Carnap and weyl on the foundations of geometry and relativity theory

An earlier version of this paper was presented at a workshop on Semantical Aspects of Space-Time Theories at the Zentrum für interdisziplinäre Forschung at the Universität Bielefeld in May 1994. I am indebted to the participants for helpful comments. I am also, and especially, indebted to comments from and discussions with Thomas Ryckman. All translations from the German are my own.     

Ego identity status in college women

Ego-identity status was determined for 49 college women and related to difficulty of college major, self-esteem, authoritarianism, and Welsh Anxiety Scale (WAS) scores The modified identity status interview for women included “attitudes toward premarital intercourse” Identity achievements had more difficult majors than identity diffusions Foreclosures were highest in self-esteem and lowest in WAS scores–interpreted either as approval-seeking or as this status's adaptive value for women. They were also highest in authoritarianism Moratoriums were lowest in authoritarianism. Identity diffusions obtained the highest WAS scores Failure to find differences on the Luchins Water Jars task was seen as limiting the range of the identity status constructs.     

EFFECTIVENESS OF A THREE-WEEK INSTITUTE FOR EMPLOYMENT SERVICE COUNSELORS

Forty-three employment service counselors participated in a three-week institute designed to improve their understanding of the conditions of poverty and of counseling theory and techniques. At the end of the institute, participants evaluated their experence favorably with substantial minority group criticisms, however, that (1) institute faculty were not sufficiently informed about Employment Service techniques and experiences and, that (2) not enough counseling practicum experiences were provided. Significant shifts in attitudes toward the poor were found at the end of the institute for 14 of 35 items of an attitude scale. For 6 of these 14 items, shifts in attitude were in the same direction and intensified after four and one-half months of field experience.     

Comparisons of some learning models for response bias in signal detection

The effects of variations in signal probability and varying degrees of correct feedback on response bias were studied in a yes-no auditory signal detection task. The main finding was that the bias towards saying yes was an increasing function of the frequency of signal feedback events, but did not depend on the correctness of the feedback. Several learning models coupled with a simple psychophysical and decision model yielded predictions about overall biases and certain sequential statistics. Only one model, which can be decribed as an “informational” model, gave a good account of both observed overall biases and sequential statistics. This model assumes the observer’s response bias is strengthened for the feedback-reinforced response when the observer’s sensory information is ambiguous or is contradicted by the feedback information.     

Impaired activation of the phonological lexicon: effects upon oral reading

The role of the phonological lexicon in oral reading is examined in a patient with a small focal left hemisphere lesion. Impaired access to the patient's phonological lexicon is suggested by a number of findings, including the production of phonemic errors across a variety of tasks; increasing difficulty in word production with increasing word length; and difficulty on tests of homophone and rhyme judgments. Two competing models of reading are tested: the nonlexical ("rules") and the lexical ("no-rules") models. The rules model predicts that a disturbance in the phonological lexicon will result in surface alexia; the no-rules model predicts phonological alexia. Results indicate that the patient's reading is most similar to phonological alexia, providing support for the no-rules model. The applicability of the no-rules model to other forms of acquired alexia is explored.
