Culture

• Aim?


  To investigate whether people from different cultural backgrounds perceived depth cues in 2D images differently.
• Method?


  -Hudson showed 2D drawings to people in South Africa: native black people who were either schooled or unschooled and white people of European descent who were either schooled or unschooled

  -Ppts had to say which animal man was trying to spear

  -Spear was pointing at elephant and antelope but depth cues suggested it was actually being aimed at the antelope
• Results?


  -Despite the picture using HEIGHT IN THE VISUAL FIELD and RELATIVE SIZE to indicate depth many believed the spear was pointing to the elephant.

  -Both black and white schooled ppts were more likely to perceive depth than unschooled ppts

  -White schooled ppts were more likely to perceive depth than black schooled ppts
• Conclusion?


  People from different cultural and educational backgrounds have a different perceptual set and use depth cues differently.
• Weakness?


  -Instructions may not have made sense.

  -Language barrier means translation of method may have been unclear

  -This will therefore affect the validity of the results.
• Another weakness?


  -Some of the ppts may have been confused by seeing drawings on paper

  -When more familiar materials such as cloth were used different answers were given.

  -This shows representation affects results
• Strength?


  -Research conducted shows that African adults and children prefer the split style elephant.

  -It was concluded that perceiving perspective is a learned skill and influenced by culture which supports Hudson's research.
