The sound localization acuity of cats was determined at 0 degrees, 30 degrees, 60 degrees, and 90 degrees from the median sagittal plane for four durations of noise bursts using two behavioral procedures. Similar thresholds were also obtained for humans. The cats' average thresholds for a 40 ms noise burst ranged from 4.8 degrees at 0 degrees azimuth to 9.0 degrees at 90 degrees azimuth. Compar...

Four experiments explored possible roles for working memory in sound localization. In each experiment, the angular error of localization was assessed when performed alone, or concurrently with a working-memory task. The role of the phonological slave systems in auditory localization was ruled out by Experiments 1 and 2, while an engagement of central resources was suggested by the results of Ex...

W. Grey Walter built robotic systems to improve understanding of biological systems. In that tradition, this paper reports ongoing work on a robot model of cricket sound localization. The main advances are the inclusion of a much larger range of neuroethological detail, and the investigation of multimodal influences on the behaviour. The former allows exploration of the functionality of identif...

It has been reported that many elderly persons exhibit problems in identifying the location of fused auditory images in a test of the precedence effect in sound localization. The precedence effect involves the neural integration of multiple competing binaural temporal cues, and may reflect subtle age-related neural timing or integration problems. This study investigated whether elderly persons ...

21 Sound localization accuracy in elevation can be affected by sound spectrum alteration. 22 Correspondingly, any stimulus manipulation that causes a change in the peripheral representation 23 of the spectrum may degrade localization ability in elevation. The present study examined the 24 influence of sound duration and level on localization performance in cats with the head 25 unrestrained. Tw...
