My aims
• I would like to get your views on my research
plans.
• To understand social and emotional
processing in Borderline Personality
Disorder.
• To understand the effect of psychotherapy
on Borderline Personality Disorder.

Background
Theory of mind
• The ability to understand the intentions,
desires, emotions and beliefs of another
individual.
• The Sally-Anne task

The amygdala
• Rapid response to
emotional stimuli
• Emotional arousal
• Emotional learning

Introducing BPD
• Characterised by problems with emotional
regulation
• We know that forming relationships is
something which can present challenges
• Complex interaction between environmental
and genetic factors
• The amygdala is important for emotional
regulation

Social cognition in BPD
• Increased sensitivity to facial expression in
BPD?
• Yes

The amygdala in BPD
• Structurally smaller
• “Hypersensitive”
• “Highly vigilant”

Theory of mind in BPD
Scores
• Performance on two tasks were studied in
people with BPD.

Mirror Neurons
• Neurons which fire during the performance
and observation of the same sensory action.

Mirroring and BPD
• Social development
• Simulation
• Imitation
www.abdn.ac.uk
Research questions
•
How well do people with BPD imitate (copy)
the facial expression of others?
• Intensity of simulation process as a consequence of increased
affective sensitivity?
• Would this lead to better empathy?
• Or is imitation something which presents challenges?
• How does imitation ability relate to other skills in BPD?
www.abdn.ac.uk
Social cognition
1. Attend to salient emotion
2. Understand perspective of individual,
3. Regulation of emotion
www.abdn.ac.uk
How does emotion regulation work?
• They amygdala and the prefrontal cortex
Dorsomedial
prefrontal cortex
Amygdala
Ventromedial
prefrontal cortex

Emotional regulation in BPD
• Cortico-limbic
disconnection
model
• Sensitivity to facial
expression
• Current evidence
• A risk factor?
• Cognitive
reappraisal
www.abdn.ac.uk
Performing theory of mind
1. Attend to salient emotion
2. Understand perspective of individual
3. Regulation of emotion

Research questions
• How well do people with BPD imitate (copy)
the facial expression of others?
• Intensity of simulation process as a consequence of increased
affective sensitivity?
• Would this lead to better empathy?
• Or is imitation something which presents challenges?
• How does imitation ability relate to other skills in BPD?
• How do any difficulties with regulation relate to imitation?
www.abdn.ac.uk
Mentalisation-based therapy
• Effective in the treatment of BPD
• Aims to help individual understand the
mental states of others and themselves.
• How does this therapy work?
www.abdn.ac.uk
Research questions
• How well do people with BPD imitate (copy)
the facial expression of others?
• Does psychotherapy have an effect on the
ability to imitate in BPD?
• What mechanisms does psychotherapy tap in to?
• Does psychotherapy improve imitative ability?
• What about emotional regulation?
www.abdn.ac.uk
Answering our research questions
Aim: to develop a task to detect subtle deficits
of facial imitation
• We need facial expressions that vary in a
dimensional and meaningful way
• Morphing

Methodological principles
• Quantitative measurements
• Reliably measure threshold of individual
performance, not just group average
• Multiple comparison groups
www.abdn.ac.uk
The plan
• We would like to recruit people with BPD and
people who do not have BPD.
• We will compare performance on this task
before and after psychotherapy.
• Other tasks.
www.abdn.ac.uk
Outcome of this study
• Further understanding of mechanisms which
underpin BPD and psychotherapy
• What parts of the brain are different in BPD?
• How can we help understand what leads to the difficulties
experienced by people with BPD?
• Provide an explanation for BPD.
• How can we improve interventions?
• How can we aid identification of symptoms to ensure rapid
treatment?
www.abdn.ac.uk
Future research questions
• Psychophysiology
• Brain imaging
• Automated measures of face to face
interaction – outcome measures
