II—Richard Cross

ABSTRACT Scotus's belief that any created substance can depend on the divine essence and/or divine persons as a subject requires him to abandon the plausible Aristotelian principle that there is no merely relational change. I argue that Scotus's various counterexamples to the principle can be rebutted. For reasons related to those that arise in Scotus's failed attempt to refute the principle, the principle also entails that properties cannot be universals.     

Nonword repetition in lexical decision: Support for two opposing processes

We tested and confirmed the hypothesis that the prior presentation of nonwords in lexical decision is the net result of two opposing processes: (1) a relatively fast inhibitory process based on global familiarity; and (2) a relatively slow facilitatory process based on the retrieval of specific episodic information. In three studies, we manipulated speed-stress to influence the balance between the two processes. Experiment 1 showed item-specific improvement for repeated nonwords in a standard “respond-when-ready” lexical decision task. Experiment 2 used a 400-ms deadline procedure and showed performance for nonwords to be unaffected by up to four prior presentations. In Experiment 3 we used a signal-to-respond procedure with variable time intervals and found negative repetition priming for repeated nonwords. These results can be accounted for by dual-process models of lexical decision (e.g., Balota & Chumbley, 1984; Balota & Spieler, 1999).     

Learning Consistent,Interactive, and Meaningful Task-Action Mappings: A Computational Model

Within the field of human-computer interaction, the study of the interaction between people and computers has revealed many phenomena. For example, highly interactive devices, such as the Apple Macintosh, are often easier to learn and use than keyboard-based devices such as Unix. Similarly, consistent interfaces are easier to learn and use than inconsistent ones. This article describes an integrated cognitive model designed to exhibit a range of these phenomena while learning task-action mappings: action sequences for achieving simple goals, such as opening a file in a word processor. The model, called TAL, is of a user who is familiar with the basic operations of a keyboard and mouse, but unfamiliar with the particular menu structures, words, and actions required to use the device. The model is constructed in Soar and employs a single set of architectural mechanisms. It exhibits behavior that captures human preference for consistent, interactive, and meaningful task-action mappings.     

Prediction of Health Patterns from General Appraisal,Attributions, Coping,and Trait Anxiety

We examined the relationships among general appraisal style, attributional style, trait anxiety, coping styles, and health status (i.e., depression, hostility, and flu-like symptoms) in a study for which we also examined the validity of a trait measure of general appraisal. Participants completed personality measures at the beginning of an academic semester, and health assessments at regular intervals throughout the semester. Consistent with our predictions, after removing the influence of neuroticism and attributional style, general appraisal style led to more negative, and less positive affect 2 weeks later, and to more stressful and threatening appraisals of a life event occurring 3 months later. Multiple regression techniques showed that as predicted, after controlling for baseline health general appraisal style and attributional style predicted hostility and flu-like symptoms, and attributional style also predicted depression. These effects were mediated by trait anxiety. We discuss why both negative general appraisal and attributional styles may be risk factors for ill health.     

An investigation of everyday prospective memory

Prospective memory, remembering to carry out one’s planned activities, was investigated using a naturalistic paradigm. Three experiments, with a total of 405 participants, were conducted. The goal was to demonstrate that the cognitive processing underlying successful everyday prospective remembering involves components other than mere “memory.” Those components are probably best represented as individual differences in various cognitive capacities. More specifically, metamemory, attentional capacities, and planning processes that reprioritize intentions according to the demands of everyday life may determine how people actually accomplish the plans they establish for themselves. The results of these experiments suggest that researchers interested in the topic will have to contend with a multidimensional set of factors before any comprehensive understanding of prospective remembering can be realized.     

Fighting Igor: Exposing and Resisting the Irrational Side Using Cognitive-Behavioral Principles in Group Therapy

A visual cognitive behavioral framework developed, with indirect literature support, from the author's practice depicts a polarized conflict between a rational side and an irrational side, named Igor. Each side's characteristics, reasoning, and methods of dealing with thoughts, feelings, and behaviors in panic/phobic disorders are described. Techniques of a group therapy approach include members sharing symptoms, fears, and escape behaviors; the therapist providing corrective information and role playing of each side; and therapist/members monitoring and supporting behavioral homework. Outcome measures appear to support desired simplicity, palatability, efficiency, and effectiveness.     

Labeled Calculi and Finite-Valued Logics

A general class of labeled sequent calculi is investigated, and necessary and sufficient conditions are given for when such a calculus is sound and complete for a finite-valued logic if the labels are interpreted as sets of truth values (sets-as-signs). Furthermore, it is shown that any finite-valued logic can be given an axiomatization by such a labeled calculus using arbitrary "systems of signs," i.e., of sets of truth values, as labels. The number of labels needed is logarithmic in the number of truth values, and it is shown that this bound is tight.
