Jr. Mcgahan et al., HEIGHT, WEIGHT, AND BODY-FAT - ASSESSMENTS OF COVARIATION BASED ON VISUAL, INFORMATION OR REPORTED CORRELATIONS, Perceptual and motor skills, 86(1), 1998, pp. 99-110
College students' intuitive judgments about covariations between heigh
t, weight, and body fat were assessed in three experiments using respo
nses to a series of propositional statements as the dependent variable
. In Exp. 1, judgments were rendered without explicit exposure to a pr
ior database. In Exps. 2 and 3, however, databases were studied prior
to these judgments. Remarkable consistencies in judgments of weight an
d body far, height and weight as well as of height and body far were o
btained across experiments. At best, there was little evidence that th
e databases influenced the judged covariations among these variables.
Whereas judgments about weight and body fat were unambiguous and consi
stent with the actual positive correlation between weight and body fat
, judgments about height and weight as well as height and body fat wer
e less clearcut. What was clear, however, was that these judgements we
re highly similar. Implications of these findings from previous resear
ch :hat suggest the presence of a perceived negative correlation betwe
en height and body fat are discussed.
