Calibration of sensory and cognitive judgments: A single model for both

In a recent issue of this journal, Winman and Juslin (34 , 135–148, 1993) present a model of the calibration of subjective probability judgments for sensory discrimination tasks. They claim that the model predicts a pervasive underconfidence bias observed in such tasks, and present evidence from a training experiment that they interpret as supporting the notion that different models are needed to describe judgment of confidence in sensory and in cognitive tasks. The model is actually part of the more comprehensive decision variable partition model of subjective probability calibration that was originally proposed in Ferrell and McGoey (Organizational Behavior and Human Performance, 26 , 32–53, 1980). The characteristics of the model are described and it is demonstrated that the model does not predict underconfidence, that it is fully compatible with the overconfidence frequently found in calibration studies with cognitive tasks, and that it well represents experimental results from such studies. It is concluded that only a single model is needed for both types of task.     

Mood and realism of confidence judgements of one''s own answers to general knowledge questions

This study examines the effect of a depressed mood on the realism of subjects' confidence judgements of the correctness of answers to general knowledge questions. Research conducted on how mood influences cognitive processes gives reason to expect that a depressed mood might increase the realism of individuals' confidence ratings. Sixty subjects were divided into three conditions, two of which were given mood induction, one condition into an elated-happy mood and one condition into a depressed-sad mood. As evidenced by subjects' responses to mood scales only the depressed condition was affected by the mood induction. All subjects answered 93 general knowledge questions and rated their confidence in the correctness of the answer given. Subjects were instructed to think aloud when answering the last 31 questions. The conditions did not differ with respect to the proportion of questions answered correctly, mean level of confidence, nor with respect to three measures of the realism in subjects' confidence ratings (calibration, over/underconfidence and resolution). The results were the same when questions answered with and without think aloud instructions were analysed separately.     

Value and Obligation Once More

In Understanding Moral Obligation (2012), Robert Stern sets out to provide a fresh interpretation of the role of autonomy in Kant's moral philosophy and attempts to rectify J. B. Schneewind's standard account in The Invention of Autonomy (1998). While Stern agrees that Kant's resort to autonomy is at the basis of a constructivist account of moral obligation, he claims that autonomy plays no role in Kant's theory of value, such that, in this respect, Kant remains a realist. Accordingly, Stern characterizes Kant's moral philosophy as a “hybrid” view because he sees it as involving a compromise between realism with regard to value and constructivism with regard to obligation. Stern's interpretation relies on a sharp distinction between value and obligation. The purpose of the present article is to question Stern's reliance on that rigid distinction, which involves intermixing theoretical and practical reason and assumes a distorted view of human agency.     

Forms of Quantum Nonseparability and Related Philosophical Consequences

Standard quantum mechanics unquestionably violates the separability principle that classical physics (be it point-like analytic, statistical, or field-theoretic) accustomed us to consider as valid. In this paper, quantum nonseparability is viewed as a consequence of the Hilbert-space quantum mechanical formalism, avoiding thus any direct recourse to the ramifications of Kochen-Specker’s argument or Bell’s inequality. Depending on the mode of assignment of states to physical systems – unit state vectors versus non-idempotent density operators – we distinguish between strong/relational and weak/deconstructional forms of quantum nonseparability. The origin of the latter is traced down and discussed at length, whereas its relation to the all important concept of potentiality in forming a coherent picture of the puzzling entangled interconnections among spatially separated systems is also considered. Finally, certain philosophical consequences of quantum non-separability concerning the nature of quantum objects, the question of realism in quantum mechanics, and possible limitations in revealing the actual character of physical reality in its entirety are explored.     

Age constraints on first versus second language acquisition: evidence for linguistic plasticity and epigenesis

Does age constrain the outcome of all language acquisition equally regardless of whether the language is a first or second one? To test this hypothesis, the English grammatical abilities of deaf and hearing adults who either did or did not have linguistic experience (spoken or signed) during early childhood were investigated with two tasks, timed grammatical judgement and untimed sentence to picture matching. Findings showed that adults who acquired a language in early life performed at near-native levels on a second language regardless of whether they were hearing or deaf or whether the early language was spoken or signed. By contrast, deaf adults who experienced little or no accessible language in early life performed poorly. These results indicate that the onset of language acquisition in early human development dramatically alters the capacity to learn language throughout life, independent of the sensory-motor form of the early experience.     

The Logic of Instance Ontology

An ontology's theory of ontic predication has implications for the concomitant predicate logic. Remarkable in its analytic power for both ontology and logic is the here developed Particularized Predicate Logic (PPL), the logic inherent in the realist version of the doctrine of unit or individuated predicates. PPL, as axiomatized and proven consistent below, is a three-sorted impredicative intensional logic with identity, having variables ranging over individuals x, intensions R, and instances of intensions Ri. The power of PPL is illustrated by its clarification of the self-referential nature of impredicative definitions and its distinguishing between legitimate and illegitimate forms. With a well-motivated refinement on the axiom of comprehension, PPL is, in effect, a higher-order logic without a forced stratification of predicates into types or the use of other ad hoc restrictions. The Russell–Priest characterization of the classic self-referential paradoxes is used to show how PPL diagnosis and solves these antimonies. A direct application of PPL is made to Grelling's Paradox. Also shown is how PPL can distinguish between identity and indiscernibility.     

The Image of God of Neurotheology: Reflections of Culturally Based Religious Commitments or Evolutionarily Based Neuroscientific Theories?

In Augustinian fashion, James B. Ashbrook and Carol Rausch Albright develop a neurotheology that finds evolutionarily based correlations between the functions of the human mind-brain and the roles God plays in human life. I argue that their assumptions of anthropomorphism , that the human mind-brain must conceptualize its environment in human terms, and realism , that anthropomorphism is correct, are evolutionarily unlikely. I conclude that the image of God ( imago dei ) the authors find reflected in the human mind-brain appears to derive from their Christian religious commitments rather than from evolutionary theory.     

A Liberation Psychology Approach to Acculturative Integration of Migrant Populations

This paper describes an acculturative integration approach that stresses the contribution of liberation psychology. Immigrant integration is a challenge for receiving countries in the Western world due to the frequent asymmetrical and oppressive conditions suffered by newcomers in their new settlements. The cross-cultural perspective connects integration with psychological acculturation, emphasizing harmony between acquisitions of the new culture while maintaining cultural heritage, and creating opportunities for intergroup relationships. In turn, liberation psychology permits an understanding of the acculturative transition as an empowerment and self-construction process by which immigrants acquire a new vision of the world and of themselves, transforming both structural conditions and themselves. From this perspective we conceptualize acculturative integration as the process by which newcomers become an accepted part of the new society through a reflexive and evaluative process, changing their social references and position, rebuilding their social and personal resources, and achieving a new agency in coherence with their new challenges and goals. In this process, they acquire critical thinking about unequal conditions, gain capacities to respond to the inequalities, and take effective actions to confront them. We illustrate this process using the narratives of nine Moroccan women who are living in asymmetrical and oppressive local contexts in Andalusia, the southern-most region of Spain.
