An Appraisal Account of Individual Differences in Emotional Experience

People can differ tremendously in the emotions they experience, both in general as well as in response to specific events, and such differences have large impact on their lives. Based on recent research on individual differences in appraisal and emotion, we propose a framework to understand the basis for individual differences in emotional experience. In this framework, individual differences in how people appraise their circumstances and in how these appraisals are related to emotional experience are seen as crucial in determining how people differ in both contextualized emotional experience and more stable emotional dispositions. We discuss parallels with other explanatory frameworks, implications for the nature of emotion traits, and directions for future research.     

BETWEEN THE LINES OF AGE: REFLECTIONS ON THE METAPHYSICS OF WORDS

Abstract: The central concern of this paper is the nature of the relation between words on the one hand and their occurrences on the other. I argue here that while Kaplan's “common currency” conception of words is immune to much of the criticism to which Cappelen has subjected it, it runs afoul of the role words play in communication. And I sketch an alternative conception – the type‐continuant model – which shares the virtues but avoids the vices of Kaplan's conception.     

Are we aware of the external factors that influence our food intake?

OBJECTIVES: This research examines the extent to which people accurately report some of the external influences on their food intake. DESIGN: In two studies, specific factors (the presence and behavior of others) were manipulated in order to influence the amount of food that individuals consumed. MAIN OUTCOME MEASURES: The main outcomes of interest were participants' spontaneously generated explanations for their food intake (Study 1; n = 122), and their ratings of the importance of several potential determinants of food intake (Study 2; n = 75). RESULTS: In Study 1, there was high concordance between the amounts eaten by members of a dyad, but very few participants indicated that they were influenced by their partner's behavior; they instead identified hunger and taste as the primary determinants of intake. Study 2 showed that participants' intake was strongly influenced by the behavior of others, but people rated taste and hunger as much more important influences on their intake. CONCLUSIONS: If external environmental factors influence people's food intake without their awareness or acknowledgment, then maintaining a healthy diet can be a challenge, with long-term consequences for health and well-being.     

On the Validity of Simulating Stagewise Development by Means of PDP Networks: Application of Catastrophe Analysis and an Experimental Test of Rule-Like Network Performance

This article addresses the ability of Parallel Distributed Processing (PDP) networks to generate stagewise cognitive development in accordance with Piaget's theory of cognitive epigenesis. We carried out a replication study of the simulation experiments by McClelland (1989) and McClelland and Jenkins (1991) in which a PDP network learns to solve balance scale problems. In objective tests motivated from catastrophe theory, a mathematical theory of transitions in epigenetical systems, no evidence for stage transitions in network performance was found. It is concluded that PDP networks lack the ability to recover the positive outcomes of analogous catastrophe analyses of real cognitive developmental data. In an attempt to further characterize the learning behaviour of PDP networks, we carried out a second simulation study using the discrimination-shift paradigm. The results thus obtained indicate that PDP learning is compatible with the learning of stimulus-response relationships, not with the acquisition of mediating rules such as conceived in (neo-)Piagetian theory. In closing, we speculate about the feasibility of simulating stagewise development with alternative network architectures.     

Block's Overflow Argument

This article challenges Block's ‘overflow argument’ for the conclusion that phenomenal consciousness and access‐consciousness are distinct. It shows that the data can be explained just as well (or better) in terms of a distinction between contents that are made globally accessible through bottom–up sensory stimulation and those that are sustained and made available in working memory through top‐down attention.
