Abstract

The interaction between the arousal to action of environmental stimuli and recovery from that activity was presumed to generate biorhythms in the activity level of children. The level of environmental stimuli was manipulated by varying the play-group size and the apparatus, and higher environmental complexity was expected to produce more pronounced rhythms. The heart rates of 16 subjects playing in monad, dyad, and tetrad group sizes, in two playroom configurations, were monitored and spectral analysis used to locate significant biorhythms. There was a tendency toward 40-min (slow frequency) and 15-min (fast frequency) biorhythms. The group size manipulation produced the strongest biorhythmic behavior in the dyadic groups. Apparatus differences were not significant but the configuration containing a minimum quantity of play apparatus produced more variable activity than the configuration containing a large amount of play apparatus.
