Type A behavior, job satisfaction, and stress among black professionals.

Most studies of work-related Type A behavior have been conducted with samples of white men. Using a mail questionnaire to assess Type A behavior, job satisfaction, and daily stress and tension among 250 black men and 233 black women public accountants, the prevalence of Type A behavior and its relationship with satisfaction and stress were highly consistent with those reported for other samples of white men and women.     

Manifestability and Semantic Realism

Abstract: This paper provides a critical discussion of Alexander Miller's recent attack on antirealist arguments against semantic realism that are based on manifestability requirements. Miller attempts to defend semantic realism against Wright-Hale arguments from manifestability. He does so in reliance on a McDowell type assertion-truth platitude. This paper argues in both general terms and in relation to the details of Miller's argument, that attempts to defend semantic realism while accepting a Dummettian-Wittgensteinian framework on theories of meaning, are misconceived and likely to fail, as I believe is true in Miller's case. Semantic realism is best defended within a context of metaphysical realism, and naturalistic-causal theories of meaning and explanation.     

Emotional states alter force control during a feedback occluded motor task

The aim of the current experiment was to determine the extent to which pleasant and unpleasant emotional states altered the ability of men and women to control force production on a feedback occluded motor task that was not direction specific. Participants produced a precision pinch grip with visual feedback. After 5 s, feedback was occluded and replaced with a pleasant, unpleasant, or neutral image. The amplitude, variability, and structure of force production were calculated. As expected, the removal of visual feedback led to progressive force decay. More important, relative to neutral conditions, pleasant and unpleasant emotional states led to greater force production, resulting in attenuated force decay. The variability and structure of force production were not altered by affective state. In addition, men and women performed similarly across all conditions for all measures. We conclude that when sustained force production is not directed toward or away from the body, pleasant and unpleasant emotional states similarly excite the motor system. Neurobiological mechanisms are proposed to account for these findings. Implications and future research directions are discussed.     

Learning the value of money from stochastically varying prices

In 3 experiments, the authors investigated learning of the value of money from product prices in an unfamiliar currency when the prices are proportional to quantity. In support of the second stage of a hypothesized 2-stage process of learning, Experiment 1, in which 32 undergraduates participated, shows that response times for inferences of quantity are longer when participants are presented with quantity-price pairs than when they are presented with price-quantity pairs. Experiments 2 and 3, in which 54 and 34 undergraduates participated, respectively, show that (a) stochastic price variation causes systematic errors in the learning of unit prices from quantity-price pairs as a result of judgmental regression effects and (b) in support of the 2-stage learning hypothesis, inferences of quantity are the inverse of the learned unit prices.     

Ethical issues in exercise psychology

Exercise psychology encompasses the disciplines of psychiatry, clinical and counseling psychology, health promotion, and the movement sciences. This emerging field involves diverse mental health issues, theories, and general information related to physical activity and exercise. Numerous research investigations across the past 20 years have shown both physical and psychological benefits from physical activity and exercise. Exercise psychology offers many opportunities for growth while positively influencing the mental and physical health of individuals, communities, and society. However, the exercise psychology literature has not addressed ethical issues or dilemmas faced by mental health professionals providing exercise psychology services. This initial discussion of ethical issues in exercise psychology is an important step in continuing to move the field forward. Specifically, this article will address the emergence of exercise psychology and current health behaviors and offer an overview of ethics and ethical issues, education/training and professional competency, cultural and ethnic diversity, multiple-role relationships and conflicts of interest, dependency issues, confidentiality and recording keeping, and advertisement and self-promotion.     

Family Emotional Climate and Sibling Relationship Quality: Influences on Behavioral Problems and Adaptation in Preschool-Aged Children

We examined the impact of family emotional climate and sibling relationship quality on behavioral problems and adaptation in preschool-aged children. Participants were 63 mothers with a preschool-aged child enrolled in a Southern Arizona Head Start Program. Siblings were identified as children closest in age to target child. Mothers of predominantly Mexican descent (95%) participated in home interviews during the Fall and Spring of the year children entered center-based programs. Sibling relationship quality (warmth, agonism/competition) was proposed to predict children’s adjustment (behavioral problems and adaptation) longitudinally. Results indicate that after controlling for child characteristics (temperament, child gender, birth order) and after accounting for family characteristics (family emotional expressiveness, child exposure to interparental conflict, and parental agreement on childrearing), sibling warmth made a significant and unique contribution to child adjustment as reported by mothers and teachers six months later. Findings are consistent with existing research indicating that sibling relationships impact children’s adjustment and shape young children’s lives in meaningful and marked ways. Moreover, these associations were found with an understudied sample of young children of predominantly Mexican descent in low-income families, and thus make an important contribution to knowledge in the field.     

Characteristics of memories for traumatic and nontraumatic birth

Evidence for memory characteristic differences between trauma and other memories in non‐clinical samples is inconsistent. However, trauma is frequently confounded with the event recalled. This study compares trauma and nontrauma memories for the same event, childbirth, in a non‐clinical sample of 285 women 4–6 weeks after birth. None of the women met diagnostic criteria for post‐traumatic stress disorder. Traumatic birth, defined by the DSM‐5 event criterion, was reported by 100 women. The ratings of some memory characteristics did not differ between memories for traumatic and nontraumatic birth: All were rated highly coherent and central to women's lives, with moderate sensory memory. However, women who experienced traumatic births reported more involuntary recall, reliving, and negative/mixed emotions. Thus, trauma memories differed from nontrauma memories. In this non‐clinical sample, this is likely to be due to encoding during trauma rather than the distinctive memory profile for memories retrieved by those experiencing trauma symptoms.
