The Relationship

In this paper, a variable-focus ultrasonic liquid lens controlled by the external voltage is demonstrated. That is, the liquid lens can be reshaped with the external voltage, which will cause the focal length to change. The relationship between liquid lens’ shape and the control voltage was obtained. The influence factors of the response time were researched. And the distribution of the ultrasonic field after the lens under different external control voltages was simulated.

Abstract. The Sternberg short-term memory scanning task has been used to unveil cognitive operations involved in time perception. Participants produce time intervals during the task, and the researcher explores how task performance affects interval production – where time estimation error is the dependent variable of interest. The perspective of predictive behavior regards time estimation error as a temporal prediction error (PE), an independent variable that controls cognition, behavior, and learning. Based on this perspective, we investigated whether temporal PEs affect short-term memory scanning. Participants performed temporal predictions while they maintained information in memory. Model inference revealed that PEs affected memory scanning response time independently of the memory-set size effect. We discuss the results within the context of formal and mechanistic models of short-term memory scanning and predictive coding, a Bayes-based theory of brain function. We state the hypothesis that our finding could be associated with weak frontostriatal connections and weak striatal activity.
