Similarity as transformation

We propose that similarity is determined by the transformation distance between representations: entities which are perceived to be similar have representations which are readily transformed into one another, whereas transforming between dissimilar entities requires many transformations. We present three experiments that indicate that similarity is strongly influenced by transformation distance. These data present a challenge for featural or spatial accounts of similarity. Finally, we introduce a family of transformation-based accounts of similarity, called 'Representational Distortion', as a specific example of a transformational approach to similarity.     

Child protection investigations: Discourse analysis and the management of incommensurability

This paper asks whether discourse analytic approaches in social psychology have yet produced methodologies adequate to the investigation of institutional ‘gaze’. Institutional language has been explored to the extent that state agencies construct members of the public by speaking about them in particular ways. This has often provided insight into the co-existence and competition of incommensurable discourses. However, studies of representation in the sense of speaking for have been notably absent from social psychology. It is argued that this aspect of discourse is a vital component in the study of contemporary governmental multi-agency strategy in the area of child protection, where recent legislation and policy aims at the coordination of incommensurable discourses. A methodology for studying this strategy is outlined through an account of the actor network approach in science studies, accounts of the State under the post-modern condition, and analyses of sections of interviews with social workers.     

The Rational Analysis Of Mind And Behavior

Rational analysis (Anderson 1990, 1991a) is an empiricalprogram of attempting to explain why the cognitive system isadaptive, with respect to its goals and the structure of itsenvironment. We argue that rational analysis has two importantimplications for philosophical debate concerning rationality. First,rational analysis provides a model for the relationship betweenformal principles of rationality (such as probability or decisiontheory) and everyday rationality, in the sense of successfulthought and action in daily life. Second, applying the program ofrational analysis to research on human reasoning leads to a radicalreinterpretation of empirical results which are typically viewed asdemonstrating human irrationality.     

Why are unemployed aged fifty and over less likely to find a job? A decomposition analysis

Reemployment chances for unemployed aged fifty and over are low compared to those of younger persons. To explain the different chances, the job search literature has largely focused on the job search behavior of unemployed individuals. Based on job search models, we propose that not only job search behavior, but also wage setting behavior, attitudinal variables and personal variables impact the difference in reemployment opportunities. Besides gaining insight into which variables explain the difference in reemployment opportunities, we also test how much of the difference each of these variables explains. We do this by drawing on a decomposition analysis. Using data from 647 recently unemployed, we find that about one third of the reemployment gap can be explained by the variables suggested by job search models, mostly in terms of age differences in search behavior, educational levels and reservation wage. Hence, about 70 % can be ascribed to other factors, such as employer preferences for those aged between 18 and 49. Implications of these results for theory, policy and practice are discussed.     

Daydreams and Anarchy: A Defense of Anomalous Mental Causation

Must mental properties figure in psychological causal laws if they are causally efficacious? And do those psychological causal laws give the essence of mental properties? Contrary to the prevailing consensus, I argue that, on the usual conception of laws that is in play in these debates, there are in fact lawless causally efficacious properties both in and out of the philosophy of mind. I argue that this makes a great difference to the philosophical relevance of empirical psychology. 1 begin by making the case that revolutions and hurricanes are lawless phenomena, before arguing for a similar thesis about creativity, love, courage, dreams, daydreams, and musings. Furthermore, the empirical research on these phenomena suggests that the philosophical issues may be independent of what empirical psychology can tell us.     

Thirsty for H2O? Multiple essences and psychological essentialism

Within psychology, essentialism has often been understood as the imputation of a hidden natural underpinning that determines the identity and membership of a given category. This naturalistic understanding has failed to address the varied and multi-faceted manner in which essentialist beliefs function on a cognitive level. Specifically, such an understanding does not account for essentialist beliefs that are related to functional categories derivative of a particular individual's present needs or social context. A parsimonious theory of psychological essentialism that accounts for beliefs in essences with respect to all categories, including those believed to be “natural”, is found in the writing of James (The Principles of Psychology, Vol. 2, Dover, New York, NY, 1890/1950). After accounting for the manner in which James’ theory addresses the limitations of the naturalistic view and extends it, it is recommended that his theory be incorporated into future empirical study of psychological essentialism.     

Taxometric analysis supports a dimensional latent structure for schizotypy

The existence of a discrete class of people vulnerable to schizophrenia spectrum disorders is the most replicated finding of taxometric research. Evidence for such a “taxon” has been obtained with diverse measures of schizotypy in clinical, high-risk, and normal samples. However, recent demonstrations that skewed indicators of a latent dimension can yield a spuriously taxonic pattern of results may call some of these findings into question. Normal adults (N = 1073) completed measures of positive (perceptual aberration, magical ideation) and negative (physical and social anhedonia) components of schizotypy. Taxometric curves resembled those obtained previously, but when a simulation procedure took skew into account, dimensional models of schizotypy received stronger support than taxonic models for most schizotypy components, with findings for magical thinking inconclusive. A re-evaluation of previous taxonic conclusions regarding the latent structure of schizotypy is indicated.     

Trans employees,transitioning, and job satisfaction

While trans employees have become more widely recognized in society, our understanding of their work experiences remains underdeveloped. In the current study, we investigate whether transitioning is associated with job satisfaction in England, Wales and Scotland. Using longitudinal data collected before and after sex reassignment surgery associations between job satisfaction and mental health/life satisfaction are examined for trans men and women. The estimations suggest that employees experience higher job satisfaction, mental health and life satisfaction after sex reassignment surgery than before. In addition, the estimations suggest that after sex reassignment surgery, the associations between job satisfaction and mental health/life satisfaction are stronger than before. Moreover, the estimations suggest that employees not only experience higher job satisfaction after sex reassignment surgery, but also during transitioning. The results suggest that, firms should not treat transitioning employees in a biased way, since their transition might entail positive personal and workplace advancements.
