This paper introduces a synthetic study which investigates the role of shaking behavior in object category acquisition. By shaking objects with several holding positions and obtaining the amplitude spectrums of the auditory signal, a robot with poor control ability can acquire object categories such as rigid objects, paper materials, and PET bottles with water. The result indicates the possibli...

Pitch perception is critical for the perception of speech and music, for object identification, and for auditory scene analysis, whereby representations are derived for each sounding object in the environment from the complex sound wave that reaches the ears. The perceived pitch of a complex sound corresponds to its fundamental frequency. However, removal of energy at the fundamental does not a...

Auditory objects are detected if they differ acoustically from the ongoing background. In simple cases, the appearance or disappearance of an object involves a transition in power, or frequency content, of the ongoing sound. However, it is more realistic that the background and object possess substantial non-stationary statistics, and the task is then to detect a transition in the pattern of on...

Auditory icons – or environmental sounds – have the potential to convey information by non-verbal means quickly and accurately. In addition, human listeners are quick to determine many qualities of an auditory object, such as location, distance, size, and motion, from acoustics of the signal. An experiment tests these two coupled assumptions in a controlled laboratory context. Stimuli consisted...

Past neuroimaging studies have documented discrete regions of human temporal cortex that are more strongly activated by conspecific voice sounds than by nonvoice sounds. However, the mechanisms underlying this voice sensitivity remain unclear. In the present functional MRI study, we took a novel approach to examining voice sensitivity, in which we applied a signal detection paradigm to the asse...

This work considers bases for working memory for non-verbal sounds. Specifically we address whether sounds are represented as integrated objects or individual features in auditory working memory and whether the representational format influences WM capacity. The experiments used sounds in which two different stimulus features, spectral passband and temporal amplitude modulation rate, could be c...

background and aim: auditory processing disorders may have detrimental consequences on a child’s life, if undiagnosed and untreated. the multiple auditory processing assessment (mapa), as a valid model, has been introduced for central auditory processing assessment and diagnosis in school children. the purpose of this study was to design and evaluate the persian version of mapa for auditory pro...
