The present study investigated the identification of geminate and singleton consonants in Japanese by native Korean learners of Japanese. Moreover, the present study analyzed the relationship between the learners’ identification errors and timing control factors. Results revealed a geminate insertion phenomenon, along with a systematic phonetic and perceptual explanation for the phenomenon. The...

In bistable vision, subjective perception wavers between two interpretations of a constant ambiguous stimulus. This dissociation between conscious perception and sensory stimulation has motivated various empirical studies on the neural correlates of bistable perception, but the neurocomputational mechanism behind endogenous perceptual transitions has remained elusive. Here, we recurred to a gen...

In speech error research discrepant results have been obtained depending on the research tool employed. While traditionally errors have been identified perceptually, acoustic and articulatory measurements have come to different conclusions about the characteristics of errors. This has led to renewed concerns about perceptual biases in transcription records on the one hand and the comparability ...

Five experiments investigated the influence of cognitive and linguistic factors on the integration of color and letter-shape information. Subjects were briefly presented strings of colored letters that varied in pronounceability and familiarity. Detection and search tasks required subjects to identify the color of predesignated target letters. It was proposed that errors in integrating color an...

Congenital amusia is a musical disorder characterized by impaired pitch perception. To examine to what extent this perceptual pitch deficit may compromise singing, 11 amusic individuals and 11 matched controls were asked to sing a familiar tune with lyrics and on the syllable /la/. Acoustical analysis of sung renditions yielded measures of pitch accuracy (e.g., number of pitch errors) and time ...

This paper investigates self-monitoring for speech errors by means of consonant identification in speech fragments excised from speech errors and their correct controls, as obtained in earlier experiments eliciting spoonerisms. Upon elicitation, segmental speech errors had been either not detected, or early detected or late detected and repaired by the speakers. Results show that misidentificat...

Peripheral vision is fundamentally limited not by the visibility of features, but by the spacing between them [1]. When too close together, visual features can become "crowded" and perceptually indistinguishable. Crowding interferes with basic tasks such as letter and face identification and thus informs our understanding of object recognition breakdown in peripheral vision [2]. Multiple propos...

One approach to gaining a better understanding of how we perceive the world is to assess the errors that human and nonhuman animals make in perceptual processing. Developmental and comparative perspectives can contribute to identifying the mechanisms that underlie systematic perceptual errors often referred to as perceptual illusions. In the visual domain, some illusions appear to remain consta...

Purpose: To verify children’s auditory-perceptual performance regarding the identification of contrasts among stop; to identify which phonemes and contrasts provide greater or lesser perceptual difficulty; and to verify age-related influence in auditory-perceptual accuracy. Methods: Information regarding the auditory-perceptual performance of 59 children (30 male and 29 female) in a task of ide...

Corollary discharge (CD) is hypothesized to provide the movement information (direction and amplitude) required to compensate for the saccade-induced disruptions to visual input. Here, we investigated to what extent these conveyed metrics influence perceptual stability in human subjects with a target-displacement detection task. Subjects made saccades to targets located at different amplitudes ...
