Research Facilities

To facilitate high quality teaching and research, the Department maintains several state-of-the-art psychological laboratories. They are equipped with modern facilities for sensation and perception, cognitive psychology, developmental psychology, social psychology, personality, human factors, industrial-organizational psychology, neuropsychology and animal research.

ASL 504 Remote Eye Tracker with Magnetic Head Tracking

The ASL 504 Remote Eye Tracker with Magnetic Head Tracking is a bright-pupil system that ASL504RemoteEyeTracker 2tracks gaze by sending an illumination from the remote unit to the left pupil of the participant. We have been using the eye tracker to examine how age and personality variables influence attention for emotional and non-emotional stimuli. This is the only system that can combine the magnetic head tracker with the pan tilt to virtually eliminate the need to reacquire the eye during motion or correct for point of gaze errors. It allows the participant approximately one square foot of head movement which eliminates the need for head restraint. It records gaze location 60 times per second, and calculates gaze position by following both the position of the pupil and corneal reflection.

NeuroScan 64 Channel

NeuroScan64 sThe whole system consists of 64 channel SynAmp, a fast track digitizer, Stim input system, and an alternative E-prime system. The system is used for the collection of the EEG activities in various cognitive processes, which can help in the study of the brain synchronization, subliminal perception and will be used in information processing in sleep.

ISS Imagent™

It provides a balance between temporal and spatial resolution for the cognitive study of superficially located areas of human brain by addressing two main applications techniques:

Functional Near Infrared Spectroscopy (fNIRS), which detects changes in the absorption of the optical signal in response to a stimulus and provides a map of the areas where the changes occur. The changes in the optical signal (time scale > 100 ms), are due to local variations of oxy- and deoxy-hemoglobin concentrations.

Event Related Optical Signal (EROS), which detects changes in the scattered component of the diffuse signal subsequent to a stimulus. The changes (time scale < 100 ms) are due to the variation in the shape of the glia and neurons and/or in the optical properties of the membrane.ISSImagent soptical participant s

Magnetic and Electric stimulation systems TMS and tD/ACS & Neuronavigation System

Magnetic and Electric stimulation systems TMS and tD/ACS

Brain stimulation  makes use of electromagnetic induction principles to produce a local current in the cerebral cortex.  By using magnetic fields in Transcranial Magnetic Stimulation (TMS) or electric currents in transcranial direct/alternate current stimulation (tD/ACS), brain activities can be modulated directly.

Neuronavigation system

Neuronavigation systems enable accurate planning, targeting and monitoring for brain stimulation studies using TMS and tDCS. They can also be used for 3D localisation of Neuroimaging systems such as EEG and NIRS.  TMS 2 s

 

EGI Geodesic EEG System 400

The Lifespan Development Laboratory is equipped with the EGI Geodesic EEG System 400. The maximum acquisition rate is at 1000Hz. The system supports up to 256 channels sensor net (The lab equipped with 128 channels sensor nets). The Ag/AgCl sensors use saline solution as conducting medium. The net application time is relatively short (around 10 minutes) as compared to gel type system. This system also comes with Net Station 5 software suite, basic preprocessing and visualization can be done efficiently. We used this system to study the brain response to word processing on children twins. The stimuli presentation was controlled by E-prime 2.0.
