What are emotions?

Short-lived phenomena – Psychological

• Alter attention, shift certain behaviors upward in response hierarchies, activate memory networks

– Physiological • Rapidly organize the responses of disparate biological

systems (e.g., facial expression, somatic muscular tonus, voice, ANS)

Levenson, 1994

Positive Emotions Serve Important Social Functions

• Family of positive emotions – Compassion, nurturant love,

awe, enthusiasm, amusement, calm, gratitude

• Facilitate: – Approach behavior – New relationships – Creativity, generation, and

expansive thinking Fredrickson, 2004; Griskevicius et al., 2010

Page 12: Effects of Brain Disease On Our Loved Ones and Relationships

Positive Emotions: Restore and Buffer

• Positive emotions: – “Undo” negative

emotional states – Counter effects of

chronic stress – Foster resilience – Are associated with lower

physiological arousal

Page 15: Effects of Brain Disease On Our Loved Ones and Relationships

Parasympathetic Activity is Advantageous

• Slower breathing: – Decreases heart rate – Increases heart rate

variability

• Higher heart rate variability is associated with: – Positive emotion – Prosocial behavior

Page 16: Effects of Brain Disease On Our Loved Ones and Relationships

Parasympathetic Tone Promotes Positive Emotion

• Lower negative emotion • Greater positive experience to neutral

situations • Higher positive mood • Greater optimism and agreeableness • Sweet spot for parasympathetic functioning?

Compassion Motivates Helping

Singer & Klimecki, 2014

Page 18: Effects of Brain Disease On Our Loved Ones and Relationships

Sharing Positive Emotions is Rewarding in the Brain

• Compassion activates reward networks

• Sharing others’ positive emotions also activates reward networks

Gratitude Helps to Sustain Close Relationships

• Important social functions • Find-remind-and-bind

theory • Gratitude solidifies

relationships with supportive, loyal partners

Algoe, 2012

Presentation Notes
Find: new relationship partners Remind: us of quality partners Bind: recipient and benefactor together
Page 20: Effects of Brain Disease On Our Loved Ones and Relationships

Awe is Good for Your Mind and Body

• Feeling of wonder when in the presence of something vast, large, or hard to grasp

• Associated with: – Cognitive restructuring – Decreased self-focused

attention – Lower inflammatory

levels

How do changes in patients’ emotions alter relationships?

Brain Diseases Change Relationships by Altering Emotion

Behavioral Variant Frontotemporal Dementia

(bvFTD) Alzheimer’s Disease

(AD)

Page 24: Effects of Brain Disease On Our Loved Ones and Relationships

Brain Lesions From Various Causes Have Similar Impact on Behavior

• Individual patients have taught us an enormous amount about brain-behavior relationships

• Diseases/tumors/ injuries that target these regions will have similar impact on thinking and behavior

Page 25: Effects of Brain Disease On Our Loved Ones and Relationships

AD • Cognitive symptoms

primary • Social and emotional

preservation • Posterior: parietal and

medial temporal

bvFTD • Socioemotional symptoms

primary • Social and emotional

impairment • Anterior: medial frontal

and insula

Page 26: Effects of Brain Disease On Our Loved Ones and Relationships

bvFTD Example: Loss of Empathy

Laboratory Measurement of Emotion

• Physiological Reactivity – Heart rate, respiration, skin

conductance, finger temperature, ear pulse, finger pulse, somatic activity, blood pressure, heart rate variability, cardiac impedance, facial EMG, pupil diameter

• Facial Behavior • Self-Report Did you feel sad while watching the film?

1 2 3 4 5 No A little A lot

Page 30: Effects of Brain Disease On Our Loved Ones and Relationships

Self-Conscious Emotions Serve Interpersonal Functions

• Social emotions – Guilt, pride, shame, and embarrassment – Social evaluation

• Embarrassment

– Emerges after violation of a social convention – Characteristic facial display and physiological

activation – Promotes reparation of disrupted social bonds

Page 31: Effects of Brain Disease On Our Loved Ones and Relationships

• Self-representations are progressively more complex across phylogeny (Povinelli & Cant, 1995)

• Self-recognition is seen in highly social species - Human infants (Papousek, 1974)

- Great apes (Gallup, 1970)

- Elephants (Plotnik, 2006)

- Dolphins (Reiss, 2001)

Self-Representations: Uniquely Human?

Page 37: Effects of Brain Disease On Our Loved Ones and Relationships

Emotional Empathy is Affect-Sharing

• Mirroring of others’ emotions – Mimicry – Autonomic simulation – Rapidly – Without conscious awareness

• Evolutionarily conserved – Present in other species – Present in human infants

• Depends on emotion generation brain systems – Insula, ACC central amygdala,

hypothalamus PAG

• Clinical observations – Intact (enhanced?) social behavior in AD

• Emotional symptoms are common – In MCI (35-85%) and AD (75%)

• Increased salience network connectivity in AD (Zhou, 2010)

– Relates to agitation, irritability, aberrant motor behavior (Balthazar, 2013)

Socioemotional Preservation in AD

• Increased emotional contagion in AD?

How do patients’ emotional changes impact caregivers’ health?

Picasso

Page 45: Effects of Brain Disease On Our Loved Ones and Relationships

Potential Costs to Caregiving

• Increased burden • Increased depression and anxiety • Lower self-rated physical health, greater

health care utilization, greater decline in cellular immune functioning

• Lower self-rated well-being • There are large individual differences in these

outcomes

Disease-Specific Impacts on Caregivers’ Language and Marital Satisfaction

• Couples in which one person had bvFTD or AD had a conversation about an area of conflict

• Caregivers of patients with bvFTD used more negative words than caregivers of patients with AD

• Couples with FTD had lower marital satisfaction than couples with AD

Ascher et al., 2009

Page 48: Effects of Brain Disease On Our Loved Ones and Relationships

Changes in Connectedness Can Accompany Disease

• Inclusion of Other in Self Scale • Decreases in inclusion predict:

– decreases in life satisfaction and – Increases in caregiver burden
