“After the group had played [improvisation] game[s]…colours became brighter, people and spaces seem of a different size, focus is sharper. Our normal thinking dulls perception…” Keith Johnstone (1979, pg. 131) Improvisation is considered to be both the process and product of creativity. It involves the creation of new ideas, on the spur of the moment that are novel and unplanned. Spontaneity, the ability to do something on the spot with no prior preparation is seen as a key element of improvisation and distinction in relation to creativity. The process of improvisation involves thinking in different ways and as a result, could influence our thought processes. It is important to note here that while we are interested in the process of improvisation, it is only possible to measure this through the product. The product is therefore seen as a direct outcome of the process of thinking that occurs during improvisation. It has been suggested that improvisation could relate to cognitive processes (Karakelle, 2009; Schmidt, Goforth & Drew, 1975; Scott, Harris & Rothe, 2001). This program of research therefore aims to identify the cognitive changes in relation to the process of improvisation. This is measured by looking at cognitive tasks pre and post improvisation. Several studies were therefore conducted investigating the effects of improvisation on various cognitive abilities, with a focus on differences between divergent and convergent thinking; (i) the Effect of Verbal Improvisation on Mood, Creativity and Cognition; (ii) verbal improvisation in relation to divergent and convergent thinking; (iii) dance improvisation in relation to divergent and convergent thinking; (iv) Divergent thinking; Differences among expert and novice improvisers and (v) length of Treatment; Cognitive effects following a shorter improvisation treatment length. As a result of the above experiments, results were extended to a clinical sample of Parkinson’s disease. An extensive investigation was also carried out investigating the scoring of method of the Alternative Uses Task (AUT; Guilford, 1957b). Furthermore, the level of cognitive load as a result of improvisation was investigated by observing gesture in improvisation. Taken together, results showed that after a series of verbal improvisation activities, participants improved in scores of divergent thinking tasks. However, this was not observed in scores of convergent thinking tasks. Issues surrounding reliability of the scoring method of the AUT were also discussed. However, this did not affect the consistency of the results observed in this program of research. A theory of schemas was applied to the process of improvisation as a result of the cognitive changes that occured, such that improvisation helps people think in more original and flexible ways by improving access to schemas and working memory.

Traditional classrooms in which children are expected to sit down quietly and listen to the teacher are not attractive to students in the era of technology. Therefore, researchers have started to study the possibilities of applying modern approaches to educational contexts. The interactive nature and the attractive virtual environment of computer games have made them a high-potential context for learning purposes. Sitting in a classroom is challenging for students with Attention Deficit Hyperactivity Disorder (ADHD)because of their inattentiveness, impulsivity, and hyperactivity, so that they distract easily.However, researchers have discovered that children with ADHD are not distracted when playing computer games. Therefore, computer games can be beneficial learning contexts that can attract ADHD children’s attention in order to teach them. So far, a large number of studies have been conducted to help ADHD children. Some researchers have worked on cognitive-training approaches to improve skills such as eye gaze, emotion recognition, and working memory enhancement of ADHD children. In addition to the core deficits associated with ADHD, children with ADHDalso face difficulties in social situations, because they are not equipped with the required social skills. Therefore, they face many problems in society that they cannot solve. Consequently, they face peer rejection or social isolation and other mental health problems. Social problem solving is a step-by-step process. For ADHD children, learning the different steps of social problem solving is difficult because they are inattentive. Moreover, acting upon the steps is also hard for ADHD children because they are impulsive. We developed a simulation game, named TARLAN, wherein different steps of solving a social problemare taught to ADHD children. We designed and developed real life scenarios in which children can practise, in order to enable them to apply what they have learnt from the game to real-life situations.TARLAN was designed in three phases, from the elementary level to more advanced levels in order to help the ADHD child gradually become an independent problem solver in society. That happens by building strong scaffolding around the child’s learning on the elementary level and remove it in the more advanced levels. This scaffolding/levelling within games has positive learning outcomes. Forty children with ADHD aged 8-12 were randomly allocated to two interventions, a computer-based intervention in which children worked with TARLAN and another intervention which was a standard psychological intervention. We also had a control group in which 20 children without ADHD also worked with TARLAN. The effectiveness of our game in improving social skills as well as problem behaviour of ADHD children was evaluated using the Social Skills Improvement System (SSIS), which is a standard psychologicalmeasure. The results of the SSIS showed that TARLANimproves children’s social acquisition and problem behaviour significantly more than a more expensive standard intervention led by a psychologist (role playing).Moreover, after analysingdata collected during the study,we found out that TARLANimproved children’s performance: the ADHD children reached the same performance level as children without ADHD after working with the game. These results open up the possibility of using games as helpful tools in teaching important life-changing subjects that are hard for ADHD children to learn from traditional approaches. Therefore, the educational life of ADHD children can be changedfrom a challenging experience into a rewarding and attractive experience and time and money can be saved.

The purpose of these investigations was to compare changes in child conduct problem behavior and parental ability and to examine the relationship between parent and child outcome. An A/B research design was used across two studies with a total of 34 children (aged 3--10 years) and 43 parents randomly assigned to one of three parent-mediated treatment modalities (i.e., individualized conjoint behavioral consultation using a self-administered treatment manual; CBC, group-administered videotape parent training with shared consultant contact; GVT, and self-administered videotape parent training with minimal consultant contact; VT). In the first study, child outcome was evaluated using direct observations of target behavior, along with pretreatment and posttreatment estimates of problem behavior on standardized instruments. Both single- n and group analyses were used for analysis of data. The results indicated that 77%, 50%, and 75% of children in the CBC, GVT and VT groups respectively, evidenced at a minimum, small improvements in their conduct problem target behaviour. In addition, parents reported global improvements in children's problem behavior. No differential effects of treatment group, however, were detected. A second study was carried out to examine the mediating factors thought to produce children's behavioral improvements. Outcome was evaluated for parents through the use of observed child-management skills during parent-child play interactions and by using pretreatment and posttreatment estimates of parental knowledge of behavioral principles and attitudes toward parenting (i.e., satisfaction, involvement and limit setting). Further, children's level of deviancy (e.g., noncompliance) was examined during parent-child play interactions. Results of single-n analyses varied depending on the parent variable examined, however group analyses revealed improvements in parental use of several child management skills and in parental knowledge. For the children, ind
