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

Rats were trained on an eight-arm, elevated radial maze in a large cylindrical chamber where extramaze stimuli could be manipulated. The first experiment indicated that rats could use extramaze stimuli to locate the arms if such stimuli were available, whereas they performed less effectively and tended to employ response chaining if these stimuli were not available. The second experiment demonstrated that maze performance was disrupted by transposition of the stimuli but was relatively unaffected by rotation of the same stimuli. The third experiment suggested that the disruptive effect of stimulus transposition might be due to a “resetting” process elicited by the alteration in the configuration of the stimuli after stimulus transposition. These results suggest that when extramaze stimuli are available, rats tend to use such stimuli in a configurational manner to locate the arms rather than as a list of items processed independently of their spatial relationships to each other. 相似文献

Male subjects (N = 128) with high or low sex guilt either were or were not threatened with shock (fear arousal manipulation) and then viewed either an erotic or a neutral film (sex arousal manipulation). Then all subjects viewed and rated slides of attractive women and slides of landscapes (neutral control slides). If fear arousal was specifically transferred to sexual arousal as is often predicted rather than simply causing a general increase in arousal, then it would be expected that subjects who had been exposed to the threat would show high arousal in response to the slides of women and low arousal to the slides of landscapes, whereas subjects who had not been threatened would show low arousal to both the slides of women and landscapes. Physiological (pulse rate, skin resistance), self-report, and word association measures consistently indicated that (a) both of the arousal manipulations were effective, (b) the slides of women were arousing, (c) sex guilt influenced responses as would be expected from previous research, but (d) did not indicate support for arousal transference. These findings (a) provide information concerning the influence of guilt on drives, (b) raise questions about the transfer of arousal that was noted in less controlled investigations, and (c) highlight the need for additional controls in research of this type. 相似文献

This study was desinged to determine if motor deficits in limb apraxia are task specific. Non-brain-damaged patients and apraxic and nonapraxic patients with left hemisphere damage performed language and limb apraxia tests and six motor tasks with the left hand. Contrary to previous data, no significant group differences occurred on a finger tapping task. Although task complexity or sequencing requirements affected group differences, greatest apraxic impairment was noted on a task of precise steadiness, but only when its response inhibition requirements were increased. This pattern of deficits appears to be associated with greater involvement of the premotor area in the apraxic group. 相似文献

Left-right difference scores were analyzed for groups left- and right-handed subjects administered the same dichotic listening and visual half-tests on four separate days. The left-handed subjects showed greater test to test variability than the right handers for both modalities. 相似文献

Twenty speech pathologists measured total words and completed molar and molecular stuttering analyses from audio-recorded contrived samples of stuttered speech. Each subject completed a criterion referenced test prior to performing the experimental tasks. Analyses were performed under two conditions: Condition I consisted of samples presented at 100 wpm as recorded (nonexpanded); Condition II consisted of parallel samples recorded at 100 wpm as recorded (nonexpanded condition); Condition II consisted of parallel samples recorded at 100 wpm but presented at 59 wpm via a speech time expander. Results indicate that presentation of expanded samples (Condition II) significantly increased subject accuracy for the specific disfluency form-types word repetitions and part-word repetitions. Similar trends were noted for sound prolongations and hard contacts. Theoretical, experimental, and clinical implications are offered. 相似文献

The scores of several samples of male alcoholics and others on the MAC Scale (an MMPI-derived scale for the differentiation of male alcohol abusers from non-substance-abusing male psychiatric outpatients) are summarized, and the responses of the false negatives and false positives from the scale's standardization samples are analyzed. The following 7conclusions were reached: (1) There are two broad classes of male alcoholics—those who fall into the E + N + quadrant of secondary psychopathy and those who fall into the E - N + quadrant of neurotic introversion; (2) Unselected runs of male alcoholics populate these two quadrants in a quite stable ratio of 17 to 3, respectively; (3) Pari passu, Eysenck's placement of alcoholics in the E + N + quadrant will be upheld in approximately 85% of the cases while those who hold that alcoholics are ‘dysthymics who also drink too much’ will find themselves in error in approximately similar degree. 相似文献

An operant method of training enuretic children had previously been evaluated by direct training of the child and parent. A manual describing the method was used by 13 parents in the present study with no professional assistance. Bedwetting was reduced from its pre-treatment level of 68% of the nights to 27% during the first week. 10% during the third month and 7% the sixth month. These results closely approximated those obtained previously with direct training. 相似文献
