Sustained behavioral contrast in children1

Laterality in Prematurely -born Children1

The study examined the relationship between perinatal stress and decreased right handedness and decreased left cerebral dominance for speech with 215 children born prematurely, followed from birth, and tested at age 5. Results indicated that neither hand preference nor hand performance correlated with degree of perinatal stress and that eye preference was associated with perinatal stress though...

Mother Merge and Her Children1

This paper examines in detail the proposition that a set of fundamental syntactic relations (domination, sisterhood, c-command, etc) can be founded in the computational operation Merge, itself taken to be fundamental and indispensable. In doing this, it pursues one aspect of minimalist methodology in an unusually rigorous fashion. The outcome of the investigation is that Chomsky’s initial appro...

Chronopharmacology of High-Dose Busulfan in Children1

In bone marrow transplantation, high-dose busulfan is given p.o., usu ally every 6 h over 4 consecutive days. Since this repeated administration might alter busulfan disposition, fluctuations in busulfan plasma levels were studied over the 4-day treatment period in 21 children (median age, 5 years) with malignant solid tumors. In addition, urinary excretion of unchanged busulfan was measured ev...

The Development of Attention in Children1

Behavioral contrast in competitive and noncompetitive environments.

Three experiments examined the effects of opportunities for an alternative response (drinking) on positive behavioral contrast of rats' food-reinforced bar pressing. In both Experiments 1 and 2 the baseline multiple variable-interval schedules were rich (variable interval 10-s), and contrast was examined both with and without a water bottle present. In Experiment 1, the rats were not water depr...
