The PsyScope experiment-building system
TLDR
PsyScope is a system for building behavioral experiments on the Apple Macintosh computer using a graphic user interface that requires no computer programming.Abstract:
PsyScope is a system for building behavioral experiments on the Apple Macintosh computer using a graphic user interface that requires no computer programming. The program supports a wide variety of experimental designs, multimedia formats, and stimulus control. A freeware version is available at the author's web site.read more

Tracking the Hemodynamic Responses to Reward and Punishment in the Striatum
TL;DR: An event-related functional magnetic resonance imaging paradigm is developed to identify brain areas that are activated after presentation of a reward and shows differential responses to reward and punishment.
Journal ArticleDOI
Brain areas underlying visual mental imagery and visual perception: an fMRI study.
TL;DR: Although the vast majority of activated voxels were activated during both conditions, the spatial overlap was neither complete nor uniform; the overlap was much more pronounced in frontal and parietal regions than in temporal and occipital regions, which may indicate that cognitive control processes function comparably in both imagery and perception.
Journal ArticleDOI
Perceptions of moral character modulate the neural systems of reward during the trust game
TL;DR: As expected from previous studies, activation of the caudate nucleus differentiated between positive and negative feedback, but only for the 'neutral' partner, suggesting that prior social and moral perceptions can diminish reliance on feedback mechanisms in the neural circuitry of trial-and-error reward learning.

Cortical analysis of visual context.
Moshe Bar,Elissa Aminoff +1 more
TL;DR: This work has revealed the cortical mechanisms that are uniquely activated when people recognize highly contextual objects and indicates that a region in the parahippocampal cortex and a regions in the retrosplenial cortex together comprise a system that mediates both spatial and nonspatial contextual processing.

TL;DR: FMRI data suggest that the amygdala may be responsive to a general category of biologically relevant stimuli such as food, whereas separate ventromedial prefrontal systems may be activated depending on the perceived reward value or motivational salience of food stimuli.

PsyScope: An interactive graphic system for designing and controlling experiments in the psychology laboratory using Macintosh computers
TL;DR: The overall organization of the PsyScope program is described, an example of how a simple experiment can be constructed within its graphic environment is provided, and some of its technical features are discussed.

SuperLab: General-purpose Macintosh software for human experimental psychology and psychological testing.
TL;DR: SuperLab is a general-purpose psychology testing package for the Macintosh that presents static visual and auditory stimuli in blocks of trials, each trial consisting of a user-specified sequence of stimuli.

The Morphonome image psychophysics software and a calibrator for Macintosh systems.
TL;DR: Software for measurement of psychophysical thresholds with 2D moving and coloured images is described, which is menu-driven and has contrast resolution to 0.2% without hardware modifications.

Toolbox-based routines for Macintosh timing and display
TL;DR: Pascal routines are described for several real-time operations on Macintosh computers for millisecond timing and for high-speed transfer of arbitrary bit-image displays to the screen.
