Duality Models in Social Psychology: From Dual Processes to Interacting Systems

Dual-system models explain social cognition and behavior as a joint function of 2 interconnected mental faculties, each operating according to different principles. In this article, we use the Reflective-Impulsive Model as an example and first describe 3 major advantages of dual-system models, i.e., their integrative power, their foundation in well-established constructs of cognition and neuroscience; and the ease with which they can explain the interplay of judgments and nonjudgmental processes. We then turn to current debates on the adequate number of systems, as well as on the role of freedom and consciousness. We conclude by stating that dual-system models are versatile tools to integrate existing findings and to stimulate new research in social cognition and beyond.

Contextual Influences on Implicit Evaluation: A Test of Additive Versus Contrastive Effects of Evaluative Context Stimuli in Affective Priming

Drawing on two alternative accounts of the affective priming effect (spreading activation vs. response interference), the present research investigated the underlying processes of how evaluative context stimuli influence implicit evaluations in the affective priming task. Employing two sequentially presented prime stimuli (rather than a single prime), two experiments showed that affective priming effects elicited by a given prime stimulus were more pronounced when this stimulus was preceded by a context prime of the opposite valence than when it was preceded by a context prime of the same valence. This effect consistently emerged for pictures (Experiment 1) and words (Experiment 2) as prime stimuli. These results suggest that the impact of evaluative context stimuli on implicit evaluations is mediated by contrast effects in the attention to evaluative information rather than by additive effects in the activation of evaluative information in associative memory.
