The 11th Perceptual Frontier Seminar

Date and time: 22 January 2014, 18:00-20:00
Venue: Room 601, 6 F, Build. 3, Ohashi Campus, Kyushu University
Talkers: Miharu FUYUNO, Emi HASUO, and Takako MITSUDO

1. Cognitive linguistics meets corpora: Examples of human spatial cognition reflected in English language
Miharu FUYUNO*
This talk will discuss several examples from cognitive linguistic studies such as English spatial prepositions and constructions, after providing introductory descriptions of cognitive linguistics and corpus linguistics. Cognitive Linguistics has been developing as a descriptive framework for linguistic investigations with its central principal of analyzing languages as reflections of human cognitive abilities. In this talk, reflections of human spatial cognitions in uses of English prepositions (on, in, at) and related issues will be discussed as well as increasing applications of corpora in cognitive linguistic studies.

2. Perceived durations of filled and empty intervals measured with magnitude estimation

Three-sentence abstract: The purpose of this study was to examine whether the relationship between the perceived durations of a filled interval (the duration between the onset and the offset of a sustained sound) and an empty interval (the duration between the onsets of two successive brief sounds) differed for shorter and longer intervals. Subjective durations of filled and empty time intervals of 30, 49, 81, 134, 221, 364, and 600 ms were measured from 41 participants using magnitude estimation. Results showed that the subjective durations of filled intervals increased linearly as the duration lengthened, whereas those of empty intervals increased with a steeper slope for durations up to 134 ms than for longer durations (Data of a related experiment with electroencephalography may also be presented).

3. Perceptual inequality between two neighbouring time intervals defined by sound markers: correspondence between neurophysiological and psychological data

*Kyushu University, **RIKEN
A slow negative component (SNCt) in the right pre-frontal brain area [around the F8 electrode in electroencephalographic (EEG) observations] after stimulus, which was found to be associated with judgment of the equality/inequality of two neighbouring time intervals (T1 and T2) in one of our previous studies, was further investigated.  The SNCt appeared in the right-frontal area after the presentation of T1 and T2, and its magnitude was larger for the temporal patterns causing perceptual inequality; it was also correlated with perceptual equality/inequality of the same stimulus pattern. The SNCt turned out to continue up to about 400 ms after the end of T2, and was established as a signature of equality/inequality judgment as well as of inequality detection.
