Three experiments studied the perception of tone sequences having various degrees of musical structure. Ratings of perceived structure and ease of recognition in transposition were both influenced by harmonic progression (as defined by music theory), the contour (directional changes in pitch), and the excursion or repetition pattern within the sequence.

Thirty-six different binaural noises were formed by crossing six right-ear intensities of a broadband noise with the same six intensities in the left ear in a 6 X 6 factorial design. Children (6-7 years of age) and adults were presented with 2 of these 36 binaural noises on a trial and asked to indicate which noise was louder. In Experiment 1, the left- and(More)
Over the past 60 years, the federal government has provided funding for child care and early education programs in fits and starts.

C57BL/6J and C57BL/6J-rd le Gus-sh mice, congenics at the rd locus, were compared with respect to number of granule cells and presumed pyramidal basket cells in the hippocampal dentate gyrus. Number of both types of neurons were less in rd/rd mice than in +/-/+/- mice. The rd gene may be responsible.
The psychological relevance of the musicians' concept of tonality was tested in the context of the music of J. S. Bach. Musically trained listeners were instructed to sing the musical scale that first came to mind immediately after hearing short excerpts from Preludes of J. S. Bach's The Well-Tempered Clavier. For each Prelude, the tonic (first note) and(More)
