Are there still things to do in Bayesian statistics?

From the outside, Bayesian statistics may seem like a closed little corner of probability. Once a prior is specified you compute! From the inside the field is filled with problems, conceptual and otherwise. This paper surveys some of what remains to be done and gives examples of the work in progress via a Bayesian peek into Feller volume I.This work had its origin in conversations with Marco Scarsini. Distance has prevented us from working things out jointly. This paper was presented at the workshop, we thank Eugenio Regazzini, Dominico Costantini and Maria Carla Galavotti for their help. Art Dempster, Carl Morris, John Pratt, Abner Shimony and Sandy Zabell raised interesting questions incorporated herein.     

Anxiety and sensitivity to eye gaze in emotional faces

This paper reports three studies in which stronger orienting to perceived eye gaze direction was revealed when observers viewed faces showing fearful or angry, compared with happy or neutral, emotional expressions. Gaze-related spatial cueing effects to laterally presented fearful faces and centrally presented angry faces were also modulated by the anxiety level of participants, with high- but not low-state anxious individuals revealing enhanced shifts of attention. In contrast, both high- and low-state anxious individuals demonstrated enhanced orienting to averted gaze when viewing laterally presented angry faces. These results provide novel evidence for the rapid integration of facial expression and gaze direction information, and for the regulation of gaze-cued attention by both the emotion conveyed in the perceived face and the degree of anxiety experienced by the observer.     

Assigning Grammatical Gender During Word Production

The present study was designed to examine the processes by which grammatical gender is assigned during word production. French words varied in strength of sublexical cues, based on whether the word ending was typical for one gender rather than neutral about gender, and lexical cues, derived from the associated definite article being uninformative about gender for words beginning with a vowel, but informative for words beginning with a consonant. In Experiment 1, when native French speakers classified the gender of mentally evoked names of pictures, no effects of these cues were obtained. Experiment 2 used an improved methodology, with participants classifying the gender of words translated from English. English-speaking learners of French were influenced strongly by lexical and sublexical cues, while French speakers showed a weaker influence. However, for both speaker groups, words whose gender was classified slowly during recognition were also classified slowly during production, and error rates were similarly correlated across tasks. The conclusion was that gender is not equally available for all words once the associated “lemma” is accessed. Current models of language production may have to incorporate mechanisms allowing differential speed of access to gender information depending on a word’s formal properties.     

Six-year follow-up of three treatment programs to personality disorder

Previous studies of long-term outcome for personality disorder (PD) were either retrospective in design or did not include a control condition. In this paper we report results for three PD cohorts (N = 111) treated in two different specialist psychosocial programs (step-down and long-term inpatient) and in general psychiatric treatment as usual (TAU), which were prospectively followed up for 72-months after intake. The three PD samples were compared on symptom severity, social adjustment, global functioning and other clinical indicators (self-mutilation, parasuicide and readmission rates) at intake, 6, 12, 24, and 72 months. Results indicated that a specialist step-down model showed significantly greater change than a purely inpatient model and TAU in most key dimensions of functioning, a difference maintained at 72-months follow-up. Improvement in the samples was not associated with amount of intercurrent treatment received in the year prior to the follow-up assessment. This study confirms that a step-down program retains significant improvement associated with a specialist psychosocial approach for PD. However, this conclusion should be qualified by design limitations. The samples were not randomly allocated to the three conditions and the naturalistic geographical allocation used in the study created a potential for a number of confounds. Whilst we used extensive statistical controls, the possibility that the differences found between the groups may be due to population differences cannot be discounted.     

A smart unconscious? Procedural origins of automatic partner attitudes in marriage

The paper examines potential origins of automatic (i.e., unconscious) attitudes toward one’s marital partner. It tests the hypothesis that early experiences in conflict-of-interest situations predict one’s later automatic inclination to approach (or avoid) the partner. A longitudinal study linked daily experiences in conflict-of-interest situations in the initial months of new marriages to automatic evaluations of the partner assessed four years later using the Implicit Associations Test. The results revealed that partners who were initially (1) treated less responsively and (2) evidenced more self-protective and less connectedness-promoting “if-then” contingencies in their thoughts and behavior later evidenced less positive automatic partner attitudes. However, these factors did not predict changes in love, satisfaction, or explicit beliefs about the partner. The findings hint at the existence of a “smart” relationship unconscious that captures behavioral realities conscious reflection can miss.     

Governing therapy choices: Power/Knowledge in the treatment of progressive renal failure

This article outlines the struggle between the power of the health care professional and the rights of the individual to choose freely a modality of treatment. Nurses are instrumental in assisting patients in making the best decision for a therapy they will have to assume for the rest of their lives. In guiding patients' decision, nurses must take into account these unavoidable contingencies: changes in lifestyle, nutritional restrictions, level of acceptance, compliance issues, ease of training and availability of support/facilities. Ensuring that the patient makes an informed decision is therefore an ongoing challenge for nurses as they are taking part in a delicate balancing act between not directly influencing the patient's decision while making sure the patient is accurately informed.     

Reflecting on imagery: A clinical perspective and overview of the special issue of Memory on mental imagery and memory in psychopathology

The authors provide an overview of the papers in the special issue of Memory on mental imagery and memory in psychopathology. The papers address emotional, intrusive mental imagery across a range of psychological disorders including post‐traumatic stress disorder (PTSD), agoraphobia, body dysmorphic disorder, mood disorders, and psychosis. They include work on information processing issues including modelling cravings, conditioning, and aversions, as well as imagery qualities such as vividness and emotionality. The overview aims to place the articles in a broader context and draw out some exciting implications of this novel work. It provides a clinical context to the recent growth in this area from a cognitive behavioural therapy (CBT) perspective. We begin with PTSD, and consider links to imagery in other disorders. The clinical implications stemming from this empirical work and from autobiographical memory theory are discussed. These include consideration of a variety of techniques for eliminating troublesome imagery, and creating healthy, realistic alternatives.     

Tom Thumb in hospital: The fairy tale workshop in a paediatric oncology and haematology ward

Abstract

Definitions of and attitudes towards countertransference have changed throughout the twentieth century. From being seen as a contaminant in the analytical process, countertransference has come to be seen by many therapists as a potentially useful source of information about a client and his or her problems. There are dangers as well as benefits associated with analysis and utilization of countertransference. This article reviews these issues and proposes some guidelines that therapists may find useful when contemplating their countertransference reactions to clients, and when considering how best to utilize these.     

Disturbances of consciousness in dementia with Lewy bodies associated with alteration in nicotinic receptor binding in the temporal cortex

Disturbances of consciousness, including fluctuations in attention and awareness, are a common and clinically important symptom in dementia with Lewy bodies (DLB). In the present study we investigate potential mechanisms of such disturbances of consciousness (DOC) in a clinicopathological study evaluating specific components of the cholinergic system. [3H]Epibatidine binding to the high-affinity nicotinic receptor in the temporal cortex (Brodmann's areas 20 and 36) differentiated DLB cases with and without DOC, being 62-66% higher in those with DOC (F=4.5,p=.025). The were no differences between DLB patients with or without DOC in 125I-labeled alpha-bungaratoxin binding to the low-affinity nicotinic receptor, [3H]pirenzepine binding to the muscarinic M1 receptor, or in choline acetyltransferase activity. These findings provide support for the hypothesis that cholinergic activity is an important neural correlate if consciousness and suggest a mechanism of DOC in DLB involving alterations in the nicotinic receptor, composed of predominantly alpha4 and beta2 subunits.
