Arithmetical Word Problem Solving After Frontal Lobe Damage

L. Fasotti

Patients with frontal brain lesions show a striking disorder in arithmetical word problem solving; they tend to give impulsive responses, skipping one or more of the essential solution steps. The research presented here along with its implications for treatment was conducted by the Dutch Institute f
