Perceptual learning is a key perceptual skill that people possess, in particular, it contributes to their ability to distinguish between faces thus recognize individuals. Recently, we showed that anodal transcranial Direct Current Stimulation (tDCS) at Fp3 abolishes the inversion effect (that would otherwise exist) for familiar checkerboards created from a prototype. Because of the close analogy between the inversion effect obtained with checkerboards, which we use as a marker for perceptual…

Switching off perceptual learning: Anodal transcranial direct current stimulation (tDCS) at Fp3 eliminates perceptual learning in humans.
TLDR
It is shown that anodal transcranial Direct Current Stimulation at Fp3 directly influences this modulation process so as to eliminate and possibly reverse perceptual learning and opens up the possibility of controlling this phenomenon.
Electrical Stimulation over Bilateral Occipito-Temporal Regions Reduces N170 in the Right Hemisphere and the Composite Face Effect
TLDR
The present study demonstrates that N170 can be causally manipulated by stimulating the OT with weak currents, and provides evidence that obligatory attention to all parts of a face can be affected by the commonly used tDCS parameter setting.
Perceptual learning and inversion effects: Recognition of prototype-defined familiar checkerboards.
TLDR
A theory of perceptual learning originally proposed by McLaren, Kaye, and Mackintosh (1989) with explanations of the face inversion effect, first reported by Yin are integrated.

TLDR
It would be remarkable if the inversion effects demonstrated with the abstract categories used in the experiments reported here were not implicated in the inversions effects found with other classes of stimuli, whilst conceding that the analogy is not complete, particularly in the case of faces.
Why faces are and are not special: an effect of expertise.
TLDR
Three experiments show that for dog experts sufficiently knowledgeable to individuate dogs of the same breed, memory for photographs of dogs of that breed is as disrupted by inversion as is face recognition, consistent with the view that experts represent items in memory in terms of distinguishing features of a different kind than do novices.
The Face Inversion Effect—Parts and Wholes: Individual Features and Their Configuration
TLDR
The results for scrambled faces are consistent with an account that has recognition performance entirely determined by the proportion of upright facial features within a stimulus, and that any ability to make use of the spatial configuration of these features seems to benefit upright and inverted normal faces alike.
The Face Inversion Effect: Roles of First- and Second-Order Configural Information.
TLDR
This article tests whether there is a role for configural information in producing the FIE and whether second- or first-order relational information is particularly important and establishes that both local feature orientation and first- order relational information have a role in determining theFIE.
Perceptual learning for a familiar category under inversion: An analogue of face inversion?
TLDR
The results showed that familiarity with a category defined by a prototype gave subjects an enhanced ability to discriminate between exemplars of that category in an upright orientation, to the extent that learning of the discrimination involving inverted familiar exemplars was worse than for appropriate controls.
