Arrows of time in early childhood.

Three studies with 149 children were conducted to provide information about development of the perception of temporally unidirectional transformations, such as dropping blocks or breaking a cookie. Children 3.5 through 6.5 years of age compared forward ...

The serotonin 5-HT4 receptor and the amyloid precursor protein processing.

A large body of evidence supports a major role for the serotonin 5-HT(4) receptor in learning and memory and it is suggested that 5-HT(4) agonists may be beneficial for memory disorders such as Alzheimers disease (AD). The 5-HT(4) receptors are members ...

Serum cholesterol, precursors and metabolites and cognitive performance in an aging population.

The present study investigated if a causal relation exists between serum concentrations of precursors and metabolites of cholesterol and cognitive performance in a healthy aging population.Cognitive function addressing four domains of 144 individuals ...

Toward a better understanding of the perception of self-produced speech.

The subject of how humans hear their own voices while speaking has received sporadic attention. Previous investigations suggest that the voice is heard substantially via bone conduction, implying a different transfer function to the ear--perhaps a ...

The use of category and similarity information in limiting hypotheses.

Previous studies have shown that adults usually select diverse evidence for generalizing hypotheses. We investigated what kind of evidence people select in another type of inductive task: limiting hypotheses. Whereas generalizing entails extending a ...

Event-related potential indices of masked repetition priming.

Two experiments sought to identify event-related potential (ERP) correlates of masked repetition priming of words in lists and to verify that such effects are not due to brief prime durations. In Experiment 1, prime stimuli were masked and their ...

ERP correlates of true and false recognition after different retention delays: stimulus- and response-related processes.

Performance and electrophysiological correlates of true and false recognition were examined after short (40 s) and long (80 s) delays. True recognition showed no significant decrease after a long delay, whereas false recognition increased. Early frontal ...

Forward and backward blocking of causal judgment is enhanced by additivity of effect magnitude.

When two causes for a given effect are simultaneously presented, it is natural to expect an effect of greater magnitude. However many laboratory tasks preclude such an additivity rule by imposing a ceiling on effect magnitude-for example, by using a ...

A proper metaphysics for cognitive performance.

The general failure to individuate component causes in cognitive performance suggests the need for an alternative metaphysics. The metaphysics of control hierarchy theory accommodates the fact of self-organization in nature and the possibility that ...

Aromas of rosemary and lavender essential oils differentially affect cognition and mood in healthy adults.

This study was designed to assess the olfactory impact of the essential oils of lavender (Lavandula angustifolia) and rosemary (Rosmarlnus officinalis) on cognitive performance and mood in healthy volunteers. One hundred and forty-four participants were ...
