Performance on two auditory choice reaction time (RT) tasks was studied in a group of 12 subjects under the influence of graded doses of ethyl alcohol ranging from placebo to 1 g/kg body weight. Deadline procedures were employed in a side discrimination and a pitch discrimination task to permit the calculation of speed-accuracy tradeoff functions (accuracy versus RT). Accuracy declined as a function of dose, but alcohol did not significantly influence RT. Conversely, accuracy was not affected by task; but the pitch discrimination task required an average of 88 ms more time than the side task. Alcohol dose and task produced independent effects on the speed-accuracy tradeoff function. As dose increased, the slope of the tradeoff function declined; but slopes were equivalent for the two tasks. On the other hand, the x-intercept (where accuracy equals chance levels) was 90 ms greater for the pitch task than for the side task.

The present study investigated the ERP correlates of the influence of tonal expectations on pitch processing. Participants performed a pitch discrimination task between penultimate and final tones of melodies. These last two tones were a repetition of the same musical note, but penultimate tones were always in tune whereas final tones were slightly out of tune in half of the trials. The pitch discrimination task allowed us to investigate the influence of tonal expectations in attentive listening and, for penultimate tones, without being confounded by decisional processes (occurring on final tones). Tonal expectations were manipulated by a tone change in the first half of the melodies that changed their tonality, hence changing the tonal expectedness of penultimate and final tones without modifying them acoustically. Manipulating tonal expectations with minimal acoustic changes allowed us to focus on the cognitive expectations based on listeners' knowledge of tonal structures. For penultimate tones, tonal expectations modulated processing within the first 100 msec after onset resulting in an Nb/P1 complex that differed in amplitude between tonally related and less related conditions. For final tones, out-of-tune tones elicited an N2/P3 complex and, on in-tune tones only, tonal manipulation elicited an ERAN/RATN-like negativity overlapping with the N2. Our results suggest that cognitive tonal expectations can influence pitch perception at several steps of processing, starting with early attentional selection of pitch.

Spatial Interference

Interference in serial spatial memory was investigated in six experiments. Experiment 1 replicated Experiment 2 by Smyth and Scholey (1994) in showing that listening to tones that originated from different directions interfered with spatial memory. Experiment 2 showed, however, that the effect of mere listening was not observed when this was the only interference condition experienced by the subject. In Experiment 3, a binary pitch discrimination task performed on spatially separated tones impaired recall performance to the same extent as did left-right decisions. The same disrupting effect was also observed when the tones were presented from the same direction in the pitch discrimination task (Experiment 4) as well as in a binary loudness discrimination task (Experiment 5). Finally, repeating heard words did not interfere, whereas a pitch discrimination performed on these same words disrupted recall (Experiment 6). It is argued that the disrupting effects reflect not a specifically spatial interference, but a central executive involvement in the rehearsal process in serial spatial memory.

Discrimination Ability

Purpose The Pitch Patterns Test (PPT) and the Duration Patterns Test (DPT) are clinical auditory processing tests that evaluate temporal patterning skills based on pitch (PPT) or duration (DPT) aspects of sound. Although temporal patterning tests are categorized under the temporal processing domain, successful performance on the PPT also relies on accurate pitch discrimination. However, the relationship between pitch discrimination ability and temporal patterning skills has not been thoroughly evaluated. This study examined the contribution of pitch discrimination ability to performance on temporal patterning in children through the use of a pitch discrimination task and the PPT. The DPT was also given as a control measure to assess temporal patterning with no pitch component. Method Thirty-two typically developing elementary school–age children (6;11–11;3 [years;months]) with normal hearing were given a series of three counterbalanced tasks: an adaptive psychophysical pitch discrimination task (difference limen for frequency [DLF]), the PPT, and the DPT. Results Correlational analysis revealed moderate correlations between DLF and PPT scores. After accounting for age, results of a linear regression analysis suggested that pitch discrimination accounts for a significant amount of variance in performance on the PPT. No significant correlation was found between DLF and DPT scores, supporting the hypothesis that the pitch task had no significant temporal patterning component contributing to the overall score. Discussion These findings indicate that pitch discrimination contributes significantly to performance on the PPT, but not the DPT, in a typically developing pediatric population. This is an important clinical consideration in both assessment and utilization of targeted therapy techniques for different clinical populations.
