Revisiting the learning-without-awareness question in human pavlovian autonomic conditioning: Focus on extinction in a dichotic listening paradigm

Numerous studies have indicated that, consistent with current “cognitive” accounts of information processing, human Pavlovian autonomic discrimination acquisition cannot occur without awareness of the CS-US relationship. However, extinction studies have suggested that awareness is not necessary, findings that, in information-processing terms, have been explained by assuming that the processing by the extinction stage is parallel (automatic) rather than serial (controlled). This explanation was tested in an 80-subject study. The first, acquisition phase was a standard semantic differential conditioning arrangement with a 96-db white noise as US, and a “long” CS-US interval of 8 s, with ten trials each of CS+ (paired with US) and CS− (unpaired) trials. In extinction (USs omitted), in order to obtain non-autonomic indices of processing and thereby test the information-processing account of “unaware” autonomic conditioning during extinction, a dichotic listening task was implemented, with the CSs presented in the unattended channel (ear), while the subject had to perform a semantic differential reaction task in an attended-to channel (other ear). In early extinction, the electrodermal response occurring at an interval of 9–15 s after CS onset (i.e., following placement of the US during acquisition) and the finger-pulse-volume response occurring at an interval of 4–11 s after CS onset both showed reliable conditioning, but reaction-time and subjective-report data for the recognized critical words indicated serial rather than parallel processing of the CSs during extinction.     

A Neo-Kantian foundation of Corporate Social Responsibility

‘Corporate Social Responsibility (CSR) is conceptualized in many ways. We argue that one cannot be indifferent about the issue of its conceptualization. In terms of methodology, our position is that any conceptual discussion must embed CSR in political theory. With regard to substance, we link up with the discussion on whether CSR must be defined on the basis of a tripartite or a quadripartite division of business responsibilities. We share A.B. Carroll’s intuition that a quadripartite division is called for as a basis to define CSR. However, defending the quadripartite division of business responsibilities requires that the distinctions between economic, legal, ethical and discretionary business responsibilities be made intelligible. Carroll’s account is defective in this respect. We argue that contemporary Neo-Kantian political ethics is able to make sense of these distinctions, because of its specific interpretation of liberalism. Interestingly, from a conventional liberal perspective this interpretation of liberalism is atypical, as it extends public morality beyond the domain of the law.

The philosophical legacy of Meehl (1978): confirmation theory, theory quality, and scientific epistemology

The reach and impact of Paul Meehl’s work is extraordinary. Focusing on his “Theoretical Risks and Tabular Asterisks”, I trace three consequences of his findings. The first is the influence of his work on confirmation theory in the philosophy of science, in which he provided a more sophisticated alternative to Popperianism, despite some affinities with it. The second is a clear focus on the evaluation of theory quality as an explanation for the success of hard vs. soft theories. The third is a very deep critique of the practices of contemporary epistemology; his research recommends the replacement of demonstrably unreliable, subjective judgments about justification and knowledge with simple predictive models that outperform human experts. This is an impressive array of intellectual contributions to psychology and philosophy. As influential as his work was, it is just now beginning to receive attention commensurate with its merits.     

Sin and bioethics.

The essay starts out with defining the biblical concept of sin in the Old and the New Testaments. The literal knowledge of divine truth is distinguished from its truthful and spiritual interpretation. A further distinction should be made between the Creator of life (God) and the medium or "intermediary creator" (man) of life. I argue for the "single wholeness" of the human race and for the unity of human responsibility in bioethics. In delineating the teaching of the Church on abortion and family planning, I show that the healing of all human diseases, from traditional interventions to genetic ones, is a Christian duty and is in accordance with Christ's mission on earth as long as one has not been directly or indirectly involved in "reproducing" or "designing" one's descendants or destroying or damaging human life even at its very beginnings.     

The importance of the individual in the ‘causal’ relationship between attractiveness and self-esteem

This paper argues that many psychological explanations underlying health and social behaviour stress the importance of the relationship between attractiveness and self-esteem. The nature of this relationship is not well understood, yet can have important implications for the individual in areas of medical intervention which involve treatment on aesthetic grounds. A survey of psychosocial factors among 1018 children aged 11-12 years is reported. The study examined the association between perception of physical attractiveness and self-esteem in order to clarify the relationship between self-esteem and self versus others' perception of attractiveness. Self-ratings of attractiveness were linked to judges' ratings to determine whether subjects underrated, over-rated, or accurately perceived their own physical attractiveness. The results showed that although ratings of general facial attractiveness by others were associated with self-perceived attractiveness, in the specific area of dental health, attractiveness (as judged by others) was not. There were no significant relationships between ratings of attractiveness by others and self-esteem. Self-perception of attractiveness, however, was significantly associated with self-esteem. Further analyses showed that children who under-rated their own facial attractiveness had a lower mean score for self-esteem than over-raters or accurate perceivers (who did not differ significantly). In contrast, under-raters of dental attractiveness had a lower mean score for self-esteem than over-raters, but did not differ significantly from accurate perceivers. Over-raters of dental attractiveness had a higher mean score for self-esteem than accurate perceivers. These finding suggest that if an over-rater were to receive treatment on aesthetic grounds it is unlikely, given that they have high self-esteem already, that such intervention will have a profound psychological impact. These data indicate the importance of determining the way in which individuals evaluate their appearance compared to others, and may help to clarify previously equivocal findings concerning the relationship between self-esteem and attractiveness.
