Performance of Dyslexic Children on Cerebellar and Cognitive Tests

In a previous study (A. J. Fawcett, R. I. Nicolson, & P. Dean, 1996), the authors had found strong behavioral evidence for cerebellar deficit in a panel of children with dyslexia. In the present study, the generality of those results was assessed. A battery of clinical tests for cerebellar dysfunction was administered, together with selected cognitive tests, to a further 59 dyslexic and 67 control children. The dyslexic children showed highly significant impairments on the cerebellar tests, with deficits on postural stability and muscle tone comparable in magnitude with their reading and spelling deficits. Furthermore, over 95% of the dyslexic children showed clear evidence of deficit on muscle tone or stability. The findings provide further evidence of the generality of cerebellar impairment in dyslexia. The implications of the cerebellar tests for screening in dyslexia are discussed.

There is long-standing evidence for verbal working memory impairments in both children and adults with dyslexia. By contrast, spatial memory appears largely to be unimpaired. In an attempt to distinguish between phonological and central executive accounts of the impairments in working memory, a set of phonological and spatial working memory tasks was designed to investigate the key issues in working memory, task type, task demands (static, dynamic, and updating), and task complexity. Significant differences emerged between the dyslexic and nondyslexic participants on the verbal working memory tasks employed in Experiment 1, thereby providing further evidence for continuing dyslexic impairments of working memory into adulthood. The nature of the deficits suggested a problem with the phonological loop, with there being little evidence to implicate an impairment of the central executive. Due to the difficulties associated with separating verbal working memory and phonological processing, however, performance was investigated in Experiment 2 using visuospatial measures of working memory. The results of the visuospatial tasks indicated no between-group differences in static spatial memory, which requires the short-term storage of simultaneously presented information. In almost all conditions there were no between-group differences in dynamic spatial memory that demands the recall of both location and order of stimuli presented sequentially. However, a significant impairment occurred on the dynamic task under high memory updating load, on which dyslexic adults showed nonphonological working memory deficits. In the absence of an explanation involving verbal recoding, this finding is interpreted in terms of a central executive or automaticity impairment in dyslexia.     

Eye movements during scene inspection: A test of the saliency map hypothesis

Both attentional difficulties and rapid processing deficits have recently been linked with dyslexia. We report two studies comparing the performance of dyslexic and control teenagers on attentional tasks. The two studies were based on two different conceptions of attention. Study 1 employed a design that allowed three key components of attention--focusing, switching, and sustaining--to be investigated separately. One hypothesis under investigation was that rapid processing problems--in particular impaired ability to switch attention rapidly--might be associated with dyslexia. However, although dyslexic participants were significantly less accurate than their controls in a condition where they had to switch attention between two target types, the nature of the deficit suggested that the problem was not in switching attention per se. Thus, in Study 2, we explored an alternative interpretation of the Study 1 results in terms of the classic capacity-limited models of "central" attention. We contrasted two hypotheses: (1) that dyslexic teenagers have reduced cognitive resources versus (2) that they suffer from a general impairment in the ability to automatise basic skills. To investigate the automaticity of the shape recognition component of the task a similar attention paradigm to that used in Study 1 was employed, but using degraded, as well as intact, stimuli. It was found that stimulus degradation led to relatively less impairment for dyslexic than for matched control groups. The results support the hypothesis that dyslexic people suffer from a general impairment in the ability to automatise skills--in this case the skill of automatic shape recognition.     

The role of stressful events in the relationship between positive and negative affects: evidence from field and experimental studies

Three studies are presented that examine the effects of stress on the relationship between positive and negative affective states. In the first study, recently bereaved and disabled older adults were compared to matched control groups without these recent stressors. Negative affect was inversely correlated with positive affect to a significantly greater extent for the highly stressed groups compared with controls. In a second study, older adults were exposed to a laboratory stressor, and their positive and negative affective reactions recorded. Immediately following a speech stressor task, the inverse correlation between positive and negative affect was significantly greater than in pre- and postassessments of affects. The third study was an attempt to replicate and extend the findings from Study 2 with a mid-aged sample of women. The speech stressor had the same effects as in Study 2. A second stressor, which induced pain through immersion of an arm into cold water, had no effects on the correlation between affective states. Alternative explanations for these effects and the implications for cognitive interventions are discussed.     

Is domestic violence a gender issue? Views from a British city1

Domestic violence involves the abuse, whether emotional, physical, sexual and/or economic, of one or more family (or ex‐family) members by another family member within the home or wider domestic context. It is typically associated with increasing entrapment, injury, medical complaints, psycho‐social problems and (sometimes) unsuccessful help‐seeking. Research evidence demonstrates that domestic abuse is prolific, prolonged, impacts physically, emotionally and economically upon women and children in particular, over the long‐term including well after they are ‘safe’ from the perpetrator. Furthermore, such abuse is widespread and happens all over the world. The findings reported here are from an observational population survey conducted in one British city to assess awareness of domestic violence. While there appears to be a broadly held and well‐informed definition of what actions constitute domestic violence and why it occurs, there are striking differences in perspective concerning public awareness of the frequency of domestic violence and knowledge of its importance as a safety issue indicating that it is still not seen generally as a serious social problem.

A brief report of women's expectations of men's behaviour in the transition to parenthood: Contradictions and conflicts for counselling psychology practice

Couples often seek counselling in the first year following the birth of a baby. The role and image of active fatherhood has affected women's expectations that their male partners will engage in baby/child care and other domestic activities. This pilot study of women undergoing the transition to motherhood within a heterosexual couple relationship indicates that women's expectations and men's ‘promises' and media images of fatherhood do not coincide with behaviour and that this causes and amplifies stress in the relationship. Counselling psychologists often focus upon the woman's involvement with the baby or lack of partner support as the main problematic dimension in the couple's well-being. It is suggested here, from the findings summarized, that more research needs to be done on the mismatch between changing attitudes to fathering and the impact of the consequent, apparently false expectations of men's behaviour in the early years of parenthood.     

Evaluation of a brief multiple-stimulus preference assessment in a naturalistic context

We evaluated a brief multiple-stimulus preference assessment within the context of an early intervention program for 3 children who had been diagnosed with autism. Subsequent curriculum-based reinforcer evaluations confirmed the predictions of the preference assessments. In addition, eight additional preference assessments that were conducted over a period of 1 month indicated generally stable preferences for 2 of the 3 participants.     

Counselling women with post natal depression: Implications from recent qualitative research

This paper explores the role of the counselling psychologist with women who experience post natal depression. Traditionally post natal depression has been identified as a clinical condition, and the woman referred for psychiatric assessment; or it is seen as the result of stressful childbirth and associated events, and the woman is offered treatment by her GP or referred to a post natal support group. A recent study suggests that some degree of depression following childbirth is ‘normal’, and that far from being a clinical condition, its origins appear to be located in the context of problematic relationships (in both domestic and obstetric settings) as well as in women's expectations and inadequate preparation for childbirth and early motherhood. These expectations seem to be embedded in female psychology and wider cultural values. Women appear to be prepared for the fact that they will bear and mother children, but not the experience of motherhood itself, and consequent changes in identity and relationships are rarely made explicit. This study suggests that childbirth and the early months of motherhood (even for second and third children) are likely to precipitate some degree of depression in most women, and that this depression appears to be reactive rather than determined by individual pathology. Further, the experience of becoming a mother (each time) equates with a model of loss and bereavement, suggesting a very specific role for the counselling psychologist.
