Functional explanation and the function of explanation

Teleological explanations (TEs) account for the existence or properties of an entity in terms of a function: we have hearts because they pump blood, and telephones for communication. While many teleological explanations seem appropriate, others are clearly not warranted--for example, that rain exists for plants to grow. Five experiments explore the theoretical commitments that underlie teleological explanations. With the analysis of [Wright, L. (1976). Teleological Explanations. Berkeley, CA: University of California Press] from philosophy as a point of departure, we examine in Experiment 1 whether teleological explanations are interpreted causally, and confirm that TEs are only accepted when the function invoked in the explanation played a causal role in bringing about what is being explained. However, we also find that playing a causal role is not sufficient for all participants to accept TEs. Experiment 2 shows that this is not because participants fail to appreciate the causal structure of the scenarios used as stimuli. In Experiments 3-5 we show that the additional requirement for TE acceptance is that the process by which the function played a causal role must be general in the sense of conforming to a predictable pattern. These findings motivate a proposal, Explanation for Export, which suggests that a psychological function of explanation is to highlight information likely to subserve future prediction and intervention. We relate our proposal to normative accounts of explanation from philosophy of science, as well as to claims from psychology and artificial intelligence.     

Conceptions of career choice and attainment: Developmental levels in how children think about careers

Children’s Conceptions of career choice and attainment were evaluated in two studies to test whether reasoning levels varied by grade level (Studies 1 and 2) and perspective-taking complexity (Study 2). Results indicated that younger children (Grade K) were more likely to use reasoning strategies associated with fantasy and magical thinking and older children (Grade 6) were more likely to consider personal interests, abilities, and job requirements. Study 2 replicated these results and also found that children evaluated as able to use more complex perspective-taking reported higher reasoning levels when discussing their Conceptions of career choice and attainment.     

employers' perceptions of transition programming for students with emotional disturbances

This qualitative study compiled input from employers (N = 7) participating in a program geared to prepare high school students with emotional disturbances for post‐high‐school employment situations. Data were collected through open‐ended interviews related to 4 research questions and analyzed through thematic and comparative analysis. Results showed a link between the skills employers desired from their employees and skills needed for students with emotional disturbances to be successful. Employers' recommendations included measures to address prior to program implementation and ways to create strong support systems for students with disabilities.     

Health Care Chaplains and their Role on Institutional Ethics Committees: An Australia Study

This paper presents the results of the largest Australian pastoral study concerning the perceptions of health care chaplains about their involvement on hospital research ethics committees (also known in some contexts as institutional ethics committees). Survey results from over 300 Australian health care chaplains indicated that nearly 90% of chaplains believed there was merit in chaplains serving on hospital research ethics committees, yet only a minority (22.7%) had ever participated on such committees. Data from in-depth interviews is also presented exploring the reasons for the lack of participation and the varying opinions regarding the role, appropriateness, and value of chaplains on ethics committees. Some implications of this study with respect to chaplaincy, hospital research ethics committees, health care institutions, ecclesiastical institutions, and government responsibilities are discussed.     

Violent Delinquency: An Examination of Psychopathic Typologies

This study sought to determine the combined effects of psychopathy, low intellectual functioning, and love deprivation on violent delinquency. Low-intellectual-functioning psychopaths were significantly more violent than were low or high-intellectual-functioning nonpsychopaths or high-intellectual-functioning psychopaths. Love deprivation was more strongly related to violence than was psychopathy/intellectual functioning, and severely love-deprived, low-intellectual-functioning psychopaths were the most violent.     

The FAD–Plus: Measuring Lay Beliefs Regarding Free Will and Related Constructs

We describe the development of FAD–Plus, a 27-item measure of lay beliefs in free will and 3 closely related constructs: scientific determinism, fatalistic determinism, and unpredictability. Previously published measures included only a subset of these variables and tended to assume an a priori pattern of relations among these 4 beliefs. In Study 1, exploratory factor analyses suggested relatively independent factors. This independence was sustained in Study 2, using a confirmatory analysis. Each of the 4 subscales (Free Will, Scientific Determinism, Fatalistic Determinism, and Unpredictability) showed acceptable internal consistencies. Study 2 also mapped out associations with the Big Five personality traits and showed that believing in free will is not synonymous with having an internal locus of control. Study 3 replicated the instrument's structure and subscale reliabilities in a community sample. Preliminary applications are described.     

Executive functions and social skills in survivors of pediatric brain tumor

Medical advances have resulted in increased survival rates for children with brain tumors. Consequently, issues related to survivorship have become more critical. The use of multimodal treatment, in particular cranial radiation therapy, has been associated with subsequent cognitive decline. Specifically, deficits in executive functions have been reported in survivors of various types of pediatric brain tumor. Survivors are left with difficulties, particularly in self-monitoring, initiation, inhibition, and planning, to name a few. Another domain in which survivors of pediatric brain tumor have been reported to show difficulty is that of social skills. Parents, teachers, and survivors themselves have reported decreased social functioning following treatment. Deficits in executive functions and social skills are likely interrelated in this population, as executive skills are needed to navigate various aspects of social interaction; however, this has yet to be studied empirically. Twenty-four survivors of pediatric brain tumor were assessed using a computerized task of executive functions, as well as paper-and-pencil measures of social skills and real-world executive skills. Social functioning was related to a specific aspect of executive functions, that is, the survivors' variability in response time, such that inconsistent responding was associated with better parent-reported and survivor-reported social skills, independent of intellectual abilities. Additionally, parent-reported real-world global executive abilities predicted parent-reported social skills. The implications of these findings for social skills interventions and future research are discussed.     

To know or not to know: an application of Bion’s K and –K to child treatment1

The authors discuss an application of Bion’s conceptualisation of thinking and non-thinking states (K and –K links) to the treatment of a nine-year-old girl. The authors consider Bion’s interrelated concepts such as K and –K, container/contained, maternal reverie, and the development of thinking through alpha function to be highly applicable to child treatment. The afore-mentioned conceptual elements are used to elucidate case material over two consecutive hours. A K link is established between therapist and patient, the fragility of which link is then demonstrated by its deterioration into a –K link. Complex issues about knowing and not knowing are central in this girl’s clinical presentation. She was conceived through in vitro fertilisation (IVF), and subsequently diagnosed with cerebral palsy. The authors consider the emotional impact of this origin story and how the parents relate to it. The authors discuss how parents sometimes cope with perceived losses by wishing to shield or protect their children. This can have repercussions for children’s efforts to know (K) and not to know (?K). The fear that emotional knowledge will be too painful to bear can interfere with ‘learning from experience’. Bion’s premise that the purpose of analysis is the growth of the mind is synonymous with the child analyst’s goal of fostering development and understanding impediments to development.
