Context Memory in Korsakoff’s Syndrome

Memory for contextual information and target-context integration are crucial for successful episodic memory formation and are impaired in patients with Korsakoff's syndrome. In this paper we review the evidence for the notion that a context memory deficit makes an important contribution to the amnesia in these patients. First, we focus on anterograde memory for contextual (spatial and temporal) information. Next, the use of contextual cues in memory retrieval is examined and their role in retrograde amnesia and confabulation. Evidence on the role of contextual cues and associations in working memory is discussed in relation to the underlying neurocognitive mechanisms and their dissociation from long-term encoding. Finally, we focus on implicit learning of contextual information in Korsakoff patients. It can be concluded that Korsakoff patients are impaired in the explicit processing of contextual information and in target-context binding, both in long-term (retrograde and anterograde) memory and in working memory. These results extend the context memory deficit hypothesis. In contrast, implicit contextual learning is relatively preserved in these patients. These findings are discussed in relation to evidence of dysfunction of the extended diencephalic-hippocampal memory circuit in Korsakoff's syndrome.     

A systematic review of motivational interviewing within musculoskeletal health

Motivational interviewing (MI) has been investigated within a range of healthcare environments though to date no studies have systematically assessed its application and effectiveness within musculoskeletal health. The aim of this study is to identify interventions that have utilised MI to create change within musculoskeletal healthcare, evaluate quality and effectiveness, as well as identify the level of training received by those utilising the approach. The search strategy identified both published and unpublished or grey literature through electronic resources, reference list and content searches. Five studies were identified for quality assessment. Due to variations in delivery modality, musculoskeletal condition and type of MI application it was not possible to provide direct comparative interpretations for these factors. A data synthesis was used to provide a summary of study characteristics, a narrative overview and conduct a quality assessment as well as considering authors comments on study limitations. The results of the quality assessment highlighted a number of methodological issues which supported and expanded upon those expressed by the studies authors. None of the studies contained children or young people and in terms of training there were variations in training provider, duration and competency, as well as variation in the fidelity of MI. The findings have highlighted the need for well designed randomised controlled trials that are suitability powered to measure the effectiveness of MI within musculoskeletal health. Future studies may consider the application of MI within musculoskeletal conditions in terms of self-management and its application to creating lifestyle changes (e.g., diet, exercise) for adults, as well as children and young people. Research currently being conducted may expand upon the evidence, feasibility and validity of MI within areas such as fibromyalgia, osteoporosis, arthritis, understanding of knee replacement and rehabilitation.     

Attention-Deficit Hyperactivity Disorder Symptoms and Entrepreneurial Orientation: A Replication Note

There is a small body of literature linking attention-deficit hyperactivity disorder (ADHD) and its symptoms to entrepreneurial manifestations. Some studies take a subclinical perspective by studying the presence of symptoms, while other studies take a clinical perspective by studying the formal diagnosis of ADHD. The entrepreneurial manifestations examined range from entrepreneurial intention to the choice to become self-employed and from entrepreneurial orientation (EO) to entrepreneurial success. Despite its prominence in the entrepreneurship literature, to date only one study tested for a link with EO. The present study aims to replicate the relationship between ADHD symptoms and EO using a large data set of French small business owners. We do so by discriminating between the two dimensions of ADHD, namely attention-deficit and hyperactivity, as well as the three dimensions of EO, namely innovativeness, proactiveness, and risk-taking. We do not find a link between ADHD and EO, although we do find a positive link between ADHD and the risk-taking subdimension of EO. Hyperactivity symptoms are positively related to EO, which is mainly driven by the subdimensions proactiveness and risk-taking. We do not find a link between attention-deficit symptoms and EO, though there is a negative link between attention-deficit and proactiveness.
