Phonology,reading, and Chomsky and Halle's optimal orthography

Chomsky and Halle claim that an orthography based on their underlying phonological representations (UPR) of lexical items would be optimal for English. This paper challenges three of C & H's basic phonological assumptions, that their vowel shift rule is valid, that the UPR is the only sound representation to be listed in the lexicon, and that derived words do not appear as wholes in the lexicon. A less abstract phonological representation level based on the conscious perceptions of speakers, the surface phonemic (SPR), is proposed. An SPR-based orthography has advantages which a UPR-based orthography would not: it is easy to learn and teach, it can be learned at an early age, and it permits rapid detection of rhyme. It is concluded that an orthography based on SPRs, and not UPRs, would be optimal.This research was supported in part by Office of Education contract OEC-9-71-0036(508), project 1-0527, to D.

The effects of confederate prompt delivery style in a standardized social simulation test

Role plays or social simulations are presently one of the most common methods for assessing social skills. Although social simulation techniques have become quite popular, little is known about the psychometric adequacy of many of the role-play instruments which have been developed. This investigation was an attempt to determine certain properties of one particular social skills assessment instrument: the Simulated Social Interaction Test. The effects of various confederate prompt delivery styles on the judged social competency level of subjects in the Simulated Social Interaction Test were examined. Two confederates, one male and one female, were trained to portray three confederate prompt delivery styles: (a) unreceptive, (b) neutral, and (c) receptive. In order to determine if judges would compensate for the different confederate prompt delivery styles, two sets of trained judges rated the levels of skill and anxiety generated by the 30 subjects tested. One set of judges was screened from the confererate delivery while observing the simulation; the other set of judges followed the more common rating procedure (i.e., they were not screened from the confederates' deliveries). Data analysis examined variation in subject performance under each condition and according to each set of judges for both overall social skills and anxiety ratings. Confederate prompt delivery style was found to affect subjects' rated performance. There was also suggestive evidence that judges were sometimes able to compensate for different confederate delivery styles. The practical and theoretical implications of the results are discussed.This study was funded in part by a research grant from the Veterans Administration.     

Effects of nitrous oxide on reactions to “stress”

It has been demonstrated that exposure to the stress of a situation involving conflict or frustration may interfere significantly with subsequent learning. Behaviour under stress is characterized by experiences of “anxiety” and by widespread physiological changes. Inhalation of nitrous oxide has the general effect of reducing the extent of these symptoms.

The present investigation using insoluble and soluble problems has demonstrated that both nitrous oxide and exposure to stress impair learning; but that, when subjects are exposed to stress while under the influence of the drug, the effects of the stress on subsequent learning are abolished. It is suggested that these empirical results may be accounted for either in terms of “anxiety-reduction” or in terms of transfer effects.     

Sex typing and the coronary-prone behavior pattern

The purpose of this study was to examine the relationship between sex-role orientation and the coronary-prone behavior pattern [Type A]. Ninety-six males and eighty-four females were administered the Bem Sex Role Inventory and the student version of the Jenkins Activity Survey. The results showed that, irrespective of sex, Type A subjects were significantly more instrumental (masculine) and less expressive (feminine) than Type B subjects. Consistent with previous research females were found to be more expressive than males; however, the sole predictor of instrumentality was A/B classification. The potential significance of these findings for refining predictions of coronary artery and heart disease is discussed and recommendations for future research are offered.Portions of this paper were presented at the Third Annual Meeting of the Society of Behavioral Medicine, Chicago, March 1982.     

Andisp: A Turbo pascal program to analyze and display sampled data

ANDISP is a Turbo Pascal program that analyzes, displays, and manipulates sampled data recorded with a PC-compatible data-acquisition system The data analysis routines include “integrate/differentiate a channel”, “rectify,” “smooth,” “filter,” and “add/sub/mult/div a channel by a constant, ” as well as a routine that gives some basic statistics. The data manipulation routines are “copy a channel” or “copy the data buffer to a file.” The versatile display routine can give either oscilloscope-type displays of a data channel or plots of pubUshable quality. Hardware requirements are an IBM-compatible microcomputer and an EGA color monitor.     

The influence of medical and legal authorities on deaths facilitated by physicians.

This study investigated whether two widely publicized cases of deaths facilitated by physicians were followed by significant peaks in mortality. In March, 1991, Timothy Quill, MD, published a controversial editorial describing the physician-assisted suicide (PAS) of his 45-year-old, female leukemia patient. In a landmark decision in December 1990, the Missouri Supreme Court allowed removal of life support for Nancy Cruzan, a comatose accident victim. Correcting for trends and seasonal fluctuations, the authors examined: (1) U.S. leukemia mortality in the period centered on Quill's editorial, and (2) mortality from accident/coma combinations in the period centered on the Missouri Supreme Court's decision on Cruzan. Female leukemia deaths rose 11.3% above the expected rate (p < .01) just after Quill's article was published. The more closely the decedent matched Quill's patient, the greater the peak, with the largest peak (33.9%) evident for female leukemia patients in their 40s, who were long-term residents of smaller communities (p < .05). Five possible explanations for the findings were assessed, leading to the conclusion that Quill's editorial elicited an increase in mortality. The involvement of physicians in this increase is supported by analysis of the Cruzan case. This showed a mortality peak of 57% for accident/coma patients following the court decision.
