Abstract
Fifty circular lights differing in diameter from 4 to 53 cm and increasing by 1 cm were presented 135 times each to five Ss who were asked to identify each circle. Presentations were in random order. Indices of information transmission (T), response equivocation HS(R), and response uncertainty H(R) were calculated for different phases of the experiment for individual and pooled (across Ss) responses. Results have shown systematic rising of transmission and lowering of HS(R), while H(R) remained almost constants. All transmission indices calculated from pooled responses were systematically lower than comparable indices calculated from individual responses.
