Abstract
Recent research has demonstrated that television‐as‐background can interfere with performance on several types of difficult cognitive processing tasks. Armstrong and Greenberg (1990) argue that these effects are most likely the result of competition between TV and a primary task for central processing resources (capacity interference). An alternative hypothesis is that observed effects result from competition for more specific types of processing resources, rather than general capacity limits. It was hypothesized that background television would produce structural interference specifically with semantic memory and visuo‐spatial processing tasks. Controlling for prior abilities as assessed by pretests using parallel test forms, background television had a significant deleterious effect on a geometric analogies and completions task involving visuo‐spatial processing, while performance on a parallel verbal analogies test was marginally improved. Concurrent TV exposure had no influence on a test of semantic m...
