Effects of accenting and regularity on the detection of temporal deviations: Does regularity facilitate performance?

Tekman, HG
In an experiment on the effect of intensity accents on the perception of time intervals between tones, H. G. Tekman (2001) found that the regular placement of deviant time intervals in short sequences of tones reduced detection, especially if intensity accents marked the deviant time intervals. That was the opposite of what one would have expected on the basis of the dynamic attending theory of M. R. Jones (1976). The effect might have occurred because temporally deviant tones create cumulative onset shifts that affect all the subsequent tones. If the deviations were randomly placed, then they could follow each other in close succession and change the local tempo. In the present study, the changes of local tempo, which might have acted as a cue for the detection of temporal deviations in the random sequences, were eliminated by compensating for deviant time intervals with equal deviations in the opposite direction in the interval that followed. That change in the stimuli eliminated the negative main effect of regularity, and the accenting interacted with regularity in favor of detection in the regular sequences. However, a simple advantage of regular over random sequences was not observed. The author discusses possible reasons for the lack of a facilitatory effect of regularity.


Accenting and detection of timing variations in tone sequences: Different kinds of accents have different effects
Tekman, HG (Springer Science and Business Media LLC, 2001-04-01)
The effect of intensity and pitch accents on the perception of timing was examined in two experiments using a signal detection procedure. Analyses of sensitivity and response bias revealed opposite effects of intensity and pitch accents under similar conditions. Time intervals preceding intensity accents were perceived as longer, but time intervals preceding pitch accents were perceived as shorter. These results showed that listeners found it easier to detect timing variations that were contrary to expectat...
The relationship between auditory-visual speech perception and language-specific speech perception at the onset of reading instruction in English-speaking children
Erdener, Dogu; Burnham, Denis (Elsevier BV, 2013-10-01)
Speech perception is auditory visual, but relatively little is known about auditory visual compared with auditory-only speech perception. One avenue for further understanding is via developmental studies. In a recent study, Sekiyama and Burnham (2008) found that English speakers significantly increase their use of visual speech information between 6 and 8 years of age but that this development does not appear to be universal across languages. Here, the possible bases for this language-specific increase amon...
Effects of perceptual fluency on autobiographical memories
İnan, Aslı Bahar; Tekman, Hasan Gürkan; Department of Cognitive Sciences (2009)
The aim of this study was to find if manipulating fluency, that is, the ease of processing, could affect confidence ratings about whether an event occurred in the respondents’ past. To test the familiarity misattribution hypothesis, which states that familiarity caused by fluent processing can be misattributed to past experience if the source of fluency cannot be identified, two methods were used: a revelation task, which was anagram solving and repetition priming. In the revelation task the familiarity mis...
Is attention drawn to changes in familiar scenes?
Karacan, Hacer (Uke); Hayhoe, Mary M. (Informa UK Limited, 2008-01-01)
In this study, we examined the mechanisms that control attention in natural scenes. We asked whether familiarity with the environment makes subjects more sensitive to changes or novel events in the scene. Previous investigation of this issue has been based on viewing 2-D images of simple objects or of natural scenes, a situation that does not accurately reflect the challenges of natural vision. We found that familiarity with the environment significantly increased the time spent fixating regions in the scen...
Effects of inhibitory mechanisms and thought suppression tendency on the frequency and intensity of traumatic intrusions
Yarar, Orhan Ferhat; Gençöz, Faruk; Mısırlısoy, Mine; Department of Psychology (2011)
The present study investigates the effects of cognitive inhibitory mechanisms and tendency to suppress thoughts on the frequency and intensity of traumatic intrusions within the trauma film paradigm. Non clinical participants’ response inhibition and proactive inhibition levels and tendency to suppress thoughts were measured prior to exposure to a trauma film. One week after seeing the trauma film, participants reported the frequency and intensity of trauma film related intrusions with an intrusion diary an...
