Infants are frequently exposed to music during daily activities, including free play, and while viewing infant‐directed videotapes that contain instrumental music soundtracks. In Experiment 1, an instrumental music soundtrack was played during a live or televised demonstration to examine its effects on deferred imitation by 6‐, 12‐, and 18‐month‐old infants. Transfer of information was indexed via deferred imitation of the target actions following a 24‐h delay. For half the infants, the music context was also reinstated at the time of test. Performance by experimental groups was compared to that of a baseline control group that participated in the test session without prior exposure to the demonstration. Imitation performance was above baseline for the live groups but not for the video groups regardless of age or the music context at test. In Experiment 2, we added matched sound effects to the video demonstration and infants performed above baseline. We conclude that the music track creates additional cognitive load, disrupts selective attention to the target actions and inhibits transfer of learning from television of the imitation task. Music may impair an infant's ability to translate information from a two‐dimensional to three‐dimensional world even if the auditory context remains the same.

We assessed preference for video or in vivo modeling using a concurrent-chains arrangement with 3 children with autism. The two modeling conditions produced similar acquisition rates and no differential selection (i.e., preference) for all 3 participants.  相似文献

This study investigated the effects of combined audience feedback with video feedback plus cognitive preparation, and cognitive review (enabling deeper processing of feedback) on state anxiety and self-perceptions including perception of performance and perceived probability of negative evaluation in socially anxious individuals during a speech performance. One hundred and forty socially anxious students were randomly assigned to four conditions: Cognitive Preparation + Video Feedback + Audience Feedback + Cognitive Review (CP + VF + AF + CR), Cognitive Preparation + Video Feedback + Cognitive Review (CP + VF + CR), Cognitive Preparation + Video Feedback only (CP + VF), and Control. They were asked to deliver two impromptu speeches that were evaluated by confederates. Participants’ levels of anxiety and self-perceptions pertaining to the speech task were assessed before and after feedback, and after the second speech. Compared to participants in the other conditions, participants in the CP + VF + AF + CR condition reported a significant decrease in their state anxiety and perceived probability of negative evaluation scores, and a significant increase in their positive perception of speech performance from before to after the feedback. These effects generalized to the second speech. Our results suggest that adding audience feedback to video feedback plus cognitive preparation and cognitive review may improve the effects of existing video feedback procedures in reducing anxiety symptoms and distorted self-representations in socially anxious individuals.  相似文献

电子游戏颇受儿童青睐,其用户日趋低龄化,它对幼儿的影响不容小觑。本实验以双人合作/竞技游戏为载体,考查了短时接触电子游戏对60名4~6岁幼儿的同伴交往与亲社会行为的影响,结果发现:1)幼儿与非好友玩伴共同接触双人电子游戏后会变得更喜欢自己的搭档,将其视为新好友并更希望未来与其交往;2)合作比竞技游戏更能促使幼儿喜爱玩伴,竞技游戏的获胜者比失败者更喜欢其搭档;3)年长比年少幼儿更喜欢与同伴交往;4)与其他非好友同伴相比,幼儿更愿意帮助自己的搭档。这表明短时接触内容适宜的双人电子游戏对幼儿的同伴交往和亲社会行为发展较为有益。  相似文献

Violent video game playing has been linked to a wide range of negative outcomes, especially in adolescents. In the present research, we focused on a potential determinant of adolescents’ willingness to play violent video games: social exclusion. We also tested whether exclusion can predict increased aggressiveness following violent video game playing. In two experiments, we predicted that exclusion could increase adolescents’ preferences for violent video games and interact with violent game playing fostering adolescents’ aggressive inclinations. In Study 1, 121 adolescents (aged 10–18 years) were randomly assigned to a manipulation of social exclusion. Then, they evaluated the violent content of nine different video games (violent, nonviolent, or prosocial) and reported their willingness to play each presented video game. The results showed that excluded participants expressed a greater willingness to play violent games than nonviolent or prosocial games. No such effect was found for included participants. In Study 2, both inclusionary status and video game contents were manipulated. After a manipulation of inclusionary status, 113 adolescents (aged 11–16 years) were randomly assigned to play either a violent or a nonviolent video game. Then, they were given an opportunity to express their aggressive inclinations toward the excluders. Results showed that excluded participants who played a violent game displayed the highest level of aggressive inclinations than participants who were assigned to the other experimental conditions. Overall, these findings suggest that exclusion increases preferences for violent games and that the combination of exclusion and violent game playing fuels aggressive inclinations.

Many children with disabilities have feeding problems including, but not limited to, food selectivity and/or food refusal. The purpose of this study was to evaluate the effectiveness of video modeling of contingencies alone and combined with direct exposure to the contingencies in the treatment of food selectivity. Treatment procedures included sequentially introducing videos in which models consumed nonpreferred foods or were exposed to differential reinforcement or differential reinforcement plus escape extinction. In addition, during feeding sessions, participants were exposed to differential reinforcement. Results indicated that video modeling of differential reinforcement plus direct exposure to differential reinforcement may be effective at increasing consumption of some nonpreferred foods, but the results were not replicated across all foods. For one participant, consumption of one food increased with video modeling alone.  相似文献

Online video games are social spaces for players from around the world. They use this space to form communities, relationships, and identities. However, gaming communities are not always welcoming, and some are even perceived as being “toxic.” A prevalent issue is online sexual harassment, which is keeping many women from participating in the gaming community. Research on the factors contributing to the problem is limited, though. The present study replicates and expands previous research, using a sample of 856 online gamers. The study supports earlier findings that found hostile sexism and social dominance orientation as predictors of sexual harassment perpetration in online video games. In addition, we expanded the previous research with additional predictors: machiavellianism, psychopathy, and gamer identification predicted higher sexual harassment perpetration. Our results have implications for the gaming community's role in curtailing sexual harassment and making itself a more inclusive community.  相似文献

Computerized interactive videotapes were used to train college students to use a 10-second partial-interval observational recording system. Students viewed videotapes and scored response occurrences on a computer keyboard. Incorrect scoring resulted in immediate computerized feedback and rescoring.  相似文献

Three groups of pigeons were trained with a modified discriminative autoshaping procedure to discriminate video images of other pigeons on the basis of movement. Birds of all groups were shown the same video images of other pigeons, which were either moving or still. The group to whom food was presented only after moving images learned the discrimination very quickly. A second group, to whom food was given only after still images, and a pseudocategory group, to whom food was presented after arbitrarily chosen stimuli, showed no evidence of discrimination during acquisition training. Extinction conditions led to clear differences in peck rates to moving and still images in the second group but not in the pseudocategory group. The result is related to the feature-positive effect. Generalization tests showed that the discrimination performance was based on visual features of the stimuli but was invariant against changes of size, perspective, brightness, and color. Furthermore, discrimination was maintained when novel images of pigeons under different viewing angles and seven other types of motion categories were presented. It is argued that the discrimination is based not on a common motion feature but on motion concepts or high-order generalization across motion categories.  相似文献
