The author's purpose was to examine children's recognition of emotional facial expressions, by comparing two types of stimulus: photographs and drawings. The author aimed to investigate whether drawings could be considered as a more evocative material than photographs, as a function of age and emotion. Five- and 7-year-old children were presented with photographs and drawings displaying facial expressions of 4 basic emotions (i.e., happiness, sadness, anger, and fear) and were asked to perform a matching task by pointing to the face corresponding to the target emotion labeled by the experimenter. The photographs we used were selected from the Radboud Faces Database and the drawings were designed on the basis of both the facial components involved in the expression of these emotions and the graphic cues children tend to use when asked to depict these emotions in their own drawings. Our results show that drawings are better recognized than photographs, for sadness, anger, and fear (with no difference for happiness, due to a ceiling effect). And that the difference between the 2 types of stimuli tends to be more important for 5-year-olds compared to 7-year-olds. These results are discussed in view of their implications, both for future research and for practical application.  相似文献

The theory of direct learning (D. M. Jacobs &; C. F. Michaels, 2007 Jacobs, D. M., &; Michaels, C. F. (2007). Direct learning. Ecological Psychology, 19, 321349.[Taylor &; Francis Online], [Web of Science ®] [Google Scholar]) has proven useful in understanding improvement in perception and exploratory action. Here the authors assess its usefulness for understanding the learning of a motor skill, bimanual tapping at a difficult phase relation. Twenty participants attempted to learn to tap with 2 index fingers at 2 Hz with a phase lag of 90° (i.e., with a right-right period of 500 ms and a right-left period of 125 ms). There were 30 trials, each with 50 tapping cycles. Computer-screen feedback informed of errors in both period and phase for each pair of taps. Participants differed dramatically in their success. Learning was assessed by identifying the succession of attractors capturing tapping over the experiment. A few participants’ attractors migrated from antiphase to 90° with an appropriate period; others became attracted to a fixed right-left interval, rather than phase, with or without attraction to period. Changes in attractor loci were explained with mixed success by direct learning, inviting elaboration of the theory. The transition to interval attractors was understood as a change in intention, and was remarkable for its indifference to typical bimanual interactions.  相似文献

The current longitudinal study examined whether the personality vulnerabilities of self-criticism and dependency prospectively predicted stress generation in Chinese adolescents. Participants included 1,116 adolescents (588 girls and 528 boys), aged 15 to 18 years from rural, urban and ultra-urban mainland China. Participants completed self-report measures of personality, depressive and anxious symptoms and participated in a clinical interview assessing lifetime history of depression. The occurrence of negative life events was measured using a contextual-threat interview every 6-months for a total period of 18-months. Logistic regression analyses showed that after controlling for past depressive episodes and current depressive and anxious symptoms, self-criticism was prospectively associated with the occurrence of interpersonal stress generation, but not noninterpersonal stress generation. Dependency also predicted interpersonal stress generation, although only in girls and not boys. In line with previous Western findings, girls reported more interpersonal stress generation. Analyses across 3 levels of urbanization revealed several significant differences including higher reported interpersonal stress generation in urban girls than urban boys and overall higher levels of negative life events in ultra-urban youth. In sum, findings from the current study suggest that the stress generation process may be generalizable to Chinese youth.  相似文献

Interventions based on functional analyses may result in better treatment outcomes than those using arbitrary reinforcers. However, functional analyses may be impractical in some situations, or an immediate intervention may be necessary while a functional analysis is being conducted. In these situations, delivering the social reinforcers most commonly identified by functional analyses (attention, access to tangibles, and escape from demands) following appropriate behavior and withholding these events following problem behavior may improve behavior. We assessed the extent to which this type of intervention would improve child behavior with three participants. All participants engaged in moderate to high rates of problem behavior and very little appropriate requesting during baseline, and high rates of appropriate requests and reduced rates of problem behavior during treatment.  相似文献

Abstract: Hilary Putnam's philosophical views have undergone extensive interpretation over many years. One such interpretive work is George Myerson's book Rhetoric, Reason and Society. Myerson's interest in dialogic rationalism leads him to examine the views of many theorists of rationality, philosophers and nonphilosophers alike. As a prominent philosopher of rationality, Putnam is at the very center of this examination. Notwithstanding this fact, I contend that Myerson misinterprets the dialectical character of Putnam's philosophy in general and of Putnam's views on rationality in particular. This misinterpretation, I argue, is revealing of an illusion of thought to which Myerson is subject, an illusion that makes it seem that it is possible to theorize intelligibly about rationality from a metaphysical standpoint. This same illusion, I claim, also makes it seem that Myerson's positive views on rationality are intelligible. Employing a close textual analysis of Myerson's book, I argue that neither scenario is the case.  相似文献

Most research into peer victimisation has focussed on children aged 8 years and above and has included a study of the correlates of victimisation, including cognitive and social skills, and attachment profiles. Recent research has started to investigate aggression and victimisation in younger groups and has found that the nature of aggression differs from that in older children in terms of the types of victimisation involved and the stability of the roles. This study investigated some of the correlates of roles taken in victimisation in 104 children aged 4–6 years, using a cartoon methodology to elicit peer nominations for aggressor, victim, and defender. It examined the social cognitive abilities, executive function skills, and attachment profiles of aggressors, victims, and defenders. Victims did not exhibit poor performance on the social cognitive tasks or have insecure attachment qualities as has been found with victims during middle childhood. Aggressors did not perform highly on the social cognitive tasks in contrast to older aggressors and bullies. Defenders were found to perform above average (although not significantly different from other groups) on the social cognitive tasks. These findings are related to the nature of aggression and victimisation at this age, and a developmental change hypothesis is proposed to accommodate them. Aggr.

Evidence suggests that anxiety is associated with a shift of visual attention toward threatening stimuli in the environment, such as facial expressions (Mogg & Bradley, 1999). More recent evidence, however, indicates that anxiety may be better characterized by a failure to rapidly disengage the visual attention system away from threat-related facial expressions (Fox, Russo, Bowles, & Dutton, 2001). The present study further investigates this delayed disengagement hypothesis. Results show that high trait-anxious individuals, in contrast to low trait-anxious individuals, take longer to classify peripheral target letters when fearful facial expressions were presented at fixation relative to sad, happy, or neutral expressions. These findings demonstrate a specific tendency to dwell on fear-relevant stimuli, as opposed to negative information in general. These findings are considered from an evolutionary perspective and the possible role of delayed disengagement from threat in the maintenance of anxiety states is also discussed.  相似文献

This study examined relations between the incidence of workplace bullying and the everyday experiences of members of ethnic and racial minorities in the American workplace. Particular attention was paid to expressions of bullying that overtly or specifically refer to race or ethnicity, in the form of more or less subtle acts of discrimination and hostile treatment, introducing the term `racial/ethnic bullying.' Participants belonging to four racial/ethnic groups (Asians, African-Americans, Hispanics/Latinos, and whites) responded to a written survey of general and racial/ethnic bullying experiences, responses, and preferred modes and methods of internal organizational redress and dispute resolution. Very different profiles emerged between bullying perpetrated by supervisors/superiors versus co-workers/peers in the organization.  相似文献

Name learning strategies including retrieval practice, semantic associations and imagery were compared in laboratory‐based and real‐life experiments. Experiments 1 and 2 studied expanding retrieval practice and a semantic association strategy as memory improvement techniques for learning proper names. Participants either retrieved or restudied names on the same, expanding schedule. After a short, filled interval, cued recall of names was about 250% better following retrieval than restudy and 200% better with than without semantic associations. Together, the techniques improved recall by 300–400%. In Experiment 3, retrieval practice was compared with an imagery mnemonic for name learning under real‐life social conditions: Participants sought to learn the names of people they met at a party. Retrieval practice produced 50% higher recall after 24–72 hours but the imagery mnemonic was no more effective than non‐directed instructions to learn names.
