Pairing a Pavlovian safety signal (CS—) with a response prevention period was contrasted with other response prevention procedures to determine relative effectiveness for the elimination of learned avoidance behavior. After acquiring a one-way avoidance response, five groups of ten rats received various blocking or control treatments and were then compared on extinction performance. The four blocking treatments included blocking paired with a safety signal; blocking only; blocking paired with a novel stimulus; and blocking paired with a preexposed noncontingent tone. The fifth group served as a handling control. Compared to the handling control, all four blocking groups reached extinction criterion in fewer trials. Further, the safety signal group extinguished faster than the blocking only group or the blocking with noncontingent tone group. Results were viewed as an indication of the potential efficacy of pairing-conditioned fear-inhibiting cues with response prevention procedures for the elimination of fear-motivated behavior. Implications for behavioral therapy techniques were discussed. 相似文献

Phobies were asked to relate past events which they believed caused or contributed to their fear, and to describe cognitive events experienced while imagining phobic interactions. Approximately half the subjects were able to recall relevant learning experiences, with direct experiences far more common than vicarious experiences or learning based on verbal instruction. Almost all of the subjects reported self-verbalizations while imagining the phobic situation, in every case phobic relevant. However, in a minority of instances were the verbalizations ‘catastrophic’ in nature. In only about half the cases did the phobies report that, in vivo, thoughts preceeded fear in the phobic situation (in contrast to a comparison group of less fearful subjects for which thoughts did preceed fear to a significant degree). Results are discussed in terms of possible limitations of a cognitive interpretation of phobic behavior. 相似文献

An actor's belief in a proposition was inferred by both the actor himself and an observer on the basis of information concerning (a) the actor's preparation and delivery of a speech on the proposition to an unseen audience, and (b) the audience's belief in the proposition. The availability of this information to judges was systematically varied. The position advocated by the actor in his speech and the audience's opinion affected both the actor's belief in the test proposition and the belief attributed to the actor by a disinterested observer. However, neither effect depended upon whether or not other belief-relevant information was also available. These results were interpreted as more consistent with a summative model of information integration than with an averaging model. Actors' behavior had similar effects upon both actors' estimates of how the audience would judge their beliefs and observers' actual estimates of these beliefs. However, these effects were both greater than the effect of their behavior on their own estimates of their beliefs. The apparent strength of the audience's belief in the target proposition had a positive influence upon both actors' beliefs in the proposition and observers' estimates of actors' beliefs, but had a negative, or contrast effect upon actors' expectancies for how the audience would judge their beliefs. Results were more consistent with the differential perspective hypothesis of actor-observer differences proposed by Jones and Nisbett than with the hypothesis that actors and observers differentially weight the implications of their past experience in formulating their judgments. Results had additional implications for the assumptions that persons make when using their behaviors as indications of their beliefs. 相似文献

Different factors may affect reciprocity and attraction to an aid-giver. Sixty white South African high school students participated in a “record contest”. Hints provided by the quizmaster enabled them to win a prize. His help was expected or unexpected and, in providing this help, the quizmaster either did or did not violate a specific norm against doing so. It was predicted that recipients of unexpected help would display more reciprocity than recipients of expected help, but that the aid-giver would be derogated only when he behaved in both an unexpected and counternormative way and that, in general, attraction and reciprocity would be unrelated. These hypotheses were supported. They suggest that reciprocity is normally not mediated by attraction and that neither expectancy violation nor counternormative behavior will be itself produce derogation of an aid-giver. They further suggest recipients of unexpected help probably feel more obliged to repay an aid-giver than do recipients of expected help. 相似文献

The study breaks down the data from a preschool (mean age of students, 63 months) visual habituation experiment using a second-by-second analysis of the entire process, including fixation time and onsets for habituation and recovery trials and for each intertrial interval. The results parallel those suggested by Cohen, DeLoach, and Rissman (Child Development, 1975, 46, 611–617), for infants and are described using a two-process model of visual attention. 相似文献

Three postulates are proposed concerning the manner in which persons infer the validity of propositions that do not necessarily follow logically from the information available. These postulates assume that subjects first attempt to identify the propositions that are most and least likely to follow from the information given. They then use their beliefs in these propositions as anchors, relative to which the validity of other propositions is evaluated on the basis of both logical and nonlogical criteria. Two experiments are reported in which these postulates are used successfully to diagnose the logical and nonlogical factors that underlie inferences based upon both single statements and sets of syllogistically related propositions. The implications of the proposed postulates for existing formulations of social inference and cognitive organization are discussed. 相似文献

Two groups of six 3-month-old infants participated in a study which contained four consecutive 2-min periods. During Periods 2 and 4 both groups received adult social stimulation on the same prearranged schedule. The treatments during Periods 1 and 3 differed between the two groups; no adult was present for the A-S group, while the B-S group received the typical operant baseline (unresponsive adult treatment) for these two periods. Social stimulation caused a significant increase in vocal rate from the preceding control period for both groups. Infants in the A-S group vocalized at the same rate during the two periods in which the adult was absent and at similar rates during the two stimulation periods. For infants in the B-S group, baseline procedures suppressed vocal rates and did not provide a neutral or operant level of responding with which the effects of social conditioning could be compared. 相似文献

Internal and external subjects, who previously filled out Rotter's (1966) I-E scale, were asked to score the I-E scale of “another student”. Subjects were exposed to “an other's” score of either 0, 5, 10, 16, or 23, and were asked to rate themselves and the “other” on an evaluative questionnaire. It was predicted that ratings of the “other” would increase in positivity to the extent the “other” scored as an internal. A reverse direction was predicted for an index of negative evaluations. The predictions were confirmed. The results suggest that internal locus of control is a societal value. The findings did not support either Hannah's (1973) hypothesis that internals are more responsive to a need for social approval, or Byrne's (1969) similarity hypothesis. 相似文献
