PEER ERP Paradigms for Comprehensive Research
PEER offers a comprehensive suite of ERP paradigms to allow researchers to study different aspects of cognitive processing. These include:
Visual Oddball: The traditional visual oddball task is available in three versions - no response, single response, and dual response - providing flexibility to tailor the task to your research question. The paradigm is designed to elicit the N200 and P300 ERP components, critical to cognitive and attentional processes.

Audio Oddball: Three versions of the audio oddball paradigm - no response, single response, and dual response - are also available to facilitate auditory cognitive research. The audio oddball task is used to evoke the N200 and P300 ERP components, crucial for auditory attention and processing.
Visual Go NoGo: The visual go nogo paradigm is the classic version of this task and is typically used to evoke the visual N200 ERP component indicative of cognitive control.
Auditory Go NoGo: The auditory go nogo paradigm is the classic version of this task and is typically used to evoke the auditory N200 ERP component indicative of cognitive control.
N-Back: The n-back task is a continuous performance task used to measure a part of working memory and working memory capacity.
Reward Gambling: The gambling, or doors, paradigm allows researchers to study reward processing and feedback-related negativity/reward positivity. Customization of the game enables the researcher to design the task in any desired manner.
Posner Cuing: The Posner game is a classic ERP paradigm used to study visuospatial attention. During the Posner task, researchers can present a cue that indicates whether a target will appear on the left or right side of the screen. Short after the cue, the target either appears where it was predicted to or on the opposite side of the screen. The point of the cue is to direct the participants attention to a possible target location and focus their attention there. Researchers can compare the evoked ERP response to valid and invalidly cued targets to study the P100 and N100 ERP components, both associated with the allocation of visuospatial attention.
Image Presenter: Allows the researcher to upload two series of their own selected images and will present them to participants. For example, if one wanted to study emotion, one series of images might evoke an emotional response (e.g. a cute puppy dog) whereas another series of images would not (e.g. a fork). By contrasting the evoked responses to the two categories of images a researcher would be able to gauge the amount of emotion in a response. Our unique Image Presenter allows the researcher to upload over 1000 images per category and control a wide range of image presentation features – image presentation time, image category randomization, response requirements, etc.
Raw Data Acquisition: With PEER you can record raw EEG data using the Raw Data Recorder. Simply push the record button to record raw EEG data from a device. Additionally, you can manually send event markers (1, 2, 3, 4) by pushing the corresponding buttons at the bottom of the PEER raw data recording screen. Files can be saved afterwards for offline analysis.
