In the present study, we investigate how spatial attention, driven by unisensory and multisensory cues, can bias the access of information into visuo-spatial working memory (VSWM). In a series of four experiments, we compared the effectiveness of spatially-nonpredictive visual, auditory, or audiovisual cues in capturing participants' spatial attention towards a location where to-be-remembered visual stimuli were or were not presented (cued/uncued trials, respectively). The results suggest that the effect of peripheral visual cues in biasing the access of information into VSWM depend on the size of the attentional focus, while auditory cues did not have direct effects in biasing VSWM. Finally, spatially congruent multisensory cues showed an enlarged attentional effect in VSWM as compared to unimodal visual cues, as a likely consequence of multisensory integration. This latter result sheds new light on the interplay between spatial attention and VSWM, pointing to the special role exerted by multisensory (audiovisual) cues. 相似文献

Abstract In this paper the authors describe their long experience, as psychoanalytically oriented psychotherapists, with an experimental school project with adolescent school drop-outs, a project that has been running in three deprived contexts of Naples. In the paper the structure of the psychological project supporting workers involved with these disruptive adolescents is analysed in detail along with the theoretical framework that lies behind it. The authors also give some illustrations that show the intense dynamics present in this field of work and some meaningful developments observed in the relationships and communications between adolescents and adults and in the group of peers. 相似文献

Male rats forced to swim in a cylinder adopted an immobile posture. Immobility was reduced by acetylcarnitine (5, 10, and 20 mg/kg) and by antidepressant drugs, such as desipramine and iproniazid, injected 24, 5, and, again, 1 h prior to behavioral testing. Acetylcarnitine also potentiated the anti-immobility effect of antidepressant drugs in the despair test. Chronic (10 days) treatment with acetylcarnitine mimicked the effect found after acute administration. It is possible that the action of the acetylcarnitine on the despair test is indicative of an antidepressant activity of this drug that is dependent on a change in the sensitivity of monoamine receptors in the brain. 相似文献

Why are people (de)motivated to mobilize in favor of immigrants? Addressing this question, we investigated the role of individuals' epistemic motivation (i.e., need for closure) in influencing the process of becoming motivated to participate in collective action in favor of immigrants in Italy. Specifically, the mediational role of binding moral foundations and political conservatism in explaining the relationship between need for closure and collective action in favor of immigrants was examined in three studies. It was hypothesized that a heightened need for closure would be indirectly and negatively associated with collective action in favor of immigrants, sequentially mediated first through binding moral foundations and then political conservatism. We found support for this prediction when either dispositional measure (Study 1 and Study 2) or an experimental induction (Study 3) of need for closure were used, and when both collective action intentions (Study 1 and Study 3) and behavior (Study 2) were assessed. The results suggest that need for closure constitutes a powerful motivational force that leads individuals to engage in uncertainty‐reducing evaluations and actions. We discuss these results regarding how they are related with previous work and their implications for research and practice. 相似文献

The last decade has seen great progress in the study of the nature of crossmodal links in exogenous and endogenous spatial attention (see [Spence, C., McDonald, J., & Driver, J. (2004). Exogenous spatial cuing studies of human crossmodal attention and multisensory integration. In C. Spence, & J. Driver (Eds.), Crossmodal space and crossmodal attention (pp. 277-320). Oxford, UK: Oxford University Press.], for a recent review). A growing body of research now highlights the existence of robust crossmodal links between auditory, visual, and tactile spatial attention. However, until recently, studies of exogenous and endogenous attention have proceeded relatively independently. In daily life, however, these two forms of attentional orienting continuously compete for the control of our attentional resources, and ultimately, our awareness. It is therefore critical to try and understand how exogenous and endogenous attention interact in both the unimodal context of the laboratory and the multisensory contexts that are more representative of everyday life. To date, progress in understanding the interaction between these two forms of orienting has primarily come from unimodal studies of visual attention. We therefore start by summarizing what has been learned from this large body of empirical research, before going on to review more recent studies that have started to investigate the interaction between endogenous and exogenous orienting in a multisensory setting. We also discuss the evidence suggesting that exogenous spatial orienting is not truly automatic, at least when assessed in a crossmodal context. Several possible models describing the interaction between endogenous and exogenous orienting are outlined and then evaluated in terms of the extant data. 相似文献

We assessed the influence of multisensory interactions on the exogenous orienting of spatial attention by comparing the ability
of auditory, tactile, and audiotactile exogenous cues to capture visuospatial attention under conditions of no perceptual
load versus high perceptual load. In Experiment 1, participants discriminated the elevation of visual targets preceded by
either unimodal or bimodal cues under conditions of either a high perceptual load (involving the monitoring of a rapidly presented
central stream of visual letters for occasionally presented target digits) or no perceptual load (when the central stream
was replaced by a fixation point). All of the cues captured spatial attention in the no-load condition, whereas only the bimodal
cues captured visuospatial attention in the highload condition. In Experiment 2, we ruled out the possibility that the presentation
of any changing stimulus at fixation (i.e., a passively monitored stream of letters) would eliminate exogenous orienting,
which instead appears to be a consequence of high perceptual load conditions (Experiment 1). These results demonstrate that
multisensory cues capture spatial attention more effectively than unimodal cues under conditions of concurrent perceptual
load. 相似文献

We compared the ability of auditory, visual, and audiovisual (bimodal) exogenous cues to capture visuo-spatial attention under conditions of no load versus high perceptual load. Participants had to discriminate the elevation (up vs. down) of visual targets preceded by either unimodal or bimodal cues under conditions of high perceptual load (in which they had to monitor a rapidly presented central stream of visual letters for occasionally presented target digits) or no perceptual load (in which the central stream was replaced by a fixation point). The results of 3 experiments showed that all 3 cues captured visuo-spatial attention in the no-load condition. By contrast, only the bimodal cues captured visuo-spatial attention in the high-load condition, indicating for the first time that multisensory integration can play a key role in disengaging spatial attention from a concurrent perceptually demanding stimulus. 相似文献

Retention of volunteers is a main issue for no‐profit organizations. In the present study, using a cross‐sectional design, determinants of volunteers’ intentions to continue their service were investigated in a sample of 116 volunteers at different Italian organizations (Mage = 42.32, SDage = 15.91). Guided by the conceptual model of the volunteer process, we hypothesized that organizational socialization should mediate the link between prosocial personality and intention to continue volunteering. Results confirmed our prediction. Findings provide suggestions for organizations concerned about volunteers’ dropout that focus on ameliorating the socialization process of less prosocial volunteers in order to support their intention to remain in the organization. 相似文献

Sub-Saharan samples are severely under-represented in the psychological literature. Taking an ecological approach, the current study examines key propositions derived from self-determination theory in a sample of adolescent girls in Mozambique. As a framework theory, self-determination theory consists of six sub-theories. We test the main premises of two of these theories: organismic integration theory and basic psychological need theory. In line with organismic integration theory, we assess the role of intrinsic, extrinsic, introjected and identified motivation for school attendance. We also test the possible moderating role of the ecological variable resource scarcity. The second part of the study focuses on the main premise of the basic psychological need sub-theory, which states that satisfaction of the needs for relatedness, competence and autonomy underlies intrinsic motivation, goal-directed behaviour (school attendance) and well-being (self-esteem). The study also assesses the moderation of resource scarcity in these relationships. Results provide support for both sub-theories of self-determination theory. Resource scarcity is not found to moderate the relationships between motivation and attendance or between need satisfaction and well-being, motivation and attendance. Implications for the universality claim of self-determination theory, as well as for the field of international development aid, are discussed. 相似文献
