The Effects of Voice Changes on Orienting and Immediate Cognitive Overload in Radio Listeners

摘要: An experiment was designed to identify the voice change as a specific structural feature of radio that causes automatic allocation cognitive resources message encoding. The cardiac orienting response (OR) used an indication this resource allocation. It hypothesized listeners would exhibit ORs in changes and associated result momentary overload. Data were collected from 62 participants they listened nine messages varied number contained. Results show robust suggest does not habituate over course 2-minute messages. Furthermore, auditory recognition data only overload, but severity overload depends on total message.
