Hemispheric processing, expressed as mean reaction time to various visual stimuli presented to the left and right visual fields, was investigated in eighteen stuttering and nonstuttering children. Tachistoscopic procedures were used to present linguistic stimuli (words and nonwords) as well as nonlinguistic stimuli (familiar and unfamiliar geometric figures) to the visual fields. Subjects responded by pressing a telegraph key when they perceived a real word or a familiar geometric figure. They were to make no response when they perceived nonwords or unfamiliar geometric figures. Faster reaction times were taken as an index of the most efficient or dominant hemisphere for a given task. No significant differences were found in mean reaction times for groups, visual fields, type of task, nor any of their interactions. Likewise, the data on accuracy also did not suggest that a larger proportion of stutters responded more accurately when linguistic stimuli were presented to the right hemisphere. Based on mean reaction times and on accuracy data, the stuttering and nonstuttering children performed with similar efficiencies and processing patterns. 相似文献

Sons of male alcoholics (SOMAs) are at markedly heightened genetic risk for the development of alcohol abuse. Study of SOMAs could therefore conceivably increase the efficiency of research aimed at uncovering those heritable factors that predispose to alcoholism. SOMAs manifest observable behavioral, cognitive, and psychophysiological abnormalities while sober and react idiosyncratically to alcohol intoxication. They are most commonly described as conduct disordered and hyperactive, appear heir to a variety of deficits in verbal and abstract cognition, and perform more poorly in the academic environment. SOMAs are characterized by abnormal patterns of cued psychophysiological response, and appear more sensitive to the putatively reinforcing aspects of alcohol intoxication. Various methodological weaknesses permeate the relevant literature. Some straightforward improvements are suggested. 相似文献

Sex differences are presented for the students of architecture and music, and the distribution of sex in the tested sample, and the population is discussed. The results are related to other studies in Scandinavia, which give comparable results. A genetic/cultural model is used to discuss the differences between results from Scandinavia, USA, and other parts of the world. 相似文献

Observers viewed one of nine dramatized videotaped interviews of a rape victim describing her rape. Information in the interview varied the prudence of the victim's behavior (careful, careless, no information provided) and the respectability of her character (good, bad, no information provided). Behavioral blame was significantly greater than characterological blame when the victim was careless or when no information was provided about behavior, regardless of the victim's character. When the behavior was careful, behavioral blame was equal in magnitude to characterological blame. In no case was characterological blame preferred. The adaptive value of behavioral blame for preserving a belief in a controllable and meaningful world was examined using a hierarchical multiple regression. After removing the effects of the prebeliefs of the subjects and the independent variable manipulations, only behavioral blame was significantly related to the maintenance of adaptive beliefs. Implications of the adaptive value of behavioral blame are discussed along with the importance of distinguishing observers' behavioral and characterological blaming strategies in the victimization literature. 相似文献

The literature relating to the influence of self-perception on the perception of others is reviewed. Projective effects are shown to occur in judgments of a wide range of psychological characteristics. Cognitive and dissonance theories of the projective process are critically examined. Drawing on the developmental literature, a cognitive theory of the projective process is proposed in which projective phenomena are conceptualized as side effects of a basic mechanism involved in knowing others. 相似文献

The role of early pattern components as cues in uncertain frequency detection was investigated in four probe-signal experiments. Listeners heard two consecutive presentations of one of two 12-tone patterns in a noise background. One presentation of the pattern was complete, whereas the other was missing the 11th (primary) tone. Listeners were required to indicate which presentation was complete. On 20% of the test trials, the 11th component of the complete pattern was replaced with one of four probe tones. The results indicated that listeners were more sensitive to the primary tone than to probe tones, and this selective sensitivity changed on a trial-by-trial basis as a function of the attentional cues provided by early pattern components. The data suggested two cue functions: (1) an “informational” function in providing information regarding which of two primary tones is likely to occur on a given trial, and (2) a “frequency” function that “automatically” directs listening to an appropriate frequency range and narrows or “fine tunes,” the listening band. 相似文献

In a series of experiments, the effects of reserpine, syrosingopine, and guanethidine on retention of a discriminated escape reversal training were investigated in mice. The peripherally and centrally acting reserpine produced amnesia while the primarily peripherally acting compounds, syrosingopine or guanethidine, did not produce amnesia even when given in high dosages or when training was given with low footshock. Unlike in the passive avoidance situation, peripherally administered norepinephrine or dopamine was not able to attenuate the reserpine-induced amnesia. The results were discussed in terms of the role of biogenic amines in memory formation. 相似文献

This study investigated the social context of self-injurious behavior in autistic, schizophrenic, and mentally retarded children residing in a state hospital. Social interactions between subjects and staff were recorded along with subjects' self-destructive behavior. The results showed a substantial increase in self-destructive behavior following the staff's presentation of demands, denials, and punishments in 19 of the 20 subjects. These results are consistent with the hypothesis that self-injurious behavior is a social behavior, which is determined by persons in the environment. In addition, the self-destructive behavior of one subject may have been largely self-stimulatory in nature. 相似文献
