The obscure act of perception

Finding disjunctivist versions of direct realism unexplanatory, Mark Johnston [(2004). Philosophical Studies, 120, 113–183] offers a non-disjunctive version of direct realism in its place and gives a defense of this view from the problem of hallucination. I will attempt to clarify the view that he presents and then argue that, once clarified, it either does not escape the problem of hallucination or does not look much like direct realism.

Direct perception in the intersubjective context

This paper, in opposition to the standard theories of social cognition found in psychology and cognitive science, defends the idea that direct perception plays an important role in social cognition. The two dominant theories, theory theory (TT) and simulation theory (ST), both posit something more than a perceptual element as necessary for our ability to understand others, i.e., to “mindread” or “mentalize.” In contrast, certain phenomenological approaches depend heavily on the concept of perception and the idea that we have a direct perceptual grasp of the other person’s intentions, feelings, etc. This paper explains precisely what the notion of direct perception means, offers evidence from developmental studies, and proposes a non-simulationist interpretation of the neuroscience of mirror systems.     

Maternal verbal interaction in different situations with infants born prematurely or at term

The present study investigates whether maternal verbal behaviour, in terms of the use of declaratives, interrogatives and imperatives, can be accounted for by gestational age of the infant, or the situation in which mother–infant pairs were observed. Thirteen mothers and their premature and term babies were observed twice in three situations, namely playing with, feeding and changing their infants. The first observation took place at a mean gestational age of 40 weeks and the second observation took place approximately 7 weeks later. All mothers used more imperatives during play than during changing or feeding situations. Mothers used more interrogatives during play than during changing or feeding, and they used more declaratives during both changing and playing than during feeding. In contrast, gestational age influenced only the complexity of maternal interrogatives. It is concluded that situational factors are significant and hence that the mother's role has to be judged relative to the context in which mothers and infants are observed.

Comparison of two aggression inventories

Two recently developed questionnaire measures of aggression, the Aggression Questionnaire [Buss and Perry (1992; Journal of Personality and Social Psychology 63:452–459]; and the Aggression Inventory [Gladue (1991a); Psychological Reports 68:675–684], were administered to a British sample (N=320) of men and women undergraduates. Both questionnaires contain subscales measuring physical and verbal aggression; the other scales of the Aggression Questionnaire measure anger and hostility, and those of the Aggression Inventory measure impulsiveness and avoidance of aggression. The factor structure of scales were assessed using confirmatory factor analysis. The interrelations of the subscales were calculated in both cases: anger was independently related to verbal and physical aggression and to hostility on the Aggression Questionnaire; impulsivity, and verbal and physical aggression were associated on the Aggression Inventory. Sex differences were largest on the two physical subscales, of lesser magnitude but still significantly different for the two verbal subscales, but absent for anger and hostility. This supports the hypothesis that sex differences in aggression are larger for more escalated forms of aggression. The physical and verbal subscales of the two questionnaires were each highly correlated with one another and the impulsive subscale of the Aggression Inventory highly correlated with the anger subscale of the Aggresion Questionnaire. Thus, two aggression questionnaires developed in the US not only produce similar associations between subscales and sex differences among a British undergraduate sample, but also show high correlations between their respective scales. © 1995 Wiley-Liss, Inc.     

Numerical and verbal decision analysis: comparison on practical cases

Numerical decision analysis (NDA), derived from statistical decision theory, is very well known. Verbal decision analysis (VDA), oriented towards so‐called unstructured problems, where the qualitative and uncertain factors dominate, is a newer direction in decision theory and practice. Verbal and numerical decision analyses (DAs) have been compared in an experimental setting, with groups of students. This paper presents the results of a comparison in the context of live practical tasks. Both approaches were attempted on two comparable choices, facing both Russian and US government agencies, involving a choice between oil and gas transportation options. The resulting methodological insights are generalized into a systematic comparison of the strong and weak features of each approach. Copyright © 2000 John Wiley & Sons, Ltd.
