Weight lifting judgment in children

Description

Humans are able to estimate the weight of an object by watching how another person interacts with the object. Eighty subjects of various ages were asked to estimate the weight of objects of various weights after watching a video of an actor interacting with the weights.

Usage

weight_estimate

Format

A data frame with 80 observations of 7 variables

id

ID

height

Height of subject in cm.

mean100

Mean of estimated weight for objects that weighed 100 g.

mean200

Mean of estimated weight for objects that weighed 200 g.

mean300

Mean of estimated weight for objects that weighed 300 g.

mean400

Mean of estimated weight for objects that weighed 400 g.

age

Age group that the subject is in. Factor with levels 6, 8, 10 and adult.

Details

From the authors: "Humans are excellent at perceiving different features of the actions performed by others. For instance, by viewing someone else manipulating an unknown object, one can infer its weight–an intrinsic feature otherwise not directly accessible through vision. How such perceptual skill develops during childhood remains unclear."
