Ipsilesional Arm Motor Sequence Performance After Right and Left Hemisphere Damage

Aiming movements are part of daily activities but the brain hemispheres’ role in targeted aiming sequential movements is not fully clear. Start and execution of discrete and sequential tasks toward targets were analyzed in 10 individuals with left-hemisphere damage, 10 right-hemisphere–damaged, and 10 healthy ones. Arm movements were performed over a digitizing tablet, following stimuli on a monitor, from initial position toward right and left-positioned targets. Poststroke individuals used their ipsilesional arm and healthy individuals, both arms. Right-hemisphere–damaged individuals showed higher reaction time and left-hemisphere–damaged individuals, lower smoothness. Due to spatial demand of tasks, the right hemisphere played a major role in movement planning, while the left, in movement execution.     

From One to Two: Can Visual Feedback Improve the Light Touch Effects on Postural Sway?

The postural control is improved by implicit somatosensory information from lightly touching a rigid bar or explicit visual information about the postural sway. Whether these two additional sources provided at the same time further reduce the postural sway is still unknown. Participants stood on a force plate as quiet as possible lightly touching the bar while received or not visual feedback of the center of pressure position on a monitor screen. Postural sway reduced similarly with the light touch regardless of the additional visual feedback. The findings suggested that providing explicit visual feedback of the center of pressure does not increase the light touch effects on the postural sway. The importance of the implicit somatosensory information on postural control is discussed.

Perceptual load does not modulate auditory distractor processing

In vision, it is well established that the perceptual load of a relevant task determines the extent to which irrelevant distractors are processed. Much less research has addressed the effects of perceptual load within hearing. Here, we provide an extensive test using two different perceptual load manipulations, measuring distractor processing through response competition and awareness report. Across four experiments, we consistently failed to find support for the role of perceptual load in auditory selective attention. We therefore propose that the auditory system – although able to selectively focus processing on a relevant stream of sounds – is likely to have surplus capacity to process auditory information from other streams, regardless of the perceptual load in the attended stream. This accords well with the notion of the auditory modality acting as an ‘early-warning’ system as detection of changes in the auditory scene is crucial even when the perceptual demands of the relevant task are high.     

Development and Validation of the Affect in Play Scale–Brief Rating Version (APS–BR)

The concurrence of psychiatric and MMPI based diagnoses for 78 consecutively admitted patients was examined. The results suggest diagnostic coincidence for only 21 of the admitted patients, with the majority being in the differentiation of psychoneurosis from psychosis. Patient sex and chronological age did not appear to be factors in either form of diagnosis.     

Cognition and the Planning Process: An Investigation of Stability of Effects and Decision Makers' Insights

According to Hartman, White, and Crino (1986), planning situations differ in environmental volatility, system adaptation, and the nature of planning requirements, different combinations of which can generate 12 distinct planning situations and 8 information processing aids to be used as planning tools. Each information processing aid has been prescribed to be more appropriate for use in some planning situations than in others (Hartman et al.). In the first part of this study, we tested the hypothesis that a planner in a specific situation would prefer to use the information processing aid(s) prescribed for that situation. We developed 12 different cases and used 456 student subjects. Results indicated that preference did not correspond closely to the Hartman et al. theory but that some other form of implicit theory may be operating. The second part of the research replicated the first part and also examined how 57 subjects viewed their planning problems and weighed the factors involved. Part 2 was also designed to determine the nature of any implicit theory the subjects may have used. Results suggest that the pattern of preferences, although not corresponding to available theory, represents a stable phenomenon.     

The Experimental Delimitation of Neural Structures Essential for Learning: The Attempt to Condition Striped Muscle Responses with Faradization of the Sigmoid Gyri

In looking at motivation as a multifactored trait rather than as a singular trait, a larger portion of the variance in academic achievement is explained. Sixty college students were administered five motivation instruments, each having two components. When the total instruments were used, they explained 23% of the variance, but when they were broken into their component parts, they explained 36%; thus, a schema for approaching motivation as a multifactor trait is presented.     

Evaluation of a Spiritually Based Child Maltreatment Prevention Training Program

The authors empirically evaluated a spiritually based 1‐day child maltreatment training program. Pretest, posttest, and follow‐up results indicated that participants' recognition of hypothetical maltreatment did not increase after training. Furthermore, although participants decreased their use of items known to dissuade decisions to report, they were less likely to report maltreatment posttraining and 1 month later. Focus group data revealed that participants felt more knowledgeable but insufficiently prepared to respond to maltreatment and that they needed opportunities to practice what they had learned. Suggestions for clergy, pastoral counselors, and mental health professionals working within spiritual communities are provided to inform curriculum advancements.     

An innovative group experience for couples expecting their first child

Abstract

This paper presents a pilot project that was developed to work with small groups of couples in which the women were pregnant with their first child. The primary purpose was to stimulate couples to become aware of their communications and support systems as the necessary building blocks for healthy family emotional development. Pregnancy can be seen as a transitional period leading to another life stage in the growth of an individual. The format, topics, evaluation and summary are presented with the hope that other mental health professionals will be motivated to develop similar groups.     

Multi-Couple Group and Self-Directed PREP Formats Enhance Relationship Satisfaction and Improve Anger Management Skills in Air Force Couples

This study examined the effectiveness of delivering the Prevention and Relationship Enhancement Program (PREP) to volunteer couples in the U.S. Air Force in either a six-week instructional multi-couple group condition or a self-directed book condition. A standardized pre/post protocol was employed and outcomes included relationship satisfaction and anger management skills, two known risk factors for partner maltreatment. Significant improvement was found for the group condition in both relationship satisfaction and anger management skills, but only for anger management skills in the self-directed book condition. Finally, the group condition reported greater program satisfaction. Implications are discussed.
