Psychophysics experiments often require passing messages and signals between different computers and devices. There are a number of methods that are generally used and the limitations of these methods are often a source of consternation for researchers.
Experiments designed to probe human temporal perception are particularly sensitive to timing errors in the apparatus. Therefore we have …

Arduino I/O and Dynamic Graphing with R and the Manipulate library

Recently, our lab has been working on a general timing measurement system to ensure that psychophysical timing of experiments is valid with different experimental setups ranging from calibrated lab CRT monitors to LCD projectors in MRI facilities.
Essentially, we aim to have a portable and easy to use recorder of digital and analogue signals that can …
