This study examined the relationship between illusory changes of repeated words (“verbal transformations” or VTs) and illusory presence of phonemes replaced by noise (“phonemic restorations” or PhRs). Separate groups of 20 subjects were each presented with one of four taped variations of the repeated stimulus word “magistrate”: stimulus intact (MAGISTRATE); speech sound “s” removed and replaced with a silent gap (MAGI TRATE); speech sound “s” removed and replaced with a louder extraneous sound (MAGI1TRATE); syllable “gis” removed and replaced with a louder extraneous sound (MA71TRATE). The stimuli MAGI1TRATE and MA71TRATE evoked PhRs, and with these stimuli, the phonetic changes corresponding to VTs were concentrated at the perceptually restored portions of the word. It is suggested that both PhRs and VTs are related directly to perceptual processes employed normally for the correction of errors and resolution of ambiguities in speech. Other effects of PhRs upon VTs are described and implications of these findings for mechanisms underlying speech perception are discussed. 相似文献

Two experiments investigated characteristic generalized imitation procedures on a nonimitative successive visual discrimination task. In Experiment I, no discriminative behavior was obtained though a number of procedures designed to enhance discrimination were employed. The introduction of a differential modeling procedure after nine or 10 sessions of nondifferential performance was ineffective in producing differential responding for three of four Ss. In the second experiment, the differential modeling procedure was introduced as an initial manipulation and was successful in establishing discriminative performance in all Ss. After several sessions of differential responding, the observation of a model performing nondifferentially was relatively ineffective in altering the pattern of responding. These results suggest (1) that modeling may be functional in altering a S's behavior depending on what point in the procedures the manipulation is introduced and (2) that certain procedural variables may define a functional response class characterized by the failure to develop discriminative responding. 相似文献

If all of mankind is to have an adequate diet, we must both stabilize world population and increase markedly world food supply. Moreover, attaining any such increase in food supply may be as much a problem in vocational psychology (e.g. the skill, knowledge, openness to change, and motivation of farmers) as in agricultural technology. The purpose of this review is to further psychological work on agricultural productivity by listing and evaluating a cross-section of relevant articles since 1945. Because psychologists have largely ignored agriculture, most reviewed studies were conducted by other behavioral scientists. Studies are grouped according to three broad areas: (1) predictors of choice, success, and satisfaction; (2) adoption of recommended practices; and (3) communal agriculture. 相似文献

This investigation represents an attempt to develop and validate a research instrument (Manifest Needs Questionnaire) capable of measuring the four needs of achievement, affiliation, autonomy, and dominance using behaviorally-based scales. The instrument is designed to measure such needs with specific reference to work settings and with minimal time requirements for completion. Results of both laboratory and field studies among 640 subjects indicate that the instrument exhibits acceptable levels of convergent, discriminant, and predictive validity, as well as reasonably high test-retest reliability and internal consistency. Results are compared to other, lengthier instruments designed to measure similar needs. 相似文献

Silverman, Frank and Dachinger (1974) found support for their hypothesis that the effectiveness of systematic desensitization (SD) resides in its activation of unconscious, merging fantasies. Their subjects were subjected to a variant of SD. in which a procedure aimed at stimulating a fantasy of ‘merging with mother’ was substituted for muscle relaxation. This pro- cedure consisted of the tachistoscopic subliminal exposure of the symbiotic gratification stimulus mommy and i are one(experimental) or neutral stimulus people walking (control). The aim of the present study was to replicate their work with special reference to demand characteristics. using as subjects snake phobics. SD with a symbiotic gratification stimulus was not more effective than SD with a neutral stimulus, which may be explained by the fact that the neutral stimulus in the present study snake and I are one was more relevant than the neutral stimulus in the Silverman et al. study. Moreover, subjects with a therapy-set improved significantly more than subjects with a research-set. 相似文献

While previous research has indicated that certain situational variables can mediate the typical positive relationship between attitudinal similarity and attraction, investigations focusing on the impact of individual difference variables on this relationship have typically yielded unimpressive results. The present experiment was conducted to test the prediction that individual differences in sensation seeking do moderate this relationship. The major results showed that, as predicted, high sensation seekers were more attracted than low sensation seekers to dissimilar others, whereas low sensation seekers were more attracted than high sensation seekers to people with similar attitudes. The data also indicated that a misattribution of arousal manipulation serves to increase attraction under certain conditions. Specifically, misattribution of aversive arousal increased low sensation seekers' attraction to a dissimilar stranger and increased high sensation seekers' attraction to a similar stranger. 相似文献
