Comparisons between familiar/unfamiliar pairs and between sight-allowed/isolated pairs for the recorded variables during the test (Phase 3).

Comparisons between familiar (FA, n = 12) and unfamiliar (UN, n = 12) pairs and between sight-allowed (SP, n = 12) and isolated pairs (IP, n = 12) for the recorded variables after a two-way measured MANOVA followed by univariate tests for between-subjects effects (statistic: F; factors: sight-allowed/isolated pairs and familiar/unfamiliar pairs). Significant differences are denoted in bold.
