Beta values are reported from four separate linear regressions in which anesthesia status, age at testing, total problems CBCL, gender, total IQ, and family income predict color recollection, spatial recollection, color familiarity, or spatial familiarity, respectively. SE for each coefficient is reported in parentheses below each standardized beta coefficient. Results reveal ΔR² (root mean squared error) for color recollection, 0.21 (0.20); spatial recollection, 0.14 (0.20); color familiarity 0.06 (0.60); and spatial familiarity 0.16 (0.68), with N=56, in each case.
