Behavioural Labs

The CBE behavioural labs are comprised of two distinct labs and offer state-of-the-art hardware and software to conduct high-quality research. 

You can also contact us for further information.

Multi-Purpose Lab

Multi-purpose lab

The Multi-Purpose Lab can be used for experimental and non-experimental research. It can also be used for teaching when it is not being used for research purposes.

It hosts 18 workstations for participants and one workstation for the researcher. The workstations are networked in a client-server model and have Internet access. The researcher can start and stop the Internet access to the client computers using the server computer. The workstations can be partitioned by removable screens. The tables in Multi-Purpose Lab can be reconfigured for work groups, classroom settings, or focus group discussions. Such capability enables researchers to conduct studies that involve problem solving in multidisciplinary teams as well as group experiments. The Lab is also fitted with audiovisual equipment that can be used by the researcher for presentations. 

Advanced-Equipment Lab

Advanced equipment lab

The Advanced-Equipment Lab hosts one sound proof booth and two workstations. The sound proof booth is completely climatized; the temperature as well as lighting inside the booth can be controlled by the researcher. The booth hosts state-of-the-art devices such as an eye tracker, skin conductance (e.g., GSR), heart rate (e.g., ECG) and facial expressions measuring devices. It is also fitted with an advanced stimulation tracking device (e.g., StimTracker) that helps synchronize eye tracker and ECG/GSR data.

Hardware

The Advanced-Equipment Lab is fitted with the following hardware:

Tobii Eye Tracker ▼

Tobii TX300 eye tracker allows large head movements and collects data at 300 Hz. The system is designed for studies that require a higher sampling rate; e.g. the need to study eye movements such as saccades, fixations, pupil size changes and blinks. The unique combination of a higher sampling rate and large head movement box benefits eye tracking studies where freedom of movement is important.

Electrocardiography (ECG) & Galvanic Skin Response (GSR) ▼

We are using BiosignalsPlux Researchers’ Kit that includes sensors to measure heart rate and skin conductance response. It allows to collect data upto 1000Hz. The higher sampling rate allows researchers to get high number of data points per second. We have synchronized ECG and GSR sensors using Stim Tracker with eye tracker data. Such synchronization enables researchers to precisely identify physiological responses (e.g., GSR and ECG) related to specific events as well as eye fixations. 

StimTracker ▼

StimTracker allows including markers to data collected through eye tracker and skin conductance and heart rate measuring devices. The inclusion of markers to data helps researchers identify precisely when certain events occurred. Except for codes sent via USB, the onset of events is detected autonomously by STIMTracker, allowing it to avoid delays incurred by operating systems and produce accurate markers.

It offers several ways to track stimuli. That include:

  • Onset of Visual Stimuli. Use the included fast light sensors to avoid operating system delays and detect onset of visual stimuli with precision.
  • Onset of Participant Response.
  • Onset of Vocal Response.
  • Onset of Auditory Stimuli. Simply pass the audio output via STIMTracker, set the threshold, and let it do the rest.
  • Event Codes via USB. Researchers can also send event codes from stimulus presentation computer using USB for added information.

Software

Our labs are fitted with several software used for behavioural research.

Tobii Studio for Eye Tracking Data ▼

Tobii Studio is offered by Tobii and allows researchers design and run eye tracking experiments. It also allows replaying and visualising the results, and calculating statistics.

Design: It provides intuitive tools to design experiments and present stimuli.

Record: It allows synchronizing eye tracking data with a wide range of other data to get holistic view of participants’ behaviour.

Observe: It also allows remote observation of data collected in real time which in turn gives insights into participants' real time behaviour and experience.

Replay: It allows researchers to replay eye tracking sessions for in-depth analysis.

Visualisation: It also provides graphical representations of data such as heat maps and gaze plots.

Statistics: It allows researchers to perform statistics intuitively, develop click metrics, and flexible tables and charts.

Noldus FaceReader ▼

Noldus FaceReader automatically analyses basic facial expressions for emotions including neutral and the emotion of contempt. It also provides data related to participants’ characteristics, head orientation and eye gaze direction.

The software allows analysis as well as reporting.

Balloon Analogue Risk Task (BART) ▼

The Balloon Analogue Risk Task (BART) allows to measure risk taking behaviour. It is based on reward versus loss model. The participants are presented with a balloon and offered the chance of earning money by pumping up the balloon by clicking a button. Each click inflates the balloon and money is added to the participants’ account until some threshold is reached, at which point the balloon explodes. Therefore, each pump results in earning the participants money, but at the same time causing increasing risk. 

Z- Tree ▼

z-Tree is a software package used for developing and carrying out economic experiments. Researchers can develop experiments in z- Tree without having programming experience.

The z-Tree software is implemented as a client-server application. The server side application is called z- Tree and the client side application is called z- Leaf.
