To determine whether different long-term memory representations are necessary for verbal and visual material, subjects studied faces composed of visual features or verbal facts composed of concepts. Findings showed interference between verbal and pictorial information, and supported the ACT theory that pictorial and verbal materials are stored…

The hypothesis that reading difficulty of learning disabled (LD) children is attributable to deficiencies in verbal encoding was investigated with 60 LD and normal children (mean CA=9.1, mean IQ=103.5). Ss were compared on recall of a serial short-term memory task after pre-training of named and unnamed stimulus conditions. Data suggested that…

Rich visual stimuli provided by the television medium may affect youngsters' cognitive processes and strategies in academic performance. Previous studies have revealed that television viewing enhances their achievement test scores through grade four, but scores decline after grade four.

Seven studies were conducted to investigate the interactions between imagery-ability and experimental treatments that parallel instructional procedures. The general orientation of the studies was to extend the concepts of imaginal and verbal coding systems to include individual differences in symbolic habits. Thus all the studies took into account…

Three experiments tested whether qualitative differences in processing of verbal materials result from congenital hearing impairment. Subjects were children with reading levels equivalent to grades 4 to 6. Experiment 1 used repeated measurements with two modes of response and two kinds of cues; experiment 2 used acoustic similarity to produce…
