Can shape be perceived by dynamic touch?

The possibility that some aspects of the shapes of solid objects can be perceived through dynamic touch, even when the objects are not touched, but simply wielded with a handle, was investigated in four experiments. Wooden solids were constructed of three sizes and five shapes: hemisphere, cylinder, parallelepiped, cone, and pyramid. Experiments 1 and 2 involved comparisons (judgments of same or different) between and among wielded objects of the same mass. In Experiments 3 and 4, subjects were required to wield an object and to select a match from a visible arrangement of objects of the five shapes; the wielded objects were of two sizes, each different from that of the visible objects. The success of subjects at these tasks, and the patternings of errors, are seen to involve the characteristic moment of inertia profiles of each shape, and a ratio of the object's resistances to rotation around orthogonal axes is shown to be a strong predictor of performance in the identification experiments. The results are discussed with reference to dynamic touch and to the notion of shape invariants that do not reduce to aspects of object surface.     

The patient-analyst match and the outcome of psychoanalysis: a pilot study

This paper presents a pilot study in which we explore the possibility that the match between analyst and analysand is a factor of central importance in the analytic situation. It is an attempt to look at the issue of match across a large number of patients. The data we used were not collected for studying this topic; thus, the study has serious limitations. Nevertheless, certain patterns emerged which support our thesis that patient-analyst match plays a significant role in the outcome of psychoanalysis. We present this work as a first step in developing concepts and methods which will be pursued in a more systematic and rigorous fashion in a later study.     

Dream frequency in psychoanalysis and psychoanalytic psychotherapy

The authors examine data on dream frequency from 50 patients, half of whom were seen in psychoanalysis and half in psychoanalytic psychotherapy. Frequency, defined as the proportion of sessions where at least one dream is related, is analyzed statistically as a function of sex, age, and type of treatment. Also, treatment outcome is examined as a function of sex, type of treatment, diagnosis, and dream frequency. Psychoanalytic patients are found to have higher dream frequency than the patients in the psychotherapy group. Higher average dream frequency is correlated with a better treatment outcome in both patient groups.     

Conflict Intensity,Family History,and Physiological Stress Reactions to Conflict Within Romantic Relationships

This study drew upon the physiological model of stress and desensitization processes to deduce hypotheses linking the intensity of conflict communication and exposure to familial verbal aggression in childhood to experiences of conflict within romantic relationships. One hundred college‐aged students (50 dating couples) participated in a dyadic interaction in which partners discussed a source of conflict in their romantic relationship. Participants reported childhood exposure to familial verbal aggression, third‐party observers rated the intensity of conflict communication, and salivary cortisol indexed physiological stress responses to the conflict interactions. As predicted, results showed a positive association between conflict intensity and cortisol reactivity, and this association was attenuated for individuals who reported higher, rather than lower, levels of childhood exposure to familial verbal aggression.     

Relational Turbulence Theory: Explaining Variation in Subjective Experiences and Communication Within Romantic Relationships

This essay extends the relational turbulence model as a framework for understanding communication in romantic relationships. Following the relational turbulence model, relational turbulence theory identifies relational uncertainty and interdependence as parameters that shape subjective experiences, but the theory clarifies the theoretical processes underlying their distinctive effects. In addition, relational turbulence theory articulates causal processes linking cognitive appraisals and emotions to communication. Relational turbulence theory also describes how episodes characterized by biased appraisals, intense emotions, and volatile communication coalesce into global evaluations of relationships as turbulent. In turn, the theory addresses the effect of relational turbulence on personal, relational, and social outcomes. Finally, the theory explains how communication can contribute to the development of both turbulence and resilience in romantic relationships.     

Explaining the Durable Effects of Verbal Person‐Centered Supportive Communication: Indirect Effects or Invisible Support?

Researchers have documented benefits from receiving supportive messages high in verbal person‐centeredness (VPC), but the processes through which such messages produce longitudinal effects remain unclear. This study evaluated two perspectives (i.e., indirect effects and invisible support) that address how supportive messages can produce durable effects and tested sex differences in those effects. 255 dyads completed a laboratory‐based interaction in which level of VPC and sex of the support provider were manipulated. 3 weeks later, support receivers evaluated the conversations and their stressor. Variations in VPC produced durable effects both when messages were positively evaluated initially and when they were evaluated as supportive by providers or third‐party observers but judged low in supportiveness by receivers. Provider sex moderated the results.     

Four Decades of Creative Vision: Insights from an Evaluation of the Future Problem Solving Program International (FPSPI)

E. Paul Torrance, a pioneer in creative education, and his associates founded the Future Problem Solving Program (now FPSPI, or Future Problem Solving Program International) in the mid‐1970s as a competitive, interscholastic program and as a curriculum project integrating creative problem‐solving and future studies. Since its founding, the program has emerged to be international in scope, and has expanded to incorporate multiple components to engage students’ creative strengths and talents in varied ways. This report presents highlights of an international evaluation of the program, the results of which support and sustain Torrance's creative vision for education.     

And so on . . . : reasoning with infinite diagrams

This paper presents examples of infinite diagrams (as well as infinite limits of finite diagrams) whose use is more or less essential for understanding and accepting various proofs in higher mathematics. The significance of these is discussed with respect to the thesis that every proof can be formalized, and a ??pre?? form of this thesis that every proof can be presented in everyday statements-only form.
