Zahnhartsubstanzschäden bei Essstörungen

Eating disorders such as anorexia nervosa and bulimia nervosa lead to several serious physical problems. One possible consequence is acid-related dental erosion. Dental erosion can be identified early and is caused by exogenic (selection of food) and / or endogenic (gastric acid) factors. That is why dentists play an important role in the early identification of eating disorders as well as in the prevention and therapy of dental erosion. They should be important collaborators of psychotherapists. We review characteristic damages to the teeth that are seen in eating disorders as well as preventive and therapeutic interventions. Psychotherapists should be informed about dental problems and preventive strategies to educate their patients.     

Millisecond timing on the Apple Macintosh: Updating Drexel’s MilliTimer

In 1986, we published inBehavior Research Methods, Instruments, & Computers a small library of assembler code for the public domain that permitted accurate millisecond timing for Apple’s Macintosh computer. That version of MilliTimer used the Versatile Interface Adapter chip’s Timer 1 (VIA T1), which is part of the standard Macintosh hardware configuration. The VIA T1, however, is also used by the Sound Manager, and thus the use of sound and accurate millisecond timing were incompatible. We offer for the public domain a new version labeled MilliTimer 2.2, which permits psychologists and other researchers to use the full capabilities of the Macintosh. MilliTimer 2.2 is compatible with popular teaching, research, and clinical tools such as Hyper-Card and MacLaboratory. MilliTimer 2.2 employs the Macintosh Time Manager, which is a part of the Macintosh operating system and is supported by Apple for the 512KE, Plus, SE, and Macintosh II machines. MilliTimer 2.2 is hardware-independent and automatically self-corrects for other operating system activities that also use the Time Manager. The self-correcting function is limited, however, and can result in a nonaccumulating error averaging about ?3 msec. To preserve compatibility with earlier machines that do not contain the Time Manager, a simple mode parameter allows MilliTimer 2.2 to use the older, more accurate timing method.     

Attributional style and self-control behavior in depressed and nondepressed children and their parents

Do the reformulated model of learned helplessness and the self-control model apply to clinically depressed children? Are the related cognitive patterns specific to depression? Are the cognitive deficits associated with depression learned from one's parents? To address these questions this investigation examined three groups of children (ages 8–12) and their parents: nonclinic (n =25),nondepressed clinic (n=22),and depressed clinic (n=15).Children were diagnosed depressed on the basis of Kiddie-SADS interview data. Depressed clinic children self-reported more depression, had a more depressive attributional style, and had more self-control problems. There were more depressed mothers in the clinic than in the nonclinic sample. Depressed clinic children had more depressed mothers than did nondepressed clinic children. There were no differences among the three groups of parents in their cognitive patterns. No relationship was found between the attributional style and self-control behavior of children and their parents.     

Effects of Word Processing and Short-term Memory Deficits on Verbal Learning: Evidence from Aphasia

We report two experiments that investigate the abilities of aphasic subjects with lexical and short-term memory impairments to learn supraspan lists of 10 words. We examined effects of stimulus factors (characteristics of words and lists to be learned) and subject factors (verbal and nonverbal STM span, nature of language impairment). Learning ability was influenced by the imageability and frequency of the words to be learned (Experiment 1) and by the linguistic relationship among words in a list (Experiment 2). Additionally, learning ability was affected by the nature of a subject's word processing deficit (whether it involved semantic and/or phonological processes). Phonological ability was positively associated with learning in both experiments, and semantic ability was associated with learning when words in a list were high in both frequency and imageability (Experiment 1) or were contextually related to one another (Experiment 2). Finally, verbal STM span was positively related to learning performance, but the effect was more pronounced for word span than digit span. These relationships among word processing ability, verbal STM span, and learning ability are discussed with reference to learning in aphasia and to models of learning more generally.     

Contributions of school classification,sex, and ethnic status to adaptive behavior assessment

This study investigated the contributions of school classification (regular, EMR) and sex and ethnic status to domain scores from the Public School Version of the AAMD Adaptive Behavior Scale. For this investigation data were available from a sample of more than 1,600 regular and EMR subjects approximately equally distributed between the sexes among white, black, and Spanish-background subjects from ages 7 to 13. The results replicated earlier findings that domain scores were valid for differentiating among children of different adaptive behavior levels as inferred from school classification status. Ethnic status was not a unique contributor to Part One domain scores when the effects of classification were accounted for. On the Part Two domains, ethnic status was a significant contributor to some domain scores, but not at all age levels. Similarly, sex made few unique contributions to domain scores on Part One of the Scale, but it was a significant factor on some domains of Part Two at some age levels.the author concluded that the Scale was valid for differentiating among pupils assigned to regular and EMR classes from ages 7 to 12. The failure of sex and ethnic status to make contributions to Part One domain scores suggests that there are common expectancies for personal independence and responsibility between boys and girls from different ethnic groups.From the analysis of the contributions of sex and ethnic status to the Part Two domains, the author inferred that difference in environmental tolerance for affective or emotional responses to the school or community environment was a more reasonable explanation than the inference that girls and boys or children grom different cultural backgrounds were inherently different with respect to these behaviors. The Public School Version of the AAMD Adaptive Behavior Scale is valid for assessing adaptive behavior of children in public school and relatively independent of effects attributable to sex or ethnic status.     

Sequential modulations of valence processing in the emotional Stroop task

This study investigated trial-to-trial modulations of the processing of irrelevant valence information. Participants (N = 126) responded to the frame color of pictures with positive, neutral, or negative affective content--a procedure known as an emotional Stroop task (EST). As is typically found, positive and negative pictures delayed responses as compared to neutral pictures. However, the type and extent of this valence-based interference depended on the irrelevant picture valence in the preceding trial. Whereas preceding exposure to negative valence prompted interference from positive and negative pictures, such interference was removed after neutral trials. Following positive pictures, interference from negative but not from positive pictures was observed. We suggest that these sequential modulations reflect automatic self-regulatory selection processes that help to keep the balance between attending to task-relevant information and task-irrelevant information that signals important changes in the environment.     

Development and Validation of a Short Form of the Alabama Parenting Questionnaire

Brief assessments of parenting practices can provide important information about the development of disruptive behavior disorders in children. We examined the factor structure of a widely used assessment of parenting practices, the Alabama Parenting Questionnaire, and produced a 9-item short scale around its three supported factors: Positive Parenting, Inconsistent Discipline and Poor Supervision. The short scale was then validated in independent community samples using confirmatory factor analysis and measures of disruptive behavioral disorders in children. The scale showed good fit to a three-factor model and good convergent validity by differentiating parents of children with disruptive behavioral disorders and parents of children without such disorders. Results indicated that this new measure is an informative tool for researchers and clinicians whom require brief assessments of parenting practices relating to disruptive behavioral disorders in children.     

Assessment of Psychosocial Outcomes in Genetic Counseling Research: An Overview of Available Measurement Scales

The aim of the present paper was to describe and evaluate many of the measurement scales currently used in genetic counseling outcomes research. A team of three researchers reviewed the available literature and selected a variety of validated instruments suitable for measurement of genetic counseling outcomes. There are numerous scales to assess each of the following outcomes among counselees: satisfaction with genetic counseling; knowledge; decision-making; psychological adjustment; coping; perceived personal control; perceptions of disease risk; and family communication about genetic risk. However, the strengths and limitations inherent to each instrument warrant careful consideration prior to implementation. In the genetic counseling context, scale selection should be undertaken with thought directed towards the characteristics of the research sample (e.g. levels of literacy, culture, medical condition), the practicalities of the research setting (e.g. available funding and resources, time restrictions, researcher expertise), the purpose of the research (i.e. the specific aspect of the genetic counseling experience to be studied), and the science underlying the scale (e.g. theoretical framework, psychometric properties).     

A comparison of general and illness-related locus of control in Russians, ethnic German migrants and Germans

General and illness-related locus of control play an immensely important role in the adherence and cooperation of patients in their therapy. Until now, culture-specific aspects of these subjective theories have rarely been investigated. However, in view of the growing proportion of migrants in the German population, they are becoming increasingly significant. In a project supported by the Volkswagenstiftung (Volkswagen Foundation), a total of 607 healthy people were surveyed. The sample includes 307 ethnic German migrants from the successor states of the former Soviet Union (descendents of German origin who had emigrated to Russia during the 18th and 19th centuries) and 300 native Russians in Russia. They were compared with 100 Germans (matched from a previous study). The data were collected using questionnaires entitled "Multidimensional Health Locus of Control (MHLC)" and "Illness-related Locus of Control". The ethnic German migrants differed from the Russian sample in their health beliefs and attitudes towards medicine. However, in the first 18 months after migration, hardly any changes were observed. Fatalistic factors played only a minor role. Locus of health control was associated with beliefs about recovery from myocardial infarcts and tumours. Socio-demographic variables were of varying significance in the individual cultures. Gender influences on health beliefs were different in the subsamples. The level of education had only a minor influence on health attitudes. For those individuals who were acquainted with an ill person, internal factors in treatment of myocardial infarct and external psychosocial factors in cure of cancer played a larger role.     

Learning nonadjacent dependencies: no need for algebraic-like computations

Is it possible to learn the relation between 2 nonadjacent events? M. Pena, L. L. Bonatti, M. Nespor, and J. Mehler (2002) claimed this to be possible, but only in conditions suggesting the involvement of algebraic-like computations. The present article reports simulation studies and experimental data showing that the observations on which Pena et al. grounded their reasoning were flawed by deep methodological inadequacies. When the invalid data are set aside, the available evidence fits exactly with the predictions of a theory relying on ubiquitous associative mechanisms. Because nonadjacent dependencies are frequent in natural language, this reappraisal has far-reaching implications for the current debate on the need for rule-based computations in human adaptation to complex structures.
