Modulating perceptual learning: Anodal transcranial Direct Current Stimulation (tDCS) reduces the Face Inversion Effect (FIE), while cathodal restores it to baseline

Key Points

• Anodal transcranial direct current stimulation significantly reduces the face inversion effect, enhancing facial recognition.
• The observed reduction in the face inversion effect was accompanied by a noticeable improvement in recognition accuracy.
• Assessment using transcranial direct current stimulation revealed distinct impacts of anodal and cathodal techniques on perceptual learning.
• This study highlights the potential for tDCS to alter perceptual processing, but further exploration is necessary to validate findings.
