“…Brooks-Gunn, Rouse, and McLanahan (2007) noted that research identifying how attention and self-control contribute to achievement gaps across ethnicities is necessary. Characteristics of the home environment influence achievement cross-ethnically and cross-culturally (Assadi et al, 2007) and in specific investigations of Latino-subgroup samples (e.g., El Savadoran, Mexican American, and Puerto Rican participants; De Von Figueroa-Moseley, Ramey, Keltner, & Lanzi, 2006). Although meanlevel differences in achievement exist, predictors of and processes leading to achievement are likely to be similar across groups (Blair & Razza, 2007;Crosnoe, 2006;Valiente et al, 2008).…”
