Profiles of Everyday Executive Function in Acquired and Developmental Disorders

The current study focused on the early development of inhibitory control in 5- to 7-year-old children attending kindergarten in two Eastern-European countries, Romania and Russia. These two countries share many aspects of child-rearing and educational practices, previously documented to influence the development of inhibitory control. Using the Lurian-based developmental approach offered by the Developmental Neuropsychological Assessment battery, the study aimed to contribute to cross-cultural developmental neuropsychology by exploring (a) early interrelationships between subcomponents of inhibitory control (response suppression and attention control) and generative fluency (verbal and figural) in these two cultures, as well as (b) the predictive value of external factors (culture and maternal education) and individual differences (age, gender, nonverbal intelligence, trait anxiety) on inhibitory control and fluency outcomes in children from both countries. First, findings in both culture samples suggest that even at this young age, the construct of inhibitory control cannot be considered a unitary entity. Second, differences in maternal education were not predictive of either inhibitory control or fluency scores. However, children’s attention control performance varied as a function of culture, and the direction of these cultural effects differed by whether the target outcome involved performance accuracy versus efficiency as an output. Findings also confirmed the previously documented intensive developmental improvement in preschoolers’ inhibitory control during this period, influencing measures of response suppression and particularly attention control. Finally, the results further stress the importance of individual differences effects in trait anxiety on attention control efficiency across cultures.     

Attention and social functioning in children with malformations of cortical development and stroke

Attention and social functioning and their interrelationships have not been routinely examined in children with early brain insult (EBI). This study aimed to describe attention and social functioning in children with two types of EBI: malformations of cortical development (MCD) and stroke. Children diagnosed with MCD (n?=?14, 6 males) or stroke (n?=?14, 8 males) aged 8 to 14 years (M?=?12 years 11 months) completed neuropsychological assessments to examine attention processes. Primary caregivers completed a questionnaire to assess executive components of children's attention and teachers completed a questionnaire to measure children's social functioning. Brain scans (MRI or CT) were coded by a pediatric neuroradiologist. Higher rates of impairments in attention and social function were found in children with EBI compared with normative expectations. Children with MCD experienced more global and clinically significant levels of impairment than children with stroke; though impairments were present in both groups. A strong association between executive components of attention and social function was observed. In addition, complex attention processes were associated with social function. The findings emphasize the reciprocity between attention, behavior and social outcomes, and the vulnerability of social function following EBI.     

A comparison of working memory profiles in children with ADHD and DCD

The main objective of present study was to investigate whether the patterns of working memory performance differ as a function of attention and motor difficulties, and whether children with ADHD and DCD could be reliably discriminated on the basis of their memory deficits. A related aim was to investigate the link between their working memory profiles and academic attainment. Fifty children with ADHD-Combined, 55 children with DCD, and an age-matched group of 50 typically developing children with average working memory were assessed on standardized measures of working memory, IQ, and academic attainment (reading, spelling, comprehension, and math). The normal controls performed significantly better than both clinical groups on all working memory tests. Specific patterns emerged in the memory profile of the clinical groups: The children with DCD had a depressed performance in all working memory tests, with particularly low scores in visuospatial memory tasks; children with ADHD performed within age-expected levels in short-term memory but had a pervasive working memory deficit that impacted both verbal and visuospatial domains. The clinical groups could reliably be discriminated on the basis of their short-term memory scores. Their learning profiles were similar. It is possible that the working memory profiles of the children with ADHD and DCD are influenced by distinct underlying cognitive mechanisms, rather than a general neurodevelopmental delay. Despite these distinctive patterns of memory performance, both clinical groups performed similarly on academic attainments, suggesting that memory may underlie learning difficulties, independent of related clinical disorders.     

Central executive involvement in children's spatial memory

Previous research with adults found that spatial short-term and working memory tasks impose similar demands on executive resources. We administered spatial short-term and working memory tasks to 8- and 11-year-olds in three separate experiments. In Experiments 1 and 2 an executive suppression task (random number generation) was found to impair performances on a short-term memory task (Corsi blocks), a working memory task (letter rotation), and a spatial visualisation task (paper folding). In Experiment 3 an articulatory suppression task only impaired performance on the working memory task. These results suggest that short-term and working memory performances are dependent on executive resources. The degree to which the short-term memory task was dependent on executive resources was expected to be related to the amount of experience children have had with such tasks. Yet we found no significant age-related suppression effects. This was attributed to differences in employment of cognitive strategies by the older children.     

Brief communications from the edge: psychotherapy with challenging adolescents

Issues of technique in work with adolescents who, if adult, would attract a forensic label, are discussed with especial focus on interpretation and countertransference in the light of primitive anxieties and body-based mechanisms of defence. The therapist as 'new object' and 'developmental object' is explored. The case study of Matthew - a mid-adolescent who has abused a younger child, is delinquent, seeks violent and dangerous situations and experiences outbursts of aggression - is used as illustration throughout.     

Some Oedipal problems in work with adopted children and their parents

This paper has two main theses. Firstly that Oedipal material is a particular feature of clinical work with adopted children; secondly, that the concept of developmental deficit, and not only that of psychic defence, is essential to an understanding of this aspect of the work with adopted children and their families. Three levels are distinguished at which Oedipal difficulties are manifest: the first two within the individual child and the third within the triangle formed by the child, his adoptive parents and the child psychotherapist. Some consideration is given to the limitations of a conventional treatment framework for containing the powerful Oedipal dynamic forces at play when an adopted child is a patient in individual psychotherapy. Dieser Artikel hat zwei Hauptthesen. Erstens, dass ödipales Material ein besonderes Merkmal der klinischen Arbeit mit adoptierten Kindern ist; zweitens dass das Konzept eines Entwicklungsdefizit, und nicht nur das eines psychischen Abwehrmechanismus, für das Verstehen dieses Aspekts der Arbeit mit adoptierten Kindern und ihren Familien unerlässlich ist. Es werden drei Stufen differenziert, in denen sich ödipale Schwierigkeiten manifestieren: die ersten zwei innerhalb des Kindes und die dritte innerhalb des Dreiecks, das vom Kind, seinen Adoptiveltern und dem Kindertherapeuten gebildet wird. Es werden überlegungen bezüglich der Grenzen des konventionellen Behandlungsrahmens angestellt, inwieweit er die mächtigen ödipalen dynamischen Kräfte, die im Spiel sind, 'containen' kann, wenn ein adoptiertes Kind Patient in individueller Psychotherapie ist. Dans son texte, l'auteur développe deux thèses principales: d'abord, que le matériel ?dipien est d'une importance particulière dans le traitement d'enfants adoptés; et, ensuite, que le concept de trouble déficitaire du développement, en plus de celui de défense psychique, est essentiel pour comprendre cet aspect de la prise en charge d'enfants adoptés et de leur famille. L'auteur distingue trois niveaux auxquels se manifestent la problématique ?dipienne?:?les deux premiers concernent l'enfant lui-même en tant qu'individu, le troisième renvoie au triangle composé de l'enfant, de ses parents adoptifs et du psychothérapeute. Certaines limitations imposées par le cadre thérapeutique traditionnel sont ensuite explorées, notamment par rapport à la possibilité de contenir la puissante dynamique ?dipienne évoquée dès qu'un enfant adopté est pris en psychothérapie individuelle. Questo articolo sostiene due tesi principali. La prima e' che il materiale edipico e' una caratteristica particolare del lavoro clinico con bambini adottati; la seconda e' che il concetto di deficit evolutivo, e non solo quello di difesa psichica, e' essenziale per capire questo aspetto del lavoro con bambini adottati e le loro famiglie. Vengono distinti tre livelli in cui si manifestano le difficolta' edipiche: i primi due all'interno del singolo bambino, il terzo all'interno del triangolo formato dal bambino, dai suoi genitori adottivi e dallo psicoterapeuta infantile. Vengono fatte alcune considerazioni sulle limitazioni che il contesto terapeutico convenzionale ha nel contenere le potenti forze dinamiche edipiche in gioco quando un bambino adottato diventa paziente in terapia individuale.     

Is the impaired N170 print tuning specific to developmental dyslexia? A matched reading-level study with poor readers and dyslexics

Left N170 print tuning has been associated with visual expertise for print and has been reported to be impaired in dyslexics, using age matched designs. This is the first time N170 print tuning has been compared in adult dyslexics and adult poor readers, matched in reading level. Participants performed a lexical decision task using both word-like stimuli and symbol strings. In contrast to dyslexics, poor readers displayed similar N170 tuning to control expert readers, suggesting that impaired N170 specialization is a hallmark of developmental dyslexia. Our findings provide electrophysiological support for dyslexia being the result of abnormal specialization of the left occipito-temporal areas involved in the expert processing of print. Furthermore, as shown by correlations data and in accordance with the phonological mapping deficit theory, the impaired visual expertise for print described in dyslexics may have been caused by their core phonological deficits.     

Mental rotation performance and the effect of gender in fourth graders and adults

The DSM-IV implicitly assumes that development is uniform across ability domains, which implies that relationships between ability measures do not differ across development. We assessed whether correlations between measures of nine ability constructs differed across samples of children aged 3 – 5 (n = 117), 6 – 8 (n = 116), 9 – 11 (n = 124) and 12 – 14 years (n = 92). LISREL analyses show that correlations in each age group differ from those of each other age group. Parallel analyses indicate that the latent structure of ability differs across age groups. We conclude that shared maturational processes, including changes in the connectivity of neural systems, are responsible for decreasingly and increasingly strong relationships between some ability measures.     

Developmental trajectory of intersubjectivity in the second and third year of life: Study of fixed-population and random-individual effects

Colwyn Trevarthen claimed that babies have an intrinsic motivation to communicate and engage with others that he called intersubjectivity. Around the ninth month of life, this motivation changes and passes from person-to-person dyadic (primary intersubjectivity) to triangulate a person–person–object relationship (secondary intersubjectivity). Despite the scientific consensus on this developmental leap, few empirical studies explore the trajectory of this more complex form of intersubjectivity between the second and third year of life. One hundred and fifteen free play sessions from 27 mother–child dyads (13 girls and 14 boys) between 9 and 37 months were filmed and were categorized based on the Level of Intersubjective Attunement Scale. The data were analysed using a linear mixed-effects model. Results show both a population trajectory of the levels of intersubjective attunement and random individual differences. We discuss these results in relation to the binomial typical developmental route and interindividual variability.
