Synthesized clustering: A method for amalgamating alternative clustering bases with differential weighting of variables

In the application of clustering methods to real world data sets, two problems frequently arise: (a) how can the various contributory variables in a specific battery be weighted so as to enhance some cluster structure that may be present, and (b) how can various alternative batteries be combined to produce a single clustering that best incorporates each contributory set. A new method is proposed (SYNCLUS, SYNthesizedCLUStering) for dealing with these two problems.We wish to thank Anne Freeny and Deborah Art for their computer assistance, and Ed Fowlkes for his helpful technical discussion. We would also like to acknowledge the insightful and helpful comments from the editor and reviewers.     

The structure of workplace adaptive skill in a career inexperienced group

Adaptive skill is a central concept to understanding vocational behavior. In this study, a theory of behavioral functionality is proposed that describes the underlying structure of workplace adaptive skill. The propositions of the theory are formalized in a facet theory mapping sentence, then 12 adaptive skills are assessed on a group of career inexperienced individuals using a structured interview methodology. Smallest space analysis applied to the interview ratings reveals a three-dimensional structure of behavioral functionality. After refinements are made to the theoretical framework, we explore the implications of our findings for understanding the development of adaptive skills in the workplace and for contributing knowledge to the field of vocational behavior.     

Integrity of Literature on Expressed Emotion and Relapse in Patients with Schizophrenia Verified by a p‐Curve Analysis

There is growing concern that much published research may have questionable validity due to phenomena such as publication bias and p‐hacking. Within the psychiatric literature, the construct of expressed emotion (EE) is widely assumed to be a reliable predictor of relapse across a range of mental illnesses. EE is an index of the family climate, measuring how critical, hostile, and overinvolved a family member is toward a mentally ill patient. No study to date has examined the evidential value of this body of research as a whole. That is to say, although many studies have shown a link between EE and symptom relapse, the integrity of the literature from which this claim is derived has not been tested. In an effort to confirm the integrity of the literature of EE predicting psychiatric relapse in patients with schizophrenia, we conducted a p‐curve analysis on all known studies examining EE (using the Camberwell Family Interview) to predict psychiatric relapse over a 9‐ to 12‐month follow‐up period. Results suggest that the body of literature on EE is unbiased and has integrity, as there was a significant right skew of p‐values, a nonsignificant left skew of p‐values, and a nonsignificant test of flatness. We conclude that EE is a robust and valuable predictor of symptom relapse in schizophrenia.     

Caregiver Expressed Emotion and Psychiatric Symptoms in African‐Americans with Schizophrenia: An Attempt to Understand the Paradoxical Relationship

Expressed emotion (EE) is a family environmental construct that assesses how much criticism, hostility, and/or emotional over‐involvement a family member expresses about a patient (Hooley, Annual Review of Clinical Psychology, 2007, 3, 329). Having high levels of EE within the family environment has generally been associated with poorer patient outcomes for schizophrenia and a range of other disorders. Paradoxically, for African‐American patients, high‐EE may be associated with a better symptom course (Rosenfarb, Bellack, & Aziz, Journal of Abnormal Psychology, 2006, 115, 112). However, this finding is in need of additional support and, if confirmed, clarification. In line with previous research, using a sample of 30 patients with schizophrenia and their primary caregivers, we hypothesized that having a caregiver classified as low‐EE would be associated with greater patient symptom severity. We also aimed to better understand why this pattern may exist by examining the content of interviews taken from the Five‐Minute Speech Sample. Results supported study hypotheses. In line with Rosenfarb et al. (2006), having a low‐EE caregiver was associated with greater symptom severity in African‐American patients. A content analysis uncovered some interesting patterns that may help elucidate this finding. Results of this study suggest that attempts to lower high‐EE in African Americans may, in fact, be counterproductive.     

The levels of perceptual processing and the neural correlates of increasing subjective visibility

According to the levels-of-processing hypothesis, transitions from unconscious to conscious perception may depend on stimulus processing level, with more gradual changes for low-level stimuli and more dichotomous changes for high-level stimuli. In an event-related fMRI study we explored this hypothesis using a visual backward masking procedure. Task requirements manipulated level of processing. Participants reported the magnitude of the target digit in the high-level task, its color in the low-level task, and rated subjective visibility of stimuli using the Perceptual Awareness Scale. Intermediate stimulus visibility was reported more frequently in the low-level task, confirming prior behavioral results. Visible targets recruited insulo-fronto-parietal regions in both tasks. Task effects were observed in visual areas, with higher activity in the low-level task across all visibility levels. Thus, the influence of level of processing on conscious perception may be mediated by attentional modulation of activity in regions representing features of consciously experienced stimuli.     

Inter-individual neural differences in movement imagery abilities

ObjectivesBuilding on mounting evidence distinguishing the neurological basis of different movement imagery abilities (visual versus kinesthetic), this study compared brain activity (i.e., blood flow changes) through functional magnetic resonance imaging elicited by movement imagery in participants self-reporting good and poor imagery abilities with the Movement Imagery Questionnaire-3. Participants also completed the Vividness of Movement Imagery Questionnaire-2. Method: Thirty-seven females (good imagery ability = 18; poor imagery ability = 19) were randomly presented with four experimental conditions (i.e., Kinesthetic, Internal Perspective, External Perspective and Rest) counterbalanced for condition, during three separate 11-min functional brain scans. Results: Kinesthetic and visual (internal/external) subscale mean differences of the Vividness of Movement Imagery Questionnaire-2 favored good imagers and high Movement Imagery Questionnaire-3 inter-scale correlations evidenced convergent validity. As in prior published work, kinesthetic, internal, and external visual imagery elicited distinct patterns of brain activation relative to rest. Overall, the patterns of brain activity in the good and poor imager groups were remarkably similar, indicating that they both generally relied on a similar brain network during movement imagery. Conclusions: Contrary to processing efficiency hypotheses (i.e., neural efficiency hypothesis) we report that during kinesthetic imagery and external visual imagery only, good imagers actually activated a greater number of spatially distinct cortical sites than did poor imagers. Furthermore, research is needed to fully characterize the neural signature of movement imagery in good and poor imagers. Such research is critical to the appropriate creation and proper application of neuroscience-inspired movement imagery-based learning interventions in healthy and clinical populations.     

How are recent changes to primary care mental health provision within the NHS affecting psychodynamic counsellors’ construction and management of their professional identities? A Foucauldian perspective

The research used Foucauldian techniques to explore how counsellors currently working for the NHS construct and manage their professional identities in the face of changes imposed on them by the institution. Semi-structured interviews were carried out with four counsellors and one doctoral student, all with substantial experience working for the NHS. A Foucauldian Discourse Analysis revealed four main subjectivities that were made available; feeling like part of a process at times; the NHS imposes limitations on their practice; feeling able to retain their professional standards despite the limitations and lack of influence; feeling proud of, and satisfied with the work they do. Places in which the participants explored ways of constructing a professional identity were also explored.

Understanding the influence of literacy on consumer memory: The role of pictorial elements

This research examines the relationship between literacy and consumer memory. The effects of a variety of stimuli at exposure (i.e., brand names, brand signatures, and products in usage) on memory (i.e., recognition, stem-completion tasks) were examined for a range of literacy. In a series of experiments, we find that the use of pictorial representations of brands (i.e., brand signatures) results in superior brand memory for individuals with lower literacy levels when compared to those at higher literacy levels. This effect is shown to occur not due to pictorial elements per se, but due to pictorial elements with a 1-to-1 correspondence with reality, i.e., which match the form in which they were originally encoded in memory. Moreover, this effect does not persist with stimulus-rich pictures of brands in usage, pointing to boundary conditions with the use of pictorial information.
