Working Memory Demands and Semantic Sensitivity for Prose in Mild Alzheimer's Disease

The debate continues with regard to whether degradation of semantic knowledge or deficits in information processing lead to impaired memory performance in patients with Alzheimer's disease (AD). This study examined the effects of semantic content and working memory demands on the recall and recognition abilities of patients with mild AD. Nineteen patients with probable AD and 19 demographically matched normal control participants were asked to remember prose passages that varied in semantic content (high, medium, and low level of idea importance) and working memory demands (narrative and expository passages). Compared to the controls, patients with mild AD lost the ability to recall prose in a manner consistent with the semantic structure of the passages as the demands on working memory increased. Furthermore, as the demands on working memory increased, patients recognized information in a manner that suggested their initial processing was of isolated details rather than by semantic structure. This study provides support for the hypothesis that information processing deficits contribute to impaired semantic processing in patients with mild AD.     

Investment in body image among patients diagnosed with or at risk for malignant melanoma

We examined investment in body image among 48 patients diagnosed with, or at risk for malignant melanoma (MM), as well as factors hypothesized as related to increased investment, such as gender, perceived stress, mood, fatigue, and personality characteristics. Investment in body image was evaluated using the Measure of Body Apperception [Carver, C. S., Pozo-Kaderman, C., Price, A. A., Noriega, V., Harris, S. D., Derhagopian, R. S., Robinson, D. S., & Moffat, F. L. Jr. (1998). Concern about aspects of body image and adjustment to early state breast cancer. Psychosomatic Medicine, 60, 168–174]. Results showed that women reported more concerns about physical appearance than men, and patients with MM exhibited more concerns about body integrity than at-risk patients. Concerns about body integrity were related to more compulsive personality characteristics, whereas concerns about appearance were associated with more histrionic personality characteristics. Body image investment was related to poorer adjustment as indicated by heightened symptoms of fatigue and stress. This study suggests that further research on investment in body image in this patient population is warranted.     

Family therapy for childhood depression: researching significant moments

This paper is a qualitative family therapy process study which is part of a larger European-based outcome study comparing family therapy to child psychotherapy plus parent support for depressed children and their families. The family therapists and two clinical supervisors from the original study formed themselves into a research team to study the process of therapy with twelve families. Therapists selected the significant moments from fifty-nine sessions, and were then interviewed by the research team using a standard protocol to investigate the therapists' own thinking about the significant moments. Applying a thematic analysis, the significant moments were clustered into eleven themes. The paper discusses the rationale for this model of research, which is well suited for clinical teams, and the application of the themes to therapeutic work with depressed children and their families.     

SIMPLIFIED HABIT REVERSAL TREATMENT FOR CHRONIC HAIR PULLING IN THREE ADOLESCENTS: A CLINICAL REPLICATION WITH DIRECT OBSERVATION

Three developmentally normal adolescents with chronic hair pulling were treated with a simplified habit reversal procedure consisting of awareness training, competing response training, and social support. Treatment resulted in an immediate reduction to near-zero levels of hair pulling, with one to three booster sessions required to maintain these levels. The results were maintained from 18 to 27 weeks posttreatment, although 1 participant reported difficulty at follow-up. The effectiveness of simplified habit reversal and suggestions for future research are discussed.     

Priorities in item recognition

The Sternberg paradigm was used to examine item recognition in the experiments reported here. Functions relating reaction time to positive set size and relating reaction time to the serial position of positive targets were discussed within the context of Sternberg’s (1969) recognition model. The experiments were designed to test (a) the hypothesis that certain members of the positive set receive preferential processing and (b) the hypothesis that some members of the negative set are compared to the target in memory. The results of both experiments supported the first hypothesis, and the results of Experiment I supported the second hypothesis. Models generally consistent with these results were discussed.     

From Pixels to People: A Model of Familiar Face Recognition

Research in face recognition has largely been divided between those projects concerned with front-end image processing and those projects concerned with memory for familiar people. These perceptual and cognitive programmes of research have proceeded in parallel, with only limited mutual influence. In this paper we present a model of human face recognition which combines both a perceptual and a cognitive component. The perceptual front-end is based on principal components analysis of face images, and the cognitive back-end is based on a simple interactive activation and competition architecture. We demonstrate that this model has a much wider predictive range than either perceptual or cognitive models alone, and we show that this type of combination is necessary in order to analyse some important effects in human face recognition. In sum, the model takes varying images of “known” faces and delivers information about these people.     

Beyond nomothetic classification of behavioural difficulties: Using Valued Outcomes Analysis to deal with the behaviour problems that occur in the classroom

The number of students who are labeled as having some form of behavioural disorder which requires specialized assistance in the regular school setting is growing. Current approaches to working with these students are often based on the standardized application of treatments designed to modify general symptoms rather than specific behaviours. It is noted that this approach to behaviour-change is limited because it does not seek to understand the reasons why particular behaviours are being used by students in particular settings. This paper will present an idiographic framework as an alternative approach to creating meaningful and long-term changes in the behavioural difficulties which occur in the school setting. This approach is based on developing a clear understanding of the purpose and usefulness of difficult student behaviour by investigating how that behaviour assists the student in gaining access to valued outcomes. Of particular significance to this assessment and intervention framework is the inclusion of the student's perceptions about the difficult behaviour and its impact on self, the environment and others. It is argued that effective changes in behaviour can only occur when the student's specific difficulties are understood and the student is taught specific skills to overcome these in the school setting.     

Sensitivity to interpersonal treatment in the workplace: Scale development and initial validation

The authors designed the sensitivity to interpersonal treatment (SIT) scale to assess how strongly individuals react to the interpersonal interactions in their workplaces. Questionnaire responses from 563 working undergraduates and 446 working adults provided data for this study. Details on the development of the new scale are provided along with initial evidence for its validity. Results indicated that the SIT is an internally consistent scale composed of two factors: self‐treatment and other‐treatment. Suggestions for future research that will develop a further understanding of SIT in the workplace are discussed.     

‘What made me unhappy’. Experiences of,and responses to,lifestyle changes in breast cancer patients

Sixteen breast cancer patients were interviewed about any lifestyle changes they had experienced and their reactions to those changes. Data were collected and analysed via content analysis and then summary tabulations of patient responses until replication of responses was verified across patients. Results indicated that most patients suffered a reduction in recreation activities, unpleasant physical side effects from treatment and loss of feminine appearance characteristics, all of which were seen as decreases in previously available and valuable sources of social support and self-esteem. In response to these losses, patients reported a common coping strategy of avoidance or escape similar to some depressive symptomatology. Implications for counsellors are discussed.     

Social problem‐solving skills as a mediator between executive function and long‐term social outcome following paediatric traumatic brain injury

There is debate regarding the relationship between executive function and social outcome following paediatric traumatic brain injury (TBI), due to inconsistent findings in the literature. It has been suggested that these contradictory results may reflect the absence of an established mechanism to explain this relationship. Yeates and colleagues (2004) proposed a possible model in which the maturity of social problem‐solving skills mediates the relationship between executive function and social outcome. The current study aimed to explore this model and determine whether social problem solving mediates the relationship between executive function and social outcome in a TBI population. The sample consisted of 36 adolescents and young adults who sustained a TBI between 8 and 12 years of age. They ranged between 16 and 22 years of age and were 7–10 years post‐injury. Findings indicated that a higher level of executive dysfunction was associated with less sophisticated social problem‐solving skills and poorer social outcome. Further, the maturity of social problem‐solving skills was found to mediate the relationship between executive function and social outcome in this group.
