Depressive personality: reliability, validity, and relation to dysthymia

The reliability and validity of Schneider's (1958) construct of depressive personality was evaluated in a sample of 177 outpatients, who were administered structured diagnostic and family history interviews, an extensive battery of inventories, and a 6-month follow-up assessment. The criteria for depressive personality had moderate to good interrater reliability, internal consistency, and test-retest stability, and the assessment of depressive personality traits was not influenced by patients' clinical states. In addition, preliminary support for the convergent and discriminant validity of the depressive personality construct was obtained. Although there were significant relations between the depressive personality and Diagnostic and Statistical Manual of Mental Disorders (3rd ed. and rev. 3rd ed.; American Psychiatric Association, 1980, 1987) diagnoses of dysthymia, the depressive personality was not entirely subsumed by existing mood disorders.     

Letter identification declines with increasing retinal eccentricity at the same rate for normal and dyslexic readers

It has recently been claimed (Geiger & Lettvin, 1987; Perry, Dember, Warm, & Sacks, 1989) that the acuity/eccentricity function is flatter in dyslexics than in normal subjects, with dyslexics showing better performance in the periphery and worse performance at fixation. In these studies, all target letters were presented to the right of fixation, a procedural flaw inviting subjects to optimize performance by directing attention and/or gaze to the right of the designated fixation point. It is suggested that dyslexic and normal readers may differ in the degree to which they might adopt the optimal strategy in this situation. To overcome this problem, target letters were briefly presented at 16 randomly intermixed locations derived from the orthogonal combination of four eccentricities and four directions from fixation (above, below, right, left). The accuracy of letter identification declined with increasing eccentricity at the same rate for good and poor adult readers and dyslexic teenagers. This finding provides no support for the view that the acuity/eccentricity function might vary with and possibly cause differences in reading level.     

MATERNITY LEAVE AND WOMEN'S MENTAL HEALTH

The Wisconsin Maternity Leave and Health Study addresses an important policy issue, parental leave, by investigating the work status, maternity leave, and mental health of 570 women. In the longitudinal design, the women, all of whom were living with a husband or partner, were interviewed during the fifth month of pregnancy, 1 month postpartum, and 4 months postpartum. At 4 months postpartum, full-time workers, part-time workers, and homemakers did not differ in depression or anger, but full-time workers showed elevated anxiety compared with the other two groups. In multiple regression analyses, length of leave interacted significantly with marital concerns when predicting depression; women who took a short leave (6 weeks or less) and were high on marital concerns had the highest depression scores. Short maternity leave can be conceptualized as a risk factor that, when combined with other risk factors such as marital concerns, places women at greater risk for depression.     

Differentiation of brain damage among low IQ subjects with three projective techniques.

Using a battery of three projective techniques (Rorschach, Hand Test, Bender-Gestalt) only slight discrimination was found between low IQ subjects classified according to the presence or absence of brain trauma (exogenous vs endogenous), while substantial discrimination was obtained between the same subjects categorized in terms of "lower" (60-74) and "higher" (75-89) FS WAIS IQ. All four groups used in this study had been first equated on sex and age. Results were interpreted as supporting the position that some sort of brain impairment underlies most or all retardation. Question was raised concerning the efficacy of projective techniques for diagnosing organicity in subjects of average or better intelligence.     

Gender typing of game choices and qualities of boys' play behavior

Relationships between gender choices and both movement patterns and social behavior were studied in first- and second-grade boys. Three-child, structured play groups were each composed of a boy whose mother saw him as high masculine in play preference on the Games Inventory, one seen as average, and one low masculine. Behaviors rated from videotapes included gender presentation variables, (e.g., leg separation), indicators of dominance and personal comfort (e.g.,range of movements), and indicators of social skill and peer response (e.g., interaction initiations). The low masculine boys were found to be the most feminine in their gender presentation, least dominant and aggressive, and the least socially successful of the boys. The greatest difference was between the low and the high masculine boys. The average masculine boys' scores were generally intermediate,but more similar to the low masculine boys on some variables and more similar to the high masculine boys on others. These conclusions apply to a group interaction play task, but not to an initial noninteractive play task. A secondary study in which girls played with low and average masculine boys is also reported. Here it was found that low masculine boys were generally intermediate between average boys and girls on gender presentation and dominance variables, but lowest of the groups on social interaction variables. The authors appreciate the comments of Peter Bentler and Spencer Thompson on a draft of this paper, the assistance of Laura McCain in running subjects and scoring tapes, and the expertise of Shu-Yeng Wong for computer programming.     

The computer psychiatrist: How far have we come? Where are we heading? How far dare we go?

The use of computers in psychiatry and psychology is reviewed. It is noted that computers are already being used successfully for consultation, interviewing, and continuing education. Issues related to the usage of computers in mental health are discussed. Guidelines for future work in the area are suggested.     

The effect of uncertainty on the detection of frequency modulation at low modulation rates

Frequency modulation detection performance is compared in two conditions of stimulus variability. The data show that when the modulation rate is randomized within an experimental block, performance is somewhat poorer than when the modulation rate is fixed. The results are interpreted within the framework of a template matching model for modulation detection. They suggest that a template is acquired in part from experimental context and in part from a multistage template matching process.     

Evidence for the Altruistic Personality from Data on Accident Research

ABSTRACT The aim of this study was to test whether the concept of an altruistic personality was valid for first aiders who intervened to help the victims of a traffic accident. We derived a number of relevant personality variables that should be related to the willingness to administer first aid. These include locus of control, social responsibility, belief in a just world, empathy, and instrumentality. We obtained data from proven first aiders who had intervened after a traffic accident. Thirty-four of these first aiders were matched to respondents from a subject pool on the basis of sex, age, and socioeconomic status. In addition, the willingness of these respondents to offer help after a traffic accident was taken into account. Only people who indicated that they had witnessed an accident and had not helped were included in the control group. Multivariate analyses of variance and covariance indicated that proven first aiders deviated from the control group on several dimensions: They described themselves as more internal, believed more in a just world, and emphasized more social responsibility and empathy.     

Combining shape and position expectancies: hierarchical processing and selective inhibition.

Two experiments report the effects of generating a concurrent position expectancy and form expectancy. Ss were precued to a stimulus position where 1 target shape was most probable, and they made a speeded 2-choice response to the orientation of the displayed shape. Response time (RT) was faster for an expected position than an unexpected position and faster for a likely shape than for an unlikely shape. This replicates the work of Lambert and Hockey (1986). It was also observed, however, that when a stimulus appeared at an unexpected position where 2 shapes were equally improbable, RT was slower for the shape that had been likely rather than unlikely at the cued position. This finding is incompatible with the probability-matching hypothesis of Lambert and Hockey. The data support a hierarchical-expectancy model of attentional selectivity.
