Nature against nurture: calcification in the right thalamus in a young man with anorexia nervosa and obsessive-compulsive personality disorder

This report describes the case of a young man with a large calcification in the right thalamus that was first diagnosed at 9 years of age. Case history reveals specific eating rituals and other obsessive-compulsive personality traits during the patient's childhood and adolescence, fulfilling diagnostic criteria of obsessive-compulsive personality disorder. After a critical life event the patient develops anorexia nervosa. We suggest that our case and further literature provide evidence for an involvement of specific thalamic structures, such as the dorsomedial nucleus, in the development of anorexia nervosa. Furthermore, the treatment of the patient by a combined psychotherapeutic and pharmacotherapeutic approach is described. We focus on the beneficial effect of the atypical antipsychotic olanzapine, which can induce weight gain by an increase of leptin levels.     

The Art of Becoming Human: Morality in Kant and Confucius

Kant and Confucius maintain that the art of becoming human is synonymous with the unending process of becoming moral. According to Kant, I must imagine a world in which the universality of my maxims were possible, while realizing that if such a world existed, then morality would disappear. Morality is an impossible possibility because it always meets resistance in our encounter with nature. According to Confucius, human beings become moral by integrating themselves into the already meaningful natural order that is tian 天. Like Kant, he upholds the dignity of human beings. For Kant this dignity rests on the autonomy of each human being’s reason, while for Confucius it is dependent upon our interconnection with each other, demanding ongoing self-extension. Despite these differences, the two thinkers would concur that our efforts at humanization are unceasing and that we may never fully live up to our human potential.     

The Effects of Adult Suggestion and Child Consistency on Young Children's Reports1

The purpose of the present study was to contrast the effects of children's response consistency and adult leading questions in a structured memory interview. Children (N = 70) who viewed a 2‐min video clip were asked 3 questions (leading, misleading, and neutral) related to the video. Children's responses (assent vs. deny) were predicted by the type of question asked by the adult (neutral, leading, and misleading), but not by the previous response given by the child or the child's age in months. Specifically, children assented the least often to misleading questions. Accuracy was predicted by both question type and in the last question–answer pair, children's previous response accuracy. These findings are discussed with relation to interview dynamics.     

Diagnostik in der Verhaltenstherapie

After an introduction, a short historical review of the development of behaviour therapy and the importance of categorical classification of mental disorders is given. We present different assessment approaches that are important in behaviour therapy. They comprise anamnesis, categorical classification, somatic differential diagnosis, psychometric methods, ratings scales, and diaries. As the core assessment strategy in cognitive behaviour therapy, functional behavioural analysis is introduced in detail, in which methods of horizontal analysis of behaviour (SORKC model proposed by Kanfer) and the vertical analysis of behaviour are explained. The importance of computer-based assessment and specific approaches of assessment within behaviour therapy for children and adolescents are presented. By way of conclusion, the prospects of possible new developments of assessment in behaviour therapy are outlined.     

Relationship commitment and its implications for unprotected sex among impoverished women living in shelters and low-income housing in Los Angeles County.

OBJECTIVE: To examine how relationship commitment among impoverished women is associated with their frequency of unprotected sex. DESIGN: Cross-sectional analyses were conducted on survey data from a probability sample of 445 women initially sampled from shelters and low-income housing in Los Angeles County. MAIN OUTCOME MEASURE: Frequency of unprotected sex in a typical month was derived as the product of 2 items: how often the woman had sex with her partner in a typical month and how often a male condom was used. RESULTS: For both sheltered and housed women, relationship commitment predicted more frequent engagement in unprotected sex with their partner, even after controlling for the type of relationship (primary vs. casual). However, this association could not be accounted for by perceived partner monogamy, ability to refuse unwanted sex, perceived HIV susceptibility, and condom use self-efficacy. Among housed women only, never asking the partner to use a condom partially accounted for more frequent engagement in unprotected sex among women with stronger relationship commitment. CONCLUSION: Results emphasize the importance of relationship commitment issues in HIV prevention interventions with impoverished women, and the need for a better understanding of relationship commitment and its influence on condom use in this population.     

Does trampolining and anaerobic physical fitness affect sleep?

The structure of nocturnal sleep of 16 volunteers, participating in the anaerobic sports of trampolining, dancing, and soccer, was monitored by means of polygraphic recordings. Since trampolining requires the acquisition of unfamiliar patterns of motor coordination, it can be considered as a special form of motor learning, whereas the acquisition of motor skills specific for dancing and soccer can be linked with motor patterns of normal biped locomotion. According to this view, an experimental group of 8 volunteers was formed; they participated in a training course of trampolining. In addition, a control group of 8 subjects was recruited, who engaged in one of the other two anaerobic sports. Subjects who had acquired new motor skills during a 13-wk. program in trampolining showed a statistically significant increase in REM-sleep. By contrast, the 8 subjects of the control group showed no considerable changes in REM-sleep. This suggests that efforts in acquiring new and complex motor patterns activate processes specifically involved in the generation of REM stage during nocturnal sleep.     

Dynamic aspects of stimulus-response correspondence: evidence for two mechanisms involved in the Simon effect

It has been recently proposed that the time course of the Simon effect may vary across tasks, which might reflect different types of stimulus-response (S-R) transmissions (E. Wascher, U. Schatz, T. Kuder, & R. Verleger, 2001). The authors tested this notion in 4 experiments by comparing Simon effects evoked by horizontal and vertical S-R arrangements. The temporal properties of the effect, as well as lateralized readiness potential-difference waves, indicated a fast and transient influence of the horizontal, but a slow and sustained influence of the vertical spatial stimulus feature on performance. Additional evidence for this temporal dissociation was obtained in experiments that induced a shortening or lengthening of the mean response time. Thus, the data strongly indicate that there are 2 temporally dissociable mechanisms involved in generating the Simon effect for horizontal and vertical S-R relations.     

The relationships between television viewing in midlife and the development of Alzheimer's disease in a case-control study

The relationship between leisure activities and development of cognitive impairment in aging has been the subject of recent research. We examined television viewing in association with risk of developing Alzheimer's disease (AD) in a case-control study. Given recent focus on the importance of intellectually stimulating activities as preventive measures against cognitive decline, it is important to examine the effects of less stimulating but common activities. Data are from 135 Alzheimer's disease cases and 331 healthy controls. Demographic characteristics and life history questionnaire responses on the number of hours spent on 26 leisure activities during middle-adulthood (ages 40-59) were analyzed. Logistic regression was used to examine the effects of middle-adulthood leisure activities on case vs. control status. Results indicate that for each additional daily hour of middle-adulthood television viewing the associated risk of AD development, controlling for year of birth, gender, income, and education, increased 1.3 times. Participation in intellectually stimulating activities and social activities reduced the associated risk of developing AD. Findings are consistent with the view that participation in non-intellectually stimulating activities is associated with increased risk of developing AD, and suggest television viewing may be a marker of reduced participation in intellectually stimulating activities.     

Working memory in children: tracing age differences and special educational needs to parameters of a formal model

Parameters of a formal working-memory model were estimated for verbal and spatial memory updating of children. The model proposes interference though feature overwriting and through confusion of whole elements as the primary cause of working-memory capacity limits. We tested 2 age groups each containing 1 group of normal intelligence and 1 deficit group. For young children the deficit was developmental dyslexia; for older children it was a general learning difficulty. The interference model predicts less interference through overwriting but more through confusion of whole elements for the dyslexic children than for their age-matched controls. Older children exhibited less interference through confusion of whole elements and a higher processing rate than young children, but general learning difficulty was associated with slower processing than in the age-matched control group. Furthermore, the difference between verbal and spatial updating mapped onto several meaningful dissociations of model parameters.
