Investigating a robot as a therapy partner for children with autism

The aurora project is investigating the possibility of using a robotic platform as a therapy aid for--children with autism. Because of the nature of this disability, the robot could be beneficial in its ability--to present the children with a safe and comfortable environment and allow them to explore and learn--about the interaction space involved in social situations. The robotic platform is able to present--information along a limited number of channels and in a manner which the children are familiar with--from television and cartoons. Also, the robot is potentially able to adapt its behaviour and to allow the--children to develop at their own rates. Initial trial results are presented and discussed, along with the--rationale behind the project and its goals and motivations. The trial procedure and methodology are--explained and future work is highlighted.

Can social interaction skills be taught by a social agent? The role of a robotic mediator in autism therapy

Increasingly socially intelligent agents (software or robotic) are used in education, rehabilitation and therapy. This paper discusses the role of interactive, mobile robots as social mediators in the particular domain of autism therapy. This research is part of the project AURORA that studies how mobile robots can be used to teach children with autism basic interaction skills that are important in social interactions among humans. Results from a particular series of trials involving pairs of two children and a mobile robot are described. The results show that the scenario with pairs of children and a robot creates a very interesting social context which gives rise to a variety of different social and non-social interaction patterns, demonstrating the specific problems but also abilities of children with autism in social interactions. Future work will include a closer analysis of interactional structure in human-human and robot-human interaction. We outline a particular framework that we are investigating.

A micro-level simulation for the prediction of intention and behaviour

In this contribution we aim at anchoring Agent-Based Modeling (ABM) simulations in actual models of human psychology. More specifically, we apply unidirectional ABM to social psychological models using low level agents (i.e., intra-individual) to examine whether they generate better predictions, in comparison to standard statistical approaches, concerning the intentions of performing a behavior and the behavior. Moreover, this contribution tests to what extent the predictive validity of models of attitude such as the Theory of Planned Behavior (TPB) or Model of Goal-directed Behavior (MGB) depends on the assumption that peoples’ decisions and actions are purely rational. Simulations were therefore run by considering different deviations from rationality of the agents with a trembling hand method. Two data sets concerning respectively the consumption of soft drinks and physical activity were used. Three key findings emerged from the simulations. First, compared to standard statistical approach the agent-based simulation generally improves the prediction of behavior from intention. Second, the improvement in prediction is inversely proportional to the complexity of the underlying theoretical model. Finally, the introduction of varying degrees of deviation from rationality in agents’ behavior can lead to an improvement in the goodness of fit of the simulations. By demonstrating the potential of ABM as a complementary perspective to evaluating social psychological models, this contribution underlines the necessity of better defining agents in terms of psychological processes before examining higher levels such as the interactions between individuals.

Considering user attitude and behaviour in persuasive systems design: the 3D-RAB model

As in any technology systems, analysis and design issues are among the fundamental challenges in persuasive technology. Currently, the Persuasive Systems Development (PSD) framework is considered to be the most comprehensive framework for designing and evaluation of persuasive systems. However, the framework is limited in terms of providing detailed information which can lead to selection of appropriate techniques depending on the variable nature of users or use over time. In light of this, we propose a model which is intended for analysing and implementing behavioural change in persuasive technology called the 3D-RAB model. The 3D-RAB model represents the three dimensional relationships between attitude towards behaviour, attitude towards change or maintaining a change, and current behaviour, and distinguishes variable levels in a user’s cognitive state. As such it provides a framework which could be used to select appropriate techniques for persuasive technology.

Biased interpretation in perfectionism and its modification

Perfectionism is a transdiagnostic construct associated with a range of diagnoses, including depression, eating disorders and obsessive compulsive disorder. Treatments that directly target perfectionist cognitions have been shown to successfully reduce associated pathologies. However, the way in which they do this is not clear. We set out to assess the role of one candidate mechanism of action, namely the cognitive process of interpretation of ambiguity. In one experiment we looked for associations between biased interpretation and perfectionism. In a second, we manipulated interpretations, thereby providing a strong test of their aetiological significance. Results from the first experiment confirmed the presence of biased interpretation in perfectionism and demonstrated that these are highly specific to perfection relevant information, rather than reflecting general negativity. The second experiment succeeded in manipulating these perfection relevant interpretations and demonstrated that one consequence of doing so is a change in perfectionist behaviour. Together, these data experimentally demonstrate that biased interpretation of perfection relevant ambiguity contributes to the maintenance of perfectionism, but that it is also possible to reverse this. Clinical implications include the identification of one likely mechanism of therapeutic change within existing treatments, as well as identification of an appropriate evidence based focus for future treatment development. Targeting underlying functional mechanisms, such as biased interpretation, has the potential to offer transdiagnostic benefits.

Clinical implications of cognitive bias modification for interpretative biases in social anxiety: an integrative literature review

Cognitive theories of social anxiety indicate that negative cognitive biases play a key role in causing and maintaining social anxiety. On the basis of these cognitive theories, laboratory-based research has shown that individuals with social anxiety exhibit negative interpretation biases of ambiguous social situations. Cognitive Bias Modification for interpretative biases (CBM-I) has emerged from this basic science research to modify negative interpretative biases in social anxiety and reduce emotional vulnerability and social anxiety symptoms. However, it is not yet clear if modifying interpretation biases via CBM will have any enduring effect on social anxiety symptoms or improve social functioning. The aim of this paper is to review the relevant literature on interpretation biases in social anxiety and discuss important implications of CBM-I method for clinical practice and research.

Can therapy dogs evoke awareness of one's past and present life in persons with Alzheimer's disease?

BACKGROUND: Persons with Alzheimer's disease (AD) sometimes express themselves through behaviours that are difficult to manage for themselves and their caregivers, and to minimise these symptoms alternative methods are recommended. For some time now, animals have been introduced in different ways into the environment of persons with dementia. Animal-Assisted Therapy (AAT) includes prescribed therapy dogs visiting the person with dementia for a specific purpose. AIM: This study aims to illuminate the meaning of the lived experience of encounters with a therapy dog for persons with Alzheimer's disease. METHOD: Video recorded sessions were conducted for each visit of the dog and its handler to a person with AD (10 times/person). The observations have a life-world approach and were transcribed and analysed using a phenomenological hermeneutical approach. RESULTS: The result shows a main theme 'Being aware of one's past and present existence', meaning to connect with one's senses and memories and to reflect upon these with the dog. The time spent with the dog shows the person recounting memories and feelings, and enables an opportunity to reach the person on a cognitive level. CONCLUSIONS: The present study may contribute to health care research and provide knowledge about the use of trained therapy dogs in the care of older persons with AD in a way that might increase quality of life and well-being in persons with dementia. IMPLICATIONS FOR PRACTICE: The study might be useful for caregivers and dog handlers in the care of older persons with dementia.

Testosterone replacement therapy-perceptions of recipients and partners

Background. The androgenic hormones are important determinants of sexual behaviour in men. Testosterone replacement is important treatment for pituitary disease to maintain normal functioning. Although the physical effects of testosterone replacement have been well documented, little is known about the effects on relationships, particularly from the point of view of the sexual partners of men receiving testosterone replacement.

Aims. This paper reports a study exploring the perceptions of testosterone replacement on well-being and sexual functioning.

Methods. Semi-structured interviews were conducted with five men receiving testosterone implants (recipients), their permanent partners, and five recipients without partners. Recipient serum testosterone concentration was measured at 0, 1 and 4 months after testosterone implantation.

Results. The three groups reported similar effects of testosterone on well-being and sexual functioning. Recipient and partner ratings were also similar. Strength was less affected by decreasing testosterone concentration than energy in men with partners, but both strength and energy declined in men without partners. Decreased testosterone levels had a statistically significantly different effect on libido at time zero between men with and without partners (P < 0·015) and on ability to sustain an erection, but the ability to achieve an erection persisted over the 6 months in both male groups. Intercourse frequency increased from once per week at time 0 to ≥3 per week between 1 and 4 months after implant in men with partners. There were important effects of testosterone deficiency on general and sexual relationships, and these differed between men with partners and those without.

Conclusions. Testosterone has important physical and psychological benefits that may be related to the age at which testosterone replacement commences and the indications for its use. The small sample size may limit the ability to generalize the findings outside the study.

Consumer complaint behaviour in sport consumption

While consumer complaint behaviour, and specifically voicing, has been extensively investigated from the perspective of goods (see Volkov et al., 2003, for a review), there have been fewer studies investigating consumer voicing with regard to services (Andreasen, 1984, 1985; Singh, 1988, 1990; Zeithaml, Berry, & Parasuraman, 1996). Further, no research can be identified in the extant literature with respect to experiential consumer voicing. This research proposes an examination of voicing behaviour of consumers in an experiential consumption setting and uses sport consumption as the context. A review of literature in the area is presented and a proposal for experiential research is offered.

In experiential consumption settings, consumers are more likely to experience emotional reactions to, and be actively involved in, the experience than in traditional consumption episodes (Addis & Holbrook, 2001; Hoffman, Kumar, & Novak, 2003; Lofman, 1991). Further, experiential consumption episodes
involve greater emotional processing, more activity, more evaluation, but less overall cognitive processing than traditional episodes (Lofman, 1991), which in turn is likely to result in different consumer behaviour in these experiential settings.

Tn this study, traditional consumer complaint behaviours are re-examined in an experiential context; specifically, consumption of live sport. It is proposed that these behaviours are not motivated by the traditional antecedents of anger and involvement and, further, that they are not enacted with the purpose of
reducing dissonance. Instead, it would appear that traditional complaint behaviour concepts such as voicing, overt aggression, and assignment of blame take on a more functional role in the sport consumption experience. The possibility exists that for some spectators these complaining behaviours that have traditionally been cJassitIed as negative, actually contribute to overall enjoyment o( and satisfaction with, a sport consumption experience.

A review of play and play assessment used in occupational therapy

In occupational therapy play is regarded as important in itself. This view has been influenced by occupational science and the assumption that play is a child's primary occupation. To reflect this change in the view of play, assessments of play are now being developed which focus on aspects of behaviour which are unique to play. As a result of this work on play, play training programs have been developed which focus on teaching children how to play.

Key behavioural and cognitive employee outcomes : a social exchange model

This paper serves to integrate social exchange with organisational justice and performance theory. Social exchange relationships are represented by employees’ perceptions of workplace inequity and evaluated using justice rules. Employees are expected to have in-role and extra-role behavioural responses and cognitive responses to inequity. It is theorised that behavioural and cognitive responses are moderated by the employee’s perceptions of organisational justice. Much employee performance, commitment, engagement, retention and turnover may be explained by this comprehensive model.

Treatment readiness in violent offenders : the influence of cognitive factors on engagement in violence programs

Advances in offender rehabilitation theory have led to the development of a clear framework of the factors that need consideration for an offender to be ready for therapy and thus gain maximum benefits. Here, we examine in greater detail the role of cognition in readiness for rehabilitation in violent offenders. We assess how cognitive processes and distortions common in violent offenders may affect and hamper rehabilitation readiness. Methods for remediation of cognitive factors that diminish readiness, including motivational interviewing, are discussed. We conclude that cognitive factors are critical in the assessment of readiness in violent offenders and therapeutic efforts to enhance engagement.

Do animals have cognitive maps?

Drawing on studies of humans, rodents, birds and arthropods, I show that 'cognitive maps' have been used to describe a wide variety of spatial concepts. There are, however, two main definitions. One, sensu Tolman, O'Keefe and Nadel, is that a cognitive map is a powerful memory of landmarks which allows novel short-cutting to occur. The other, sensu Gallistel, is that a cognitive map is any representation of space held by an animal. Other definitions with quite different meanings are also summarised. I argue that no animal has been conclusively shown to have a cognitive map, sensu Tolman, O'Keefe and Nadel, because simpler explanations of the crucial novel short-cutting results are invariably possible. Owing to the repeated inability of experimenters to eliminate these simpler explanations over at least 15 years, and the confusion caused by the numerous contradictory definitions of a cognitive map. I argue that the cognitive map is no longer a useful hypothesis for elucidating the spatial behaviour of animals and that use of the term should be avoided.

Bystander behaviour as an influence on bullying in high schools

In response to evidence that bullying in schools persists in the presence of bystanders, this study sought to add to the existing knowledge about its reinforcing effects. The objectives of this research project were to investigate non-intervention in bullying incidents by students. Unique approaches of this research are the multi-dimensional investigation of the emotional, cognitive and behavioural factors from the bystander's perspective, within the context of a co-educational Catholic high school, in a sample of eighteen Year 8 students. In-depth and group interviews, participant observation and the input of a focus group of teachers formed the data collection. Previous findings that fear prevents bystanders from taking action, were extended by this study which revealed was that there are several sources of this fear. The study found reasons for students' fear included embarrassment at making a mistake, the importance of the teachers' responses, the need to assimilate into the new school culture, to be 'cool' and to avoid a negative, conforming self-image. Importantly, the existing focus on fear does not explain why students do not anonymously report bullying. This study found that students resisted taking responsibility for intervening, and unexpected findings included that students categorised victims, only caring enough to report bullying if the victim were a friend or sibling; and also that the thrill of watching bullying was a strong deterrent to bystander intervention. The study suggests, therefore, information based anti-bullying policies will be ineffective unless students are motivated to intervene. It is crucial that programmes now address the emotional deterrents of fear, excitement and apathy before considering educational approaches, and that future policies need to examine the culture of the school, including teachers' responses to bullying, which dictates the behavioural code for incoming Year 8 students.

Life events and cognitive processing in sexually dysfunctional individuals

The aim of this study was to make an assessment of the role of the cognitive component in the development of sexual dysfunction. Past studies have largely focused on the impact of particular events on sexual dysfunction and have not assessed the role of the perception of these events. A number of theories on sexual dysfunction have been developed to explain the influence of cognitions, but these have not been empirically tested. This study investigated the role of the cognitive evaluation of sexual experiences among 30 sexually dysfunctional participants and 30 control participants who were matched on age, marital status and biological sex. The Cognitive Aspects of Sexual Dysfunction Measure (CASDM) was constructed to evaluate sexual dysfunction. This measure was designed to tap into the major events in participants’ lives and, more importantly, the participants’ perceptions of these events. The components assessed were the intergenerational (family of origin), individual, current life and relationship aspects of the person’s life. These factors were measured from the responses to questions regarding the participant's cognitions about past experiences, the effect of the past experience on the participant at the lime it occurred and the influence this experience had on the participant's sense of self now, their relationship now and sexual functioning now. The main findings in the intergenerational area were that past experiences were perceived by the sexually dysfunctional group to be having an impact on the self, relationships and their sexual functioning although there were no actual differences between the sexually functional and the sexual dysfunctional participants in the occurrence of the event. For the individual factors, there were differences between the sexually functional and sexually dysfunctional participants in both values and lifestyle, although these were not perceived to be having an impact on the self, relationship and sexual functioning. In the relationship area, anger was the major factor separating the sexually functional and sexually dysfunctional groups. Anger was high among the sexually dysfunctional participants and was perceived to be having an impact on self, the couple’s relationship and their sexual functioning. The importance of all these variables in providing a better understanding of the cognitive factors in sexual dysfunction was discussed. The findings demonstrate the importance of cognitions in influencing sexual functioning. Clinicians should not simply deal with the life experiences of sexually dysfunctional people when attempting to change their behaviour, but should focus on changing cognitions about the behaviours in relation to sexual functioning.
