“…A slight majority of investigations support the basic tenets of the equilibrium theory (Buchanan, Goldman, & Juhnke, 1977;Coutts & Ledden, 1977;Goldberg & Wellens, 1979;Greenbaum & Rosenfeld, 1978;Greenberg & Firestone, 1977;Hardee, 1976;Johnson & Dabbs, 1976;Knight, Langmeyer, & Lundgren, 1973;McAulay, 1977;Nottingham, 1979;Patterson, 1973aPatterson, , 1977Scherer & Schiff, 1973), and several other studies find at least partial support (Baker & Shaw, 1980;Coutts & Schneider, 1976;Eberts & Lepper, 1975;Hughes & Goldman, 1978;Lassen, 1973;Mooney, 1976;Sundstrom, 1978;Walden & Forsyth, 1981). More than a few studies do not support equilibrium theory (Breed, 1972;Carr & Dabbs, 1974;Castell, 1970b;Chapman, 1975;Kleinke et al, 1975;Lockard, McVittie, & Isaac, 1977;Marcelle, 1977;Schneider &Hansvick, 1977;Stephensen, Rutter, & Dore, 1973), but it seems that these are unlikely to discourage continued discussion of the theory.…”
