Cerebral laterality and depression: differences in perceptual asymmetry among diagnostic subtypes

Examined the influence of diagnostic subtype of depression on perceptual asymmetry for dichotic listening and visual tachistoscopic tasks. A total of 65 unmedicated patients with major depressive disorders and 30 normal controls were tested on a verbal and nonverbal task in each modality. Patients diagnosed according to the DSM-III with melancholia had abnormal perceptual asymmetry for dichotic nonsense syllable and complex tone tasks. In contrast, patients having a nonmelancholic "atypical depression" (reactivity of mood with preserved pleasure capacity and associated features) did not differ from normal controls on these tasks, but had an increased incidence of left handedness. Bipolar depression (history of hypomania) differed from unipolar depression in showing abnormal perceptual asymmetry for a tachistoscopic dot enumeration task. Alterations of perceptual asymmetry in melancholia and bipolar depression were consistent with hypothesized right hemisphere dysfunction.     

Family Functioning of Male Alcoholics and Their Female Partners during Periods of Drinking and Abstinence

Family functioning of 20 alcoholic male veterans and their female partners was assessed in relation to drinking (wet) and abstinent (dry) intervals. Repeated measures analyses performed on the McMaster Family Assessment Device (FAD) indicated that on all 7 scales of the FAD, alcoholics and their mates perceived family functioning to be better during dry than wet periods. In contrast to their alcoholic mates, female partners gave healthier ratings to all FAD scales except Roles in the dry condition and Affective Involvement in the wet condition. According to published cutoff scores for healthy and unhealthy family functioning, alcoholics as a group viewed their wet and dry family functioning as unhealthy, although the female group regarded the family's dry Problem Solving and Behavioral Control as healthy. These findings suggest that the family functioning of alcohol-involved couples is biphasic, oscillating between drinking and abstinent periods.     

Standardizing the administration of the Profile of Mood States (POMS): development of alternative word lists

Although standard administration procedures are essential for valid inference making, current Profile and Mood States (POMS; McNair, Lorr, & Droppleman, 1971) protocol forces each examiner, when asked for assistance, to provide subjects extemporaneously with a word or phase that is: (a) synonymous with the original item, (b) located nowhere else on the instrument, and (c) more meaningful to the subject than the original item. The purpose of this article is to describe an empirically based extension of current POMS protocol designed to augment uniformity in administration procedures by providing examiners with a standardized list of alternatives to be referred to when questions concerning the meaning of POMS items arise. A multiphase survey procedure was employed to generate and refine alternative items. A series of alpha (internal consistency) reliabilities, calculated for the POMS subscales after each alternative was substituted, revealed little change in subscale homogeneity resulting from the substitution of the alternatives.     

Cardiovascular reactivity and interpersonal influence: active coping in a social context

Previous studies have demonstrated that effortful attempts to secure positive outcomes or avoid negative outcomes produce significant increases in systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR). Although these effects of active coping on cardiovascular reactivity are central in current psychosomatic theories, virtually all of the research to date has used impersonal, asocial tasks. Our two studies examined the cardiovascular effects of effortful attempts to influence other people. In Study 1, male subjects attempting to influence the opinions of their discussion partner to improve their own chances of winning money displayed significantly greater SBP, DBP, and HR reactivity. In Study 2, we obtained similar effects on SBP and DBP reactivity in men and women, while both preparing an influence attempt and making that attempt. Furthermore, reactivity levels were larger as the magnitude of incentive for successful persuasion increased. Implications of this interpersonal equivalent of active coping for the development of cardiovascular disease are discussed.     

Psychometric properties of Loevinger's Sentence Completion Test in an adult psychiatric outpatient sample

Little research has been conducted on Loevinger's Washington University Sentence Completion Test of Ego Development in adult psychiatric outpatients. The measure is a promising method of assessing a construct of personality and character functioning that should be useful in research on psychopathology and in choosing treatment modalities. The data presented in this study address the question of the psychometric adequacy of the measure in this segment of the subject population. Specifically, estimates of interrater reliability, internal consistency, and test-retest reliability are presented for a sample of 42 adult outpatients. In addition, the relationship between total protocol ratings and item sum scores is explored.     

Psychological test signs of borderline personality disorder: a review of the empirical literature

Recent empirical work aimed at identifying test signs of borderline personality disorder is reviewed. The review focuses on commonly employed clinical tests, including the Wechsler Adult Intelligence Scale (WAIS), the Rorschach, and the Minnesota Multiphasic Personality Inventory (MMPI). Possible test signs are considered in relation to their sensitivity to and specificity for the diagnosis and in relation to the criteria of DSM-III, which define the disorder. Although consistent patterns of potentially useful test signs have begun to appear, methodological difficulties have hampered any subsequent development of clinically useful indices. Greater attention to sample size and its composition and definition as well as demonstrations of adequate reliability and predictive utility are required for further development of these signs.     

Inferring Emotions From Multiple Cues: Revealing Age-Related Differences in "How" Without Differences in "Can"

This study examined differences in children's use of social cues to make emotional inferences. Children ages 4, 5, and 8 years were presented with stimuli that depicted another child in affectively congruous and affectively incongruous expression/situation combinations. The intensity of positive and negative facial expressions was varied across situations. Subjects judged the target's feelings and selected among the alternative facial expressions or situations the one they had just seen. No significant age-related differences were found in the extent to which children registered and used both the expressive and situational information when making emotional inferences. The main experimental measure asked children to explain their judgments. In explaining their judgments, subjects' rationales indicated that they: (a) used both the situational and expressive cues; and (b) were sensitive to congruous versus incongruous cues, and even to mild versus strong incongruous cues. Children's rationales also reflected a sensitivity to expressive and situational negativity. For each age group, the rationales were more elaborate when the cues were problematic. Characteristic strategies, however, were also found for each age group. These distinct strategies may reflect social-life changes in children's social "theories" of emotion.     

The role of propulsive muscles of the shoulder during quadrupedalism in vervet monkeys (Cercopithecus aethiops): implications for neural control of locomotion in primates

In comparative anatomical studies of the shoulder, the humeral retractors are often grouped together as propulsive muscles, which are important in the propulsive stroke of the forelimb during quadrupedal locomotion. Electromyographic (EMG) analyses of these muscles in opossums, cats, and dogs in general have confirmed such conclusions. An EMG study of chimpanzee shoulder muscles during knuckle-walking found, however, that the humeral retractors are either inactive or perform a function unrelated to propulsion (Larson & Stern, 1987). This contrast in muscle recruitment patterns between chimpanzees and more "typical" mammalian quadrupeds was attributed to the derived morphology of the chimpanzee shoulder. The present study examines the activity patterns of the humeral retractors in the vervet monkey, a primate more closely resembling nonprimate mammals in its shoulder morphology. The results of this EMG analysis show that despite the significant differences in anatomy between chimpanzees and vervets, the two species display very similar muscle recruitment patterns during quadrupedalism, and there is evidence for this same pattern in other species of primates. These differences in muscle activity patterns between primates and nonprimate mammals may be related to changes in the neurological control of locomotion in primates due to the evolutionary development of manipulative abilities in the primate forelimb.     

A Test of Bipolar and Androgyny Perspectives of Masculinity and Femininity: The Effect of Participation in an Outward Bound Program

ABSTRACT The purposes of the present investigation are to examine theoretical issues in androgyny theory by testing the effect of participation in the Outward Bound program on measures of masculinity (M) and femininity (F) Bipolar conceptualizations of MF posit that an increase in either M or F must lead to a decrease in the other, whereas androgyny theory posits M and F to be independent constructs Consistent with a priori predictions based on the nature of the Outward Bound program, participation substantially enhanced M and had a small positive effect on F The results were reasonably consistent for male and female participants, for single-sex and mixed-sex groups, and across responses to three different MF measures Results support the androgyny interpretation of MF and demonstrate the effectiveness of the Outward Bound program in changing MF The results contradict the bipolar perspective that an increase in M must be accompanied by a decrease in F
