The aim of these two studies was to examine the application of Lang’s (1979, 1985) bioinformational theory to the mental practice (MP) of a strength task, the maximal voluntary contraction of the abductor digiti minimi, and the MP of a computerized barrier knockdown task. Study 1 divided 18 males into three groups: a physical practice (PP) group; a stimulus and response proposition mental practice (SRP) group; and a stimulus proposition mental practice (SP) group. Each participant either physically or mentally practiced 40 contractions twice a week for 3 weeks, and electroencephalograms (EEGs) were recorded during testing sessions. All three groups significantly increased abduction strength, but there were no significant between-group differences in the magnitude of the improvements. In addition, late contingent negative variation (CNV) waves were apparent prior to both real and imagined movements in all conditions. Study 2 allocated 24 participants to PP, SRP, SP, and control groups. Participants performed 120 imaginary or actual barrier knockdown trials, with EEGs recorded as in Study 1. A Group × Test ANOVA for movement time revealed that the PP and SRP groups improved to a significantly greater degree than the SP and control groups. Also, the late CNV was observed prior to real and imagined movement in the SRP group, but not prior to imagined movement in the SP group. These results support bioinformational theory with respect to cognitively oriented motor tasks, but not strength tasks.
