Spatial coupling affects both homologous and non-homologous limbs

The present study examined the interaction between limb movements in space. The amount of interaction was measured by how much moving one limb affected the movement of another limb. Participants were 24 right-handed university students (19 female, mean age=19 years). The task was to draw lines with the right hand while moving another limb in lines or circles of different sizes. Significant coupling effects were found between both homologous and non-homologous limbs. Movement of the right hand was most strongly affected by the left hand, less by the right foot, and least by the left foot, consistent with the functional cerebral distance model. This effect of limb was observed only in the major dimension along which movement was not restrained. Both the limb and dimension effects were reduced when the trajectory of motion decreased in size.     

The impact of frontal and non-frontal brain tumor lesions on Wisconsin Card Sorting Test performance

Several lesion and imaging studies have suggested that the Wisconsin Card Sorting Test (WCST) is a measure of executive dysfunction. However, some studies have reported that this measure has poor anatomical specificity because patients with either frontal or non-frontal focal lesions exhibit similar performance. This study examined 25 frontal, 20 non-frontal low-grade brain tumor patients, and 63 normal controls (NC) on the WCST. The frontal patients were also assigned to either a left frontal (n=10) group or a right frontal group (n=15) and compared with the non-frontal group and NC. It was hypothesized that the frontal brain tumor patients would display greater deficits on categories achieved and a higher number of perseverative errors than non-frontal brain tumor patients on the WCST. Finally, it was predicted that right frontal brain tumors would result in greater executive functioning deficits than left frontal or non-frontal brain tumors. Results indicated that the left frontal group achieved the fewest categories and committed the most perseverative errors compared to the other patient and normal control groups. In addition, the left frontal group committed significantly more perseverative errors than the right frontal group. These results suggest that the WCST is sensitive to the effects of low-grade brain tumors on executive functioning.     

The role of age and perceptual symbols in language comprehension

Older and younger participants read sentences about objects and were then shown a picture of an object that either matched or mismatched the implied shape of the object in the sentence. Participants' response times were recorded when they judged whether the object had been mentioned in the sentence. Responses were faster in the shape-matching condition for all participants, but the mismatch effect was stronger for older than for younger adults, even when the larger variability of the older group's response times was controlled for. These results suggest that older adults may construct stronger situation models than younger adults.     

Employee Eldercare Responsibilities: Should Organizations Care?

The question "Should organizations be concerned with the eldercare responsibilities of their employees?" was addressed from several perspectives: (1) prevalence of need, (2) the relationships among eldercare responsibilities, satisfaction with eldercare arrangements, and workplace attitudes and outcomes, and (3) support for organizational eldercare programs. Our sample was predominately female and we defined eldercare responsibilities broadly; however, only 5 of 885 employees reported eldercare responsibilities. The majority relied on family arrangements and reported dissatisfaction with these arrangements. Dissatisfaction was related to interruptions at work, leaving early, and intent to quit. Eldercare-givers did not differ from other groups on job satisfaction and organizational commitment, but were absent from work significantly more often. There was strong employee support for employer-sponsored eldercare programs.     

Ethnic differences in battered women's formal help-seeking strategies: a focus on health, mental health, and spirituality

The primary goal of this study was to identify ethnic differences in battered women's use of health, mental health, and spiritual coping strategies, as well as differences in the perceived helpfulness of each strategy. The authors recruited a sample of 376 African American and Caucasian victims of interpersonal violence from various sites. In comparison with Caucasian women in the sample, African American women were significantly more likely to report using prayer as a coping strategy and significantly less likely to seek help from mental health counselors. The 2 groups did not significantly differ in terms of the extent to which they sought help from clergy or medical professionals. African American women found prayer to be more helpful than did Caucasian women.     

Research,policy, and the federal role in prevention initiatives for children

With the ability and the funds to implement programs on a national level, federal policy is a potentially potent tool in primary prevention. Despite the U.S. government's history of ambivalence toward intervening in child rearing and limited national support for primary prevention, several initiatives have been implemented for children and families with some measure of success. The successes, however, are mitigated by limitations of the initiatives themselves and by the inconclusive nature of much of the evaluation data. This review of 5 federal policy-based initiatives for children and families provides the backdrop for discussing aspects of federal prevention program design, implementation, policy, and research.     

A multisite comparison of actuarial risk instruments for sex offenders

Four actuarial instruments for the prediction of violent and sexual reoffending (the Violence Risk Appraisal Guide [VRAG], Sex Offender Risk Appraisal Guide [SORAG], Rapid Risk Assessment for Sex Offender Recidivism [RRASOR] and Static-99) were evaluated in 4 samples of sex offenders (N = 396). Although all 4 instruments predicted violent (including sexual) recidivism and recidivism known to be sexually motivated, areas under the receiver operating characteristic (ROC) were consistently higher for the VRAG and the SORAG. The instruments performed better when there were fewer missing items and follow-up time was fixed, with an ROC area up to .84 for the VRAG, for example, under such favorable conditions. Predictive accuracy was higher for child molesters than for rapists, especially for the Static-99 and the RRASOR. Consistent with past research, survival analyses revealed that those offenders high in both psychopathy and sexual deviance were an especially high-risk group.     

Adult attachment,the transition to parenthood,and depressive symptoms

Testing a model suggested by J. Bowlby (1988), this study investigated how a personal vulnerability (attachment ambivalence) interacts with perceptions of deficient spousal support before and during a major life stressor (the transition to parenthood) to predict pre-to-postnatal increases in depressive symptoms. Highly ambivalent women who entered parenthood perceiving either less support or greater anger from their husbands experienced pre-to-postnatal increases in depressive symptoms at 6 months postpartum. The associations between these 2 prenatal interaction terms and pre-to-postnatal increases in depressive symptoms were mediated by perceptions of declining spousal support across the transition period. Moreover, for highly ambivalent women, the association between prenatal and postnatal depression scores was mediated by perceptions of the amount of support available from their husbands.     

Mood regulation and emotional intelligence: individual differences

In 3 studies (Ns = 250, 83, 236), an examination of differences in how individuals experience their emotions (meta-emotion traits of clarity, attention, and intensity) led to the identification of 4 distinct types (overwhelmed, hot, cerebral, and cool). When mood was manipulated, the types differed in how they initially reacted to the emotional situation, how they regulated their mood, and how they made judgments. In particular, one type of individual (the hot type) was more reactive to emotional situations than the others. Another type of individual (the overwhelmed type) regulated mood differently than the others, which led these individuals to make judgments that were also different. Overwhelmed individuals appeared unable or unwilling to avail themselves of critical affective information.     

Exploring the influence of personality on depressive symptoms and self-esteem across a significant life transition

This study investigates the influence of personality on adjustment to a particular life transition, community relocation. Participants were 285 women (average age=69.5) who were interviewed once before they moved, and then multiple times after the move. Within the context of this multiwave design, personality traits were used to predict changes in depressive symptoms (DS) and self-esteem (SE) across the move. Neuroticism and Openness to Experience predicted increases in DS over time, whereas Extraversion and Openness predicted increases in SE. Stressful reactions to the move and sense of mastery about the move partially mediated these effects. The study documents the dynamic influence of personality on positive and negative aspects of adjustment and investigates differing routes through which such effects occur.
