Effects of depressed mood on objective and subjective measures of attention.

People with depression report frequent cognitive failures, but objective measures of cognition show mixed results. Some studies show impairment on effortful tasks. The relationship between subjective and objective cognitive failures was studied in 102 ...

Implicit temporal tuning of working memory strategy during cognitive skill acquisition.

Complex cognitive tasks such as multiple-step arithmetic entail strategies for coordinating mental processes such as calculation with processes for managing working memory (WM). Such strategies must be sensitive to factors such as the time needed for ...

Mechanisms of differences in gating effects on short-and long-latency somatosensory evoked potentials relating to movement.

We investigated the mechanisms underlying the differences in gating effects on short- and long-latency somatosensory evoked potentials (SEPs) relating to movement. SEPs were recorded in normal subjects for 6 different tasks in Experiment 1: Control, ...

On the topography of P3a and P3b across the adult lifespan--a factor-analytic study using orthogonal procrustes rotation.

The purpose of this study was to investigate whether the activity distribution of P3a and P3b across the scalp changes with age or remains identical. 103 well-functioning adults, 20-90 years, performed a visual three-stimuli oddball ERP task yielding ...

P3a from visual stimuli: typicality, task, and topography.

A visual three-stimulus (target, nontarget, standard) paradigm was employed in which subjects responded only to the target. Nontarget stimulus properties were varied systematically to evaluate how stimulus typicality (non-novel vs. novel) across task ...

Grammatical intuitions about irregular verb inflections.

If people possess a rule that the root of a verb plus -ed produces the past tense, why does this rule produce an unacceptable form when applied to an irregular verb (e.g., comed)? One possibility is that the unacceptability of comed is the result of ...

Measuring the activation level of critical lures in the Deese-Roediger-McDermott paradigm.

In four experiments, the activation level in memory of critical lures was assessed after encoding Deese-Roediger-McDermott (DRM) lists. The results demonstrated that studying longer, 14-item lists resulted in superadditive priming of the lures because ...

Augmentation of auditory N1 in children with fragile X syndrome.

We compared the N1 responses of the auditory event-related brain potentials (ERPs) in school-aged children with fragile X syndrome to age-matched controls in order to assess auditory processing. Event-related potentials to non-attended standard and ...

Modeling the effect of task and graphical representation on response latency in a graph reading task.

We report an investigation into the processes involved in a common graph-reading task using two types of Cartesian graph. We describe an experiment and eye movement study, the results of which show that optimal scan paths assumed in the task analysis ...

Age-related changes in brain responses to personally known faces: an event-related potential (ERP) study in humans.

Midlife period has not been investigated so far regarding associations between brain responses and spared abilities for face processing. This study examines the effects of midlife aging on behavioural performance and event-related potentials (ERPs) ...
