Kinematics and dynamics are not represented independently in motor working memory: evidence from an interference study.

Our capacity to learn multiple dynamic and visuomotor tasks is limited by the time between the presentations of the tasks. When subjects are required to adapt to equal and opposite position-dependent visuomotor rotations (Krakauer et al., 1999) or ...

Time, space, and short-term memory.

This article describes a linear timekeeping system that can account for four main results from the human time-production literature: (1) Variability of interresponse intervals (IRIs) in repetitive finger-tapping tasks increases with mean IRI; (2) The ...

Event-related potentials index cognitive style differences during a serial-order recall task.

Working memory and attentional inhibition processes (jointly symbolized here as WM/I) have been proposed to explain cognitive style differences in Field Dependence-Independence (FDI). FI relative to FD subjects have been found to use more effectively ...

A jigsaw-puzzle imagery task for assessing active visuospatial processes in old and young people.

Recent studies have suggested a theoretical distinction between active elaboration and passive storage in visuospatial working memory, but research with older adults has failed to demonstrate a differential preservation of these two abilities. The ...

Striatal contribution to cognition: working memory and executive function in Parkinsons disease before and after unilateral posteroventral pallidotomy.

The basal ganglia are intimately connected to the frontal cortex via five fronto-striatal circuits. While the role of the frontal cortex in cognition has been extensively studied, the contribution of the basal ganglia to cognition has remained less ...

Specificity of brain activation patterns in people at genetic risk for Alzheimer disease.

Previous studies with positron-emission tomography (PET) and functional magnetic resonance imaging (fMRI) have indicated differences in neural metabolism and activity between carriers of the APOE epsilon4 allele and those who are not at risk for ...

The neural substrate of orientation short-term memory and resistance to distractor items.

We used Positron Emission Tomography to map the neural substrate of human short-term memory for orientation, defined as retaining a single orientation in memory over a long delay, by comparing a successive discrimination task with a 6-s delay to the same ...

The sandwich effect reassessed: effects of streaming, distraction, and modality.

The degree of disruption from interleaving auditory irrelevant items within a sequence of to-be-remembered items--the sandwich effect--was examined in two experiments. Previous demonstrations of the effect have shown that the penalty for interleaving ...

Adrenocortical stress responses and altered working memory performance.

This study examined stress cortisol responses and cognitive performance. We initially measured cortisol responses of 40 right-handed healthy male volunteers to counterbalanced mental arithmetic and public speaking stressors. We then examined the ...

What information underlies correct rejections in short-term recognition memory?

We propose that correct rejections are based on information that contradicts the study set, rather than on insufficient familiarity. Using two-dimensional stimuli, we varied the featural overlap between lures and the study set so that one feature of the ...
