Emotion Disconnections Affect Awareness

Major Depressive Disorder Positive Attenuation Hypothesis Negative Potentiation Hypothesis (Aaron Beck) Emotion-Context Insensitivity (ECI) Hypothesis (Rottenberg)

Positive Attenuation Hypothesis (PAH) Begins with low levels of positive mood Weakened responses to positive stimuli – Anhedonia, apathy, fatigue Less likely to seek out or consume rewards

Negative Potentiation Hypothesis (NPH) Begins with high levels of negative mood Greater reactivity to negative emotional stimuli Negative worldview leads people to experience more negative emotions in response to unpleasant stimuli

Emotion Context Insensitivity (ECI) Restricted range of positive and negative emotions – Weakened responses to both positive and negative stimuli Emotions not appropriate for context Partially supports PAH

Research Says! PAH: Depressed v. Control – Less positive responses to rewarding stimuli – Deficits in activation of left frontal lobe NPH: Depressed v. Control – Greater SCR to negative social scenarios – More negative attributions – BUT, show weakened amygdala responses to fearful faces – BUT, weakened SCR and startle to unexpected noise

For ECI, Research Says! Across sad, amusing and neutral contexts, people with most similar facial expressions and physiological reactions: – Highest depression severity – Depressed for longest period of time – Least likely to recover 6 months later (Rottenberg, Kasch, et al. , 2002)

Evidence for ECI Hypothesis Currently depressed, formerly depressed, healthy controls Film Clips: Happy, Sad DV: Subjective feelings

Evidence for ECI Hypothesis Happy Neutral Sad Self-reported Happiness 9 7 5 3 1 Depressed Recovered Control

Evidence for ECI Hypothesis Happy Neutral Sad Self-reported Sadness 9 7 5 3 1 Depressed Recovered Control

Evidence for ECI Hypothesis Supports ECI and Positive Attenuation: – Across all clips, lower positive emotions than recovered and controls – Similar sadness across 3 film clips Against ECI – More negative emotions than recovered and controls – No differences for facial expressions or physiology

Positive Emotion Persistence (PEP) Greater degree of positive emotions Increases in reward and achievement-oriented emotions Increased positive emotions across all contexts Deficiencies in Emotion Regulation – Up-regulate positive emotions – Difficulty down-regulating positive emotions (Gruber and colleagues)
