“…A substantial body of evidence on interference between cues trained apart comes also from the classical studies on retroactive interference in the verbal learning tradition (e.g., Slamecka & Ceraso, 1960;Underwood, 1966). Although researchers in the interference tradition more extensively studied retroactive interference with the A-B, A-C paradigm (i.e., two different outcomes associated to a common cue; e.g., Bäuml, 1996Bäuml, , 1998Chandler, 1993;Chandler & Gargano, 1998), many experiments have shown that interference can also take place when two different cues are associated to a common outcome (i.e., the A-B, C-B paradigm; see, e.g., Abra, 1967;Cheung & Goulet, 1968;Johnston, 1968;Keppel, Bonge, Strand, & Parker, 1971;Schwartz, 1968).…”
