Questions and Answers
What is the specificity account of face recognition and how does it differ from the expertise account?
What is the specificity account of face recognition and how does it differ from the expertise account?
The specificity account suggests that faces are recognized differently than other stimuli, while the expertise account suggests that familiarity with a stimulus configuration leads to robust inversion effects.
How does fMRI detect brain activity?
How does fMRI detect brain activity?
fMRI detects brain activity by changes in oxygen levels in the blood.
What is the Face Fusiform Area (FFA)?

Study Notes
- The specificity account suggests that faces are recognized differently than other stimuli.
- The expertise account suggests that familiarity with a stimulus configuration leads to robust inversion effects.
- fMRI detects brain activity by changes in oxygen levels in the blood.
- The Face Fusiform Area (FFA) is a cortical region that is more activated when presented with faces.
- EEG measures electrical activity generated by synchronized activity of neurons.
- ERPs are small voltages generated in response to specific stimuli.
- The N170 component shows a larger inversion effect for faces compared to other stimuli.
- tDCS is a brain stimulation technique that can reduce the inversion effect for faces.
- tDCS can be applied during a face matching task to study prosopagnosia.
- The expertise account suggests that familiarity with a stimulus configuration leads to robust inversion effects for all stimuli.
- The study investigates the processes involved in face recognition using tDCS.
- Participants must be 18 or older, right-handed, and generally healthy.
- The tDCS technique involves the application of a weak current via two electrodes on the head.
- The stimulation feels slightly warm and tingly.
- The study takes about 45 minutes and participants receive £7 or 1 credit.
- The tDCS procedure eliminates the checkerboard inversion effect index of expertise.
- It reduces significantly the face inversion effect indicating that a component of it is based on expertise.
- The remaining face inversion effect could be due to specificity.
- The study references several previous studies on perceptual learning and face recognition.
- The main reference is Civile et al. (2021) published in Scientific Reports.
