The structure of current affect: Controversies and emerging consensus

For some years now, emotion researchers have debated a series of issues related to the structure of consciously experienced affective states. The present article reviews evidence that current affective experience can be summarized by a structure that is anchored by two bipolar but independent dimensions of experience, pleasure and activation. Four issues have presented themselves as central to the nature of this structure: the number of dimensions necessary to describe the space, the bipolarity of the dimensions, whether the structure displays a circumplex shape, and the definition of the activation dimension. Points of consensus and the remaining controversies regarding each issue are presented.
