初级指挥官人格类型与PM领导行为类型有效性的关系 总被引:4,自引:0,他引:4
通过对陆军初级指挥官人格心理类型与领导行为有效性的心理学研究 ,探讨个人的领导潜能、人格心理类型对领导行为有效性的影响。研究发现 :1方差分析表明 ,具有不同领导行为的指挥官在人格维度上存在明显的统计学差异。提示了指挥官的领导行为取向与人格因素有密切的关系。2卡方分析结果也表明 ,PM型行为的军官在其人格特征上具有“ESTJ”组合特征 ,而 pm型的军官则正好相反 ;另外 ,pm型的军官在成就动机上获得高分的人数最少。3系统聚类分析显示 ,“成就动机”、“感觉”和“判断”三种人格因素与军事指挥官完成整体领导职能有着更为密切的关系。 相似文献

追踪作业中几种心理负荷评估指标敏感性的研究 总被引:1,自引:0,他引:1
本研究在模拟追踪作业情境下 ,对主任务绩效测定、主观评定和若干生理测量在心理负荷评估中的敏感性进行了实验。实验采用重复测量的被试者内设计 ,2 0名被试 (男女各半 )在六档负荷下分别从事五分钟追踪作业。所选用的指标有追踪作业平均误差距离、追踪警告次数、主观负荷评定、心率、心率变异和血压。结果发现 :1主任务绩效在评估追踪作业心理负荷中具有最高的敏感性 ,主观评定次之 ,心率变化率和心率变异变化率也随负荷变化 ,血压指标随负荷变化的趋势不明显 ;2除血压指标外 ,其余各指标之间均存在明显的相关 ,这提示它们在评估追踪作业心理负荷中具有较大的可靠性。 相似文献

The relationship of locus of control to depression, anxiety, hostility, and physical health was assessed in a sample of multicultural
college students (N = 162). Powerful Others Health Locus of Control was correlated with depression, anxiety, hostility, and
recent physical symptoms while Chance Health Locus of Control (CHLC) was correlated with all of the above as well as chronic
physical symptoms and major health problems. When controlling for a variety of health risk factors (viz., age, sex, body mass,
exercise, smoking, salt, alcohol, and caffeine), only CHLC remained significant in the physical health models. Results support
the cognitive model of mental health which emphasize the importance of adaptive beliefs. Specifically, they suggest that issues
about control are related to negative affect and indicate that the often-cited relationship of an external locus of control
to depression and anxiety also holds for hostility. The findings do not, however, support the view that anxiety and depression
are associated with different types of external locus of control but rather suggest a unified set of locus of control beliefs
underlying the three types of negative affect. In addition, evidence is provided for the external validity of the Multidimensional
Health Locus of Control (MHLC) Scales with respect to mental health. Further, the results indicate that belief about one’s
health may play a significant role in one’s physical health and that the health behavior model of the relationship between
locus of control and physical health is insufficient to explain the relationship. As the Chance and Powerful Others MHLC scales
were not related to health habits in this sample but were related to mental health (viz., depression, anxiety, and hostility),
locus of control beliefs may be related to physical health via their relationship with mental health. 相似文献

present research examined the role of hippocampal NMDA-dependent synaptic potentiation on appetitive instrumental conditioning
under a continuous reinforcement schedule. In the first experiment, low (.025 mg.kg) or moderate (.05 mg/kg) dosages of the
NMDA receptor antagonist, MK801, failed to increase the number of training days required to reach acquisition criterion; number
of training days required to reach criterion for extinction were also unaffected. In the second experiment, a higher dosage
(.10 mg/kg) of MK801 or induction of long-term potentiation failed to alter the number of responses occurring during acquisition.
These data suggest that hippocampal synaptic potentiation does not play a prominent role in instrumental learning with simple
contingency conditions. It is suggested that hippocampal LTP reflects a perceptual process that contributes differentially
to spatial cognition, classical and instrumental conditioning. 相似文献

This study examined the extent to which psychologists, when compared to university professors and evening school students,
employ individualist values differentially in their responses to vignettes describing males and females. The participants
responded to 6 vignettes by choosing initial hypotheses that reflected either utilitarian (tradition-ally masculine) or expressive
(traditionally feminine) themes. Two vignettes involved a sex of client manipulation, but neither resulted in a sex of client
effect. An analysis of the responses to the remaining 4 vignettes indicated a marked preference for the masculine form of
individualism for males, but were evenly divided for females in all three groups. These results suggest that psychologists
were just as likely to engage in bias as others. 相似文献

High-probability requests were used to increase social interactions in 3 young boys with severe disabilities who had been identified as severely socially withdrawn. A multiple baseline design across participants was used to evaluate the effects of high-probability request intervention on (a) social initiations, (b) social responses, (c) continued interactions, and (d) performance of high- and low-probability requests. The students were observed in a second setting to examine generalization effects across peers who did not participate in the training sequence and settings. The results demonstrated that the high-probability requests increased the students' responsiveness to low-probability requests to initiate social behavior. Increases were also found in (a) unprompted initiations and extended interactions to the training peers, (b) unprompted initiations and extended interactions to peers who were not involved in the training procedure, and (c) generalized unprompted initiations and interactions in a second nontraining setting. The students maintained increased levels of initiations and interactions after all prompts were removed from both the training and nontraining settings. 相似文献

A preference-based measure of responses to warning labels was used to study alternative alcohol warning labels that differed in: (a) length, (b) presence of qualifier words, (c) alternative content, and (d) specific beverage. The specific risks mentioned were more important than the overall label length, qualifier words reduced avoidance responses, various alternative warnings elicited more avoidance responses than the existing alcohol warning label, and more avoidance responses were made to labels on a whiskey bottle than on a beer bottle. Warnings with the words “poison,”“cancer,” or “health problems” were the most powerful. The results for college students in Study 1 were replicated in a high-school sample in Study 2. 相似文献
