Supervisor estimation of abilities required in jobs

The Minnesota Job Requirements Questionnaire (MJRQ) was developed and administered to supervisors of 11 selected jobs who rated the ability requirements of the job they supervised. The MJRQ represented each of nine GATB aptitudes by five items in a Likert-type format. MJRQ ratings were compared with expert ratings in the Dictionary of Occupational Titles (DOT) and Occupational Ability Patterns (OAPs) derived from administration of the General Aptitude Test Battery (GATB). Reliability of MJRQ ratings was shown by high Hoyt reliability coefficients. Comparison of mean ratings and variabilities of ratings by supervisors in a job showed construct validity for the MJRQ approach, as did intercorrelations of MJRQ ratings. OAPs derived from the MJRQ compared favorably with those derived from the GATB and DOT, showing promise for the parsimonious MJRQ approach to the development of OAPs.     

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.     

The Cult of Doctors: Harvey Cushing and the Religious Culture of Modern Medicine

Harvey Cushing had an extraordinary life in medicine as an innovative brain surgeon and a pivotal figure in the biomedical revolutions taking place at the turn of the twentieth century. Expressions of sincere devotion from Cushing’s patients often rely on distinctly religious language to capture the meaning and impact of the doctor in their lives. If these devotional sentiments from former patients were the only traces of religious meaning associated with the life of Cushing, they could easily be discounted as an all-too-common, and some might say particularly confused, infusion of personal spirituality into the realm of medicine and health. But these expressions of adoration and veneration may be only the proverbial tip of a deep, wide, and largely unseen religious iceberg. Cushing’s extraordinary accomplishments did inspire both patients and the public in this era, but it is proposed that his life is embedded in a much larger and more significant religious movement driving the cultural success and power of biomedical science: the cult of doctors. Gary Laderman, Ph.D., is a cultural historian who has written two books on death in America, Rest in Peace: A Cultural History of Death and the Funeral Home in Twentieth-Century America (Oxford UP, 2003) and The Sacred Remains: American Attitudes Toward Death, 1799–1883 (Yale UP, 1996). His PhD is in Religious Studies from the University of California, Santa Barbara. He is working on a new book project that explores the intersections of religion and medicine in the twentieth century. This is the first article from that project.

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.     

An assessment of cerebral dominance in language-disordered children via a time-sharing paradigm

A time-sharing paradigm was used to assess language lateralization in language-disordered and normal children aged 4–7 years. Several expressive language tasks as well as a vocal, but nonlinguistic, task were administered concurrently with unimanual finger tapping. Dependent variables were percent disruption scores and number of syllables produced per concurrent trial. All language concurrent tasks produced tapping reductions for both hands for both groups. This result contrasts to similar time-sharing studies claiming asymmetrical interference and hence language lateralization in children (N. White & M. Kinsbourne, 1980, Brain and Language, 10, 215–223; J. Obrzut, G. Hynd, A. Obrzut, & J. Leitgeb, 1980, Brain and Language, 11, 181–194). A multiple regression analysis revealed a significant interaction effect differentiating language-disordered from normal children. Normals exhibited a parallel response pattern for speech and tapping (both increased or decreased in rate) under all lateralization conditions. Language-disordered children exhibited an inverse response pattern (e.g., if speech output increased, tapping rate decreased) only under left-hemisphere time-sharing.     

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.
