Click here to experience some stimuli roughly like those used by Joetta Gobell and Marisa Carrasco*, but presented for rather longer (approximately 100ms here; 40ms in the experiments).
You’ll need either OpenOffice Impress or Microsoft PowerPoint. I’m afraid the timing may not work properly on some older versions.
The paper in which I discuss these stimuli is currently under review. Please get in touch if you’d like to read it.
Disclaimer: These stimuli are inappropriate for any rigorous experiment. They are intended only to give you a general sense of the experience of relevant briefly presented stimuli.
