In this study, we examined the musical compositions of children aged 7 and 9 years to discover the nature of childrens melodic and rhythmic representations of music. The compositions were performed using a computer program that did not require formal music training. Post hoc analysis revealed that the compositions could be divided into three melodic and rhythmic developmental stages that varied according to melodic contour, tonality, rhythmic grouping, and meter. Older children created more compositions at higher stages of complexity, and the more private musical training children had received, the more rhythmically complex their compositions were. The girls produced a greater percentage of compositions assigned to the highest stages than did the boys. Qualitative features of the subjects' approach to the task were noted during testing and were also found to vary with developmental stage. The number of parts inherent in the compositions was a nonpredictive variable in this analysis.

We discuss two issues raised in the article about the acquisition of absolute pitch published in Music Perception by W. A. Brown, H. Sachs, K. Cammuso, and S. E. Folstein (2002) with which we disagree. First, we describe that aspect of musical training we feel is relevant for the acquisition of absolute pitch. Second, we point out a disagreement about the statistical nature of developmental stages and critical periods. We describe an alternative view of absolute pitch acquisition.

Abstract University students were screened using items from the Psychopathic Personality Inventory and divided into high (n = 13) and low (n = 11) Psychopathic Personality Trait (PPT) groups. The P300 component of the event-related potential (ERP) was recorded as each group completed a two-block autobiographical oddball task, responding honestly during the first (Phone) block, in which oddball items were participants' home phone numbers, and then feigning amnesia in response to approximately 50% of items in the second (Birthday) block in which oddball items were participants' birthdates. Bootstrapping of peak-to-peak amplitudes correctly identified 100% of low PPT and 92% of high PPT participants as having intact recognition. Both groups demonstrated malingering-related P300 amplitude reduction. For the first time, P300 amplitude and topography differences were observed between honest and deceptive responses to Birthday items. No main between-group P300 effects resulted. Post-hoc analysis revealed between-group differences in a frontally located post-P300 component. Honest responses were associated with late frontal amplitudes larger than deceptive responses at frontal sites in the low PPT group only.
