Expertise effects for nonface objects in face-selective brain areas may reflect stable aspects of neuronal selectivity that determine how observers perceive objects. However, bottom-up (e.g., clutter from irrelevant objects) and top-down manipulations attentional selection) can influence activity, affecting the link between category individual performance. We test prediction differences expressed as neural expertise cars are sufficiently to survive attention. Additionally, behavioral work...

Facial caricatures exaggerate the distinctive features of a face and may elevate recognition familiar face. We investigate whether facial composites, or pictures criminal faces, could be similarly enhanced. In this study, participants first estimated degree caricature necessary to make composites most identifiable. Contrary expectation, an anticaricature was found best, presumably as tended reduce appearance errors. support explanation, more positive estimates were assigned morphed...

Inversion disproportionately impairs recognition of face stimuli compared to nonface arguably due the holistic manner in which faces are processed. A qualification is put forward first point fixated on different for upright and inverted this carries some face-inversion effect. Three experiments explored possibility by using fixation crosses guide attention eye or mouth region to-be-presented orientations. Recognition was better when cross appeared at than region. The effect smaller eyes were...

The hippocampus is considered pivotal to recall, allowing retrieval of information not available in the immediate environment. In contrast, neocortex thought signal familiarity, contributing recall only when called upon by hippocampus. However, this view compatible with representational accounts memory, which reject mapping cognitive processes onto brain regions. According accounts, engaged per se, rather it whenever hippocampal representations are required. To test whether required, we used...

Summary The persistence of parasites that are only seen in intermittent outbreaks has intrigued ecologists. Long the subject speculation, there is now evidence viral insect diseases can cause covert as well overt infections. Typically, infection leads to overtly diseased individuals infectious and die a result disease, but it also produce other show covert, non‐infectious pathology, which typically asymptomatic. Covertly infected do not infection, although they may be affected sublethally...

Holistic processing is a hallmark of face processing. There evidence that holistic strongest for faces at identification distance 2–10 metres from the observer. However, this based on tasks have been little used in literature and are indirect measures We use composite task—a well validated frequently paradigm—to measure effect viewing In line with previous work, we find congruency x alignment close (2 m equivalent distance) than further away (24 distance). contrast, same trials, by several...

Visual object expertise correlates with neural selectivity in the fusiform face area (FFA). Although behavioral studies suggest that visual is associated increased use of holistic and configural information, little known about nature supporting representations. Using high-resolution 7-T functional magnetic resonance imaging, we recorded multivoxel activation patterns elicited by whole cars, configurally disrupted car parts individuals a wide range expertise. A probabilistic support vector...

Facial composites are pictures of human faces.These normally constructed by victims and witnesses crime who describe a suspect's face then select individual facial features.Unfortunately, research has shown that in this way not often recognised.In contrast, we quite good at recognizing complete faces, even if the is unfamiliar only seen briefly.This more natural processing faces heart new composite system called EvoFIT.With computer program, presented with sets for selection 'evolved' over...

Abstract Eyewitnesses often construct a "composite" face of person they saw commit crime, picture that police use to identify suspects. We described technique (Frowd, Bruce, Ross, McIntyre, & Hancock, 2007) based on facial caricature facilitate recognition these images: Correct naming substantially improves when composites are seen with progressive positive caricature, where distinctive information is enhanced, and then negative the opposite. Over course four experiments, underpinnings this...

The Vanderbilt Holistic Face Processing Test (VHPT-F) is a new measure of holistic face processing with better psychometric properties relative to prior measures developed for group studies (Richler et al., 2014). In fields where psychologists study individual differences, validation are commonplace and the concurrent validity established by comparing it an older validity. We follow this approach test whether VHPT-F same construct as composite task, which group-based at center large...

Recent research has provided evidence for the role of norm-based coding in face recognition (e.g., Leopold et al., 2001). In such a model, any given can be represented by vector from norm, with difference between two faces being vectors. However, as previously been suggested it is also possible to conceive model which angle vectors provides relevant information differentiating faces. Two experiments investigated this possibility using matching paradigm. Discrimination was found better when...

Studying individual differences requires measures with sufficient reliability, often ignored in high-level vision. Holistic processing is central to research on face recognition and, more recently, the study of this area. A popular measure holistic processing, composite task, highly sensitive group studies (Richler & Gauthier, 2014), but shows low reliability (~.2; DeGutis et al., 2013; Ross 2014). We present a Vanderbilt Face Processing Test (VHPT-F), specifically designed for research. As...

Face adaptation is widely used as a means to probe the neural representations that support face recognition. While theories relate behavioral aftereffects may seem conceptually simple, our work has shown testing computational instantiations of these can lead unexpected results. Instantiating model not only requires specifying how faces are represented and shapes those but also decisions made, translating hidden representational states into observed responses. Considering high-dimensionality...

Perceptual expertise with an object category correlates increased neural selectivity to that in several visual areas, the most robust effects fusiform face area (FFA). While FFA are well established, little is known about representations underlie these effects. Prior work training studies novel objects found acquired behavioral holistic processing correlated FFA. Here, we probe of cars for evidence information as a function car expertise. With high-resolution 7T fMRI, sample 26 participants,...

We examined the effect of perceptual experience on visual representations in human cortex. Perirhinal cortex lies at anterior end ventral stream and is thought to store complex whole objects. One theory perirhinal function claims that it important for discriminating highly similar objects share simple features, there evidence support this claim. However, not known how shapes influences object short-term (i.e., seeing many from same category over course a few minutes) throughout Participants...
