“…Examples of cognitive interventions are programs directed at preschoolers, such as High/Scope (Weikart, Rogers, Adcock, & McClelland, 1971;Berrueta, Schweinhart, Barnett, Epstein, & Weikart, 1984;Heckman, et al 2010), the Abecedarian project (Ramey & Campbell, 1984;Campbell et al, 2012), andHead Start (Zigler, 1979), "patterning" instruction in early elementary school (Pasnak, et al 2015), and "Instrumental Enrichment" for adolescents (Feuerstein, Rand, Hoffman, & Miller, 1980;Blagg, 1991). Some of these efforts have been based on extant theory (e.g, Weikart et al 1971;Kidd et al, 2012)); others more eclectically on anything that seemed to the originators to be potentially useful (Gray & Klaus, 1970).…”
