When people recall together in a collaborative group they recall less than their potential. This phenomenon of collaborative inhibition is explained in terms of retrieval disruption. However, collaborative recall also re-exposes individuals to items recalled by others that they themselves might otherwise have forgotten. This re-exposure produces post-collaborative benefits in individual recall. The current study examined whether reduced retrieval disruption during group recall is related not only to less collaborative inhibition, but also to greater post-collaborative recall benefits. To test this we devised a paradigm to calculate the extent to which each individual experienced retrieval disruption during group recall. We also included two types of collaborative groups, one of which was expected to experience greater retrieval disruption than the other. Results suggest that the relationship between retrieval disruption and recall performance depends on the level at which retrieval disruption is measured. When retrieval disruption was assessed at the individual level, then minimising retrieval disruption was associated with higher recall (i.e., less collaborative inhibition and greater post-collaborative individual recall). However, when retrieval disruption was assessed at the group level there was no relationship with recall. Furthermore, the findings from this design suggest a role of cross-cueing in modulating group recall levels. 相似文献
Consensus studies from 4 cultures--in Belgium, the Czech Republic, Estonia, and Germany--as well as secondary analyses of self- and observer-reported Revised NEO Personality Inventory (NEO PI-R) data from 29 cultures suggest that there is a cross-culturally replicable pattern of difference between internal and external perspectives for the Big Five personality traits. People see themselves as more neurotic and open to experience compared to how they are seen by other people. External observers generally hold a higher opinion of an individual's conscientiousness than he or she does about him- or herself. As a rule, people think that they have more positive emotions and excitement seeking but much less assertiveness than it seems from the vantage point of an external observer. This cross-culturally replicable disparity between internal and external perspectives was not consistent with predictions based on the actor-observer hypothesis because the size of the disparity was unrelated to the visibility of personality traits. A relatively strong negative correlation (r = -.53) between the average self-minus-observer profile and social desirability ratings suggests that people in most studied cultures view themselves less favorably than they are perceived by others. 相似文献
Dorion Cairns correctly interprets the preconstituted stratum of Edmund Husserl’s Fifth Cartesian Meditation to be the primordial
ego and not the social world, as was thought by Alfred Schutz, who considered Husserl to be insufficiently attentive to the
social world’s hold upon us. Following Cairns’s interpretation, which involves recovering and reconstructing strata that may
never exist independently, one better understands how the transfer of sense “animate organism” involves automatic association,
or somatic apprehension. This sense-transfer extends to any animate organism, not just humans, and draws on extensive unreflected-upon
similarities despite the distinctive fact that the other’s body is never given to oneself as is one’s own. Following Cairns’s
interpretation, one can also understand the second epoché as an imaginative, reconstructive abstraction rather than as an example of failed ascesis. Consequently, Husserl appears as less intellectualized in his approach to empathy than often thought to be and more confident
in the phenomenologist’s capacity to imagine and attend selectively to experience. 相似文献
Various studies have demonstrated enhanced visual processing when information is presented across both visual hemifields rather than in a single hemifield (the bilateral advantage). For example, Alvarez and Cavanagh (2005) reported that observers were able to track twice as many moving visual stimuli when the tracked items were presented bilaterally rather than unilaterally, suggesting that independent resources enable tracking in the two visual fields. Motivated by similarities in the apparent capacity and neural substrates that mediate tracking and visual working memory (WM), the present work examined whether or not a bilateral advantage also arises during storage in visual WM. Using a recall procedure to assess working memory for orientation information, we found a reliable bilateral advantage; recall error was smaller with bilateral sample displays than with unilateral displays. To demonstrate that the bilateral advantage influenced storage per se rather than just encoding efficiency, we replicated the observed bilateral advantage using sequentially presented stimuli. Finally, to further characterize how bilateral presentations enhanced storage in working memory, we measured both the number and the resolution of the stored items and found that bilateral presentations lead to an increased probability of storage, rather than enhanced mnemonic resolution. Thus, the bilateral advantage extends beyond the initial selection and encoding of visual information to influence online maintenance in visual working memory. 相似文献
The idea that what we perceive are tropes (abstract particulars) is anything but new. In fact, it was one of the reasons why the ontology of tropes was postulated in the first place. Still, the claim that we perceive tropes is invariably and purely based on pre-philosophical intuitions or, indirectly, either as a supporting argument for the advantages of content view when compared to the relational view of experience, or as a supporting argument in favor of the irreducible subjective character of experience. In this paper, I take the content view for granted and argue in favor of what is herein referred to as the trope-content view of experience. My defense is a case of inference to the best explanation. The trope-content view can meet all reasonable desiderata on the experience and its content without assuming gaps or making the ad hoc assumption that there are different layers of content, or so shall I argue.
A number of studies have reported that ethanol exposure induces changes in different brain systems. The hippocampus is a brain region that is very vulnerable to ethanol exposition, which functionally results in impairment of learning and memory processes reported in heavy drinkers. Hippocampal nicotinic receptors are involved in learning and memory. In this study, we determined the effects of ethanol on the main hippocampal subtypes of neural nicotinic receptors (α7 and α4β2) in rats non-selected for alcohol consumption, in order to check for possible changes on these receptors that could be linked with alterations in learning acquisition. Binding assays were carried out with [3H]methyllycaconitine ([3H]MLA) to study the α7 and [3H]nicotine to study α4β2 receptors. Auto-shaping, continuous ratio and extinction procedures were used as behavioral tests. The results show that moderate chronic ethanol consumption for 10 weeks produces: (a) a decrease of both hippocampal nicotinic receptor subtypes without alterations in affinity; (b) no differences in behavioral performance between control rats and ethanol-drinking rats in auto-shaping and continuous ratio; (c) an improvement of performance of extinction paradigm. These results indicate that chronic ethanol consumption, at moderate levels, induces changes in hippocampal nicotinic receptors but does not impair acquisition and performance of new associative learning and even improves some kind of paradigms. These results may have implications in the biochemical basis of interactions between alcohol and nicotine and the effects of these drugs on behavior. 相似文献
The present paper uses an adaptational-continuum model of personality, based on Ferguson’s (2001) health psychology model integrating Eysenck personality factors and coping style, to provide a context for examining the relationship between forgiveness and mental health. Three hundred and twenty respondents completed measures of personality, coping style, forgiveness (forgiveness of self, others, likelihood, presence of positive forgiveness, absence of negative forgiveness), general health, stress, positive and negative affect and life satisfaction. Among respondents, all measures of forgiveness, bar one, load negatively on a neuroticism-coping factor. The remaining measure of forgiveness (presence of positive forgiveness) loaded on an extraversion-coping factor. The relationship of the neuroticism-coping-forgiveness factor was associated with poorer mental health, suggesting forgiveness is associated with better mental health within the context of this personality-coping factor. Significant positive relationships were found between the extraversion-coping-forgiveness factor and two measures of positive mental health outcomes (positive affect and life satisfaction) suggesting forgiveness is associated with some aspects of mental health within the context of this personality-coping factor. The present findings suggest that forgiveness, or failure to forgive, can be conceptualised within an adaptational-continuum model of personality. 相似文献
ABSTRACT— Working memory (WM) involves maintaining information in an on-line state. One emerging view is that information in WM is maintained via sensory recruitment , such that information is stored via sustained activity in the sensory areas that encode the to-be-remembered information. Using functional magnetic resonance imaging, we observed that key sensory regions such as primary visual cortex (V1) showed little evidence of sustained increases in mean activation during a WM delay period, though such amplitude increases have typically been used to determine whether a region is involved in on-line maintenance. However, a multivoxel pattern analysis of delay-period activity revealed a sustained pattern of activation in V1 that represented only the intentionally stored feature of a multifeature object. Moreover, the pattern of delay activity was qualitatively similar to that observed during the discrimination of sensory stimuli, suggesting that WM representations in V1 are reasonable "copies" of those evoked during pure sensory processing. 相似文献
Women’s cradling side preference has been related to contralateral hemispheric specialization of processing emotional signals; but not of processing baby’s facial expression. Therefore, 46 nulliparous female volunteers were characterized as left or non-left holders (HG) during a doll holding task. During a signal detection task they were then asked to detect the emotional baby faces in a series of baby portraits with neutral and emotional facial expressions, presented either to the left or the right visual field (VFP). ANOVA revealed a significant HG × VFP interaction on response bias data (p < .05). Response bias was lowest when emotional baby faces were presented in the visual field of cradling side preference, suggesting that women’s cradling side preference may have evolved to save cognitive resources during monitoring emotional baby face signals. 相似文献
