Effects of Developmental Task Constraints on Kinematic Synergies during Catching in Children with Developmental Delays

Abstract

The aim of this study was to examine effects of a task intervention on kinematic synergies in catching. Participants were young children (5.58?±?0.52?years) with the lowest scores on two-hand catching, according to assessments with the Test of Gross Motor Development-2 (TGMD-2) and were allocated into two groups. The constraints group took part in an 8-week intervention, whereas the control group experienced a typical physical education. Both groups were assessed with motor development and kinematic coordination measures with a catching task with a ball thrown from 2?m distance. Kinematic variables were recorded using a wireless motion capture system. A principal component analysis (PCA) was used to measure the kinematic synergies formed among active body parts. Two synergies that emerged in catching were mainly utilised for “reaching” and “catching” the ball. The control group tended to re-organise the majority of active body parts into two functional units in all phases, whereas the constraints group adapted their active parts into functional units according to the requirement of the novel movement in the transfer task. The findings of this study suggested that task constraints could facilitate object control by re-organisation of active body parts into functional synergies to achieve successful performance.     

Interpretation of ambiguous emotional information in clinically anxious children and adolescents

Cognitive theories of anxiety based on adult data predict that individuals vulnerable to anxiety should show threat - related interpretations of ambiguous material and it is proposed that this is an important maintaining factor in anxiety disorders. In the present study, interpretation of ambiguous emotional/neutral information was examined in child and adolescent anxious patients. Two groups of participants, anxious patients (n = 17) and healthy controls (n = 40), were presented with a series of homographs, each with a threatening and a neutral interpretation. For each homograph, the participants were asked to construct a sentence using the homograph. Anxious children and adolescents produced significantly more sentences consistent with threatening homograph interpretations and less consistent with neutral interpretations than did normal controls. Regression analyses revealed no relationship between age and this interpretive bias. Preliminary developmental and theoretical implications are discussed.     

Learning to be mindful of difference: teaching systemic skills in cross‐cultural encounters

In this paper the author shares some of his experiences of teaching in areas of ‘race’ and culture to mainly white middle‐class family therapy and clinical psychology trainees. He presents a framework for a systemic teaching session on working interculturally. Specific exercises are described that trainers can use to design a new session or incorporate into existing ones. It is meant to increase the cultural awareness and sensitivity of trainees with limited experience of cross‐cultural therapeutic work.     

The relationships between religiosity,prosociality, satisfaction with life and generalised anxiety: a study on Turkish Muslims

ABSTRACT

The reason for research on Muslim samples is the perceived weakness in existing measures of prosocial behaviours. The current study's three aims are: Developing a suitable prosociality scale, examining the links between religiosity, prosociality, anxiety, and satisfaction with life, and investigating the mediating roles of anxiety and prosociality on the link between religiosity and satisfaction with life. The sample consists of 678 Turkish Muslims, 428 females and 250 males, ranged from 14 to 56, with mean age of 31 (SD?=?8,973). In the current study, the Individual Religion Inventory, the Turkish Prosociality Scale (TPS), the Satisfaction with Life Scale, and the Generalised Anxiety Scale are applied to the sample. Findings of the correlation matrix indicated positive correlations between religiosity, prosociality and satisfaction with life, and demonstrated that anxiety is related negatively to religiosity and life satisfaction. According to the path analysis, prosociality and anxiety mediate the link between religiosity and satisfaction with life.     

Young children's ability to recognize advertisements in web page designs

Identifying what is, and what is not an advertisement is the first step in realizing that an advertisement is a marketing message. Children can distinguish television advertisements from programmes by about 5 years of age. Although previous researchers have investigated television advertising, little attention has been given to advertisements in other media, even though other media, especially the Internet, have become important channels of marketing to children. We showed children printed copies of invented web pages that included advertisements, half of which had price information, and asked the children to point to whatever they thought was an advertisement. In two experiments we tested a total of 401 children, aged 6, 8, 10 and 12 years of age, from the United Kingdom and Indonesia. Six‐year‐olds recognized a quarter of the advertisements, 8‐year‐olds recognized half the advertisements, and the 10‐ and 12‐year‐olds recognized about three‐quarters. Only the 10‐ and 12‐year‐olds were more likely to identify an advertisement when it included a price. We contrast our findings with previous results about the identification of television advertising, and discuss why children were poorer at recognizing web page advertisements. The performance of the children has implications for theories about how children develop an understanding of advertising.
