Illustration of the architecture of the Adjusted Expectancy Model. Two identical stages, each consisting of two competitive units of alternative representations, are connected in series. Cues are interpreted in central units leading to increased activation of the corresponding representation at perceptual and motor stages of processing. Target stimuli activate their representations at the perceptual stage. When the target activates the representation that was activated by the cue, central units are informed (dotted line) to provide additional activation for the cued representations at the motor stage. When the target and the cue activate different representations at the perceptual stage, central units are informed to reduce the additional activation of the cued representation at the motor stage. Expectancy interaction occurs because the evaluation of perceptual expectancies modulates post-target activation of motor representations. Note, excitatory links end with an arrow, and inhibitory links end with a dot. Only examples of essential links are included to illustrate the basic principles of the model (see ).
