AbstractOperant choice theories pose that behavior distribution between options is ruled by the consequences related with these options. Evidence suggests that rats’ performance is attuned to the affordances that the operant setting provides, such as lever height. Our aim was to explore in rats whether lever press distribution was influenced by the affordances furnished by two levers. Lever pressing was reinforced in two concurrent equal variable-ratio schedules of reinforcement, and in successive conditions lever height was varied asymmetrically—that is, one lever was higher than the other. Results showed a quadratic relation between response rates and lever height, a linear trend between preference and lever height, and higher between- and within-bout response rates on the lower lever in four out of the six pairs of lever heights assessed. These findings suggest that intermediate lever heights favored lever pressing with faster bout initiation and faster within-bout responding, and support the idea that preorganized properties of behavior (i.e., the organism’s abilities) interact with the environment before the operant contingency takes place. 相似文献

The Icelandic version of the Anxiety Sensitivity Index was investigated in two studies of college students. A principal components analysis of ASI scores from both studies (N=718) yielded three components similar to what has been found previously: Psychological Concerns, Physical Concerns and Social Concerns. In the first study the relationship between the ASI and trait anxiety was investigated. It was analysed at the level of the total scales but also at the level of subscales of both instruments. Two subscales of the STAI, measuring respectively Anxiety-trait and Depression-trait, were used as well as the Psychological Concerns and Physical Concerns subscales of the ASI. In a second study the relationships between ASI and its subscales and two symptom measures of anxiety and depression were addressed. ASI was in both studies more strongly related to the anxiety than the depression scales. Also, in both studies the Physical Concerns subscale of the ASI was more strongly related to anxiety than to depression, whereas the Psychological Concerns subscale was equally related to anxiety and depression. Taken together the studies support the notion of different relationships between different aspects of anxiety sensitivity, and anxiety and depression as traits, cognitive symptoms and mood related symptoms. 相似文献

Priming of visual search has a dominating effect upon attentional shifts and is thought to play a decisive role in visual stability. Despite this importance, the nature of the memory underlying priming remains controversial. To understand more fully the necessary conditions for priming, we contrasted passive versus active viewing of visual search arrays. There was no priming from passive viewing of search arrays, while it was strong for active search of the same displays. Displays requiring no search resulted in no priming, again showing that search is needed for priming to occur. Finally, we introduced working memory load during visual search in an effort to disrupt priming. The memorized items had either the same colors as or different colors from the visual search items. Retaining items in working memory inhibited priming of the working memory task-relevant colors, while little interference was observed for unrelated colors. The picture that emerges of priming is that it requires active attentional processing of the search items in addition to the operation of visual working memory, where the task relevance of the working memory load plays a key role. 相似文献

Would you find an opposite‐sex individual physically less attractive if you knew that he/she was a bad person? Would you feel the same if you were a man or a woman? This study examined whether gender differences exist in the influence of moral judgements on heterosexual physical attraction. In a first Experiment, participants (N = 214) rated on attractiveness photographs of opposite‐sex persons. Each photograph was paired with a “good” and a “bad” (from a moral point of view) sentence to depict a quality or activity of the displayed person (i.e., she/he is a defender of human rights in an NGO vs. she/he belongs to a terrorist group). Compared with women, men were significantly less influenced by sentence valence in their attractiveness ratings. A second Experiment (N = 105) using photographs of very attractive people showed the same pattern of results. The data suggest that sexual attraction is relatively less permeable to moral factors in men, and that this sex difference is consistent with an evolutionary approach to human sexuality. 相似文献

Background/Objective: Emotional intelligence is a variable which has been the subject of significantly increased research in recent years. Relationships have been shown with both physical and psychological problems. The aim of this study is to analyse the direct and indirect effect that emotional intelligence exerts over the manifestation of physical and psychological clinical symptomatology and to severe disorders such as burnout syndrome in a professional group in which social function is fundamental. Method: So that, 881 Latin-American catholic priests (Mage = 45.89; SDage = 11.58) were evaluated using the Trait Meta-Mood Scale-24, the Maslach Burnout Inventory-22 and the General Health Questionnaire-28. Results: Using path analysis, emotional intelligence, especially Attention and Emotional Clarity, shows a high effect on psychological and somatic issues. Conclusions: Thus, both specific disorders and general well-being are related to emotional intelligence. Providing effective emotional intelligence training sessions seems to be able to reduce possible physical and emotional disorders. 相似文献

What expressive facial features and processing mechanisms make a person look trustworthy, relative to happy? Participants judged the un/happiness or un/trustworthiness of people with dynamic expressions in which the eyes and/or the mouth unfolded from neutral to happy or vice versa. Faces with an unfolding smile looked more trustworthy and happier than faces with a neutral mouth, regardless of the eye expression. Unfolding happy eyes increased both trustworthiness and happiness only in the presence of a congruent unfolding smiling mouth. Nevertheless, the contribution of the mouth was greater for happiness than for trustworthiness; and the mouth was especially visually salient for expressions favouring happiness more than trustworthiness. We conclude that the categorisation of facial happiness is more automatically driven by the visual saliency of a single feature, that is, the smiling mouth, while perception of trustworthiness is more strategic, with the eyes being necessarily incorporated into a configural face representation. 相似文献

The main purpose of the present study was to examine implicit and explicit self-esteem (SE) in patients with persecutory delusions. In samples of paranoid patients, depressed patients, and healthy controls, implicit SE was assessed using the experimental go/no-go association task, whereas explicit SE was measured using 2 self-reporting questionnaires: the self-worth subscale of the World Assumption Scale (Janoff-Bulman, 1989) and the self-acceptance subscale of the Scales of Psychological Well-Being (Ryff & Keyes, 1995). Our analysis revealed that depressed patients showed lower explicit SE than did paranoid and healthy control participants. However, participants with persecutory delusions had significantly lower implicit SE scores than did healthy controls. We interpret the discrepancies observed between overt and covert measures in the paranoid group as psychological defense mechanisms. The present study stresses the clinical and theoretical importance of the use of implicit measures in psychopathology. 相似文献

Active brain areas and their temporal sequence of activation during the successful retrieval and naming of famous faces (KNOW) and during the tip-of-the-tongue (TOT) state were studied by means of low resolution electromagnetic tomographic analysis (LORETA) applied to event-related potentials. The results provide evidence that adequate activation of a neural network during the first 500 ms following presentation of the photograph--mainly involving the posterior temporal region, the insula, lateral and medial prefrontal areas and the medial temporal lobe--is associated with successful retrieval of lexical-phonological information about the person's name. Significant differences between conditions were observed in the 538-698-ms interval; specifically there was greater activation of the anterior cingulate gyrus (ACC) towards the supplementary motor area (SMA) in the KNOW than in the TOT condition, possibly in relation to the motor response and as a consequence of the successful retrieval of lexical-phonological information about the person. 相似文献

In addition to the negative effects of economic inequality on a range of health and social outcomes, we propose that inequality should also affect how people perceive the broader normative climate in society. We predicted that people living in a more unequal (vs. equal) society are more likely to appraise the social context as one where individualism determines people's behavior. We tested this idea in three experiments by manipulating the degree of economic inequality in a fictional society. We showed that, compared to the low-inequality condition, participants in the high-inequality condition were more likely to project individualistic norms onto society. Furthermore, Experiments 2 and 3 showed that in the high- (vs. low-) economic-inequality condition, participants inferred more competition and less cooperation between people. Our results are discussed in light of the importance of the perception of a broader normative climate to explain the consequences of economic inequality. 相似文献
