Executive working memory processes in dyslexia: Behavioral and fMRI evidence

Beneventi, H., Tønnessen, F. E., Ersland, L. & Hugdahl, K. (2010). Executive working memory processes in dyslexia: Behavioral and fMRI evidence. Scandinavian Journal of Psychology, 51, 192–202. Dyslexia is an impairment in learning to read and write, primarily associated with a phonological core deficit. However, the manifestation of symptoms in dyslexia also includes impaired working memory (WM). The aim of this study was to investigate cortical activation related to verbal WM in dyslexic and normal readers aged around 13 years, controlling for phonological awareness processing. We used a modified WM n‐back task where the participants remembered the first or last speech segment (phonemes) of the names of common objects shown as pictures. Dyslexic readers were impaired compared with the control group. Compared with the dyslexic readers, controls showed increased fMRI activation in the left superior parietal lobule and the right inferior prefrontal gyrus. Unlike controls, dyslexics did not show a significant increase in activation in WM areas with increased memory load. These findings provide support for a specific working memory deficit in dyslexic individuals.     

Symptomatic distress and effectiveness of psychological treatments delivered at a nationwide student counseling service

The aim of this study is to investigate the effectiveness of student counseling in Denmark and to compare the symptomatic distress among student counseling clients with that of Danish outpatients. The pre-intervention level of self-reported symptomatic distress among 1256 students closely paralleled that of psychiatric outpatients. Participants in the intervention study were the 739 student clients with two or more counseling sessions. For the 530 (71.7%) participants with both pre- and post-measurements, the mean pre–post Cohen’s d effect size (ES) was .76 on the Global Severity Index of the Symptom Check List-90-Revised. An intention-to-treat analysis of all 739 clients resulted in an ES of .59. The number of recovered clients according to the Jacobson and Truax criteria was 295 (68.8%) of the 429 (80.9%) clients above the clinical cut-off at pre-intervention, while 66 (12.5%) of the 530 clients reliably deteriorated. The mean number of sessions was 5.0. Individual counseling, number of sessions, and ending counseling in agreement predicted better outcome. In line with results from other countries, this study may indicate that in Denmark student counseling is an effective intervention for a highly needy clientele, even though a high proportion of clients deteriorated (12.5%) or dropped out (31.7%).     

Factor structure of the Behavior Rating Inventory of Executive Functions (BRIEF-P) at age three years

The preschool period is an important developmental period for the emergence of cognitive self-regulatory skills or executive functions (EF). To date, evidence regarding the structure of EF in preschool children has supported both unitary and multicomponent models. The aim of the present study was to test the factor structure of early EF as measured by the Behavior Rating Inventory of Executive Function-Preschool version (BRIEF-P). BRIEF-P consists of five subscales and three broader indexes, hypothesized to tap into different subcomponents of EF. Parent ratings of EF from a nonreferred sample of children recruited from the Norwegian Mother and Child Cohort Study (N = 1134; age range 37–47 months) were subjected to confirmatory factor analyses (CFA). Three theoretically derived models were assessed; the second-order three-factor model originally proposed by the BRIEF-P authors, a “true” first-order one-factor model and a second-order one-factor model. CFA fit statistics supported the original three-factor solution. However, the difference in fit was marginal between this model and the second-order one-factor model. A follow-up exploratory factor analysis (EFA) supported the existence of several factors underlying EF in early preschool years, with a considerable overlap with the five BRIEF-P subscales. Our results suggest that some differentiation in EF has taken place at age 3 years, which is reflected in behavior ratings. The internal consistency of the BRIEF-P five clinical subscales is supported. Subscale interrelations may, however, differ at this age from those observed in the preschool group as a whole.     

Prevalence of auditory verbal hallucinations in a general population: A group comparison study

The present study was specifically designed to investigate the prevalence of auditory verbal hallucinations (AVH) in the general population, and sought to compare similarities and differences regarding socio‐demographics, mental health and severe life events between individuals who have never experienced AVH with those who had. The study also aimed to compare those who sought professional help for their experience of AVH with those who had not sought help. Through a postal questionnaire, 2,533 participants ages 18 and over from a national survey completed the Launay‐Slade Hallucinations Scale and other measures examining AVH characteristics and other areas related to AVH. In total, 7.3% of the sample reported a life‐time prevalence of AVH. Those with AVH were more likely to be single and unemployed, reported higher levels of depression and anxiety, and experienced a higher number of severe life events compared with those without AVH. Only 16% of those who experienced AVH in the general population sought professional help for these experiences. Compared to those who did not seek professional help, participants that had were more likely to experience AVH with a negative content, experience them on a daily basis, undergo negative reactions when experiencing AVH, and resist AVH. In conclusion, the prevalence of AVH was found to be relatively high. The results also revealed higher levels of reduced mental health for individuals who sought professional help, followed by those who did not, compared with those who had never experienced AVH.     

Sinking Cohen's Flagship — or Why People with Expensive Tastes Should not be Compensated

G. A. Cohen argues that egalitarians should compensate for expensive tastes or for the fact that they are expensive. Ronald Dworkin, by contrast, regards most expensive tastes as unworthy of compensation — only if a person disidentifies with his own such tastes (i.e. wishes he did not have them) is compensation appropriate. Dworkinians appeal, inter alia, to the so‐called ‘first‐person’ or ‘continuity’ test. According to the continuity test, an appropriate standard of interpersonal comparison reflects people's own assessment of their relative standing: Person A can only legitimately demand compensation from person B if he regards himself as worse off, all things considered, than B. The typical bearer of expensive tastes does not regard herself as being worse off than others with less expensive tastes. Hence, in the typical case, pace Cohen, compensation for expensive tastes is inappropriate. The article scrutinizes this rationale for not compensating for expensive tastes. Especially, we try to bolster the continuity test by relating it to Dworkin's distinction between integrated and detached values, pointing out that an argument for the continuity test can be built on the assumption that equality has integrated value. In brief, the point is that a metric of equality should be assessed, partly, in virtue of its consequences for related ideals. One of these is the kind of justificatory community promoted by the continuity test. We defend this view against an objection to the effect that equality is a detached value. We conclude that the continuity test constitutes a strong foothold for the resourcist egalitarian reluctance to compensate people for their expensive tastes.
