The strength and generality of stimulus over-selectivity in simultaneous discrimination procedures

Stimulus over-selectivity refers to behavior being controlled by one element of the environment at the expense of other equally salient aspects of the environment. This is a common problem for many individuals, including those with autism spectrum disorders, and learning difficulties, and presents a considerable problem for information processing in many important situations involving complex cues and environments. Three experiments explored the strength and generality of the over-selectivity effect in non-clinical adults undertaking a cognitively demanding task, by training and testing participants on a two-component trial-and-error discrimination learning task. The over-selectivity effect was found in a variety of test conditions, including when the comparison test stimulus was neutral (Experiment 1), novel (Experiment 2), neutral with no conditioning history (Experiment 3), or when punished during training (Experiments 1, 2 and 3). Such results provide ubiquity to the phenomenon, making it important to investigate further.     

The effects of a concurrent task on human optimization and self control

Memory deficits have been shown to hamper decision making in a number of populations. In two experiments, participants were required to select one of three alternatives that varied in reinforcer amount and delay, and the effect of a concurrent task on a behavioral choice task that involved making either an impulsive, self-controlled, or optimal response was studied. The studies aimed to see whether or not individuals were capable of optimizing when confronted with a three-alternative choice paradigm, and if a concurrent task could induce over-selectivity toward a self-controlled, or impulsive, choice, rather than an optimal choice. Various factors which could possibly influence optimization were also explored. The results suggest that some, but not all, individuals are capable of optimizing in a three-alternative choice paradigm, especially when there is a great differential between reinforcement rates of optimal versus non-optimal behaviors. Participants with a concurrent task (continuously subtracting seven from a large number) displayed over-selectivity, evidenced by the high proportion of self-controlled responses.     

Narrative vignettes and online enquiry in researching therapist accounts of practice with children in schools: An analysis of the methodology

Aims: This article reviews a research methodology that uses an Internet mediated qualitative, narrative approach to provide in‐depth analysis of vignettes. The research sought to investigate the ways in which dramatherapists, based in different countries, understood the nature of therapeutic change in their work with children. Method: The article describes a qualitative approach to the generation of data by a combination of therapist‐authored vignettes, live, synchronous Internet mediated communication (aMSN Messenger) and email. Participants kept a diary of their response to the research and the article draws on this data within its analysis of the methodology. Findings: Samples of the data are used to analyse how such innovative, online methodology can develop effective access and relationships with geographically dispersed participants and as an effective way of investigating therapist practitioners' understanding of their practice.     

Aristotle on Predication

A predicate logic typically has a heterogeneous semantic theory. Subjects and predicates have distinct semantic roles: subjects refer; predicates characterize. A sentence expresses a truth if the object to which the subject refers is correctly characterized by the predicate. Traditional term logic, by contrast, has a homogeneous theory: both subjects and predicates refer; and a sentence is true if the subject and predicate name one and the same thing. In this paper, I will examine evidence for ascribing to Aristotle the view that subjects and predicates refer. If this is correct, then it seems that Aristotle, like the traditional term logician, problematically conflates predication and identity claims. I will argue that we can ascribe to Aristotle the view that both subjects and predicates refer, while holding that he would deny that a sentence is true just in case the subject and predicate name one and the same thing. In particular, I will argue that Aristotle's core semantic notion is not identity but the weaker relation of constitution. For example, the predication ‘All men are mortal’ expresses a true thought, in Aristotle's view, just in case the mereological sum of humans is a part of the mereological sum of mortals.     

Discontinuities in the male psyche: waiting, deadness and disembodiment. Archetypal and clinical approaches

The discontinuities of development in the male psyche that are manifested in some analyses in unconscious experiences of inner disintegration are described. Narcissism and a de-somatized relationship to their own presence are the dominant clinical presentation in these patients. The analyst sometimes experiences these analyses as 'dead', as a result of the projection of a 'dead mother' object. The question of how psychic deadness and impotence can be worked with is examined. Clinical experience with these men shows how notions associated with the puer-senex archetype can illuminate the stark realities of a patient's early experiences, particularly in how mother's presence is felt. A theoretical and clinical bridge is proposed between puer and narcissus to frame how a man may unconsciously strive against psychic fragmentation by clinging to an identification with both--in order to remain intact in the face of being caught in a pre-pubescent state which reflects the insecure attachment to mother. The author describes how patients may find a more grounded embrace of reality via the use of the analyst's empathy and a greater potency through work in the transference/countertransference. These strengthening achievements help men to begin to leave the 'dead mother' behind.     

A Preliminary Analysis of the Rorschach Records of Fifty Prison Inmates

An attempt was made to test the hypothesis that the Egocentricity Index (Exner, 1974), a ratio which incorporates pair and reflection responses, is related to self-esteem. Sixty criminal defendants referred for psychiatric evaluation were routinely administered the Rorschach. After all other testing was Completed the subjects were asked to complete the Coopersmith Self-esteem Inventory. Results found no significant relationships between the Egocentricity Index and self-esteem as measured by the Coopersmith. It was recommended that the Egocentricity Index not be used as a measure of self-esteem, until research evidence to support its use in this manner is provided.     

How Resilient Are Our Attempts to Explore the Mind of Another? Commentary on Dr. Karlen Lyons-Ruth's Article

This article discusses whether attachment experiences may shape the quality and consistency of individuals' attempts to explore the minds of significant others, a process Dr. Lyons-Ruth refers to as intersubjectivity. Specific commentary focuses on whether individuals with an insecure or disorganized attachment organization continue to engage in intersubjective processes over the lifespan. To help illuminate these questions, the work of the University College London group on reflective functioning is discussed and directions for future research are suggested.
