Gender Differences in Supervisors’ Use of Performance Feedback1

This study examined whether male and female supervisors differed in their delivery of performance feedback to subordinates. Male and female subjects supervised 2 confederate subordinates whose performance was stable and either above or below average. Supervisors regularly checked each subordinate's performance and could deliver one of several feedback messages. A MANOVA was performed on frequency of specific negative, general negative, specific positive, general positive, and neutral feedback messages, followed by step down analyses to isolate which dependent variables contributed uniquely. Male and female supervisors were distinguished by their use of specific negative feedback. Males were more likely to provide such messages to poorly performing subordinates, a result consistent with suggestions that males are characterized by a more directive leadership style.     

PARTICIPATION RATES AND MAXIMAL PERFORMANCE:

Abstract— Can the superiority of some countries and groups at certain activities be explained solely by the relative sizes of the participating populations? We focus on the expected highest achievement, max, as a function of the participating group's size For several relevant statistical distributions, max can be shown to be approximately log-linear in sample size, with a slope of about 0 7 SD units We use this relation (max is log-linear ∼0 7 MILL7) to examine differences in performance in chess by men and women and by different countries The expected differences under MILL7 are very close to the observed differences We also examine the implications of MILL7 for the interpretation of other group differences and discuss its limitations     

Triangles in ROC space: History and theory of “nonparametric” measures of sensitivity and response bias

Can accuracy and response bias in two-stimulus, two-response recognition or detection experiments be measured nonparametrically? Pollack and Norman (1964) answered this question affirmatively for sensitivity, Hodos (1970) for bias: Both proposed measures based on triangular areas in receiver-operating characteristic space. Their papers, and especially a paper by Grier (1971) that provided computing formulas for the measures, continue to be heavily cited in a wide range of content areas. In our sample of articles, most authors described triangle-based measures as making fewer assumptions than measures associated with detection theory. However, we show that statistics based on products or ratios of right triangle areas, including a recently proposed bias index and a not-yetproposed but apparently plausible sensitivity index, are consistent with a decision process based on logistic distributions. Even the Pollack and Norman measure, which is based on non-right triangles, is approximately logistic for low values of sensitivity. Simple geometric models for sensitivity and bias are not nonparametric, even if their implications are not acknowledged in the defining publications.     

Psychological stress,work satisfaction,and brain injury nursing

The psychological stress and work satisfaction of two groups of nurses working with clients having brain injuries were assessed and compared with norm groups of people working with other types of injuries and disabilities. Contrary to previously published reports, there was no evidence that the groups in this study were higher on measures of burnout than the selected norm groups. However, work satisfaction was found to be significantly lower for one of the groups when compared not only with the other group but also with the selected norm groups. This lower work satisfaction was associated with significantly lower scores on certain aspects of the work environment when compared with the other group. Results from semi-structured interviews in the study confirmed the importance of the work environment and provided additional information concerning causes of the lower work satisfaction and possible solutions.     

Religiosity, psychoticism, and schizotypal traits

In the present study we investigated the relationship between scores on the Francis Scale of Attitudes towards Christianity [FSAC (Francis & Stubbs, Personality and Individual Differences, 8, 741–743, 1987)], Eysenck's Personality Questionnaire [EPQ (Eysenck & Eysenck, Manual of the Eysenck Personality Questionnaire, 1975)], Eckblad and Chapman's Magical Ideation Scale [MgI (Eckblad & Chapman, Journal of Consulting and Clinical Psychology, 51, 215–225, 1983)], and Claridge's STQ (Claridge & Broks, Personality and Individual Differences, 5, 633–648, 1984). A first Principal Components Analysis with the FSAC and the EPQ confirmed previous work which has shown a negative association between religiosity and psychoticism. A second Principal Components Analysis with all scales yielded a four factor solution:

1. (1) aberrant perceptions and beliefs;

2. (2) social anxiety and suspiciousness;

3. (3) asociality and low religiosity; and

4. (4) social desirability.

Some evidence is also presented for an association between higher religiosity and higher scores on unusual perceptual experiences in men although not in women. Implications for the assessment of religiosity in future research are discussed.     

Perceptual interference at encoding enhances recall for high- but not low-imageability words

Interfering with stimulus perception during encoding can improve later explicit memory (the perceptual-interference effect). The compensatory-processing hypothesis attributes the perceptualinterference effect to enhanced processing of higher level (nonvisual) information during perception. Recent research indicates that the semantic dimension of imageability is one type of higher level information that plays a role in word perception. To the extent that semantic representations play a more important role in the perception of high- than for low-imageability words, the compensatoryprocessing hypothesis predicts a larger perceptual-interference effect for high- than for lowimageability words. Two experiments confirm this prediction. A robust effect of perceptual interference was found for high- but not for low-imageability words.     

Aging and Ethnicity: Issues for Clinical Practice

Due to dramatic improvements in life expectancy among Americans from diverse ethnic groups, the graying of America is resulting in a particularly marked increase in ethnic diversity in late life. Clinicians must be prepared to address the problems of older ethnic minority patients, who present with distinct problems during late life and may present these problems in culturally prescribed ways. Cultural variations in views about the nature of mental disorders, issues in assessing and treating depression and dementia, and attention to issues of family caregivers are deserving of special attention.     

Self-criticism, dependency and the five factor model of personality in depression: assessing construct overlap

The construct overlap between the lower-ordered personality constructs linked to depression, dependency and self-criticism, and higher-ordered personality constructs of the Five Factor Model (FFM) were assessed by exploratory factor analysis in a depressed sample. Three robust factors were extracted: negative affectivity (Neuroticism, Self-Criticism), positive affectivity (Extraversion, Openness), and interpersonal sensitivity (Dependency, Agreeableness). These findings suggest that there is significant construct redundancy between self-criticism and Neuroticism, while dependency appears to represent a more unique dimension associated with, but relatively distinct from Neuroticism and the other dimensions of the FFM.
