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.     

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.     

Job Stress and Organizational Learning Climate

Job stress may depend on the organizational learning climate, the organizational factors that affect learning how to cope with the rapid external and internal changes in working life. The relationship between individual job stress and the individual perception of learning climate was studied among 383 employees in the Norwegian Postal Service and in various community health care institutions. Mismatch between individual perceptions of learning climate and the averaged evaluation of learning climate in the rest of the working group, was found to be an important source of stress. Individuals who perceived the learning climate as good and who were working in a group that agreed with this position, had a low job-stress level. This may be ascribed to their feeling of control over the work situation and reduced demands due to the social support from the group, producing a low job stress level.     

Attendance pressure during organizational change

The present study examines the relationships between aspects of the concept attendance pressure and sickness absenteeism. The study was carried out in a large public company in Norway during a major reorganization. It was hypothesized that employees with sickness absenteeism during this period would experience a high degree of attendance pressure in the form of reactions from managers, fellow workers, and job insecurity. Two surveys were carried out with the same sample (N=401). Attendance pressure in the form of censure pressure explained significant parts of the variance in sickness absenteeism. Employees with sickness absenteeism during the reorganization were a vulnerable group with low job satisfaction, significant health problems and low personal work ethics. Implications for preventive work on organizational level are discussed.Financed by the Research Council of Norway.     

Age and brief separation: Note on children's distress reactions

26 children, one to three years old, were briefly separated from their parents in a strange situation in order to investigate the relation of age to children's crying and manipulation behavior. A significant negative correaltion was found between age and crying ( r =÷0.51), while no relation was observed between age and manipulation. The results support Bowlby's (1973) view that the peak of separation distress occurs during the child's second year of life.     

Social and emotional loneliness and self‐reported difficulty initiating and maintaining sleep (DIMS) in a sample of Norwegian university students

Social and emotional loneliness negatively impact several areas of health, including sleep. However, few comprehensive population‐based studies have evaluated this relationship. Over 12,000 students aged 21–35 years who participated in the student survey for higher education in Norway (the SHoT study) were assessed. Loneliness was assessed using the Social and Emotional Loneliness Scale. Difficulty initiating and maintaining sleep (DIMS) was assessed by a single‐item subjective response on the depression scale of the Hopkins Symptoms Checklist (HSCL‐25). Social loneliness was associated with more serious DIMS (unadjusted proportional odds‐ratio [OR] = 2.69, 95% CI = 2.46–2.95). This association was attenuated following adjustment for anxiety (adjusted OR = 1.92, 95% CI = 1.75–2.10) and depression (adjusted OR = 1.48, 95% CI = 1.34–1.63), however was not substantially altered when all demographics and psychological distress were accounted for (fully adjusted OR = 1.46, 95% CI = 1.30–1.63). Emotional loneliness was also associated with more serious DIMS (unadjusted proportional OR = 2.33, 95% CI = 2.12–2.57). Adjustment for anxiety (adjusted OR = 1.96, 95% CI = 1.78–2.15) and depression (adjusted OR = 1.64, 95% CI = 1.48–1.80) attenuated, but did not extinguish this relationship in the fully adjusted model (adjusted OR = 1.22, 95% CI = 1.09–1.31). Mediation analyses revealed that the social loneliness‐DIMS association was fully attributed to psychological distress, while the emotional loneliness‐DIMS association was only partially mediated, and a direct association was still observed. Associations between social and emotional loneliness and subjective DIMS were embedded in a larger pattern of psychological distress. Mitigating underlying feelings of loneliness may reduce potentially deleterious effects on sleep health and psychological wellbeing in young adults.     

THE CONCEPT OF PHILOSOPHICAL EXPERIENCE

Abstract: We often speak about religious experience, and sometimes we speak about metaphysical experience. Yet we seldom hear about philosophical experience. Is philosophy purely a matter of theories and theses, or does it have an experiential aspect? In this article, I argue for the following three claims. First, there is something we might call philosophical experience, and there is nothing mystical about it. Second, philosophical experiences are expressed in something quite similar to what Kant called “aesthetic judgements.” Third, philosophical experiences are expressed by using words in what Wittgenstein called “secondary sense.” Finally, I try to show the educational significance of pursing philosophical experiences. Through articulating them one might find one's ground, and through articulating them in a less private and more universal form one might raise oneself to universality. Thus, in expressing philosophical experiences one aspires to speak in a universal voice.     

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%).     

Visual processing speed in old age

Mental speed is a common concept in theories of cognitive aging, but it is difficult to get measures of the speed of a particular psychological process that are not confounded by the speed of other processes. We used Bundesen’s (1990) Theory of Visual Attention (TVA) to obtain specific estimates of processing speed in the visual system controlled for the influence of response latency and individual variations of the perception threshold. A total of 33 non‐demented old people (69–87 years) were tested for the ability to recognize briefly presented letters. Performance was analyzed by the TVA model. Visual processing speed decreased approximately linearly with age and was on average halved from 70 to 85 years. Less dramatic aging effects were found for the perception threshold and the visual apprehension span. In the visual domain, cognitive aging seems to be most clearly related to reductions in processing speed.
