The Assessment of Limb Apraxia: An Investigation of Task Effects and Their Cause

To test the effects of variations in the structure of tasks used to assess limb apraxia, eight tasks—differing in their modes of elicitation (tactile, verbal, visual, imitation) and/or types of movement elicited (transitive, intransitive, meaningless)—were administered to 25 carefully selected subjects with idiomotor limb apraxia. When standardized scores (based on the performance of 10 nonneurologically impaired control subjects) were used to measure the differences between tasks, no clinically significant task effects were found. Additional investigation was made of two causal hypotheses regarding the processes underlying limb apractic performance. The results of factor analyses and a search for double dissociations among individual subjects were consistent with the (severity) hypothesis that differences in task performances (raw scores) reflect degrees of task difficulty; and they failed to support the (disconnection) hypothesis that posits separate and independent neural/mental processes underlying task performances.     

The Efficient Assessment of Self-Esteem: Proposing the Brief Rosenberg Self-Esteem Scale

Self-esteem is defined as sense of self-worth and self-respect, being crucial for understanding people’s well-being and success. It is one of the most studied constructs in the social sciences, with the Rosenberg Self-Esteem Scale (RSES) being the most used measure. Across four studies (N = 1450), we tested the psychometric parameters of an abbreviated version of the RSES. Through Item Response Theory, the five best items were selected to form the unidimensional Brief Rosenberg Self-Esteem Scale (B-RSES), a reliable and valid measure of self-esteem, which is invariant across age groups and gender. In addition, both RSES and B-RSES correlated very similarly with the Big Five Personality Factors. Also, the B-RSES was strongly correlated with three other short measures of self-esteem, besides being more strongly associated with a range of variables such as conscientiousness and self-competence in comparison to the other three short scales. Together, the B-RSES is especially useful in research that requires rapid evaluation and the use of multiple variables.

     

Ethnomethodological and Hermeneutic-Phenomenological Perspectives on Scientific Practices

The paper presents a comparative analysis between hermeneutics and ethnomethodology of science. A careful examination of the approaches suggested by the two programs not only demonstrates that a non-essentialist inquiry of scientific practices is possible, it also reveals how the significant methodological differences between these (post-phenomenological) programs inform divergent pictures of science’s practical rationality. The role these programs play in the debates on science’s cognitive autonomy is illuminated by spelling out the idea of the internal criticism of scientific research they advance. In contrast to the external criticism of social epistemologists, the internal one does not aim at a deconstruction of science’s cognitive autonomy. Its task is to promote the epistemic emancipation of scientific communities by stressing the reflexive dimension of scientific research.     

Rhetoric and Double Hermeneutics in the Human Sciences

Based on an analysis of double hermeneutics in the human sciences, a distinction between a weak and a strong rhetorical analysis of human-scientific research is introduced, taking account of the self-reflective character of hermeneutic interpretation. The paper argues that there are three hermeneutic topics in the research process for human-scientific experience, which are associated with applying specific rhetorical tools. The three topics are described under the following rubrics: (a) bridging the gap between experience-near and experience-distant concepts; (b) achieving integrity of the cultural objects dispersed in different interpretive strategies; and (c) taking into consideration that an important task of hermeneutic interpretation in human-scientific research is to give an account of the object's immanent narrative coherence. The paper is written in the conviction that a kind of re-methodologization of philosophical hermeneutics which does not rehabilitate epistemological foundationalism can provide a new philosophical identity to the human sciences.     

The Scope and Multidimensionality of the Scientific Realism Debate

At stake in the classical realism-debate is the clash between realist and anti-realist positions. In recent years, the classical form of this debate has undergone a double transformation. On the one hand, the champions of realism began to pay more attention to the interpretative dimensions of scientific research. On the other hand, anti-realists of various sorts realized that the rejection of the hypostatization of a “reality out there” does not imply the denial of working out a philosophically adequate concept of reality. Against the background of this double transformation, new arguments in the realism-debate emerged. The present Introduction is an attempt at systematizing these arguments within the spectrum of doctrines between the poles of scientific realism (exposed and defended by Howard Sankey) and hermeneutic realism (advocated by Dimitri Ginev). The authors try also to demonstrate that after the classical debates the issue of scientism has to be addressed in new ways.     

"Just looking at food makes me gain weight": experimental induction of thought-shape fusion in eating-disordered and non-eating-disordered women

Thought-shape fusion (TSF) is a cognitive distortion that can be induced experimentally and is associated with eating pathology. The current study was conducted in order to elucidate the effects of TSF induction in females with eating disorders (n=35), as well as in restrained eaters (n=38) and unrestrained eaters (n=39). It was hypothesized that TSF induction would result in anxiety, guilt, increased feelings of fatness, perceived weight gain and feelings of moral wrong-doing relative to an anxiety and control induction. It was further hypothesized that restrained eaters and individuals with eating disorders would exhibit a stronger reaction to a TSF induction than would unrestrained eaters. The results indicated that, as predicted, TSF can be induced in individuals both with and without eating disorders, and individuals with eating disorders reported the highest levels of "state" TSF after the induction relative to the non-clinical controls. However, contrary to expectations, restrained eaters reported higher levels of perceived weight gain and moral wrong-doing after the anxiety induction (but not the TSF induction) relative to the control induction. Potential mechanisms for this pattern of results are discussed, and the clinical implications of research on TSF are also considered.     

The smell of cooperativeness: Do human body odours advertise cooperative behaviours?

Several physical features influence the perception of how cooperative a potential partner is. While previous work focused on face and voice, it remains unknown whether body odours influence judgements of cooperativeness and if odour-based judgements are accurate. Here, we first collected axillary odours of cooperative and uncooperative male donors through a public good game and used them as olfactory stimuli in a series of tasks examining whether and how they influence cooperative decision-making in an incentivized economic game and ratings of cooperativeness. Our results show that having access to the donor's body odours provided a strategic advantage to women during economic decisions (but not to men): with age, women were more likely to cooperate with cooperative men and to avoid interacting with uncooperative men. Ratings of cooperativeness were nonetheless unrelated to the donors’ actual cooperativeness. Finally, while men with masculine and intense body odours were judged less cooperative, we found no evidence that donors’ actual cooperativeness was associated with less masculine or less intense body odour. Overall, our findings suggest that, as faces and voices, body odours influence perceived cooperativeness and might be used accurately and in a non-aware manner as olfactory cues of cooperativeness, at least by women.     

A (Post)Foundational Approach to the Philosophy of Science: Part II

Summary  This is a sequel to my paper, “Searching for a (Post)Foundational Approach to Philosophy of Science”, which appeared in an earlier issue of this Journal [Ginev 2001, Journal for General Philosophy of science 32, 27–37]. In the present paper I continue to scrutinize the possibility of a strong hermeneutics of scientific research. My aim is to defend the position of cognitive existentialism that combines the advocacy of science’s cognitive specificity and the rejection of any form of essentialism. A special attention will be paid to the notion of the thematizing project of scientific research.
