Extratest validity of selected personality assessment inventory scales and indicators in an inpatient substance abuse setting

The purpose of this study was to extend previous findings regarding the extratest validity of the Personality Assessment Inventory (Morey, 1991, 2007) scales and indicators in forensic contexts to an inpatient substance abuse setting. The Aggression Scale, and particularly the Physical Aggression subscale, related to assault history; the Suicide Scale and Suicide Probability Index related to history of suicide attempts; Antisocial Features, and particularly the Antisocial Behaviors subscale, predicted rule infractions; and the Treatment Process Index predicted treatment completion. We discuss clinical implications in the context of extant findings.     

Collaboration reduces the frequency of false memories in older and younger adults

Older (mean age = 74.23) and younger (mean age = 33.50) participants recalled items from 6 briefly exposed household scenes either alone or with their spouses. Collaborative recall was compared with the pooled, nonredundant recall of spouses remembering alone (nominal groups). The authors examined hits, self-generated false memories, and false memories produced by another person's (actually a computer program's) misleading recollections. Older adults reported fewer hits and more self-generated false memories than younger adults. Relative to nominal groups, older and younger collaborating groups reported fewer hits and fewer self-generated false memories. Collaboration also reduced older people's computer-initiated false memories. The memory conversations in the collaborative groups were analyzed for evidence that collaboration inhibits the production of errors and/or promotes quality control processes that detect and eliminate errors. Only older adults inhibited the production of wrong answers, but both age groups eliminated errors during their discussions. The partners played an important role in helping rememberers discard false memories in older and younger couples. The results support the use of collaboration to reduce false recall in both younger and older adults.     

College students who wear watches: locus of control and motivational sources

119 undergraduate college students were administered the Rotter I-E Scale and the Motivation Sources Inventory. Scores were compared for a group of 66 students who were wearing watches and 53 students who were not wearing watches. The former had higher scores on External locus of control and higher scores on a measure of Instrumental Motivation as anticipated.     

Quality of life and social support of patients being evaluated for bone marrow transplantation

A sample of 437 patients completed self-report measures of quality of life and social support while they were being evaluated for bone marrow transplantation (BMT) at The Johns Hopkins Oncology Center. Generally, the candidates showed reasonably high levels of quality of life (QOL) on the Satisfaction with Life Domains Scale (SLDS), their present ranking on the Cantril Self-Anchoring Ladder of Life, and their scores on the Bradburn Positive Affect Scale. The level of QOL of these candidates for transplant was significantly related to their level of social support. Both availability and adequacy of social support for these transplant candidates were found to be significantly related to QOL as measured by the SLDS. Availability of social support as measured by patient membership in religious and other organizations was significantly related to Positive Affect but not Negative Affect. The Family APGAR and Relational Support Scales measures of social support were significantly correlated with both Positive and Negative Affect.

Posture and the emergence of manual skills

In this paper, we examine how infants’ natural manual and postural activities — what they prefer and do week by week — are related to developmental transitions in reaching skill and its neuromuscular control. Using a dense, longitudinal design, we tracked the manual and postural activities of four infants in a natural, free‐play setting across the first year of life, and related these activities to two transitions in reaching as measured in a structured laboratory setting: the transition to reaching and the transition to stable reaching. Our data indicated that specific advances in the free‐play setting preceded both transitions. Head and upper torso control, the ability to extend the arm and hand to a distant target, and the ability to touch and grasp objects placed nearby were all precursors to the onset of reaching, whereas sitting independently was associated with the transition to stable reaching. We also found important individual variability in when these ‘components’ were in place, indicating that it is the ensemble of components that is essential, not the order in which they develop or the timing of their contribution. These findings suggest that subsequent experimental manipulations should be planned with respect to infants’ individual constellations of skills, rather than looking at only a single precursor to change.     

Prediction and control as determinants of behavioural uncertainty: Effects on task performance and heart rate reactivity

Control or control-belief is often viewed as being directly instrumental in facilitating coping mechanisms in aversive situations, and yet the empirical evidence for the beneficial effects of control is inconclusive. In this study we investigated the role of predictability in determining the effects of perceived control during an aversive reaction time task. Fifty-six subjects were allocated to one of four groups; predictable-control, predictable-no control, unpredictable-control, unpredictable-no control. In the predictable conditions, subjects could temporally predict the occurrence of an aversive noise. In the perceived control conditions, duration of the aversive tone was contingent on subject’s performance. All subjects were matched in terms of the nature of the task and in the number and time of receipt of both the warning signal and noise. Heart rate reactivity and two performance parameters were measured, reaction time and performance increase. Both predictability and control-belief led to a reduction in heart rate reactivity, although they appeared to function independently and at different points in the sequence of events. That is, predictability or perceived control was sufficient to mitigate the effects, of an aversive situation. Neither perception of control or predictability led to better task performance. These results are discussed in terms of behavioural uncertainty explanations.
