“…Replication and extension of key findings in the literature will be critical for the development of the field (Pavlov et al, 2021), and the replication studies included in this Special Issue provide valuable examples. It is of course crucial that methodologies should be optimised for replication attempts (Fiebelkorn, 2021; ten Oever et al, 2022). However, if seminal studies are considered to have methodological flaws (such as low statistical power), then it is all the more important that the results are validated through replications.…”

“…In a commentary on Van der Werf et al's study, Fiebelkorn (2021, this issue) proposes that, despite being comparable to the original study (Helfrich et al, 2018), the number of trials per condition employed in the replication may have been too low to reliably detect attentional rhythms. Fiebelkorn further suggests that using purely behavioural data to detect rhythms in cognition might be limiting and suggests that combining behavioural data with simultaneously recorded electrophysiology might be more appropriate (but see ten Oever et al, 2022, this issue, for a response to Fiebelkorn's commentary).…”

“…We suggest that our data increase insight into the conditions in which periodic rhythms can provide perceptual advantages to targets embedded in these rhythms. The hypothesized explanatory mechanisms, in which we suggest interactions between oscillatory entrainment and top-down attentional effects should be tested by neurophysiological or electrophysiological experiments [47]. In the no-instruction condition, participants received no instruction on possible target positions within the temporal sequences and remained unaware that targets occurred always at the same position.…”

Predictability awareness rather than mere predictability enhances the perceptual benefits for targets in auditory rhythms over targets following temporal cues

Sounds following a cue or embedded in a periodic rhythm are processed more effectively than sounds that are part of an aperiodic rhythm. One might also expect that a sound embedded in a periodic rhythm is processed more effectively than a sound following a single temporal cue. Such a finding would follow the theory that the entrainment of neural rhythmic activity by periodic stimuli renders the prediction of upcoming stimuli more efficient. We conducted a psychophysical experiment in which we tested the behavioral elements of this idea. Targets in periodic and aperiodic rhythms, if they occurred, always appeared at the same moment in time, and thus were fully predictable. In a first condition, participants remained unaware of this. In a second condition, an explicit instruction on the temporal location of the targets embedded in rhythms was provided. We assessed sensitivity and reaction times to the target stimuli in a difficult temporal detection task, and contrasted performance in this task to that obtained for targets temporally cued by a single preceding cue. Irrespective of explicit information about target predictability, target detection performance was always better in the periodic and temporal cue conditions, compared to the aperiodic condition. However, we found that the mere predictability of an acoustic target within a periodic rhythm did not allow participants to detect the target any better than in a condition where the target’s timing was predicted by a single temporal cue. Only when participants were made aware of the specific moment in the periodic rhythm where the target could occur, did sensitivity increase. This finding suggests that a periodic rhythm is not automatically sufficient to provide perceptual benefits compared to a condition predictable yet not rhythmic condition (a cue). In some conditions, as shown here, these benefits may only occur in interaction with other factors such as explicit instruction and directed attention.
