Point of subjective simultaneity and simple reaction time were compared for stimuli with different rise times. It was found that these measures behave differently. To explain the result it is suggested that in the case of temporal-order judgment the subject takes into account not only the stimulus onset but also other events connected with stimulus presentation.

AbstractThis study examines how variation in production is perceived and then (re)interpreted by listeners, thus providing the link between phonetic variation and sound change. We investigate whether listeners can detect the nasal leak that may accompany utterance-initial voiced stops in Spanish, and reinterpret it as a nasal segment. Such reinterpretation may account for a number of sound patterns involving emergent nasals adjacent to voiced stops in oral contexts. Oral pressure, nasal/oral airflow, and audio were recorded for utterance-initial /b d p t/ produced by 10 Spanish speakers. Tokens showing different degrees of nasal leak (nasal C, maximum, medium, and no nasal leak) were placed intervocalically, where both /C/ and /NC/ may occur. The stimuli were presented to Spanish listeners for identification as /VNCV/ or /V(C)CV/. Identification results indicate a higher number of VNCV responses with incremental changes in nasal leak in voiced but not voiceless stimuli. Reaction time analysis showed shorter latencies to nasal identification for larger velum leak stimuli. The results suggest that listeners can `hear' the nasal leak and fail to relate it to voicing initiation, interpreting a nasal segment. Thus a gesture aimed at facilitating voicing initiation may be interpreted as a new target goal.

To remove the influence of spuriously long response times, many investigators compute “restricted means”, obtained by throwing out any response time more than 2.0, 2.5, or 3.0 standard deviations from the overall sample average. Because reaction time distributions are skewed, however, the computation of restricted means introduces a bias: the restricted mean underestimates the true average of the population of response times. This problem may be very serious when investigators compare restricted means across conditions with different numbers of observations, because the bias increases with sample size. Simulations show that there is substantial differential bias when comparing conditions with fewer than 10 observations against conditions with more than 20. With strongly skewed distributions and a cutoff of 3.0 standard deviations, differential bias can influence comparisons of conditions with even more observations.
