Developing an ability to draw Flashcards
Goodnow (1977)
Children draw people as tadpole (head and legs) without any instruction
Luquet (1920s): intellectual realism
Drawings are often influenced by what we know rather than what we can see (car with 4 wheels even though only 2 are visible)
Piaget and Inhelder (1967): reason for IR and criticism of this view
Egocentrism: unable to recognise multiple perspectives
Consequence of trying to portray important features?
Freeman and Janikoun (1972)
Defining features
Under 7s ommitted the flower but included the handle (over 7s did the opposite)
- Defining feature
Bremner and Moore (1984)
Role of knowledge
5-7 yr olds in two groups: mug with handle and mug without
Only those that saw the handle included it in their drawings
Knowledge of the identity of the object influenced drawings
Crook (1984)
Opaque or transparent
Rod through the ball: children drew the rod all the way through the ball visually - displayed hidden detail
Roads pushed either side into the ball: child draw the roads either side of the ball
Light and Humphreys (1981)
Partial occulsion
5-6yr olds had to draw two pigs (one behind the other) from 4 sides of the table
They always drew the pigs side by side
No occulsion but maintained spatial relations
Light and MacIntosh (1980)
Depicting spatial relations Draw glass with house behind it - Drew glass with house beside it Draw glass with house inside it - Drew glass with house inside it
Davis (1983)
Spatial relations
Two cups, one with handle out of view
4-6yr olds drew both cups without a handle
Included the handle when asked to draw the cup with the handle ommitted
Spatial relations more important that object identity
Light and Simmons (1983)
Communiate information
Red and blue ball side by side and each child has to draw the balls so that the next child would know where they were sitting
6yr olds always drew balls side by side
- Even when they knew this didn’t communicate a useful message
Reith and Dominin (1997)
5 and 9 year olds tested on da Vinci window where one ball partially excludes the other
Some 8-9yr olds show IR by selecting two balls, not a crescent against a circle, to represent what they see
Do adults have IR? Tracing and line drawings
Adults were influenced by what they thought it should look like
Not poor motor skills: better when tracing
Not poor representational decisions: errors on line drawings
Mitchell, Ropar, Ackroyd, Rajendran (2005): shepard illusion
Increased level of misperception from the tables
Stored info about the appearances of this kind of object
Mitchell et al. (2005)
Draw both versions of shepard illusion with strong or weak 3D cues
- More errors with 3D cues
- Knowledge contaminated ability to draw accurately
Shepard et al. (2005)
Meaningful and non-meaningful 3D and 2D stimuli composed of same lines
7yr olds made more errors drawing 3D than 2D
More accurate with meaningful than non-meaningful
Drawings distorted to viewer’s knowledge
