Our understanding of human tool use comes mainly from neuropsychology, particularly from
patients with apraxia or action disorganization syndrome. However, there is no integrative …

Log-polar imaging consists of a type of methods that represent visual information with a
space-variant resolution inspired by the visual system of mammals. It has been studied for …

Tool use is a defining feature of human species. Therefore, a fundamental issue is to
understand the cognitive bases of human tool use. Given that people cannot use tools …

Although regions within the medial frontal cortex are known to be active during voluntary
movements their precise role remains unclear. Here we combine functional imaging …

It is well known that specific components of motor programs are automatically activated
when they are afforded by object related pragmatic features. Among these features the …

Reaction time is often shorter when the irrelevant graspable handle of an object
corresponds with the location of a keypress response to the relevant attribute than when it …

Five experiments systematically investigated whether orientation is a visual object property
that affords action. The primary aim was to establish the existence of a pure physical …

In the present study two separate stimulus–response compatibility effects (functional
affordance and Simon-like effects) were investigated with centrally presented pictures of an …

How do humans interact with tools? Gibson (1979) suggested that humans perceive directly
what tools afford in terms of meaningful actions. This “affordances” hypothesis implies that …

Conventionally, voluntary conscious acts and automatic behavior have been considered to
be mediated by separate processes—and by separate brain structures. In this review, the …
