Classroom behavior inventory: Factor verification

Sixty-nine second grade suburban children were rated by three teachers using a classroom behavior inventory. Factor analysis was performed to test the a priori structure of the instrument. The 18-item inventory was analyzed on three factors: Task-Oriented vs Distractibility, Extroversion vs Introversion, and Considerateness vs Hostility. The three factors loaded perfectly according to the a priori design. The need for further investigations concerning the reliability and a comparison of the rating scale with objective observations is indicated.

Likelihoodism,Bayesianism, and relational confirmation

Likelihoodists and Bayesians seem to have a fundamental disagreement about the proper probabilistic explication of relational (or contrastive) conceptions of evidential support (or confirmation). In this paper, I will survey some recent arguments and results in this area, with an eye toward pinpointing the nexus of the dispute. This will lead, first, to an important shift in the way the debate has been couched, and, second, to an alternative explication of relational support, which is in some sense a “middle way” between Likelihoodism and Bayesianism. In the process, I will propose some new work for an old probability puzzle: the “Monty Hall” problem. Thanks to the participants of the Philosophy, Probability, and Modeling (PPM) Seminar at the University of Konstanz (especially Stephan Hartmann, Franz Huber, Wolfgang Spohn, and Teddy Seidenfeld), for a very fruitful discussion of an early draft of this paper in July, 2004. Since then, discussions and correspondences with Prasanta Bandyopadhyay, Luc Bovens, Alan Hájek, Jim Hawthorne, Jim Joyce, Jon Kvanvig (and other participants of his “Certain Doubts” blog, which had a thread on a previous draft of this paper), Patrick Maher, Sherri Roush, Richard Royall, Elliott Sober, Dan Steel, and an anonymous referee of Synthese has been very valuable.     

Hemisphere functioning and motor imitation in autistic persons

Previous research has found that a high proportion of autistic individuals exhibit an atypical pattern of hemispheric specialization suggestive of impaired left hemisphere functioning: namely, right hemisphere dominance for both verbal and visual-spatial processing. Studies of brain-damaged persons have suggested that the left hemisphere is specialized for the use of nonverbal gesture. Since a major characteristic of autism is an impairment in the use of gesture, it was predicted that autistic persons would also show atypical hemispheric specialization for motor imitation. To test this hypothesis, hemispheric activation was measured using EEG recordings of alpha rhythm in autistic and matched normal control subjects during four motor imitation tasks. Autistic subjects showed significantly greater right hemisphere activation during the imitation tasks, than normal subjects. This pattern was particularly evident in younger autistic subjects and during oral, rather than manual, imitation tasks.     

Applied developmental psychology: Problems and prospects for an emerging discipline

Some problems and prospects for the emerging discipline of applied developmental psychology are analyzed. A working definition of applied developmental psychology is offered, along with a categorization scheme which places developmental psychologists along the basic-applied continuum. Some of the tasks that applied developmentalists can perform are listed, followed by a discussion of the boundaries of applied developmental, particularly the boundary with clinical psychology. Next, the training of applied developmental psychologists at the predoctoral and postdoctoral levels is explored. Finally, some of the professional issues that might confront applied developmentalists as the field evolves are described.     

Moral judgment: Theory and research on differences between males and females

That men and women differ in their moral orientations is a commonly held stereotype. The view that men are morally superior can be found in the writings of philosophers and psychologists (most notably Freud). Recently, Carol Gilligan (Harvard Educational Review, 1977, 47, 431–517) has entered this discussion bringing to it what she calls a “different [woman's] voice.” In this paper, the theory of an ethic of care is described and contrasted with Kohlberg's morality of justice. The empirical support for Gilligan's claim that men and women differ in their moral orientations is examined and a discussion of Gilligan's contribution to an integrated theory of morality is offered.     

The effects of a career course on undecided college students

The effects of a career course taught by 11 instructors (two sections each) for college students, who were undecided about a major field or career, were evaluated in a pre-post design using the Vocational Identity, Occupational Information, and Barrier scales of the My Vocational Situation (J. A. Holland, D. C. Daiger, & P. G. Power, Palo Alto, Calif.: Consulting Psychologists Press, 1980). Large main effects were observed for the Identity and Occupational Information scales, but not for the Barriers scale. No interactions by instructor or student characteristics were found by using a simple ANOVA procedure or by using a split plot factorial design. The implications for new research and career instructors were discussed.
