Neuropharmacology of verbal perseveration.

Functional analysis and treatment of verbal perseverations displayed by an adult with autism.

The function of perseverative speech for an adult man who had been diagnosed with autism and mental retardation was examined. Results showed that verbal perseverations were maintained by social attention. An intervention consisting of differential reinforcement of appropriate verbal responses and extinction of perseverative verbal responding was effective in decreasing verbal perseverations.

Possible Roles of the Dominant Uncinate Fasciculus in Naming Objects: A Case Report of Intraoperative Electrical Stimulation on a Patient with a Brain Tumour

How the dominant uncinate fasciculus (UF) contributes to naming performance is uncertain. In this case report, a patient with an astrocytoma near the dominant UF was given a picture-naming task during intraoperative electrical stimulation in order to resect as much tumourous tissues as possible without impairing the dominant UF function. Here we report that the stimulations with the picture-nam...

Selective information use and perseveration in the search behavior of infants and young children.

Two experiments examined the early development of selective information use in search. The first experiment tested 9- and 16-month-olds on a modification of Piaget's Stage IV object permanence task. It examined infants' use of information from previous experiences with an object (prior information) and from the most recent hiding (current information) to locate a hidden object. In the second ex...
