Effects of Different Variables on Information Processing

The objective of this study was to assess the effects of different variables on the efficiency of information processing. Two experiments were performed in this study in the pursuit of this objective. In one of the experiments, the effect on the efficiency of target symbol identification was measured within the context of similar and dissimilar symbol placement. The effect was based on the placing the target symbol among similar symbols, as opposed to placing the target symbol among dissimilar symbols. In the second experiment, the effect on the efficiency of target symbol identification was measured within the context of random and structured placement. The effect was based on the placing the target symbol within a random group of symbols, as opposed to placing the target symbol within a structured group of symbols.

The findings of Experiment 1 confirmed the findings reported in the literature that the placing of target symbols within backgrounds of dissimilar symbols causes the process of target symbol identification to be more efficient that it is when target symbols are placed within backgrounds of similar symbols. The findings of Experiment 2 contrasted with the findings reported in the literature that the placing of target symbols within random backgrounds of symbols causes the process of target symbol identification to be more efficient that it is when target symbols are placed within structured backgrounds of symbols. Thus, the findings of this study

irmed by Lippman (1978, pp. 697706), who found that total list learning was facilitated when the isolate was placed at the seventh position in a 12item consonantvowelconsonant (CVC) list. A subsequent study confirmed the greater isolation effect attained through the location of isolated items at the center positions of a list (Huang and Wille, 1979, pp. 2734). This study, however, failed to confirm the findings of a positive isolation effect on total list learning. In the context of the impact of the serial position of the isolate on learning, it is worthwhile to consider the findings of Miller (1956, pp. 8197). Miller (1956, pp. 8197) found that most humans acquire information in bits, through a process known as "chunking." Chunking means that an individual acquires groups of data at one time (Miller, 1956, pp. 8197). Miller (1956, pp. 8197) found that the typical human can acquire approximately seven items of data at one time (plus or minus two). It is interesting to note that the studies which found that centrallist serial positions increased the isolation effect on learning, where all studies which relied on relatively small lists, in which the central position would be at or within two plac
