The ability to think of a previously studied item has often been shown to be impaired when, in one way or another, the extraitem context is changed from study to test. In a series of five experiments, such impairment is induced in a somewhat different way. A fragment (e.g. r-i--rop) of a just-studied word (raindrop) is shown to be less readily completed if it is presented bit by bit (r------p, r----r-p, r-i--r-p, r-i--rop) rather than all at once (Experiments 1, 3, 4, and 5). No such effect is found if the word has not been studied beforehand (Experiments 2, 3, 4, and 5). This pattern of results occurs even when fragments of studied and nonstudied words occur in the same test and under conditions in which subjects cannot tell whether a given fragment is of a studied or nonstudied word (Experiments 4 and 5). In addition, for words that have been studied beforehand, the impairment is shown to increase systematically with the number of steps involved in the presentation of the word fragment (Experiment 3) and also to persist when the time allowed for completion of the final version of the fragment is increased from 4 s to a full minute (Experiment 5). 相似文献

Factors affecting spontaneous alternation behavior (SAB) in animals, for example, age, gender and species studied; type of
apparatus and cues employed; and neuro-anatomical, neuro-chemical and motivational status of the organism, were reviewed.
Despite a myriad of experiments showing interesting main effects of such variables, little research has been performed assessing
the interactive affects of these factors on alternation behavior. For example, psychologists test rats in central nervous
system (CNS) lesion studies, whereas psychopharmacologists tend to assess SAB in mice. Most importantly, studies have not
been reported investigating the possible interactions among species, brain lesions and drugs. This is an unfortunate omission
since several important alternation models include propositions relating to cholinergic and/or serotonergic coding in the
hippocampus. Examination of behavioral studies revealed the primary cue for alternation among invertebrates to be body turn,
whereas vertebrates rely primarily on directional and odor cues. Reference to the seeking of stimulus change remains the most
compelling motivational account of why animals manifest this ubiquitious and reliable behavior pattern.

This study examined changes in cognitive-dissonance-related variables during the professional training period. Differences in levels and change in satisfaction with career choice, importance of career, certainty of career decision, self-occupational perceptions, general attitude toward career, time since career decision, and past experience were observed when students who left a collegiate professional training program before program completion were compared with those who remained in the program. Data supports the validity of D. Hershenson and R. Roth's (1966, Journal of Counseling Psychology, 13, 368–370) and V. Harren's (1979, Journal of Vocational Behavior, 14, 119–133) theoretical models of vocational decision and the Assessment of Career Decision Making scale. 相似文献

Dr. Henry Freund was one of the foremost authorities on stuttering in Europe, and his contributions on the psychology of the disorder continued after emigrating to this country. He was a neurologist and psychiatrist, as well as a speech pathologist. He died in 1982, and in this posthumous paper he describes his career and personal experiences, while undergoing therapy from the most famous European speech pathologists of his time. He also offers some cogent comments about current therapies and future needs. 相似文献

The present study explored individual differences in performance of a geometric analogies task. Whereas past studies employed true/false or two-alternative items, the present research included four-alternative items and studied eye movements and confidence judgements for each item performance as well as latency and error. Item difficulty proved to be a function of an interaction between the number of response alternatives and the number of elements in items, especially for subjects lower in fluid-analytic reasoning ability. Results were interpreted using two hypothesized performance strategies: constructive matching and response elimination. The less efficient of these, response elimination, seemed to be used more by lower ability subjects on more difficult items. While two previous theories resemble one or the other of these strategies, neither alone seems to capture the complexity of adaptive problem solving. It appears that a comprehensive theory should incorporate strategy shifting as a function of item difficulty and subject ability.Componential models, based in part on past research, revealed that a justification component was activated and deactivated depending upon the nature of the analogy being solved. In addition, two new components, spatial inference and spatial application, were identified as important on some items, suggesting that different geometric analogy items invoke different cognitive processing components. Thus, a comprehensive theory should also describe component activation and deactivation. 相似文献

The effects of a graduated prompting treatment procedure were analyzed in three phases of an experiment on the training and generalization of reaching-grasp responding in 2- to 4-year-old blind, severely or profoundly retarded children. In Phase 1, we used a multiple-baseline across-subjects design to investigate the effectiveness of the treatment on midline reach-grasp responding. In Phase 2, we used a reversal design to investigate the effects of repeated implementations and withdrawals of the treatment. In both phases, generalization to right and left positions was measured. In Phase 3, in a multiple-baseline across-responses design, the treatment was implemented in right and left positions. Also in Phase 3, shift of stimulus control from toy-sound to verbal instructions was measured. The results showed that (a) the graduated prompting procedure was effective in training reach-grasp responding in all three children; (b) for one child, the effects were durable over repeated applications of the treatment procedure, but were not maintained during withdrawals; (c) for another child, the treatment procedure was effective in teaching reach-grasp responding in all three positions; and (d) for the same child, training of reach-grasp responding generalized to toys presented without sound, given only the verbal instruction. 相似文献

Five-year-old children were tested for perceptual trading relations between a temporal cue (silence duration) and a spectral cue (F1 onset frequency) for the “say-stay” distinction. Identification functions were obtained for two synthetic “say-stay” continua, each containing systematic variations in the amount of silence following the /s/ noise. In one continuum, the vocalic portion had a lower F1 onset than in the other continuum. Children showed a smaller trading relation than has been found with adults. They did not differ from adults, however, in their perception of an “ay-day” continuum formed by varying F1 onset frequency only. The results of a discrimination task in which the two acoustic cues were made to “cooperate” or “conflict” phonetically supported the notion of perceptual equivalence of the temporal and spectral cues along a single phonetic dimension. The results indicate that young children, like adults, perceptually integrate multiple cues to a speech contrast in a phonetically relevant manner, but that they may not give the same perceptual weights to the various cues as do adults. 相似文献

Politicians sometimes shift the stances that they take on issues. An experiment investigated the effect of such a shift upon observers' perceptions of and feelings about an ostensible candidate for public office. The target issue (private ownership of handguns) was chosen as being relatively emotional for some subjects and unemotional for others. Subjects were also selected (independently) as being either pro or con on the issue. The position taken by the stimulus person (who, in contrast to previous research, was identified as a candidate for office) was portrayed as initially being either similar or dissimilar to that of the subject. An assessment of the candidate's position 6 months later indicated either no change or a reversal of the initial position. Subjects' evaluations of the candidate on a variety of dimensions yielded a consistent pattern. The combination of initial agreement and final agreement was viewed more favorably than any other combination. Taken together, the data suggest two conclusions. First, there was no support in this context for the notion that a shift from disagreement to agreement would be especially valued (i.e., there was no “gain” effect). Second, in the realm of politics, people value consistent agreement with their own position—but they do not reward consistency per se. 相似文献

This project, utilizing a pretest and posttest design, studied interactions between co-therapists and the relationships of their interactions to client outcome. Six co-therapist pairs at a counseling center saw two clients in multiple treatments yielding twelve cases. The study investigated co-therapist relationships in regard to: (a) their level of mutuality or caring for their partners, (b) their ratings of the quality of their relationships, and (c) their agreement as to perceptions and behavior during sessions. Also investigated were: the relation of co-therapist interaction to client outcome and the personal growth of the therapists over the course of therapy. Results supported success claims of the literature concerning co-therapy. 相似文献
