Listeners regularly judge the accuracy of musical performances. However, as is true for several types of judgments (e.g., beauty or obscenity), estimating the correctness of melodies is not based on a precise definition of the object/performance but rather follows arguments such as “I know it when I hear it”. In order to clarify the definition of correctness in melodies, participants identified parametrically manipulated sung melodies as in-tune or out-of-tune, using the method of limits procedure (Experiment 1). Listeners’ tolerance with regard to mistuning was compared across melodies (Experiment 2). The potential roots of correctness perception were investigated by testing the effect of familiarity, the influence of formal musical training (Experiment 3), and the task repetition effect (Experiment 4). The results highlight a surprisingly small tolerance with regard to mistuning (half of a quarter tone), whatever the melodic context, large individual differences, but high consistency over time. This high sensitivity was mainly modulated by musical training as well as by previous exposure. In addition to defining the boundary between in- and out-of-tune melodies, this study supports the implicit development of the normative notion of “correctness” as a category that might drive listeners’ appreciation of artistic performances.

SUMMARY:Two approaches to the study of the kindling phenomenon were discussed: 1) an attempt to identify the pattern of neural activity required to produce the changes underlying kindling and 2) an investigation into the nature of those changes. Three experiments were reported that used the neocortical transcallosal system as a monosynaptic model system in which to study possible synaptic mechanisms of the kindling effect. Experiment I showed an increase in the transcallosal evoked potential following neocortical kindling. Experiment II showed an increase in the strength of the transcallosal evoked cell discharge following neocortical kindling. Experiment III reported the results of an histological examination of neocortical tissue in kindled and non-kindled animals using the Golgi-Cox technique. Spine density, spine dimension and branching were measured for pyramidal cell apical dendrites. No differences were found between primary and secondary (contralateral) foci or between kindled and non-kindled animals.

Effect Experiment

Research on perceptual learning shows that the way stimuli are presented leads to different outcomes. The intermixed/blocked (I/B) effect is one of these outcomes, and different mechanisms have been proposed to explain it. In human research, it seems that comparison between stimuli is important, and the placement of a distractor between the pre-exposed stimuli interferes with the effect. Results from animal research are usually interpreted in different terms because the type of procedure normally used in animal perceptual learning does not favour comparison. In our experiments, we explore the possibility that a distractor placed between the to-be-discriminated stimuli may interfere with the perceptual learning process in rats. In Experiment 1, two flavoured solutions are presented in an I/B fashion, with a short time lapse between them to favour comparison, showing the typical I/B effect. In Experiment 2, we introduced a distractor in between the solutions, abolishing this effect. Experiment 3 further replicates this by comparing two intermixed groups with or without distractor. The results replicate the findings from human research, suggesting that comparison also plays an important role in animal perceptual learning.
