Abstract

The relationship of Witkin's dimension of field-dependence to the ability voluntarily to enhance the EEG alpha rhythm was investigated. Field-dependence was assessed by latencies on the Embedded-figures Test. To replicate the finding that feedback of one's alpha rhythm leads to self-regulation of its production, 21 male undergraduates were randomly divided into 2 groups, one receiving alpha biofeedback training for 1 hr., the other group resting under similar conditions but given different instructions and no feedback. Ss in the feedback group were given the embedded-figures 1 wk. prior to training. After training, Ss demonstrated more alpha than controls (p < .05), with percentage alpha produced being negatively related to EFT latencies (p < .05). Data show ability to differentiate environmental cues generalized to internal cues.
