Measuring Emotions and Emotional Regulation in Patients with Focal Lesions (4b) Flashcards
focal lesions
damage to the brain that can be measured and has very specific area of damage
traumatic brain injury (TBI)
may not be considered as a focal lesion, as there might be a possibility of diffusional damage
causes of focal lesions
- stroke
- brain aneurysm
- brain haemorrhage
- brain tumour resection
- carbon monoxide poisoning
- encephalitis
- hydrocephalus
- hypoxic/ anoxic
- meningitis
when does a stroke occur
when the brain’s blood flow is blocked (87%) and bleeds (13%)
emotion in brain injury
- brain injury can often bring about changes in emotions/ emotional regulation
- depression/ anxiety might be linked to brain injury
- frontal damage can affect the ability to regulate one’s emotions
- may be even reduced ability to inhibit
- affected by cognitive flexibility
VLSM steps
- draw lesion
- normalise brains
- compute statistics
- threshold statistics
- visualise
what is lesion analysis
- mapping area of damage using a software
- MRIcron is most often used
- correlation or regression
advantages of lesion mapping
- stronger interface
- understand function of tightly couples network
- clinically relevant
problems with overlay plots
- misleading (highlight areas involved with task and areas commonly damaged)
- brain damage is not random - overlay plots highlights these areas of common damage
what can statistical plots be used for
to identify areas that reliably predict deficit
affect rating dial
- measure emotions in people with lesions
- continuous measure
- easier to indicate rapid changes
- allows researchers to collect online emotion ratings
facial action coding system (FACS)
- comprehensive, anatomically based system for describing visually discernible facial movement
- breaks down facial expressions into individual components of muscle movement (action units)
social cognition and emotional assessment
- use the stimuli and ask them to respond
- show how to calculate score
assessing emotions in rehabilitation
- hospital anxiety and depression scale (Zigmond & Snaith, 1983) = sensitive tool to capture symptoms in acquired brain injury population
- the emotion regulation scale (Gross & John, 2003) = good to capture the use of suppression or reappraisal
- PANAS (Watson & Clark, 1994) = positive and negative affect schedule
emotional processing scale (EPS)
25-item questionnaire designed to identify emotional processing styles and potential deficits
