The visual system is remarkably efficient at extracting regularities from the environment through statistical learning. While such extraction has extensive consequences on cognition, it is unclear how statistical learning shapes the representations of the individual objects that comprise the regularities. Here we examine how statistical learning alters object representations. In three experiments, participants were exposed to either random arrays containing objects in a random order, or structured arrays containing object pairs where two objects appeared next to each other in fixed spatial or temporal configurations. After exposure, one object in each pair was briefly presented and participants judged the location or the orientation of the object without seeing the other object in the pair. We found that when an object reliably appeared next to another object in space, it was judged as being closer to the other object in space even though the other object was never presented (Experiments 1 and 2). Likewise, when an object reliably preceded another object in time, its orientation was biased toward the orientation of the other object even though the other object was never presented (Experiment 3). These results demonstrated that statistical learning fundamentally shapes how individual objects are represented in visual memory, by biasing the representation of one object toward its co-occurring partner. Importantly, participants in all experiments were not explicitly aware of the regularities. Thus, the bias in object representations was implicit. The current study reveals a novel impact of statistical learning on object representation: spatially co-occurring objects are represented as being closer in space, and temporally co-occurring objects are represented as having more similar features. 相似文献

Recent research has revealed that a simple action (pressing a computer key) produced in response to a visual object prioritizes features of that object in subsequent visual search. The effects of simple action, however, have only been studied with search displays that required serial search. Here we explored whether simple actions have an effect when the target in visual search is always a salient singleton. Participants viewed a coloured shape at the beginning of each trial, and sometimes they acted (pressed the space bar) in response to it. In the subsequent search task, after acting (but not after viewing), the previously-seen colour affected search performance even though the target was always a salient singleton and the colour was uninformative. The results reveal that prior action can interact with bottom-up salience during search. Implications for our understanding of both visual search and repetition priming are discussed. 相似文献

Research on eye witness memory in older children and adults revealed that verbally describing unfamiliar faces impairs later recognition of these faces, known as the “verbal overshadowing effect”. The aim of this study was to investigate whether a verbal overshadowing effect occurs in 4- to 6-year olds, too, and whether visualization (i.e., drawing the seen face) might elicit a visual overshadowing effect. Instead of a verbal overshadowing effect, a verbal facilitation effect was revealed with verbal intelligence being a significant predictor for recognition accuracy in the verbalization group but not in the control group. No effect of visualization was observed on recognition accuracy. Potential explanations for the results are discussed. 相似文献

AbstractIn thinking and talking about wellbeing, people often deploy spatial metaphors, such as identifying positive and negative affect with ‘up’ and ‘down’ respectively. However, there has not yet been a systematic investigation of how wellbeing is represented through metaphor. To shed light on this topic, a content analysis was conducted of spatial metaphors in academic discourse on wellbeing, focusing on recent editions of two leading journals, the Journal of Positive Psychology, and the British Journal of Clinical Psychology. Across 28 papers, 54 spatial metaphors were identified, grouped into four main categories: verticality; horizontality; configuration; and dynamism. Above all, wellbeing is associated with interior expansiveness, with positive valence usually attaching to vertical metaphors of height and depth, horizontal metaphors of width and breadth, and configuration metaphors of size and growth. The analysis thus offers valuable insights into the subjective dynamics of wellbeing. 相似文献

ABSTRACTThere is a recent scholarly trend drawing similarities between Aristotle’s conceptions of ethics and demonstrative science. One such similarity has become widely and rightly recognized: for Aristotle both ethics and demonstrative science seek essential definitions of phenomena. The task of the paper is to show that German philosopher and classicist Hans-Georg Gadamer not only prefigured this interpretative trend, he also identified a problematic feature of Aristotle’s method so construed. The problematic feature is semantic. For Aristotle essential definitions must consist of univocal terms, but such univocity cannot be maintained if the definienda and definientes are concepts to be usefully employed in everyday ethical judgements. Gadamer therefore points out a problematic tension in Aristotle’s ethics. On the one hand, ethical inquiry should have practical application, but, on the other hand, the semantic assumptions underlying inquiry imply that it cannot. 相似文献

Drawing on the six stages identified by Henton and Midgley (2012) in the narratives of five child psychotherapists involved in the IMPACT study on their evolving attitudes towards participation in outcome research, this paper explores another child psychotherapist’s internal and external world experiences of writing a National Institute of Health Research grant application for a randomised controlled trial feasibility study. It makes use of the key associations that came to mind on first reading Henton and Midgley’s article, outlines the practical and emotional stages of developing the grant proposal and briefly considers some of the wider implications of this kind of work on a personal, organisational and professional level. 相似文献

To visualize the accumulation of good and bad karma in terms of credit or debt in a bank account is a common feature in works on Buddhism and other Indian traditions. Applying conceptual metaphor theory, this article tracks the metaphorical framework of understanding karma as a kind of ‘heavenly bank account’ back to its roots in early European scholarship. Based on a comparison with metaphors for karma to be found in Pāli texts of the Theravāda tradition, namely, the analogies of ripening, inheritance, and the dark/bright dichotomy, this article argues that the ‘bank-account’ imagery differs in significant – if subtle – respects from these emic metaphors, displaying certain Judeo-Christian preconceptions of moral bookkeeping, sin, and salvation. 相似文献

Objective: The present study investigates the effects of graphic cigarette warnings compared to text-only cigarette warnings on smokers’ explicit (i.e. ratings of the packages, cognitions about smoking, perceived health risk, quit intentions) and implicit attitudes. In addition, participants’ visual attention towards the graphic warnings was recorded using eye-tracking methodology.Design and methods: Sixty-three smokers participated in the present study and either viewed graphic cigarette warnings with aversive and non-aversive images or text-only warnings. Data were analysed using analysis of variance and correlation analysis.Results: Especially, graphic cigarette warnings with aversive content drew attention and elicited high threat. However, whereas attention directed to the textual information of the graphic warnings predicted smokers’ risk perceptions, attention directed to the images of the graphic warnings did not. Moreover, smokers’ in the graphic warning condition reported more positive cognitions about smoking, thus revealing cognitive dissonance.Conclusion: Smokers employ defensive psychological mechanisms when confronted with threatening warnings. Although aversive images attract attention, they do not promote health knowledge. Implications for graphic health warnings and the importance of taking their content (i.e. aversive vs. non-aversive images) into account are discussed. 相似文献

Studies on adults have revealed a disadvantageous effect of negative emotional stimuli on executive functions (EF), and it is suggested that this effect is amplified in children. The present study’s aim was to assess how emotional facial expressions affected working memory in 9- to 12-year-olds, using a working memory task with emotional facial expressions as stimuli. Additionally, we explored how degree of internalizing and externalizing symptoms in typically developing children was related to performance on the same task. Before employing the working memory task with emotional facial expressions as stimuli, an independent sample of 9- to 12-year-olds was asked to recognize the facial expressions intended to serve as stimuli for the working memory task and to rate the facial expressions on the degree to which the emotion was expressed and for arousal to obtain a baseline for how children during this age recognize and react to facial expressions. The first study revealed that children rated the facial expressions with similar intensity and arousal across age. When employing the working memory task with facial expressions, results revealed that negatively valenced expressions impaired working memory more than neutral and positively valenced expressions. The ability to successfully complete the working memory task increased between 9 to 12 years of age. Children’s total problems were associated with poorer performance on the working memory task with facial expressions. Results on the effect of emotion on working memory are discussed in light of recent models and empirical findings on how emotional information might interact and interfere with cognitive processes such as working memory. 相似文献

Although studies have examined the effects of interventions focused on preterm infants, few studies have examined the effects on maternal distress (anxiety, depressive symptoms, post-traumatic stress symptoms, parenting stress) or parenting. This study examined the effects of the auditory–tactile–visual–vestibular (ATVV) intervention and kangaroo care (KC) on maternal distress and the mother–infant relationship compared to an attention control group.240 mothers from four hospitals were randomly assigned to the three groups. Maternal characteristics in the three groups were similar: 64.1% of ATVV mothers, 64.2% of KC mothers, and 76.5% of control mothers were African American; maternal age averaged 26.3 years for ATVV mothers, 28.1 for KC mothers, and 26.6 for control mothers; and years of education averaged 13.6 for ATVV and KC mothers, and 13.1 for control mothers. Mothers only differed on parity: 68.4% of ATVV and 54.7% of KC mothers were first-time mothers as compared to 43.6% of control mothers. Their infants had a similar mean gestational ages (27.0 weeks for ATVV, 27.2 for KC, and 27.4 for control) and mean birthweights (993 g for ATVV, 1022 for KC, and 1023 for control).Mothers completed questionnaires during hospitalization, and at 2, 6 and 12 months corrected age on demographic characteristics, depressive symptoms, state anxiety, post-traumatic stress symptoms, parenting stress, worry about child health, and child vulnerability (only at 12 months). At 2 and 6 months, 45-min videotapes of mother–infant interactions were made, and the HOME Inventory was scored. Behaviors coded from the videotapes and a HOME subscale were combined into five interactive dimensions: maternal positive involvement and developmental stimulation and child social behaviors, developmental maturity, and irritability.Intervention effects were examined using general linear mixed models controlling for parity and recruitment site. The groups did not differ on any maternal distress variable. Kangaroo care mothers showed a more rapid decline in worry than the other mothers. The only interactive dimensions that differed between the groups were child social behaviors and developmental maturity, which were both higher for kangaroo care infants. Change over time in several individual infant behaviors was affected by the interventions. When mothers reported on the interventions they performed, regardless of group assignment, massage (any form including ATVV) was associated with a more rapid decline in depressive symptoms and higher HOME scores. Performing either intervention was associated with lower parenting stress. These findings suggest that as short-term interventions, KC and ATVV have important effects on mothers and their preterm infants, especially in the first half of the first year. 相似文献
