Referenzsemantik in der Partnermodellierung

How can we explain that an assertion on something perceived can be understood in the same manner by somebody who cannot perceive that scene? This problem bases the interest in computational linguistics in how listener modeling could possibly be harmonized with reference semantics. Mental images substituting real perception appear as a way out. The architecture of the listener model has to be adapted to the creation and use of such pictorial data structures. Furthermore, the relation between the latter and a verbal (i. e., propositional) representation must be understood. The resulting architecture of a listener model with reference semantics can be employed to solve communicational problems from three general classes in a better way, as is demonstrated by an example implementation.     

Deterrence, Opportunity, and Choice

Traditional studies of deterrence have focused on punishment with less regard for the rewards of both crime and noncrime. Influenced by work in economics and behavioral psychology, more recent studies have departed from tradition by incorporating rewards for crime. To this extent, they should be regarded as advances over the more traditional approaches. Notwithstanding these advances, variations in both the probability and magnitude of reward for noncrime have not been systematically included in these more recent theories of choice. In an attempt to determine whether opportunities for noncrime are either central or trivial to the criminal decision-making process, the present study fitted two alternative models to experimental data involving risk-taking: (a) the economic utility model employed by Piliavin, Gartner, Thornton, and Matsueda (1986) in their study of criminal choice; and (b) the satisfaction balance model developed by Gray and Tallman (1984). Results showed that while both models explained significant amounts of variation in the dependent variable, the Gray-Tallman model provided a substantially better fit of the data. Despite limitations inherent in experimental studies as, for example, limitations surrounding the issue of external validity, the findings strongly suggest that opportunities for noncrime are as important as rewards and costs for crime in the process by which criminal decisions are made.     

The Heritability of Characteristics Associated with Dispositional Empathy

ABSTRACT This investigation used data from Loehlin and Nichols's (1976) study of over 800 sets of twins to examine evidence for the heritability of three facets of empathy: empathic concern, personal distress, and perspective taking. Expert judges first identified sets of adjectives, included within Loehlin and Nichols's original data, which reflected each empathy construct; these items were then validated in an independent sample. Comparisons of the responses given to these items by identical and fraternal twins in the Loehlin and Nichols investigation revealed evidence of significant heritability for characteristics associated with the two affective facets of empathy—empathic concern and personal distress—but not for the nonaffective construct of perspective taking. This pattern is consistent with the view that temperamental emotionality may underlie the heritability of affective empathy.     

Attachement,solitude et détresse psychologique chez des jeunes adultes

La présente étude vise à examiner la nature des liens entre les styles d'attachement (sécurisant, anxieux/ambivalent et évitant), la solitude et la détresse psychologique (dépression, anxiété, agressivité et problèmes cognitifs) chez des jeunes adultes. L'échantillon se compose de 407 étudiants de niveau collégial dont l'âge moyen se situe à 18 ans. Les sujets doivent répondre à deux questionnaires d'évaluation du style d'attachement, à l'échelle de solitude UCLA, ainsi qu'à l'index de symptômes psychiatriques. Les résultats laissent voir que les individus ayant un style d'attachement sécurisant rapportent moins de symptômes de dépression et de sentiments de solitude que les sujets des styles anxieux/ambivalent et évitant. De même, ils vivent moins d'anxiété, d'agressivité et de problèmes cognitifs que les individus du style anxieux/ambivalent. Par ailleurs, les individus du style d'attachement anxieux/ambivalent sont plus déprimés, anxieux et agressifs que les individus du style évitant. Par contre, aucune différence significative ne ressort entre les sujets des styles d'attachement anxieux/ambivalent et évitant sur le plan des problèmes cognitifs et de la solitude. Des analyses de régression multiple montrent que l'attachement anxieux/ambivalent et la solitude expliquent un pourcentage significatif de la variance associée à la détresse psychologique. Enfin, il ressort que la solitude joue un rôle modérateur dans la relation unissant l'attachement non sécurisant et les problèmes de nature cognitive, alors qu'elle joue un rôle médiateur dans la relation entre l'attachement sécurisant, la dépression et l'anxiété.     

A platonist epistemology

A response is given here to Benacerraf's 1973 argument that mathematical platonism is incompatible with a naturalistic epistemology. Unlike almost all previous platonist responses to Benacerraf, the response given here is positive rather than negative; that is, rather than trying to find a problem with Benacerraf's argument, I accept his challenge and meet it head on by constructing an epistemology of abstract (i.e., aspatial and atemporal) mathematical objects. Thus, I show that spatio-temporal creatures like ourselves can attain knowledge about mathematical objects by simply explaininghow they can do this. My argument is based upon the adoption of a particular version of platonism — full-blooded platonism — which asserts that any mathematical object which possiblycould exist actuallydoes exist.I would like to thank the following people for their helpful comments on earlier versions of this paper: Arnold Koslow, Hartry Field, Jerrold Katz, Michael Resnik, Elliott Mendelson, Charles Landesman, Stephen Schiffer, Adam Vinueza, David Pitt, Jody Azzouni, David MacCallum, Colin McLarty, Tom Slaughter, Henry Mendell, Penelope Maddy, Michael Liston, Ricardo Gomez, Seth Crook, Stuart Cornwell, and various people at the University of Colorado, Boulder, where I read this paper in February, 1994.

College Counseling: Union and Intersection

College counseling can best be understood as the intersection of a professional activity and an environment. The specialty has developed from the merging of several movements: vocational guidance, mental health, and student personnel work. These elements are reflected in the diversity of backgrounds and perspectives represented by college counselors and in differing models of counseling services. College counseling will be affected by trends including health care reform, scarcity of resources in higher education, changing student demographics, and complex societal issues.
