Noise and attention span.

The effect of emotional arousal, as induced by broad-band noise, upon breadth of attention was investigated. Four intensity levels were employed (no noise, 75 db, 85 db, and 100 db). Two of the tasks, Stroop color-word test, rod-and-frame test, required narrowed attention and the third, Tsai-Partington pathways test, required broader attention. Arousal level did not significantly affect performance on the rod-and-frame test or the pathways test, althouth in the latter a curvilinear trend was suggested. A complex relationship between arousal level and Stroop performance was obtained; performance of the 85-db group was superior to that of other groups, which did not differ significantly from one another. Results were discussed in terms of Easterbrook's (1959) arousal hypothesis.

Training in musical rhythm and field dependence of children.

The present experiment investigated the effects of musical rhythm training on field dependence in children. An experimental group of 12 Ss showed significant improvement on the Children's Embedded-figures Test and the Rod-and-frame Test after training, while a matched control group did not improve. Pretest scores on the children's Embedded-figures Test and the Rod-and-frame Test were not correlated.
