This research explored the biological autonomy and control of function according to their circumstances that the purported relationship to the environmental cycle. For understanding this directed behavior as a call for the organism-environment system rather than simply the organism, the present study sought to expose the laws that underlie intelligent capabilities measuring biological characteristic (internal source) in circadian temperature (external source) context.
Participants (n = 32) at the University of Connecticut (Storrs, USA) and the Seoul National University (Seoul, Korea) served in the study. For inspecting the internal features (motor synchrony) depending on external context (environmental cycles), relative phase of two handheld pendulums was obtained along four different circadian points, thus day-night temperature effects were compared. Specifically, the in-phase of bi-manual coordination was observed in two experimental design: one design is normal circadian process [temperature embedded in 24 hours light-dark cycles (5:00, 12:00, 17:00, and 24:00)], the other design is normal [temperature embedded in light-dark cycles (5:00 am, 5:00 pm)] verses abnormal [artificially decreasing or increasing temperature (5:00 am, 5:00 pm)] circadian process.
The experimental model with a typical bi-manual stability measure shows that the dependent variable significantly vary in accordance to day-night temperature cycle. While (i) circadian effect under the artificially perturbed temperature manipulation seems not constant to be along the day-night temperature cycle, (ii) circadian effect divided by the ordinary circadian seems to be constant along the day-night temperature cycle.
The discovery of direct and robust relation between the biological aspects (body temperature and motor synchrony) over a broad range of environmental process, might mirror the unique adaptation of our biological system to the environment. Thus, the organism (X) and the environment (Y) should be considered as integrated system (hence, X-Y system) in which biological (or physical) dynamics takes place as a mutual factor.
