Religious orientation and coping with cancer

In this study we investigated the role of religious orientation in coping with stresses associated with cancer. A measure of daily coping and the Religious Orientation scale were administered to forty hematology-oncology patients in order to examine frequency of eight coping responses across religious orientations. It was found that proreligious and intrinsic participants used religion significantly more often than nonreligious and extrinsic types to cope with stresses associated with their cancer. We concluded that religious orientation and commitment influence the coping process, and suggest that religious commitment be included in studies of coping with cancer.     

SLEEP DEPRIVATION,ALLERGY SYMPTOMS,AND NEGATIVELY REINFORCED PROBLEM BEHAVIOR

We studied the relation between the presence versus the absence of sleep deprivation or allergy symptoms and the rate and function of problem behavior. Three students whose problem behavior was negatively reinforced by escape from instruction were studied across several weeks using analogue functional analyses. Our results indicated that the extraexperimental events were associated with (a) termination of instruction functioning as a negative reinforcer, (b) increased rates of negatively reinforced problem behavior, or (c) increased rates of problem behavior across all conditions.     

Affective, Continuance, and Normative Commitment to the Organization: An Examination of Construct Validity

Within the past few years, several studies have used the Affective, Continuance, and Normative Commitment Scales (Allen & Meyer, 1990; Meyer & Allen, 1984, 1991) to assess organizational commitment. The purpose of this paper is to review and evaluate the body of evidence relevant to the construct validity of these measures. Although some empirical questions remain at issue, the overall results strongly support the continued use of the scales in substantive research.     

Criterion validation of two approaches to performance appraisal: The behavioral observation scale and the relative percentile method

We compared the criterion validity of a new relative performance appraisal format (percentile-based ranking) to that of an absolute format (BOS) in a sample of 88 unit managers. Overall, our results suggest that the relative format has higher criterion-related validity than does the absolute format. These findings contradict conventional wisdom that format-related differences in measures of performance are minimal and that relative approaches to performance appraisal are inferior.This research was supported by grants from the Social Sciences and Humanities Research Council of Canada (SSHRC) to Richard D. Goffin, Douglas N. Jackson, John P. Meyer, Sampo V. Paunonen, and Mitchell G. Rothstein. Additional funding provided by a research grant from Imperial Oil Ltd. to Douglas N. Jackson.A version of these results was presented at the 7th Annual Meeting of the Society for Industrial and Organizational Psychology, Montreal, Canada, May, 1992. Limited portions of these data, addressing distinctly different research issues, were published in Gellatly, Paunonen, Meyer, Jackson, & Goffin (1991) and Meyer, Paunonen, Gellatly, Goffin, & Jackson (1989).     

Co-morbidity of crying and feeding problems with sleeping problems in infancy: Concurrent and predictive associations

The co-morbidity of crying, feeding and sleeping problems at 5 months of age was investigated in a representative sample of 432 infants in South Germany. A crying, sleeping or feeding problem was reported in 32.7% of these infants by their parents and a further 14.6% had two or more of these problems. Little co-morbidity between crying and feeding problems was found. There were moderate to strong associations between crying and sleeping behaviours. Feeding problems showed little relationship to sleeping behaviour, but feeding type and frequency of feeds were related to night waking. Breastfed infants woke much more often at night. Crying and feeding problems at 5 months were poor predictors of sleeping behaviour at 20 or 56 months of age. Later sleeping behaviour was best predicted by infant sleeping behaviour. At 56 months, maternal distress due to sleeping and co-sleeping practices was predicted by maternal distress due to crying and feeding practices at 5 months of age. The predictions were significant but generally weak to modest in strength. Future studies on the consequences of crying or feeding problems should take into account patterns of co-morbidity. So-called ‘post-colicky’ sleep problems are not due to increased crying per se but rather appear to be the consequence of associated infant sleeping problems and parental caretaking patterns for dealing with night waking in infancy.     

Eye-hand coordination: oculomotor control in rapid aimed limb movements

Three experiments are reported in which Ss produced rapid wrist rotations to a target while the position of their eyes was being monitored. In Experiment 1, Ss spontaneously executed a saccadic eye movement to the target around the same time as the wrist began to move. Experiment 2 revealed that wrist-rotation accuracy suffered if Ss were not allowed to move their eyes to the target, even when visual feedback about the moving wrist was unavailable. In Experiment 3, wrist rotations were equally accurate when Ss produced either a saccadic or a smooth-pursuit eye movement to the target. However, differences were observed in the initial-impulse and error-correction phases of the wrist rotations, depending on the type of eye movement involved. The results suggest that aimed limb movements use information from the oculomotor system about both the static position of the eyes and the dynamic characteristics of eye movements. Furthermore, the information that governs the initial impulse is different from that which guides final error corrections.     

Cholinergic modulation of tonic immobility in the rabbit (Oryctolagus cuniculus).

The present study was performed to determine the effects of the anticholinergic agent scopolamine and the cholinergic agent physostigmine on tonic immobility in rabbits. Recordings of the electroencephalographic (EEG) activity from cortex and hippocampus were also made before, during, and after each test session. Scopolamine significantly prolonged the response and produced large amplitude slow wave activity in the EEG of both cortex and hippocampus. Physostigmine significantly shortened the duration of immobility and increased rhythmic slow activity in the frequency range of 5.5-9.1 Hz in the hippocampus while producing a desynchronized cortical rhythm. It is suggested that the cortex and hippocampus play a role in modulating tonic immobility duration by inhibiting the brain-stem structures thought to control this response.     

Suppression of precocial copulation by progesterone implants in the male chick forebrain.

Precocial copulation in 2-wk.-old male chicks, described behaviorally as free mount, tread, posterior contact, waggle, peek, and seize, was developed through hand-training experience and androgen treatment. Crystalline progesterone was then implanted in various forebrain or midbrain regions. Results indicated that progesterone inhibited copulatory behavior when placed in the periventricular areas of the preoptic-hypothalamic continuum. Progesterone implants in the preoptic lateral forebrain bundle regions also suppressed precocial copulation. Forebrain implants of cholesterol did not result in copulatory inhibition. The suppression of copulatory behavior was not accompanied by loss of weight or deficits in general activity or comb growth. These data indicate that brain regions responsible for progesterone-induced copulatory inhibition are similar in neuroanatomical distribution to those involved in testosterone-induced copulatory activation.     

Visual masking,mental age,and retardation

Performance of retarded subjects under both forward and backward masking was less accurate than either an equivalent chronological age or equivalent mental age group of normals. It was suggested that the iconic memory impairment of retarded subjects in attributable in part to mental retardation and not simply to low mental age.
