BlackTom AI · Accepted Answer

Parents' implicit gender bias is likely a major source of gender stereotypes that children develop.

1) Relevant knowledge points and concepts
- Implicit bias: automatic, often unconscious attitudes or stereotypes that influence judgments and behavior.
- Social learning: children learn gender norms from caregivers’ expectations and feedback.
- Experimental design in developmental psychology: compare caregivers’ estimates of infants’ abilities to infants’ actual performance to reveal biases.

2) Step-by-step reasoning process
- Mondschein et al. (2000) asked mothers to estimate how steep a slope their baby could crawl down safely (an angle judgment) and then observed the infants’ actual performance on the slope task.
- If mothers’ estimates differed by the infant’s gender while infants’ actual crawling ability did not, that would indicate mothers’ expectations were influenced by gender, not by real physical differences.
- The study found a systematic difference: mothers expected boys to manage steeper slopes than girls, even though boys and girls performed similarly in reality. This pattern reflects an implicit bias in mothers’ expectations.

3) Calculations / intermediate steps
- The essential “calculation” is the comparison: Estimated safe slope for boys versus girls minus Observed maximum slope for boys versus girls.
- Mondschein et al. reported that mothers’ estimates favored boys by roughly the same magnitude that they underestimated girls (commonly reported as about a 9° difference in estimates), whereas infants’ actual abilities did not show a gender gap. This difference (estimated minus actual) reveals bias.

4) Why the correct answer is correct
- Because mothers’ judgments differed by infant gender despite no physical ability difference, the best interpretation is that parents hold implicit gender-based expectations. Those expectations are transmitted to children and can form foundations for later gender stereotypes.

5) Why the other options are incorrect
- Option A (specific under/overestimation by 9°) is a narrow numerical statement rather than the broader lesson about bias; it also mixes directionality in a way that can misrepresent the study’s main implication.
- Option C (expectations based on physical differences) is incorrect because the infants’ actual crawling ability did not differ by gender, so physical differences do not explain mothers’ different expectations.
- Option D (mothers underestimated daughters but accurately estimated sons) is inaccurate: mothers’ expectations were biased for both sexes relative to objective performance, favoring boys.

6) Conclusion
The study demonstrates that parents’ implicit gender bias shapes expectations about infants’ abilities, supporting the provided answer: Parents' implicit gender bias is likely a major source of gender stereotypes that children develop.
