情绪的动机维度模型认为,高动机强度的情绪窄化(narrow)认知加工而低动机强度的情绪扩展(broaden)认知加工。该理论超越了先前对效价和唤醒两大情绪维度的二分法,证明了情绪的动机维度对注意、记忆等认知加工产生扩展和窄化效应,深化了积极情绪的扩展一建设理论,有助于深入理解情绪与认知的交互作用。未来研究应建立动机维度的操作性定义,并进一步发展出诱发不同动机维度情绪的标准化刺激材料或任务。
Previous theories emphasizing valence and arousal dimensions of affect directed a number of experimental researches, but they have always gave rise to some controversies. Recently the motivational dimensional model of affect was proposed, in a word, affect of low motivational intensity broadens cognitive processes, whereas affect of high motivational intensity narrows cognitive processes. This model demonstrated that narrowing and broadening effects of other dimensions of affect to attention, memory processes and so on, which go beyond dichotomy of valence and arousal. In summary, this model have significant implications in understanding the interaction of cognition and emotion and must be further tested in future. It is critical to explain the operational definition of motivational dimension and develop relevant standard stimuli materials or tasks.
