drawings: Angles Drawn by Children

In louisaslett/durham-Rpkg: Durham University R Package

Description

The data come from an experiment on young children's drawing conducted by Dr. Charles Crook of the Psychology Department in Durham University.

Usage

data(drawings)

Format

A data frame with 36 rows and 23 columns:

[,1:7]	H30, ..., H150	numeric	Angles on horizontal baseline
[,8:14]	V30, ..., V150	numeric	Angles on vertical baseline
[,15:21]	O30, ..., O150	numeric	Angles on oblique baseline
[,22]	baseline	factor	Length of baseline (Long or Short)
[,23]	Child	factor	Number of child (1 to 36)

Details

Thirty-six five-year-olds each copied seven angles (30, 45, 60, 90, 120, 135 and 150 degrees) on to each of three pre-drawn baseline orientations: vertical, horizontal and 45 degrees (oblique). One group of 18 subjects drew on a long baseline and the remainder on a short baseline.

The data are, for each of the 36 children, the errors in each of the 21 angles drawn and a variable which indicates the baseline type. The error is positive, or negative respectively, if the angle is drawn closer to, or further from, the perpendicular than the target angle.

The experiment was motivated by previous research which demonstrated a tendency for children to make 45 degree angles approach the perpendicular except when drawn on a vertical baseline. Crook's experiment had a wider range of baselines and angles and hoped to generalise understanding of this tendency.
