Refocussing therapy : the effectiveness and uniqueness of a God-based therapy method : a thesis presented in partial fulfilment of the requirements for the degree of Master of Arts in Psychology at Massey University, Albany, New Zealand

Refocussing Therapy (RFT) is a God-based theory and psychotherapy approach. The aim of the present study was to evaluate the effectiveness and uniqueness of RFT using a quasi-experimental mode of investigation. Over a period of four months pre- and post-treatment assessments of 49 RFT clients' mental health status and religious coping were made using the TOP v 4.1 and RCOPE measures. Changes were also assessed for a comparison group of 10 pastoral care (PC) recipients. Significant positive treatment gains were reported by RFT clients, while PC recipients had smaller but generally positive treatment gains. Positive religious coping improved for both the RFT group and the PC group. However, negative religious coping reduced significantly for the RFT group but increased for the PC group. Findings offer preliminary support for the effectiveness of RFT. and indicate that RFT impacts significantly upon clients' clinical status and religious coping. Further research is recommended to determine the efficacy of RFT

Objective probability and quantum fuzziness

This paper offers a critique of the Bayesian interpretation of quantum mechanics with particular focus on a paper by Caves, Fuchs, and Schack containing a critique of the "objective preparations view" or OPV. It also aims to carry the discussion beyond the hardened positions of Bayesians and proponents of the OPV. Several claims made by Caves et al. are rebutted, including the claim that different pure states may legitimately be assigned to the same system at the same time, and the claim that the quantum nature of a preparation device cannot legitimately be ignored. Both Bayesians and proponents of the OPV regard the time dependence of a quantum state as the continuous dependence on time of an evolving state of some kind. This leads to a false dilemma: quantum states are either objective states of nature or subjective states of belief. In reality they are neither. The present paper views the aforesaid dependence as a dependence on the time of the measurement to whose possible outcomes the quantum state serves to assign probabilities. This makes it possible to recognize the full implications of the only testable feature of the theory, viz., the probabilities it assigns to measurement outcomes...Comment: 21 pages, no graphics, inspired by "Subjective probability and quantum certainty" (quant-ph/0608190 v2

Can we program or train robots to be good?

As robots are deployed in a widening range of situations, it is necessary to develop a clearer position about whether or not they can be trusted to make good moral decisions. In this paper, we take a realistic look at recent attempts to program and to train robots to develop some form of moral competence. Examples of implemented robot behaviours that have been described as 'ethical', or 'minimally ethical' are considered, although they are found to operate only in quite constrained and limited application domains. There is a general recognition that current robots cannot be described as full moral agents, but it is less clear whether will always be the case. Concerns are raised about the insufficiently justified use of terms such as 'moral' and 'ethical' to describe the behaviours of robots that are often more related to safety considerations than to moral ones. Given the current state of the art, two possible responses are identified. The first involves continued efforts to develop robots that are capable of ethical behaviour. The second is to argue against, and to attempt to avoid, placing robots in situations that demand moral competence and an understanding of the surrounding social situation. There is something to be gained from both responses, but it is argued here that the second is the more responsible choice

Robots and human dignity: A consideration of the effects of robot care on the dignity of older people

This paper explores the relationship between dignity and robot care for older people. It highlights the disquiet that is often expressed about failures to maintain the dignity of vulnerable older people, but points out some of the contradictory uses of the word 'dignity'. Certain authors have resolved these contradictions by identifying different senses of dignity; contrasting the inviolable dignity inherent in human life to other forms of dignity which can be present to varying degrees. The capability approach (CA) is introduced as a different but tangible account of what it means to live a life worthy of human dignity. It is used here as a framework for the assessment of the possible effects of eldercare robots on human dignity. The CA enables the identification of circumstances in which robots could enhance dignity by expanding the set of capabilities that are accessible to frail older people. At the same time, it is also possible within its framework to identify ways in which robots could have a negative impact, by impeding the access of older people to essential capabilities. It is concluded that the CA has some advantages over other accounts of dignity, but that further work and empirical study is needed in order to adapt it to the particular circumstances and concerns of those in the latter part of their lives

Estimation of distances in virtual environments using size constancy

It is reported in the literature that distances from the observer are underestimated more in virtual environments (VEs) than in physical world conditions. On the other hand estimation of size in VEs is quite accurate and follows a size-constancy law when rich cues are present. This study investigates how estimation of distance in a CAVETM environment is affected by poor and rich cue conditions, subject experience, and environmental learning when the position of the objects is estimated using an experimental paradigm that exploits size constancy. A group of 18 healthy participants was asked to move a virtual sphere controlled using the wand joystick to the position where they thought a previously-displayed virtual cube (stimulus) had appeared. Real-size physical models of the virtual objects were also presented to the participants as a reference of real physical distance during the trials. An accurate estimation of distance implied that the participants assessed the relative size of sphere and cube correctly. The cube appeared at depths between 0.6 m and 3 m, measured along the depth direction of the CAVE. The task was carried out in two environments: a poor cue one with limited background cues, and a rich cue one with textured background surfaces. It was found that distances were underestimated in both poor and rich cue conditions, with greater underestimation in the poor cue environment. The analysis also indicated that factors such as subject experience and environmental learning were not influential. However, least square fitting of Stevens’ power law indicated a high degree of accuracy during the estimation of object locations. This accuracy was higher than in other studies which were not based on a size-estimation paradigm. Thus as indirect result, this study appears to show that accuracy when estimating egocentric distances may be increased using an experimental method that provides information on the relative size of the objects used

Forging consensus: an integrated view of how categories shape the perception of organizational identity

This paper integrates two approaches – the “categorization as a theoretical tool” and the “typicality judgment” – which both emphasize audience confusion as a mechanism through which category spanners become devalued or ignored. However, the two perspectives differ in their specification of why confusion will likely lead to devaluation or ignoring. In this study, we consider the interplay of these two approaches in the setting of corporate law market. We find that spanning product categories has a U-shaped relationship with perceived clarity of law firm identity. While none of the two perspectives alone can explain our findings, they can do so together

Autonomic physiological data associated with simulator discomfort

The development of a physiological monitoring capability for the Army's advanced helicopter simulator facility is reported. Additionally, preliminary physiological data is presented. Our objective was to demonstrate the sensitivity of physiological measures in this simulator to self-reported simulator sickness. The data suggested that heart period, hypergastria, and skin conductance level were more sensitive to simulator sickness than were vagal tone and normal electrogastric activity

We need to talk about deception in social robotics!

Although some authors claim that deception requires intention, we argue that there can be deception in social robotics, whether or not it is intended. By focusing on the deceived rather than the deceiver, we propose that false beliefs can be created in the absence of intention. Supporting evidence is found in both human and animal examples. Instead of assuming that deception is wrong only when carried out to benefit the deceiver, we propose that deception in social robotics is wrong when it leads to harmful impacts on individuals and society. The appearance and behaviour of a robot can lead to an overestimation of its functionality or to an illusion of sentience or cognition that can promote misplaced trust and inappropriate uses such as care and companionship of the vulnerable. We consider the allocation of responsibility for harmful deception. Finally, we make the suggestion that harmful impacts could be prevented by legislation, and by the development of an assessment framework for sensitive robot applications
