A test of simple pantomime was administered to three groups of adults and comparisons were made across groups of the incidence of subjects who exhibited body part as object (BPO) responses and of the mean frequency of occurrence of BPO in each group. The three groups were left-hemisphere-damaged aphasics (N = 28), right-hemisphere-damaged (N = 24), and normal controls (N = 28). The results indicated no significant differences among groups on the BPO measures. Also, to test the strength of association between the frequency of occurrence of BPO and measures of limb apraxia and severity of aphasia for the left-hemisphere-damaged aphasic group, correlation coefficients were obtained. The correlations were low and nonsignificant. The results of this investigation do not support the common clinical assumption that the occurrence of BPO during the performance of simple pantomimes is pathognomic for left-hemisphere pathology or associated with limb apraxia. 相似文献

Formal processes (especially metacognitive or control processes) involved in complex human problem solving are examined in a game-playing situation with one person pitted against a microcomputer algorithm. In particular, the strategy of second-guessing is simulated in real-time in an attempt to outwit the person in a binary prediction paradigm. Aspects of success and failure are suggested. A working implementation in BASIC for a TRS-80 Level II is provided. 相似文献

A new mathematical procedure (BIDALGO) is suggested for application to the psychological testing field. BIDALGO, similar to past adaptive testing methods, is compared both with MMPI short-form efforts and applications in the educational testing literature. A comparison is also made between linear regression models used in past efforts and the Bayesian decision models used in BIDALGO. The requirements for an MMPI application are delineated, emphasizing branching procedures for specific scales and difficulties expected in achieving code-type congruence. Work in progress of applying BIDALGO to the depression scale and the full MMPI is also described. 相似文献

Although there has been increased reliance upon the direct physiological measurement of penile tumescence in the assessment of sexual deviations, the reliability of these measures has never been empirically validated. This investigation evaluates the reliability of the rape index as a technique in differentiating rapists from nonrapists. Eighteen individuals incarcerated on non-sexual-related offenses were presented visual and audio stimuli depicting mutually consenting intercourse, rape, and aggression. These stimuli were presented under two instructional sets: (1) enchance arousal and (2) suppress arousal. Reliability indices for the rape index were computed among various conditions of modality presentation, instructional set, and test-retest conditions. The overall reliability of the rape index was found to be low. The implications of these results upon the assessment and classification of offenders is discussed. 相似文献

A machine language technique is described whereby the Z-80 microprocessor of the Model III TRS-80 can be programmed to monitor position of the electron beam during CRT scanning. This technique provides the opportunity to synchronize the appearance of video displays with Z-80 processing. The programmer can therefore be assured of crisp stimulus displays and precisely recorded reaction times. The computer’s real-time clock operates on video circuitry as part of a routine that is initiated by a maskable interrupt. The real-time clock interrupt can be vectored from its normal use to a routine that signals the Z-80 when the electron beam is at a known screen location. A machine language program and a TRSDOS BASIC program that demonstrate the technique are described. 相似文献

This paper describes an all-purpose experimental system, “APES,” for use in a microprocessor-controlled behavioral pharmacology laboratory. APES is an assembly language program that can run on any of the DEC PDP-11 family processors under an RT-11 single-job operating system. Its main purpose is the real-time control of psychological experimentation. The capabilities of the system are: (1) system generation of all operant or Pavlovian conditioning paradigms, (2) collection and storage of both behavioral and physiological data in a machine-readable format for later statistical analysis, and (3) operation that can be accomplished by individuals who have no computer programming experience. 相似文献

The effects of a salient self-schema on message evaluation were studied. Subjects were identified who characterized themselves using trait adjectives that reflected the prototype of either a “religious” or a “legalistic” person. Equally persuasive sets of proattitudinal messages were developed empirically using weak arguments. Half of the messages were developed to reflect a “religious” perspective on the issue (capital punishment, abortion) whereas half were developed to reflect a “legalistic” perspective on the issue. Religious and legalistic subjects were then exposed to religious or legalistic arguments supporting an equally acceptable position (e.g., eliminating capital punishment). Afterward, subjects evaluated the persuasiveness of the communication and listed their thoughts as part of a “curriculum development project.” Results suggested that subjects when exposed to a schema-relevant message arguments for a position in which they believed were more positive about the quality of the message arguments and in their cognitive responding. These data extend the heuristic value of selfschemata to the area of attitudes and suggest that cognitive responses in persuasion are subjectively rather than objectively rational. 相似文献

Two single-subject experiments were conducted in public school classrooms for severely emotionally disturbed children. Both experiments investigated the effects of a treatment requiring a child to exhibit a simple exercise task after a verbal or aggressive response, using reversal and multiple-baseline designs. The independent variable, contingent exercise, required standing up and sitting on the floor five to ten times contingent on an inappropriate behavior. It was found that contingent exercise was easy to carry out, and following it, the child quickly returned to the learning task that had been interrupted by the inappropriate behavior. The contingent exercise procedure required a minimum of prompting or manual guidance. Although contingent exercise was not topographically related to the inappropriate response, it decreased those responses dramatically. The results suggested that contingent exercise was not only more powerful than DRO but also could be administered independently. It was concluded that contingent exercise may constitute an alternative procedure that can be used by therapists confronted with severely abnormal behaviors. It would appear to be particularly relevant in settings where procedures such as timeout and painful consequences find restricted use. Finally, a number of guidelines have been proposed as a safeguard against the misuse of this mild but powerful procedure. 相似文献
