Negative reactions to received spousal care: predictors and consequences of miscarried support.

This study focused on the negative reactions of older women with osteoarthritis to the receipt of instrumental support (i.e., physical assistance) from their husbands and the effects of such negative reactions on the women's psychological well-being and self-care. Applying a person-environment fit model, the authors predicted that women's negative reactions to spousal support would be determined by the fit between this support and the personal centrality (importance) of being functionally independent. Consistent with this prediction, women who received high levels of support from the husband and for whom being functionally independent was not highly central reacted less negatively to this support. More negative reactions to spousal support were related to greater concurrent depressive symptomatology and fewer self-care behaviors. In addition, negative reactions were predictive of the women's increased depressive symptomatology and decreased life satisfaction. Findings illustrate a useful theoretical approach to the examination of support from family caregivers.     

Distraction intervention for preschoolers undergoing intramuscular injections and subcutaneous port access.

This study evaluated a distraction intervention designed to reduce the distress of preschool children undergoing repeated chemotherapy injections. Twenty-nine children aged 2-5 years were randomly assigned either to distraction by a developmentally appropriate electronic toy or to a wait-list control. Children who received the distraction intervention demonstrated lower overt behavioral distress and were rated by parents and nurses as less anxious than children in the control condition. The improvements were maintained over the 8-week intervention. The results suggest that a developmentally appropriate, multisensory, variable-distracting activity that requires active cognitive processing and active motor responses may be a viable cost-effective alternative to more time-intensive parent-training programs for preschool-age children.     

Examining the effects of frustration on working memory capacity

The present study attempts to expand our understanding of frustration, clinical symptoms, and working memory by examining the unique contribution of attention-deficit/hyperactivity disorder symptoms and frustration to working memory capacity (WMC). A factor-analytic framework was utilized to isolate and examine WMC based on results from three working memory tasks that were administered in counterbalanced order to control for individual differences in baseline WMC. All participants provided subjective ratings of frustration both prior to and after administration of a frustration induction. Results suggest that although we were able to systematically induce subjective frustration for participants in the experimental group relative to the control group, WMC was not associated with induced frustration in the present study. Results also indicated that inattention symptoms predicted baseline frustration levels. This work highlights the need to examine the extent to which storage/rehearsal WMC and additional process-oriented working memory-related performance variables are related to frustration. The data that support the findings of this study are available from the corresponding author upon request.     

An information-motivation-behavioral skills model of adherence to antiretroviral therapy.

HIV-positive persons who do not maintain consistently high levels of adherence to often complex and toxic highly active antiretroviral therapy (HAART) regimens may experience therapeutic failure and deterioration of health status and may develop multidrug-resistant HIV that can be transmitted to uninfected others. The current analysis conceptualizes social and psychological determinants of adherence to HAART among HIV-positive individuals. The authors propose an information-motivation-behavioral skills (IMB) model of HAART adherence that assumes that adherence-related information, motivation, and behavioral skills are fundamental determinants of adherence to HAART. According to the model, adherence-related information and motivation work through adherence-related behavioral skills to affect adherence to HAART. Empirical support for the IMB model of adherence is presented, and its application in adherence-promotion intervention efforts is discussed.     

On some worldly worries

Israel Scheffler and others have had trouble accepting such drastic theses in my work as that worlds, even old ones, are made by right versions, even new ones, and that two conflicting versions may both be right. But further explication shows how such theses have advantages over the more usual common-sense alternatives.Published by the author at Emerson Hall, Harvard University, Cambridge, Massachusetts, 02138, U.S.A., on 1 September 1988.NOTICE: This paper may be copied and circulated with due credit but without charge.

Further analysis of encoding in patients with Huntington's disease

Arguments favoring the view that derangement of normal encoding processes contributes to the memory defects of patients with Huntington's disease (HD) are supported by the finding that HD patients do not learn highly imageable words more rapidly than they learn words that are difficult to image. But other data indicating that HD patients can use verbal mediators as mnemonic aids for picture recognition question the existence of important and general encoding deficits in HD. In the first of two experiments the influence of imagery on the acquisition and recall of 14-word lists was studied using a free-recall paradigm. Both HD patients and controls learned highly imageable words more quickly and retained them better than low imagery words over a 30-min delay. The impact of imagery on learning was apparent by the first trial. In the second experiment, a modified Brown-Peterson distractor paradigm was used to assess release from proactive interference (PI). It was found that both HD patients and controls exhibited comparable release from PI following a shift in taxonomic categories. The results of both experiments question the importance of encoding deficits in the memorial dysfunctions associated with HD.     

Utilization of base-rate information during feeling-of-knowing judgments.

We examined whether subjects use base-rate information about item difficulty when making feeling-of-knowing judgments for items they failed to recall. First, the subjects attempted to recall the answers to general-information questions. Then, for those items they recalled incorrectly, half of the subjects received information about the normative probability of recall of each item while judging their feeling of knowing. The other subjects made their feeling-of-knowing judgments without receiving any base-rate information. Finally, all subjects had a forced-choice recognition test on those items to validate the accuracy of their feeling-of-knowing judgments. Relative to the no-base-rate information group, the base-rate group had lower feelings of knowing for normatively difficult items and higher feelings of knowing for normatively easier items. Subjects who had received base-rate information during the judgment state had greater feeling-of-knowing accuracy than subjects who did not receive base-rate information. However, even the predictions from subjects who received base-rate information were not significantly more accurate for predicting subsequent recognition than were the predictions derived from normative information alone.     

Importance of the kind of cue for judgments of learning (JOL) and the delayed-JOL effect

The delayed-JOL effect is the finding in which judgments of learning (JOLs) are more accurate at predicting eventual recall when they are made a short time after study rather than immediately after study. The present research replicated this effect and found that the kind of cue that is used for JOLs is critical. In particular, following the study of stimulus-response paired associates, there is an extremely robust delayed-JOL effect when the cue for JOLs is the stimulus alone (every one of 45 subjects showed the effect); however, there is little, if any, delayed-JOL effect when the cue for JOLs is the stimulus-response pair. This finding has important implications for education: To have the greatest accuracy at predicting eventual recall, a person should make JOLs not immediately after study but, instead, shortly after study (i.e., delayed JOLs) with the cue for JOLs being the stimulus alone. The theoretical mechanisms for the delayed-JOL effect are currently unknown, but some speculations are offered.     

The retrieval of controlled and automatic aspects of meaning on direct and indirect tests

The literature concerning implicit memory presents conflicting evidence on the importance of meaning in recovering recently studied words. When the same cues are used during testing, indirect instructions reduce levels of processing effects relative to those obtained with direct instructions, suggesting that meaning is not as likely to be retrieved on indirect tests. However, with certain cues, meaning set size of the studied words affects performance even under indirect instructions, suggesting that meaning is retrieved on such tests. The purpose of the present experiments was to resolve this apparent inconsistency. In Experiment 1, the effects of levels of processing and meaning set size were evaluated under direct and indirect test instructions, with the use of stem and word-fragment cues. In other experiments, beginning and ending stem cues were compared, and levels, set size, and instructional effects were evaluated using meaning cues. The findings indicated that levels effects were determined more by test instructions than by test cues, and that set size effects were determined more by test cues than by test instructions. Implications are discussed for transfer-appropriate processing viewpoints and for a model in which it is assumed that performance is determined by searching either explicit or implicit memories.
