The best of both worlds? General principles of psychopathology in personalized assessment.

A complex systems approach to psychopathology proposes that general principles lie in the dynamic patterns of psychopathology, which are not restricted to specific psychological processes like symptoms or affect. Hence, it must be possible to find general change profiles in time series data of fully personalized questionnaires. In the current study, we examined general change profiles in personalized self-ratings and related these to four measures of treatment outcome (International Symptom Rating, 21-item Depression Anxiety and Stress Scale, daily symptom severity, and self-reflective capacity).

Complexity theory of psychopathology.

There is a renewed interest for complex adaptive system approaches that can account for the inherently complex and dynamic nature of psychopathology. Yet a theory of psychopathology grounded in the principles of complex adaptive systems is lacking. Here, we present such a theory based on the notion of dynamic patterns: patterns that are formed over time.

Identifying Determinants of Dyslexia: An Ultimate Attempt Using Machine Learning.

Research based on traditional linear techniques has yet not been able to clearly identify the role of cognitive skills in reading problems, presumably because the process of reading and the factors that are associated with reading reside within a system of multiple interacting and moderating factors that cannot be captured within traditional statistical models. If cognitive skills are indeed indicative of reading problems, the relatively new nonlinear techniques of machine learning should make better predictions. The aim of the present study was to investigate whether cognitive factors play any role in reading skill, questioning (1) the extent to what cognitive skills are indicative of present reading level, and (2) the extent to what cognitive skills are indicative of future reading progress.

Does popularity determine who leads in a dyadic cooperative task? Subtle differences between children with and without developmental disabilities.

Background: Popular indivuals are usually academically high achiveving and also often leaders. Children with developmental disabilities are usually not popular among their peers. In dyadic cooperative tasks, the popular member is often the leader, as shown by self-reports and observational research.

Dynamic Patterns of Three Staff Members Interacting with a Client with an Intellectual Disability and Challenging Behavior: Suggestions for Coaching.

In relationships between staff members and clients with intellectual disabilities (ID) and challenging behavior (CB) it is important to study their bidirectional dynamic interactions. In the present study three staff members were recorded on video during a daily bathing session with the same client with ID and CB. The video codings were analyzed using Cross Recurrence Quantification Analysis (CRQA) and based on the categories of Leary and Banjamin's interpersonal models.

Dyslexie font does not benefit reading in children with or without dyslexia.

In two experiments, the claim was tested that the font "Dyslexie", specifically designed for people with dyslexia, eases reading performance of children with (and without) dyslexia. Three questions were investigated. (1) Does the Dyslexie font lead to faster and/or more accurate reading? (2) Do children have a preference for the Dyslexie font? And, (3) is font preference related to reading performance? In Experiment 1, children with dyslexia (n = 170) did not read text written in Dyslexie font faster or more accurately than in Arial font.

Differential relationships between language skills and working memory in Turkish-Dutch and native-Dutch first-graders from low-income families.

In the Netherlands, Turkish-Dutch children constitute a substantial group of children who learn to speak Dutch at the age of four after they learned to speak Turkish. These children are generally academically less successful. Academic success appears to be affected by both language proficiency and working memory skill.

Cooperative Learning and Interpersonal Synchrony.

Cooperative learning has been shown to result in better task performance, compared to individual and competitive learning, and can lead to positive social effects. However, potential working mechanisms at a micro level remain unexplored. One potential working mechanism might be the level of interpersonal synchrony between cooperating individuals.

Progress in reading and spelling of dyslexic children is not affected by executive functioning.

Although poor reading and spelling skills have been associated with weak skills of executive functioning (EF), its role in literacy is not undisputed. Because EF has different theoretical underpinnings, methods of analysis and of assessing, it has led to varying and often contrasting results in its effects in children with dyslexia. The present study has two goals.

Verbal interactional dominance and coordinative structure of speech rhythms of staff and clients with an intellectual disability.

Social interactions between staff and clients with an intellectual disability contain synchronized turn-taking patterns. Synchrony can increase rapport and cooperation between individuals. This study investigated whether verbal interactional dominance and balance, an indication of attunement between staff and clients with ID, are associated with synchrony of turn-taking patterns during staff-client interactions and whether the level of dominance and balance is related to the observed quality of the social interactions.

Dyslexic and skilled reading dynamics are self-similar.

The shape of a word pronunciation time distribution supplies information about the dynamic interactions that support reading performance. Speeded word-naming pronunciation and response time distributions were collected from 20 sixth grade Dutch students with dyslexia and 23 age-matched controls. The participants' pronunciation times were modeled and contrasted with a lognormal inverse power-law mixture distribution.

Evaluating staff training: taking account of interactions between staff and clients with intellectual disability and challenging behaviour.

Background: Hastings (2010) has recently emphasised 3 aspects in the training of staff who serve clients with mild to moderate intellectual disability and challenging behaviour (CB): Staff attitudes, self-awareness, and clients' perspectives. This study investigates whether programs include these aspects.

Method: A systematic search yielded 11 relevant articles.

Emotional intelligence, emotions, and feelings of support staff working with clients with intellectual disabilities and challenging behavior: an exploratory study.

Working with clients who show challenging behavior can be emotionally demanding and stressful for support staff, because this behavior may cause a range of negative emotional reactions and feelings. These reactions are of negative influence on staff wellbeing and behavior. Research has focused on negative emotions of staff.

Writing about stress: the impact of a stress-management programme on staff accounts of dealing with stress.

Background: Helping staff serving clients with intellectual disability and challenging behaviour to cope with stress has implications for their own well-being and for the lives of those they support.

Method: This study examined staff members' views of stress and the effectiveness of a stress-management intervention. Effectiveness was assessed using written assignments regarding stress management, and changes in views presented were tested in a pre- and post-test control group design.

Quantitative and qualitative processes of change during staff-coaching sessions: an exploratory study.

Staff training is one of the interventions that managers can embed in their organizations to help staff improve their professional competences related to challenging behaviour of clients with intellectual disabilities. Individual coaching adds learning opportunities that are feasible but difficult to achieve in an in-service setting. In the present study, we have followed the coaching process of three staff members.

Predicting early spelling difficulties in children with specific language impairment: a clinical perspective.

This study focused on the precursors of spelling difficulties in first grade for children with specific language impairment (SLI). A sample of 58 second-year kindergartners in The Netherlands was followed until the end of first grade. Linguistic, phonological, orthographic, letter knowledge, memory, and nonverbal-reasoning skills were considered as precursors, as was spelling level at an earlier point in time.

Measuring staff behavior towards clients with ID and challenging behavior: further psychometric evaluation of the Staff-Client Interactive Behavior Inventory (SCIBI).

Recently, the Staff-Client Interactive Behavior Inventory (SCIBI) was developed, measuring both interpersonal and intrapersonal staff behavior in response to challenging behavior in clients with ID. The aim of the two studies presented here was first to confirm the factor structure and internal consistency of the SCIBI and second to demonstrate its convergent validity. In the first study, a total of 265 support staff members, employed in residential and community services, completed the SCIBI for 62 clients with ID and challenging behavior.

The relationship among attributions, emotions, and interpersonal styles of staff working with clients with intellectual disabilities and challenging behavior.

Several studies have tested Weiner's model, which suggests a relationship among causal attributions regarding challenging behavior (CB), emotions, and helping behavior of staff. No studies have focused on interpersonal styles. The goals of this study were to investigate the influence of type of CB on attributions, emotions and interpersonal style of staff, the relationships among staff attributions, emotions, and interpersonal style, and the mediating function of emotions in the relation between attributions and interpersonal style.

Specific Language Impairment affects the early spelling process quantitatively but not qualitatively.

The present study investigated whether children with Specific Language Impairment (SLI) need a special spelling education program, by examining whether the early spelling of children with SLI is quantitatively and qualitatively different from the spelling of typically developing children. Two groups of first grade children participated: 39 children with a typical language development between the age of 73 and 88 months, and 59 children with SLI between the age of 71 and 97 months. The results indicated that children with SLI do have a quantitative delay in both grapheme knowledge and spelling during first grade.

Characteristics of early spelling of children with Specific Language Impairment.

Unlabelled: The present study investigated active grapheme knowledge and early spelling of 59 first grade children with Specific Language Impairment (SLI). Speed, nature, and knowledge transfer of spelling acquisition were taken into account. Four orthographic characteristics that influence early spelling, namely, 'Type of Grapheme', 'Grapheme Position', 'Number of Graphemes', and 'Word Structure' were examined at the middle and at the end of first grade.

Predicting word decoding and word spelling development in children with Specific Language Impairment.

Unlabelled: This longitudinal investigation on Dutch children with Specific Language Impairment (SLI) aimed at determining the predictive value of statistically uncorrelated language proficiencies on later reading and spelling skills in Dutch. Language abilities, tested with an extensive test battery at the onset of formal reading instruction, were represented by four statistically uncorrelated factors: lexical-semantic abilities, auditory perception, verbal-sequential processing, and speech production. All factors contributed significantly to the prediction of word reading and spelling development seven months later.

Contemporary theories of 1/f noise in motor control.

1/f noise has been discovered in a number of time series collected in psychological and behavioral experiments. This ubiquitous phenomenon has been ignored for a long time and classical models were not designed for accounting for these long-range correlations. The aim of this paper is to present and discuss contrasted theoretical perspectives on 1/f noise, in order to provide a comprehensive overview of current debates in this domain.

Semantic categorization and reading skill across Dutch primary grades: development yes, relationship no.

In the present study, the development of semantic categorization and its relationship with reading was investigated across Dutch primary grade students. Three Exemplar-level tasks (Experiment 1) and two Superordinate-level tasks (Experiment 2) with different types of distracters (phonological, semantic and perceptual) were administered to assess semantic categorization skills. Reading was measured with a standardized word-reading test.

Semantic categorization: a comparison between deaf and hearing children.

Unlabelled: Learning to read is a major obstacle for children who are deaf. The otherwise significant role of phonology is often limited as a result of hearing loss. However, semantic knowledge may facilitate reading comprehension.

1/f scaling in movement time changes with practice in precision aiming.

When people perform repeated goal-directed movements, consecutive movement durations inevitably vary over trials, in poor as well as in skilled performances. The well-established paradigm of precision-aiming is taken as a methodological framework here. Evidence is provided that movement variability in closed tasks is not a random phenomenon, but rather shows a coherent temporal structure, referred to as 1/f scaling.
