Previous research has shown that anxious adults provide more threat interpretations of ambiguous stimuli than other clinic and nonclinic persons. We were interested in investigating if the same bias occurs in anxious children and how family processes impact on these children's interpretations of ambiguity. Anxious, oppositional, and nonclinical children and their parents were asked separately to interpret and provide plans of action to ambiguous scenarios. Afterwards, each family was asked to discuss two of these situations as a family and for the child to provide a final response. The results showed that anxious and oppositional children were both more likely to interpret ambiguous scenarios in a threatening manner. However, the two clinic groups differed in that the anxious children predominantly chose avoidant solutions whereas the oppositional children chose aggressive solutions. After family discussions, both the anxious children's avoidant plans of action and the oppositional children's aggressive plans increased. Thus, this study provides the first evidence of family enhancement of avoidant and aggressive responses in children. These results support a model of anxiety that emphasizes the development of an anxious cognitive style in the context of anxiety-supporting family processes.
Barrett, Rapee, Dadds, and Ryan (1996) described a phenomenon whereby family discussions magnified the style of children's problem solving in a way characteristic of their particular clinical diagnosis. That is, anxious children became more avoidant, aggressive children more aggressive, and nonclinic children more prosocial, after discussing ambiguous hypothetical situations with their parents. This study examined specific sequences of communications exchanged between parents and children hypothesized to underlie this family exacerbation of child cognitive style. Family discussions were videotaped and categorized for groups of anxious, aggressive, and nonclinic children and their parents. Results revealed differences between groups of parents in frequency of agreeing with and listening to their child and the frequency of pointing out positive consequences. Conditional probability analyses showed that parents of anxious children were more likely to reciprocate avoidance, while parents of nonclinic children were more likely to agree with and listen to prosocial plans from their child. Differences in parent behaviors observed during the family discussions were reliably associated with the child's response to the ambiguous situation proposed after the family discussion. Results support a model of developmental anxiety and aggression that emphasizes the interaction of family processes and social-cognitive development in the child.
Context: Sharing expert knowledge is a key process in developing software products. Since expert knowledge is mostly tacit, the acquisition and sharing of tacit knowledge along with the development of a transactive memory system (TMS) are significant factors in effective software teams. Objective: We seek to enhance our understanding human factors in the software development process and provide support for the agile approach, particularly in its advocacy of social interaction, by answering two questions: How do software development teams acquire and share tacit knowledge? What roles do tacit knowledge and transactive memory play in successful team performance? Method: A theoretical model describing the process for acquiring and sharing tacit knowledge and development of a TMS through social interaction is presented and a second predictive model addresses the two research questions above. The elements of the predictive model and other demographic variables were incorporated into a larger online survey for software development teams, completed by 46 software SMEs, consisting of 181 individual team members. Results: Our results show that team tacit knowledge is acquired and shared directly through good quality social interactions and through the development of a TMS with quality of social interaction playing a greater role than transactive memory. Both TMS and team tacit knowledge predict effectiveness but not efficiency in software teams. Conclusion: It is concluded that TMS and team tacit knowledge can differentiate between low-and high-performing teams in terms of effectiveness, where more effective teams have a competitive advantage in developing new products and bringing them to market. As face-to-face social interaction is key, collocated, functionally rich, domain expert teams are advocated rather than distributed teams, though arguably the team manager may be in a separate geographic location provided that there is frequent communication and effective use of issue tracking tools as in agile teams.
In this paper we operationally define and measure tacit knowledge at the team level in the software development domain. Through a series of three empirical studies we developed and validated the Team Tacit Knowledge Measure (TTKM) for software developers. In the first study, initial scale items were developed using the repertory grid technique and content analysis. In Study 2, supplied repertory grids were administered to novices and experts to establish differential items, and Study 3 validated the TTKM on a sample of 48 industrial software development teams. In developing the TTKM we explored the relationships between tacit knowledge, explicit job knowledge and social interaction and their effect on team performance as measured by efficiency and effectiveness. In addition we assess the implications for managing software development teams and increasing team performance through social interaction.
A 3-group reading-level design was used to investigate phonological analysis, verbal working memory, and pseudoword reading performance in less skilled fourth-grade readers. Children were given phonological oddity tasks assessing their sensitivity to subsyllabic and phonemic units, together with standardized tests of verbal working memory and pseudoword reading. Less skilled fourth-grade readers performed lower than both chronological age and reading-level controls on the phonological oddity and pseudoword reading tests. Less skilled fourth-grade readers performed at the same level as skilled second-grade readers on a test of verbal working memory. Skilled fourth-grade readers scored higher than both other groups on this test. Correlational analyses were consistent with the view that phonological analysis skills contribute more strongly than verbal working memory skills to children's decoding abilities.
