Temporal Relationship of Top-down and Bottom-up Processing in Tone Perception
نویسندگان
چکیده
Both the top-down and bottom-up processing are identified in language comprehension: the top-down processing depends on previous language experience and the bottom-up processing depends on instant language inputs. In speech perception, both types of processing are needed while perceiving pitch variations as lexical tones. In this paper, based on three ERP experiments, we propose a temporal model unifying both types of processing in a parallel way. These two types of processing, existing in both the early and late time windows, modulate the degrees of the general left lateralization of different ERP components (N1, P2, and N400).

Event-Related Potentials of Bottom-Up and Top-Down Processing of Emotional Faces
Introduction: Emotional stimulus is processed automatically in a bottom-up way or can be processed voluntarily in a top-down way. Imaging studies have indicated that bottom-up and top-down processing are mediated through different neural systems. However, temporal differentiation of top-down versus bottom-up processing of facial emotional expressions has remained to be clarified. The present st...
متن کاملTemporal relation between top-down and bottom-up processing in lexical tone perception
Speech perception entails both top-down processing that relies primarily on language experience and bottom-up processing that depends mainly on instant auditory input. Previous models of speech perception often claim that bottom-up processing occurs in an early time window, whereas top-down processing takes place in a late time window after stimulus onset. In this paper, we evaluated the tempor...
متن کاملThe effect of bottom-up and top-down auditory program training on the development of children's auditory processing skills
Although there have been several previous investigations on the role of auditory training for the development of auditory processing skills, it still remains unknown whether children with auditory processing difficulties can get improved auditory skills after exposure to a multi-modal training experience comprising both visual and tactile stimuli. The present study, therefore, attempted to use ...

Listening is regarded as an interactive process involving decoding of information. This study was launched to find out the impact of bottom-up (BU) and top-down (TD) techniques on Iranian lower and upper intermediate learners’ listening comprehension. We selected a total of 120 participants in six intact classes, three lower intermediate and three upper intermediate. The proficiency level of th...
