The composite measure of the defense mechanism inventory

A reanalysis of previously published data suggests that the Defense Mechanism Inventory can be utilized to yield a composite measure of reaction to frustration by contrasting linearly the defenses of Turning-against-object and Projection against those of Principalization and Reversal-of-affect. Factor-analytic and correlational data support the exclusion of Turning-against-self from the composite measure. Studies of content validity are presented for the combination of the four defenses into one dimension. Patterns of interitem reliability are charted for the five defenses and the composite measure for both men and women. Internal consistency data are also presented for the standard scoring as well as for a modified method to explore the feasibility of simplifying and shortening the test-taking procedure.     

Locale,Street, Square—a Naive Theory of the City

The paper outline three basic categories of urban phenomenology based upon the simple notion of a trajectory thorough a network of streets. This formal notion gives rise to three different phases of such a trajectory—where the movement stops, when it proceeds unproblematically, and when several possibilities for choosing the further trajectory present themselves; thus, the locale, the street, and the square, as indicated in the title. Based on the Peircean notions of First-, Second-, and Thirdness, the paper makes a first investigation as to which aspects of urban experience are connected to these three categories.     

Conceptual combination with prototype concepts

This paper deals with how people combine simple, prototype concepts into complex ones; e.g., how people combine the prototypes for brown and apple so they can determine the typicality of objects in the conjunction brown apple. We first consider a proposal from fuzzy-set theory (Zadeh, 1965), namely, that the typicality of an object in a conjunction is equal to the minimum of that object's typicality in the constituents (e.g., an object's typicality as a brown apple cannot exceed its typicality as a brown or as an apple). We evaluated this “min rule” against the typicality ratings of naive subjects in two experiments. For each of numerous pictured objects, one group of subjects rated its typicality with respect to an adjective concept, a second group rated its typicality vis-à-vis a noun concept, and a third group rated its typicality with respect to the adjective-noun conjunction. In both studies, most objects were rated as more typical of the conjunction than of the noun. These findings violate not only the min rule but also other simple rules for relating typicality in a conjunction to typicalities in the constituents. As an alternative to seeking such rules, we argue for an approach to conceptual combination that starts with the prototype representations themselves. We illustrate one version of this approach in some detail, and show how it accounts for the major findings of the present experiments.     

Right hemispheric specialization for mental imagery: A review of the evidence

An implicit assumption in the literature on functional hemispheric asymmetry is that the right hemisphere plays a special role in mental imagery. Using a definition of mental imagery as quasi-perceptual experience, we draw distinctions among visual imagery, visual recognition memory, and visuospatial abilities. We then review the research literature to evaluate the hypothesis that mental imagery is a specialized function of the right cerebral hemisphere, and find that it receives little unambiguous support. Case reports of loss of imagery are no more frequent with right than with left unilateral brain damage. Systematic studies of brain-injured patients provide some support for the hypothesis, but are also consistent with the alternative hypothesis of bilateral representation of imagery. Commissurotomized patients report dreaming and being able to form visual images. Behavioral and psychophysiological studies of non-brain-injured patients either fail to provide evidence in favor of the hypothesis or can be interpreted as compatible with the alternate hypothesis of bilateral hemispheric involvement in imagery. We conclude that there is, presently, insufficient empirical basis for considering imagery a right hemispheric function. We then discuss implications of this conclusion for future research.
