Two independent experiments (N = 30 and N = 24) investigated the effects of concurrent task loads on the recognition of faces displaying emotions. The study aimed to explore a possible resolution for an apparently discrepant finding in the literature regarding the impact of such loads on recognition of facial emotions. Faces displaying different emotions were presented, with or without a concurrent load, until the facial stimuli were correctly labelled to criterion in terms of the displayed emotion. Participants were then presented with elements from the faces (i.e. eyebrows, eyes, and mouth). When participants had to complete the concurrent task as well as the facial recognition task, they did not respond equally to the separate facial elements, and over-selected to the mouth when recognising facial expressions of emotion. The findings relating to the impact of the concurrent load tasks on correct labelling of the facial elements with respect to the emotional faces are discussed in terms of the impact of cognitive load on the production of over-selectivity and the recognition of faces displaying emotions in complex situations, and the implications for those with a developmental disability.
两项独立实验（N = 30和N = 24）研究了并发任务负荷对识别表达情绪的面部的影响。该研究旨在探索一种可能的解决方案，以解决文献中关于此类负荷对面部情绪识别影响的一个明显矛盾的发现。呈现显示不同情绪的面部，有或没有并发负荷，直到面部刺激根据所显示的情绪被正确标记到标准。然后向参与者呈现面部的各个部分（即眉毛、眼睛和嘴巴）。当参与者必须同时完成并发任务和面部识别任务时，他们对不同的面部部分反应并不相同，并且在识别情绪面部表情时过度选择了嘴巴。从认知负荷对过度选择性产生的影响以及在复杂情况下对显示情绪的面部识别的影响，以及对发育障碍者的影响等方面，讨论了并发负荷任务对情绪面部的面部部分正确标记的影响的相关发现。
