“…As described below, these strength manipulations allow us to compute one of the critical statistics of SFT which can enable us to determine the nature of the processes by which item and associative information are retrieved and the extent to which they interact (for an overview and tutorial on SFT, see Houpt et al, 2014).…”

Memory contains information about individual events (items) and combinations of events (associations). Despite the fundamental importance of this distinction, it remains unclear exactly how these two kinds of information are stored and whether different processes are used to retrieve them. We use both model-independent qualitative properties of response dynamics and quantitative modeling of individuals to address these issues. Item and associative information are not independent and they are retrieved concurrently via interacting processes. During retrieval, matching item and associative information mutually facilitate one another to yield an amplified holistic signal. Modeling of individuals suggests that this kind of facilitation between item and associative retrieval is a ubiquitous feature of human memory.

“…If the selective-influence assumption holds, we would expect that the former four tests are significant, and the latter four tests are not significant. See Houpt et al (2014) for more details. In addition, we tested the reaction time distributions at the factor level.…”

“…We adopted a nonparametric bootstrapping method (Van Zandt, 2000) and utilized statistics from the sft R package (Houpt, Blaha, McIntire, Havig, & Townsend, 2014) to analyze the reaction time data and make inferences. All analyses were conducted separately for each individual.…”

“…If the 95 % CI for SIC does not include 0 for all times t, we would infer that SIC is not equal to 0. In addition, we used the sft R package (Houpt et al, 2014) to separately assess the positive-going deviations from SIC = 0 and the negativegoing deviations from SIC = 0. Two one-sided K-S tests were conducted; one test tests whether the largest positive value of the SIC (D+) is significantly different from zero, and the other test tests whether the largest negative value of the SIC (D-) is significantly different from zero.…”

“…A significant interaction effect would indicate that MIC is not 0 and that the two factors are nonadditive. Second, a nonparametric adjusted rank transform test (Houpt et al, 2014) was conducted to test for the interaction between the two factors. Similar to the ANOVA, a significant interaction indicates that MIC is not equal to zero.…”

Selective attention modulates the effect of target location probability on redundant signal processing

We investigated the decision process underlying the detection of targets at multiple locations. In three experiments using the same observers, target location probability and attentional instructions were manipulated. A redundanttarget detection task was conducted in which participants were required to detect a dot presented at one of two locations. When the dot appeared at the two locations with equal frequency (Experiment 1), those participants who were found to have limited to unlimited capacity were shown to adopt a parallel, self-terminating strategy. By contrast, those participants who had supercapacity were shown to process redundant targets in a coactive manner. When targets were presented with unequal probability, two participants adopted a parallel, self-terminating strategy regardless of whether they were informed the target location probability (Experiment 3) or not (Experiment 2). For the remaining two participants, the strategy changed from parallel, self-terminating to serial, selfterminating as a result of the probability instructions. In Experiments 2 and 3, all the participants were of unlimited to limited capacity. Taken together, these results suggest that target location probability differently affects the selection of a decision strategy and highlight the role of controlled attention in selecting a decision strategy.

This chapter is a tutorial on and review of a theory‐driven, quantitative approach to studying human information processing systems. Key properties in such systems comprise mental architecture, workload capacity, decisional stopping rules, and several varieties of independence, among others. We outline the early history of such interests, which began in the 19th century and then were reopened in the 1960s. We point out the hazards due to the frequent ability of even mathematically specified models to mimic each other's experimental predictions. Next, we show how the deepest properties of distinct psychological principles can, through what we term “meta‐theory,” be engaged to prove powerful theorems regarding model distinctions and transferred to incisive experimental designs that avoid the dilemma of model mimicry. This meta‐theory and its associated experimental designs have been implemented to address a wide variety of theoretical and empirical questions regarding attention, perception, psychophysics, memory processes, decision making, and categorization. This range of implementations—running from basic science to applied arenas such as clinical pathologies and human factors research—underscores the generality and potency of this approach.
