Many interactive human skills are based on real-time error detection and correction. Here we investigate the spectral properties of such skills, focusing on a synchronization task. A simple autoregressive error correction model, based on separate 'motor' and 'cognitive' sources, provides an excellent fit to experimental spectral data. The model can also(More)
We present a tutorial on a power spectral approach to variability in serial motor performance, describing as a case study two experiments on the form of the variance in two force production tasks. In Experiment 1 we examine grip force and load force in repetitive unimanual pulling; in Experiment 2, we describe repetitive bimanual pressing. In both(More)
2 0. ABSTRACT Previous studies have suggested that the cerebellum and basal ganglia may play a critical role in interval timing. In the first part of the chapter, we review this literature, focusing on production and perception tasks involving intervals in the hundreds of millisecond range. Overall, the neuropsychological and neuroimaging evidence(More)
In 3 experiments, the authors examined short-term memory for pitch and duration in unfamiliar tone sequences. Participants were presented a target sequence consisting of 2 tones (Experiment 1) or 7 tones (Experiments 2 and 3) and then a probe tone. Participants indicated whether the probe tone matched 1 of the target tones in both pitch and duration. Error(More)
Free jazz refers to a historical movement that, despite earlier precedents, first significantly flowered in the late 1950s in the US. Its central focus was a liberation from musical conventions – but from a jazz player's perspective, since no liberation is ever complete. Initially known simply as the New Thing, it became Free Jazz by borrowing the title of(More)
