Effects of symptom presentation order on perceived disease risk

People are quick to perceive meaningful patterns in the co-occurrence of events. We report two studies exploring the effects of streaks in symptom checklists on perceived personal disease risk. In the context of these studies, a streak is a sequence of consecutive items on a list that share the characteristic of being either general or specific. We identify a psychological mechanism underlying the effect of streaks in a list of symptoms and show that the effect of streaks on perceived risk varies with the length of the symptom list. Our findings reveal a tendency to infer meaning from streaks in medical and health decision making. Participants perceived a higher personal risk of having an illness when presented with a checklist in which common symptoms were grouped together than when presented with a checklist in which these same symptoms were separated by rare symptoms. This research demonstrates that something as arbitrary as the order in which symptoms are presented in a checklist can affect perceived risk of disease.     

The relationship between sex role stereotypes and requisite management characteristics among college students

The relationship between sex role stereotypes and characteristics perceived as necessary for management success was examined among male and female undergraduate management students and compared with results of managers today as well as with those of managers studied 15 years ago. Male management students, similar to their managerial counterparts in the 1980s and 1970s, still adhere to the male managerial stereotype and perceive that successful middle managers possess characteristics, attitudes, and temperaments more commonly ascribed to men in general than to women in general. Female management students, similar to today's female managers, no longer sex type the managerial job, a change from the female managers of the 1970s. Implications of these outcomes for undergraduate management education are discussed.Portions of this research were funded by a Gettysburg College Institutional Self Renewal Grant.     

Yale Children's Inventory (YCI): An instrument to assess children with attentional deficits and learning disabilities I. Scale development and psychometric properties

The Yale Children's Inventory (YCI), a parent based rating scale, and the scales derived from it have been developed to identify and measure multiple dimensions of learning disabilities with particular emphasis on attentional deficits. Scale construction was based on factor analytic procedures. Measures of internal consistency, test retest reliability, and coefficients of congruence support the reliability and stability of the 11 scales. A discriminant function classified normal and learning disabled children with a relatively high rate of accuracy. The relationship and content of the three relevant YCI scales were compared to the DSM-III diagnostic categories for ADD. As operationalized, DSM-III criteria for hyperactivity formed a cohesive factor, while criteria for attention and impulsivity were not distinguishable from each other since they loaded together on a single factor. In contrast, the equivalent YCI scales for attention, impulsivity, and hyperactivity were found to be distinct.     

The child custody evaluation: Issues and trends

Custody disputes are often the crisis point in the divorcing process and the numbers of contested custody cases are increasing. Mental health professionals are being called upon to provide evaluations of these families more frequently than ever. This article focuses on how to perform child custody evaluations. It touches on the highly troublesome cases where accusations of abuse and alcoholism have been made, and how to convey to attorneys the findings of an evaluation. It begins by reviewing developments in child custody law and concludes by addressing the problems between behavioral sciences and the law in these stressful cases. The presentation of clinical examples provides a view of the decision making process, while addressing the contextual setting for these cases as well.     

THE TRANSCENDENT FUNCTION OF THE BILATERAL BRAIN

Abstract. A "transcendent function," which integrates conscious and unconscious elements, can be characterized for the human mind. From Carl Jung's model of four basic functions of the psyche—thinking, feeling, sensation, and intuition—a modified compass of the psyche is constructed to conform to the neurobio-logical structure of the bilateral brain. The transcendent function can be correlated with the principal states of consciousness existent between waking and sleep. Dreams, myth, and the experience of deity, of related unconscious content, are manifest in hybrid states of consciousness. The exercise of the transcendent function is of creative value in the arts and sciences and paramount to human survival.     

Stress and blood glucose in type II diabetes mellitus

Six adults with non-insulin dependent diabetes mellitus participated in a laboratory procedure to determine the effects of an acute Stressor, mental arithmetic, on blood glucose, cardiovascular, and subjective indices of stress. They then completed 12 days home monitoring of stressful events, subjective stress, and blood glucose. Diet and activity were controlled to evaluate the direct effects of stress on blood glucose in the natural environment. Laboratory results showed significant increases in blood glucose, cardiovascular (HR and SBP), and subjective stress ratings during the mental arithmetic task when compared to a resting condition. Home monitoring data were consistent with the laboratory findings; blood glucose range tended to be greater on high vs low stress days, especially when the difference between high and low stress was greatest. These findings suggest that the laboratory stress induction procedure was externally valid and that in the natural environment, stress has a hyperglycemic effect on blood glucose.     

Supraspan verbal memory in attention deficit disorder with hyperactivity normal and reading-disabled boys

To assess memory problems associated with attention deficit disorder with hyperactivity (ADDH) and reading disability (RD), nonverbal subspan, span, and supraspan measures was administered to 30 ADDH, 30 normal, and 24 RD boys, ages 7 to 12. Results from the supraspan verbal measures, which included word lists and related and unrelated paired associates, are reported. Across all verbal tasks, deficits became most apparent in ADDH boys on measures requiring organized, deliberate rehearsal strategies, sustained strategic effort, and careful consideration of response alternatives. This pattern suggests impaired self-regulatory or executive processes. RDs showed more generalized deficits across the verbal measures, suggesting problems with verbal processing. Recent studies supporting this interpretation are reviewed.This research was partially supported by Grant MA-6913 from the Medical Research Council of Canada.

A multicomponent investigation of the interaction of generalized anxiety and phobia

Forty female undergraduates forming four groups, high or low trait anxiety with or without a specific fear (rats), participated in a psychophysiological assessment of their response to the phobic object, a neutral object (rabbit), and to a general anxiety-induction procedure (threat of shock). Subjects also completed a number of tasks requiring sustained attention. Blood samples were drawn to determine thyroid hormone (T3 and T4) levels. Trait anxiety was found to interact with specific fear in response to the feared object. The high-trait anxious/high-fear group was most physiologically responsive to the rat. Trait- anxious subjects were more responsive to the threat of shock and showed performance deficits on reaction time, vigilance, and backward digit span tasks. These subjects also had significantly higher T3 and T4 levels. The findings are discussed with regard to the role of general anxiety in the etiology and/or maintenance of specific fears and the role of thyroid hormones in accentuating physiological response to feared stimuli.     

Short-term serial recall in ADDH,normal, and reading-disabled boys

Short-term retention of verbal items of span and subspan length was examined in hyperactive (ADDH), normal and non-ADDH reading-disabled boys. Performance of ADDH and normal boys did not differ on three measures of verbal serial recall. Thus, it appears that the cognitive deficits of ADDH children cannot be attributed to deficient retention of stimuli. In contrast, reading-disabled (RD) boys performed significantly more poorly than both normal and ADDH boys when required to recall verbal items following filled delay intervals in which the children were required to perform a competing verbal activity. The results suggest that verbal encoding of RD children is particularly vulnerable to interference from other verbal stimuli. ADDH and RD children may represent subsamples of children demonstrating academic difficulties, with each group showing a characteristic pattern of cognitive deficits.This article is based on a doctoral dissertation submitted to the Faculty of Graduate Studies and Research of McGill University.

The attributional response of males and females to noncontingent feedback

The attributions of male and female college student subjects following exposure to noncontingent, contingent, and no-feedback conditions were analyzed in a 2×3 multivariate analysis of variance. The experimental hypothesis was that exposure to noncontingent feedback would result in more depressive attributions than exposure to contingent feedback or to no feedback, and that this effect would be moderated by gender. The hypothesis was partially supported in that females receiving noncontingent feedback on a concept discrimination problem subsequently made more internal attributions for negative events than male subjects receiving noncontingent feedback and female subjects receiving contingent feedback or no feedback.
