Achievement of specificational information usage with true and false feedback in learning a visual relative-mass discrimination task

Participants' usage of informational variables in learning visual relative-mass discrimination in collisions was tracked by means of PROBIT correlations. Four groups received feedback that was true or accorded with either of three nonspecificational cue variables. A majority in each group adopted the feedback, but several participants defied the false feedback. Unlike in previous research, the fit to data of the relative-mass invariant could not be bettered by post hoc linear combinations of the cues. Discriminability was lower in the use of the invariant. Analytic complexity was rejected as an explanation for discriminability differences. A "smart mechanism" for pickup of the relative-mass invariant was developed as an extension of G. Johansson's (1950/1994) vector model.     

The spirited, the observant, and the disheartened: social concepts of optimism, realism, and pessimism

The social concepts of optimism, pessimism, and realism were investigated by assessing the prototypical acts (thoughts, feelings, goals, and actions) that laypersons assign to optimists, pessimists, and realists responding to a controllable and an uncontrollable situation. Optimists and realists, but not pessimists, were seen as adjusting their behavior to the situation. However, whereas optimists were characterized by flexibility in thoughts and feelings but invariance in goals and actions (i.e., they pursued their goals in both controllable and uncontrollable situations), the act profiles assigned to realists varied on all of these dimensions. The profile assigned to pessimists was characterized by cognitive, affective, motivational, and behavioral invariance, encompassing negative construals of the situation, giving up, and a focus on distress.     

Fatigue, cognitive functioning and psychological distress in Marfan syndrome, a pilot study

Marfan patients report fatigue as a major subjective complaint. We found no studies exploring the subject. The aim of this study was in a strictly defined Marfan population to assess self-reported fatigue, cognitive functions and psychological distress, correlations among them and correlations to visual acuity, joint hypermobility and use of beta-blockers. Sixteen subjects aged 18 - 30 years, fulfilling the Gent criteria, were assessed with the Fatigue Severity Scale, Fatigue Questionnaire, a comprehensive battery of neuropsychological tests and the General Health Questionnaire (GHQ). Self-reported fatigue was comparable with fatigue reported in other severe chronic diseases and disabilities, and was primarily in the mental/psychological domain. Psychological distress was higher than expected compared with the population at large. All neuropsychological test results were within the normal range, except for tests of visuo-motor coordination and speed of information processing. There was a significant inverse correlation between Fatigue Questionnaire ratings and some neuropsychological tests. Fatigue seems to be a serious problem for persons with Marfan syndrome and seems related to some areas of cognitive functioning. We found no overall impairment in cognitive functioning, but slightly reduced speed of information processing. Reduced visuo-motor coordination could be explained by impaired visual acuity.     

Therapeutic alliance in guided internet-delivered cognitive behavioural treatment of depression, generalized anxiety disorder and social anxiety disorder

Guided internet-delivered cognitive behaviour therapy (ICBT) has been found to be effective in several controlled trials, but the mechanisms of change are largely unknown. Therapeutic alliance is a factor that has been studied in many psychotherapy trials, but the role of therapeutic alliance in ICBT is less well known. The present study investigated early alliance ratings in three separate samples. Participants from one sample of depressed individuals (N = 49), one sample of individuals with generalized anxiety disorder (N = 35), and one sample with social anxiety disorder (N = 90) completed the Working Alliance Inventory (WAI) modified for ICBT early in the treatment (weeks 3-4) when they took part in guided ICBT for their conditions. Results showed that alliance ratings were high in all three samples and that the WAI including the subscales of Task, Goal and Bond had high internal consistencies. Overall, correlations between the WAI and residualized change scores on the primary outcome measures were small and not statistically significant. We conclude that even if alliance ratings are in line with face-to-face studies, therapeutic alliance as measured by the WAI is probably less important in ICBT than in regular face-to-face psychotherapy.     

Outcome predictors in guided and unguided self-help for social anxiety disorder

Internet-based self-help with therapist guidance has shown promise as an effective treatment and may increase access to evidence-based psychological treatment for social anxiety disorder (SAD). Although unguided self-help has been suggested primarily as a population-based preventive intervention, some studies indicate that patients with SAD may profit from unguided self-help. Gaining knowledge about predictors of outcome in guided and unguided self-help for SAD is important to ensure that these interventions can be offered to those who are most likely to respond. Utilizing a sample of 245 patients who received either guided or unguided self-help for SAD, the present study examined pre-treatment symptoms and program factors as predictors of treatment adherence and outcome. The results were in line with previous findings from the face-to-face treatment literature: namely, the intensity of baseline SAD symptoms, but not depressive symptoms, predicted treatment outcomes in both unguided and guided self-help groups. Outcomes were unrelated to whether a participant has generalized versus specific SAD. Furthermore, for the unguided self-help group, higher credibility ratings of the treatment program were associated with increased treatment adherence. The findings suggest that guided and unguided self-help may increase access to SAD treatment in a population that is more heterogeneous than previously assumed.     

Self-control as predictor of school grades,life balance,and flow in adolescents

Background. Recently, several studies have shown that strength of self-control is a crucial factor in determining positive outcomes in individuals’ lives. Most attention has been directed to the relationships that self-control has with learning and academic achievement. Aims. This article analyses the effects of self-control not only on school grades but also on the experience of life balance and flow. It is theorized that students with a higher level of self-control are better able to distribute their time in a satisfying way over academic and leisure matters, and are better able to shield their studying against distractions. Samples. A total of 697 eighth graders with a mean age of 13.4 years participated in the longitudinal study. Method. Students completed a questionnaire containing measures of self-control, school grades, subjective life balance, and flow while studying at the beginning and at the end of the school year. Structural equation modelling was used to analyse the relationships between the constructs. Results and conclusions. Results of cross-lagged analyses show that self-control predicted school grades, life balance, and flow. The findings suggest that self-control may assist adolescents to be better prepared, not only for school, but also for coordinating their investments in different areas of their lives.     

Visuospatial attention in schizophrenia: deficits in broad monitoring

Although selective attention is thought to be impaired in people with schizophrenia (PSZ), prior research has found no deficit in the ability to select one location and withdraw attention from another. PSZ and healthy control subjects (HCS) performed a stimulus detection task in which one, two, or all four peripheral target locations were cued. When one or two locations were cued, both PSZ and HCS responded faster when the target appeared at a cued than uncued location. However, increases in the number of validly cued locations had much more deleterious effects on performance for PSZ than HCS, especially for targets of low contrast whose detection was more dependent on attention. PSZ also responded more slowly in trials with four cued locations relative to trials with one or two invalidly cued locations. Thus, visuospatial attention deficits in schizophrenia arise when broad monitoring is required rather than when attention must be focused narrowly.     

The Rumsfeld effect: the unknown unknown

A set of studies tested whether people can use awareness of ignorance to provide enhanced test consistency over time if they are allowed to place uncertain items into a "don't know" category. For factual knowledge this did occur, but for a range of other forms of knowledge relating to conceptual knowledge and personal identity, no such effect was seen. Known unknowns would appear to be largely restricted to factual kinds of knowledge.     

Contagious bodies. An investigation of affective and discursive strategies in contemporary online activism

The paper presents an analysis of Climate Justice Fast, a campaign consisting of an international hunger strike against political in action on climate change. Within the theoretical framework of political online activism and theories of affect, we investigate the encoding and decoding of the starving activist bodies in relation to CJF. Our material consists of texts from the CJF website, activist blogs, and two online debates on a large Danish media platform. The methodological approach is discourse analytical and esthetic-affective. In our analysis we outline the different semantic significations of the starving bodies as central signifiers and we investigate the different affective responses to the hunger strike. We furthermore argue that the starved body seems to be relationally powerful, because of both its contagious ability to attune other bodies and its semantic ‘wildness’.
