Contrast effects in priming paradigms: Implications for theory and research on implicit attitudes.

30 Aug 2009 Contrast effects have been studied in dozens of experimental paradigms, including the measurement of attitudes in the social psychological literature. However, nearly all of this work has been conducted using explicit reports. In the present ...

A bound on modeling error in observable operator models and an associated learning algorithm.

30 Aug 2009 Observable operator models (OOMs) generalize hidden Markov models (HMMs) and can be represented in a structurally similar matrix formalism. The mathematical theory of OOMs gives rise to a family of constructive, fast, and asymptotically correct ...

Associative sequence learning: the role of experience in the development of imitation and the mirror system.

25 Aug 2009 A core requirement for imitation is a capacity to solve the correspondence problem; to map observed onto executed actions, even when observation and execution yield sensory inputs in different modalities and coordinate frames. Until recently, it was ...

Associative conditioning tunes transient dynamics of early olfactory processing.

17 Aug 2009 Odors evoke complex spatiotemporal responses in the insect antennal lobe (AL) and mammalian olfactory bulb. However, the behavioral relevance of spatiotemporal coding remains unclear. In the present work we combined behavioral analyses with calcium ...

Patterns of brain activity during a semantic task differentiate normal aging from early Alzheimer's disease.

12 Aug 2009 In a study of the effects of normal and pathological aging on semantic-related brain activity, 29 patients with Alzheimer's disease (AD) and 19 controls subjects (10 young and 9 older controls) performed a version of the Pyramids and Palm Trees Test ...

Shift from hippocampal to neocortical centered retrieval network with consolidation.

10 Aug 2009 The standard model of system-level consolidation posits that the hippocampus is part of a retrieval network for recent memories. According to this theory, the memories are gradually transferred to neocortical circuits with consolidation, where the ...

Function follows form: ecological constraints on odor codes and olfactory percepts.

7 Aug 2009 Sensory system function has evolved to meet the biological needs of organisms, but it is less often regarded that sensory system form has by necessity evolved to contend with the stimulus. For an olfactory system extracting meaningful information ...

Computational modeling and empirical studies of hippocampal neurogenesis-dependent memory: Effects of interference, stress and depression.

Aug 2009 Prolonged stress causes dysregulation in the hypothalamic-pituitary-adrenal axis and may contribute to the pathogenesis of major depressive disorder (MDD). MDD is associated with pathological changes in several brain regions, particularly the ...

Interpreting patterns of brain activation in human fear conditioning with an attentional-associative learning model.

30 Jul 2009 J. E. Dunsmoor, P. A. Bandettini, and D. C. Knight conducted a neuroimaging study of human fear conditioning and analyzed brain activity under various pairing rates between a conditioned and an unconditioned stimulus. Computer simulations with an ...

Using virtual reality to assess young adult smokers' attention to cues.

30 Jul 2009 Cigarette smokers, when confronted with cues associated with smoking, evidence strong reactions, including increased attentional bias toward those smoking-related cues. These reactions have not been extensively studied in young adult smokers, a ...
