为了研究恐惧是否会影响反应的强度，12个害怕动物的个体（5个害怕蛇，7个害怕蜘蛛）被要求尽快决定是否有一个来自异常类别的动物目标出现在3x4的项目（动物）搜索阵列中。动物种类有蛇、蜘蛛和猫。测量响应力，单位为牛顿。结果表明，当恐惧的动物作为目标时，反应的强度大于当它作为干扰物时。这一发现得到了刺激诱发心率变化的证实。我们的研究结果加强了这样一种观点，即把注意力集中在一个单一的、令人恐惧的动物身上会导致体力的增加。
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 x 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.
