Implicit scene learning is viewpoint dependent.

When novel scenes are encoded, the representations of scene layout are generally viewpoint specific. Past studies of scene recognition have typically required subjects to explicitly study and encode novel scenes, but in everyday visual experience, it is ...

Dynamics-based sequential memory: winnerless competition of patterns.

We introduce a biologically motivated dynamical principle of sequential memory which is based on winnerless competition (WLC) of event images. This mechanism is implemented in a two-layer neural model of sequential spatial memory. We present the learning ...

Acute alcohol effects on cognitive function in social drinkers: their relationship to drinking habits.

RATIONALE: Several studies suggest that cognitive deficits seen in late stages of alcoholism are related to executive function. However, little is known about the acute effects of alcohol on cognitive executive functions. AIMS: The present investigation ...

High-fidelity perceptual long-term memory revisited--and confirmed.

Experiments on short-term perceptual memory for elemental visual attributes, such as contrast, motion, orientation, and spatial frequency, have relied on a delayed discrimination technique in which the subject compares two stimuli presented at different ...

Time course of processes and representations supporting visual object identification and memory.

Event-related potentials (ERPs) were used to delineate the time course of activation of the processes and representations supporting visual object identification and memory. Following K. Srinivas (1993), 66 young people named objects in canonical or ...

The Maudsley Bipolar Disorder Project: the effect of medication, family history, and duration of illness on IQ and memory in bipolar I disorder.

BACKGROUND: Despite the growing recognition of the importance of cognitive impairment in psychiatric disorders, the effect of clinical factors, such as medication use and family history of affective disorders, on cognition in bipolar I disorder patients ...

Implicit memory for words presented in short texts is preserved in Alzheimers disease.

BACKGROUND: The level of efficiency of implicit memory in Alzheimers disease remains unclear as previous studies using stem completion tasks have led to contradictory results. METHOD: The present study used target words embedded in significant short ...

Comprehension of algebraic expressions by experienced users of mathematics.

Little is known about how people comprehend mathematical expressions. In the present study we investigate the internal representations used by experienced users of mathematics to encode algebraic expressions. Initially, a memory recognition task was ...

Genetic linkage and association between chromosome 1q and working memory function in schizophrenia.

Schizophrenia is substantially heritable, but specific susceptibility genes remain to be identified. Progress in this endeavor has been hindered by non-Mendelian transmission patterns, probable genetic heterogeneity, and an inability to detect premorbid ...

The regularities of the discrete nature of multi-variability of EEG spectral patterns.

The short-term structure of electroencephalogram (EEG) spectral transformations during different brain functional states (closed/opened eyes and memory task) was studied. It was shown that approximately 50% of spectral pattern (SP) types occur not more ...
