Lexical decision and the number of morphemes and affixes

There has been a considerable amount of research looking at the effects of both syllable number and syllable frequency on lexical decision and word naming times. Recently, there has also been an increased interest in morphological variables, but there have been no large scale studies that have examined the role of the number of morphemes in lexical decision for nonwords. This is partly because of the difficulty of identifying morphemes in nonwords. We present a program that identifies the presence of affixes and, therefore, can be used to count the number of morpheme‐like elements in a nonword. We then used the program to measure the importance of affixes/morphemes in predicting lexical decision in nonwords. The results suggested that morphemes have an important role in lexical decision for both words and nonwords.     

Toward an Integration of Interpersonal Risk Models of Depression and Cognitive‐Behaviour Therapy

Empirical research has increasingly focused on interpersonal variables associated with the development and maintenance of depression. This article outlines some key interpersonal risk factors for depression, including anxious attachment, sociotropy, excessive reassurance seeking, interpersonal stress generation, reduced social support, social skills deficits, and social avoidance. Recommendations are made for how cognitive‐behavioural therapy may be adapted to address such factors. Specifically, suggestions are offered for how cognitive and behavioural interventions, such as cognitive restructuring, behavioural activation, behavioural experiments, and skills training, may be used with depressed clients to promote positive relationships and reduce maladaptive interpersonal behaviours.     

Emotional processing of individuals high in psychopathic traits

One of the most important clinical features of psychopaths is their differential emotional response style. The present study examined the modulating effect of negative mood induction on the processing of emotional information and its relation to psychopathy. The sample of 105 participants were randomly assigned to two types of mood induction conditions (negative vs neutral) and viewed three types of visual stimuli (positive, neutral, negative). Psychopathic Personality Inventory‐R (PPI‐R; Lilienfeld & Andrews) was employed to measure their psychopathic traits. It was hypothesized that individuals high on PPI‐II (i.e., self‐centered impulsivity) would show greater response latencies to emotionally negative pictures when they were induced into a negative mood compared to individuals high on PPI‐I (i.e., fearless dominance). In general, individuals high on PPI‐II showed greater response latencies to emotionally negative pictures, but their responsivity did not vary as a function of mood manipulation or task demands. When controlling the influence of other PPI factors, PPI‐I predicted reaction time (RT) facilitation to positive pictures in general (i.e., faster RT), and when interacting with a negative mood induction, it predicted longer viewing time of and more difficulty disattending from positive pictures (i.e., slower RT). These results were discussed within emotional processing theory associated with psychopathy.     

Prediction of the configuration of a ‘Bardeen–Herring’ dislocation climb source under dynamic conditions

Abstract

The sequence of events during the operation of a ‘Bardeen-Herring’ climb source is predicted by using a numerical method in which the dislocation is modelled as a set of finite straight elements. The configuration is determined as a function of the applied stress and an approximate analytical treatment is presented which describes the time dependence of the source operation.     

The use of diabetes-specific perceived control and health belief measures to predict treatment choice and efficacy in a feasibility study of continuous subcutaneous insulin infusion pumps

Abstract

In the course of a feasibility study of continuous subcutaneous insulin infusion pumps, 382 insulin-requiring diabetic patients were offered a choice of CSII, intensified conventional treatment or conventional treatment. Two hundred and eighty-six (75%) patients completed newly developed diabetes-specific measures of health beliefs and attributions before any change of treatment regimen. The scales were useful predictors of patients' choice of treatment. Furthermore, they were useful in predicting efficacy of treatment in terms of glycosylated haemoglobin measures of diabetes control after one year of treatment in the study. The implications of the findings for introducing patients to new forms of treatment are discussed.
