What do children’s drawings tell us about child development?
Learning objectives • Outline & explain the Stage theory of drawing development. • Discuss evidence for and against the idea of a stage theory of drawing development. • Discuss alternative explanations for the exceptional artistic ability found in some autistic savants. • Describe the developmental differences which occur when children with typical development are asked to modify their drawings in accordance with new goals. • Discuss and critically evaluate Karmilioff-Smith’s account of representational redescription in relation to children’s drawing development. Cite evidence for and against this theory.
Why should we study children’s drawings? - Learn about acquisition of drawing skills such as: motor execution, planning strategies, spatio-geometric and part-whole relations, and artistic talent. -To use it as a source of evidence with respect to more general processes such as representational change.
How can we study children’s drawings?Two approaches (Vinter, 1999) • Product oriented approach- The “what” of drawing or the trace left on the paper. • Process oriented approach – The “how” of drawing or the organisation of movement used for drawing.
How does drawing develop? • Are there coherent characteristics of each stage? • Is each stage qualitatively different then the next? • Are the transitions between stages rapid? • Is there a fixed order in which stages progress? • Are stages Universal? • If you can answer YES to all the above then development is stage like.
Drawing develops through distinct stages(Luquet, 1913;1927; Piaget & Inhelder 1956;1971) 1.) Scribbling (ages 2-4)- fortuitous realism 2.) Preschematic stage (ages 4-7) Failed realism– elements are unrelated/unconnected Intellectual realism – Children draw what they “know” 3.) Schematic stage (ages 8-9) Visual realism – children draw what they “see”
What influences children’s drawing?(Luquet) • Child’s internal model/representation (mental image) - Contains the critical features of that topic (sides of cube). - Attempt to include all critical features may result in unrealistic drawing. (sides of cube drawn folded out or cup with handle)
Visual & Intellectual realism (Freeman & Janikoun, 1972) • Intellectual realism- draw what you know rather than what you see • Visual realism-draw what you see in a very realistic way
Visual & Intellectual realism Cox (1978,1981) Occlusion task- Children younger than 8 yrs. Failed to draw the appropriate relationship. incorrect correct
Luquet / Piaget &Inhelder (1956,1969) • Luquet’s theory of drawings as representations of internal models has been taken up as a cognitive theory (Piaget incorporated ideas into his own account of child dev.) , even though…… • Luquet does acknowledge other influencing factors which include non-cognitive factors. Thus, it is doubtful that Luquet was a strong advocate of stages.
Criticisms of stage account(see intro in Charman & Baron-Cohen,1993) • Stages too rigid (Freeman, 1980) • 6yr olds more successful in drawing occluded objects when meaningful context added (Cox,1981) • When balls given faces children aged 7 were able to give a partial occlusion response. (Littleton & Cox, 1989)
Are there developmental stages?(see intro in Charman & Baron-Cohen,1993) • The idea of rigid stages has been left behind, however children still show evidence of sequential cummulative progression in drawing development. • Despite an abundance of literature challenging stages account of drawing, children below age 5 rarely produce visually real drawings (Shift from intellectual to realistic drawing still occurs in young children)
Do individuals with autism progress through drawing stages more rapidly? (Eames & Cox,1994; Charman & Baron-Cohen, 1993) • Those in the general autistic population? Found: No evidence that those with autism progress more rapidly to visual realism. Conclude: Those with autism produce intellectually realistic drawings, like those with typical development. This means they have the capacity to represent non-mental representations (using their internal model).
But how can we explain autistic savants? • Perhaps those with savant abilities form representational schemas as those with typical development, but features emphasized are primarily structural descriptions rather than semantic knowledge.
Pring & Hermelin, 1993 • Aimed to investigate the mental processes contributing to graphic aptitude of savant artists. • Does reproduction memory and picture sorting rely on structural or semantic features in savant and non-savant artists?
Conclusions • There is no evidence to suggest that autistic savants have a particularly well developed memory for the visual-structural features of objects, or have overall more efficient visual memory.
Snyder & Thomas (1997) • Argue autistic artists make no assumptions about what is seen in their environment. • They do not have mental representations about what is salient in their environment and see all details as equally important. • Perhaps perception is less Top-down
Why study children’s drawings? 1.) Explore acquisition of drawing skills such as: motor execution, planning strategies, spatio-geometric and part-whole relations, and artistic talent). 2.) To use it as a source of evidence with respect to more general processes such as representational change.
Representational change • Knowledge is internalised and stored in the form of symbolic representations in a person’s mind. • These internal representations may be modified to integrate new information.
Karmiloff-Smith (1990;1992) • First attempt to combine the Nativist and Piagetian views of cognitive development. • Infants are born with specified pre-dispositions or biases that focus attention to relevant environmental inputs. • Initial representations become redescribed/reformatted with experience.
Constraints theory of child development • An internal representation is first specified as a sequentially fixed list. (constraints exists at this level). • Through representational redescription sequential constraints are relaxed. • End result is an internal representation which is specified as a structured yet easily manipulable set of features.
Karmiloff-Smith (1990) • Children were asked to draw a man with 2 heads • They found 5 year olds were significantly less successful than 8 years olds.
Alternative explanations • Zhi, Thomas, and Robinson (1997) argue that Karmiloff-Smith’s findings may be result of: 1.) Small sample size 2.) Motivational/Dispositional factors 3.) Attentional factors
Experiment 1 Aim to replicate with larger sample • 32 (4-5 year olds); 26 (8-10 year olds) • Half of children were shown a picture of a woman with 2 heads before drawing.
Experiment 2 Aim to explore dispositional factors • 26 (4-5 year olds) Unfamiliar object
Experiment 3 Aimed to explore whether inflexibility in drawing could be found in younger children. • 32 (3-4 year olds)
Experiment 4 • Aimed to explore external task –related factors, such as attention. • 81 (3-5 year olds)
Summary of supporting evidence • A substantial number of 4-5 year olds failed even with the clarification of seeing the illustration first and a larger sample size. • Study 2 ruled out dispositional factors • Study 4 ruled out attentional factors
Challenges to theory • Many 3-4 year olds could successfully adapt their usual drawing procedure to produce a man with 2 heads. • External factors such as trying to maintain a coherent and symmetrical composition may be able to account for difficulties with drawing a two headed figure.
