    问答题
    What is the function of the affective filter?

    正确答案： According to the affective filter hypothesis, comprehensible input may not be utilized by second language acquirers if there is a “mental block” that prevents them from fully profiting from it. The affective filter acts as a barrier to acquisition: if the filter is “down”, the input reaches the LAD and becomes acquired competence; if the filter is “up”, the input is blocked and does not reach the LAD. Thus “input is the primary causative variable in SLA, affective variables acting to impel or facilitate the delivery of input to the LAD.”
