To examine the relationship between imitation and locomotor development among peers during infancy, we observed free play in a class of infants in a day-care center over a one-year period. The analysis included 16 infants (mean age was 8.3 months (SD=2.3) at the beginning of the observation) and 5 caregivers. The longitudinal data were divided into the crawling, cruising, and walking periods, and the imitation of object manipulation that took place among the infants during each period was analyzed. With the development of locomotion, peer-to-peer imitation became frequent. Infants who had acquired the ability to walk demonstrated imitation more frequently in triadic interactions than in dyadic interactions. Imitation took place between infants, but it was often mediated by caregivers rather than directly between infants. The results suggest that the acquisition of locomotor skills is a link in a developmental cascade from motor development to infant peer interaction. However, it is reasonable to interpret the results as indicating that the development of locomotion does not directly affect infant interactions in isolation, but rather that walking increases both the sharing and manipulation of objects with caregivers and proximity to peers, and their combined effects form a cascade.  相似文献

人们往往会低估虚拟环境中空间的距离(空间压缩)。早期研究发现视听刺激的不一致会改善空间压缩,但听觉刺激在其中的作用及其影响效果需进一步研究。本研究首先探究了听觉刺激的有无对空间压缩的影响,接着操控视听刺激之间的物物距离进一步探究其对空间压缩的影响和改善。研究发现听觉刺激以两种方式影响空间压缩:听觉刺激的存在可以改善空间压缩;空间压缩与视听刺激的物物距离负相关。研究建议为了改善空间压缩,视听刺激应当同时呈现且物物距离至少为1 m。  相似文献

In response to the COVID-19 pandemic and consequential shutdown measures, many mental health professionals started providing therapy to patients exclusively via telehealth. Our research center, which specializes in studying and treating obsessive-compulsive disorder (OCD), historically has provided in-person exposure and response prevention (ERP) to adults with OCD, but shifted to telehealth during the pandemic. Unlike in other modes of talk therapy, ERP’s emphasis on therapist-supervised exposures presented unique opportunities and challenges to delivering treatment entirely via a virtual platform. This paper provides case examples to illustrate lessons we learned delivering ERP exclusively via telehealth in New York from March 2020 through June 2021 and offers recommendations for future study and practice. Though we observed a number of drawbacks to fully remote ERP, we also discovered advantages to delivering ERP this way, meriting additional research attention.  相似文献

Interruption and redirection (IR) procedures involve systematically disrupting an undesirable behavior and prompting an individual to engage in an alternative behavior. These procedures have been frequently assessed for reducing repetitive behaviors for autistic individuals. The primary purpose of this review was to assess IR interventions to determine whether outcomes vary according to intervention characteristics, dependent variable types, design quality, or publication status. A secondary purpose was to assess the extent to which generalization and maintenance outcomes were measured and whether characteristics of these conditions were related to outcomes. IR interventions were moderately successful for reducing repetitive behaviors but less effective for improving corollary variables such as appropriate vocalizations and functional engagement. Generalization and maintenance outcomes, when measured, were poor. Results indicate the need for alternative or augmentative procedures that focus on engagement in meaningful interactions and activities.  相似文献

The guidance design for unemployed people in changing career must increasingly take into account their existential concerns about career meaning. The literature about life and work meaning has highlighted the multifactorial complexity of meaning definition and determinants of meaning. This fact does not facilitate their use in counselling design. Bernaud et al. (2020) “Guidance for life and work meaning” device takes into account this problem; it offers many thinking prospects that organize meaning questioning in order to help people who loosed professional and personal markers. By analyzing an application of this device with the multiple cases method, our article examines how a meaning guidance helps unemployed people in giving a new direction of their career. The study of five cases with chronologic analysis unities shows how various meaning dimensions help people to clarify, to enrich and to transform their initial problematic during accompaniment and how they progress with different rhythms to major personal and vocational decisions.  相似文献

The study aims to develop and present the validation process of a questionnaire on emotional self-efficacy in the work context from the six steps proposed by Dussault et al. (2007). The study is based on the theories of emotional intelligence of Mayer and Salovey (1997), Petrides and Furham (2001) and the self-efficacy of Bandura (1997). Following an expert analysis and a pre-test, the Emotional Self-Efficacy at Work scale is composed of 41 items. The participants are 985 Canadian workers. The results of confirmatory factor analyzes support the seven-dimensional structure, namely the self-efficiency to perceive one's emotions and those of others at work, the self-efficiency to use emotions at work, the self-efficiency to understand one's emotions and those of others at work and finally, the self-efficiency to manage one's emotions and those of others at work. The results also indicate that the seven dimensions have satisfactory internal coherence indices. The results suggest that this questionnaire is well suited to describe emotional self-efficacy at work. The use of the questionnaire will be discussed.  相似文献

本研究考察新冠疫情期间,工作-家庭冲突是否通过职业倦怠增加中小学教师抑郁水平,以及心理弹性是否调节该中介作用。1127名中小学教师参与线上调查,完成中小学教师工作-家庭冲突问卷、中小学教师职业倦怠问卷、抑郁自评量表及中学教师心理弹性量表。结果发现:(1)大多教师疫情前后工作生活情况、工作-家庭冲突与抑郁的状况变化不大,少数教师疫情期间工作生活情况、工作-家庭冲突与抑郁状况变差或好转;(2)教师工作-家庭冲突与抑郁、职业倦怠呈正相关,三者均与心理弹性负相关;(3)控制额外变量后,职业倦怠是工作-家庭冲突与抑郁间的中介变量,在疫情期间工作生活状态更好、更差以及与疫情前后没有差别的教师中均成立;(4)对于感知疫情后情况更好的教师,心理弹性调节了工作-家庭冲突与职业倦怠的关系。对于感知疫情后情况更差的教师,心理弹性调节了职业倦怠与抑郁的关系。因此,缓解工作-家庭冲突和职业倦怠、提高心理弹性可减少中小学教师抑郁,保持心理健康。  相似文献

Visual context processing was investigated in both action video game players and nonplayers using the Ebbinghaus illusion task (N = 312, 39.4% female) in a cross-sectional study design. When presented in context, players showed markedly poorer target size discrimination accuracy compared with nonplayers in the 6-, 7-, 8-, and 9-years old age groups, but this difference was reduced in 10-years old group and diminished in adults. When presented in isolation (no-context), the two groups displayed similar performance in all age groups. Furthermore, nonplayers (linear) and players (bell curve) showed profoundly different age-related differences in context processing. These findings provide evidence that players might have enhanced perceptual bias to process visual context in the transition from early childhood to early adolescence, and the differences between the two groups start at early ages and continue with distinct developmental profiles.  相似文献

The development of the ability to anticipate—as manifested by preparatory actions and neural activation related to the expectation of an upcoming stimulus—may play a key role in the ontogeny of cognitive skills more broadly. This preregistered study examined anticipatory brain potentials and behavioral responses (reaction time; RT) to anticipated target stimuli in relation to individual differences in the ability to use goals to direct action (as indexed by measures of executive function; EF). A cross-sectional investigation was conducted in 40 adults (aged 18–25 years) and 40 children (aged 6–8 years) to examine the association of changes in the amplitude of modality-specific alpha-range rhythms in the electroencephalogram (EEG) during anticipation of lateralized visual, tactile, or auditory stimuli with inter- and intraindividual variation in RT and EF. Children and adults exhibited contralateral anticipatory reductions in the mu rhythm and the visual alpha rhythm for tactile and visual anticipation, respectively, indicating modality and spatially specific attention allocation. Variability in within-subject anticipatory alpha lateralization (the difference between contralateral and ipsilateral alpha power) was related to single-trial RT. This relation was more prominent in adults than in children, and was not apparent for auditory stimuli. Multilevel models indicated that interindividual differences in anticipatory mu rhythm lateralization contributed to the significant association with variability in EF, but this was not the case for visual or auditory alpha rhythms. Exploratory microstate analyses were undertaken to cluster global field power (GFP) into a distribution-free temporal analysis examining developmental differences across samples and in relation to RT and EF. Anticipation is suggested as a developmental bridge construct connecting neuroscience, behavior, and cognition, with anticipatory EEG oscillations being discussed as quantifiable and potentially malleable indicators of stimulus prediction.  相似文献
