This article is a commentary on Veit's article "Ratio and Subtractive Processes in Psychophysical Judgment." Veit's article makes an important contribution to the area of psychophysical judgment by providing a systematic approach that combines measurement and psychological theory. Using multi-factor designs and a cross-task scale-invariance criterion, Veit shows how to concurrently examine the integration rule, response-transformation function, and psychophysical function for judgment tasks. The need to expand this methodology to further understand the operations and processes underlying psychophysical judgment is stressed in the present article, and an illustration involving feedback mechanisms is provided. 相似文献

Previous research has shown that requiring children to trace from memory the correct member of a pictorial discrimination pair markedly facilitates performance. The experiment reported here offers support for a presumed component of this learning strategy, namely, “memory imagery.” In particular, subjects who traced directly on top of the correct picture did not perform as well as those who traced it from memory. Various theoretical explanations of the image-tracing phenomenon are considered, including depth of processing, dual coding, and frequency. 相似文献

Second- and sixth-grade children were presented a list of paired associates (concrete nouns) either at a faster (6-second) or a slower (12-second) presentation rate, under either an instruction to generate an interactive image for the pairs or a no strategy, control instruction. The list was composed of two pair types: easy-to-imaginally relate and difficult-to-imaginally relate pairs, as determined from a prior norming study. At the faster presentation rate, 2nd graders were able to benefit from the imagery strategy with easy pairs, but not with difficult pairs. At the slower rate, however, they applied the imagery strategy equally well to both pair types. Older children benefited from the imagery strategy with both pair types at both rates. 相似文献

Recovery from acute aphasia after closed head injury was studied in 21 young adults at least 6 months after injury. Three profiles of scores were found using standardized language tests. Persistent expressive and receptive impairment was present in 6 patients who sustained severe diffuse brain injury resulting in global cognitive deficit. Residual expressive impairment, primarily of naming, was associated with mild diffuse brain injury though focal left-hemisphere injury was present in 3 of 6 cases. Patients who recovered to normal levels on all language tests generally had acute neurologic findings consistent with mild diffuse brain injury. Cranial computed tomography at the time of followup frequently disclosed ventricular enlargement. 相似文献

In Orthodox Jewish communities, mothers are expected to breast-feed their infants and this expectation is to some extent based on religious beliefs. The degree to which this expectation promotes breast-feeding success was assessed by comparing a group of 50 Orthodox Jewish mothers with a group of 50 secular Jewish mothers in regard to infant feeding practices. All of the women lived in the Yeoville suburb of Jahannesburg, South Africa. An effort was made to interview all Orthodox mothers with at least 1 child under the age of 5 living in the area and it was assumed that the 50 mothers in the study constituted all or most of that population. A group of 50 secular mothers, comparable in age, education, and general living conditions, was also interviewed. The 50 Orthodox mothers had a total of 155 children and the secular mothers had a total of 119 children. Despite the quasi-religious motivation of the Orthodox mothers to breast-feed, there were few differences in the infant feeding practices of the 2 groups. At the age of 1 month the ratio of breast-fed to bottle-fed infants was 2.5:1 for the infants of Orthodox mothers and 2.3:1 for the infants of secular mothers. At age 6 months the ratio was 1:3 for both groups. At age 9 months the ratio was 1:6.4 for Orthodox mothers and 1:6 for secular mothers. The children of Orthodox mothers were breast-fed for an average of 5 months while the children of mothers of secular children were breast-fed for 4-1/2 months. 相似文献

This study examined cardioprotective avoidance beliefs and general panic/agoraphobia variables among 45 Emergency Department patients with a primary complaint of noncardiac chest pain (NCCP) in the absence of coronary artery disease or other medical explanation. Cardioprotective beliefs about the dangerousness of work and physical activity were assessed with the Fear-Avoidance Beliefs Questionnaire (FABQ). Additional measures assessed complaints of cardiac distress and panic, anxiety sensitivity, panic-related beliefs, agoraphobic avoidance, and depressive symptoms. Hierarchical regression analysis indicated that cardiac distress symptoms are a function of panic symptoms and cardioprotective beliefs concerning both physical activity and work, with 62% of the total variance explained. The predictors also explained 57% of the variance in Emergency Department utilization, which was significantly related to cardiac distress symptoms, number of illnesses, and work-avoidance beliefs. Neither outcome was related to demographics, depression symptoms, general anxiety sensitivity, general panic cognitions, or agoraphobic avoidance. Results suggest that current behavioral understandings of NCCP might be advanced by further examination of cardiac-specific avoidance beliefs and behavior and the potential role these factors play in both symptom experience and medical utilization. 相似文献
