“…One line of work (e.g., Brady & Oliva, 2008;Kidd, Piantadosi, & Aslin, 2012;Turk-Browne et al, 2005), studied adaptation to the regularity formed by their order (e.g., stimulus 'B' always follows stimulus 'A') and not by interval duration (e.g., 'B' reappears after a predictable interval, yet can be followed by either 'A' or 'C'). Other studies have shown that regular intervals can be implicitly learned: infants (Lewkowicz, 2003) and adults van Rijn, 2017, Olson andChun, 2001, Experiment 1a and b) can implicitly detect rhythmic interval patterns; temporal regularities influence the learning of language (Hay & Saffran, 2012) and artificial pitch grammar (Selchenkova, Jones, & Tillmann, 2014); temporal structure in a rapid serial visual presentation task can bias the probability of shifting the focus of attention (Sali, Anderson, & Yantis, 2015); and temporal information can be integrated in the learning of rhythmic perceptual-motor action sequences (Gobel, Sanchez, & Reber, 2011;O'Reilly, McCarthy, Capizzi, & Nobre, 2008;Schultz, Stevens, Keller, & Tillmann, 2013;Shin & Ivry, 2002). However, it is unclear whether implicit knowledge about regular IMPLICIT LEARNING OF TEMPORAL BEHAVIOR 5 intervals is used to anticipate when to act.…”
