Summary

Accommodation

The test was administered under three conditions: Standard administration, Standard administration with delayed reinforcement, Standard administration with immediate reinforcement

Participants

Experiment 1: Participants included 33 black, second grade children attending an inner city, public elementary school. All children were from families of low socioeconomic status.
Experiment 2: Participants included 33 white, second grade children, all from families of low socioeconomic status.

Dependent Variable

Two tests were administered: Slosson Intelligence Test (1963), a 10 minute verbal test, to assess equality of the groups with respect to IQ; WISC-R Intelligence Test except the Mazes subtest.

Findings

Experiment 1: Results show that black, low-income second graders scored an average of 13 IQ points higher in the immediately reinforced condition than the black children tested under standard conditions or with delayed reinforcement.
Experiment 2: The white, low income, second graders scored eight points higher under the immediate reinforcement condition, but this was not statistically significant and was not higher than the delayed reinforcement group.
