A rule-based expert system for music perception

We describe an expert system written in Pascal to simulate part of Lerdahl and Jackendoff’s (1983) theory of music perception. This program, a production system based on a Hearsay II architecture (Nii, 1986), illustrates a number of techniques, including program modularity, complex data structures, and simulated parallelism using operating system concepts.     

CLINICAL EVALUATION OF THE SELF-INJURIOUS BEHAVIOR INHIBITING SYSTEM (SIBIS)

Five cases involving the treatment of longstanding, severe, and previously unmanageable self-injurious behavior are presented. In each case, the behavior was forceful contact with the head or face, and treatment consisted of mild and brief contingent electrical stimulation, delivered automatically or by a therapist, via the Self-Injurious Behavior Inhibiting System. Results of reversal and/or multiple baseline designs, in which sessions ranged in duration from 10 min to all day across a variety of settings, showed that the effects of the system were immediate and produced almost complete elimination of the self-injurious behavior. Controlled and anecdotal follow-up data for four of the five cases suggest continuing benefits and the absence of detrimental side effects associated with treatment. Potential applications of the device, as well as extensions and limitations, are discussed.     

Einstein and Duhem

Pierre Duhem's often unrecognized influence on twentieth-century philosophy of science is illustrated by an analysis of his significant if also largely unrecognized influence on Albert Einstein. Einstein's first acquaintance with Duhem's La Théorie physique, son objet et sa structure around 1909 is strongly suggested by his close personal and professional relationship with Duhem's German translator, Friedrich Adler. The central role of a Duhemian holistic, underdeterminationist variety of conventionalism in Einstein's thought is examined at length, with special emphasis on Einstein's deployment of Duhemian arguments in his debates with neo-Kantian interpreters of relativity and in his critique of the empiricist doctrines of theory testing advanced by Schlick, Reichenbach, and Carnap. Most striking is Einstein's 1949 criticism of the verificationist conception of meaning from a holistic point of view, anticipating by two years the rather similar, but more famous criticism advanced independently by Quine in Two Dogmas of Empiricism.I wish to thank the Hebrew University of Jerusalem, which holds the copyright, for permission to quote from the unpublished letters of Einstein.

A detector of sonic and ultrasonic vocalizations with frequency readout

An electronic apparatus to detect vocalizations between 4 and 50 kHz and to provide frequency readout is described. A frequency-to-voltage converter changes vocalizations to their analog. A peak-and-hold circuit retains and gates the maximal value of this analog voltage while it is accessed by a chart recorder or computer. Provision is made to lock out noise by inhibiting the device’s response to all signals lower than those associated with a selectable cutoff frequency. In preliminary tests of the apparatus, vocal signals of two rats in a common cage were recorded while the animals were subjected to a brief, intermittent bout of faradic shock to the feet. All recorded vocalizations occurred at frequencies below 26 kHz.     

Unemployed and exhausted? Job-search fatigue and reemployment quality

Job loss and job search are particularly devastating and stressful events that individuals can experience in their careers. However, less research attention has been paid to fatigue or burnout in the context of unemployment and job search. Drawing from Conservation of Resources theory, this study highlights the role that fatigue plays during unemployment and job search among displaced employees — defined as individuals who have lost their jobs involuntarily and are currently not engaged in any form of paid employment. In a two-wave longitudinal study involving 89 displaced employees, we illustrate how financial difficulties and social exclusion can lead to job search fatigue, while psychological capital serves as a personal resource that reduces job seekers' fatigue. We also demonstrate how job search fatigue at Time 1 can lead to lower reemployment quality at Time 2, which, in turn, can lead to lower organizational commitment and increased turnover intentions. Our findings bring into attention the important role that fatigue can play in the context of unemployment and job search.     

Relative Clause Attachment: Nondeterminism in Japanese Parsing

Like many other languages, Japanese is ambiguous about the potential attachment sites of a relative clause which appears alongside a complex noun phrase. One important class of parsing theories (nondeterministic accounts) predicts that the relative clause will initially be attached to the first available host and later assigned to an alternative site, following the intervention of certain discourse processes. An alternative (deterministic) account maintains that the preliminary attachment site remains unchanged throughout the course of processing the sentence. The results of a questionnaire and a self-paced reading study with Japanese materials of this kind provided evidence of phased attachment first to one noun host and then to another. It is argued that these results are compatible only with nondeterministic accounts of parsing.     

Operationalization of the Multicultural Counseling Competencies

For the past 20 years, the Association for Multicultural Counseling and Development (AMCD) has provided leadership for the American counseling profession in major sociocultural and sociopolitical domains. Through our vision of the centrality of culture and multiculturalism to the counseling profession, we have created new directions and paradigms for change. One of our major contributions has been the development of the Multicultural Counseling Competencies (Sue, Arredondo, & McDavis, 1992).     

Beauty is as Beauty Does?: Makeup and Posture Effects on Physical Attractiveness Judgments1

Recent studies have examined human beauty as a biological, structural trait. This view of beauty is incomplete because it does not consider the amount of variability in beauty judgments attributable to self-presentation strategies. This study was designed to estimate the importance of self-presentation practices on beauty judgments. For women within plus or minus one standard deviation of average facial attractiveness, makeup effect size estimates were comparable to previously published estimates of the importance of structural factors in attractiveness judgments. Similarly, for average weight stimuli, posture was comparable to body build in influencing attractiveness judgments. Implications for personal appearance businesses, health psychology, and counseling practice are discussed.     

The recovered/false memory debate: Three stepsforward, two steps back?

Although there are indications that opposing claimsabout the effects of childhood sexual abuse uponmemory have moderated over the last decade, thisdebate continues in an altered form: comparisons ofthe accuracy of continuous and non-continuous memoriesand the distinctions drawn between different forms ofamnesia have taken centre stage. Non-continuousmemories appear to have replaced ``repressed'memories and have been rendered pathological. It isargued that before expert evidence can go beyond thepresentation of these adversarial points of view inthe courtroom, resolution and understanding of theconcepts of amnesia and recovered memory experienceare required.     

Rule learning in rats: serial tracking in interleaved patterns

Humans have the ability to chunk together information from nonadjacent serial positions in sequential patterns. For example, human subjects can extrapolate the pattern, A-M-B-N-C-O-D-P-E-..., to find the missing element, Q, by sorting pattern elements into two component interleaved subpatterns: A-B-C-D-E and M-N-O-P-... Two experiments investigated the ability of rats to reorganize pattern elements from nonadjacent serial positions into chunks not presented by the experimenter. Rats learned either a structured or unstructured sequence interleaved with elements of a repeating sequence (experiment 1) or an alternation sequence (experiment 2). In both experiments, rats learned the interleaved subpatterns at different rates. Acquisition rate was correlated with the structural properties of component subpatterns and the nature of the rules required to describe the interleaved subpatterns. The results indicate that rats are sensitive to the organization of nonadjacent elements in serial patterns and that they can detect and sort structural relationships in interleaved patterns.
