Participants viewed depictions of single three-dimensional Shepard–Metzler objects situated within a sphere. ![]() ![]() This study used functional magnetic resonance imaging (fMRI) to investigate the neural mechanisms underlying two types of spatial transformations: imagined object rotations and imagined rotations of the self about an object. This finding also casts doubt on the conventional marketing wisdom that any exposure is good exposure. Finding that negative affective responses are specifically generated for ignored stimuli points to a new functional role for attention and elaborates the link between attention and emotion. Furthermore, this emotional devaluation of distracting stimuli was robust across different emotional contexts and response scales. Previously ignored patterns were evaluated more negatively than either previously attended or novel patterns. ignoring) used to process each pattern in a visual selection task. Here we show that evaluation of the emotional tone (cheery/dreary) of complex but meaningless visual patterns can be modulated by the prior attentional state (attending vs. Al- though there is ample evidence that emotional stimuli modulate attentional processes, it is not known whether attention influences emotional behavior. Taken together, these results suggest that highly self-relevant information captures attention through neural mechanisms that are comparable to those engaged during explicit self-reflection, namely via recruitment of CMS structures.ĭistinct complex brain systems support selective attention and emotion, but connections between them suggest that human behavior should reflect reciprocal interactions of these systems. In Experiment 2, we examined CMS activity during passive viewing of personal semantic facts (such as subjects’ own first names). Results revealed increasing activity in CMS with increasing self-relevance, but only during explicit ratings of self-relevance. In Experiment 1, subjects rated trait adjectives for social desirability and for self-relevance. In this paper, we report findings from two experiments that manipulated requirements for self-reflection. A common thread among previous reports has been reliance on experimental tasks that encourage or require online self-referential processing. Moreover, items rated as self- relevant produce increased activity in these regions relative to items that are deemed not self-relevant. Recent neuroimaging work has observed activity in cortical midline structures (CMS) such as medial prefrontal and posterior cingulate cortices during self-referential processing. ![]()
