“…The modulation of the frontal and posterior N100 response to artifacts is consistent with previous studies that compared the effect of animals and artifacts in visual categorization (Antal et al, 2000(Antal et al, , 2001Proverbio et al, 2007). Furthermore, our posterior N100, peaking around 200 ms, resembles the negative deflection over occipito-temporal areas (N200 or N150) reflecting selective attention effects in target decision tasks using animals (Codispoti et al, 2006;Johnson and Olshausen, 2003) and objects (Van Rullen and Thorpe, 2001). The N150 has been considered to reflect perceptual selection mechanisms devoted to high level features extraction (as those selected in visual categorization) (Codispoti et al, 2006) and, more importantly, it has been demonstrated not to be dependent on low level sensory analysis (Van Rullen and Thorpe, 2001).…”

“…The concept of attractiveness for tools, instead of esthetic or beauty, is used here in order to underline the subjective emotional attraction and desirability for tools. We use the concept of "action affordance" (Proverbio et al, 2011) which means the subjective perceived degree of motoric associations related to the knowledge of learned motor representations that enable the correct use of familiar tools (Valyear et al, 2007). In this vein, the evaluation of "high affording" is given when subjects immediately and automatically are able to evoke the motor responses associated to the visually presented tools.…”

The relation between attractiveness and motor affordance is a key topic in design and has not yet been investigated electrophysiologically. In this respect, action affordance and attractiveness represent two crucial dimensions in object processing (specifically for tools). In light of this evidence, Event Related Potentials (ERPs) enabled us to gain new insights into the time course of the interaction between these two dimensions during an explicit tool evaluation task. Behaviorally, tools that were judged as high affording and high attractive yielded faster response times than those judged as low affording and low attractive. The ERP results showed that early processes related to sensory gating and feature extraction (N100) were sensitive to both affordance and attractiveness; the P200 was dominated by affordance, indexing a facilitated access to motor action representation. The N300, P300 and the Late Positive Potential (LPP) showed enhanced responses for highly affording/attractive tools, reflecting the interconnection between attractiveness and affordance. Later responses were entirely affected by attractiveness, suggesting additional affective responses evoked by desirable tools. We are showing that things that are perceived as more functional and attractive have a privileged neural activation in the time course of tool evaluation, for the first time.

“…For example, the danger posed by an animal is not necessarily size-related, nor is the task of inferring intentions and goals. On this functional account, cortical organization may be driven by distinct long-range connections to downstream processes (Mahon and Caramazza, 2011), for example, connecting big object zones to navigational networks (Epstein, 2008), small object zones to dorsal stream reaching regions (Valyear et al, 2007;Bracci et al, 2012), and animate zones to goal-inference or other social regions (Caramazza and Shelton, 1998;Frith, 2007). Alternatively, one could interpret these divisions in terms of the statistical structure in visual/shape properties of these categories.…”

Occipito-temporal cortex is known to house visual object representations, but the organization of the neural activation patterns along this cortex is still being discovered. Here we found a systematic, large-scale structure in the neural responses related to the interaction between two major cognitive dimensions of object representation: animacy and real-world size. Neural responses were measured with functional magnetic resonance imaging while human observers viewed images of big and small animals and big and small objects. We found that real-world size drives differential responses only in the object domain, not the animate domain, yielding a tripartite distinction in the space of object representation. Specifically, cortical zones with distinct response preferences for big objects, all animals, and small objects, are arranged in a spoked organization around the occipital pole, along a single ventromedial, to lateral, to dorsomedial axis. The preference zones are duplicated on the ventral and lateral surface of the brain. Such a duplication indicates that a yet unknown higherorder division of labor separates object processing into two substreams of the ventral visual pathway. Broadly, we suggest that these large-scale neural divisions reflect the major joints in the representational structure of objects and thus place informative constraints on the nature of the underlying cognitive architecture.

“…Simply viewing pictures of tools was found to activate left parietofrontal areas putatively important for actual tool use (Chao and Martin, 2000;Valyear et al, 2007) and to affect response times to initiate real actions according to affordances defined by both structural and functional tool properties (Bub et al, 2003;Bub et al, 2008). More recently, it was shown that affordance specification for tools includes information about predicted outcomes of actions in accordance with their conventional use (Masson et al, 2011), and reaction times to pantomime tool use with tools in hand are facilitated when preceded by passive viewing of real tools .…”

fMRI Repetition Suppression for Familiar But Not Arbitrary Actions with Tools

et al. 2012

For humans, daily life is characterized by routine interaction with many different tools for which corresponding actions are specified and performed according to well-learned procedures. The current study used functional MRI (fMRI) repetition suppression (RS) to identify brain areas underlying the transformation of visually defined tool properties to corresponding motor programs for conventional use. Before grasping and demonstrating how to use a specific tool, participants passively viewed either the same (repeated) tool or a different (non-repeated) tool. Repetition of tools led to reduced fMRI signals (RS) within a selective network of parietal and premotor areas. Comparison with newly learned, arbitrarily defined control actions revealed specificity of RS for tool use, thought to reflect differences in the extent of previous sensorimotor experience. The findings indicate that familiar tools are visually represented within the same sensorimotor areas underlying their dexterous use according to learned properties defined by previous experience. This interpretation resonates with the broader concept of affordance specification considered fundamental to action planning and execution whereby action-relevant object properties (affordances) are visually represented in sensorimotor areas. The current findings extend this view to reveal that affordance specification in humans includes learned object properties defined by previous sensorimotor experience. From an evolutionary perspective, the neural mechanisms identified in the current study offer clear survival advantage, providing fast efficient transformation of visual information to appropriate motor responses based on previous experience.
