We describe a custom-built feeder based on stepping motor technology controlled by a laboratory computer. The feeder dispenses
a wide range of foods: any fruit, vegetable, or nut. The feeder allows the investigator to reward monkeys with different foods
within a single experimental day. The monkey’s motivation to perform tasks is high and does not rely upon food regulation.
The avoidance of regulation, as well as the palatability and variety of the rewards dispensed by our device, distinguishes
it from commercially available products. We also describe the use of the feeder in the context of novel behavioral and neurophysiological
studies in freely moving monkeys. 相似文献

三种常用DIF检测方法的比较研究 总被引:6,自引:1,他引:5
本研究在对DIF作出新的更为严格的界定、对三种常用的DIF检澍方法进行详细介绍的基础上.以1999年高考英语试卷75道选择题为研究材料,对三种常用的DIF检测方法进行了实证研究。结果表明:MH方法与SIBTEST方法检测的敏感性较STND方法高;MH方法与SIBTEST方法检出的一致性很高;SIBTEST方法具有较好的性能,在实际应用中可以作为首选的方法;在进行DIF检测时,样本容量在1000左右为宜。 相似文献

跨文化协同增效研究的3种典型视角 总被引:2,自引:0,他引:2
随着经济全球化进程的加速,跨国公司日益重视运用多元文化来创造国际竞争优势。论文首先讨论了“跨文化协同增效”的内涵以及达成跨文化协同增效的标准,然后介绍了跨文化协同增效研究的3种典型视角:加拿大研究者Adler的研究视角、德国研究者Krewer的研究视角和印尼研究者Tjitra的研究视角。3种不同的视角体现出研究者自身文化的特点。前两种视角是从西方文化出发,认为必须创造“第三种文化”来达成跨文化协同增效,而后一种视角则是从东方文化出发,针对本国文化的独特性进行跨文化协同增效理论研究。最后在比较分析3种不同研究视角基础上,认为应借鉴国外学者的研究思路,针对独特的中国文化进行跨文化协同增效研究 相似文献

The objective of the present study was to investigate the relationship between ambivalent sexism and beliefs and attitudes towards menstruation, and, in turn, to study the influence of these variables on menstrual cycle‐related symptoms. One hundred and six Mexican women completed the Ambivalent Sexism Inventory, the Beliefs about and Attitudes toward Menstruation Questionnaire and the Menstrual Distress Questionnaire. The higher scores on benevolent sexism were associated with the most positive attitudes towards menstruation and also with the belief that a menstruating woman should or should not do some activities and that menstruation keeps women from their daily activities. The higher scores on hostile sexism were associated with rejection of menstruation as well as with feelings of embarrassment about it. Beliefs about and attitudes towards menstruation predicted menstrual cycle‐related symptoms related to negative affect, impaired concentration and behavioural changes, but did not predict somatic symptoms. These results will be useful to health professionals and advocates who want to change the negative expectations and stereotypes of premenstrual and menstrual women and reduce the sexism and negative attitudes towards women that are evident in Mexican culture. 相似文献

In this paper, we develop a latent processing ability model to analyze the speed of processing ability data. Our approach can not only effectively evaluate the effects of covariates on the latent processing ability, but also estimate the latent trait of each child by calculating its posterior mean. In addition, we derive the correlations structure of latent traits among different age groups. Simulations are conducted to evaluate the performance of our proposed model. The results indicated that the estimation of model parameters is satisfactory overall. The method is evaluated using real data from children aged 4–7 years in Changchun, China. 相似文献

We review sociological, correlational, and experimental research that examines the effect of a target's race on the decision to shoot. Much of this work involves computer‐based simulations of a police encounter, in which a participant must decide whether or not to shoot a potentially hostile target who is either Black or White. Experimental work with undergraduate participants reveals a clear pattern of bias (a tendency to shoot Black targets but not Whites), which is associated with stereotypes linking Blacks with the concept of danger. Subsequent work with police officers presents a more complex pattern. Although police are affected by target race in some respects, they generally do not show a biased pattern of shooting. We suggest that police performance depends on the exercise of cognitive control, which allows officers to overcome the influence of stereotypes, and we conclude with potential implications of this research for law enforcement. 相似文献
