New eye-tracking laboratory video and protocol!

 


 

EEG Laboratory

In psycholinguistics, we use EEG to measure event-related brain potentials (ERPs). An ERP is the measured brain response (amplitude in µV) to a specific stimulus (e.g., a word, or an object displayed on a computer screen) or a sequence of stimuli (e.g., several words in a sentence). By placing electrodes on the scalp, we can measure the stimulus-related electrical activity of the brain over time with high temporal resolution. ERPs are a non-invasive method and their high degree of temporal precision permits us to determine what functional cognitive processes are affected by a specific stimulus in real time.

 

 

 

 

 

 


 

Eye-tracking Laboratory

Modern eye-tracking technology permits us to measure a language user’s eye movements as they inspect images and listen to sentences or as they read sentences. From the gaze record we can gain insight into a language user’s locus of attention, but also into her expectations, difficulties, and response to contextual cues during language processing. Our laboratory has state-of-the-art eye-trackers (SR Research Eyelink 1000, SMI Red 300, Pupil Lab).

 

 

 

 

 

 

 

 


 

Reaction time measurements

Language processing and other cognitive tasks take time. It is postulated, that processes with higher cognitive demand also take longer time. We can measure, for example, how long it takes to process specific sentences or words. Participants are looking at a screen, from which they receive linguistic input - they are then asked to react to specific tasks by pressing buttons on a button box. While this sort of response is not continuous, it can nonetheless complement the eye-tracking and ERP data and enrich our insight into cognitive processes.

 

Computing infrastructure
  • We use state-of-the-art PC and Mac computers for preparing and analysing our eye-tracking and ERP data. Data storage is supported by HU file servers (check with Mr. Schliewe for precise naming). The infrastructure supports access to software (e.g., for audio- and video-file processing) and online corpora.
