Transparent layer constancy

Perceived transparency was studied as a constancy problem. In the episcotister (E-) model of scission, luminances are partitioned into layer and background components; four luminances determine values of two layer parameters that specify constancy of a transparent layer on different backgrounds. The E-model was tested in an experiment in which 12 Ss matched 24 pairs of four-luminance patterns by adjusting two luminances of the comparison pattern. Both the standard and the comparison were perceived as a transparent layer on a checkerboard. The E-model predicts matches when layer values are identical in the two patterns. One parameter was constant, constraining the adjustment along the second dimension. Obtained values corresponded well with E-predictions. Alternative models based on local luminance or average contrast ratios accounted for less variability. Results indicate that transparency models should utilize luminance, not reflectance, as the independent variable.     

Ms. and the manager: A tale of two stereotypes

Recent research on the Ms. stereotype suggests a potentially important exception to the strong link between gender and managerial stereotypes observed in the 1970s. Specifically, we hypothesized that a woman who prefers “Ms.” as her title of address would be seen by perceivers of both sexes as more similar in the “requisite” traits of a successful, middle manager than would a woman who prefers a traditional title of address for herself. These hypotheses were tested by having respondents rate a “successful, middle manager” or other stimulus persons varying in titles of address, sex, and marital status. Correlational analyses of respondents' ratings of stimulus persons yielded strong support for the hypotheses. That is, a woman preferring Ms. as her title of address was seen by adult perceivers of both sexes as possessing the “requisite” personality characteristics of a successful, middle manager; whereas a traditionally titled woman was not. Implications of these findings are discussed.     

Overt responding in computer-based training

This experiment compared the extent to which students learned facts included in computer-based-training frames that required an overt response to those that did not. Frames included two types of facts: Some facts had one word missing which had to be supplied by the student (active facts). Other facts had no missing words and required no overt response (passive facts). Each student completed four 14-fact modules in random order. Two of the modules contained frames with all active facts. Each frame in the other two modules contained one active and six passive facts. Paper pretests and posttests showed that students learned twice as many facts when all facts in the module were active than when only one in seven were active. The modules that included passive facts required one-fifth the time to complete than those with only active facts. Students learned more facts per minute of training in one of the two modules that included passive facts than in the two modules with only active facts.     

Differences in Personality Disorders and Family-of-Origin Characteristics for Male and Female Alcoholics: Implications for Treatment

This study investigated the personality and family-of-origin differences in male and female alcoholics. Results indicated that, regarding personality, men (both type 1 and type 2) were less troubled than were women. Implications for treatment based on these results are included.     

Mini-Review; Stress Genes: An Introductory Overview

Molecular sequence data, made available in the last 15 years or so, have led to the classification of living cells into three phylogenetic domains: Bacteria, Archaea, and Eucarya. All the organisms that have been tested belonging to either domain were capable of mounting a stress response with essentially the same characteristics, regardless of the stressor. The protagonists in the cell's stress response are the stress genes and their protein products. Some of the latter are molecular chaperones. Under physiological conditions, these chaperones aid other cellular proteins to fold properly and achieve a native -functional- configuration, and to translocate from the place of synthesis to the cell's locale in which they will operate. In a stressed cell, the stress proteins that are chaperones protect other molecules from denaturation and help those partially damaged to regain a functional configuration. Thus, cell death is avoided and recovery is enhanced. The study of stress genes and proteins has progressed considerably in organisms belonging to the domains Bacteria and Eucarya. Less is known about the archaeal stress genes. Here, research with an organism from the Archaea is discussed, focusing on the stress genes of the hsp70 (dnaK) locus. Future perspectives for basic and applied research within the health sciences and biotechnology industries are presented.     

Measurement and the interpretation of quantum mechanics and relativity theory

The axiomatic approaches of quantum mechanics and relativity theory are compared with approaches in which the theories are thought to describe readings of certain measurement operations. The usual axioms are shown to correspond with classes of ideal measurements. The necessity is discussed of generalizing the formalisms of both quantum mechanics and relativity theory so as to encompass more realistic nonideal measurements. It is argued that this generalization favours an empiricist interpretation of the mathematical formalisms over a realist one.     

Stories for therapy: The right story to the right person at the right time

In the postmodern information era with its increasing complexity and demands on my time, I find storytelling increasingly attractive. The right story told to the right person(s) at the right time in the right way can powerfully define and shape both individuals and the systems into which they organize themselves. As interventions go, I find stories to be relatively high impact, low-risk, parsimonious, and user-friendly. This paper contains some of my favorite teaching stories and describes why and how I use them as both a family therapist and teacher of family therapy.     

The self-narrative and acute psychosis

The aim of this study was to apply the narrative approach in analyzing family therapy meetings in cases of acute psychosis. The self-narrative is essential in acute psychosis since it is either collapsed or not coherent enough. The results indicate that it is important to create concrete practices that produce stories concerning the patient in relation to others. The self-narrative must be re-authored by the patient even though it is socially constructed. This is achieved by creating multiple perspectives of self-narratives in so-called therapy meetings with the patient, family members, and staff members representing different professionals.     

“Not with me you don't”: A story of narrative practice and dissociative disorder

This paper discusses issues relating to therapeutic practice based upon the narrative metaphor. A case of someone suffering the effects of Dissociative Identity disorder is used to illustrate the difficulties that clients can experience with the “expert” knowledge conception of therapy. The value of the “respectful” and “non-expert” emphasis of Narrative Practice emerges even when the therapist believes that he or she lacks expertise in the client's apparent “condition.” Three themes emanating from the case form the basis for the discussion: the client's experience of being recruited into accepting the diagnostic label of Dissociative Identity Disorder; the effects of being forced to accept a contract to eliminate self-abusive behaviour; and the therapist's dealing with a gun in the therapy room.
