This review discusses behavioral, neuroscientific, and cognitive research connecting these bodily movements with emotive responses. General bodily feedback theories of emotion have suggested that manipulated facial expressions and postures influence emotive reactions to stimuli as well as physiological responses such as heart rate, skin conductance, and the temperature of blood entering the brain. More recent evidence suggests that manipulated bodily states influence prefrontal cortical activation and amygdala activation. Even further evidence has suggested that manipulated bodily states influence cognitive processes, such as the speed at which individuals read emotional content, the speed at which they classify information as emotional, and the extent to which they determine emotional information as threatening. Bodily feedback theories may also...

This model accepts the original theory's proposal that a sufficient cognitive inconsistency causes the negative affective state of dissonance. It extends the original theory by proposing why cognitive inconsistency prompts dissonance and dissonance reduction. After reviewing past theoretical and empirical developments on cognitive dissonance theory, we describe the action‐based model and present results from behavioral and physiological experiments that have tested predictions derived from this model. In particular, this evidence converges with recent neuroscience evidence in suggesting that the anterior cingulate cortex and left prefrontal cortical region are involved in conflict detection and resolution, respectively. We end by reviewing research on individual differences in dissonance arousal and reduction, and present a new measure designed to assess these individual differences.

The role that gender might play in moderating this relationship and what particular medial prefrontal cortex subregion(s) might be implicated is unclear. Magnetic resonance imaging was used to assess dorsal, ventral, and anterior cingulate regions of the medial prefrontal cortex in a normative sample of male and female adults. The Depression, Anxiety, and Stress Scale (DASS) was used to measure these three variables. Voxel-based morphometry was used to test for correlations between medial prefrontal gray matter volume and depressive traits. The dorsal medial frontal cortex was correlated with greater levels of depression, but not anxiety and stress. Gender moderates this effect: in males greater levels of depression were associated with lower dorsal medial prefrontal volumes, but in females no relationship was observed. The results indicate that even within a non-clinical sample, male participants with higher levels of depressive traits tend to have lower levels of gray matter volume in the dorsal medial prefrontal cortex. Our finding is consistent with low dorsal medial prefrontal volume contributing to the development of depression in males. Future longitudinal work is needed to substantiate this possibility.

More recently, our motivational intensity model suggests that this past work had confounded valence with motivational intensity. Research derived from this model supports the idea that motivational intensity, rather than affective valence, explains much of the variance emotions have on cognitive scope. However, the motivational intensity model is limited in that the empirical work has examined only positive affects high in approach and negative affects high in avoidance motivation. Thus, perhaps only approach-positive and avoidance-negative states narrow cognitive scope. The present research was designed to clarify these conceptual issues by examining the effect of anger, a negatively valenced approach-motivated state, on cognitive scope. Results revealed that anger narrowed attentional scope relative t...

However, little is known about variables that influence the intensity of these negative affective responses. Two studies fill this void by incorporating work on approach- and withdrawal-related emotional states and their associated cortical activations. Study 1 found that following ostracism anger related directly to relative left frontal cortical activation. Study 2 used unilateral hand contractions to manipulate frontal cortical activity prior to an ostracizing event. Right-hand contractions, compared to left-hand contractions, caused greater relative left frontal cortical activation during the hand contractions as well as ostracism. Also, right-hand contractions caused more self-reported anger in response to being ostracized. Within-condition correlations revealed patterns of associations between ostracism-induced frontal asymmetry and emotive responses to ostracism consistent with Study 1. Taken together, these results suggest that asymmetrical...
