The effect of level of processing on perceptual and conceptual priming: control versus closed-head-injured patients.

Twenty-four closed-head-injured (CHI) and 24 control participants studied two word lists under shallow (i.e., nonsemantic) and deep (i.e., semantic) encoding conditions. They were then tested on free recall, perceptual priming (i.e., perceptual partial word identification) and conceptual priming (i.e., category production) tasks. Previous findings have demonstrated that memory in CHI is characterized by inefficient conceptual processing of information. It was thus hypothesized that the CHI participants would perform more poorly than the control participants on the explicit and on the conceptual priming tasks. On these tasks the CHI group was expected to benefit to a lesser degree from prior deep encoding, as compared to controls. The groups were not expected to significantly differ from each other on the perceptual priming task. Prior deep encoding was not expected to improve the perceptual priming performance of either group. All findings were as predicted, with the exception that a significant effect was not found between groups for deep encoding in the conceptual priming task. The results are discussed (1) in terms of their theoretical contribution in further validating the dissociation between perceptual and conceptual priming; and (2) in terms of the contribution in differentiating between amnesic and CHI patients. Conceptual priming is preserved in amnesics but not in CHI patients.

Effects of parents' and pediatricians' worry concerning severe gastroenteritis in early childhood on later disturbances in the child's behavior.

Probands who had been hospitalized for gastroenteritis between the ages of 2 and 5 years were studied at the ages of 8 to 12 years. More conduct problems and a tendency to excessive dependence were found (1) in probands who were severely ill by objective criteria than were others and (2) in probands whose parents were specifically worried that their child might die as a result of the illness. General worry in the parents had different consequences. Other data suggest that pediatricians, because they are no longer worried about the illness after the child is discharged, may be failing to take appropriate preventative measures at opportune moments in the years following the hospitalization.
