The classification and integration of edges as critical to the perception of reflectance and illumination

A pattern of luminances equivalent to that of a traditional simultaneous lightness display (two equal gray squares, one on a white background and the other on an adjacent black background) was presented to observers under two conditions, and matches were obtained for both perceived reflectance and perceived illumination level of the squares and their backgrounds. In one condition, the edge dividing the two backgrounds was made to appear as the boundary between a white and a black surface, as in the traditional pattern. The squares then were perceived as almost the same shade of middle gray. In the other condition, a context was supplied that made the edge between the backgrounds appear as the boundary between two illumination levels, causing one square to appear black and the other white. These results were interpreted as a problem for local ratio theories, local edge theories, and lateral inhibition explanations of lightness constancy, but as support for the concepts of edge classification, edge integration, and the retinal image as a dual image.     

Correlates of depressed mood in normal children

Two instruments which have been proposed as measures of clinical depression in children and an ad hoc teacher rating were given to a group of 109 normal children. The Children's Depression Inventory (CDI), the Peer Nomination Inventory for Depression (PNID), and a teacher rating of depression were given along with the Conner s Teacher Rating Scale (TRS), teacher ratings of somatic complaints, peer popularity, and absenteeism, and peer ratings of popularity to examine the behavioral correlates of depressed mood in normal children. While few sex differences were found on mean depression scores, different patterns of correlations were found for the two sexes. For males, there were no significant correlations among the three depression measures, but all three depression measures were correlated with unpopularity and conduct problem ratings on the TRS. For females, the three depression measures were adequately intercorrelated. The teacher rating of depression was correlated with general deviance as measured by the TRS, but the CDI and PNID were correlated with TRS ratings of conduct problems, with peer ratings of unpopularity, and with teacher ratings of somatic complaints. Implications for the issue of the possible existence of a clinical syndrome of depression in children were discussed.     

The efficacy of rational-emotive group therapy in psychiatric inpatients

The impact of rational-emotive theory and therapy upon the practice of clinical psychology has been profound, and many purportedly objective experimental tests of its efficacy as a mode of treatment have been reported. Yet the great majority of these reports have failed to utilize actual clinical populations. This study evaluated rational-emotive group therapy with psychiatric inpatients. Results supported the claim that irrational beliefs are related to emotional disturbance. It was also shown that patients undergoing rational-emotive group therapy changed their self-reported irrational beliefs more than did a control group. Finally, there was a trend for the experimental subjects to be more likely to have been discharged from the hospital during the 90-day follow-up period than were control subjects. However, this study failed to demonstrate that change in irrational beliefs was related to improvement in psychiatric symptoms or rates of discharge from the hospital. Some of the difficulties in conducting treatment evaluation research in a psychiatric hospital setting are discussed with respect to these results.

‘Second generation’ Sikh autobiographies and authobiographical novels in European languages: Turning towards and away from traditions

ABSTRACT

The article analyzes autobiographies and autobiographical novels by Sikh authors who were born and grew up in Europe and North America as sources for understanding developments of Sikh religion. It uses the concepts panjabiat (Punjabi-ness), Sikh religion and modernity/Western society to understand the tensions and conflicts described in these books. The authors had to work out the differences between panjabiat, Sikh religion and modernity/Western society. They had to figure out what place the Sikh religion should have in their new identity and for this they were looking for similarities between the Sikh religion and Western society. In the autobiographies Sikh religion emerges as an ideology employed to criticize Punjabi culture and society and Sikh religion is reinterpreted and often comes to refer to some general principles that are compatible and supportive of Western modernity.

Processes in acceptance and commitment therapy and the rehabilitation of chronic fatigue

Acceptance and commitment therapy (ACT) has never been tested for patients with chronic fatigue. We aimed to test if a 3.5‐week ACT rehabilitation program for patients with chronic fatigue improved quality of life (QoL), fatigue, and psychological flexibility. Further, to test if improvements in QoL and fatigue were associated with improvement in psychological flexibility, and if psychological flexibility explained variance above and beyond maladaptive cognitions typically targeted in CBT for fatigue. Patients (n = 140) who had been on sick leave > 8 weeks due to chronic fatigue received a 3.5‐week non‐controlled inpatient rehabilitation program based on ACT. A physician and a psychologist examined the patients, assessing medication use and SCID‐I diagnoses. Patients completed questionnaires about somatic complaints, psychological complaints, and maladaptive cognitions before and after treatment. At post‐treatment, patients reported improved QoL (p < 0.001; g = 1.07) and less fatigue (p < 0.001; g = 1.08), but not increased psychological flexibility (p = 0.6). Changes in psychological flexibility was associated with improved QoL, but not fatigue, in hierarchical regression analyses. When adjusting for other cognitions, changes in fear‐avoidance cognitions and all‐or‐nothing thoughts, but not psychological flexibility, were associated with improved QoL and fatigue. The ACT‐based treatment improved QoL and reduced fatigue for patients with chronic fatigue with large effect sizes. Improvement was associated with a reduction in fear‐avoidance cognitions and all‐or‐nothing thoughts, but not psychological flexibility.     

Group Narrative Therapy for Women With Attention‐Deficit/Hyperactivity Disorder

Women with attention‐deficit/hyperactivity disorder (ADHD) often struggle with the developmental challenges of adulthood and ADHD‐related problems. The authors provide specific clinical interventions from a narrative‐based group approach to help women with ADHD understand their symptoms, create strength‐based narratives, and apply these narratives to the developmental tasks of early adulthood.     

Neurocognitive impairment does not predict treatment outcome in obsessive-compulsive disorder

There is conflicting evidence pertaining to whether or not neurocognitive task performance at baseline predicts treatment response in obsessive-compulsive disorder (OCD). In the present study, we administered a set of executive neurocognitive tests with a putative sensitivity for treatment outcome to a sample of 138 OCD patients. Additionally, subjective neurocognitive dysfunction was determined via a questionnaire. All patients participated in a cognitive-behavioural treatment program (CBT). Results showed that responders (n = 73) did not differ from non-responders (n = 65) on any of the parameters except for decreased performance on the delayed alternation test (p < .1, effect size: .61). A subsidiary analysis revealed that slowing on the Trail-Making Test A and an enhanced rate of perserveration errors on the Wisconsin Card Sorting Test predicted poor outcome for the treatment of compulsions. It is concluded that neurocognitive impairment does not represent a reliable early warning sign for non-response to CBT.
