Objectives: The prospective longitudinal Mannheim Study of Children at Risk followed the development of children from the age of 2 years up to the age of 8 years. Are there differences between the developmental risk load in toddlers (psychopathology, cognition, motor or neurological development. and educational differences) who suffer from a hyperactive disorder at age 8 and that of undisturbed children of the same age? Are there specific harbingers of hyperkinetic disorders for the group concerned? Methods: In terms of their developmental risk load at the age of 2 years, 26 primary school children with hyperkinetic disorders were compared to 241 healthy primary school children, as well as to 25 children of the same age with emotional disturbances and 30 children of the same age with socially disruptive behavior. Results: A significant combination of predictors of later hyperkinetic disorders at primary school age proved to be increased fidgetiness and irritability, as well as a reduced language comprehension, at the age of two. Conclusions: The predictive value of symptoms in early childhood for later hyperkinetic disorder in children of primaryschool age is higher than that of symptoms assessed in infancy, which although expected is without relevant specificity.
Objectives: Are there any differences (organic, psychosocial, psychopathological, cognitive or educational, respectively differences in the motor or neurological development) between infants who later on at the age of 8 years suffer from a hyperactive disorder and those who later on at the same age are undisturbed? Are there specific harbingers for hyperactive disorders in the group concerned? Methods: With regard to their developmental risk load at the age of 3 months, 26 primary school children with hyperactive disorders were compared with 241 healthy children, 25 children with emotional disturbances, and 30 children with socially disruptive behaviour, all of the same age. Results: Identified as the most important predictors for the onset of hyperactive disorders were a reduced birth weight, the mother's origin from a shattered family, early contact impairments on the part of the child, and the mother's neglect of the infant. Conclusions: Altogether, however, the prediction of later hyperactivity in primary school children on the basis of salient features in the infant children remains unsatisfactory and unspecific.
Spatial numerical associations (SNAs) are prevalent yet their origin is poorly understood. We first consider the possible prime role of reading habits in shaping SNAs and list three observations that argue against a prominent influence of this role: (1) directional reading habits for numbers may conflict with those for non-numerical symbols, (2) short-term experimental manipulations can overrule the impact of decades of reading experience, (3) SNAs predate the acquisition of reading. As a promising alternative, we discuss behavioral, neuroscientific, and neuropsychological evidence in support of finger counting as the most likely initial determinant of SNAs. Implications of this "manumerical cognition" stance for the distinction between grounded, embodied, and situated cognition are discussed.
We investigated the mental rehearsal of complex action instructions by recording spontaneous eye movements of healthy adults as they looked at objects on a monitor. Participants heard consecutive instructions, each of the form "move [object] to [location]''. Instructions were only to be executed after a go signal, by manipulating all objects successively with a mouse. Participants re-inspected previously mentioned objects already while listening to further instructions. This rehearsal behavior broke down after 4 instructions, coincident with participants' instruction span, as determined from subsequent execution accuracy. These results suggest that spontaneous eye movements while listening to instructions predict their successful execution.

A growing literature has suggested that processing of visual information presented near the hands is facilitated. In this study, we investigated whether the near-hands superiority effect also occurs with the hands moving. In two experiments, participants performed a cyclical bimanual movement task requiring concurrent visual identification of briefly presented letters. For both the static and dynamic hand conditions, the results showed improved letter recognition performance with the hands closer to the stimuli. The finding that the encoding advantage for near-hand stimuli also occurred with the hands moving suggests that the effect is regulated in real time, in accordance with the concept of a bimodal neural system that dynamically updates hand position in external space.
The embodied cognition framework suggests that neural systems for perception and action are engaged during higher cognitive processes. In an event-related fMRI study, we tested this claim for the abstract domain of numerical symbol processing: is the human cortical motor system part of the representation of numbers, and is organization of numerical knowledge influenced by individual finger counting habits? Developmental studies suggest a link between numerals and finger counting habits due to the acquisition of numerical skills through finger counting in childhood. In the present study, digits 1 to 9 and the corresponding number words were presented visually to adults with different finger counting habits, i.e. left- and right-starters who reported that they usually start counting small numbers with their left and right hand, respectively. Despite the absence of overt hand movements, the hemisphere contralateral to the hand used for counting small numbers was activated when small numbers were presented. The correspondence between finger counting habits and hemispheric motor activation is consistent with an intrinsic functional link between finger counting and number processing.

There is much recent interest in the idea that we represent our knowledge together with the sensory and motor features that were activated during its acquisition. This paper reviews the evidence for such "embodiment" in the domain of numerical cognition, a traditional stronghold of abstract theories of knowledge representation. The focus is on spatial-numerical associations, such as the SNARC effect (small numbers are associated with left space, larger numbers with right space). Using empirical evidence from behavioral research, I first describe sensory and motor biases induced by SNARC, thus identifying numbers as embodied concepts. Next, I propose a hierarchical relationship between grounded, embodied, and situated aspects of number knowledge. This hierarchical conceptualization helps to understand the variety of SNARC-related findings and yields testable predictions about numerical cognition. I report several such tests, ranging from cross-cultural comparisons of horizontal and vertical SNARC effects (Shaki and Fischer in J Exp Psychol Hum Percept Perform 38(3): 804-809, 2012) to motor cortical activation studies in adults with left- and right-hand counting preferences (Tschentscher et al. in NeuroImage 59: 3139-3148, 2012). It is concluded that the diagnostic features for each level of the proposed hierarchical knowledge representation, together with the spatial associations of numbers, make the domain of numerical knowledge an ideal testing ground for embodied cognition research.
