A study of object naming in 202 children, aged 5–11 years, demonstrated that varying the stimulus context affected the level of response accuracy. From age 6 to 10, completing a sentence with a noun (auditory) yielded the lowest error scores, naming objects upon hearing a definition (also auditory) produced most errors, while responding with names to pictured objects was of intermediate difficulty. This is the same order of object naming difficulty found in adult aphasic patients. Children older than 10 do not appear to be affected by stimulus context in their object naming. Results are discussed in terms of the relative syntactic difficulty of the two auditory conditions, the unexpected sex differences, and the “aphaseoid” naming errors of children. 相似文献

The Psychometric Bisection Function for time relates the discriminability of intermediate duration stimuli to a short and long training duration. Bisection Functions for animals (R. M. Church & M. Z. Deluty, Journal of Experimental Psychology: Animal Behavior Processes, 1977, 3, 216–228) confirm Weber's Law and also show indifference between short and long reports at the geometric mean of the training durations. Two discrimination processes are studied which, in combination with different constructions of the subjective time scale, result in Bisection Functions which differ in form and location. The two discrimination processes use a likelihood ratio rule or a similarity rule to compare intermediate durations to the training durations. These rules in combination with two different constructions of the subjective time scale result in four models which conform to Weber's Law. For one of the scales subjective time is a power function of real time with the scalar property on variance (Scalar Timing). For the other, subjective time is a logarithmic function of real time with constant variance (Log Timing). Both Log and Scalar Timing assume normality on the subjective scale. Only three of these models also entail the geometric mean at the indifference point. The exception is Scalar Timing with the likelihood ratio discrimination rule. This model entails indifference at approximately the harmonic mean of the training stimuli. Variants of the remaining three models differ theoretically but alternatives are difficult to discriminate empirically. A contrast is provided by a Poisson Timing subjective scale in which variance increases directly with the mean. This scale results in indifference at the geometric mean for both discrimination rules but violates Weber's Law in both cases. 相似文献

The Social Readjustment Rating Scale (SRRS) was administered to 185 subjects whose age ranged from 21 to 61 yr. The responses were factor analyzed for a principal axis solution followed by isopromax oblique rotation. All the items were loaded and clustered under five factors labeled as follows: (1) personal growth, maturation, and renewal; (2) tension and uncertainty; transitions in personal or occupational situations; (3) changes in one's usual routine and relationship; (4) significant changes in family or mirriage; and (5) personal catastrophies. Males scored significantly higher than females on factors 4 and 5. There were no age differences in the obtained scores. The finding of the factorial structure was thought to add credence to the scale especially in view of past criticism. Implications for future research were also discussed. 相似文献

This paper generalizes Stone's (1960, Psychometrika 25, 251–260) random walk model of two choice response times (RTs) that is based on the sequential probability ratio test (SPRT) and that predicts equal correct and incorrect RTs to the same response. The generalized version allows a bias of the type found in signal detection theory to enter directly into the accumulation process so that ambivalent evidence may be seen as slightly favoring one alternative. The resulting biased SPRT model can predict any relation between correct and incorrect mean RTs. In particular, unlike the special symmetric case of Link and Heath's (1975, Psychometrika 40, 77–105) relative judgment theory (RJT), the biased SPRT model can predict that correct mean RTs are faster for one response but slower for the other. The biased SPRT model, the classical SPRT model, and the symmetric RJT model are all fit to the data of an RT deadline experiment reported by Green and Luce (1973, Attention and performance, New York: Academic Press) and it is shown that, of the three, the biased SPRT model provides the best account. Finally, a method for incorporating the same sort of bias into RJT models is sketched out. 相似文献

In Experiment 1 nonmusicians were presented with dichotic melodies, which differed either on all pitches or by a single note, followed by a set of four binaural melodies. They were asked to recognize among the alternatives only one member of the dichotic pair in the “single-focus” task, and both dichotic melodies in the “double-focus” task. These different attention requirements led to a LEA in the first task which contrasted with the REA observed in the other task when melodies differed by all pitches. A possible confounding (fusion of the common pitches) prevents comparison of the tasks for melodies differing by a single pitch. The role of the extent of melody differences was further investigated in a second experiment by changing melodies on one, two, or three notes. No effect of material was observed on ear asymmetries. Task demands appeared as the most critical determinant of ear differences and are discussed in terms of their particular influence on the adoption of an analytic or holistic processing mode. Male subjects were found to be more responsive than females to analytic processing suggestions. 相似文献

The elements of the Habit Reversal Treatment Package developed by Azrin and Nunn (1973) to counteract nervous habits were systematically analysed. Fifty nail biters (92% reported biting their nails for more than 5 yr) were randomly assigned to one of the following treatments: Habit Reversal, Habit Reversal and Self-Monitoring, Self-Monitoring, Self-Monitoring and Daily Graph Plotting, Waiting List control, Pictures of both hands were taken prior to the commencement of treatment and at 6 and 12 weeks after treatment termination. The results showed that the four treatment groups improved equally compared with the control subjects. Such data cast doubt on the importance of learning an incompatible response in Habit Reversal Treatment. An alternative explanation based on increasing the subject's awareness is put forward. 相似文献

Fazio, Zanna, and Cooper (Dissonance and self-perception: An integrative view on each theory's proper domain of application. Journal of Experimental Social Psychology, 1977, 13, 464–479) specified mutually exclusive domains of application for dissonance and self-perception theory and used a misattribution-of-arousal procedure to distinguish between dissonance reduction and self-perception processes. Because their proposed limitations of the domains of the two theories and their use of the misattribution procedure are not directly derivable from earlier statements of either theory, it may be best to regard their analysis as a new theory, rather than as a conciliation of the parent theories. New analyses based on the Fazio et al. results indicate that their data provide an insufficient basis for preferring their theory to earlier versions of dissonance and self-perception theories.

A series of studies investigating the psychometric and conceptual properties of the Survey of Ethical Attitudes (SEA), a paper-and-pencil measure of moral reasoning, is reported. The results of these studies indicate that the scale is clearly susceptible to the influence of response dissimulation in the form of both role-playing and impression management, and is also confounded with sources of stylistic variance in the form of social desirability. Previous proposals concerning the relationships among moral development, moral reasoning, and personality structure are reviewed in light of these findings, and an alternative conceptualization of the measure in terms of political and social attitudes is offered. 相似文献
