TL;DR
The authors found that holistic-configural effects can arise from object representations that are differentiated in terms of features or parts, and found that a holistic-inclusive effect was correlated with changes in the right FFA.
Abstract
Behavioral sensitivity to object transformations and the response to novel objects (Greebles) in the fusiform face area (FFA) was measured several times during expertise training. Sensitivity to 3 transformations increased with expertise: (a) configural changes in which halves of objects were misaligned, (b) configural changes in which some of the object parts were moved, and (c) the substitution of an object part with a part from a different object. The authors found that holistic-configural effects can arise from object representations that are differentiated in terms of features or parts. Moreover, a holistic-inclusive effect was correlated with changes in the right FFA. Face recognition may not be unique in its reliance on holistic processing, measured in terms of both behavior and brain activation.

It is concluded that face recognition normally depends on two systems: a holistic, face-specific system that is dependent on orientationspecific coding of second-order relational features (internal) and a part-based object-recognition system, which is damaged in CK and which contributes to face recognition when the face stimulus does not satisfy the domain-specific conditions needed to activate the face system.

Despite many differences, theories of object recognition include some common principles, including the decomposition of an image into component features, the coding of the spatial relations between such features, multiple views to represent feature sets arising from different object viewpoints, generalization mechanisms to normalize over changes in viewing conditions, and the flexibility to support recognition tasks ranging from item-specific individuation to basic-level categorization.
