Data were obtained from 46 mother-child pairs from the Child Behavior Institute (CBI) at the University of Tennessee. These
mother-child dyads were referred for psychological help because of the child’s aversive behavior. Child-parent interactions
were quantified using a multi-code, observational system. Correlational and multiple regression analyses (stepwise) were conducted
to find the best predictor of the child’s aversive behavior. Results showed that the child’s aversive behavior was significantly
correlated with the mother’s aversive, indiscriminate, and compliance behaviors. The regression analysis showed mother’s aversive
behavior to be the best predictor of the child’s aversive behavior. Moreover, our results seem to point out that the compliance
hypothesis is more effective in predicting child aversive behavior than the predictability hypotheses. It appears that since
the two hypotheses are dealing with similar processes, they are more complementary than oppositional.
This study used data collected by the Child Behavior Institute (CBI) at the University of Tennessee, Knoxville. The authors
are indebted to Robert Wahler, Michael Smith, and Sue Dunn for their helpful comments on this paper. 相似文献

Older and young adults' letter detection and lexical decision performance were examined as word frequency varied to determine whether there were age differences in word recognition. Allen and Madden (1989) found that older adults' pattern of reaction time (RT) across word frequency categories was different from young adults' pattern for a letter detection task. In this study, for both letter detection and lexical decision tasks, older adults exhibited a monotonically decreasing RT function as word frequency increased. However, young adults exhibited a nonmonotonic RT function across word frequency for the letter detection task but a monotonically decreasing RT function as word frequency increased for the lexical decision task. An expanded parallel input serial analysis model of word processing was hypothesized. 相似文献

A within-subject comparison was made of the effects of methylphenidate (Ritalin) and response cost in reducing the off-task behavior of two boys, 7 and 8 years of age, who had been diagnosed as having an attentional deficit disorder with hyperactivity. Several dosages of Ritalin (5 to 20 mg/day) were evaluated with the results indicating varying effects of the drug for both children. Response cost (with free-time as the reinforcer) was superior to Ritalin in raising levels of on-task behavior and in improving academic performance. 相似文献

Subjects were tested on cross-and within-modality matching conditions with either a 5-sec or a 20-sec delay imposed between standard and comparison stimuli. Half the subjects were informed before the trial of what the comparison modality would be, while the others were not. There was a strong effect of instructions on the cross-modality conditions, but little on the within-modality conditions. The informed subjects showed better performance in the haptic-visual condition, while for the uninformed subjects, visual-haptic performance was better. The results suggest the importance of subjects’ processing strategies in cross-modality performance. 相似文献

College student subjects estimated the duration of time intervals (8–54 sec) by counting or not (N=35 per group). Counting eliminated the repetition effect (a decline in the magnitude of estimations across trials), and resulted in a truncation of the psychophysical function. The former result was interpreted as contrary to Treisman's (1963) model. The latter result was attributed to the effortfulness of counting, which was established in a subsequent experiment. 相似文献

To determine whether poor sleepers have a unique personality constellation significantly different from that of good sleepers, a sample of 162 emotionally disturbed adolescent poor sleepers was compared to a sample of 153 emotionally disturbed adolescent good sleepers on standardized personality instruments. Poor sleepers were found to have a high incidence of neurotic psychopathology with personality patterns characterized by depression, fearfulness, inhibition, anxiety, and rumination. In contrast, good sleepers showed quasi healthy and/or characterological patterns. While this study does not resolve cause and effect relationships, it does establish a highly significant relationship between neuroticism and sleep disturbance for adolescent boys and girls, and also demonstrates a similarity of personality dynamics and patterns between adult and adolescent samples of patients with sleep disturbances. 相似文献

This paper reviews a series of previous reports which summarize the physiology of chronic experimental epileptic foci in monkeys. It is shown that such monkeys can be trained to bidirectionally control the firing rates of normal and epileptic neurons which comprise the epileptic focus. As a result of this acquired operant performance, the monkeys show both a decrease in clinical seizures as well as a decrease in single unit epileptic activity. The EEC correlate of this change in single unit epileptic actvity is generalized EEG desynchronization. The conclusion from these data would indicate epileptic neurons can be operantly controlled and this control is not correlated with any specific EEG pattern. This brings to question the specificity of the SMR in EEG biofeedback paradigms which treat human epilepsy. This author feels that the result from such biofeedback studies are the result of the patient learning to manipulate electrical events within the CNS pathways through which the seizure propagates and is not contingent upon specific EEG frequencies. 相似文献
