Cognitive function in adolescents with chronic fatigue syndrome

This thesis explored cognitive function in adolescents with chronic fatigue syndrome. Counter to what has been found in adults, adolescents with CFS performed as well as their peers on demanding tests of executive function, information processing, memory and attention. The results suggest that CFS might impact differently on the developing brain. The portfolio used a case study approach to examine the effectiveness and utility of Finn's Therapeutic Assessment model in four clients.

Simulation-based learning for control of complex conveyor networks

This research investigated the problem of path planning in complex conveyor networks. A reinforcement learning approach was applied to derive a control strategy for routing traffic. The derived strategy was verified in real world systems and was found to improve network performance by prioritising traffic flows and balancing network load.

A framework for re-thinking learning in science from recent cognitive science perspectives

Recent accounts by cognitive scientists of factors affecting cognition imply the need to reconsider current dominant conceptual theories about science learning. These new accounts emphasize the role of context, embodied practices and narrative-based representation rather than learners’ cognitive constructs. In this paper we analyze data from a longitudinal study of primary school children’s learning to outline a framework based on these contemporary accounts, and to delineate key points of difference from conceptual change perspectives. The findings suggest this framework provides strong theoretical and practical insights into how children learn and the key role of representational negotiation in this learning. We argue that the nature and process of conceptual change can be re-interpreted in terms of the development of students’ representational resources.

Differences in student engagement : investigating the role of the dominant cognitive processes preferred by engineering and education students

This paper reports on a study of the differences in the dominant cognitive processes preferred by groups of engineering and education students and examines the implications of these differences for the assessment of student engagement with university courses. Concern is expressed that the items commonly used to capture student engagement data do not adequately cover the full range of the dominant cognitive processes preferred by tertiary students. The paper sets out a brief overview of student engagement along with the theory of dominant and auxiliary cognitive processes, as developed by Jung and later by Myers. Evidence is presented of the differing frequencies of the eight cognitive processes, as assessed by the Myers-Briggs Type Indicator, that are preferred by cohorts of students undertaking courses in engineering and education. The implications of these differences are discussed in the context of subject disciplines in university environments.

Cognitive distortions in child molesters : theoretical and research developments over the past two decades

Cognitive distortions have become an important focus for professionals working with child molesters since the early 1980s. In this paper, we describe and discuss both the theoretical and methodological developments of child molester's cognitive distortions that have evolved over the past two decades. We conclude that although theory and research development has been a little slow in this topic, several interesting theoretical and methodological developments have been made in recent years. We describe how we believe such developments will further increase the conceptual clarity of cognitive distortions and provide some suggestions for other future developments in this field.

Identification of five fundamental implicit theories underlying cognitive distortions in child abusers : a preliminary study

Qualitative analysis of interviews with 22 child abusers found strong evidence for Ward and Keenan's (1999) proposal that there are five implicit theories in child abusers that account for the majority of their cognitive distortions/thinking errors. These implicit theories are: Child as a sexual being where children are perceived as being able to and wanting to engage in sexual activity with adults and also are not be harmed by such sexual contact; Nature of harm where the offender perceives that sexual activity does not cause harm (and may in fact be beneficial) to the child; Entitlement where the child abuser perceives that he is superior and more important than others: and hence is able to have sex with whoever, and whenever, he wants; Dangerous world where the offender perceives that that others are abusive and rejecting and he must fight to regain control; and Uncontrollable where the offender perceives the world as uncontrollable and hence he believes that circumstances are outside of his control. There was no evidence for any other type of implicit theory. Results of the study also indicated that there was a significant difference in terms of the endorsement of the Dangerous world implicit theory between participants reporting a history of child sexual abuse and those who did not. Offenders against male victims were significantly more likely to endorse the Child as a sexual being and Dangerous world implicit theories compared to men who had offended against female children.
