Perception Of Mode, Rhythm, And Contour In Unfamiliar Melodies: Effects Of Age And Experience, Andrea R. Halpern, James C. Bartlett, W. Jay Dowling Jan 1998

Perception Of Mode, Rhythm, And Contour In Unfamiliar Melodies: Effects Of Age And Experience, Andrea R. Halpern, James C. Bartlett, W. Jay Dowling

Faculty Journal Articles

We explored the ability of older (60-80 years old) and younger (18-23 years old) musicians and nonmusicians to judge the similarity of transposed melodies varying on rhythm, mode, and/or contour (Experiment 1) and to discriminate among melodies differing only in rhythm, mode, or contour (Experiment 2). Similarity ratings did not vary greatly among groups, with tunes differing only by mode being rated as most similar. In the same/different discrimination task, musicians performed better than nonmusicians, but we found no age differences. We also found that discrimination of major from minor tunes was difficult for everyone, even for musicians. Mode is …


Recognition Of Familiar And Unfamiliar Melodies In Normal Aging And Alzheimers-Disease, James C. Bartlett, Andrea R. Halpern, W. Jay Dowling Jan 1995

Recognition Of Familiar And Unfamiliar Melodies In Normal Aging And Alzheimers-Disease, James C. Bartlett, Andrea R. Halpern, W. Jay Dowling

Faculty Journal Articles

We tested normal young and elderly adults and elderly Alzheimer's disease (AD) patients on recognition memory for tunes. In Experiment 1, AD patients and age-matched controls received a study list and an old/new recognition test of highly familiar, traditional tunes, followed by a study list and test of novel tunes. The controls performed better than did the AD patients. The controls showed the ''mirror effect'' of increased hits and reduced false alarms for traditional versus novel tunes, whereas the patients false-alarmed as often to traditional tunes as to novel tunes. Experiment 2 compared young adults and healthy elderly persons using …


Memory Biases In Left Versus Right Implied Motion, Andrea R. Halpern, Michael H. Kelly Jan 1993

Memory Biases In Left Versus Right Implied Motion, Andrea R. Halpern, Michael H. Kelly

Faculty Journal Articles

People remember moving objects as having moved farther along in their path of motion than is actually the case; this is known as representational momentum (RM). Some authors have argued that RM is an internalization of environmental properties such as physical momentum and gravity. Five experiments demonstrated that a similar memory bias could not have been learned from the environment. For right-handed Ss, objects apparently moving to the right engendered a larger memory bias in the direction of motion than did those moving to the left. This effect, clearly not derived from real-world lateral asymmetries, was relatively insensitive to changes …


Mental Scanning In Auditory Imagery For Songs, Andrea R. Halpern Jan 1988

Mental Scanning In Auditory Imagery For Songs, Andrea R. Halpern

Faculty Journal Articles

Four experiments examined how people operate on memory representations of familiar songs. The tasks were similar to those used in studies of visual imagery. In one task, subjects saw a one-word lyric from a song and then saw a second lyric; then they had to say if the second lyric was from the same song as the first. In a second task, subjects mentally compared pitches of notes corresponding to song lyrics. In both tasks, reaction time increased as a function of the distance in beats between the two lyrics in the actual song, and in some conditions reaction time …


Perception Of Structure In Novel Music, Andrea R. Halpern Jan 1984

Perception Of Structure In Novel Music, Andrea R. Halpern

Faculty Journal Articles

Two experiments demonstrated the way in which musicians and nonmusicians process realistic music encountered for the first time. A set of tunes whose members were related to each other by a number of specific musical relationships was constructed. In experiment I, subjects gave similarity judgments of all pairs of tunes, which were analyzed by the ADD-TREE clustering program. Musicians and nonmusicians gave essentially equivalent results: Tunes with different rhythms were rated as being very dissimilar, whereas tunes identical except for being in a major versus a minor mode were rated as being highly similar. In Experiment 2, subjects learned to …
