Individuals with autism spectrum disorder (ASD) often exhibit disordered speech prosody, but sources of disordered prosody remain poorly understood. We explored patterns of temporal alignment and prosodic grouping in a speech-based metronome repetition task as well as manual coordination in a drum tapping task among Cantonese speakers with ASD and…

The metronome is a frequently used time-keeping tool in music instrument practice. However, if its speed is set beyond a comfortable level for the performer, their eye movement (EM) patterns can betray pressure that might have been placed on the visual processing system. The patterns of the eyes moving forward or back, (saccades); when the eye…

Mind wandering is a pervasive feature of human cognition often associated with the withdrawal of task-related executive control processes. Here, we explore the possibility that, in tasks requiring executive control to sustain consistent responding, moments of mind wandering could be associated with moments of increased behavioral variability. To…

Wilhelm Wundt (1832-1920) believed that consciousness was represented by the interconnection of psychical processes comprised of temporal elements and compounds. To explore these processes, Wundt used a metronome to measure the amount of information that passed into consciousness across time. The current project replicated some of his procedures,…

Five experiments are reported in which standard naming and tempo-naming tasks were used to investigate mechanisms of control over the time course of lexical processing. The time course of processing was manipulated by asking participants to time their responses with an audiovisual metronome. As the tempo of the metronome increased, results showed…

In four experiments, participants performed sentence comprehension tasks simultaneously with bimanual coordination. Half of the sentences described events that could not be performed by a human (non-performable) and half described actions that could be performed by a human (performable). Effects of sentence type on coordination were indexed by…
