompany a history of childhood trauma. Many clinicians report that certain types of sexual abuse, and abuse at certain developmental stages, is more likely to result in reports of gaps in memory for the abuse. However, because information has been mainly collected in clinical populations, the possibility of confounding between abusive experiences and psychological disturbances cannot be ruled out. This article reports on data gathered from a large, epidemiologic study conducted within a health maintenance organization. A history of childhood physical or sexual abuse doubled the prevalence of general autobiographical memory loss for women, while for men, the rate increased 1.5 times over those with no abuse history. Higher rates of autobiographical memory loss were noted where both types of abuse were reported. Further, multiple incidents of sexual abuse, sexual abuse by a relative, and more severe sexual abuse increased reports of autobiographical memory loss. Theoretical perspectives on changes in the memory system that may affect trauma survivors are discussed.     

Experimental and Self-Reported Indices of Childhood Abuse Using the Binghamton Childhood Abuse Screen

This study describes the validation of the Binghamton Childhood Abuse Screen (BCAS) using response latencies on an emotional Stroop task as a criterion measure. Sixty-four male undergraduate participants were selected based on their responses to the BCAS and a brief screen of their abuse history. Participants completed an emotional Stroop task in which they named the colors of neutral, positive, and abuse words. Participants scoring high on the BCAS exhibited greater response latencies to abuse words than participants scoring low on the BCAS. No group differences were found for positive words. The results provide support for the validity of the BCAS.     

Linking Childhood Maltreatment to Substance Use in College Students: The Mediating Role of Self-Worth Contingencies

This study investigated the link between childhood maltreatment and substance use, focusing on examining contingencies of self-worth (CSWs) as mediators among college students (N?=?513). Structural equation modeling indicated that childhood sexual abuse among females was related to lower God's love CSW, which in turn was related to higher levels of cigarette, marijuana, and other illicit drug use, supporting the mediational role of God's love CSW. Correlational analyses demonstrated that, for both male and female students, external contingency of appearance was related to higher substance use, whereas internal contingencies of God's love and virtue were related to lower substance use. The findings highlight the protective role of internal CSWs in substance use among females with childhood sexual abuse.
