Aging Paradox Older adults show

significant decline in cognitive control abilities (Prakash et al., 2012)

High risk of cognitive decline Poor quality of life (Kramer & Erickson, 2007)

Older adults show preservation of emotion processing abilities (Charles & Carstensen,2007; Mather, 2012)

(Park et al., 2010)

Page 3: Examining Neural Correlates of Mindfulness and Emotion Regulation4.7

Aging Paradox Aging associated with more positive overall emotional

well-being and greater emotional stability (Carstensen et al., 2011)

Older adults report lower levels of negative emotion and higher levels of positive emotion (Stawski et al., 2008)

Rheault & McGeeney, 2011 Carstensen et al., 2011

Socioemotional Selectivity Theory

(SST) As perceived time left in life shrinks with age, people are more motivated to regulate emotions (Carstensen, Isaacowitz, & Charles, 1999)

Carstensen, 1995

Page 5: Examining Neural Correlates of Mindfulness and Emotion Regulation4.7

What is emotion regulation?o All conscious and unconscious strategies used to increase,

maintain, or decrease one or more components of an emotional response

Antecedent-focused strategies o Situation selectiono Situation modificationo Attention deploymento Cognitive change

Response-focused strategies

o Response modulation

Types of Emotion Regulation

Gross, 1998

Page 6: Examining Neural Correlates of Mindfulness and Emotion Regulation4.7

Cognitive Emotion Reappraisal

What is cognitive emotional reappraisal? o Altering one’s interpretation of the meaning of a situation so

as to change its emotional impact (Gross, 1998)

Effective and associated with more positive emotion, less negative emotion and greater levels of well-being (Gross & John, 2003)

Page 7: Examining Neural Correlates of Mindfulness and Emotion Regulation4.7

Cognitive Emotion Reappraisal: Young Adults

Emotion reappraisal consistently reduces subjective experience of negative emotion

Emotional reappraisal recruits regions of the prefrontal cortex

Research on the effects of emotion reappraisal on the elderly is limited

Ochsner et al., 2002; 2004

Page 8: Examining Neural Correlates of Mindfulness and Emotion Regulation4.7

Emotion Regulation: Older Adults

Self-report data has suggested that older adults have lower levels of difficulty in emotion regulation overall compared to young (Orgeta, 2009)

Regulating negative emotions has been shown to be less costly in older adults in their cognitive performance than younger adults (Scheibe & Blanchard-Fields, 2009)

Relative to younger adults, older adults are less successful using reappraisal to decrease unpleasant emotion (Opitz et al., 2010)

Page 9: Examining Neural Correlates of Mindfulness and Emotion Regulation4.7

Mindfulness What is Mindfulness?

o Mindfulness training vs. dispositional mindfulness o Purposeful, non-judgemental, attentional awareness to

present moment experiences (Kabat-Zinn, 1990)

Evidence for Dispositional Mindfulnesso Enhances quality of life and brain function connectivity (Urry et

al., 2006)o Reduces anxiety, depression, pain and emotion based

disorders (Grossman et al., 2004)o Reduction in emotional reactivity and better regulation of

emotions (Creswell et al., 2007)o Those with higher levels of trait mindfulness are better

able to regulate their emotions through emotion reappraisal (Modinos, Ormel, & Aleman, 2009)

Page 10: Examining Neural Correlates of Mindfulness and Emotion Regulation4.7

Mindfulness and Emotion Control

Mindfulness associated with enhanced controlled, top-down processing in emotional contexts, older adults show an advantage

Affect-Labeling Task

Creswell et al., 2007

Page 11: Examining Neural Correlates of Mindfulness and Emotion Regulation4.7

Mindfulness and Emotion Control

Higher mindfulness disposition was associated with:o Decreased amygdala

activation o Increased PFC recruitment

Areas of lateral PFC show greatest structural and functional decline in aging (Raz et al., 2004)

Higher levels of dispositional mindfulness may result in enhanced cognitive control and better cognitive emotion reappraisal

Prakash et al., 2012

Page 12: Examining Neural Correlates of Mindfulness and Emotion Regulation4.7

Methods Cross-sectional analysis

o Older Adults N = 50, Younger Adults N = 50

Page 13: Examining Neural Correlates of Mindfulness and Emotion Regulation4.7

Dispositional Mindfulness Measure

Mindful Attention and Awareness Scale (MAAS) (Brown & Ryan, 2003)o 15-item questionnaire designed to capture attention and

awareness in daily lifeo Items rated on a six-point likert scale: 1 = almost

always; 6 = almost never

Example items:o “I perceive my feelings and emotions without having to react to

them”o “When I do things, my mind wanders off and I’m easily

distracted”

Higher scores reflect higher levels of mindfulness disposition

Page 14: Examining Neural Correlates of Mindfulness and Emotion Regulation4.7

Emotion Regulation Training Session

Focus on the picture while thinking of something to tell yourself that will help you feel less negative towards it

For every picture following the regulate cue you should ask yourself, “What can I tell myself in order to feel less distressed or negative?”

Example: Viewing a picture of someone who is illo It will soon be resolved, help is on the wayo Maybe it’s not as painful as it lookso Maybe they are giving him/her drugs so they aren’t in paino Maybe this is just for TV so it’s not real

Actively try to convince yourself and really believe your reappraisal so you decrease how negative you feel as much as possible

Discussion Behavioral association between Mindfulness Disposition

and Cognitive Emotion Reappraisalo Older adults seem to have a more positive bias when

subjectively rating neutral images

Neural correlates of Cognitive Emotion Reappraisal in older and young adultso Older and younger adults have enhanced PFC recruitment

which is indicative of successful emotion regulation, the insular cortex activation is indicative of bottom-up, emotional reactivity

Age-related differences in Dispositional Mindfulness o Older adults report significantly higher levels of dispositional

mindfulness than younger adults

Page 31: Examining Neural Correlates of Mindfulness and Emotion Regulation4.7

Discussion Association between Mindfulness Disposition and

Cognitive Reappraisal Successo Significant negative correlation between dispositional

mindfulness and successful cognitive reappraisal of negative emotions in younger adults

o Would FFMQ be better to correlate with cognitive reappraisal success?

Neural correlates between Mindfulness Disposition and Cognitive Emotion Reappraisalo Older and younger adults with higher levels of dispositional

mindfulness display significant functioning of cortical brain regions associated with higher-level, top-down cognitive control and attention

o This is evidence for increased emotion regulation abilities via mindfulness

Page 32: Examining Neural Correlates of Mindfulness and Emotion Regulation4.7

Future Directions and Implications

Collect 1 last older adult!

Rerun correlation between mindfulness disposition and cognitive reappraisal success using FFMQ?

Reanalyze data to determine neural correlates of mindfulness disposition and cognitive reappraisal success

Mindfulness represents a promising holistic approach to enhancing basic emotion-cognition processes

Future work is needed to develop a more refined understanding of cognitive, affective, and neural processes in aging and their potential malleability to neuroplasticity-based approaches like mindfulness

Ultimately, establish a new, integrative approach to inspire future research and clinical practice in the aging field
