The four personality type combinations derived from high and low extraversion () and high and low neuroticism () have been related to response patterns composed of three symptoms (affective disturbances, thinking disturbances, and blackouts) scored as present (+) or absent (−) after a single oral dose of the hallucinogenic drug LSD-25. Hypotheses for expected response patterns for each personality group were derived from a data set obtained by Kohnen and Lienert (1987). Significance of associations was tested by two strategies of polyprediction configural frequency analysis (CFA): multiple uniprediction and biprediction CFA. Both strategies yielded a significant hyperpresentation of all three symptoms present in E+N+ (hysterics), merely thinking disorders in dysthymics (E−N+), merely affective symptoms in E+N− (stable extraverts), and merely blackouts in N−E− (stable introverts). Authors tried to relate these symptoms to Kretschmer's temperament types and could afterwards show by a chessboard modification of prediction CFA, that by applying two combined hypotheses for two personality types each, the significance of the predicted associations could be increased. 相似文献

Psychobiological responses to examination stress in repressors and sensitizers have rarely been investigated with respect to intraindividual response discrepancies. Furthermore, possible sex differences have rarely been taken into consideration. Therefore the present study investigated if repressors and sensitizers differ in their psychobiological responses to stress and if gender plays a modulating role. 30 and 29 students of both sexes selected from a total group of 96 students were classified as repressors or sensitizers each according to the repression-sensitization-coping-inventory (RSCI, Huwe et al.). State anxiety, heart rate, and cortisol in saliva served as indicators of stress. Sensitizers reported higher state anxiety and showed higher physiological stress responses than repressors. On the intraindividual level sensitizers reported high anxiety as compared to their low cortisol responses whereas repressors reported low anxiety as compared to their high cortisol increases. Gender had no modulating influence on stress responses in repressors and sensitizers. 相似文献

Only a very few studies on the effects of cold on human information processing appear to exist. Therefore, the present experiment
was designed to study the effects of the experimentally induced lowering of body core temperature on information processing,
while applying a reaction time paradigm. Thirty healthy male volunteers performed a stimulus evaluation—response selection
reaction time task after exposure to ambient temperatures of either 28 or 5°C. A 0.5°C-decrease in body core temperature resulted
in a significant increase in both reaction and movement time indicating a general deteriorating effect of lowering of body
core temperature on information processing. Mean reaction times were 538 ms and 549 ms for the control and the cold group,
respectively (p<.05). The respective mean movement times were 298 ms and 269 ms (p<.001). Speed of stimulus evaluation was not sensitive to decreases in body core temperature. However, response complexity
and body core temperature showed a significant interaction in their effect on movement time (p<.05), indicating that lowering
of body core temperature is more likely to affect response-related stages of central information processing rather than stimulus
evaluation. Furthermore, movement time appeared to be more sensitive to cold-induced effects on information processing as
compared to reaction time. Additional correlational analyses suggest that the observed effects can be considered as independent
of changes in skin temperature and experienced levels of thermal discomfort. Taken together, the results indicate that lowering
of body core temperature differentially affects various stages of information processing. 相似文献

A study was designed to answer the questions if low doses of ethanol would reduce stress induced increases in heart rates, if covariations would be observed between ethanol induced changes in heart rates and changes in emotional states and mental performance and if tolerance to ethanol or other personality factors would influence the ethanol induced cardiac effects. Forty-four male students with a history of high and low alcohol consumption according to questionnaire scores were matched for extraversion and neuroticism and then assigned to a group receiving either 0.8 g/kg of ethanol or a placebo drink. A stress condition of mental arithmetic was applied prior to and 45 minutes after ingestion of the drink. Heart rates and ratings of emotional states by adjective check lists were recorded before and after each stress session. A significant reduction of stress induced heart rate increases in both high and low drinking groups but no ethanol dependent change of resting heart rates were observed. Reductions of autonomic stress response by ethanol were weakly but positively correlated to respective reductions of affective stress responses and impairment of the quality of mental performance. High trait anxiety subjects seemed to benefit more from ethanol with respect to reductions of cardiac and emotional arousal than low anxious subjects. 相似文献

Our study examined variations in adolescent adjustment as a function of maternal and paternal parenting styles. Participants
included 272 students in grades 9 and 11 from a public high school in a metropolitan area of the Northeastern US. Participants
completed measures of maternal and paternal parenting styles and indices of psychological adjustment. Authoritative mothering
was found to relate to higher self-esteem and life-satisfaction and to lower depression. Paternal parenting styles was also
related to psychological adjustment, however, although the advantage of authoritative mothering over permissive mothering
was evident for all outcomes assessed, for paternal styles the advantage was less defined and only evident for depression.
Our study highlights the importance of examining process-oriented agents as part of the broader interest in well-being variations
in adolescents. 相似文献

The relationship between the incapacity to adapt behaviour to external requirements and biological irregularities of the menstrual cycle was investigated in 30 healthy females divided according to a questionnaire on behavioural adaptability into good (GAs) and bad (BAs) adaptors. Emotional states and blood samples for determination of hormones were obtained on ten defined days of the menstrual cycle, which were individually synchronized to six phases according to biological indicators. Comparison of GAs and BAs revealed that the incapacity of behavioural adaptation is associated with higher neuroticism related traits and states and that BAs exhibited higher cortisol and testosterone levels, lower luteal and follicular levels of estrogen, and lower luteal levels of progesterone. Furthermore, significantly more BA subjects suffered from corpus luteum deficiency. Results are discussed with respect to chronobiological biobehavioural mechanisms. © 1998 John Wiley & Sons, Ltd. 相似文献
