The roles of verbal short-term and working memory were examined in a sample of children with Williams syndrome (mean chronological age 10 years, 2 months) and a sample of grammar-matched children who are developing normally. Forward digit span, nonword repetition, and backward span were all found to be correlated with receptive grammatical ability in the(More)
A telestimulator has been constructed which is suitable for mounting on the heads of medium-sized Macaca mulatta or larger primates. It differs from previous units in that the battery supply is continuously recharged from ambient light by means of solar cells. The system features remote control of all stimulus parameters, constant current output, and remote(More)
