Study Notes

Experiment Overview

  • Conducted by Eleanor J. Gibson and Richard D. Walk in 1960.
  • Investigated depth perception abilities in newborn animals and human infants.

Research Hypothesis

  • Proposed that depth perception is an inherent ability, not learned.

Experiment Goals

  • Aimed to determine whether infants would crawl over an apparent cliff.
  • If infants crawled over, depth perception would be considered learned; if not, it supports the view that perceptual abilities are innate.

Variables

  • Independent Variable (Infants): Location where the infant was called (cliff side vs. shallow side).
  • Dependent Variable (Infants): Whether the child crawled to their mother.
  • Independent Variable (Animals): Different species of animals used in the study.
  • Dependent Variable (Animals): Preference for shallow or deep side of the visual apparatus cliff.

Sample Population

  • Included 36 infants aged 6 to 14 months.
  • Also included newborn animals (chicks, lambs, and young goats under 24 hours old).

Possible Confounding Factors

  • Sensory touch from a rat's whiskers could affect the results.

Ethical Concerns

  • Infants could experience distress when looking at the apparent drop or being encouraged to cross by their mothers, unaware of the safety measures (glass) in place.

Study Results

  • Concluded that depth perception is an innate ability.

Study Significance

  • Demonstrated that many human abilities, including depth perception, are inherent rather than solely learned, supporting the nativist perspective in psychology.
