Table 3.

Main effects and interactions of context-sensitive factors from the three-factor ANOVA

Trial phase effects	Number of units (percentage of total)^b	Number of units excluding bisected fields (percentage of total)^c	Turn direction effects	Number of units	Number of units excluding bisected fields
Trial phase	38 (49.4)	20 (45.5)	Turn direction	3 (3.9)^a	2 (4.5)
Trial phase × turn direction	11 (14.3)	6 (13.6)	Trial phase × turn direction	11 (14.3)	6 (13.6)
Trial phase × stem segment	5 (6.5)	2 (4.5)	Turn direction × stem segment	0 (0)	0 (0)

↵^aThese units showed a main effect of both trial phase and turn direction.
↵^bThis analysis was performed on 77 units.
↵^cThis analysis was performed on 44 units (excluding clusters whose field center was located in the delay zone).
