Abstract
Keeping pace with an auditory click presented 1 per sec. and accelerated at a rate of .2 per sec. per 8 clicks, 16 Ss reproduced binary sequences, by pressing 2 telegraph keys. Mean maximum rates of response varied 3.32-5.61 per sec. The explanation of the order of difficulty holds that runs of the same element and single alternations constitute response units (RUs). Response rate is influenced by the number of junctures of RUs in a sequence: those with longer runs are easier and have few junctures. At a more analytic level, longer sequences are strings of RUs drawn from the 4 different 2-element or the 8 different 3-element sets. Mixtures of 2- and 3-element RUs increase the difficulty. Where the number of junctures in a sequence is the same, the sequence having repetitions of the same RU is easier. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
