Users

Presentation is used in universities and their experiments all over the world, such as * Centre for Cognitive Neuroimaging * Perception, memory and aesthetics of indeterminate art * Common ground for spatial cognition? A behavioral and fMRI study of sex differences in mental rotation and spatial working memory * Contagious yawning and the brain * Stereoscopic Depth and the Occlusion Illusion * Neural mechanisms underlying auditory feedback control of speech * An Interdisciplinary Study of Visual Indeterminacy

Programming

Presentation uses two proprietary scripting languages to describe and control experiments. It also has a Python module allowing the use of Python to control experiments.

SDL (Scenario Description Language)

SDL is a simple language used to describe the stimuli and trials which make up an experiment. Compile-time logic can be used to generate and/or randomize stimuli.

PCL (Program Control Language)

PCL is a fully functioning scripting language based loosely on C and Basic. It uses strong type checking to ensure that the intention of the programmer is explicit. Loops, "if" statements and subroutines are supported. It can be used in conjunction with the objects created in SDL, or used alone to create, manipulate and present stimuli. The editor supports

code completion Autocomplete, or word completion, is a feature in which an application predicts the rest of a word a user is typing. In Android and iOS smartphones, this is called predictive text. In graphical user interfaces, users can typically press the tab ...

Python

Presentation has a Python module which allows users to use

instead of PCL to script their experiments. Anything that can be done in PCL can also be done in Python.
