“…Reaction Times and Accuracy were calculated based on the first key-press registered. Reaction time measurement started from stimulus offset, like in Verma and Brysbaert (2011). This means that 200 ms must be added to get the total processing time.…”

“…Apart from a vast array of clinical and neuroimaging research the hemispheric dominance for tool use has also been examined in behavioral studies. Verma & Brysbaert (2011) used the visual half-field (VHF) paradigm, in which stimuli are presented to the left and to the right of the fixation point and participants have to respond to the stimuli. The authors found that while there was no visual field difference for object recognition, a significant right visual field (RVF) advantage was observed for tools in the tool recognition task, in line with the left hemisphere dominance for tool processing.…”

“…Using tools and animals as target stimuli and identical or scrambled versions of the targets as primes, they reported that there was a RVF advantage in priming effects for tool targets but not for animal targets. Verma and Brysbaert (2011) argued that the strongest evidence for laterality of tool use in VHF studies is obtained when a tool recognition task is combined with an object recognition task. The prediction then is that a RVF advantage will be observed for tool recognition, together with no VHF advantage for object recognition.…”

“…A problem for the approach, however, was that it was impossible to find matched pictures of tools, non-tool objects and non-objects from the same database. As a result, Verma & Brysbaert (2011) had to compare pictures of tools vs. non-object tools from one source with pictures of objects vs. non-objects from another source. A similar problem was present in Garcea, Almedia, and Mahon (2012), who compared different sets of animals and tools as stimulus categories.…”

Neuropsychological and neuroimaging research has established that knowledge related to tool use and tool recognition is lateralized to the left cerebral hemisphere. Recently, behavioural studies with the visual half-field technique have confirmed the lateralization. A limitation of this research was that different sets of stimuli had to be used for the comparison of tools to other objects and objects to non-objects. Therefore, we developed a new set of stimuli containing matched triplets of tools, other objects and non-objects. With the new stimulus set, we successfully replicated the findings of no visual field advantage for objects in an object recognition task combined with a significant right visual field advantage for tools in a tool recognition task. The set of stimuli is available as supplemental data to this article

Attention is required for the perceptual integration of action object pairs

Previous studies have demonstrated that functionally related objects are perceptually grouped during visual identification if they are depicted as if interacting with each other (Green and Hummel in J Exp Psychol Hum Percept Perform 32(5):1107-1119, 2006). However, it is unclear whether this integration requires attention or occurs pre-attentively. Here, we used a divided-attention task with variable attentional load to address this question. Participants matched a word label to a target object that was immediately preceded by a briefly presented, task-irrelevant tool that was either functionally related or unrelated to the word label (e.g., axe | "log" or hammer | "log"). The tool was either positioned to interact with the target object or faced away from it. The amount of attention available to process the tool was manipulated by asking participants to make a concurrent perceptual discrimination of varying difficulty on a surrounding frame stimulus. The previously demonstrated advantage for the related-and-interacting condition was replicated under conditions of no or low attentional load. This benefit disappeared under high competing attentional load, indicating that attention is required to integrate functionally related objects together into a single perceptual unit.
