Modal logic and model theory

We propose a first order modal logic, theQS4E-logic, obtained by adding to the well-known first order modal logicQS4 arigidity axiom schemas:A → □A, whereA denotes a basic formula. In this logic, thepossibility entails the possibility of extending a given classical first order model. This allows us to express some important concepts of classical model theory, such as existential completeness and the state of being infinitely generic, that are not expressibile in classical first order logic. Since they can be expressed in -logic, we are also induced to compare the expressive powers ofQS4E and . Some questions concerning the power of rigidity axiom are also examined.     

Is the Medium the Message? A Study of the Effects of Media,Communicator, and Message Characteristics on Attitude Change1

The present study examined the interactive effects of type of media, communicator, and position of message on persuasiveness of the communication. Subjects received a communication over television, radio (audio tape), or written medium, which either agreed with a position they held or strongly disagreed with it. The communicator was either a newscaster or a candidate for political office. The results indicated that subjects felt the newscaster to be more trustworthy than the candidate. In line with previous research, there was no main effect of media on persuasiveness. However, media interacted with the other variables so that when the communication disagreed with the audience, television was the most persuasive medium with the newscaster but the least persuasive with the untrusted candidate. There was no effect for media when the message agreed with the audience. Further, the candidate taking a position congruent with the audience's was rated as more attractive but less trustworthy than a candidate taking the opposite position. It was suggested that television may be the most involving medium and that either a counterargument theory or reactance theory could explain why it was not effective with the candidate.     

Children’s memory for sentences and word strings in relation to reading ability

A previous study of recall of letter strings by good and poor beginning readers IShankweiler, Liberman, Mark, Fowler, & Fischer, 1979 revealed that the performance of good readers was more severely penalized than that of poor readers when the letter names rhymed. To determine whether the differences in susceptibility to phonetic interference extend to materials that more closely resemble actual text, we designed an experiment to test recall of phonetically controlled sentences and word strings. As in the case of letter recall, we found that, although good readers made fewer errors than poor readers when sentences or word strings contained no rhyming words, they did not excel when the materials contained many rhyming words. In contrast to manipulations of phonetic content, systematic manipulations of meaningfulness and variations in syntactic structure did not differentially affect the two reading groups. We conclude that the poor readers’ inferior recall of phonetically nonconfusable sentences, word strings, and letter strings reflects failure to make full use of phonetic coding in working memory.     

Lateralness in women's work: New views on success

Data from a longitudinal study of postbaccalaureate nursing careers are discussed in the context of the motive-to-avoid-success controversy. Two groups of nurses with continuous work histories were intensively studied. While most had experienced upward professional mobility, a significant minority had lateral careers, which, though not characterized by advancement, typically provide rewards of intensification. Further, lateral careers only occurred in specialties allowing a high degree of professional autonomy. Thus, upward mobility and advancement should not be the sole criteria of women's occupational progress. Alternative conceptions of success may be significant in many occupations, although such beliefs may not serve as viable substitutes for professional autonomy and the opportunity for personal development. Lateral movement may also characterize most men's work lives more aptly than descent or ascent; hence the findings underscore the necessity to rethink the image of movement in both male and female work spheres.The research upon which this paper is based was supported by a grant from the Nursing Resources Division, USPHS (Grant NU-004-94-03) for the study of Post-Baccalaureate Careers in Nursing, Fred Davis and Virginia Olesen, Principal Investigators, Ellen Lewin, Assistant Project Director. This article was originally presented as a paper at the Pacific Sociological Association meetings, Sacramento, California, April 1977, where the panel commentator, Sheryl Ruzek, provided useful comments on the essay. Jane Tabata Usami provided a very helpful bibliographic search and other technical assistance.     

Edward Aloysius Pace

Summary Edward Aloysius Pace, pioneer of experimental psychology among American Catholics, was the first American Catholic and the first Catholic priest to study with Wilhelm Wundt. Upon his return from Leipzig, where he received his PhD in 1891, he established a psychological laboratory and department of psychology at the Catholic University of America in Washington, DC. This department became the model for most of the early departments of psychology at Catholic colleges and universities as well as the training center of many teachers who staffed the new departments at these Catholic colleges and universities. From Catholic University of America in Washington, DC, the experimental psychology of Wundt radiated to Catholic circles throughout the United States.The best account of Pace's life is to be found in Hart C (ed), Aspects of the New Scholastic Philosophy (New York: Benziger 1932, pp 1–9); a series of philosophical essays dedicated to Pace by the American Philosophical Association on the occasion of his seventieth birthday     

Analysis of factors influencing special educational placement decisions

To determine the factors that influence placement recommendations, 356 working school psychologists evaluated nine psychological reports on special educational referral cases. The reports presented various combinations of IQ-level, emotional-social problems, and IQ-achievement discrepancies which were hypothesized to yield EMR, LD, and ED placement recommendations. It was found that when one of these characteristics was present at a greater level of severity than the others, predictable placement recommendations were made. In more complex combinations, however, no general decision-rules could be found to explain the recommendations.     

Speech perception and memory coding in relation to reading ability

Previous work has demonstrated that children who are poor readers have short-term memory deficits in tasks in which the stimuli lend themselves to phonetic coding. The aim of the present study was to explore whether the poor readers' memory dificit may have its origin in perception with the encoding of the stimuli. Three experiments were conducted with third grade good and poor readers. As in earlier experiments, the poor readers were found to perform less well on recall of random word strings and to be less affected by the phonetic characteristics (rhyming or not rhyming) of the items (Experiment 1). In addition, the poor readers produced more errors of transposition (in the nonrhyming strings) than did the good readers, a further indication of the poor readers' problems with memory for order. The subjects were tested on two auditory perception tasks, one employing words (Experiment 2) and the other nonspeech environmental sounds (Experiment 3). Each was presented under two conditions: with a favorable signal-to-noise ratio and with masking. The poor readers made significantly more errors than the good readers when listening to speech in noise, but did not differ in perception of speech without noise or in perception of nonspeech environmental sounds, whether noise-masked or not. Together, the results of the perception studies suggest that poor readers have a perceptual difficulty that is specific to speech. It is suggested that the short-term memory deficits characteristic of poor readers may stem from material-specific problems of perceptual processing.     

Rounding Out the Cube: Evolution to a Global Model for Counseling Centers

This article discusses the present realities of college and university counseling centers as the bases for proposing a more adaptive and interactive model of the original Cube developed by W. H. Morrill, E, R. Oetting, and J. C. Hurst (1974). The article conceptualizes an evolved model of the Cube, here termed the global model, which allows counseling centers to function, in light of current and future demands, with greater flexibility, interdependency, and collaboration vis-á-vis the campus community.     

Predictors of cross-informant syndromes among children and youths referred for mental health services

This study sought to identify which syndromes of initial problems predicted later syndromes among children and youths referred for mental health services. Standardized parent reports on the Child Behavior Checklist obtained at intake were compared to standardized parent, teacher, and self-reports obtained at follow-up. There were 1,103 subjects (774 males and 329 females) 4 to 18 years old, followed up an average of 6 years after referral. High quantitative and categorical stability was found for cross-informant syndromes within samples of younger and older subjects. Throughout childhood and into young adulthood, parent ratings of most syndromes at the time of referral predicted the counterpart cross-informant syndrome construct at follow-up, controlling for other types of problems at referral. There were multiple additional independent predictors of many syndromes, including Delinquent Behavior, Aggressive Behavior, and Shows Off for young adult males. Time 1 Social Problems and Attention Problems independently predicted diverse problems at Time 2 for younger males. A wide variety of problems also predicted younger males' self-ratings of withdrawal, anxiety, and depression. The stability of problems for the referred sample was similar to that found for demographically matched nonreferred subjects drawn from a national sample.This work was supported by NIMH grants MH40305 and MH46093 and University Medical Education Associates, a nonprofit corporation of the University of Vermont College of Medicine.We are grateful to Edward Handy, M.S. for making available the records from the branch clinic.
