“…No consistent effects have been found in this research. In nearly all studies, null results have been obtained for the color–performance relation (Ainsworth, Simpson, & Cassell, 1993; Goodfellow & Smith, 1973; Green et al, 1982; Hammes & Wiggins, 1962; Hatta et al, 2002; Isaacs, 1980; Kwallek & Lewis, 1990; Kwallek, Lewis, Lin-Hsiao, & Woodson, 1996; Kwallek, Lewis, & Robbins, 1988; Kwallek et al, 1997; Pierce & Weinland, 1934; Pressey, 1921; Profusek & Rainey, 1987; Rosenstein, 1985; Shick, 1975; Stone & English, 1998). A few studies have yielded data indicating worse performance under red conditions (James & Domingos, 1953; Nakashian, 1964; Sinclair, Soldat, & Mark, 1998; Soldat et al, 1997; Stone, 2001), but another study found the opposite pattern (Hill & Barton, 2005).…”
