The impact of differences in maternal self-efficacy and infant difficulty on mothers' sensitivity to small changes in the fundamental frequency of an audiotaped infant's cry was explored in 2 experiments. The experiments share in common experimental manipulations of infant difficulty, a laboratory derived measure of maternal efficacy (low, moderate, and high illusory control), and the use of signal detection methodology to measure maternal sensory sensitivity. In Experiment 1 (N = 72), easy and difficult infant temperament was manipulated by varying the amount of crying (i.e., frequency of cry termination) in a simulated child-care task. In Experiment 2 (N = 51), easy and difficult infant temperament was manipulated via exposure to the solvable or unsolvable pretreatment of a learned helplessness task to mirror mothers' ability to soothe a crying infant. In both experiments, only mothers with high illusory control showed reduced sensory sensitivity under the difficult infant condition compared with the easy infant condition.
在两项实验中,研究了母亲自我效能感差异和婴儿难养程度对母亲对录音中婴儿哭声基频微小变化的敏感性的影响。这两项实验的共同之处在于对婴儿难养程度的实验操纵、一种实验室得出的母亲效能感测量指标(低、中、高错觉控制),以及使用信号检测方法来测量母亲的感官敏感性。在实验1(N = 72)中,通过在模拟育儿任务中改变哭闹量(即哭声终止频率)来操纵婴儿气质的难易程度。在实验2(N = 51)中,通过让婴儿接触习得性无助任务的可解决或不可解决的预处理来操纵婴儿气质的难易程度,以反映母亲安抚哭闹婴儿的能力。在两项实验中,与易养婴儿条件相比,只有具有高错觉控制的母亲在难养婴儿条件下表现出较低的感官敏感性。
