An information theory analysis of duration of lifeguards' scanning

Observers recorded the duration of scanning by six lifeguards in three indoor swimming pools. Duration of scanning was significantly predicted by the absolute numbers of child swimmers (< 17 years) in the pools and when numbers of child swimmers were represented in terms of bits of information. Duration of scanning increased as a linear function of both numbers of children and child bits of information. These results are interpreted in terms of the Hick-Hyman law of information theory. Lifeguards appear to simplify the task of information processing and decision-making by concentrating on children as a more at-risk group of swimmers. Duration of scanning was not significantly related to changes in number of adult swimmers.     

A Realist Analysis of the Relationship between Logic and Experience

I undertake to explain how the well known laws of formal logic – Barbara Syllogism, modus ponens, etc. – relate to experience by developing Edmund Husserl's critique ofFormalism and Psychologism in logical theory and then briefly explaining his positive views of the laws of logic. His view rests upon his understanding of the proposition as a complex, intentional property. The laws of formal logic are, on his view (and mine), statements about the truth values of propositions as determined by their formal character and relationships alone. The laws thus understood explain how algorithms set up to mirror them can accomplish what they do to advance knowledge, even though they operate purely mechanically. Further, they explain the proper sense in which formal laws "govern," and may guide, processes of actual thinking. Husserl's theory is a realist theory in the sense that, on his interpretation, the laws of pure or formal logic hold true regardless of what any individual, culture or species may or may not think, or even if no thinking ever occurs. This revised version was published online in June 2006 with corrections to the Cover Date.     

Representing the Structure of a Debate

In this article I aim to use the 1948 Russell-Copleston debate to highlight some recent problems I have experienced teaching argument analysis in my philosophy courses. First, I will use argument diagramming to represent the arguments in the debate while reflecting on the use of this approach use to teach argument analysis skills. Then, I will discuss the tools and methods scholars have proposed to represent debates, rather than just individual arguments. Finally, I will argue that there is not, but needs to be, a good way to represent argumentative debates in a way that neither obscures the essential details of the exchange nor becomes too unwieldy to extract a sense of the overall debate.

     

The Performance of Hamsters in the Maze Situation Utilizing Gravitation and the Vestibular Sense as Motivation

The hypotheses of this study of sex differences on a measure of self-esteem are as follows: 1) the scales good, nice, generous, pleasant, dependable, honest, and active will group together to form the outer esteem dimension of the semantic differential; 2) the scales strong, leader, powerful, confident, curious, inventive, sharp, and active will group together to form the inner esteem dimension of the semantic differential; 3) males will score significantly higher than females on the inner esteem dimension of the semantic differential; 4) females will score significantly higher than males on the outer esteem dimension of the semantic differential; 5) there will be a significant difference between the scoring patterns of males and females on the two dimensions of the semantic differential after controlling for the effects of race and social desirability. The sample of 442 sixth through eighth grade students consisted of two subsamples made heterogeneous on race, geographic location, and type of school. The Franks-Marolla Self-Esteem Semantic Differential and the Lunneborg and Lunneborg Child's Social Desirability Scale were administered. The findings support each of the hypotheses and indicate that there is a significant difference between the sexes on the Franks-Marolla Semantic Differential Measure of Self-Esteem. It is concluded that additional research in self-esteem might specify the meaning of sex differences in esteem by measuring esteem relative to an individual's structural social positions rather than measuring esteem in the general and environmentally nonspecific contexts as advocated by some.     

Substitution with Interrupted Tasks of Differing Valence

The study was designed (a) to develop a form of the Home Life Scale for university men, an instrument which provides a measure of perceptions of their home life in their families of orientation; and (b) to examine the perceptions of university men in relation to selected background characteristics and to their attitudes concerning father-son relationships. No significant relationships were observed between (a) home life perceptions and (6) age, marital status, father's occupation and education, source of family income, and socioeconomic status of parents; nor were any significant relationships observed between (a) attitudes concerning father-son relationships and (b) age, marital status, father's occupation and education, source of family income, and socioeconomic status of parents. How-ever, a significant relationship (p = .05) was observed between home life perceptions and attitudes concerning father-son relationships, indicating that those Ss who hold negative perceptions concerning their families of orientation reflected the most permissive attitudes concerning father-son relationships. Such a finding suggests that men who view their own families of orientation unfavorably may wish to create in their families of procreation a warmer, less restrictive atmosphere.
