Abstract
To examine the relation between rate of presentation and information-dumping effect with more detailed pictures, two experiments were performed using a list of 17 living things and 17 nonliving things to be recalled. In Exp. I, 18 university students were instructed to pay particular attention to the living-thing items, while the remaining 18 were asked to pay attention to all the items in the list. The results showed that the information-dumping effect was obtained and the effect occurred strikingly irrespective of rate of presentation (0.3 sec. vs 0.6 sec.). Also, the use of more detailed pictures as stimulus material inhibited the over-all recall. Exp. II replicated Exp. I with response productivity held constant. The results also showed that the same outcomes as in Exp. I were obtained when response productivity was held constant.
