Taking control of reflexive social attention 总被引:8,自引:0,他引:8
Attention is shifted reflexively to where other people are looking. It has been argued by a number of investigators that this social attention effect reflects the obligatory bottom-up activation of domain-specific modules within the inferior temporal (IT) cortex that are specialized for processing face and gaze information. However, it is also the case that top-down factors may modulate the activation of IT cells. Here we examined behaviorally whether reflexive social orienting is purely automatic or sensitive to top-down modulation. Participants were shown an ambiguous stimulus that could be perceived either as representing EYES or a CAR. In we demonstrated between groups that an automatic shift of attention, equivalent to that triggered by a schematic FACE, occurred only when the stimulus was referred to as possessing EYES. In all participants received the EYES and CAR conditions. When the stimulus was first referred to as a CAR and then as EYES, an attentional shift was only present for the EYES condition. However, when the stimulus was first referred to as possessing EYES, and then later as a CAR, attentional shifts were observed for both conditions. These data indicate that the emergence of a reflexive social attention effect is influenced by top-down mechanisms but in an asymmetrical manner. Top-down processes appear to be effective for triggering IT involvement, that is, for perceiving a stimulus as a face, which produces the social attention effect. But top-down mechanisms are ineffective once IT involvement has been triggered. That is, once a stimulus has been seen as having eyes, it continues to be seen that way, and accordingly, the social attention effect persists. 相似文献

Research has demonstrated that left- and right-hand responses are facilitated when they are performed with the hand compatible with the orientation of a viewed object. This suggests that graspable objects automatically activate the motor representations that correspond to their orientation. It has recently been proposed that similar positive stimulus-response compatibility effects (PCE) may turn into negative compatibility effects (NCE) when a prime object is displayed very briefly. These NCEs are suggested to reflect motor inhibition mechanisms--motor activation triggered by briefly viewed objects may be treated by the motor system as unwanted, and thus it is rapidly inhibited. We examined whether the motor activation triggered by the orientation of a task-irrelevant object is similarly inhibited when the object is displayed briefly. In Experiment 1, a NCE was observed between the orientation of an object and the responding hand when the object was displayed for 30 or 70 ms. The effect turned into a PCE when the object was displayed for 370 ms. Experiment 2 confirmed that this motor inhibition effect was produced by the handle affordance of the object rather than some abstract visual properties of the object. 相似文献

The value of an individual case study depends to a large extent on the nature of the predictions which are tested. If, for example, behaviour is modified by a method which flies in the face of current theory and practice, then it is worth reporting, and if detailed predictions about day-to-day changes are confirmed, so much the better. This individual case study was designed to test the possibility that excessive drinking behaviour can be modified by prolonged exposure to drinking cues.Our approach is based on the hypothesis that addictive behaviour is analogous to discriminated operants. We are also making the assumption that drinking, in the alcoholic, is frequently reinforced through the avoidance of unpleasant consequences (e.g. an escalation in anxiety, frustration or withdrawal symptoms) and that these avoidance responses are discriminated since they are triggered only by certain cues.Avoidance learning has been investigated in humans and animals for at least 50 years but in recent years strong evidence has accumulated which suggests a particular modification procedure. First, it has now been demonstrated that, in animals, a very effective extinction procedure involves exposure to the discriminative stimulus (i.e. cue) whilst blocking the avoidance response (Baum, 1969). Second, psychologists have considered obsessive-compulsive rituals to be analogous to avoidance responses (Hodgson and Rachman, 1972). Compulsive gas-tap checking, for example, avoids both catastrophic events and also unpleasant emotional states. During the last ten years an effective method of modifying obsessive-compulsive rituals has been developed which involves exposure to significant cues followed by response prevention which is either supervised (Meyer, 1966) or self-imposed (Rachman et al., 1971; Hodgson et al., 1972). The same method has also been successful in the modification of compulsive masturbation (Hodgson and Rachman, 1975). 相似文献

Psychological momentum (PM) is a social phenomenon that has triggered the curiosity of sport psychologists since the early 1980s. From early to recent conceptualizations, PM has been considered as a complex construct, inherently related to variations in sport performance. Over the past 30 years, several models have been proposed to untangle how PM is triggered, which psychological changes are involved in PM experiences, and how PM relates to performance. While linear (causal) models have dominated past research on PM, researchers have recently found that PM can change nonlinearly, depending on the performance history of the competition. This systematic review aims to provide an overview of different PM models that have been proposed in the past to increase insights into the complexity of PM, including the transition from linear causal models to nonlinear dynamical models. Moreover, based on the current state of affairs, perspectives for future research are provided. 相似文献

Although many investigations into the onset of obsessive-compulsive disorder (OCD) suggest the occurrence of potential life events as triggering factors, such an association has not been well studied to date. The purpose of the present paper is to review the literature on OCD onset in order to determine whether OCD is triggered by recent life events, what specific events may serve as triggers, and the clinical and research implications of these factors. Overall, the available studies do not consistently support the theory that OCD is triggered by specific antecedent life events. However, there is a body of evidence to support the theory that the specific life events of pregnancy and birth of a child can trigger OCD. This apparent association has led to the investigation of certain neurohormonal factors, including changes in estrogen or oxytocin levels, that may be of etiopathogenetic significance in OCD. Confirming such associations may allow clinicians to provide more targeted preventive and therapeutic interventions. 相似文献

Despite the initial understanding of the word ‘triggered’ as relating to the clinical phenomenon of post-traumatic stress disorder (PTSD), this language has become a common part of the vernacular today, used by many people to apply to a wide variety of experiences and events. Counselling students are particularly sensitised to trauma, as well as identity politics, and are familiar with trigger warnings at college. They themselves have experienced trauma at high rates. Therefore, we were interested to understand how they might be using the word and interpreting the experience of being ‘triggered’, whether different sources of being triggered are related to emotional reactions, and whether a discourse analysis might indicate how and why the term has become useful and for what other experiences it might be serving as a stand-in. In this mixed-methods study, 79 counselling students from around the country shared their definitions and experiences of being ‘triggered’. Participants completed surveys and wrote narratives, which, via thematic qualitative analysis, were coded into five themes. The quantitative analysis focused on the relationship of feelings to themes and the relationship between anger suppression and coping with each theme. Discourse analysis explored how individuals wrote about responsibility and anger. It was discovered that those who wrote about being triggered from a past sexual assault did not discuss anger, nor the responsibility of others to protect them (as those who wrote about microaggressions did), but positioned themselves as overreactors. Results are discussed with regard to training and practice. 相似文献

Past research has provided abundant evidence that playing violent video games increases aggressive behavior. So far, these effects have been explained mainly as the result of priming existing knowledge structures. The research reported here examined the role of denying humanness to other people in accounting for the effect that playing a violent video game has on aggressive behavior. In two experiments, we found that playing violent video games increased dehumanization, which in turn evoked aggressive behavior. Thus, it appears that video-game-induced aggressive behavior is triggered when victimizers perceive the victim to be less human. 相似文献

Spirituality has mostly been studied in psychology as implied in the process of overcoming adversity, being triggered by negative experiences, and providing positive outcomes. By reversing this pathway, we investigated whether spirituality may also be triggered by self-transcendent positive emotions, which are elicited by stimuli appraised as demonstrating higher good and beauty. In two studies, elevation and/or admiration were induced using different methods. These emotions were compared to two control groups, a neutral state and a positive emotion (mirth). Self-transcendent positive emotions increased participants' spirituality (Studies 1 and 2), especially for the non-religious participants (Study 1). Two basic world assumptions, i.e., belief in life as meaningful (Study 1) and in the benevolence of others and the world (Study 2) mediated the effect of these emotions on spirituality. Spirituality should be understood not only as a coping strategy, but also as an upward spiralling pathway to and from self-transcendent positive emotions. 相似文献

This paper presents an intervention with Finnish surgeons using robotic technology for radical prostatectomy. It is based on the methodology of cross self-confrontations (Clot et al., 2000), enriched with the works of L. Norros around interpretativeness in complex technological environments (Norros et al., 2005). We view a collective intervention method as a way of enhancing productive reflection (Boud et al., 2006), and comment two sequences in which productive reflective can be traced. These two sequences display an interesting case of double stimulation: in these dialogues, fine-grained observation of the video recordings and dialogue of the surgeons are triggered and driven by the presence of positive margins, i.e., a medical information on whether all cancerous cells have been likely to be removed (or not), which is available a posteriori in the patient file. The paper uses this powerful double stimulation in the methodological framework of crossed self-confrontations to draft a learning method supporting productive reflection and interpretative orientation at work. 相似文献

Research has consistently found that goals triggered by environmental cues can influence decision making processes outside of conscious awareness. This lack of awareness led naturally to the presumption that decision makers could not report the activation level of nonconsciously primed goals. This paper shows that goal activation levels can be reported, so long as the report is made during the decision process on a continuous goal activation scale. These results indicate that default lack of awareness is less a limitation of the cognitive system and more a function of the method used to recover goals during a decision process. 相似文献

The magnitude of congruency effects, such as the flanker-compatibility effects, has been found to vary as a function of the congruency of the previous trial. Some studies have suggested that this congruency sequence effect is attributable to stimulus and/or response priming, and/or contingency learning, whereas other studies have suggested that the control process triggered by conflict modulates the congruency effect. The present study examined whether sequential modulation can occur without stimulus and response repetitions and contingency learning. Participants were asked to perform two color flanker-compatibility tasks alternately in a trial-by-trial manner, with four fingers of one hand in Experiment 1 and with the index and middle fingers of two hands in Experiment 2, to avoid stimulus and response repetitions and contingency learning. A significant congruency sequence effect was obtained between the congruencies of the two tasks in Experiment 1 but not in Experiment 2. These results provide evidence for the idea that the sequential modulation is, at least in part, an outcome of the top-down control process triggered by conflict, which is specific to response mode. 相似文献

Event-related potentials were recorded to substantiate the claim of a distinct psycholinguistic status of (a) pronouns vs. proper names and (b) ellipses vs. proper names. In two studies 41 students read sentences in which the number of intervening words between the anaphor and its antecedent was either small or large. Comparing the far with the near distance condition revealed anaphor resolution specific effects: Ellipses triggered a potential shift with a short latency (approximately 120-200 ms) and with a fronto-central scalp distribution while pronouns and proper names triggered one with a longer latency (approximately 360-440 ms) and a parietal to right-occipital distribution. The early effect resembled the left-anterior negativity which has been related to syntax processing, while the latter resembled an N400 which is assumed to reflect semantic integration processes. These findings support the idea that ellipses and pronouns/proper names are processed by distinct mechanisms being implemented in distinct cortical cell assemblies. 相似文献

A new look at sensory attenuation. Action-effect anticipation affects sensitivity, not response bias
The systematic association of an action that a person performs with its sensory effects is thought to attenuate that person's perception of the effect of the action. However, whether learned sensorimotor contingencies truly affect perception, rather than just inducing a response bias, has yet to be determined. The experiment presented in this article comprised two parts: an action-effect association phase and a test phase, during which the actions' perceptual effects were tested. During the association phase, specific actions (left-key and right-key presses) were associated with specific visual effects (tilted Gabor patches). In the test phase, participants' left-key presses and right-key presses triggered the onset of a low-contrast tilted Gabor patch in 50% of trials (no stimulus was presented on the remaining 50% of trials). Participants were required to report the presence or absence of this tilted Gabor patch. Our results showed that participants' sensitivity (d') to the Gabor patches was reduced by 10% when the patches were triggered by the action they had previously been associated with. This finding indicates that a person's action does not induce a response bias (c), but changes the perception (d') of the learned action effect. 相似文献

The responses of 70 trainees in suicide intervention to 10 Suicide Opinion Questionnaire items were evaluated for accuracy of their knowledge about suicide myths. Participants were Canadian adults (62 women, 8 men, M (age) = 35 yr.) representing a wide variety of occupations and educational backgrounds. Analysis indicated knowledge for most items was high but less accurate for items concerning the most common method of suicide and suicide risk across the lifespan. Those trained in suicide intervention were more knowledgeable on four items than those awaiting training; they more frequently knew that most suicides are not triggered by an argument with a spouse, people who are depressed are more likely to commit suicide, a person whose parent has committed suicide is at greater risk for suicide, and that shooting is the most common method of suicide in Canada. 相似文献
