A Moderate Defence of the Use of Thought Experiments in Applied Ethics

Thought experiments have played a pivotal role in many debates within ethics—and in particular within applied ethics—over the past 30 years. Nonetheless, despite their having become a commonly used philosophical tool, there is something odd about the extensive reliance upon thought experiments in areas of philosophy, such as applied ethics, that are so obviously oriented towards practical life. Herein I provide a moderate defence of their use in applied philosophy against those three objections. I do not defend all possible uses of thought experiments but suggest that we should distinguish between legitimate and illegitimate uses. Their legitimate uses are determined not so much by the modal content of any actual thought experiment itself, but by the extent to which the argument in which it is nested follows basic tenets of informal logic and respects the fundamental contingency of applied ethical problems. In pursuing these ideas, I do not so much provide a set of criteria for their legitimate use, but more modestly present two significant ways in which their use can go awry.     

Effects of action planning and coping planning within the theory of planned behaviour: A physical activity study of patients undergoing haemodialysis

Objective

Patients on dialysis have low physical activity levels. The aim of the study was to examine the validity of action planning and coping planning within the theory of planned behaviour framework, for predicting physical activity behaviour of patients on haemodialysis.

Design

This is a prospective study design.

Methods

One hundred and forty-four patients who were undergoing haemodialysis were selected from dialysis centres. The mean age of the patients was 56.61 (SD = 11.38) years. The patients completed a questionnaire including variables from the theory of planned behaviour, action planning and coping planning. Physical activity was prospectively assessed at 4-weeks with the validated International Physical Activity Questionnaire self-report measure. A hierarchical regression analysis was performed to examine the effects of action planning and coping planning on physical activity behaviour.

Results

There was a main effect for coping planning but not for action planning. Moreover, the analyses resulted in a significant amount of incremental variance accounted for by the interaction of coping planning and intention.

Conclusion

Results suggest the combination of high levels of coping planning and intention is associated with increases in physical activity.     

Potential Effects of Faking on the NEO-PI-R: Willingness and Ability to Fake Changes Who Gets Hired in Simulated Selection Decisions

The impact of response distortion (faking) on selection decisions was investigated. Participants (N = 224) completed the NEO-PI-R under instructions to “make the most favorable impression” and/or “answer honestly.” Those instructed to fake were often over-represented at the top of the score distributions as instructions to fake resulted in higher scores both between and within groups in a test–retest situation. There was significantly lower correspondence between participants’ honest scores and their faked scores as well as multiple instances where participants with unfavorable honest scores subsequently produced the most favorable scores when faking. Response distortion may remain a serious threat to the use of personality test scores in selection.

Exploring Genetic Counseling Communication Patterns: The Role of Teaching and Counseling Approaches

The educational and counseling models are often touted as the two primary professional approaches to genetic counseling practice. Yet, research has not been conducted to examine how these approaches are used in practice. In the present study, we conducted quantitative communication analyses of BRCA1 genetic counseling sessions. We measured communication variables that represent content (e.g., a biomedical focus) and process (e.g., passive listening) to explore whether genetic counselor approaches are consistent with prevailing professional models. The Roter Interaction Analysis System (RIAS) was used to code 167 pre-test genetic counseling sessions of members of a large kindred with an identified BRCA1 mutation. Three experienced genetic counselors conducted the sessions. Creating composite categories from the RIAS codes, we found the sessions to be largely educational in nature with the counselors and clients devoting the majority of their dialogue to providing biomedical information (62 and 40%, respectively). We used cluster analytic techniques, entering the composite communication variables and identified four patterns of session communication: Client-focused psychosocial, biomedical question and answer, counselor-driven psychosocial, and client-focused biomedical. Moreover, we found that the counselors had unique styles in which they combined the use of education and counseling approaches. We discuss the importance of understanding the variation in counselor communication to advance the field and expand prevailing assumptions.     

Objects capture perceived gaze direction

The interpretation of another person's eye gaze is a key element of social cognition. Previous research has established that this ability develops early in life and is influenced by the person's head orientation, as well as local features of the person's eyes. Here we show that the presence of objects in the attended space also has an impact on gaze interpretation. Eleven normal adults identified the fixation points of photographed faces with a mouse cursor. Their responses were systematically biased toward the locations of nearby objects. This capture of perceived gaze direction probably reflects the attribution of intentionality and has methodological implications for research on gaze perception.     

Creativity, intelligence, and personality: a critical review of the scattered literature

The authors examined the relations among intelligence, personality, and creativity. They consider the concept and definition of creativity in conjunction with the qualifications that researchers in the field have suggested. The present authors briefly refer to historiometric studies but focus on psychometric intelligence and its relations to tests of divergent thinking (DT) and ratings of creativity. The authors consider the relation between personality and creativity in the context of Eysenckian 3-factor and 5-factor models of personality and with reference to DT tests and ratings of creativity. The authors also present recommendations for the future study of creativity.     

The leg-to-body ratio as a human aesthetic criterion

There are surprisingly few empirical studies on the aesthetic appeal of human legs, examining such variables as length or shape. The human legs are conspicuous in erotic contexts, but few studies have experimentally tested preferences for longer legs. This study examined the utility of the human leg-to-body ratio (LBR) as a specific aesthetic criterion among 71 British undergraduates. Participants rated for physical attractiveness line drawings that varied in five levels of LBR. The results showed that a longer LBR was preferred as maximally attractive in women, whereas a shorter LBR was preferred in men. Evolutionary psychological and socio-cultural explanations for this aesthetic preference are discussed, and the study's limitations are considered.     

Self-estimates of intelligence: a study in two African countries

Black and White South Africans (n = 181) and Nigerians (n = 135) completed a questionnaire concerning the estimations of their own and their relatives' (father, mother, sister, brother) multiple intelligences as well as beliefs about the IQ concept. In contrast to previous results (A. Furnham, 2001), there were few gender differences in self-estimates. In a comparison of Black and White South Africans, it was clear the Whites gave higher estimates for self, parents, and brothers. However, overall IQ estimates for self and all relatives hovered around the mean of 100. When Black South Africans and Nigerians were compared, there were both gender and nationality differences on the self-estimates with men giving higher self-estimates than women and Nigerians higher self-estimates than South Africans. There were also gender and nationality differences in the answers to questions about IQ. The authors discuss possible reasons for the relatively few gender differences in this study compared with other studies as well as possible reasons for the cross-cultural difference.     

Performing the vertical jump: movement adaptations for submaximal jumping

The purpose of this study was to gain insight into the kinematics and kinetics of the vertical jump when jumping for different heights and to investigate movement effectiveness as a criterion for movement control in submaximal jumping. In order to jump high a countermovement is used and large body segments are rotated, both of which consume energy which is not directly used to gain extra jump height. It was hypothesized that the energy used to reach a specified jump height is minimized by limiting the non-effective energy consumed. Standing vertical jumps attempting 100%, 75%, 50%, and 25% of maximal height were performed by a group of 10 subjects. Force and motion data were recorded simultaneously during each performance. We found that jump height increased due to increasing vertical velocity at take off. This was primarily related to an increase in countermovement amplitude. As such, flexion amplitude of the hip joint increased with jump height whereas the ankle and knee joint flexion did not. These findings revealed that for submaximal jumping a consistent strategy was used of maximizing the contribution of distal joints and minimizing the contribution of proximal joints. Taking into account the high inertia of proximal segments, the potential energy deficit due to countermovement prior to joint extension, the advantageous horizontal orientation of the foot segment during stance and the tendon lengths in distal muscles, it was concluded that movement effectiveness is a likely candidate for the driving criterion of this strategy.     

African parents’ estimates of their own and their children’s multiple intelligences

A total of 421 parents from four Southern African countries (Nambia, South Africa, Zambia, and Zimbabwe) estimated their own and their children’s multiple intelligences. There were consistent country and sex differences in self-estimates. Nambians tended to give lowest self-estimates and Zambians highest self-estimates. Contrary to previous findings from other continents females gave higher self-estimates than males on all seven multiple intelligences. These results were mirrored in the estimation of children: females gave higher scores than males and Zambians gave highest estimates and Nambians lowest. Reasons for these findings are discussed.
