Television can be a powerful education tool; however, content makers must understand the factors that engage attention and promote learning from screen media. Prior research has suggested that social engagement is critical for learning and that interactivity may enhance the educational quality of children’s media. The present study examined the effects of increasing the social interactivity of television on children’s visual attention and word learning. Three- to 5-year-old (Mage = 4;5, SD = 9 months) children completed a task in which they viewed videos of an actress teaching them the Swahili label for an on-screen image. Each child viewed these video clips in 4 conditions that parametrically manipulated social engagement and interactivity. We then tested whether each child had successfully learned the Swahili labels. Though 5-year-old children were able to learn words in all conditions, we found that there was an optimal level of social engagement that best supported learning for all participants, defined by engaging the child but not distracting from word labeling. Our eye-tracking data indicated that children in this condition spent more time looking at the target image and less time looking at the actress’s face as compared with the most interactive condition. These findings suggest that social interactivity is critical to engaging attention and promoting learning from screen media up until a certain point, after which social stimuli may draw attention away from target images and impair children’s word learning.  相似文献

Property evaluations rarely occur in the absence of social context. However, no research has investigated how intergroup processes related to prejudice extend to concepts of property. In the present research, we propose that factors such as group status, prejudice and pressure to mask prejudiced attitudes affect how people value the property of racial ingroup and outgroup members. In Study 1, White American and Asian American participants were asked to appraise a hand‐painted mug that was ostensibly created by either a White or an Asian person. Asian participants demonstrated an ingroup bias. White participants showed an outgroup bias, but this effect was qualified. Specifically, among White participants, higher racism towards Asian Americans predicted higher valuations of mugs created by Asian people. Study 2 revealed that White Americans' prejudice towards Asian Americans predicted higher valuations of the mug created by an Asian person only when participants were highly concerned about conveying a non‐prejudiced personal image. Our results suggest that, ironically, prejudiced majority group members evaluate the property of minority group members whom they dislike more favourably. The current findings provide a foundation for melding intergroup relations research with research on property and ownership.  相似文献

What is the nature and function of relief? Relief has been studied little in psychological science despite its familiarity and pervasiveness. Two studies revealed that relief can result from two distinct situations: the narrow avoidance of an aversive outcome (near-miss relief) and completion of an onerous or aversive event (task-completion relief). Study 1 found that recollections of near-miss relief were marked by more downward counterfactual thoughts and greater feelings of social isolation than recollections of task-completion relief. Study 2 experimentally elicited the two types of relief and found mediational evidence that relief following near misses elicits feelings of social isolation via its stimulation of counterfactual thinking. That near-miss relief is characterized by counterfactual thinking suggests that it prompts people to contemplate how to avert similar experiences in the future, whereas task-completion relief may serve to reinforce endurance during difficult tasks.  相似文献

Emotion regulation can be achieved in various ways, but few studies have evaluated the extent to which the neurocognitive substrates of these distinct operations overlap. In the study reported here, functional magnetic resonance imaging (fMRI) was used to measure activity in the amygdala and prefrontal cortex of 10 participants who completed two independent tasks of emotion regulation-reappraisal, measuring intentional emotion regulation, and affect labeling, measuring incidental emotion regulation-with the objective of identifying potential overlap in the neural substrates underlying each task. Analyses focused on a priori regions of interest in the amygdala and inferior frontal gyrus (IFG). For both tasks, fMRI showed decreased amygdala activation during emotion regulation compared with emotion conditions. During reappraisal, this decrease in amygdala activation was accompanied by a proportional decrease in emotional intensity ratings; during affect labeling, the decrease in amygdala activation correlated with self-reported aggression. Importantly, across participants, the magnitude of decrease in amygdala activation during reappraisal correlated with the magnitude of decrease during affect labeling, even though the tasks were administered on separate days, and values indexing amygdala activation during each task were extracted independently of one another. In addition, IFG-amygdala connectivity, assessed via psychophysiological interaction analysis, overlapped between tasks in two regions within the right IFG. The results suggest that the two tasks recruit overlapping regions of prefrontal cortex, resulting in similar reductions in amygdala activation, regardless of the strategy employed. Intentional and incidental forms of emotion regulation, despite their phenomenological differences, may therefore converge on a common neurocognitive pathway.  相似文献

The current study evaluated the degree to which startle reflexes (SRs) in safe conditions versus danger conditions were predictive of the onset of anxiety disorders. Specificity of these effects to anxiety disorders was evaluated in comparison to unipolar depressive disorders and with consideration of level of neuroticism. A startle paradigm was administered at baseline to 132 nondisordered adolescents as part of a longitudinal study examining risk factors for emotional disorders. Participants underwent a repetition of eight safe-danger sequences and were told that delivery of an aversive stimulus leading to a muscle contraction of the arm would occur only in the late part of danger conditions. One aversive stimulus occurred midway in the safe-danger sequences. Participants were assessed for the onset of anxiety and unipolar depressive disorders annually over the next 3 to 4 years. Larger SR magnitude during safe conditions following delivery of the aversive stimulus predicted the subsequent first onset of anxiety disorders. Moreover, prediction of the onset of anxiety disorders remained significant above and beyond the effects of comorbid unipolar depression, neuroticism, and subjective ratings of intensity of the aversive stimulus. In sum, elevated responding to safe conditions following an aversive stimulus appears to be a specific, prospective risk factor for the first onset of anxiety disorders.  相似文献

The current diagnostic nomenclature for eating disorders has shortcomings. Empirical attempts to identify a new nomenclature have found numerous latent structures, but validation of this work has been largely cross-sectional, and nothing is known yet about the relationship of derived latent classes to mortality. This study examined latent diagnostic structure in 1,885 participants seeking outpatient eating disorder treatment over an 18-year period. Eating disorder symptoms were used as indicators, and the main validator was mortality as assessed using computerized linkage to the National Death Index. Six latent classes were derived; three of the six had significantly elevated standardized mortality ratios. It appeared that the latent class structure yielded better delineation of mortality risk than the existing classifications in the Diagnostic and Statistical Manual of Mental Disorders. These results provide support for an alternative, empirically derived diagnostic structure.  相似文献

The Diagnostic and Statistical Manual for Mental Disorders, Fifth Edition (DSM-5) workgroup for disruptive behavior disorders is considering adopting a frequency threshold for symptoms of oppositional defiant disorder (ODD). In the present study, the impact of substituting the term "often" with a specific age-based frequency on impairment and prognosis among preschool children was tested in a longitudinal design. Mutually exclusive groups were created to identify children who met criteria for ODD based on a symptom threshold of "often," as in Diagnostic and Statistical Manual for Mental Disorders, Fourth Edition (DSM-4), and those that met criteria for ODD based on a threshold of "1-2 times per day," which approximated the proposal for DSM-5. Comparisons of these groups to each other and to nondiagnosed peers determined the impact of changing the symptom threshold on impairment and prognosis. Close to one-third of children who met DSM-4 criteria for ODD did not meet criteria under the alternative diagnosis; African American children were overrepresented in this group. Preschoolers who met DSM-4, but not the alternative criteria, had higher rates of ODD, conduct disorder (CD), and were more impaired than their nondiagnosed peers at baseline and follow-up. Preschoolers meeting DSM-4 criteria were less impaired than children meeting the alternative ODD criteria at baseline according to parent, but not according to teacher report. No differences could be detected between those meeting DSM-4 and those meeting the alternative criteria in rate of ODD, CD, or impairment at follow-up. Among clinically referred preschool children, changing the symptom threshold for ODD could result in a sizable group of children who would no longer meet diagnostic criteria, despite demonstrating significant morbidity concurrently and prospectively.  相似文献

A total of 69 preschool children were tested on measures of false belief understanding (the Unexpected Transfer task), inhibitory control (the Grass/Snow task), and strategic reasoning (the Windows task). For each task, children indicated their response either by pointing with their index finger or by using a nonstandard response mode (pointing with a rotating arrow). The means of responding had no effect on children's performance on the Grass/Snow task or on the Unexpected Transfer task, although children performed better on the Unexpected Transfer task when the key object in the story was removed. In contrast, performance on the Windows task was significantly better when children pointed with the rotating arrow. A follow-up experiment with 79 preschoolers found that this improved performance on the Windows task was sustained even after the nonstandard response mode was removed and children again pointed with their finger. These findings together suggest that nonstandard response modes do not help children to inhibit prepotent pointing responses but may help them to formulate response strategies on reasoning tasks by discouraging unreflective impulsive responding.  相似文献
