HOW TO TALK TO YOURSELF OR KRIPKE's WITTGENSTEIN's SOLITARY LANGUAGE ARGUMENT AND WHY IT FAILS

Abstract: In Wittgenstein on Rules and Private Language, Kripke's Wittgenstein argues that it is possible for individuals in communities to speak a language and otherwise follow rules, but impossible for a single, conceptually isolated individual to do so. I show that the roots of the argument lie in his general account of the legitimacy of practices, and that he actually argues for two distinct conclusions: (a) solitary individuals cannot have useful practices of rule‐following and (b) solitary individuals cannot place substantive restrictions on their own behavior. I show that if it is, in fact, possible for individuals in communities to use language and follow rules, then both of Kripke's Wittgenstein's anti‐solitary language arguments fails; and, furthermore, that his general account not only fails to exclude the possibility of solitary language‐use and rule‐following, it actually guarantees their possibility.     

MMPI profiles of adolescents charged with homicide

Study of adolescent violence has been impeded by failure to distinguish among the circumstances in which youth engage in violent behavior. The present study investigated MMPI profiles of 36 adolescent murderers and a control group of 18 adolescents charged with larceny. Homicide cases were subgrouped into those who committed homicide secondary to another crime (e.g., robbery or rape) and those who acted in the context of interpersonal conflict with the victim. While there were no significant differences between homicide and larceny groups, crime and conflict subgroups were significantly different on scales F, Hs, Hy, and Sc.     

Rorschach object relations of adolescents who committed homicide.

We investigated the object relations of adolescents who committed homicide. A clinical sample of 55 adolescents who committed homicide did not differ from a comparison group of nonviolent delinquents on Rorschach measures of object differentiation, mutuality of autonomy, and aggressive content. However, the subgroup of adolescents who committed homicides in the context of another crime (e.g., robbery or burglary) did manifest significantly lower object relations (poorer object differentiation and more victim responses) than the subgroup of adolescents whose homicides were committed in the context of an interpersonal conflict or dispute with the victim. These findings support the need for differentiated classification of violent individuals as urged by Megargee (1970) over 20 years ago.     

The effects of area and perimeter on detection rates

The detection of luminance increments in a homogeneously lighted field was studied as a function of the area and perimeter of the luminance increment. Sixteen targets representing all possible combinations of four values of area and four values of perimeter were foveally presented. Exposure durations were short (25 to 40 msec). Results of both an analysis of variance and linear discriminant analysis indicated that detection probability increases as area increases, but neither variations in perimeter nor perimeter-area combinations produced effects that were significant oyer the experiment as a whole. The linear discriminant analysis revealed individual differences in the effects of perimeter and area on detection probability. Results were contradictory to Kristofferson’s (1957) “element contribution theory” and gave only slight support to Hecht’s (Lamar, Hecht, Shlaer, & Hendley, 1947) “border-quantum theory.”

Discursive logic towards a logic of rational discourse

Both logic and philosophy of science investigate formal aspects of scientific discourse, i.e. properties of (non-monotonic) consequence operations for discursive logic. In the present paper we handle two of them: paraconsistency and enthymematycity.Supported by grants from the Alexander von Humboldt-Stiftung, form the Fulbright-Foundation and from the Center for Philosophy of Science at the University of Pittsburgh.Presented byJan Zygmunt     

On the Relation between Representational and Processing Models of Asyntactic Comprehension

Most accounts of asyntactic comprehension fall along a spectrum from pure representational accounts to pure processing accounts. The double dependency hypothesis of Mauner, Fromkin, and Cornell (1993) is an example of the former, while the SYNCHRON model of Haarman and Kolk (1991; see also Kolk, this volume) is an example of the latter. This paper attempts to demonstrate some of the ways that these two approaches interact. We introduce GENCHRON, a computer model based on Haarman and Kolk′s SYNCHRON. GENCHRON is a parser subject to the kinds of processing deficits examined in Haarman and Kolk (1991). We present a simple grammar which leads GENCHRON to produce the kinds of semantic representations which Mauner, Fromkin, and Cornell (1993) propose for asyntactic comprehenders.
