SOLITARY TOY PLAY AND TIME OUT: A FAMILY TREATMENT PACKAGE FOR CHILDREN WITH AGGRESSIVE AND OPPOSITIONAL BEHAVIOR

The behavior of four boys, 5 to 8 years of age, who were referred for a number of oppositional, rule violating, and aggressive behaviors, was assessed by direct observation and parent reports. Following baseline measurement, several interventions were successively applied to each child's behavior. Use of a social play contract to reduce problem behaviors by teaching appropriate social behaviors resulted either in no improvement or in worsening of the problem behaviors in observations made when the contract was not in effect. Changing the contract behavior to solitary toy play resulted in reduced oppositional behavior during the observation sessions, fewer reports from the parents of low-rate problem behaviors, and improvements in the parents' attitudes toward the children. However, these changes during the observation sessions were shortlived, because the data on these measures began to show a reversal during later sessions. Inclusion of a time-out contingency with the solitary play contract recovered the earlier improvements in the children's behavior during observation sessions and the parents' reports. These results gave support to the view that for children whose behavior is severely oppositional and aggressive, a treatment approach emphasizing productive, solitary behaviors may be superior to one stressing appropriate social interaction. However, a combined strategy of reinforcement for solitary play and punishment for problem behaviors appears necessary to ensure more durable treatment effects.     

GENERALIZED IMITATION AND RESPONSE-CLASS FORMATION IN CHILDREN WITH AUTISM

An experimental analysis of imitation was conducted to examine the influence of response topography on generalization of imitation across three response types. Four children with autism were presented with both reinforced training trials and nonreinforced probe trials of models from vocal, toy-play, and pantomime response types. The probe trials were used to examine generalization within each response type. A multiple baseline design was used to analyze percentage of matching and nonmatching responses to models across response types. This study, the first to analyze imitative response classes in children with autism, showed that imitation generalized from reinforced training models to nonreinforced probe models within a response type, but it did not generalize across response types. Thus, functional response classes determined by topographical boundaries were exhibited within generalized imitation.     

Dyadic association between aggressive pretend play and children’s anger expression

This study investigates the association between children’s peer-reported expression of anger and their pretend play with aggressive/negative themes observed during spontaneous play with classmates. Participants comprised 104 Chinese children (M_age = 8.98 years, SD = 0.97, 49% girls) and were filmed playing in peer dyads with toys. Aggressive and non-aggressive negative pretend themes were coded at five-second intervals for 10 minutes. Children’s expression of anger in real situations was reported by peers. Analysis using actor–partner interdependence modelling (APIM) revealed significant partner effects, indicating that children were more likely to engage in pretend play with aggressive themes when they were playing with a partner who was perceived by their peers as more easily angered. It was also found that boys were more likely to engage in pretend play with both aggressive and non-aggressive negative themes compared with girls.     

Vocal signals only impact speakers’ own emotions when they are self-attributed

Emotions are often accompanied by vocalizations whose acoustic features provide information about the physiological state of the speaker. Here, we ask if perceiving these affective signals in one’s own voice has an impact on one’s own emotional state, and if it is necessary to identify these signals as self-originated for the emotional effect to occur. Participants had to deliberate out loud about how they would feel in various familiar emotional scenarios, while we covertly manipulated their voices in order to make them sound happy or sad. Perceiving the artificial affective signals in their own voice altered participants’ judgements about how they would feel in these situations. Crucially, this effect disappeared when participants detected the vocal manipulation, either explicitly or implicitly. The original valence of the scenarios also modulated the vocal feedback effect. These results highlight the role of the exteroception of self-attributed affective signals in the emergence of emotional feelings.     

注视者及观察者因素对注视知觉的影响

注视知觉既包括识别他人对周围环境的注视位置, 也包括对他人是否在注视自己(即直视)的感知。诸多研究表明, 注视知觉过程受来自目光发出者与感知者多种因素的影响。从眼神沟通中不同角色角度出发, 将这些影响因素分为注视者因素和观察者因素。具体而言, 注视者因素主要探讨了眼部及头部物理特征及面孔情绪与吸引力对注视知觉的影响。而观察者因素则探讨了个体的心理或精神障碍、个体当前状态特征及观察者的性别、种族及文化差异对注视知觉的影响。未来研究可以从创新实验设计与任务出发, 探讨注视者刺激的实验材料与观察者特征的临床应用及跨文化差异等方面的问题。     

Young children's television viewing and the quality of their interactions with parents: A prospective community study

Television is one of the most commonly viewed forms of media by children throughout the world. Excessive television viewing can influence the quality of children's relationships and interactions with their parents. We examined the emotional availability (EA ) of children toward their parents by assessing child responsiveness and child involvement , using a cross‐sectional and longitudinal design. We employed a large and representative community sample of Norwegian 4‐year‐olds (n = 995) who were followed up at 6 years old (n = 795). The results illustrate that, when viewing excessive amounts of television, children are less likely to be involved with their parents in ordinary toy‐play. We argue in favor of the displacement hypothesis, stating that time‐demanding technologies are negatively related to the quality of parent–child relationships because spending more time watching television will leave less time for developing nurturing social relationships.
