Continuous Grey Scales Versus Sharp Contrasts: Styles of Representation in Italian Clinical Cytogenetics Laboratories

In some circumstances, scientists of the same discipline visualize and view differently the same scientific object. The question of representational difference, which has usually been connected to scientific revolutions or controversies, is framed here using the concept of “style,” addressing the plurality of scientific traditions within a well-established scientific field. Using ethnomethodology we will examine the divergences of representational practices that, beyond the apparent consensus of a scientific community, are present throughout the procedure of chromosomes preparation. The ethnographic data was gathered through participant observation and in-depth interviews in several Italian clinical cytogenetic laboratories. The concept of style emerges through the examination of the two alternate, and sometimes conflicting, ways of configuring the complex texture of practice, instrumental mediation, epistemic virtues, and expertise involved in scientific representation of chromosomes. Resonating with the recent debate on objectivity, it tries to articulate the concept of “epistemic virtue” outside an internalised scientific self through an aesthetic, analytical, instrumental, and ontological preferences in the current manners to produce and see the same research object.     

Grades of individuality. A pluralistic view of identity in quantum mechanics and in the sciences

This paper offers a critical assessment of the current state of the debate about the identity and individuality of material objects. Its main aim, in particular, is to show that, in a sense to be carefully specified, the opposition between the Leibnizian ‘reductionist’ tradition, based on discernibility, and the sort of ‘primitivism’ that denies that facts of identity and individuality must be analysable has become outdated. In particular, it is argued that—contrary to a widespread consensus—‘naturalised’ metaphysics supports both the acceptability of non-qualitatively grounded (both ‘contextual’ and intrinsic) identity and a pluralistic approach to individuality and individuation. A case study is offered that focuses on non-relativistic quantum mechanics, in the context of which primitivism about identity and individuality, rather than being regarded as unscientific, is on the contrary suggested to be preferable to the complicated forms of reductionism that have recently been proposed. More generally, by assuming a plausible form of anti-reductionism about scientific theories and domains, it is claimed that science can be regarded as compatible with, or even as suggesting, the existence of a series of equally plausible grades of individuality. The kind of individuality that prevails in a certain context and at a given level can be ascertained only on the basis of the specific scientific theory at hand.     

How to Make Decisions in An Uncertain World: Heuristics,Biases, and Risk Perception

From the seventies onward a large quantity of theoretical and empirical studies have investigated the heuristic principles and cognitive strategies that individuals use to deal with risky and uncertain situations. This research has shown how the explicative and predictive shortcomings of normative risk analysis depend in many respects on undervaluing the continuous interaction between the individual and the environment. There are factors that, day by day, represent significant obstacles to decision making.     

Processing emotional category congruency between emotional facial expressions and emotional words

Facial expressions are critical for effective social communication, and as such may be processed by the visual system even when it might be advantageous to ignore them. Previous research has shown that categorising emotional words was impaired when faces of a conflicting valence were simultaneously presented. In the present study, we examined whether emotional word categorisation would also be impaired when faces of the same (negative) valence but different emotional category (either angry, sad or fearful) were simultaneously presented. Behavioural results provided evidence for involuntary processing of basic emotional facial expression category, with slower word categorisation when the face and word categories were incongruent (e.g., angry word and sad face) than congruent (e.g., angry word and angry face). Event-related potentials (ERPs) time-locked to the presentation of the word–face pairs also revealed that emotional category congruency effects were evident from approximately 170 ms after stimulus onset.     

Gastroesophageal reflux disease: attachment style and parental bonding

The attachment styles and parental bonding of 72 patients (M age= 45.3 yr., SD=13.5) suffering from Gastroesophageal Reflux Disease were compared with those of 105 healthy subjects (M age =44.9 yr., SD = 5.8). A clinical interview and two questionnaires, the Attachment Style Questionnaire and the Parental Bonding Instrument, showed that the scores on the ASQ Confidence subscale were significantly lower in the clinical group. Similar results were obtained for the Discomfort with Closeness subscale in the subsample with Pure Gastroesophageal Reflux Disease. The results indicate Insecure Attachment in the clinical sample. The results obtained from the Parental Bonding Instrument indicate that scores on the Protection Mother scale were significantly higher in the clinical subjects, suggesting a Low Care-High Protection combination (Affectiveless Control), at least for patients with pure Gastroesophageal Reflux Disease. These characteristics can be considered important factors in the tendency to somatization. The symptoms may have a paradoxically normalising function while the patient shows an emotional detachment towards intimate relationships. The illness appears to act as a bond through which the relationship with the caregivers is maintained.     

Attachment representations in adults with congenital blindness: association with maternal interactive behaviors during childhood

This study explores how maternal interactive behaviors experienced during the childhood of adults with congenital blindness are associated with their subsequent development and personality. Many researchers have found a high frequency of maternal directiveness and overprotection in sighted mother-congenitally blind child relationships. One open question is whether these behaviors may have negative effects on congenitally blind children's subsequent development, or whether they may have a functionally adaptive-strategic role. The purpose of this study was to discriminate between the two hypotheses. This objective was pursued by adopting the theory of attachment and administering the Adult Attachment Interview to 15 participants with congenital blindness. Results suggested that directive and overprotective maternal behaviors are experienced by the persons with congenital blindness as encouraging and functional as long as they are accompanied by an affective, loving, and supportive attitude. Results did not support the hypothesis that directive and overprotective maternal interactive behaviors have a necessarily negative effect on the development of persons with congenital blindness.     

Adaptation of the MSCI for the measurement of cohesion in Spanish young soccer players

This work describes the Spanish adaptation and studies the psychometric properties of Yukelson, Weinberg, and Jackson's Multidimensional Sport Cohesion Instrument (MSCI) with a sample of 173 soccer players. The Spanish version is composed of 22 items grouped in four factors: quality of teamwork (performance aspects), attraction to the group, valued roles and quality of teamwork (interpersonal relationships), that accounted for 53.30% of the total variance. Reliability coefficients (Cronbach's Alphas) for the factors ranged from .84 (factor 1) to .56 (factor 4). Suggestions are made for future research on the validity of the scale, mainly in terms of convergence with other multidimensional measures of sport cohesion.     

Visual experience is not necessary for efficient survey spatial cognition: evidence from blindness

This study investigated whether the lack of visual experience affects the ability to create spatial inferential representations of the survey type. We compared the performance of persons with congenital blindness and that of blindfolded sighted persons on four survey representation-based tasks (Experiment 1). Results showed that persons with blindness performed better than blindfolded sighted controls. We repeated the same tests introducing a third group of persons with late blindness (Experiment 2). This last group performed better than blindfolded sighted participants, whereas differences between participants with late and congenital blindness were nonsignificant. The present findings are compatible with results of other studies, which found that when visual perception is lacking, skill in gathering environmental spatial information provided by nonvisual modalities may contribute to a proper spatial encoding. It is concluded that, although it cannot be asserted that total lack of visual experience incurs no cost, our findings are further evidence that visual experience is not a necessary condition for the development of spatial inferential complex representations.
