Empirical evaluation of a model of global psychophysical judgments: IV. Forms for the weighting function

Understanding the psychological interpretation of numerals is of both practical and theoretical interest. In classical magnitude estimation, respondents match numerals to sensations and in magnitude production they select sensations that stand in a prescribed numerical ratio to a given standard. The present work focusses on evaluating several possible, and related, forms for the function W formulating the distortion of numerals. The main form, of which a power function is a special case, is the Prelec exponential/power representation. Behavioral equivalents to power and to Prelec functions are formulated, tested, and rejected. It is argued that either the mathematical form or the assumption W(1)=1 is wrong. Whereas, the axiomatic literature has focussed exclusively on the former inference, we explore the alternate that W(1)≠1. Behavioral axioms are formulated in each case and experimentally tested. We conclude that most respondents satisfy a general power function and that those who do not, satisfy the general Prelec function.     

On the Persistence of the Genealogical in Contemporary Theology

There is a persistence of genealogical discourse in a certain strand of contemporary theology. Opting for the genealogical shapes the theological task of remembrance and engagement with the historical tradition in important, but also problematic, ways. In this article I discuss how genealogical discourse was appropriated by theology, and then uncover its implicit assumptions and tendencies. Analysing some encounters between theological genealogies and various Hegelian thinkers, I draw a contrast between Nietzschean genealogy and Hegelian ‘phenomenology’. This comparison brings to light some fundamental ways in which the genealogical might distort theological writing and practice.     

Svavarsdóttir’s Burden

It is sometimes observed that the debate between internalists and externalists about moral motivation seems to have reached a deadlock. There are those who do, and those who don??t, recognize the intuitive possibility of amoralists: i.e. people having moral opinions without being motivated to act accordingly. This makes Sigrun Svavarsdóttir??s methodological objection to internalism especially interesting, since it promises to break the deadlock through building a case against internalism (construed as a conceptual thesis), not on such intuitions, but on a methodological principle for empirical investigations. According to the objection, internalists incur the burden of argument, since they have to exclude certain explanations of the (verbal and non-verbal) behavior of apparent amoralists, while externalists don??t. In this paper I argue that the objection fails: the principle for empirical investigations is plausible, but Svavarsdóttir??s application of it to internalism is not. Once we clearly distinguish between the conceptual and the empirical aspects of the internalist and externalist explanations of apparent amoralists, we see that these views incur an equal burden of explanation. I end the paper with a positive suggestion to the effect that there is a third alternative, a view that involves accepting neither internalism nor externalism, which does not incur an explanatory burden of the relevant sort.     

The relationship between physical appearance concerns,disgust, and anti-fat prejudice

This study examined relationships between physical appearance concerns (fear of fat, body image disturbance; BIDQ), disgust, and anti-fat prejudice (dislike, blame), and tested whether disgust mediates relationships between physical appearance concerns and anti-fat prejudice. Participants (N = 1649; age = 28 years) provided demographic data and completed measures of anti-fat prejudice, tendency to feel disgust, and physical appearance concerns. Univariate, multivariate, and mediation analyses were conducted. Univariate and multivariate associations were found between fear of fat, BIDQ, disgust, and anti-fat prejudice for women. For women only, mediation analyses showed that disgust partially mediated relationships between physical appearance concerns and dislike of fat people. For men, univariate and multivariate relationships were found between fear of fat, and dislike and blame of fat people, but disgust was not related to anti-fat prejudice. Newer constructs centering on physical appearance concerns and disgust appear promising candidates for understanding anti-fat prejudice.     

Epistemological notes on recent studies of social perception

Among three possible avenues toward a good society — revolutionary Marxism, liberal‐democratic reform, and radical citizenship education — this paper examines and advocates the third. Societies are held to be ‘good’ so long as the Most Basic Rights are in fact enjoyed by all (i.e. the right (1) to stay alive, (2) to remain unmolested, and (3) to be free to develop one's potentialities). Some key propositions in ‘contract theory’ as represented by such diverse theorists as Socrates, Hobbes, Locke, Rousseau, and Tussman and Meiklejohn are discussed, and an alternative tradition, ‘freedom theory’, is sketched, with contributions from Socrates, Godwin, Thoreau, and Camus. An argument is then developed to the effect that the contract theorists have all contributed to the basis on which the contemporary ‘liberal make‐believe’ rests. This term refers to the myth that our society is democratic, i.e. that working (only) within the system of our constitutional procedures will or can lead toward a just society. Finally, it is argued that the highest priority in citizenship education is to destroy this liberal make‐believe, and that freedom theory provides a better foundation than contract theory in the struggle for human rights, and for mankind's survival.     

Motor inhibition, reflection impulsivity, and trait impulsivity in pathological skin picking

Pathological skin picking (PSP) is often recognized as an impulse control disorder. The current study sought to investigate the relationship between PSP and different forms of impulsivity. University students that met criteria for PSP (n = 55) and university students without history of PSP (n = 55) answered a multidimensional impulsivity questionnaire (the UPPS Impulsive Behavior Scale) and completed 2 neurocognitive tasks that assess impulsivity (the Stop Signal Task and the Information Sampling Task). The PSP group scored significantly higher than the control group on the negative and positive urgency subscales of the UPPS, but the groups did not differ on other subscales or the neurocognitive tasks. Logistic regression demonstrated that the urgency scales added to the prediction of PSP after negative affect and other forms of impulsivity were adjusted for. The results indicate that PSP sufferers are characterized by emotion-based impulsivity and do not appear to be impulsive in other ways.
