How reading changes letter representations: a double dissociation using orthographically distinct scripts in India

Automatic Reading of Cursive Scripts Using Human

This paper presents a model for reading cursive script which has an architecture inspired by a reading model and which is based on perceptual concepts. We limit the scope of our study to the oo-line recognition of isolated cursive words. First of all, we justify why we chose McClelland & Rumelhart's reading model as the inspiration for our system. A brief resum e of the method's behavior is pre...

A double-dissociation in infants' representations of object arrays.

Previous studies show that infants can compute either the total continuous extent (e.g. Clearfield, M.W., & Mix, K.S. (1999). Number versus contour length in infants' discrimination of small visual sets. Psychological Science, 10(5), 408-411; Feigenson, L., & Carey, S. (2003). Tracking individuals via object-files: evidence from infants' manual search. Developmental Science, 6, 568-584) or the ...

Motor Extinction in Distinct Reference Frames: A Double Dissociation

OBJECTIVE Test the hypothesis that right hemisphere stroke can cause extinction of left hand movements or movements of either hand held in left space, when both are used simultaneously, possibly depending on lesion site. METHODS 93 non-hemiplegic patients with acute right hemisphere stroke were tested for motor extinction by pressing a counter rapidly for one minute with the right hand, left ...

Evidence of Double Dissociation in Auditory Agnosia: Implications for Rehabilition

Visuoperceptual deficits in letter-by-letter reading?

A longstanding and controversial issue concerns the underlying mechanisms that give rise to letter-by-letter (LBL) reading: while some researchers propose a prelexical, perceptual basis for the disorder, others postulate a postlexical, linguistic source for the problem. To examine the nature of the deficit underlying LBL reading, in three experiments, we compare the performance of seven LBL rea...
