E-Prime: Sending triggers with task events

This is a question that pops by every now and then on the E-groups, pardon GoogleGroups, E-Prime mailinglist. How do you communicate with an EEG amplifier or other such equipment? In this short tutorial, I will explain how to use Task Events to send triggers via the parallel port. I will expect you to have at least E-Prime and an EEG amplifier that is connected via the parallel port (this includes BrainProducts and BioSemi equipment).

Always on my mind: A production-based course in EEG Acquisition & Analysis

This course was designed for my optional course at the Psychology Department of Liverpool Hope University (UK). Students learn the basics of EEG/ERP (brainwave) theory and data analysis with a goal to ‘read the mind of the subject and be able to tell who they are thinking of’. In weeks 1/2, they learn theory that suggests how they can do this (oddball experiments, the P3) and present their understanding using video tools (their phones’ cameras). In weeks 3-5, they get hands-on training in the lab so that they can record their own brainwave data (they film this process). In weeks 6-8, they […]

Ultimate Simon

  The ultimatum game is an economic decision making game in which people (responders) accept or reject fair and unfair offers from other people (proposers). The Simon task is a type of response conflict task in which people find it harder to act to one side if the stimulus happens to be on the other side (say respond right to something happening on the left). What could possibly relate economic bargaining and cognitive control?  

Cognitology in perception & action

Psychology and cognitive neuroscience traditionally show a tenacious  reoccupation with isolated functions and brain areas. We study memory, language, impulse control, the hippocampus, Wernicke’s area, and the anterior cingulate cortex. This analytical tradition has clearly proven its use: we can now answer a question like “how many numbers can a person keep in mind”, or “which brain areas work harder when more numbers are being stored in mind”. However, functions seldom operate in isolation: the reason someone keeps numbers in mind, rather than doing something else entirely, may be because we had them read instructions – requiring language – and […]
