A behavioral link between the oculomotor and cardiovascular systems

Although the eyes and the heart serve very different purposes, each receives autonomic innervation. Capitalizing on recent theoretical and technological innovations in the understanding and assessment of oculomotor and cardiovascular behavior, three experiments measured behavioral covariation between the oculomotor and cardiovascular systems. Measures of dark focus and dark vergence indexed oculomotor tone, and the spectral decomposition of variations in heart rate indexed cardiovascular control mechanisms. In Experiment 1, individual differences in cardiovascular parameters could predict individuals’ dark vergence (R²=.806) but not their dark focus (R²=.404). In Experiment 2, the same parameters were measured from subjects who experience either panic attacks (n=11) or blood phobia (n=9). Heart rate was positively correlated with dark vergence and the two subject groups were separable based on both oculomotor and cardiovascular variables. Using a within-subjects approach, Experiment 3 found that both dark vergence and dark focus tended to be nearer during sympathetic dominance of the heart than during parasympathetic dominance, within-subjects variations in cardiovascular parameters could predict dark focus, and between-subjects variations in interbeat intervals could predict dark vergence. Shared patterns of autonomic activation may be responsible for this eye-heart link.     

The use of consultation in psychological practice: ethical, legal, and clinical considerations

The importance of consulting with other professionals to maintain acceptable standards of care is well documented in many health care professions. However, evidence indicates that many psychologists fail to utilize consultation when needed, and that consultation use varies along dimensions such as the education and training of the consultee, the type of setting, number of years in practice, and proximity to available consultants. In this article, we review the research on the use of consultation by psychologists as well as other health care professionals. We discuss the clinical, ethical, and legal implications of seeking consultation as a professional psychologist. Finally, a detailed and practical model for the regular use of consultation is given to improve the routine use of consultation in clinical practice.     

Racial Categorization and Stereotype-Based Judgments About Homeless People1

The present study uses a social-cognitive paradigm to examine the association between racial categorization and stereotype-based judgments about homeless people. The study uses data from a national White subsample (N= 1,221) surveyed about attitudes toward homeless/homeless mentally ill people. It was hypothesized that individual differences in perceptions of the representativeness of Blacks in the homeless population, as measured by subjective estimates of the percentage of Blacks, would be associated with the enhancement of racially relevant negative stereotypes about homeless people. A secondary hypothesis was that perceptions of the representativeness of Blacks would be more strongly associated with the stereotype of homeless people as dangerous than with the view of them as lazy. The results support these hypotheses.     

Physician-assisted suicide: the role of mental health professionals

A review of the literature was conducted to better understand the (potential) role of mental health professionals in physician-assisted suicide. Numerous studies indicate that depression is one of the most commonly encountered psychiatric illnesses in primary care settings. Yet, depression consistently goes undetected and undiagnosed by nonpsychiatrically trained primary care physicians. Noting the well-studied link between depression and suicide, it is necessary to question giving sole responsibility of assisting patients in making end-of-life treatment decisions to these physicians. Unfortunately, the use of mental health consultation by these physicians is not a common occurrence. Greater involvement of mental health professionals in this emerging and debated area is advocated. Beyond describing mental health professionals' role in the assessment of patient competency or decision making capacity, other areas of potential involvement are described. A discussion of ethical principles relevant to this area follows, along with comments on the training necessary to adequately serve patient needs.     

Richard L. Solomon and learned helplessness

This article reviews the course of development of research on a currently popular explanatory approach to dysfunctional behavior, the learned helplessness analysis. The early history is prominent in this review as it reflects the inspirations of Richard L. Solomon, a scholar who fostered the resurgence of psychologists’ interests in Pavlovian conditioning in the 1950s and 1960s. Current research is characterized as having four separate themes: elaboration of “symptoms,” elucidating the role of fear, explicit modeling, and extensions involving attributional constructs.     

Microprocessors in the laboratory: Dedicated computation and time-shared peripherals with REMOTE-11

This article describes a new solution to the dilemma faced by investigators who need dedicated computers but cannot afford the cost of expensive peripherals. An available software-hardware combination is described that permits users to timeshare expensive peripherals but to have a dedicated microprocessor at their disposal.
