Saccadic latency measurement and analysis

SPIC allows acquisition, analysis, display and printing of saccadic latency data. NB That the acquisition part requires specific hardware (The ViSaGe system from Cambridge Research Systems). Other methods of data input are under development, but OBE files may be imported via LatencyMeter from an Ober Saccadometer. In the most recent versions of SPIC this process can be highly automated: hundreds of OBE files can be analysed sequentially, creating and storing the derived reciprobit plots and copying the numerical results to the Log, which can exported as a spreadsheet or Word document.

Click here to download and install SPIC (18.vii.2014). Note that SPIC is now password-protected: please email me to be given a password. New features include improved automation of batch processing, faster simulation fitting, including simulation fits of two distributions at once, extended duration of experimental trials, further extension of the list of stimulus items, fitting of both express and inattention saccades, and the ability to read OBE files generated by recent upgrades to LatencyMeter. It also allows real-time recording using a saccadometer rather than an oculometer, via USB, but this feature has not yet been fully tested.

I will be happy to help with any problems you may encounter.
