Threats to the Operational Use of Situational Judgment Tests in the College Admission Process

This study examined the coachability of two situational judgment tests, the College Student Questionnaire (CSQ) and the Situational Judgment Inventory (SJI), developed for consideration as selection instruments in the college admission process. Strategies for raising scores on each test were generated, and undergraduates were trained in the use of the strategies using a video‐based training program. Results indicated that the CSQ was susceptible to coaching. In addition, the scoring format of the CSQ was found to be easily exploited, such that trainees could increase their scores by greater than 1 SD simply by avoiding extreme responses on that test. The results as a whole sounded a note of caution for the potential use of the CSQ in the college admission process.     

Linking Biomechanical Workload and Organizational Practices to Burnout and Satisfaction

We found support for several hypotheses linking work practices to employee outcomes: reducing biomechanical workload is associated with decreased burnout via perceptions that job demands are less threatening; lower demands are associated with higher job satisfaction primarily through decreases in burnout; employers who include employees in decision making processes have employees with lower levels of burnout and higher satisfaction; and having a disability management program is associated with having employees who report less job-related burnout. This study demonstrates the importance of programs that increase perceived organizational support and the importance of job design strategies that take into account physical workload.     

Sex-specific clinical correlates of hoarding in obsessive-compulsive disorder

Little is known about whether the clinical correlates of hoarding behavior are different in men and women with obsessive-compulsive disorder (OCD). In the current study, we evaluated the association of hoarding with categories of obsessions and compulsions, psychiatric disorders, personality dimensions, and other clinical characteristics separately in 151 men and 358 women with OCD who were examined during the OCD Collaborative Genetics Study. We found that, among men but not women, hoarding was associated with aggressive, sexual, and religious obsessions and checking compulsions. In men, hoarding was associated with generalized anxiety disorder and tics whereas, among women, hoarding was associated with social phobia, post-traumatic stress disorder, body dysmorphic disorder, nail biting, and skin picking. In women but not men, hoarding was associated with schizotypal and dependent personality disorder dimensions, and with low conscientiousness. These findings indicate that specific clinical correlates of hoarding in OCD are different in men and women and may reflect sex-specific differences in the course, expression, and/or etiology of hoarding behavior in OCD.     

Prevalence and correlates of hoarding behavior in a community-based sample

Little is known about the prevalence and correlates of hoarding behavior in the community. We estimated the prevalence and evaluated correlates of hoarding in 742 participants in the Hopkins Epidemiology of Personality Disorder Study. The prevalence of hoarding was nearly 4% (5.3%, weighted) and was greater in older than younger age groups, greater in men than women, and inversely related to household income. Hoarding was associated with alcohol dependence; paranoid, schizotypal, avoidant, and obsessive-compulsive personality disorder traits; insecurity from home break-ins and excessive physical discipline before 16 years of age; and parental psychopathology. These findings suggest that hoarding may be relatively prevalent and that alcohol dependence, personality disorder traits, and specific childhood adversities are associated with hoarding in the community.     

Sex-role orientation as related to psychological and physiological responses during achievement and orthostatic stress

The Bem sex-role inventory was used to select, from an Irish student population, females and males who differed with regard to feminine and masculine personality characteristics. Four groups were established for each sex: (1) subjects with low scores in both femininity and masculinity, i.e., undifferentiated subjects; (2) subjects with high scores in both femininity and masculinity, i.e., androgynous subjects; (3) subjects with high scores in femininity and low scores in masculinity; (4) subjects with high scores in masculinity and low scores in femininity. The Cattell 16 PF scale showed that the undifferentiated groups were more reserved and detached and more cautious and taciturn than the androgynous groups. Each subject was exposed to mental stress in one session and orthostatic stress in another session. Mental stress was induced by five different intellectual performance tests. Males and females differed significantly only on a test of perceptual speed, with females performing better than males, as expected. The group of androgynous females was superior to all other groups on four of the five performance tasks. The group of androgynous males was not superior in terms of objective performance but reported feeling more confident andThis collaboration was made possible by a twinning grant to Dr. John Cullen and Professor Marianne Frankenhaeuser from the European Training Programme in Brain and Behaviour Research, European Science Foundation. Financial support was also obtained by grants from the Swedish Medical Research Council (Project No. 997) and the Swedish Council for Research in the Humanities and Social Sciences. satisfied with their performance than most other groups, particularly the undifferentiated males. Blood pressure and heart rate were significantly elevated in all groups during both stress conditions. Heart rate was significantly higher in the high-femininity and androgynous females than in the other female groups.     

Codependency: An Empirical Study from a Systemic Perspective

To empirically investigate the construct validity of codependency, differences between young adults on a measure of codependency on theoretically relevant variables were examined. Compared with individuals who scored low on codependency, those who obtained high scores reported significantly more family of origin difficulties and parental mental health problems, problematic intimate relationships including relationships with chemically dependent partners, and personal psychological problems including compulsivity. Contrary to prevailing theoretical predictions the high codependency group did not contain more individuals whose parents had alcohol or drug abuse problems, or a higher level of childhood physical or sexual abuse. These results suggest that co-dependency is one aspect of wider multigenerational family systems problems which are not unique to families where drug and alcohol abuse or physical and sexual abuse are major concerns.     

Jury simulation studies: To exclude or not to exclude participants based on a lack of comprehension of the case?

Jury simulation research has been the subject of longstanding criticism in regards to ecological validity. One additional factor that has received little attention that may also impact the generalizability of this research relates to excluding participants based on their memory of, or their attention paid to, the case. In order to determine how common this exclusion is, the authors conducted a scoping review of jury simulation studies within the last 10 years across three major legal psychology journals. The review revealed variability in if and how studies excluded on the basis of poor attention or for failing manipulation or general memory checks. In addition, studies that did exclude on this basis varied greatly in the proportion of the sample that was excluded. Recommendations are provided in order to assist jury researchers in future with how best to manage exclusions on the basis of juror memory and attention.     

Studies on sensory feedback: III the effects of display gain on tracking performance

Instrumentation is described which permits study of the effects of different forms of visual feedback display on the patterns of fine movement obtained from the extended human index finger when the subject is attempting to keep his finger at a fixed point in space. The task is a compensatory tracking task in which the only source of input to the system is the subject's own finger movement. The effects of increasing the gain (or amplification) of a proportional error signal on the pattern of finger movement was studied. Gains of 1, 2, 4, 10, 20 and 40 were studied with a group of 24 subjects. Increasing the gain of a proportional error signal resulted in a marked improvement in the ability of subjects to maintain their extended finger at a fixed point in space. As the gain of the error signal was increased, the subject's high-amplitude, low frequency errors were reduced, and there was a progressive appearance of high-frequency activity of low-amplitude, more accurately centred about the reference position in space. A total off-target area measure (integrated absolute error) showed marked decrease in scores as the amplification of the error signal was increased from 1 through 10. Beyond this gain there was no appreciable additional improvement in motor control, however no degradation of control was noted to characterize the group performance.

Exploratory studies were undertaken to permit comparison of the effects of increasing the gain of a proportional visual display with the effects of increasing the gain of non-proportional visual and auditory displays. An increase in the dominant-energy frequency was noted as the error signal gain was increased, independent of whether a proportional visual, or non-proportional visual or auditory display was used. This observation suggests that common mechanisms mediate the processing of the gain parameters of feedback displays, in some measure independent of the display form or the sensory modality used for presentation.
