Right-left confusion in the adult: A verbal labeling effect

Directional judgments are typically slower when relative location is described by the words “east” and “west” or “right” and “left” than when described by the words “north” and “south” or “up” and “down.” A series of experiments are reported that disentangle verbal from perceptual encoding explanations for right-left difficulty. Overall, our results support a verbal encoding explanation for right-left confusion in the adult. Experiments 1-3 demonstrate that in a response-differentiation task, it is response to the labels “north,” “east,” “south,” and “west” that is responsible for right-left confusion. In addition, Experiments 4-6 demonstrate that right-left difficulty in a mirror image discrimination task is contingent on the use of directional labels. (The data also suggest that it may be more difficult to deal with “up,” “down,” “left,” and “right” than with “north,” “south,” “east,” and “west”) The data are interpreted as inconsistent with a bilateral symmetry explanation for right-left confusion.     

On the {↔, ∼} -reduct of the intuitionistic consequence operation

The intuitionistic consequence operation restricted to the language with (equivalence) and (negation) as the only connectives is axiomatized by means of a finite set of sequential rules of inference.To the memory of Professor Roman Suszko     

The development of automatic word recognition and reading skill

The development of automatic word recognition as a function of reading skill was investigated in three experiments using the Stroop task. Reading skill level ranged from nonreaders to readers above the sixth-grade equivalent. Interference with color naming begins to emerge early in the process of learning to read, increases, and then subsequently decreases. Strings of identical letters delayed color naming for children just beginning to learn to read. The interference from words, presumably reflecting semantic processing, began developing early but did not peak until the second- to fourth-grade reading levels. These different sequences of development of interference in the various stimulus conditions suggest that word recognition is the result of a number of component processes that develop as children acquire skill in reading.     

Sensory experience and family process: perceptual styles tend to run in but not necessarily run families

The science of family systems has begun to develop concepts and methods for objectively assessing important characteristics of families. Thus we now have ways of measuring differences among families with respect to cohesiveness, flexibility, clarity of communication, and shared views of social reality. We know practically nothing, however, about the origins of these differences among families. One possibility is that the skills or personal attributes of one or more individual members influences the characteristics of the family as a whole. This paper explores the hypothesis that the perceptual styles of individual members--the ways they organize their experience of their personal stimulus world--influence the shared perceptions the family develops of the social world in which it lives. We explored relationships between nine measures of perceptual style and problem-solving measures of the family's shared perception of its social world. The findings showed many similarities among members of the same family on several measures of perceptual style. However, perceptual style had only a few relationships with family performance in the problem-solving task.     

Material, Myth, and Magic: A Cultural Approach to Family Therapy

This paper presents a model for a therapeutic approach to the cultural systems of families. Using anthropologically derived concepts of material and ideational planes of culture, magic, and ritualistic intervention, the inducement of culture change in frozen familial systems is framed in dialectical terms. Four brief case studies are presented describing the systems engaged, the material-ideational rituals employed, and the cultural transformations induced. The paper concludes with a brief discussion of some of the theoretical and practical implications of this cultural approach to the family in therapy.     

Contemporary Worldviews: Personal and Policy Implications12

In the past several decades, changes in industrial societies have presented a host of issues, worldwide in scope, around which individual attitudes may form: technological growth, population expansion, environmental quality, global resources, differing societal goals, etc. This study (N= 325) was conducted to identify and assess the major attitude/belief constellations surrounding these issues and to examine their psychological basis and implications for risk perception and societal decision-making procedures. Results supported the hypotheses that assessed contemporary worldviews are related in predictable ways to (a) the pexceived risk associated with selected technologies, (b) preferences for the manner in which societal decisions should be made, and (c) a coherent set of psychological variables. Discussion focuses on policy implications of differing contemporary worldviews and on future directions and applications of this line of research.     

Women,Education, Mathematics,and Computers: An Instance of Vocational Incongruence

A course in computer literacy was taken by 16 female elementary education majors specializing in mathematics. Results indicated that the students were dissimilar to the typical female college sample and to predicted occupational groups.     

An axiomatization of the ratio/difference representation

If ≥_r and ≥_d are two quaternary relations on an arbitrary set A, a ratio/difference representation for ≥_r and ≥_d is defined to be a function f that represents ≥_r as an ordering of numerical ratios and ≥_d as an ordering of numerical differences. Krantz, Luce, Suppes and Tversky (1971, Foundations of Measurement. New York, Academic Press) proposed an axiomatization of the ratio/difference representation, but their axiomatization contains an error. After describing a counterexample to their axiomatization, Theorem 1 of the present article shows that it actually implies a weaker result: if ≥_r and ≥_d are two quaternary retations satisfying the axiomatization proposed by Krantz et al. (1971), and if ≥_r′ and ≥_d′ are the relations that are inverse to ≥_r and ≥_d, respectively, then either there exists a ratio/difference representation for ≥_r and ≥_d, or there exists a ratio/difference representation for ≥_r′ and ≥_d′, but not both. Theorem 2 identifies a new condition which, when added to the axioms of Krantz et al. (1971), yields the existence of a ratio/difference representation for relations ≥_r and ≥_d.
