While much research concerning decision-making in interdependency situations concentrates on the influence of social values or different preferences for certain distributions of outcomes for self and other (McClintock, 1978), little attention has been paid to the cognitive processes underlying the expression of these different social values. The present research focuses on the cognitive processes by examining the influence of the dominant social values on decision-makers' response latencies (RLs) in interdependency situations. Using the Ring Measure of Social Values (Liebrand 1984), three experiments were conducted to assess these RLs. Experiment 1 examines the reliability of the social value construct and the RL effect. Experiments 2 and 3 investigate the generality of the RL effect across presentation of combinations of own and other's outcomes (all positive versus all negative). As predicted, RLs were shorter for individualists than for cooperators and competitors. Further, regardless of values, shorter RLs occurred across experiments when own outcomes are positive rather than negative. More important, the predicted interaction between social value and outcome distribution was observed, reflecting increasing RLs for cooperators as their joint outcomes decreased, longer RLs for individualists when own outcomes were negative rather than positive, and longer RLs for competitors when they were outcome disadvantaged rather than advantaged relative to other. These findings are consistent with the expectation that (I) the transformations associated with different social values require different cognitive processes, and (2) subsequent to the value transformations of outcomes, RLs increase when the utility of the transformed outcome distributions decreases.  相似文献

In studies reporting stimulus-reinforcer interactions in traditional conditioning paradigms, when a tone-light compound was associated with food the light gained stimulus control, but when the compound was paired with shock avoidance the tone gained control. However, the physical nature of the reinforcerrelated events (food vs. shock) presented in the presence of the tone-light compound was always confounded with the conditioned hedonic value of the compound's presence relative to its absence. When the compound was paired with shock, its presence was negative relative to its absence (which was shock-free). In contrast, when the compound was paired with food, its presence was positive relative to its absence (which was food-free). The present experiment dealt with this confounding effect by conditioning a tone-light compound to be positive or negative, relative to its absence, solely with food reinforcement. One group of rats received food for responding in the presence of the tone-light compound and no food in its absence. The other group also responded in the presence of the compound, but received food only in its absence. These rats were trained on a chained schedule in which responding in the presence of the tone-light compound produced a terminal link signaled by the absence of the compound; responding ceased in the terminal link because it delayed food delivery. In a test session to assess stimulus control by the elements of the compound, tone and light were presented separately under extinction conditions. Rats that had been exposed to a positive correlation between food and the compound emitted almost double the responses in the presence of the light as in the presence of the tone. In comparison, rats that had been exposed to a negative correlation emitted only two thirds as many responses in the presence of the light as in the presence of the tone. Because this selective association was produced using only food, it appears that the contingencies under which a reinforcer is presented, rather than (or as well as) its physical properties, can generate the selective associations previously attributed to “stimulus-reinforcer interactions.” This could mean that regardless of the class of reinforcer that ultimately maintains responding (appetitive or aversive), the contingency-generated hedonic value of the compound stimulus may influence the dominant modality of stimulus control.  相似文献

This article uses a case study to illustrate how a wider systems perspective can be helpful in considering the questions and dilemmas that arise in everyday practice when a practitioner is invited to intervene in a prescribed or limited way with an individual. The case is presented sequentially, with more detailed reflection at various junctures to allow readers to consider for themselves what the options for action are at any given point.  相似文献

WHEN MORE PAIN IS PREFERRED TO LESS:   总被引:10,自引:0,他引:10  
Abstract— Subjects were exposed to two aversive experiences: in the short trial, they immersed one hand in water at 14°C for 60 s; in the long trial, they immersed the other hand at 14°C for 60 s, then kept the hand in the water 30 s longer as the temperature of the water was gradually raised to 15°C, still painful but distinctly less so for most subjects. Subjects were later given a choice of which trial to repeat. A significant majority chose to repeat the long trial, apparently preferring more pain over less. The results add to other evidence suggesting that duration plays a small role in retrospective evaluations of aversive experiences; such evaluations are often dominated by the discomfort at the worst and at the final moments of episodes.  相似文献

Judgments ofsame anddifferent on a comparison task have been found to be subject to response competition if an irrelevant stimulus is presented in the display along with the target stimuli. For example, the reaction time for judging two letters the same is markedly increased if a different but irrelevant letter is also present in the display (C. W. Eriksen, O’Hara, & B. [A.] Eriksen, 1982). We have made use of this competition effect to map the visual attentional field in two dimensions. In two experiments, we varied the size of the attended area by varying the separation of the comparison stimuli. The boundaries of the attended area were mapped by varying the location of a response-competitive irrelevant noise letter. On this task, the attended area was found to be elliptical in shape, with the location of the target stimuli defining the major axis. The minor axis of the ellipse increased in direct proportion to increases in the major axis. Rather than interpret these field effects in terms of areas of enhanced processing, we propose that instead they represent the limits or failures in inhibition of competing stimulation.  相似文献

This study was a replication and extension of research by Foxx, McMorrow, Bittle, and Ness (1986) that assessed generalization effects of a social skills training program on the interactional behavior of adults with developmental disabilities. Target skills were a verbal action or reaction in six skill areas that specifically addressed the participants' skill deficits. In the present study, we trained 5 adult residents of a group home across these six skill areas using the “Sorry” game format and the scoring criteria described by Foxx et al. We extended the results of Foxx et al. by (a) using pretreatment assessment procedures to identify participants' specific skill deficits, (b) training all residents in the natural environment, (c) training participant—participant interactions, (d) training participants to respond to four of the six skill areas through the use of a role-play procedure, and (e) omitting rewards, criterion levels, and self-monitoring. Additionally, the trainer in the present study modeled correct responses only as an error correction procedure during training. Similar to those of Foxx et al., our results indicated that all participants increased their use of the trained interactional behaviors during the generalization assessments in the presence of other trained peers.  相似文献

This study examined the relative contributions of parental reports of child-related and parent-related stress to their estimates of expressive and receptive language skills on the Minnesota Child Development Inventory in 152 children referred to a communicative disorders clinic. Correlational analysis showed moderately high agreement between parental estimates and objective measures of expressive and receptive language ability. Multiple-regression analyses revealed that independent measures of language acquisition accounted for the greatest amount of variance in parental estimates of expressive and receptive language skills. Stressful child behavior accounted for a small but statistically significant proportion of the variance in estimates of expressive and receptive language skills. Parental stress, in contrast, did not contribute significantly to language estimates. These findings suggest that parents are able to formulate estimates of language development which are relatively independent of personal or child-related stressors.  相似文献

In two experiments, subjects recorded the frequency of occurrence of 12 classes of events each week for 3 months. During a final test they estimated frequency of occurrence of events either under time restrictions (Experiment 1) or difference priming instructions (Experiment 2). They also made (metamemory) estimates of the accuracy of their estimates. Time restrictions during an initial estimate did not affect the accuracy of frequency or metamemory estimation but a second estimate did increase accuracy. Priming instructions affected accuracy of metamemory estimates as well as the accuracy of estimates for high-frequency events. Metamemory error increased with event frequency.  相似文献
