Experimental design (schematic). Each trial comprises three phases: stimulus presentation, motor response, and reinforcement. Firstly, a fractal object appears (center), surrounded by four response options (grey discs). Secondly, the observer reacts by pressing the key that corresponds to one response option (outlined disk). Thirdly, a color change of the chosen option provides reinforcement (green if correct, red if incorrect). (b) Object sequence with temporal context. Target objects recur every 2 to 48 trials. Thus, successive trials always present different objects. A consistent temporal context is created by the fact that each target object (e.g., trials t and t + m) is preceded consistently by a specific (other) object (trials t - 1 and t + m - 1). (c) Object sequence without temporal context. Each time an object appears (trials t and t + m), it is preceded by a different object (trials t - 1 and t + m - 1).
