Beck, Sarah R.; Apperly, Ian A.; Chappell, Jackie; Guthrie, Carlie; Cutting, Nicola – Cognition, 2011
Tool making evidences intelligent, flexible thinking. In Experiment 1, we confirmed that 4- to 7-year-olds chose a hook tool to retrieve a bucket from a tube. In Experiment 2, 3- to 5-year-olds consistently failed to innovate a simple hook tool. Eight-year-olds performed at mature levels. In contrast, making a tool following demonstration was easy…

Girardi, Giovanna; Lindemann, Oliver; Bekkering, Harold – Journal of Experimental Psychology: Human Perception and Performance, 2010
In 4 experiments, we investigated the effects of object affordance in reach-to-grasp actions. Participants indicated whether a depicted small or large object was natural or manmade by means of different object-grasping responses (i.e., with a power or a precision grip). We observed that the size of the depicted object affected the grasping…

Chu, Mingyuan; Kita, Sotaro – Journal of Experimental Psychology: General, 2008
This study investigated the motor strategy involved in mental rotation tasks by examining 2 types of spontaneous gestures (hand-object interaction gestures, representing the agentive hand action on an object, vs. object-movement gestures, representing the movement of an object by itself) and different types of verbal descriptions of rotation.…

Fajen, Brett R. – Journal of Experimental Psychology: Human Perception and Performance, 2005
Braking to avoid a collision can be controlled by keeping the deceleration required to stop (i.e., ideal deceleration) in the "safe" region below maximum deceleration, but maximum deceleration is not optically specified and can vary as conditions change. When brake strength was manipulated between participants using a simulated braking task, the…
