Affect 4.0

Welcome to the Affect 4.0 pages. Affect is a software package developed to assemble and conduct psychological experiments. The interface of Affect is designed so that you do not need to have specific programming skills : experiments can be programmed 'button-wise' through an intuitive user interface.

The main goal of Affect is not to provide a programming language or a complex authoring studio oriented towards complex experiments. Instead, Affect is born out of a need for software that makes it easier for experimenters to define randomisations, timings, and output of experiments that consist of many identical and independent trials. As such, the major advantage of Affect is the ease with which one can define semi-randomisations (a lot of similar programming shells miss this possibility) and quickly create trial pools from stimulus sets.

Affect allows audiovisual presentations (e.g. WAV, BMP, ..) and can trigger external devices (e.g. electroshock device, slide projector). Affect registers response latencies (e.g. voice key, keyboard) with continuous feedback from the subject. Timing is millisecond-accurate if the computer meets the proper technical requirements.

Affect has build-in support for interfacing with LabMaster A/D converter hardware
