Temporal relation between top-down and bottom-up processing in lexical tone perception

Temporal 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...

Temporal Relationship of Top-down and Bottom-up Processing in Tone Perception

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 mode...

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...

Individual Differences in Top-down and Bottom-up Prominence Perception

The perception of prosody, like other aspects of speech perception, relies on a combination of bottom-up and top-down information. In the context of prominence perception, the present study explored the interaction of these two types of cues, and individual variation in their effects on listeners. In a “naïve prosody transcription” task, 120 listeners gave prominence ratings to verbs and object...
