D. Z. Phillips and Wittgenstein's On Certainty

I start from Phillips' discussion of Rhees's dissatisfaction with the idea of a language‐game. Then, from a rereading of Moore, I go on to exemplify interconnected uses of the expressions “language‐game,”“recurrent procedure,”“world‐picture,”“formal procedure,”“agreement in judgment,”“genre picture” and “form of life.” The discussion is related to sense perception, our knowledge of time and space, and the picture‐theory. These topics connect with Wittgenstein's earlier treatment of the will – which changed markedly later. The subtext (in footnotes) confronts (i) the sceptical methods of Descartes and Hume with the grammatical methods of Leibniz, Kant and Wittgenstein, and (ii) the realism of Leibniz and the Tractatus with the transcendental idealism of Kant. My conclusion is that, although the method of Wittgenstein's later work remains in a sense grammatical, (i) in its new form it can free us from the conviction that the intellect can and must resolve one way or the other the conflicts that arise in the course of the latter confrontation, and that (ii), although release from such a conviction is to be seen as the aim of philosophical discourse in general, it allows philosophy to retain its overriding significance. A positive element in that lies in the respect the method demands for that in a human life which is transcendental to the activity of scientific theorising: respect, therefore, for the unique perspective of the individual historical agent.     

Biased Assimilation and Attitude Polarization in Response to Learning About Biological Explanations of Homosexuality

According to attribution theory stigmatized behaviors with biological explanations will be perceived more positively than those with psychological explanations, but informing people of the biological explanations of homosexuality has produced mixed results on attitudes. To examine if biased processing could explain previous findings we tested whether biased assimilation (initial attitudes’ effect on perceived persuasiveness) and attitude polarization (initial attitudes’ effect on reported attitude change) affected learning about biological explanations of homosexuality among 210 U.S. undergraduates. General Linear Model analyses showed that (1) individuals with positive attitudes toward homosexuality saw biological explanations as a more persuasive reason to accept homosexuality than those with negative attitudes, and (2) initial attitudes generally led to a strengthening of those attitudes after learning about biological explanations.     

What Lies Outside Language?

The paper aims to make out the incoherence of the distinction between and rigid separation of 'the linguistic' and 'the extra-linguistic' as well as to absolve Wittgenstein from any commitment to it. Insistence on a descent from the abstract to a concrete discussion allows a connection to be made between Tractatus positions such as: 'The limits of my language indicate the limits of my world.' and 'The world and life are one.' and the Investigations : 'What has to be accepted is - so one could say - forms of life .' From this a picture is developed of the intimate interconnection between language, practical life, and world.     

Why do High IQ Societies Differ in Intellectual Achievement? The Role of Schizophrenia and Left-Handedness in Per Capita Scientific Publications and Nobel Prizes

Previous research has attempted to understand why countries with relatively favorable conditions and high estimated average IQs (such as Finland and Japan) have a relatively low per capita number of scientific Nobel prizes. In the present study, we examine whether there is a relationship between national schizophrenia and left-handedness prevalence, on the one hand, and per capita scientific and literary achievement, on the other hand, in countries with IQ estimates of at least 90. We found that per capita science and literature Nobel prizes and scientific publications are strongly negatively associated with schizophrenia and strongly positively correlated with left-handedness. There also was a very pronounced negative correlation between schizophrenia rate and left-handedness rate. These results suggest that genius can be regarded as a combination of very high IQ, aspects of high-functioning autism (specifically low empathy) plus relatively low impulse control, consistent with observations of intellectually outstanding individuals, and the fact that schizophrenia appears to constitute the opposite pole of these aspects of autism spectrum. We posit differences in androgen levels as a possible underlying explanation for these findings.     

Barriers and Facilitators to Implementing Attachment-based Family Therapy into a Child Welfare Setting: A Qualitative Process Evaluation

Child welfare systems (CWSs) worldwide show increased interest in adopting empirically informed clinical strategies to increase treatment effectiveness. Many empirically supported treatments (ESTs) exist, but little is known about EST implementation barriers and facilitators in CWS. This study explored CWS providers’ experiences of implementing attachment-based family therapy (ABFT) in home-based services of the Flemish CWS (in Belgium). Sixteen CWS providers (twelve counselors and four supervisors) involved in three home-based services were interviewed. The Consolidated Framework for Implementation Research (CFIR) was used to guide collection, coding, and analysis of interview data. Findings revealed that implementation success was related to ABFT's fit with the CWS's mission, philosophy, and existing practices. CWS providers’ belief in the compatibility between ABFT and CWS increased investment in implementation efforts and persistence to overcome challenges and setbacks. Some barriers pertained to the learning of ABFT and some barriers pertained to systems level challenges such as lack of leadership and support, poor coordination with referral sources and other youth care partners, and lack of policy support. For successful expansion of ESTs into CWS settings, various barriers at multiple systemic levels need to be addressed.     

Knowledge Based Solution Strategies in Medical Reasoning

The techniques of propositionol analysis are used to examine the protocols of seven cardiologists in a task involving the diagnosis of a case of acute bacterial endocarditis and an explanation of its underlying pathophysiology. It is shown that the explanations of physicians making an accurate diagnosis can be accounted for in terms of a model consisting of pure forward reasoning through a network of causal rules, actuated by relevant propositions embedded in the stimulus text. These rules appear to derive from the physician's underlying knowledge base rather than any information in the text itself. In contrast, subjects with inacurate diagnoses tend to make use of a mixture of forward and backward reasoning, beginning with a high level hypothesis and proceeding in a top-down fashion to the propositions embedded in stimulus text, or to the generation of irrelevant rules.     

Perceptions of self-oriented and other-oriented “everyday” helpers

In two investigations, participants were asked to evaluate eight different young adults (Study 1) and children (Study 2) who had described (a) a situation in which they had offered assistance to another individual and (b) the reason why they had offered the assistance in that situation. Although other-oriented helpers and their motives were generally rated more favorably than self-oriented helpers and their motives, participants' evaluations were found to be influenced by the closeness of the helper-recipient relationship, the type of help provided (i.e., instrumental vs. expressive), and the participants' gender. A similar pattern of responses was found for the undergraduate (Studies 1 and 2) and preadolescent (Study 2) participants.
