During the second year of life, infants exhibit a video deficit effect. That is, they learn significantly less from a televised demonstration than they learn from a live demonstration. We predicted that repeated exposure to televised demonstrations would increase imitation from television, thereby reducing the video deficit effect. Independent groups of 6- to 18-month-olds were exposed to live ...

Attention deficit hyperactivity disorder (ADHD) is characterized by inattention, impulsivity, and hyperactivity mediated by frontal-striatal-cerebellar dysfunction. These circuits support implicit learning of perceptual-motor sequences but not visual-spatial context. ADHD and control children performed the Alternating Serial Reaction Time (ASRT) task, a measure of sequence learning, and the Con...

Difficulties with learning mathematics and to read have for a long time been categorised into diagnostic categories like dyscalculia dyslexia. This categorization has based on ideas that some core deficits underlie cause the difficulties. However, no clear sufficient deficit found these difficulties qualitative differences identified distinguishing those assigned diagnoses from people not – thu...

Recent studies in our laboratory have shown that PCP (phencyclidine) and d-amphetamine induce a cognitive deficit in rats, in a paradigm of potential relevance for the pathology of schizophrenia. Atypical, but not classical antipsychotics and the anticonvulsant, lamotrigine have been shown to prevent a selective reversal learning deficit induced by PCP. In contrast, only haloperidol reversed th...
