Semantic interference from visual object recognition on visual imagery.

A new technique for examining the interaction between visual object recognition and visual imagery is reported. The "image-picture interference" paradigm requires participants to generate and make a response to a mental image of a previously memorized ...

Cognitive effects of nicotine in humans: an fMRI study.

To elucidate the neural correlates of cognitive effects of nicotine, we examined behavioral performance and blood oxygenation level-dependent regional brain activity, using functional magnetic resonance imaging, during a parametric "n-back" task in ...

Evaluating subject specific preprocessing choices in multisubject fMRI data sets using data-driven performance metrics.

This study investigated the possible benefit of subject specific optimization of preprocessing strategies in functional magnetic resonance imaging (fMRI) experiments. The optimization was performed using the data-driven performance metrics developed ...

The minds eye: functional MR imaging evaluation of golf motor imagery.

BACKGROUND AND PURPOSE: Mental imagery involves rehearsing or practicing a task in the mind with no physical movement. The technique is commonly used, but the actual physical foundation of imagery has not been evaluated for the fast, complex, automatic ...

The use of EEG modifications due to motor imagery for brain-computer interfaces.

The opening of a communication channel between brain and computer [brain-computer interface (BCI)] is possible by using changes in electroencephalogram (EEG) power spectra related to the imagination of movements. In this paper, we present results ...

Separating emotion and motivational direction in fear and anger: effects on frontal asymmetry.

State effects on frontal alpha electroencephalograph asymmetry (ASY) are thought to reflect approach and withdrawal motivational tendencies. Although this motivational direction model has inspired a large body of research, efforts to disentangle ...

The Snodgrass and Vanderwart set revisited: norms for object manipulability and for pictorial ambiguity of objects, chimeric objects, and nonobjects.

In this paper, we propose a standardized set of 480 black-and-white line drawings, half meaningful and half meaningless. Meaningful pictures represent a common object, and were selected from the Snodgrass and Vanderwart set (1980). Meaningless pictures ...

Neural correlates underlying mental calculation in abacus experts: a functional magnetic resonance imaging study.

Experts of abacus operation demonstrate extraordinary ability in mental calculation. There is psychological evidence that abacus experts utilize a mental image of an abacus to remember and manipulate large numbers in solving problems; however, the neural ...

Exploring the role of repetition and sensory elaboration in the imagination inflation effect.

Two experiments were conducted to examine whether a misattribution of specific characteristics or a misattribution of global familiarity underlies false memories as assessed through imagination inflation. Using the paradigm developed by Goff and Roediger ...

Sensory perception during sleep and meditation: common features and differences.

Sleep and meditation are both physiological conditions in which peripheral sensory input is voluntarily reduced, but sensory perception of internally generated information continues. However, the two conditions differ in the level of awareness ...
