The present study aimed at comparing participants with and without self reported musculoskeletal pain in a normal population with regard to performance on a range of tests for episodic memory, semantic memory, and other cognitive functions and to see if expected differences interacted with age. The results showed that participants with pain performed worse on a range of tasks as compared to participants without pain, and that these differences occurred regardless of age. The most robust effects of pain were displayed on tests for vocabulary and construction ability as these were the only effects that remained significant after controlling for years of education and reported depression in separate analyses. When depression and education were controlled for in the same analysis, even these effects were eliminated, suggesting interplay between pain, depressive status, and educational level in the negative effects on cognitive functioning. 相似文献

There is accumulating evidence to suggest that social phobia is associated with attentional bias for words related to social threat. Information processing in individuals with social phobia (n = 87) was investigated in the present study using 2 versions of the emotional Stroop task. Results from a standard emotional Stroop task indicated delayed colour naming of socially threatening words relative to neutral words, in line with previous research, whereas results from a Web-based emotional Stroop task indicated a facilitation effect, with faster manual indication of colour choice for socially threatening words than for neutral words. Possible explanations for these contrasting findings and issues for further research are discussed. 相似文献

Twelve female and twelve male Wistar rats were assigned to home groups, platform-control groups, and rapid eye movement sleep deprivation groups. The deprivation was performed with the cuff-pedestal method. Rats were tested in pairs in a shrinking chamber to increase proximity of the rats and to provoke interaction between them. An increase in boxing behavior was noted in the sleep-deprived groups. The result confirms that deprivation of rapid eye movement sleep increases aggressive behavior in the rat. However, this behavior is not influenced by the area of the testing arena. The sleep-deprived females explored each other more than the controls; the males' behavior did not differ in this respect. The amount of genital exploration decreased with diminishing area of enclosure, whereas boxing was not area dependent. 相似文献

In Swedish welfare agencies, it was found that the importance of characteristics of social research for utilization was related
to three intervening factors: the context of origin of the research, the functions for the user and the utilization context.
These factors seem to explain the difference between competing notions on the importance of scientific sophistication for
research utilization.

Summary The well-known visual effect of seeing an isolated, point on the rim of a rolling wheel as moving in a cycloidal track was used for a study of visual vector analysis under non-redundant conditions.Under actual experimental conditions a mean difference of about 20% was found between the mathematically predicted and the perceptual vector analysis. A considerable interperson variation in deviation from the analysis was found. Some Ss showed a deviation of only a few per cent from the mathematically correct response.This investigation was made possible by grants from the Swedish Council for Social Science Research. 相似文献

Two sentences were constructed having roughly the same content but different predictability ( P -) scores. One or other of the sentences was presented auditorily once only to different groups of subjects who were instructed to listen carefully, without however, being informed of the learning character of the experiment. The groups were then tested for retention after one of the following intervals: IM, 3 min., 2 hours, 20 hours. The sentences were found to differ in memorability (amount recalled) in IM but not in LTM. The reproductions were also analysed with regard to synonym and non-synonym substitutions and the implications for the chunking hypothesis discussed. 相似文献

A small, light eye-movement recorder, capable of registering eye movements from the smallest voluntary movements to movements of 20 degrees of arc, is described. A miniature light projector gives a beam of infrared (or blue) light, which is reflected by the cornea of the eye. The beam is deflected by any movement of the eye. An optical system transforms the motion of the beam into changes of light intensity. These are translated into magnified fluctuations of current in a multiplier phototube. The output is translated into graphic form by an ink-writer fitted with a D.C. amplifier. The apparatus, except for the writer but including a helmet, weighs about 300–500 g and is mounted on the subject's head without appreciably disturbing the field of vision. 相似文献

This is a study of perception of bending motion and jointed rigid motions over large invisible segments of a bending line. In this project, we investigated the visual perception of changing form of lines, built up by a series of dots and presented under highly reduced pictorial conditions. The changing form was indicated by one or two moving and continuously changing visible fragments of the line. The most extreme condition studied was the perception of the bending of an initially vertical 24-dot line, visually represented only by the stationary base dot and the two moving dots at its top. In this experiment, nearly all subjects reported experiencing a smooth bending connection over the 21-dot empty gap. Three experiments are described and analyzed. The results suggest that the human visual system is astonishingly well adapted for derivation of relevant figurai information from such severely reduced, continuously changing optical presentation. An explanation in terms of automatic sensory mechanisms related to the physiological receptive field effect is proposed. 相似文献

L ambert , W. W., J ohansson , G., F rankenhaeuser , M. & K lackenberg -L arsson , I. Catecholamine excretion in young children and their parents as related to behavior. Scand. J. Psychol ., 1969, 10, 306–318. — Catecholamine excretion in 100 children and their parents was examined in relation to the children's behavior and to data on the parents' disciplinary procedures: ( a ) children's adrenaline excretion was positively correlated with their intellectual level, ( b ) their noradrenaline excretion was positively correlated with that of their mothers, as well as with both parents' age at the birth of the child, ( c ) mothers' adrenaline excretion was positively correlated with the frequency at which the fathers punished their children by smacking, and ( d ) fathers' noradrenaline excretion was negatively correlated with their own as well as with their wives' frequency of smacking their children. 相似文献
