Schematic depiction of the consequences of competition and top–down bias. Under high load, competition impairs target representation (top panel) and thus a top–down bias is necessary to resolve the target (bottom), which in turn filters out the distractor. Under low load, the target representation is already clear (top panel) and thus no bias is needed to perform the task (bottom panel).
