Peer-directed behaviors of toddlers were longitudinally recorded in a naturalistic preschool setting. An observer (O, the first author) recorded children's behaviors during play sessions with an IC recorder. One-year-old children (N = 13) and children under the age of 12 months (N = 8) were observed for 15 min, 6 times in a year. Their teaching, caring, and altruistic behaviors were analyzed in detail. Results indicated that peer-directed behaviors of one-year-olds increased dramatically. It is concluded that toddlers are sophisticated social being.  相似文献

This study examined the continuous interpersonal interactions of performers in dyadic systems in team sports, as a function of changing information constraints. As a task vehicle, we investigated how attackers attained success in 1v1 sub-phases of basketball by exploring angular relations with immediate opponents and the basket. We hypothesized that angular relations would convey information for the attackers to dribble past defenders. Four basketball players performed as an attacker and defender in 1v1 sub-phases of basketball, in which the co-positioning and orientation of participants relative to the basket was manipulated. After video recording performance behaviors, we digitized participant movement displacement trajectories and categorized trials as successful or unsuccessful (from the attackers’ viewpoint). Results revealed that, to successfully dribble past a defender, attackers tended to explore the left hand side of the space by defenders by increasing their angular velocity and decreasing their angular variability, especially in the center of the court. Interpersonal interactions and goal-achievement in attacker–defender dyads appear to have been constrained by the angular relations sustained between participants relative to the scoring target. Results revealed the functionality of exploratory behaviors of participants attempting re-align spatial relations with an opponent in 1v1 sub-phases of team games.  相似文献

The Need Inventory of Sensation Seeking (NISS) by Roth and Hammelstein (2012) conceptualizes sensation seeking as a motivational trait, a need for stimulation that can provoke different behaviors. Extending the area of application to the field of sexuality, the results of an online survey with a convenience sample (N = 368) provided evidence that the NISS outperforms traditional measures of sensation seeking. In a series of hierarchical regression analyses, the NISS added incremental variance in predicting the number of sexual partners and the frequency of extreme sexual behaviors and fantasies. No relationship between the NISS and pornography use was found. Moreover, the NISS subscale Need for Stimulation performed better than the subscale Avoidance of Rest. Overall, the study supported the assumption that the NISS is a valid and reliable instrument in the area of sexuality.  相似文献

Perceived ethnic discrimination (PED) is associated with increased engagement in risky behaviors in ethnic minority emerging adults. Risky behaviors may reflect efforts to cope with emotional distress like depression or anxiety resulting from PED, particularly for individuals with poor emotion regulation skills. We hypothesized that the association between PED and risky behaviors would be particularly strong for emerging adults with tendencies for angry rumination. We further hypothesized that increased depressive and anxious symptoms would mediate the effect of the PED-rumination interaction on risky behaviors. In this survey study, 155 ethnic minority college students completed measures of PED, depressive and anxiety symptoms, trait angry rumination, and risky behaviors. Analyses revealed that angry rumination moderated the association between PED and greater risky behaviors. Depressive and anxiety symptoms did not mediate this effect. Although cross-sectional, these findings suggest that individuals with poor coping skills may be especially likely to respond to stressors such as PED by engaging in risky behaviors. Implications include using rumination-focused interventions in order to prevent engagement in risky behaviors in ethnic minority emerging adults.  相似文献

Repetitive self-injurious eye poking and stereotypic hand clapping were assessed in a child with autism and hearing impairment. A functional behavioral assessment conducted to identify the variables maintaining eye-poking behaviors indicated automatic reinforcement. Choice and environmental enrichment strategies were implemented to decrease the motivating operations associated with eye poking. Providing a choice of toys to hold in his hand led to the greatest reductions in both repetitive eye poking and hand clapping. Three follow-up observations were conducted 9 months after the intervention, which indicated that eye poking was eliminated and hand clapping was greatly reduced. This antecedent intervention was simple and effective, two hallmarks of sustainable behavior interventions.  相似文献

ObjectiveMany people do not behave in line with their self-imposed goal to be more physically active. To bridge this intention–behavior gap, detailed planning is regarded as being instrumental. Moreover, preparatory actions are supposed to facilitate physical activity in conjunction with planning. Thus, preparatory actions are seen as mediators between intention and behaviors. The present study examines whether intention is translated into physical activity stepwise via planning as well as via preparatory actions.DesignAt three points in time, physical activity, planning, preparatory actions, and the intention to be physically active were assessed in 338 participants.MethodsBy means of structural equation modeling, it was examined whether the pathway from intention to physical activity includes a mediating sequence of planning as well as preparatory actions.ResultsThe sequential mediation model confirmed pathways from intention to planning, from planning to preparatory behaviors, and from preparatory behaviors to follow-up physical activity, while controlling for baseline indicators. Furthermore, there was an indirect effect of intention on preparatory actions via planning, an indirect effect of planning on physical activity via preparatory actions, and an indirect effect of intention on physical activity via planning and preparatory actions thus, confirming the hypothesized sequence.ConclusionsIndividuals who are motivated to be physically active are likely to make a plan, and if they do so, they are more likely to take preparatory actions, resulting in a higher chance to perform the target behavior.  相似文献

运用同伴提名法、问卷法对82个班级4654名初中生的个体行为、朋友数量及学业成绩进行了测量,并用多层线性模型(HLM)对数据进行了分析处理。研究结果表明,在个体水平上,初中生的朋友数量和学业成绩对受欺负状况有明显的负向预测效果,初中生的攻击和退缩行为对受欺负状况有明显的正向预测效果。在班级水平上,班级的攻击行为范式可以减弱攻击行为和受欺负状况间的正向联系,增强退缩行为和受欺负状况间的正向关联;而班级的退缩行为范式则可以强化攻击和受欺负状况间的正向联系,弱化退缩行为与受欺负状况间的正向关联。  相似文献

小学儿童尊重行为与人格、班级环境的关系   总被引:3,自引:0,他引:3  
以356名北京市两所小学三、四、五年级的小学儿童为被试,采用自编的小学儿童尊重行为问卷、国内修订的学生人格五因素问卷和班级环境问卷,考察小学儿童尊重行为的特点,并探讨人格和班级环境对尊重行为的影响.结果发现:(1)小学儿童的总体尊重行为和其中的理解欣赏具有显著的性别差异和城郊差异;(2)尊重行为与人格各维度具有显著的相关,与班级环境中除了竞争气氛之外的其他四个维度都有显著相关;(3)人格的宜人性、谨慎性、情绪性和开放性以及班级环境中的同学关系能够显著预测尊重行为,人格和班级环境的不同维度对于尊重行为不同维度具有不同的预测力;(4)小学儿童的班级环境可以归为三种类型:积极型、一般型和问题型,不同类型的班级环境在尊重行为上具有显著差异.  相似文献

幼儿社会行为发展特点的研究   总被引:13,自引:3,他引:10  
本研究采用随机抽样法对12个小、中、大班共435名幼儿社会行为的发展特点进行了研究。结果表明,幼儿积极行为和消极行为在数量和质量上均存在一定差异;幼儿积极行为和消极行为内部不同行为间的发展具有一致性与差异性;在幼儿不同类型的社会行为的发展中,自然因素与环境教育因素在儿童发展不同阶段起着不同作用。幼儿社会行为发展存在显著的性别差异。  相似文献

家庭功能与青少年问题行为关系的追踪研究   总被引:5,自引:2,他引:3  
选取北京市三所中学620名初一和初二的学生为被试,采用追踪调查的方式,先后两次(间隔为九个月)让被试报告其家庭功能和问题行为,以探讨青少年家庭功能和问题行为的发展变化情况,以及家庭功能与青少年问题行为的因果关系。研究发现:(1)青少年的家庭功能和问题行为均存在一定的稳定性,但在任务完成、沟通和卷入方面存在变化,均为后测功能不如前测功能;而危害健康行为随着年龄的增长呈显著下降趋势。(2)家庭功能的每个方面均与青少年问题行为呈显著相关,即家庭功能发挥越好,青少年的问题行为也相应越少。(3)交叉滞后回归分析的结果表明,在更大程度上是家庭功能影响着少年的问题行为,进一步回归分析表明,家庭功能中的卷入维度对青少年问题行为具有显著的预测作用。  相似文献
