Abstract

This chapter introduces a psychological mechanism that involves a close link between perception and motor behaviour. It focuses on a mechanism called the brain stem reflex, which refers to a process whereby an emotion is aroused in a listener because an acoustic feature — such as sound intensity or roughness of timbre — exceeds a certain cut-off value for which the auditory system has been designed by natural selection to quickly alert the brain. It is a kind of ‘override’ system, which is activated when an event seems to require first-priority attention. Brain stem reflexes are said to be ‘hard-wired’: they are quick, automatic, and unlearned.

本章介绍了一种涉及感知和运动行为之间密切联系的心理机制。它关注的是一种被称为脑干反射的机制,它指的是听者的情绪被激发的过程,因为一种声学特征——比如声音强度或音色的粗糙度——超过了一定的临界值,听觉系统是由自然选择设计的,可以迅速提醒大脑。这是一种“覆盖”系统,当一个事件似乎需要第一优先关注时,它就会被激活。脑干反射被认为是“天生的”:它们是快速的、自动的、非习得的。
