A complex sequence learning task was used to determine if the type of coding acquired through physical practice (PP), observation of the stimulus (Obs-S), or observation of stimulus and action (Obs-SA) differs between conditions and whether the type of observation influences subsequent learning of the task when physical practice was permitted.

This paper offers a detailed analysis of the English suffix-ee (employee, escapee, refugee, etc.) based on 1500 naturally-occurring tokens of some 500 word types. The data suggest that formation of nouns in-ee is moderately but genuinely productive, and that analyses based on the syntactic argument structure of the stem verb are unsatisfactory. Instead,(More)
Hikosaka et al. (1999) proposed that sequential movements are acquired in independent visual-spatial and motor coordinate systems with coding initially represented in visual-spatial coordinates, and later after extended practice in motor coordinates. One aspect of sequence learning that has not been systematically studied, however, is the question of(More)
We investigated the practice-effects on motor skill transfer and the associated representational memory changes that occur during the within-practice and between-practice phases. In two experiments, participants produced extension-flexion movements with their dominant right arm for a limited or prolonged practice session arranged in either a single- or(More)
Cerebral side effects of therapy with glucocorticoids include mental alterations and behavioral disturbances such as nervousness, insomnia, changes in mood or psychological state and psychopathies of manic-depressive or schizophrenic type. We have investigated the effects of glucocorticoids, anabolic/androgenic steroids and the 5-alpha-reductase inhibitor(More)
We examined the influence of visual context information on skilled motor behaviour and motor adaptation in basketball. The rules of basketball in Europe have recently changed, such that that the distance for three-point shots increased from 6.25 m to 6.75 m. As such, we tested the extent to which basketball experts can adapt to the longer distance when a)(More)
PURPOSE This prospective study explores the efficacy of a combined approach by intranasal microsurgical dacryocystorhinostomy and fiberglass endoillumination of the tear passage for difficult cases of lacrimal sac or nasolacrimal duct obstruction. METHODS Microscopic dacryocystorhinostomy was performed in 67 patients with lacrimal obstruction and for(More)
Important information on the cornea can be obtained by ultrasound biomicroscopy. Intrastromal corneal scars, internal corneal adaptation after penetrating injuries or keratoplasties, corneal dystrophies and other lesions can be demonstrated. The acoustical examination is in competition with optical methods. It has advantages in opaque optical media and in(More)
BACKGROUND The aim of the study was to evaluate results of visual acuity and binocularity and complications after cataract surgery with primary capsular bag-fixated IOL implantation in children. MATERIALS AND METHODS Thirty-three children [mean age (+/- SEM) 6.9 +/- 2.9 years, range 3-12 years] accounting for 43 eyes, were examined before and after(More)
