![]() ![]() Sequential effects can be categorized as first-order (caused by the immediately previous trial) or higher-order (caused by trials earlier in the sequence). We follow this convention, denoting the two response choices by “1” and “2.” Most of the literature on such effects concerns two-alternative forced-choice (2AFC) tasks, and stimulus sequences are represented using repetition ( R) and alternation ( A) to indicate whether a given trial is a repetition or alternation of the previous one. ![]() This sequential effect has been widely tested under different conditions and with various auditory and visual stimuli Soetens et al. The results also suggest that practice speeds up all the mechanisms rather than adjusting their relative strengths.Įven when subjects are instructed that stimulus sequences are randomly ordered, their reaction times (RTs) and error rates (ERs) on serial RT tasks typically depend upon previous trials in a systematic manner. Equipped with these mechanisms, the network, consistent with known neurophysiology, accounts for several sets of behavioral data over a wide range of RSIs. ![]() A further mechanism mediates expectation-related biases that grow during RSI toward saturation levels determined by weighted repetition (or alternation) sequence lengths. A study of separate biasing mechanisms shows that residual decision unit activity can lead only to first-order AF, but higher-order AF can result from strategic priming mediated by conflict-monitoring, which we instantiate in two distinct versions. To illuminate the sources of such effects, we develop a connectionist network of two mutually-inhibiting neural decision units subject to feedback from previous trials. As response-to-stimulus interval (RSI) increases, the pattern of reaction times transits from a benefit-only mode, traditionally ascribed to automatic facilitation (AF), to a cost-benefit mode, due to strategic expectancy (SE). This will place the last version of the product your serial will cover, onto the machine.Performance on serial tasks is influenced by first- and higher-order sequential effects, respectively due to the immediately previous and earlier trials.
