Sunderland, Alan; Wilkins, Leigh; Dineen, Rob; Dawson, Sophie E. – Brain and Cognition, 2013
Impaired tool related action in ideomotor apraxia is normally ascribed to loss of sensorimotor memories for habitual actions (engrams), but this account has not been tested against a hypothesis of a general deficit in representation of hand-object spatial relationships. Rapid reaching for familiar tools was compared with reaching for abstract…

Stock, Oliver; Roder, Brigitte; Burke, Michael; Bien, Siegfried; Rosler, Frank – Journal of Cognitive Neuroscience, 2009
The present study used functional magnetic resonance imaging to delineate cortical networks that are activated when objects or spatial locations encoded either visually (visual encoding group, n = 10) or haptically (haptic encoding group, n = 10) had to be retrieved from long-term memory. Participants learned associations between auditorily…

Chokron, Sylvie; Colliot, Pascale; Atzeni, Thierry; Bartolomeo, Paolo; Ohlmann, Theophile – Brain and Cognition, 2004
Eighty blindfolded healthy female subjects participated in an active and a passive straight-ahead pointing task to study the estimation of the subjective sagittal middle in the presence or absence of an active haptic exploration. Subjects were to point straight-ahead with their left or right index finger starting from different right- or…

Dikowski, Timothy J. – 1994
This practicum was designed to remediate handwriting skills in school-aged children who displayed visual-motor deficiencies that affect mechanical skills. Practicum goals were to: (1) identify and diagnose children with handwriting delays; (2) involve school and parent interaction by involving them with pre- and post-program assessment; (3)…
