Many studies have explored the effects of single-word contexts on visual word recognition, and several models have been proposed to account for the results obtained. However, relatively little is known about the effects of sentence contexts. In the experiment reported, the contexts consisted of sentences with the final word deleted, and subjects made word-nonword (lexical) decisions on target strings of letters. Norms were collected to determine the most common completion for each sentence frame. The experiment yielded three main findings: (1) Lexical decisions were fastest for words that were the most common completions; (2) among words not given as completions in the norming procedure, decisions were faster for words related to the most common completions than for words unrelated to the most common completions; t3t also among words that were not produced as completions, decisions were faster for words that formed acceptable completions than for words that did not. These relatedness and sentence-acceptability effects were independent, so that the relatedness effect held even when the target words formed anomalous sentence completions. In order to account for these results, a model combining two types of processes is required. In the model described, schematic knowledge (Rumelhart & Ortony, 1977) operates upon a semantic network to activate particular nodes, and this activation spreads to related concepts as in the Collins and Loftus (1975) model. 相似文献

This study compared the efficacy of two treatment modalities (stress-reduction behavioral counseling and contingent nocturnal EMG biofeedback) on night-time bruxism. The 16 subjects (Ss) were assigned sequentially to one of four treatment groups: (1) stress-reduction behavioral counseling: (2) nocturnal biofeedback; (3) stress-reduction behavioral counseling and nocturnal biofeedback; and (4) waiting-list control group. A portable EMG unit was used to record the nightly total of electrical activity (?20 μV) from the masseter muscle 10 days before and after treatment. The three treatment procedures were found to be significantly superior to no-treatment control group. The outcome of the two treatments which made use of stress-reduction behavioral counseling, although better than the treatment which solely used nocturnal biofeedback, was not significantly better. This study demonstrates that stress-reduction skills learned while awake can have a generalized effect on stress-induced muscle activity during sleep. Implications for further research are discussed. 相似文献

There has been a serious lack of experimentally verified, effective dental hygiene programs in the schools. In and of themselves, the instruction-alone programs which comprise children's dental education do not produce proper toothbrushing skills. In the present study, a school-based contingency dental hygiene program designed to increase the effectiveness of children's toothbrushing skills at home was implemented with grade one and two classes. Each class was divided into teams and participated in the “Good Toothbrushing Game.” Each day four children from each team had the cleanliness of their teeth assessed according to the Simplified Oral Hygiene Index (Greene & Vermillion, 1964). The team with the lowest mean oral hygiene score was declared the daily winner. Winning teams received stickers and had their names posted. A multiple baseline across classrooms single-subject group design (Hersen & Barlow, 1976, pp. 228–229) established that the good toothbrushing game greatly increased the effectiveness of children's oral hygiene skills. The treatment terminal level for the grade one scores was 2.0 as compared to a baseline terminal level of 5.0, and for the grade two's was 2.3 compared to 5.7 at the end of baseline. A 9-mo follow-up indicated that these results were maintained. The data strongly suggest that proper implementation of behavioral principles is essential to the success of oral hygiene programs. 相似文献

Findings have been reported and replicated indicating group-induced caution at the racetrack and group-induced risk in blackjack gambling. The present research examined the effects of two consistent differences between the blackjack and racetrack situations: (a) the amount of money available to groups versus individuals; and (b) the number of bets made in the postbaseline session. It was found that group-induced caution can occur in the blackjack setting if groups have larger stakes than individuals, as was the case in the racetrack studies, and that this effect disappears over trials, due to group versus individual differences established in the previous blackjack studies. Since current explanations of choice shifts cannot account for the observed trial effects, it was suggested that traditional choice-dilemma material, on which these explanations are largely based, be examined for such effects. Implications of the possible outcomes of such an examination for current group polarization theory were discussed. 相似文献

Doctors' schedules are often overcrowded by unnecessary consultations with people complaining of minor or harmless symptoms. Such people typically decide to seek medical attention after hearing the opinions of family and friends. The present study explored some factors that might affect one's readiness to be influenced by nonprofessional opinions. Subjects in a role-playing setting were asked to imagine they were experiencing various symptoms, and then were given social comparison information suggesting they either should or should not see a doctor. As an orthogonal factor, subjects were also given an objective basis, via a simple physical test, for believing the symptoms either did or did not require medical attention. Consistent with Festinger's (1954) propositions, objective information suggesting the need to see a doctor eliminated the influence of social comparison. However, objective information suggesting the symptoms were harmless failed to reduce the impact of social comparison. These results indicate that providing an objective basis for deciding to sec a doctor will not be effective in controlling unnecessary visits, since "don't go" objective information is completely overridden by "go" social comparison information. 相似文献

A number of bipolar personality dimensions were investigated, some of which were selected a priori as being primarily concerned with interpersonal differences in skill (such as unintelligence-intelligence), and others of which were thought to describe differences in preferences (such as indoor-outdoor). Two findings emerged. First, persons at opposite poles of skill dimensions were assumed to possess differential role-taking ability: a skillful person was perceived as relatively more competent at portraying the opposite behavior than was an unskilled person. Second, attributions based upon skillful behavior tend to be less affected by contextual factors than attributions based upon unskillful behavior. An alternative interpretation of the results is discussed. 相似文献
