To investigate whether fear affects the strength with which responses are made, 12 animal-fearful individuals (five snake fearful and seven spider fearful) were instructed to decide as quickly as possible whether an animal target from a deviant category was present in a 3 × 4 item (animal) search array. The animal categories were snakes, spiders, and cats. Response force was measured, in newtons. The results showed that the strength of the response was greater when the feared animal served as the target than when it served as the distractors. This finding was corroborated by evoked heart rate changes to the stimuli. Our findings strengthen the argument that focused attention on a single, feared animal can lead to increases in manual force.
为了研究恐惧是否会影响反应的力度，12名害怕动物的个体（5名害怕蛇，7名害怕蜘蛛）被要求尽快判断一个3×4项（动物）搜索阵列中是否存在来自异常类别的动物目标。动物类别包括蛇、蜘蛛和猫。以牛顿为单位测量反应力。结果表明，当恐惧的动物作为目标时，反应的力度比其作为干扰物时更大。这一发现得到了对刺激的诱发心率变化的证实。我们的研究结果强化了这样一种观点，即集中注意力于单一的恐惧动物会导致手动力量增加。
