Skill theory v2.0: dispositions,emulation, and spatial perception

An attempt is made to defend a general approach to the spatial content of perception, an approach according to which perception is imbued with spatial content in virtue of certain kinds of connections between perceiving organism’s sensory input and its behavioral output. The most important aspect of the defense involves clearly distinguishing two kinds of perceptuo-behavioral skills—the formation of dispositions, and a capacity for emulation. The former, the formation of dispositions, is argued to by the central pivot of spatial content. I provide a neural information processing interpretation of what these dispositions amount to, and describe how dispositions, so understood, are an obvious implementation of Gareth Evans’ proposal on the topic. Furthermore, I describe what sorts of contribution are made by emulation mechanisms, and I also describe exactly how the emulation framework differs from similar but distinct notions with which it is often unhelpfully confused, such as sensorimotor contingencies and forward models.     

Maintaining an open mind to closed individuals: The effect of resource availability and leadership style on the association between openness to experience and organizational commitment

This paper examines whether workplace characteristics, particularly resource availability and transformational leadership, moderate the association between openness to experience and organizational commitment. In Study 1, 205 employees completed a questionnaire that assessed their openness, organizational commitment, and perceived availability of resources at their organization. Openness reduced the extent to which individuals felt obliged to remain loyal to the organization, although this association diminished as resources became more accessible. In Study 2, 312 employees completed a similar questionnaire that also gauged the perceived leadership style of their supervisors. Transformational leadership amplified the positive relationship between openness and organizational commitment. These findings align with the proposition that individuals are more committed in work environments that facilitate the expression of their traits.     

Ontogeny of sex differences in defensive burying behavior in rats: effect of social isolation

The aim of the present experiments was to clarify sex differences in socio-developmental factors that affected defense behavior in rats. Sex differences in the defensive burying behavior of rats, and related social factors, were explored in three developmental stages: juvenile, puberty, and adult; 30, 50, and 80 days of age, respectively. The duration of burying, digging into bedding material, stretch-attend postures, and crouch/freezing were measured in a shock-prod test. For males, the duration of burying was longer in the juvenile and pubertal stages than in adulthood. For females, no age differences in the duration of burying were found. Males showed longer burying durations than females in both the juvenile and pubertal stages. For both sexes, the highest duration of digging was found in the juvenile stage, and females showed longer durations of digging than males. Both male and female rats isolated during the juvenile stage, from 26 to 40 days of age, showed smaller durations of burying behavior compared to pair-reared rats. This effect of juvenile isolation was maintained among both adult males and females even when they were returned to pair rearing after isolation. Isolation during adulthood, from 66 to 80 days of age, increased burying behavior in males, but decreased it in females. The durations of digging, stretch-attend postures, and crouch/freezing were not affected by isolation. The decrease in defensive burying and its increase resulting from isolation in adult male rats, suggest that the emergence of adult-like social relationships in males suppressed the duration of burying. Male and female rats isolated during the juvenile stage maintained lower levels of burying, suggesting that social experience as juveniles is important for the emergence of defensive burying behavior.     

A unity of the self or a multiplicity of locations? How the graphesthesia task sheds light on the role of spatial perspectives in bodily self-consciousness

Integrating multisensory stimuli from a self-centred perspective is crucial for the unity of the self. On the other hand, understanding external space and communicating spatial knowledge with others necessitate the adoption of decentred perspectives. How do we juggle these two requirements? In this article, we review those studies that have used the graphesthesia task in order to investigate the perspectives that people adopt when interpreting ambiguous tactile symbols (e.g., b, d, p, and q). With such ambiguous symbols, self-centred and decentred perspectives conflict with one another. The results reviewed here reveal that the perspectives adopted vary significantly with spatial, personal, and interpersonal factors. Such findings suggest that the self can adopt a multiplicity of spatial locations. However, the unity of the self can partly be explained by the predominance of a head-centred perspective. On the other hand, perspective-taking abilities contribute to the distinction between self and others, reinforcing self-consciousness.     

Interviewing asylum seekers: A vignette study on the questions asked to assess credibility of claims about origin and persecution

The aim of the current vignette study is to map the style, type, and themes of questions that are asked when assessing the credibility of asylum seekers' claims. Sixty‐five officials from the Swedish Migration Agency (Migrationsverket ), were asked to respond to one out of four different vignettes that contained fictitious asylum narratives. Each vignette presented the types of problems often encountered by officials at the migration board. Two of the vignettes contained no evidence of the origin of the asylum seeker. The other two contained no evidence for the claim of persecution. The asylum officials were asked to formulate five questions that would help them to assess the veracity of the applicant's claim. Our analyses showed that they mainly formulated open questions in an information gathering style. A thematic analysis of the questions revealed that when a claim about origin was assessed, asylum officials mostly asked questions about life in the country of origin, identity documents, and the flight to Europe. When the claim about persecution was assessed, in contrast, asylum officials mostly formulated case‐specific questions (e.g., how the applicant was arrested). Hence, when the credibility of claims about origin is assessed, there seems to be a typical set of questions that asylum officials use. The asylum officials seem to assume that if the applicant is truly originating from a specific country or area, he or she should have ample knowledge about that area, its customs, and frequently encountered objects.     

From body shadows to bodily attention: Automatic orienting of tactile attention driven by cast shadows

Body shadows orient attention to the body-part casting the shadow. We have investigated the automaticity of this phenomenon, by addressing its time-course and its resistance to contextual manipulations. When targets were tactile stimuli at the hands (Exp.1) or visual stimuli near the body-shadow (Exp.2), cueing effects emerged regardless of the delay between shadow and target onset (100, 600, 1200, 2400 ms). This suggests a fast and sustained attention orienting to body-shadows, that involves both the space occupied by shadows (extra-personal space) and the space the shadow refers to (own body). When target type became unpredictable (tactile or visual), shadow-cueing effects remained robust only for tactile targets, as visual stimuli showed no overall reliable effects, regardless of whether they occurred near the shadow (Exp.3) or near the body (Exp.4). We conclude that mandatory attention shifts triggered by body-shadows are limited to tactile targets and, instead, are less automatic for visual stimuli.     

Pour une poétique des jeux de langage

Malgré le refus que Wittgenstein semble avoir toujours opposé à l'idée d'une esthétique philosophique, son oeuvre et les nombreuses suggestions que contiennent ses divers propos se révélent riches d'enseignements, en particulier pour ce qui concerne les voies dans lesquelles certaines formes de discours sur l'art se sot engagées. La notion wittgensteinienne dejeu de langage est, sous ce rapport, éclairante. Elle permet de mettre au jour, ou du moins d'entrevoir, deux catégories de faits. Tout d'abord, elle offre une perspective critique intéressante sur le programme de ce que l'on s'est plu à nommer une poétique, dans le prolongement d'Aristote, de Jakobson et de Valéry. La poétique structuraliste, en particulier, se révéle solidaire d'une philosophie que ses ambitions théoriques ne suffisent pas à occulter. En second lieu, la notion de jeu de langage, chez Wittgenstein lui-même, est associée à une pratique d'écriture originale qui obscurcit les frontiéres que la philosophie, depuis Platon, s'est toujours souciée de tracer. Pour une poétique des jeux de langage, il existe, entre la poétique et la philosophie une double symétrie. La premiére — celle des structuralistes ou des néo-structuralistes —obéit à un programme plus philosophique qu'on ne croit; la second, en revanche, comme on le voit avec Wittgenstein, intégr une démarche poétique qui nous invite à penser à nouveaux frais ce que nous faisons.     

Supervisory styles index: Examining supervisees' perceptions of Supervisory Style

The goal of this research was to develop an instrument, the Supervisory Styles Index (SSI), that would examine supervisory style. Style has been described as the way in which the personality and convictions of the supervisor are demonstrated in the supervisory relationship (Leighton, 1991). This study focuses on the interplay between supervisory style and the influence of sex and gender. The findings of this study reveal that female supervisees discern their supervisors to be more self-disclosing than do male supervisees. Implications of the findings and utilization of the index are discussed.Portions of this paper were presented at the 52nd annual conference of the American Association for Marriage and Family Therapy, Chicago, Illinois, November, 1994.     

Event-specific attributions and daily life events as predictors of depression symptom change

A prospective study was conducted to investigate whether event-specific attributions, either alone or in interaction with daily life events predict depression symptom change, and whether this is affected by systematic variation in intertest intervals. Baseline measures of attributional style, event-specific attributions, life events, and depression were administered to 96 adults enrolled in a cigarette-smoking cessation program who were readministered the event-specific attributions, life events, and depression measures 2, 4, 6, and 8 weeks later. Results indicated that (a) the interaction between event-specific attributions and life events was a better predictor of depression symptom change than were event-specific attributions alone; (b) event-specific attributions and life events demonstrated a tendency to predict depression symptom change over 2 and 4 weeks but not over 6 and 8 weeks; (c) the stability and globality of event-specific attributions was associated with the number of reported life events; and (d) baseline attributional style predicted event-specific attributions 2, 4, 6, and 8 weeks later.
