能动性理论--控制自己行为及其效果的感觉--强调知觉或认知方面。这项研究同时解决了这两个方面的手指敲击范例。这些任务要求参与者检测他们的敲击与计算机控制的音调的同步何时改变为自我控制的音调产生，或者相反。为了进行比较，在这些主动敲击条件下记录的音调序列也在被动收听条件下呈现，在被动收听条件下，参与者必须检测从计算机到人类控制的过渡，反之亦然。应用信号检测理论分离灵敏度和偏倚。感官运动的线索机构被发现，以增加灵敏度的主动条件相比，被动的条件下，只提供知觉线索。偏差分析显示，倾向于属性的行动效果自我控制。因此，对能动性的判断依赖于真实的感觉运动线索，但也可能受到认知偏差的影响。（PsycInfo数据库记录（c）2016阿帕，保留所有权利）
Theories of agency--the feeling of being in control of one's actions and their effects--emphasize either perceptual or cognitive aspects. This study addresses both aspects simultaneously in a finger-tapping paradigm. The tasks required participants to detect when synchronization of their taps with computer-controlled tones changed to self-controlled production of tones, or the reverse. For comparison, the tone sequences recorded in these active tapping conditions were also presented in passive listening conditions, in which participants had to detect the transition from computer to human control, or vice versa. Signal detection theory was applied to separate sensitivity from bias. Sensorimotor cues to agency were found to increase sensitivity in the active conditions compared with the passive conditions, which provided only perceptual cues. Analysis of bias revealed a tendency to attribute action effects to self-control. Thus, judgments of agency rely on veridical sensorimotor cues but can also be subject to cognitive bias.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
