behavioural mimicry in dyadic interactions
will often synchronize nonverbal behaviour
similar postures, mannerisms, facial expressions, vocal cues etc
often non-conscious, unintentional, effortless
behavioural mimicry signals… and fosters…
signals affiliative intent
fosters liking
mimicry = more likely to occur when…
we feel rapport with other person
we hold affiliative intent
when our needs for affiliation have been thwarted
when mimicry doesn’t lead to liking
when made to mimic a disliked person
when our partner is engaging in too much mimicry
getting on the same wavelength
we may see synchronization at the NEURAL LEVEL too
neural synchronization study: phase 1
Ps watched ambiguous movie clip in fMRI scanner
recorded their brain activation
neural synchronization study: phase 2
consensus-building conversation in groups
neural synchronization study: phase 3
re-watch original clip and new clips from same movie
neural synchronization study results
conversation synchronizes brain activity within groups
see this both for the original clip AND the new clips
consensus convo gives new shared frame by which to see the clip
hyperscanning
collecting fMRI or EEG data from 2 people simultaneously
technique for assessing brain-to-brain synchrony
neural synchrony is higher in…
romantic partners compared to strangers
higher during moments of social gaze (independent of speech duration and convo content)
for strangers, overall duration of social gaze positively correlated with neural synchrony
partners also develop _________ ________ of the world at large
shared perceptions
this is called SHARED REALITY
shared reality statements
through our discussions, we often develop a joint perspective
we typically share the same thoughts and feelings about things
events feel more real when we experience them together
we often feel like we have created our own reality
what predicts feelings of closeness in relationship?
shared reality
threat to shared reality study setup
phase 1: threat to shared reality
a. determine what each partner’s “sensory style” is through having them rate fabrics, foods, colours
b. either a 31% or 82% match
phase 2: joint decision making task
“choose a painting to take home”
threat to shared reality results
couples low on baseline measure of shared reality respond to experimental threats to sense of shared reality by engaging in MOTIVATED BEHAVIOUR to REAFFIRM their shared identity
ie. vocalize agreement, finish each other’s ideas, more dyad-specific references
coordination of brain activity may enable extremely…
rapid back and forth of conversation
modal conversational response time = 200 ms
modal conversational response time
200 ms
minimizing time between turns requires…
a lot of prediction
i. figuring out where partner is headed
ii. preparing appropriate response in advance
iii. anticipating when partner is likely to end their turn
iv. anticipating partner’s reaction
response times in turn taking can…
convey how well one mind is able to predict another
signals extent of social connection
turn-taking in conversations round robin study
rotate through conversational partners
later, privately rate OVERALL and MOMENT-BY-MOMENT CONNECTION during interactions
faster response times positively predict ENJOYMENT and SOCIAL CONNECTION
- also true of convos with friends
turn-taking in conversations round robin study: connection best predicted by…
PARTNER response times
the quicker your partner responds to you, the more connected you feel
