A Systems/Dialectical Model of Supervision: A Symbolic Process

Although there has been a proliferation of models of supervision in the marriage and family therapy literature recently, most tend to focus on methods rather than on the process of supervision. The model presented here is grounded in developmental concepts and focuses on student learning through a dialectical process of cognitive and emotional growth and incorporates three stages: 1) developing relationships; 2) breaking impasses, and 3) orchestrating changes. Students discover that supervision becomes isomorphic with relationship issues that arise in their therapy sessions. Dialectical in nature in that each stage is characterized by the resolution of contradictory emotions, the supervision process helps supervisees experience emotional shifts in their interactions with others, referred to as emotional restructuring.     

Knowledge level learning and the power law: A soar model of skill acquisition in scheduling

Zusammenfassung. Das hier vorgestellte Modell lernt graduell, Planungsaufgaben aus der Klasse der Maschinenbelegungsprobleme (job-shop-scheduling problems) zu lösen. Mit Hilfe des Chunking-Mechanismus von Soar wird episodisches Wissen über die Belegungsreihenfolge von Aufträgen auf Maschinen memoriert. Bei der Entwicklung des Modells wurden zahlreiche qualitative (z. B. Transfereffekte) und quantitative Befunde (z. B. Bearbeitungszeiten) aus einer früheren empirischen Untersuchung berücksichtigt. In einer Validierungsstudie wurden dieselben Aufgaben von 14 Probanden und dem Modell bearbeitet. Die Passung von Simulationsdaten und empirischen Ergebnissen fiel insgesamt gut aus. Allerdings löst das Modell die Aufgaben schneller und zeigt auch einen etwas besseren Lernverlauf als die Probanden. Das Modell liefert eine Erklärung für das Rauschen, das typischerweise bei Bearbeitungszeiten zu beobachten ist: es handelt sich um erworbenes Wissen, das mehr oder weniger gut und auch unterschiedlich häufig auf neue Situationen übertragen wird. Der Lernverlauf der Probanden entspricht nur für aggregierte Daten einer Potenzfunktion (power law). Der vorgestellte Mechanismus zeigt, wie ein symbolisches Modell der Informationsverarbeitung graduelle Verhaltensänderungen generiert und wie der offensichtliche Erwerb allgemeiner Prozeduren ohne explizites Lernen von deklarativen Regeln erfolgen kann. Es wird nahegelegt, daß es sich hier um die Modellierung einer Form impliziten Lernens handelt. Summary. The model presented here gradually learns how to perform a job-shop scheduling task. It uses Soar's chunking mechanism to acquire episodic memories about the order to schedule jobs. The model was based on many qualitative (e.g., transfer effects) and quantitative (e.g., solution time) regularities found in previously collected data. The model was tested with new data where scheduling tasks were given to the model and to 14 subjects. The model generally fit these data with the restrictions that the model performs the task (in simulated time) faster than the subjects, and its performance improves somewhat more quickly than the subjects' performance. The model provides an explanation of the noise typically found in problem solving times - it is the result of learning actual pieces of knowledge that transfer more or less to new situations but rarely by an average amount. Only when the data are averaged (i.e., over subjects) does the smooth power law appear. This mechanism demonstrates how symbolic models can exhibit a gradual change in behavior and how the apparent acquisition of general procedures can be performed without resorting to explicit declarative rule generation. We suggest that this may represent a type of implicit learning.     

The puzzle of language evolution

Linguistics must again concentrate on the evolutionary nature of language, so that language models are more realistic with respect to human natural languages and have a greater explanatory force. Multi-agent systems are proposed as a possible route to develop such evolutionary models and an example is given of a concrete experiment in the origins and evolution of word-meaning based on a multi-agent approach.     

Nonverbal Counting in Humans: The Psychophysics of Number Representation

In a nonverbal counting task derived from the animal literature, adult human subjects repeatedly attempted to produce target numbers of key presses at rates that made vocal or subvocal counting difficult or impossible. In a second task, they estimated the number of flashes in a rapid, randomly timed sequence. Congruent with the animal data, mean estimates in both tasks were proportional to target values, as was the variability in the estimates. Converging evidence makes it unlikely that subjects used verbal counting or time durations to perform these tasks. The results support the hypothesis that adult humans share with nonverbal animals a system for representing number by magnitudes that have scalar variability (a constant coefficient of variation). The mapping of numerical symbols to mental magnitudes provides a formal model of the underlying nonverbal meaning of the symbols (a model of numerical semantics).

Recent Developments in Close-Relationships Theory

A selective review of some recent theoretical developments in the field of close relationships is presented. We describe demographic developments reflecting flux in relationships and the family and what may be viewed as a revolution in gender relations and the family over the past three to four decades. Also reviewed are theories on the development, maintenance, and ending of relationships, as well as the “dark side" of closerelationships. We conclude that the close-relationships field is likely to continue to develop and prosper as people search for answers to daunting relationship problems.     

The Feeling-Tone Questionnaire: Reliability and Validity of a Direct Patient Assessment Screening Instrument for the Detection of Depressive Symptoms in Cases of Dementia

The purpose of this study was to develop a reliable and valid measure of affective disorder in elderly demented patients. The field lacks instruments which are sensitive to detecting depressive signs in severely as well as mildly and moderately demented subjects. Two samples of subjects were chosen for study. The first sample consisted of subjects from six institutions, which were chosen for study from a probability sample of 25 long-term care institutions in New York City. This sample was part of the Cross-National Institutional Study conducted in New York and London (Gurland et al., 1979; Mann et al., 1984). Thirty patients were selected at random within each institution. The second sample consisted of 52 inpatients at Willard Psychiatric Center, a traditional state psychiatric hospital in upstate New York. All subjects had a chart diagnosis of dementia and were 60 years old or older. The mean age of the sample was 82 years and 56% of the subjects were female. The Feeling-Tone Questionnaire, which was developed for these analyses, consists of 16 dichotomous items and 16 5-point Likert ratings of affect. The reliability of this scale using Cronbach's alpha is .91 for the long-term care institutional sample and .90 for the psychiatric hospital sample. Interrater reliability for two raters on ten cases is .99. Test–retest reliability on ten cases with a 1-day to 2-day interval between trials is .81. A short mood scale was developed from the observational data as a validity measure for the Feeling-Tone Questionnaire. Evidence for the validity of the Feeling-Tone Questionnaire is provided.     

Helps to Fostering Students' Spiritual Health [1]

Interviews with 98 teachers from a variety of schools were used to develop a definition of spiritual health, and to establish how these teachers thought spiritual health might best be fostered and what hindered its development in the school curriculum. A recurring theme, which seemed to be coming through the comments from teachers in this study, was the very important role that teachers play in helping students develop relationships. This was of vital importance as spiritual health was seen as being reflected in the quality of relationships that students develop with themselves, others, the environment, and with a Transcendent Other. The characteristics of teachers most frequently mentioned as desirable for the promotion of spiritual health were classified as follows:

? caring, sensitive, personal approach;

? concern for individuals;

? committed to personal beliefs and values.

Investigation of these teacher characteristics showed variation by gender, personal view of spiritual health, major curriculum concern, teacher and school type. Implications of these variations are discussed in this paper, together with the role of Spiritual Facilitator, to help nurture students' spiritual health.
