NEW LOSS FROM AN OLD PROBLEM: HOW COUNSELORS CAN ASSIST PERSONS WITH POSTPOLIO SYNDROME

For many persons who were diagnosed with polio years ago, late effect symptoms were not anticipated. They believed they had gone through the more severe ramifications of the illness and were unaware that additional problems could occur. Currently, there are hundreds of thousands of persons in the United States who are experiencing significant difficulties with old symptoms and are also developing new physical and emotional difficulties. Unfortunately, little research has looked at the ways counselors can assist this population.Therefore, the purposes of this study were to identify the physical and emotional problems confronting persons with postpolio and to help counselors gain an understanding of issues they feel might be most appropriate to address in therapy sessions.     

Calibration and Alignment are Separable: Evidence From Prism Adaptation

In 2 prism adaptation experiments, the authors investigated the effects of limb starting position visibility (visible or not visible) and visual feedback availability (early or late in target pointing movements). Thirty-two students participated in Experiment 1 and 24 students participated in Experiment 2. Independent of visual feedback availability, constant error was larger and variable error was smaller for target pointing when limb starting position was visible during prism exposure. Independent of limb starting position visibility, aftereffects of prism exposure were determined by visual feedback availability. Those results support the hypothesis that calibration is determined by limb starting position visibility, whereas alignment is determined separately by visual feedback availability.     

Varied Input Stimuli and Motor Learning,

75 apparatus-naive undergraduate Ss were assigned to one of five groups differentiated according to training display associated with a modified rotary pursuit (RP) apparatus. Performance of two control groups, one practicing an unaided reference task and the other a pathmarked RP task, was compared with that of groups that received either path-marked or mechanically guided practice during training, and where path-marked and mechanical guidance display was removed during transfer. It was found that the path-marked display produced superior results only during initial stages of practice, and retarded improvement in performance after transfer to the reference task. Mechanical guidance resulted in better performance on the path-marked condition than the unaided RP task, but in both cases performance dropped upon transfer. The results are discussed in the light of hypothesized learning strategies influenced by different training conditions.     

Johannes Scotus Erigena on Imagination

This study attempted to check, in an authoritarian culture, Ray's hypothesis that there is no relationship between authoritarian behavior and authoritarian attitudes. Scales measuring these two variables were administered to 38 white Afrikaans-speaking South African college men and women (average age 20.74 years). The correlation between the two scales was -.21 which is not significant. The results were therefore seen as a confirmation of Ray's hypothesis.     

Using Score Equating and Measurement Invariance to Examine the Flynn Effect in the Wechsler Adult Intelligence Scale

The Flynn effect (FE; i.e., increase in mean IQ scores over time) is commonly viewed as reflecting population shifts in intelligence, despite the fact that most FE studies have not investigated the assumption of score comparability. Consequently, the extent to which these mean differences in IQ scores reflect population shifts in cognitive abilities versus changes in the instruments used to measure these abilities is unclear. In this study, we used modern psychometric tools to examine the FE. First, we equated raw scores for each common subtest to be on the same scale across instruments. This enabled the combination of scores from all three instruments into one of 13 age groups before converting raw scores into Z scores. Second, using age-based standardized scores for standardization samples, we examined measurement invariance across the second (revised), third, and fourth editions of the Wechsler Adult Intelligence Scale. Results indicate that while scores were equivalent across the third and fourth editions, they were not equivalent across the second and third editions. Results suggest that there is some evidence for an increase in intelligence, but also call into question many published FE findings as presuming the instruments' scores are invariant when this assumption is not warranted.     

Attentional allocation during the perception of scenes

Semantic influences on attention during the 1st fixation on a scene were explored in 3 experiments. Subjects viewed briefly presented scenes; following scene presentation, a spatial probe was presented at the location of an object whose identity was consistent or inconsistent with the scene category. Responses to the probe served as an index of attention. The results of Experiment 1 suggest that within approximately 150 ms of scene onset, subjects attend preferentially to inconsistent objects. The results of Experiment 2, in which additional scene durations were used, confirm the presence of an inconsistent-object advantage that emerges within approximately 150 ms. Finally, the results of Experiment 3 demonstrate that the inconsistent-object advantage does not reflect strategic allocation of attention to likely probe locations. Implications of the results for scene perception and exploration are discussed.     

The Association Between Delirium and Cognitive Decline: A Review of the Empirical Literature

Delirium is a common neurobehavioral syndrome that occurs across health care settings which is associated with adverse outcomes, including death. There are limited data on long-term cognitive outcomes following delirium. This report reviews the literature regarding relationships between delirium and cognitive impairment. Psych Info and Medline searches and investigation of secondary references for all English language articles on delirium and subsequent cognitive impairment were carried out. Nine papers met inclusion criteria and documented cognitive impairment in patients following delirium. Four papers reported greater cognitive impairment among patients with delirium than matched controls. Four papers reported higher incidence of dementia in patients with a history of delirium. One study found 1 of 3 survivors of critical illness with delirium developed cognitive impairment. The evidence suggests a relationship between delirium and cognitive impairment, although significant questions remain regarding the nature of this association. Additional research on delirium-related effects on long-term cognitive outcome is needed.     

Education-stratified base-rate information on discrepancy scores within and between the Wechsler Adult Intelligence Scale--Third Edition and the Wechsler Memory Scale--Third Edition

The Wechsler Adult Intelligence Scale--Third Edition (WAIS-III; D. Wechsler, 1997a) and the Wechsler Memory Scale--Third Edition (WMS-III; D. Wechsler, 1997b) are 2 of the most frequently used measures in psychology and neuropsychology. To facilitate the diagnostic use of these measures in the clinical decision-making process, this article provides information on education-stratified, directional prevalence rates (i.e., base rates) of discrepancy scores between the major index scores for the WAIS-III, the WMS-III, and between the WAIS-III and WMS-III. To illustrate how such base-rate data can be clinically used, this article reviews the relative risk (i.e., odds ratio) of empirically defined "rare" cognitive deficits in 2 of the clinical samples presented in the WAIS-III--WMS-III Technical Manual (The Psychological Corporation, 1997).
