Spatial cognition and motor development: a study of children with spina bifida

The purpose of this study was to examine the relation between motor development and spatial cognition. The sample was 20 children with Spina bifida (M age: 11.4 yr., SD = 1.7) and 20 healthy children as controls (M age: 11.8, SD = 1.8 yr.). An experimental assessment of motor development in spatial cognition in a simulated virtual maze by school-age children is lacking. In this study children with Spina bifida, who were impaired in walking since birth, completed four visuospatial tasks in a small-scale space (Mental Rotation, Water-Level Task, Embedded Figures Test, Visual Short-term Memory Test), and a spatial behaviour and knowledge task in a virtual maze. These children showed poorer performance than children in the control group on most measures. The results are discussed with respect to theoretical implications and further research.     

The link between maternal interaction style and infant action understanding

The present study investigates whether the maternal interaction style is related to 6-month-old infants' action interpretation. We tested 6-month-olds ability to interpret an unfamiliar human action as goal-directed using a modified version of the paradigm used by Woodward, A. L. (1999). Infant's ability to distinguish between purposeful and non-purposeful behaviours. Infant Behavior & Development, 22, 145-160 and Király, I., Jovanovic, B., Prinz, W., Aschersleben, G., & Gergely, G. (2003). The early origins of goal attribution in infancy. Consciousness & Cognition, 12, 732-751. Additionally, all infants and their mothers participated in a free play situation to assess maternal interaction styles as measured by the CARE-Index. According to mothers' distinct interaction styles, infants were divided into three groups. Results suggest that at 6 months of age infants of mothers with a modestly controlling interaction style are better at interpreting a human action as goal-directed than infants of sensitive and relative unresponsive mothers. The ability to understand human action as goal-directed might be a corollary of an adaptive strategy in infancy.     

Development of visual center of mass localization for grasp point selection

Adults assess precisely the center of mass (CM) of single-bodied objects and choose grasping points that span an axis through or close to the center of mass when lifting them. The present study examined how children and adults assess the CM when lifting two-bodied objects (barbells) and how this ability develops. Four- to five-year olds, 6- to 7-year olds, 9- to 11-year olds and adults were required to grasp and lift symmetrically and asymmetrically proportioned miniature barbells and their grasping points were recorded. While the 4- to 5-year olds grasped near the center of the barbell, accuracy of assessing the correct CM improved linearly with age. Although adults grasped close to the CM, their CM determination follows only an approximation of the physical law.     

Fill the Gap! Combining Pragmatic and Prosodic Information to Make Gapping Easy

Two studies investigated the effects of prosody and pragmatic context on off-line and on-line processing of sentences like John greeted Paul yesterday and Ben today. Such sentences are ambiguous between the so-called ‘nongapping’ reading, where John greeted Ben, and the highly unpreferred ‘gapping’ reading, where Ben greeted Paul. In the first experiment, participants listened to dialogues and gave a speeded response as to which reading of an ambiguous target sentence first comes to mind. In the second experiment, they also responded to a visual probe that was presented during the presentation of the ambiguous target. The results show that context and prosody have independent and strong effects on both on-line processing and off-line interpretation of gapping; in the right combination they can make gapping as easy as the normally preferred nongapping reading.     

Pathologischer PC-/Internetgebrauch

An increasing number of people have difficulties in limiting private PC/internet use. Especially, MMORP games (massively multiplayer online role-playing games) like ?World of Warcraft“, action games (?Ego-shooters“) like ?Counterstrike“, surfing and chatting are very time-consuming and for some people can reach a pathological level. When real life disappears from a person’s sight and he is almost permanently focusing on the virtual world, we speak about ?pathological PC/internet use“. The great amount of time spent online for non-work or non-school related purposes is one major symptom. In the AHG clinic Münchwies an in-patient program for pathological PC/internet users has been developed. which focuses on group therapy and is based on integrative cognitive behavioural therapy. Difficulties with motivation, compliance, interaction, attachment organisation and self-structuring of those patients are addressed in addition to the core symptoms. A major goal is to centre the patient’s activities and interests back towards real life in order to establish functioning social-interactive relationships again and to reduce the PC/internet use strictly to professional and necessary private activities.     

Preattentive processing of heart cues and the perception of heart symptoms in congenital heart disease

The present study was aimed at clarifying whether preattentive processing of heart cues results in biased perception of heart sensations in patients with congenital heart disease (ConHD) who are also highly trait anxious. Twenty-six patients with ConHD and 22 healthy participants categorized heart-related (heart rate) or neutral sensations (constant vibration) as either heart or neutral. Both sensations were evoked using a bass speaker that was attached on the chest of the participant. Before each physical sensation, a subliminal heart-related or neutral prime was presented. Biased perception of heart-sensations would become evident by a delayed categorization of the heart-related sensations. In line with the prediction, a combination of high trait anxiety and ConHD resulted in slower responses after a heart-related sensation that was preceded by a subliminal heart cue. Preattentive processing of harmless heart cues may easily elicit overperception of heart symptoms in highly trait anxious patients with ConHD.     

Use of virtual environments to investigate development of spatial behavior and spatial knowledge of school-age children

This review aims to show the potential of using virtual environments in developmental spatial cognition research to advance empirical knowledge and theoretical insight. The facility for easy and economic variations of environmental features, the active, self-determined exploration, and the reliable registration of the navigation behavior using virtual environments allow investigating the development of spatial behavior and spatial knowledge in more detail. As a consequence, a dissociation between spatial behavior and spatial knowledge was observed, leading to the conclusion that spatial context has to be integrated further in any theoretical model regarding development of spatial cognition.     

Psycho-educational evaluations for university students in one clinic

The number of university students requesting services based on the Americans with Disabilities Act for learning disabilities and ADHD-related difficulties has increased, although there are limited reports in the literature describing these evaluations. The current study describes a sample of 140 individuals (59% women) who presented for psycho-educational evaluation at the university psychology clinic. The students were individually administered self-report, cognitive, academic, and attention measures as indicated, and diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). Difficulties with mathematics, attention, and reading concerns were the most frequent presenting complaints. 46 students met criteria for one or more learning disorders and 20 students met criteria for a diagnosis of ADHD. Test scores are summarized and findings compared with the literature.
