In line with ideomotor theory, numerous response–effect compatibility (REC) studies have revealed evidence that action effects are anticipated prior to action initiation, as indicated by an REC effect: For example, a response is given faster when its effect occurs on the same rather than on the opposite side. So far, REC studies have only investigated immediate effects—that is, effects occurring immediately after the response is given. However, it may be argued that in everyday life many actions cause effects that do not occur immediately. Additionally, because actions can have more than one effect, desired effects occurring in the future may only be arrived at if fundamental effects are achieved first. In the present study, we investigated whether temporally more distal effects are anticipated in order to initiate actions, and how multiple, serially occurring effects are represented. To this end, a spatial REC paradigm was extended in such a way that a first, immediate effect (i.e., immediately following the response; E1) was followed 500 ms later by another visual effect (E2). An REC effect was only observed for the temporally more distal E2, and this result suggests that temporally more distal effects can also be anticipated during action selection. 相似文献

Deletion of the GluA1 AMPA receptor subunit impairs short-term spatial recognition memory. It has been suggested that short-term recognition depends upon memory caused by the recent presentation of a stimulus that is independent of contextual-retrieval processes. The aim of the present set of experiments was to test whether the role of GluA1 extends to nonspatial recognition memory. Wild-type and GluA1 knockout mice were tested on the standard object recognition task and a context-independent recognition task that required recency-dependent memory. In a first set of experiments it was found that GluA1 deletion failed to impair performance on either of the object recognition or recency-dependent tasks. However, GluA1 knockout mice displayed increased levels of exploration of the objects in both the sample and test phases compared to controls. In contrast, when the time that GluA1 knockout mice spent exploring the objects was yoked to control mice during the sample phase, it was found that GluA1 deletion now impaired performance on both the object recognition and the recency-dependent tasks. GluA1 deletion failed to impair performance on a context-dependent recognition task regardless of whether object exposure in knockout mice was yoked to controls or not. These results demonstrate that GluA1 is necessary for nonspatial as well as spatial recognition memory and plays an important role in recency-dependent memory processes. 相似文献

Previous studies have shown that spatial attention prolongs the perceived duration of visual stimuli. Chen and O'Neill (Perception & Psychophysics, 63, 1229-1238, 2001) reported, however, the reversed result and thus challenged the generality of this attention effect. We therefore reinvestigated the influence of spatial attention on the perceived duration of visual stimuli in various experimental settings. In five experiments, perceived duration was longer for validly cued stimuli; thus, spatial attention was found to prolong perceived duration. In a further experiment, the specific conditions were such that neither the attention effect nor the reversed pattern, as found by Chen and O'Neill, emerged. Although we cannot provide a conclusive account of why Chen and O'Neill observed the reversed attention effect, the present results reinforce the generality of the spatial attention effect on perceived duration but also make advisable a systematic examination of the factors that might modulate this effect. 相似文献

This study reports the development of the Reactive–Proactive Aggression Questionnaire (RPQ), and the differential correlates of these two forms of aggression. Antisocial, psychosocial and personality measures were obtained at ages 7 and 16 years in schoolboys, while the RPQ was administered to 334 of the boys at age 16 years. Confirmatory factor analysis indicated a significant fit for a two‐factor proactive–reactive model that replicated from one independent subsample to another. Proactive aggression was uniquely characterized at age 7 by initiation of fights, strong‐arm tactics, delinquency, poor school motivation, poor peer relationships, single‐parent status, psychosocial adversity, substance‐abusing parents, and hyperactivity, and at age 16 by a psychopathic personality, blunted affect, delinquency, and serious violent offending. Reactive aggression was uniquely characterized at age 16 by impulsivity, hostility, social anxiety, lack of close friends, unusual perceptual experiences, and ideas of reference. Findings confirm and extend the differential correlates of proactive–reactive aggression, and demonstrate that this brief but reliable and valid self‐report instrument can be used to assess proactive and reactive aggression in child and adolescent samples.

Memory has always been a central issue in psychoanalytic theory and practice. Recent developments in the cognitive and neural sciences suggest that traditional notions of memory based on stored structures which are also often underlying psychoanalytic thinking cannot account for a number of fundamental phenomena and thus need to be revised. We suggest that memory be conceived as a) a theoretical construct explaining current behaviour by reference to events that have happened in the past. b) Memory is not to be conceived as stored structures but as a function of the whole organism, as a complex, dynamic, recategorising and interactive process, which is always 'embodied'. c) Memory always has a subjective and an objective side. The subjective side is given by the individual's history, the objective side by the neural patterns generated by the sensory motor interactions with the environment. This implies that both 'narrative' (subjective) and 'historical' (objective) truth have to be taken into account achieving stable psychic change as is illustrated by extensive clinical materials taken from a psychoanalysis with a psychogenic sterile borderline patient. 相似文献

The Impact of Event Scale (ES; M. J. Horowitz, N. Wilner, & W. Alvarez, 1979) is a worldwide-used self-report measure to assess the frequency of intrusive and avoidant phenomena after a variety of traumatic experiences. The purpose of this article is to assess the psychometric value of the Dutch version of the IES (D. Brom & R. J. Kleber, 1985) in several samples of individuals who had experienced various traumatic stressors. The reliability and structure of the IES were evaluated in 3 different samples (total N = 1.588). The reliability of the Dutch version of the IES was adequate across the various stressors. The construct validity was assessed by using confirmatory factor analyses. Outcomes revealed a robust structure over the various samples, generally supporting the composition of the original IES. 相似文献

Traces left on visual selective attention by stimuli that are not consciously identified 总被引:3,自引:0,他引:3
Briefly presented information, even if unidentifiable, may speed or delay required responses to following events. It has been assumed that this priming of the motor system may occur without affecting attention to priming and following stimuli. In contrast to this notion, the present study reports that such unidentified stimuli have effects on a physiological indicator of the attentional system. A lateral posterior electroencephalogram component was evoked by laterally presented relevant shapes, reflecting shifts of attention to those shapes. This component was absent, however, when the relevant shape was preceded by a similar shape at the same location, even if this shape was completely masked by metacontrast. The attentional shift evidently became unnecessary in this situation. Thus, unidentifiable information may leave some trace for attention-controlled selection of the following event. 相似文献

The paper summarizes the first decade of the Developmental Trends Study, a prospective longitudinal study of 177 boys. Initially, they were referred to mental health clinics in Pennsylvania (Pittsburgh), and Georgia (Athens and Atlanta). Since 1987, the boys, their parents, and their teachers have been followed up almost annually. The study is unique because the cooperation rate of participants has remained very high over the years, psychiatric diagnoses were derived from structured interviews (especially disruptive behavior disorders), and many risk factors were measured over the years. The present paper summarizes key findings on the development of disruptive behavior, especially Oppositional Defiant Disorder, Conduct Disorder, and Attention Deficit-Hyperactivity Disorder. The paper also highlights results on risk factors and comorbid conditions of disruptive behaviors. 相似文献

How do participants adapt to temporal variation of preparatory foreperiods? For reaction times, specific sequential effects have been observed. Responses become slower when the foreperiod is shorter on the current than on the previous trial. If this effect is due to changes in motor activation, it should also be visible in force of responses and in EEG measures of motor preparation, the contingent negative variation (CNV) and the lateralized readiness potential (LRP). These hypotheses were tested in a two-choice reaction task, with targets occurring 500, 1500, or 2500 ms after an acoustic warning signal. The reaction time results showed the expected pattern and were accompanied by similar effects on a fronto-central CNV and the LRP. In contrast, the increase of response force with brief current foreperiods did not depend on previous foreperiods. Thus, EEG measures confirm that sequential effects on RT are at least partially due to changes in motor activation originating from previous trials. Effects found on response force may be related to general response readiness rather than activation of motor-hand areas, which may explain the absence of a sequential effect on force in the current experiment. 相似文献
