Selective influence of experimental factors upon observable or hypothetical random variables is a key concept in the analysis of processing architectures and response time decompositions. This paperâ€¦ (More)

We analyze sets of mental processes, some of which are concurrent and some of which are sequential, under the assumption that the processes are partially ordered, that is, arranged in a directedâ€¦ (More)

E. N. Dzhafarov and R. Schweickert (1995, Journal of Mathematical Psychology, 39, 285-314) developed a mathematical theory for the decomposability of response time (RT) into two component times thatâ€¦ (More)

Among the possible response time (RT) decomposition rules, three are of a traditional interest: addition (serial RT architecture), minimum (parallel-OR architecture), and maximum (parallel-ANDâ€¦ (More)

The apparent contraction of spatial separation between moving visual objects along the direction of motion (Space Contraction in Motion effect, SCM) occurs under both steady fixation and free lookingâ€¦ (More)

Consider two sets of objects, {alpha(1), em leader, alpha(n)} and {beta(1), em leader, beta(m), such as n subjects solving m tasks, or n stimuli presented first and m stimuli presented second in aâ€¦ (More)
