ABSTRACT
Introduction. Inferential reasoning (IR) is a major component of intelligence, which comprises many different
cognitive processes such as perception, memory, and logic. Many studies have proposed that socioeconomic
status (SES) has a negligible association with IR, but more recent findings suggest that they may have a
higher association when evaluating group instead of individual SES.
Objective. The aim of this study is to test
the effects of both individual (students) and group (schools) socioeconomic status on IR, comparing different
countries of Latin America.
Method. The sample was composed of 2 358 students aged 14 and 15 years from
52 different schools (44% public) of five Latin American countries (Argentina, Brazil, Chile, Colombia, and
Peru). Participants took part in an inferential reasoning test and answered a socioeconomic questionnaire.
Results. SES student showed a small positive correlation with IR (
r = .10,
p ‹ .001), while SES school had a
more pronounced effect on IR (
F [2, 1944] = 74.68,
p ‹ .001, η
p2 = .07), with higher IR at schools with higher
SES. A significant difference of IR between countries (
F [4, 1976] = 20.68,
p ‹ .001, η
p2 = .04), was also found
with Peru showing the highest mean. Peru was the country with the higher percentage of private schools in
the present study. A multilevel model was fitted using individual and group SES as predictors.
Discussion
and conclusion. Our findings showed that group SES have a higher predictive value of IR when compared
to individual SES. This result suggests that individuals with low SES can benefit from studying on higher SES
schools. Future research and the importance of public policies are discussed.
