On the origins of the task mixing cost in the cuing task switching paradigm
, 2005
"... Poorer performance in conditions involving task repetition within blocks of mixed tasks relative to task repetition within blocks of single task is called mixing cost (MC). In 2 experiments exploring 2 hypotheses regarding the origins of MC, participants either switched between cued shape and color ..."

tasks, or they performed them as single tasks. Experiment 1 supported the hypothesis that mixed-tasks trials require the resolution of task ambiguity by showing that MC existed only with ambiguous stimuli that afforded both tasks and not with unambiguous stimuli affording only 1 task. Experiment 2
Pragmatics of measuring recognition memory: Applications to dementia and amnesia.
- Journal of Experimental Psychology: General,
, 1988
"... SUMMARY This article has two purposes. The first is to describe four theoretical models of yesno recognition memory and present their associated measures of discrimination and response bias. These models are then applied to a set of data from normal subjects to determine which pairs of discriminati ..."

's disease patients, and parkinsonian dementia patients were tested with picture recognition tasks with repeated study-test trials. Huntington's disease patients, mixed etiology amnesics, and age-matched normals were tested by Butters, Wolfe, Martone, Three major points are emphasized. First, any index
ORIGINAL ARTICLE Dissociating restart cost and mixing cost in task switching
"... Abstract Three experiments investigated the cognitive mechanisms underlying the restart cost and mixing cost in task switching. To this aim, the predictability of task order was varied (unpredictable in Experiment 1 and predictable in Experiments 2 and 3) across experiments, which employed a multipl ..."

multiple-trial paradigm. Verbal cues for color and shape matching tasks were presented before a run of four trials. Focusing on task-repetition runs only, we measured restart cost as the diVerence in performance between trials 1 and 2 and mixing cost as the diVerence in performance on the non-cued trials
Dissociation of S-R Compatibility and Simon Effects With Mixed Tasks and Mappings
"... Binary-choice reactions are typically faster when the stimulus location corresponds with that of the response than when it does not. This advantage of spatial correspondence is known as the stimulus-response compatibility (SRC) effect when the mapping of stimulus location, as the relevant stimulus d ..."

dimension, is varied to be compatible or incompatible with response location. It is called the Simon effect when stimulus location is task-irrelevant. The SRC effect is eliminated when compatible and incompat-ible spatial mappings are mixed within a trial block, and the Simon effect is eliminated when
Mixing Board Versus Mouse Interaction In Value Adjustment Tasks
, 2011
"... We present a controlled, quantitative study with 12 participants comparing interaction with a haptically enhanced mixing board against interaction with a mouse in an abstract task that is motivated by several practical parameter space exploration settings. The study participants received 24 sets of ..."

Functional-anatomic study of episodic retrieval using fMRI. I. Retrieval effort versus retrieval success.
- NeuroImage
, 1998
"... In a companion paper (R. L. Buckner et al., 1998, NeuroImage 7, 151-162) we used fMRI to identify brain areas activated by episodic memory retrieval. Prefrontal areas were shown to differentiate component processes related to retrieval success and retrieval effort in block-designed paradigms. Impor ..."

. Importantly, a right anterior prefrontal area was most active during task blocks involving greatest retrieval success, consistent with an earlier PET study by M. D. Rugg et al. (1996, Brain 119, 2073-2083). However, manipulation of these variables within the context of blocked trials confounds differences
An Instance-Based Learning Model of Stimulus-Response Compatibility Effects in Mixed Location-Relevant and Location-Irrelevant Tasks
"... This paper presents a cognitive model of stimulus-response compatibility (SRC) effects for a situation in which location-relevant and location-irrelevant tasks are intermixed within a single trial block. We provide a computational explanation of the cognitive processing involved in the mixed-task co ..."

Distinct neurophysiological mechanisms mediate mixing costs and switch costs
- Journal of Cognitive Neuroscience
, 2008
"... & Using event-related potentials (ERPs), we investigated the neural response associated with preparing to switch from one task to another. We used a cued task-switching paradigm in which the interval between the cue and the imperative stim-ulus was varied. The difference between response time (R ..."

The ERPs in response to the cue were compared across three conditions: single-task trials, switch trials, and repeat trials. ERP topographic differences
Cognitive addition: Strategy choice and speed-of-processing differences in gifted, normal, and mathematically disabled children

Task-set switching with natural scenes: Measuring the cost of deploying top-down attention
- Journal of Vision
, 2007
"... In many everyday situations, we bias our perception from the top down, based on a task or an agenda. Frequently, this entails shifting attention to a specific attribute of a particular object or scene. To explore the cost of shifting top-down attention to a different stimulus attribute, we adopt th ..."
