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.     

Personal and workgroup incivility: impact on work and health outcomes

This article develops a theoretical model of the impact of workplace incivility on employees' occupational and psychological well-being. In Study 1, the authors tested the model on 1,158 employees, finding that satisfaction with work and supervisors, as well as mental health, partially mediated effects of personal incivility on turnover intentions and physical health; this process did not vary by gender. Study 2 cross-validated and extended these results on an independent sample of 271 employees, showing negative effects of workgroup incivility that emerged over and above the impact of personal incivility. In both studies, all results held while controlling for general job stress. Implications for organizational science and practice are discussed.     

Recovery in memory function, and its relationship to academic success, at 24 months following pediatric TBI.

While a number of research papers have reported findings on memory deficits following traumatic brain injury (TBI), only limited studies have monitored the recovery of these skills over time. The present study examined memory ability and its effect on academic success in a group of children who had sustained a mild, moderate, or severe traumatic brain injury (TBI). Results showed that the severe TBI group exhibited greater deficits on memory tasks, irrespective of modality, in the acute, 6-, 12-, and 24-month postinjury stages, in comparison to mild and moderate TBI groups. Performance on academic measures was dependent on both injury severity and task demands. Preinjury academic ability and verbal memory indices best predicted academic success.     

Face processing: Human perception and principal components analysis

Principal components analysis (PCA) of face images is here related to subjects’ performance on the same images. In two experiments subjects were shown a set of faces and asked to rate them for distinctiveness. They were subsequently shown a superset of faces and asked to identify those that had appeared originally. Replicating previous work, we found that hits and false positives (FPs) did not correlate: Those faces easy to identify as being “seen” were unrelated to those faces easy to reject as being “unseen.” PCA was performed on three data sets: (1) face images with eye position standardized, (2) face images morphed to a standard template to remove shape information, and (3) the shape information from faces only. Analyses based on PCA of shape-free faces gave high predictions of FPs, whereas shape information itself contributed only to hits. Furthermore, whereas FPs were generally predictable from components early in the PCA, hits appeared to be accounted for by later components. We conclude that shape and “texture” (the image-based information remaining after morphing) may be used separately by the human face processing system, and that PCA of images offers a useful tool for understanding this system.
