The role of modality congruence in the presentation and recognition of task-irrelevant stimuli in dual task paradigms
Explicitly presented task-irrelevant targets are facilitated in a later recognition test, provided they frequently appear synchronously with targets from a previously presented relevant task (Dewald & Sinnett, 2013). This dual task paradigm was used to test the relationship between the modality of which a primary task was presented, and the modality of a subsequently presented secondary task. E...
متن کاملOscillatory brain activity during a motor task.
Changes in spectral power in neuromagnetic fields associated with a manual task requiring a high level of sensorimotor integration (SMI) were investigated by analysing spontaneous, non-invasively recorded activity during motor preparation (WAIT), task performance (SMI), and control (REST) conditions in four healthy, right-handed human subjects. Neuromagnetic fields were recorded over the left s...
متن کاملNovel response patterns during repeated presentation of affective and neutral stimuli.
Repeated stimulus presentations are commonly used in social and affective neuroimaging tasks, but much remains to be known about how the brain processes such repetitions. Using functional magnetic resonance imaging, we found three groups of brain regions with distinct response patterns during repeated presentations of natural scene images. One group consisted of several limbic, paralimbic, fron...
متن کاملAge-related shifts in brain activity dynamics during task switching.
Cognitive aging studies have suggested that older adults show declines in both sustained and transient cognitive control processes. However, previous neuroimaging studies have primarily focused on age-related change in the magnitude, but not temporal dynamics, of brain activity. The present study compared brain activity dynamics in healthy old and young adults during task switching. A mixed blo...
متن کاملCharacterizing “fibrofog”: Subjective appraisal, objective performance, and task-related brain activity during a working memory task
The subjective experience of cognitive dysfunction ("fibrofog") is common in fibromyalgia. This study investigated the relation between subjective appraisal of cognitive function, objective cognitive task performance, and brain activity during a cognitive task using functional magnetic resonance imaging (fMRI). Sixteen fibromyalgia patients and 13 healthy pain-free controls completed a battery ...
