The purpose of the present study was to determine if aphasic subject groups differentiated by the fluency of their verbal output employed rehearsal as a strategy for maintaining verbally coded information in primary memory. A task based upon the Brown-Peterson paradigm was administered to 10 fluent aphasic patients, 10 nonfluent aphasic patients, 10 right-brain-damaged patients, and 10 nonneurological patients. The findings indicate that the nonfluent aphasic patients did not rehearse the verbal information while the fluent aphasic, right-brain-damaged, and nonneurological patients did rehearse. In addition, both fluent and nonfluent aphasic patients encoded significantly less information into the memory system initially and performed worse on the task overall than right-brain-damaged and nonneurological patients. 相似文献

Interaction behaviors and language measures of low income mothers and their 12-month-old infants were compared for floor-play situations in which the mother was aware and unaware of being videotaped. When the mothers were aware of being videotaped, they were more proximal to their infants, offered and demonstrated toys more frequently, engaged in more frequent interaction games, vocalized more frequently, emitted a greater number of words as well as declarative and imperative utterances, and their infants engaged in more constructive play. Combining the analysis of variance and correlational analyses results suggested that the verbal behaviors of mothers were inflated and their non-verbal behaviors were distorted when they were aware of being videotaped. The implications of these data for the use of videotaping as an assessment and intervention tool are discussed. 相似文献

Other-sex perceptions and actual reported behavior of 318 college males and 287 college females were compared for four dating situations. The average degree of inaccuracy (disregarding direction) for males was 29.0%, while for women it was 12.5%. Conclusions support other research indicating superior role-taking ability on the part of females. The issues of cultural transmission and pluralistic ignorance are discussed as they affect male and female interaction. Important research implications for human relations and the family in particular are noted. 相似文献

Especially remarkable seems the rarity of efforts to trace the evolution of the human intellect from that of the lower animals. Since Darwin's discovery, the beasts of the field, the fowl of the air and the fish of the sea have been examined with infinite pains by hundreds of workers in the effort to trace our physical genealogy, and with consummate success; yet few and far between have been the efforts to find the origins of intellect and trace its progress up to human faculty. And none of them has achieved any sure success. (Thorndike, 1911, p. 282) 相似文献

The effectiveness of an advice package designed to restructure the restaurant environment and encourage parent praise was examined. Experiment 1 assessed the usefulness of the package when used with experimenter assistance. Videotapes were used to record the target child's behavior. Pre-meal inappropriate behavior decreased an average of 51% across target children. Mealtime inappropriate behavior and parent praise and disapproval were also measured. Experiment 2 was designed to determine whether families could implement the package without experimenter assistance and whether effects obtained would generalize to a different restaurant. Data were taken in vivo. Nine families were randomly assigned to one of three groups. Group assignment determined the order in which families went to two restaurants, the number of dinners each family participated in, and the point at which parents received the advice package. The order in which the families went to the two restaurants as well as the number of baseline meals was counterbalanced. Results of Experiment 2 showed that, when using the advice package, parents in all sequences were able to decrease pre-meal inappropriate behavior of their children, and that these effects generalized to a second restaurant. 相似文献

Interpretations regarding the effects of exogenous and endogenous variables on endogenous variables in linear structural equation systems depend upon the convergence of a matrix power series. Convergence depends upon the eigenvalues of the structural coefficient matrix. The test for convergence developed by Jöreskog and Sörbom is shown to be only sufficient, not necessary and sufficient. 相似文献

The effects of task demands on the visual comparison of facial patterns and of comparable nonfacial patterns were explored in two studies. The studies yielded two primary findings. First, faces, despite their holistic properties, are not rotated faster than comparable non-face-like patterns, although subjects’ judgments of them were uniformly more rapid than judgments for nonfaces. Second, the nature of the same-different judgment task required of subjects had a large effect on the pattern of results obtained: When stimuli were compared to their mirror images, results indicative of mental “rotation” were obtained. When stimuli were compared on the basis of similarity of individual features, the pattern of results was very different. This one manipulation produced effects that exceeded those of all of the other manipulations, including that of rotation. 相似文献

The deterrent effect of capital punishment during the 1950s 总被引:1,自引:0,他引:1

This investigation examines the deterrence hypothesis of an inverse relationship between state execution rates and homicides. Although this question has received some attention in recent studies, the findings of these investigations are mixed. Cross-sectional analyses of states have typically shown execution and homicide rates to be positively associated, while at least two national time-series studies report support for the deterrence hypothesis. To test whether these divergent findings are result of the two different methodologies employed (cross-sectional vs. time-series), a methodology that combines the strengths of each is used in the present study. For the period 1950 to 1960, we examine cross-sectionally for states the relationship between changes in execution rates and changes in murder rates. This analysis does not find support for the deterrence argument for the certainty of the death penalty when a number of models of the execution rate--murder rate relationship are considered, and when a variety of imprisonment and socio-demographic factors are considered as control variables. 相似文献
