Perceptual Discrimination of Prosodic Types
A perceptual discrimination test was conducted to investigate whether humans can discriminate prosodic types solely based on suprasegmental acoustic cues. Excerpts from Chinese, English, Spanish, and Japanese, differing in lexical accent types and rhythm types, were used. From these excerpts, “source” signals of the source-filter model, differing in F0, intensity, and HNR, were created and used...
متن کاملPerceptual learning on orientation and direction discrimination
Two experiments were conducted to determine the extent to which perceptual learning transfers between orientation and direction discrimination. Naive observers were trained to discriminate orientation differences between two single-line stimuli, and direction differences between two single-moving-dot stimuli. In the first experiment, observers practiced the orientation and direction tasks along...
متن کاملBilingual Infants Demonstrate Perceptual Flexibility in Phoneme Discrimination but Perceptual Constraint in Face Discrimination
Perceptual narrowing is a highly significant development associated with the first year of life. It conventionally refers to an orientation toward nativeness whereby infant's perceptual sensitivities begin to align with the phonetic properties of their native environment. Nativeness effects, such as perceptual narrowing, have been observed in several domains, most notably, in face discriminatio...
متن کاملActive Vision and Perceptual Memory
Today’s robotics applications require complex, real-time, high-bandwidth sensor systems. Although many such systems have been developed [12][14][17][10], integrating them into an autonomous agent architecture remains an area of active research. We will discuss how active perception systems can be integrated with agent architectures to perform complex tasks. We present an active stereo vision sy...
متن کاملTask-dependent transfer of perceptual to memory representations during delayed spatial frequency discrimination
Discrimination thresholds were obtained using a delayed spatial frequency discrimination task. In Experiment 1, we found that presentation of a mask 3 s before onset of a reference Gabor patch caused a selective, spatial frequency dependent interference in a subsequent discrimination task. However, a 10 s interval abolished this masking effect. In Experiment 2, the mask was associated with a se...
