Further Evidence That the Effects of Repetition on Subjective Time Depend on Repetition Probability
نویسندگان
چکیده
Repeated stimuli typically have shorter apparent duration than novel stimuli. Most explanations for this effect have attributed it to the repeated stimuli being more expected or predictable than the novel items, but an emerging body of work suggests that repetition and expectation exert distinct effects on time perception. The present experiment replicated a recent study in which the probability of repetition was varied between blocks of trials. As in the previous work, the repetition effect was smaller when repeats were common (and therefore more expected) than when they were rare. These results add to growing evidence that, contrary to traditional accounts, expectation increases apparent duration whereas repetition compresses subjective time, perhaps via a low-level process like adaptation. These opposing processes can be seen as instances of a more general "processing principle," according to which subjective time is a function of the perceptual strength of the stimulus representation, and therefore depends on a confluence of "bottom-up" and "top-down" variables.

This quasi-experimental study aimed to investigate the effect of task repetition under four conditions on the three dimensions of oral production (accuracy, complexity and fluency) and grammatical knowledge gain of learners of English as a Foreign Language (EFL). 40 young learners of English as a Foreign Language in four classes were randomly assigned into one of the following groups: repetitio...

It has been suggested that repeated stimuli have shorter subjective duration than novel items, perhaps because of a reduction in the neural response to repeated presentations of the same object. Five experiments investigated the effects of repetition on time perception and found further evidence that immediate repetition reduces apparent duration, consistent with the idea that subjective durati...

Task repetition is now considered as an important task-based implementation variable which can affect complexity, accuracy, and fluency of L2 speech. However, in order to move towards theorizing the role of task repetition in second language acquisition, it is necessary that individual variables be taken into account. The present study aimed to investigate the way task r...
متن کاملTime perception: the surprising effects of surprising stimuli.
The effects of stimulus repetition often increase when repetitions are more common (i.e., when repeats become more predictable), consistent with the idea that repetition effects reflect expectations about the recurrence of recent items. In contrast, the present experiments found a surprising pattern in which the compressed subjective duration of repeated items was reduced, eliminated, and even ...
متن کاملNeuroimaging evidence for dissociable forms of repetition priming.
Repetition priming has been characterized neurophysiologically as a decreased response following stimulus repetition. The present study used event-related functional magnetic resonance imaging to investigate whether this repetition-related response is sensitive to stimulus familiarity. A right fusiform region exhibited an attenuated response to the repetition of familiar stimuli, both faces and...
