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and the sort of ‘primitivism’ that denies that facts of identity and individuality must be analysable has become outdated.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.     

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.     

The role of appraisal in human emotions: a cross-cultural study.

Several theories of emotion propose that emotional responses are largely determined by the way events are appraised. To determine whether the proposed dimensions of appraisal are consistent across cultures, 973 Ss from the United States, Japan, Hong Kong, and the People's Republic of China were asked to describe emotional experiences. Few differences between the 3 cultures were observed on the more primitive dimensions (pleasantness, attentional activity, certainty, coping ability, and goal/need conduciveness) and on 2 of the more cognitively complex dimensions (legitimacy and norm/self compatibility). More substantial differences were observed on 3 other complex dimensions (control, responsibility, and anticipated effort). Considerable pan-cultural consistency was also observed in the dimensions of subjective experience of emotion and in the relations between these dimensions and cognitive appraisals.     

Caricature and face recognition

Although caricatures are often gross distortions of faces, they frequently appear to be super-portraits capable of eliciting recognition better than veridical depictions. This may occur because faces are encoded as distinctive feature deviations from a prototype. The exaggeration of these deviations in a caricature may enhance recognition because it emphasizes the features of the face that are encoded. In two experiments, we tested the superportrait hypothesis and the encoding-by-caricature hypothesis. In the first experiment, caricatures were recognized better than faces, and true caricatures of previously seen faces were recognized better than the faces from which the caricatures had been developed. In the second experiment, faces and their caricatures were tachistoscopically presented in a sequential same/different reaction time task. Subjects were slower to distinguish the stimuli when the face preceded its caricature, indicating that caricatures are more similar to the encoded representation of a face than are stimuli in which the distinctive features are deemphasized.     

Choice in a self-control paradigm: Quantification of experience-based differences

Previous quantitative models of choice in a self-control paradigm (choice between a larger, more-delayed reinforcer and a smaller, less-delayed reinforcer) have not described individual differences. Two experiments are reported that provide additional quantitative data on experience-based differences in choice between reinforcers of varying sizes and delays. In Experiment 1, seven pigeons in a self-control paradigm were exposed to a fading procedure that increased choices of the larger, more-delayed reinforcer through gradually decreasing the delay to the smaller of two equally delayed reinforcers. Three control subjects, exposed to each of the small-reinforcer delays to which the experimental subjects were exposed, but for fewer sessions, demonstrated that lengthy exposure to each of the conditions in the fading procedure may be necessary in order for the increase to occur. In Experiment 2, pigeons with and without fading-procedure exposure chose between reinforcers of varying sizes and delays scheduled according to a concurrent variable-interval variable-interval schedule. In both experiments, pigeons with fading-procedure exposure were more sensitive to variations in reinforcer size than reinforcer delay when compared with pigeons without this exposure. The data were described by the generalized matching law when the relative size of its exponents, representing subjects' relative sensitivity to reinforcer size and delay, were grouped according to subjects' experience.     

Differences in the effect of Pavlovian contingencies upon behavioral momentum using auditory versus visual stimuli.

We examined the role of Pavlovian and operant relations in behavioral momentum by arranging response-contingent alternative reinforcement in one component of a three-component multiple concurrent schedule with rats. This permitted the simultaneous arranging of different response-reinforcer (operant) and stimulus-reinforcer (Pavlovian) contingencies during three baseline conditions. Auditory or visual stimuli were used as discriminative stimuli within the multiple concurrent schedules. Resistance to change of a target response was assessed during a single session of extinction following each baseline condition. The rate of the target response during baseline varied inversely with the rate of response-contingent reinforcement derived from a concurrent source, regardless of whether the discriminative stimuli were auditory or visual. Resistance to change of the target response, however, did depend on the discriminative-stimulus modality. Resistance to change in the presence of visual stimuli was a positive function of the Pavlovian contingencies, whereas resistance to change was unrelated to either the operant or Pavlovian contingencies when the discriminative stimuli were auditory. Stimulus salience may be a factor in determining the differences in resistance to change across sensory modalities.
