In two experiments, participants were exposed to a listing of actions performed by a fictitious Mr. X, over three days of his life. For most of his actions an outcome was described, but some were not followed by any outcome. On Day 3, Mr. X performed an action (the target action) that was followed by a novel outcome. For participants in the control condition, the target action that preceded the appearance of this outcome was also novel; for participants in the latent inhibition (LI) condition, Mr. X had performed the target action on repeated occasions during Days 2 and 3, without it producing any outcome. All the participants were tested on their ability to retrieve the action performed by Mr. X prior to the target outcome. In Experiment 1, retrieval of the target action (indicating a less effective target action–outcome association) was poorer in the LI than in the control condition. In Experiment 2, reducing the proportion (the density) of nontarget actions that brought outcomes during initial training was found to reduce the size of the LI effect. These results are predicted by the account of LI put forward previously [Hall, G., & Rodríguez, G. (2010). Associative and nonassociative processes in latent inhibition: An elaboration of the Pearce-Hall model. In R. E. Lubow & I. Weiner (Eds.), Latent inhibition: Data, theories, and applications to schizophrenia (pp. 114–136). Cambridge, England: Cambridge University Press]. A high density of predictive relationships ensures strong activation of the expectancy that some outcome will occur when the target action is first presented; this facilitates the formation of a target action–no-event association during training in the LI condition, thus enhancing the LI effect. 相似文献

This article proposes an integrative framework for understanding the accuracy and inaccuracy of stereotypes. Specifically, we highlight research issues and traditions from social and personality psychology that do not often intersect, but which can be mutually informative. Within this framework, the social psychologist's interest in the accuracy of group stereotypes is conceptually much like a personality psychologist's interest in the accuracy with which perceivers can identify types of individuals, for example extraverts. Both fields make use, implicitly or explicitly, of personal attributes and behaviors (cues) in assessing accuracy of beliefs about group or individual traits. By using Brunswik's lens model perspective in combination with concepts from signal detection theory, judgments of stereotypes can be discovered to be accurate or inaccurate depending on how perceivers judge or use the cues. In drawing on research traditions and theoretical frameworks from both social and personality psychology, researchers can go beyond an all‐or‐nothing stance regarding stereotype accuracy to achieve a more nuanced understanding of when, how, and to what extent stereotypes are accurate. 相似文献

Forensic examiners routinely compare a crime-relevant mark of unknown origin against a single suspect's sample, which may create an expectation that the two will match. We tested how embedding the suspect's sample among known-innocent fillers (i.e., an evidence lineup) affects expert decision-making. Experienced fingerprint examiners (N = 43) compared crime-relevant marks against either individual suspect fingerprints (i.e., the standard procedure) or arrays of fingerprints (i.e., evidence lineups), with a matching fingerprint either present or absent. Evidence lineups promoted conservative decision-making, as evidenced by fewer correct IDs and a higher rate of inconclusive judgments. Though errors were rare, evidence lineups also occasionally revealed errors that would have otherwise gone undetected. Our findings thus support arguments that evidence lineups can expose fraud, identify flawed methodologies, and curb overconfidence. The potential benefits and challenges of implementing evidence lineups in forensic laboratories are discussed. 相似文献

Rats were given exposure either to an odor (almond) or a compound of odor plus taste (almond plus saline), prior to training in which the odor served as the conditioned stimulus. It was found, for both appetitive and aversive procedures, that conditioning was retarded by preexposure (a latent inhibition effect), and the extent of the retardation was greater in rats preexposed to the compound (i.e., latent inhibition to the odor was potentiated by the presence of the taste). In contrast, the presence of the taste during conditioning itself overshadowed learning about the odor. We argue that the presence of the salient taste in compound with the odor enhances the rate of associative learning, producing a rapid loss in the associability of the odor. This loss of associability will generate both overshadowing and the potentiation of latent inhibition that is observed after preexposure to the compound. 相似文献

The effects of brief daily separation, also known as "handling," during the first 2 weeks of life on play behavior and fearfulness toward a predatory odor were assessed in juvenile rats. Handled rats were more playful than nonhandled control rats, and while handling had no effect on the direct response of these rats toward a predatory odor, handled rats did not exhibit a conditioned suppression of play when tested later in the same context where they had been exposed to the predatory odor. Handled rats were still wary of the environment in that they continued to show a heightened level of risk assessment behavior. These data suggest that early postnatal experiences may play a significant role in determining how an animal deals with predatory threats later in life. 相似文献

The following was meant to be a ‘fun paper’, which the author's honesty and natural seriousness of mind prevented from coming off well. Its main theme is that it is not wrong to eat meat provided the animals eaten are painlessly killed or – usually in the case of human animals – already dead. In the course of his remarks the author touches on: the bearing of affluence on vegetarianism; animal rights; child eating; treating animals as ends and with due Kantian respect; the inadequacy of the word ‘duty’; aesthetics and morals; the distinction between private behaviour – say driving on the left hand side of the road – and public duty – say advocating or legislating for driving on the right hand side of the road; our duties to vegetables, snakes, flying ants and Martians; and the desirability of irrationality in matters of duty; stealing and eating as much meat as possible as a way of bringing the meat industry to its knees; the contribution that animals should make to animal welfare, viz. allowing themselves to be eaten. He ends by emphasising the likeness of non‐human animals to human animals. 1 相似文献

Ethnic groups differ in rates of suicidal behaviors among youths, the context within which suicidal behavior occurs (e.g., different precipitants, vulnerability and protective factors, and reactions to suicidal behaviors), and patterns of help-seeking. In this article, the authors discuss the cultural context of suicidal behavior among African American, American Indian and Alaska Native, Asian American and Pacific Islander, and Latino adolescents, and the implications of these contexts for suicide prevention and treatment. Several cross-cutting issues are discussed, including acculturative stress and protective factors within cultures; the roles of religion and spirituality and the family in culturally sensitive interventions; different manifestations and interpretations of distress in different cultures; and the impact of stigma and cultural distrust on help-seeking. The needs for culturally sensitive and community- based interventions are discussed, along with future opportunities for research in intervention development and evaluation. 相似文献

Four studies measure participants' accuracy in remembering, without forewarning, their own nonverbal behavior after an interpersonal interaction. Self-accuracy for smiling, nodding, gazing, hand gesturing, and self-touching is scored by comparing the participants' recollections with coding based on videotape. Self-accuracy is above chance and of modest magnitude on average. Self-accuracy is greatest for smiling; intermediate for nodding, gazing, and gesturing; and lowest for self-touching. It is higher when participants focus attention away from the self (learning as much as possible about the partner, rearranging the furniture in the room, evaluating the partner, smiling and gazing at the partner) than when participants are more self-focused (getting acquainted, trying to make a good impression on the partner, being evaluated by the partner, engaging in more self-touching). The contributions of cognitive demand and affective state are discussed. 相似文献
