Balancing Elder Care Responsibilities and Work: The Impact on Emotional Health

The current study investigated the effects of balancing elder care and work on emotional health. Responses from 43 retired caregivers, 211 not retired caregivers, 49 retired non-caregivers, and 224 not retired non-caregivers, who had participated in the national Health and Retirement Study, served as the data base. Results indicate that Caregiver Status (Caregiver vs. Non-caregiver) and Retirement Status (Retired vs. Not Retired) interact, depending on the measure of emotional health. The relationship between the number of depression symptoms reported and Caregiver Status depended on whether the respondent was also retired or employed; a significant interaction was not found when emotional health was measured with one overall item. A significant difference was not found between employed caregivers and employed non-caregivers, in terms of emotional health. Employed caregivers who gave more caregiving hours did report poorer emotional health than employed caregivers who gave fewer hours. Female caregivers reported more depression symptoms than male caregivers. The results suggest that employers may need to develop interventions which may help caregivers who are highly involved with caregiving responsibilities.     

Effectiveness of a Cognitive Behavioral Intervention for Young Adults with Cystic Fibrosis

This study examined the effectiveness of a cognitive behavioral intervention for young adults with cystic fibrosis (CF). Four young adults were referred for the therapy by medical staff because of perceived problems with anxiety, anger, or coping. Treatment impact was assessed on measures of anxiety, anger, perceptions of functional disability, and coping. A multiple baseline design across subjects was used. Overall, the impact of the cognitive behavioral intervention for young adults with CF was mixed. If participants had elevated baseline scores on anxiety, anger, or perceived functional disability, then some improvement was shown. However, only one participant had elevated baseline anxiety and anger scores, while two had higher functional disability scores. For coping, only one participant clearly displayed a greater use of approach relative to avoidance coping by the end of treatment. Results are discussed in terms of treatment implications, assessment, and coping issues.     

Regulation of division of labour between cognitive systems controlling action

The brain has evolved a division of labour amongst component systems which link different sorts of processing with precise actions. Debate is over centralized versus decentralized control at different processing levels, from cognitive systems to motor-control systems. With simultaneous activation of alternative expert systems which link (a) picture-processing with drawing and (b) reading with writing, decentralized modelling predicted both the averaging of action-production times and additive effects of neural noise. Such modelling has the advantage of being able to measure the cost of regulation both within and between systems, in a common metric of performance variability. That commonality strengthens the trend to regard the brain as a distributed super-system with a great deal of regulation done towards the output end.     

The Temporal Unfolding of Local Acoustic Information and Sentence Context

The purpose of this study was to investigate the temporal unfolding of local acoustic information and sentence context using both cross-modal interference (CMI) and word-monitoring tasks. The timing of sentence context effects have important theoretical implications for models of language processing (e.g., initial context independence vs. initial interaction). Yet, different tasks tend to yield different results. For both experiments, stimuli from an acoustically manipulated goat-to-coat continuum were embedded in sentences whose interpretation was biased toward either goat or coat. In experiment 1 (CMI), the primary task was listening to sentences for comprehension; the interference task was a word/nonword decision to an unrelated visual probe that appeared at one of three positions within the sentence. Results showed immediate effects of the acoustic manipulation, but only delayed effects of sentence context. These results were interpreted to indicate that phonological processing is initially context-independent but is followed by rapid context integration. Experiment 2 used a word-monitoring task: Response times were significantly longer when sentence context was incongruent with the monitoring target, showing an immediate effect of context. The apparently contradictory results of the two experiments together support an account of language processing in which phoneme categorization is initially independent of sentence context unless an explicit judgment about the identity of the target is required.     

Inhibition of passive-avoidance memory formation in the day-old chick by the opioid cytochrophin-4

Cytochrophin-4 (cyt-4), a tetrapeptide with opioid-like activity, caused amnesia when injected into chick forebrain 5 hr after passive-avoidance training. Bilateral injections of cyt-4 directly into the lobus parolfactorius (LPO) resulted in the chicks being amnesic for the training task 24 hr later, whereas unilateral injections of cyt-4 were effective only when injected into the right LPO. Cyt-4-induced amnesia was reversed by the general opioid antagonist, naloxone, indicating that cyt-4 was acting via an opioid receptor. The mu- and delta-opioid receptors (but not kappa-opioid or ORL(1)-receptors) have been shown to be involved in memory formation 5 hr after training (). Because an antagonist of the mu-opioid receptor inhibited memory, we attempted to reverse the effect of cyt-4 using mu-opioid receptor agonists. Met[enk] was unable to reverse the inhibition of memory formation by cyt-4 suggesting that the mu-opioid receptor is not involved in this effect. However endomorphin-2 (endo-2) reversed the effect of cyt-4. We further investigated the action of endo-2 using an irreversible antagonist of the mu-receptor, beta-funaltrexamine (beta-FAN), and found that endo-2 reversed beta-FAN-induced amnesia indicating that endo-2 was not acting on the mu-opioid receptor in the chick. Because unilateral injections of beta-FAN were not amnesic (bilateral injections were amnesic) this provided further evidence that the effect of cyt-4 was not mediated via the mu-opioid receptor. Coinjection of the delta-receptor agonist, (D-Pen(2), L-Pen(5))enkephalin (DPLPE), reversed the disruptive effect of cyt-4 on memory. However, memory modulation via the delta-opioid receptor was not lateralized to the right hemisphere suggesting that cyt-4 does not act via this receptor either. It was shown that an antagonist of the epsilon-opioid receptor inhibited memory at the 5 hr time point. We conclude that the epsilon-opioid receptor or an unidentified opioid receptor subtype could be involved in the action of cyt-4.     

Characteristic patterns of word association responses in institutionalized elderly with and without senile dementia

This study examined the responses of 91 institutionalized elderly persons to the Goldfarb-Halpern Word Association Test (1981), Journal of Speech and Hearing Research, 24, 233–246. Subjects with senile dementia evidenced a characteristic pattern of responses which included marked reduction of paradigmatic responses, no decrease in syntagmatic responses, and a marked increase in unclassifiable and multiword responses not previously reported in the literature. The declines and increases appeared linear and progressive with severity of dementia. The pattern was distinct from that of any other adult group previously tested with this tool. Institutionalized elderly subjects without senile dementia performed similarly to previously tested noninstitutionalized elderly. Theoretical and clinical implications are discussed.     

Use of a raster framebuffer in vision research

For the study of human and animal vision, the video framebuffer is the only technology that is capable of displaying two-dimensional images with precise control of contrast, luminance, and display timing. The video framebuffer also allows precise control of color. However, this device is not designed for precise psychophysical displays, and techniques must be developed to use them in this role. In this paper, we describe a number of basic methods used in our lab. In order to be concrete, we use an Adage RDS-3000 raster display system (Adage, 1982) as an example, since that is the device we have actually used. The Adage is hosted by a PDP-11/73 under the Venix operating system. The principles generalize to other machines. Where it clarifies the issues, we have shown the syntax of the software routines involved.     

Women's communication in Mexican organizations

This study attempts to derive a communication profile of women in Mexican organizations of the private sector. The questions that guided the study were the following: (1) Do women perceive their communication behaviors as similar to or different from those of men at their same organizational level? (2) If women do perceive differences, what is their nature? (3) Do perceived similarities to and differences from men vary by organizational level? Forty-five women in 14 Mexican organizations were intensively interviewed in the winter of 1980. The interviews were distributed equally at three organizational levels—secretarial, middle management, and upper management. It was found that women respondents perceive themselves to differ from men on 18 of 40 verbal and nonverbal communication variables. The average woman in this study perceived that verbally she is more courteous, cheerful, assertive, careful, likely to talk with males, self-confident, and directive than men, and that she expresses less agreement than men. Nonverbally, the average woman was found to look more at the eyes, smile more, give more attention to dress, be more punctual and flexible than men, and to be less rigid in posutre, touch less, invite co-workers to her home less, and take less work home. Organizational level differences were also found. The results are discussed in the light of the theoretical paradigms presented in the study.
