Examples of grammatical exposure sequences
Example of test sequences
Schematic presentation of an experimental trial
(visual information (left), tone sequence
(right) presented on a time line)
The fixation cross preceded the sequence, then
each visual cue was synchronized to the onset of
a tone. In the present example, the to-be-judged
target is in the fifth position. Visual
information was presented in the center of the
computer screen. Tone sequences were presented
auditorily over headphones.
Note Grammatical and ungrammatical sequences
differed by a single tone. This tone was part of
the set of tones used in the grammatical
sequences and over the entire set, ungrammatical
sequences did not differ from grammatical
sequences in terms of frequency distributions of
tones, bigrams and melodic contour features.
