Ten years Diffusion Model for Conflict (DMC) tasks
A central question in cognitive psychology concerns how humans selectively attend to task-relevant information while ignoring task-irrelevant information. This question is frequently studied using conflict tasks, such as the Simon, Eriksen flanker, and Stroop tasks that require responses to relevant stimulus features while ignoring irrelevant and potentially conflicting features. All conflict tasks produce better performance in congruent trials w…
Evidence against independence of peripheral latencies and central threshold in temporal-order perception
Independent-channels models of temporal-order and simultaneity perception assume that a central (amodal) timing mechanism compares the arrival times of incoming sensory signals independently of peripheral (modal) events. This implies that peripheral latencies and central threshold are additive. The present study tested whether the central threshold is invariant to intramodal versus intermodal stimulation (Experiment 1) and strong versus weak inte…
Decomposing delta plots
When assessing the time-course of evidence accrual in conflict tasks, delta plots are often employed to show the time course of congruency effects. However, delta plots on reaction time and response errors only capture the differences between the congruent and incongruent conditions, detailing that a pattern or shift is occurring, but not what contributes to creating these changes. To gain a clearer idea of what is causing these trends and shifts…
Evaluating three independent-channels models of temporal-order and simultaneity judgment
How do people judge the temporal order and simultaneity/successiveness of events? Three candidate models can explain the theoretically constraining shapes of the psychometric functions observed in tasks with more complex response formats. First, the response-error model allows that internal states generated by a triggered-moments process are misreported due to finger errors, requiring that psychometric functions are parallel after empirically acc…
Order effects in stimulus discrimination challenge established models of comparative judgement
This paper provides a comprehensive review of the Type B effect (TBE), a phenomenon reflected in the observation that discrimination sensitivity varies with the order of stimuli in comparative judgment tasks, such as the two-alternative forced-choice (2AFC) paradigm. Specifically, when the difference threshold is lower (higher) with the constant standard preceding rather than following the variable comparison, one speaks of a negative (positive) …
Modal and amodal cognition
Accounting for how the human mind represents the internal and external world is a crucial feature of many theories of human cognition. Central to this question is the distinction between modal as opposed to amodal representational formats. It has often been assumed that one but not both of these two types of representations underlie processing in specific domains of cognition (e.g., perception, mental imagery, and language). However, in this pape…
Wilhelm Wundt
In 1851, Wilhelm Wundt embarked on his university journey at the University of Tübingen, initially enrolling as a medical student. This article draws from Wundt's autobiography and supplementary sources to illuminate the motivations behind his choice of Tübingen, shedding light on how this pivotal phase influenced both his scientific trajectory and his personal development. It offers insights into Wundt's perspectives on university and city life …
Self-protecting responses in randomized response designs
Randomized response techniques (RRTs) are applied to reduce response biases in self-report surveys on sensitive research questions (e.g., on socially undesirable characteristics). However, there is evidence that they cannot completely eliminate self-protecting response strategies. To address this problem, there are RRTs specifically designed to measure the extent of such strategies. Here we assessed the recently devised unrelated question model—c…
The role of task-relevant and task-irrelevant information in congruency sequence effects
Cheater Detection Using the Unrelated Question Model
Randomized response techniques (RRTs) are useful survey tools for estimating the prevalence of sensitive issues, such as the prevalence of doping in elite sports. One type of RRT, the unrelated question model (UQM), has become widely used because of its psychological acceptability for study participants and its favorable statistical properties. One drawback of this model, however, is that it does not allow for detecting cheaters-individuals who d…
The time-course of distractor-based activation modulates effects of speed-accuracy tradeoffs in conflict tasks
The cognitive processes underlying the ability of human performers to trade speed for accuracy is often conceptualized within evidence accumulation models, but it is not yet clear whether and how these models can account for decision-making in the presence of various sources of conflicting information. In the present study, we provide evidence that speed-accuracy tradeoffs (SATs) can have opposing effects on performance across two different confl…
The action-sentence compatibility effect (ACE)
Short-term memory of temporal information revisited
Previous studies provided diverging evidence regarding modality specificity of temporal information in short-term memory. Some authors reported modality-specific interference effects on visual and auditory duration discrimination, whereas others observed crossmodal interference effects. One reason for these diverging results could be different trade-offs between the temporal discrimination task and the interference task in these studies. Therefor…
Is rushing always faster than strolling? A reaction time study on the processing of sentences containing manner of motion verbs
In the context of the embodied cognition debate, an effect of motion verb associated speed information has previously been detected using eye-tracking, functional magnetic resonance imaging (fMRI), and reaction times (RT). The latter, for instance, was implemented by Wender and Weber (1982), who observed that participants were faster in detecting motion in sentences associated with fast motion compared to sentences associated with slow motion aft…
