Points out that advances in research include field experiments and panel studies permitting the use of nonexperimental causal-inference techniques. Notes that the scope of recent research has expanded to include cognitive processing of televised information and other types of effects (e.g., children's concepts of social reality). Suggests…

Four experiments investigated phonemic and visual similarity effects in 5- and 10-year olds. Results suggested that young children rely on modality-dependent codes, which are probably automatically activated, and do not use a speech-based memory code for drawings and words. This pattern of findings appeared to be independent of culture and…

Two studies on M-capacity found factor-analytical and correlational evidence that five M-capacity tests share a common source of variance and that, as subjects' increase in age, scores increase at a similar rate. Results suggest that, in the 6-11 age range, M-capacity can be measured with a battery of tests. (AA)
