Imputation of missing categorical data by maximizing internal consistency

This paper suggests a method to supplant missing categorical data by reasonable replacements. These replacements will maximize the consistency of the completed data as measured by Guttman's squared correlation ratio. The text outlines a solution of the optimization problem, describes relationships with the relevant psychometric theory, and studies some properties of the method in detail. The main result is that the average correlation should be at least 0.50 before the method becomes practical. At that point, the technique gives reasonable results up to 10–15% missing data.We thank Anneke Bloemhoff of NIPG-TNO for compiling and making the Dutch Life Style Survey data available to use, and Chantal Houée and Thérèse Bardaine, IUT, Vannes, France, exchange students under the COMETT program of the EC, for computational assistance.

Three-space inference from two-space stimulation

Oblique contours sloping at 30° with respect to the horizontal were presented alone, in combination to form chevrons, or with a vertical line to form arrowhead or Y patterns; they were projected onto a screen in the frontal parallel plane and viewed from positions that gave viewing angles of 90° (normal to the screen’s surface), 53°, or 34°. The perceived orientation of the contours, as assessed by a movable arm that the subjects set to be parallel to the obliques, changed monotonically as a function of viewing angle. The change was as great for single obliques as for combinations of obliques within the chevron, arrowhead, and Y patterns. The results of Experiment 1 were extended in Experiment 2, in which obliques at 30° and 50° with respect to the horizontal were presented singly or in combination as chevron patterns. It is argued that the results of both experiments indicate that single two-space oblique lines are immediately interpreted as lying in three-space and that the changes in perceived orientation are a consequence of this perceptual inference.     

TREATING WOMEN AS SEX-OBJECTS

In this paper we have two related aims. First, we aim to present an account of what it is to treat women as sex-objects.¹ Like other philosophical writers in the field, we hold that the central idea in an account of such treatment is the failure to treat women with proper respect in sexual behavior. This idea has been cashed out in terms of using,² and in terms of dehumanization or failure to accord equal rights to freedom and welfare.³ However, we believe that there is a central deficiency in most such philosophical accounts of treating women as sex-objects, namely, a failure to outline in any detail a theory of interpersonal norms so that one can grasp in more concrete terms what it is to avoid treating a woman as a sex-object. We aim to rectify this deficiency by presenting a model of interpersonal norms based on the work of the social psychologist Chris Argyris.⁴     

Older men,older women: Are their perceived sex roles similar?

Men and women age 60 or older responded to Bem Sex-Role Inventory “masculinity” and “femininity” scale items on two separate administrations of the test. In the first, they described their own attributes; in the second, they described what others expected them to be like. Item analyses determined that the two sexes were more alike than different in sex-role-related attributes and perceived social expectation that they adopt both M and F attributes. Conflicts between actual and expected attributes were more frequent on “masculine” items. Those conflicted on “feminine” items tended to report depression.     

The effect of the two-chair dialogue intervention on self-compassion - adding an emotional evocative component to a basic Rogerian condition

Objective

How people relate to themselves when facing distress or failure influences general psychological well-being and vulnerability to psychological disorders. The aim of the present study was to explore the effect of an emotionally evocative intervention on self-compassion.

Methods

The data were retrieved from a larger study of Emotion-Focused Therapy (EFT) utilising a multiple baseline design comparing two treatment phases. The baseline phase consisted of 5, 7 or 9 therapy sessions where the therapist solely adhered to Rogerian relational conditions, as prescribed in EFT. A two-chair dialogue intervention was then added for five sessions. The sample consisted of 18 self-critical clients with clinically significant symptoms of depression and/or anxiety. The “Self-Compassion Scale” (SCS) was administered pre, mid and post therapy.

Results

The baseline phase did not lead to significant changes in self-compassion. However, the addition of the two-chair dialogue was associated with a significant increase in self-compassion. This increase was due to reductions in the negative subscales, especially the isolation subscale.

Conclusion

The emotionally evocative two-chair dialogue was associated with a significant change in self-to-self relating, compared to relational conditions alone. The two-chair dialogue, thus, seems to be a promising intervention for promoting healthier self-to-self relating.
