Acquisition of a unique cue in positive and negative patterning?   总被引:1,自引:0,他引:1  
Forty college students received a classical differential conditioning procedure involving both positive and negative patterning, each of these being associated with a different pair of stimuli. In positive patterning, elemental stimuli, A and B, were presented without an unconditioned stimulus while their compound, AB, was paired with electric shock. In negative patterning, elemental stimuli, C and D, were paired with shock while their compound, CD, remained unpaired. Thirty of these subjects then received a negative patterning transfer test on new stimuli, while ten subjects received a positive patterning transfer test. First interval response (FIR) and second interval response (SIR) were measured. During initial acquisition, positive patterning occurred in both dependent measures, but negative patterning was present only in the SIR. The transfer tests showed almost significant transfer of positive patterning in FIR and SIR. Negative patterning showed significant transfer neither in FIR nor SIR. It was concluded that, although elementary models of conditioning can explain positive patterning on the basis of summation of excitation from the elements to the compound, the occurrence of negative patterning in the SIR and the almost significant transfer of positive patterning in FIR and SIR appear to require the additional assumption of a unique cue.  相似文献

The isolation effect is a well-known phenomenon that has a well-accepted explanation: An item that is isolated on a list becomes perceptually salient, which leads to extra rehearsal that enhances memory for the isolate. To evaluate this hypothesis, the authors isolated an item near the beginning of a list. Immediately after each item was presented for study, participants judged the likelihood of recalling the item. Although the isolation effect occurred, participants did not judge the isolate as being more memorable than the preceding item, suggesting that the isolate was not salient. In a second experiment, participants rehearsed items aloud. Isolation at the beginning of the list did not produce extra rehearsal. By contrast, isolation in the middle of the list produced extra rehearsal; however, even when the isolate did not receive extra rehearsal, an isolation effect was evident. Thus, salience and extra rehearsal are not necessary for producing an isolation effect.  相似文献

A considerable amount of meta-analytic research supports the effectiveness of cognitive–behavioral psychoeducational programs in reducing recidivism rates, in youths and adults with antisocial behavior. These same studies suggest that programs including a cognitive component are as twice as more effective in reducing recidivism rates. This paper reviews outcome studies sustaining the use of structured interventions in forensic settings. It introduces a new program, Growing Pro-Social (GPS), currently in use in several Portuguese youth rehabilitation centers and prisons. GPS is a multimodal structured group program designed for the rehabilitation of individuals with antisocial behavior. It includes 40 weekly sessions, organized into 5 sequential modules. Based on a cognitive–interpersonal theoretical framework, GPS focuses on cognitive, emotional, and behavioral change, assuming as an ultimate goal the modification of dysfunctional core beliefs underlying antisocial behavior.  相似文献

Children with Syntactic Specific Language Impairment (S-SLI) have difficulties understanding object relative clauses, which have been ascribed to a deficit in syntactic movement. The current study explores the nature of the deficit in movement, and specifically whether it is related to a deficit in the construction of syntactic structure and traces, or whether the structure is constructed correctly but the transfer of thematic roles from the trace is impaired. This question was addressed using reading aloud and paraphrasing of object relatives that included noun-verb heterophonic homographs after the trace. Because the correct reading of homographs as noun or verb critically hinges on the identification of their syntactic position, readers who cannot construct traces are expected to read homographs incorporated after the trace incorrectly. The participants were 15 Hebrew-speaking children aged 9.3 to 14.6 with S-SLI and 50 typically developing children. The children with S-SLI read the homographs after the trace correctly but failed to interpret the object relatives, making thematic role errors. The results suggest that in S-SLI, at least for school-aged children, syntactic structure and traces are created, but the assignment of thematic roles from the trace to the moved element is impaired, leading to a deficit in the comprehension of movement-derived sentences.  相似文献

Previous research has shown that people respond with greater sensitivity to negative stereotypical comments about a group that are made from someone outside the group in question than from someone who belongs to the group. In this paper, we investigated if the same effect occurs in response to comments made about stigmatized groups. Specifically, we examined how people react to comments made about the mentally ill. The conditions under which people accept or reject stereotypes of the mentally ill may shed light on the conditions necessary for effective anti-discrimination campaigns. In the current study, participants responded to positive or negative stereotypes of the mentally ill voiced by either someone who has, or has not, suffered from a mental illness. Participants were more sensitive, agreed less, and evaluated the speaker less favourably when comments came from the out-group rather than the in-group source. The effects were strongest for negative comments, however contrary to previous research participants also responded less favourably to positive comments from the out-group source. These reactions were mediated by the perceived constructiveness of the speaker's motives. Implications for the effectiveness of anti-discrimination campaigns are discussed.  相似文献

The present study examined whether positive specific memory recall improves mood more than overgeneral memory recall. Moreover, this study examined the mood contrast effect in subclinically depressed participants. The mood contrast effect refers to when people ruminate on discrepancies between the current self and a past ideal self by recall of positive self-discrepant (low self-concordant) memories and thereby, fall into a negative mood. Undergraduate students (N?=?161) underwent a negative mood induction, and then concentrated on positive specific memory recall, positive overgeneral memory recall, or distraction. Results showed that there were no group differences in mood repair. Nevertheless, recalled memory self-concordance was associated with sad mood repair in the specific memory group, and moreover, this effect was not significant in people high in depressive symptoms. We discussed the results of mood repair effect from the perspective of baseline negative mood in subclinical depression.  相似文献

This study investigated the face inversion effect in rhesus monkeys (Macaca mulatta). Face stimuli consisted of ten black-and-white examples of unfamiliar rhesus monkey faces, brown capuchin faces, and human faces. Two non-face categories included ten examples of automobiles and abstract shapes. All stimuli were presented in a sequential matching-to-sample format using an automated joystick-testing paradigm. Subjects performed significantly better on upright than on inverted presentations of automobiles, rhesus monkey and capuchin faces, but not human faces or abstract shapes. These results are inconsistent with data from humans and chimpanzees that show the inversion effect only for categories of stimuli for which subjects have developed expertise. The inversion effect in rhesus monkeys does not appear to be face-specific, and should therefore not be used as a marker of specialized face processing in this species.

The attentional blink (AB) effect is characterized by a failure to detect a second target following the identification of a previous target in a RSVP stream. This effect has been attributed to capacity limitations at a central level of visual information processes. Postperceptual models suppose that the AB locus is located in short-term memory. To test this hypothesis, we investigated the influence of a short-term memory deficit on the AB effect in a patient with such a deficit. The three main results of this study are (1) the persistence of an AB effect, (2) a large number of T1 missed identifications and (3) a T2 detection deficit for a specific delay (367 ms). These results indicate that a short-term memory deficit disrupts the processing of each target (T1 and T2) but does not product an abolition of the AB effect.  相似文献

Affective evaluation of stimuli just seen in visual search tasks has been shown to depend on task-relevant stimulus configuration (Raymond, Fenske, & Tavassoli, 2003): Whereas targets and novel stimuli were evaluated similarly, distractors were devaluated. These results were explained by an inhibition-based account of the influence of selective attention on emotion. In the present experiments, we demonstrated that stimulus devaluation might not be a consequence of attentional inhibition. By simply instructing participants to react to an accepted or rejected stimulus in the visual search task of Experiment 1, we found distractor devaluation in the first case and target devaluation in the second case. We conclude that devaluation of stimuli is mediated by the affective connotation implied by response labels and instructions. This was confirmed in Experiment 2: To-be-ignored stimuli were not devaluated when participants knew that those stimuli would become task-relevant during the experiment.  相似文献

Competence, morality and sociability dimensions have shown to be essential to measure stereotypes. Theoretically, the attributes associated with the negative pole of morality are more reliable and have shown to have higher evaluative weight. However, the current research usually employs only positive attributes to measure each dimension. Since the advantages of the inclusion of negative morality are clear it would be interesting to know about the effects of the inclusion of such type of attributes (i.e., it is good or bad for the measurement). The purpose of this study is to examine if the addition of negative items makes possible to improve the stereotype content measures. This study compares the differences between scales with various compositions of positive and negative items of stereotypes to predict three related variables: anger, fear and a semantic differential of evaluation. The study was carried out with a sample of 550 Spaniards. The data found highlights the importance of using attributes of the negative pole of morality in studying stereotypes. Their use was able to explain the intergroup emotional responses and the semantic differential more efficiently.  相似文献

Dialogue and debate regarding the definition of prevention has subsided and has been replaced by research and information regarding pathways to dysfunction and effective primary prevention strategies. In spite of the solid research base and the strong desire of practitioners to apply prevention strategies, there continues to be sporadic implementation in schools. Barriers to the implementation of primary prevention programs include traditional professional practice within psychology, lack of communicating pertinent information between professions and policymakers, commitment of resources, and limited understanding of the pathways to successful and widespread implementation. Recommendations to address these barriers are discussed.  相似文献

Two experiments were performed to replicate and extend previous findings of judgmental bias which favors physically attractive people. In the first experiment male and female subjects judged an essay purportedly written by an attractive or an unattractive female author. The attractive author was rated as significantly more talented by male judges. Female judges rated the attractive author as less talented, although this difference was not statistically significant. A second experiment concerned ratings by males and females of essays written by attractive or unattractive male authors. The results suggested that the attractiveness halo effect does not occur for male authors.A similar version of this article was presented at the meeting of the Western Psychological Association, Los Angeles, April 1976. Thanks are due to Jan Ault, Lynn Barrett, Paul Leathem, Mike Orenich, Bill Starns, and Meg Wiedlin for their participation in various stages of the research.  相似文献

Forty normal subjects (20 left-handed; 20 right-handed) were submitted to a proprioceptive straight ahead pointing task while blindfolded to study the effect of the hand used and of the hand preference on the estimation of the subjective sagittal middle. Results showed that left-handed and right-handed subjects both deviated to the left of the objective sagittal middle and presented an effect of the hand used and of the starting point affecting their straight ahead performance in a similar way. In all subjects whatever their manual preference, using the left hand and starting 30 degrees to left induced a tendency to deviate to the same side, whereas using the right hand and starting 30 degrees to right induced a tendency to place the subjective middle to the right of the objective middle. These results are interpreted with regard to the hypothesis of a cortical control of the position of the egocentric reference.  相似文献

Using the dualistic model of passion [Vallerand, R.J., Blanchard, C.M., Mageau, G.A., Koestner, R., Ratelle, C.F., Léonard, M.,?…?Marsolais, J. (2003). Les passions de l’âme: On obsessive and harmonious passion. Journal of Personality and Social Psychology, 85, 756–767], this research represents an initial attempt to examine whether an activity that is generally recognized to have widespread benefits, namely yoga, can still relate differently to outcomes as a function of the type of activity involvement (i.e., passion). Vallerand et al. (2003) distinguish two types of passion: harmonious passion, characterized by a volitional engagement in a beloved activity, and obsessive passion, which entails an uncontrollable urge to partake in the activity. Study 1 (n?=?75) revealed that harmonious passion for yoga was more positively associated with positive psychological outcomes than obsessive passion. In Study 2 (n?=?89), these findings were replicated and extended using a 3-month prospective design. Although preliminary, the results of this research suggest that the type of passion one has for a ‘positive’ activity makes a difference for one's psychological and physical well-being.  相似文献

The SNARC effect refers to the association of smaller numbers with the left and of larger numbers with the right side of extracorporal space (Dehaene, Bossini, & Giraux, 1993). We tested the assumption that, in addition to these associations, numbers are also related to participants' hands. We report two experiments with vertically arranged buttons in which the nature of the SNARC effect depended on whether the task set was button or hand related: In the first case, a vertical location-related SNARC effect occurred, whereas in the second a hand-related SNARC effect was found. Our third experiment confirmed that space-related number representations dominate the SNARC effect when the buttons are arranged horizontally. We concluded that both effector- and space-related number representations can influence and modify the SNARC effect.  相似文献

In Experiments 1 and 2, after studying a list containing connotatively neutral words that were presented once or were presented at various spacing intervals, subjects either attempted free recall or made affective judgments of the study-list targets along a pleasant/unpleasant dimension. Spacing effects occurred in recall, and massed items were judged to be more unpleasantthan once-presented and spaced words. In the third experiment, subjects studied homogeneous lists composed of either connotatively good words or connotativelybad ones. Spacing effects were absent in the recall of both types of words because massed-practice words were recalled at a high level, one that was about the same as that for spaced-practice words. Affective judgments were unrelated to presentation condition, and both good and bad massed words were judged to be positive in affect. Although the data suggest that different study conditions can lead to different affective reactions, the results are moot with regard to the relationship between affect and the magnitude of spacing effects.  相似文献
