We conducted three preregistered studies using the Organization for Economic Co-operation and Development Programme for International Student Assessment (PISA) data to provide a worldwide estimation of the standardized test gap between students from lower and higher social classes. We investigated: (a) the degree to which academic anxiety…

Recent research has documented the academic disadvantage of low social class students, whose performance is impaired by competitive educational practices. Across 2 experiments, we examined whether the pursuit of performance-approach goals (aiming to outperform others) favors the emergence of this achievement gap. We first manipulated low versus…

To understand the persistent social class achievement gap, researchers have investigated how educational settings affect lower versus higher socioeconomic status (SES) students' performance. We move beyond the question of actual performance to study its assessment by evaluators. We hypothesized that even in the absence of performance differences,…

In this paper, we develop an information distortion model (IDM) of social class differences in self-beliefs and values. The IDM combines psychological biases on frame-of-reference effects with sociological foci on ability stratification. This combination is hypothesized to lead to working-class children having more positive math self-beliefs and…

A large body of research has demonstrated a big-fish--little-pond effect (BFLPE) by showing that equally able students have lower academic self-concepts in high-ability schools than in low-ability schools. Although the BFLPE generalizes across many countries, it varies significantly between countries. The reasons for this variation are still…

The major finding of this study is that there is a larger socioeconomic status or Negro-White difference on intelligence measures than on measures of rote learning and memory. The difference in the performance of Negro and White children increases with age. (EH)

A sample of 201 high school students was given a battery of 27 ability tests strategically chosen to provide composite measures of 12 primary mental abilities selected to indicate second-order abilities known as fluid intelligence (Gf), crystallized intelligence (Gc), and short-term acquisition retrieval (SAR). (Author/GK)

Although there were social class and race differences in achievement and intelligence test scores, no relationship was found between attending and these variables. There was a significant correlation between the intelligence and achievement test scores, but no evidence that the relationship was different for the different groups. (Author/MV)

Six hundred boys divided by age (6-8), race (black and white) and social class (middle and lower) were given tests for memory, intelligence, learning, and transfer. Findings indicated social class differences on learning and intelligence tests, with racial differences on intelligence, digit span, and paired-associate learning. (Author/MV)

The self-enhancement model (that perceived evaluations of others cause self-evaluation of ability, which in turn causes academic achievement) was not supported. However, among females, academic achievement caused both self- and other-evaluations as well as aspirations. The causal patterns did not appear to vary across socioeconomic status level.…
