for conducting computer-based research on attention, perception, and action control
we focus on the processing of tactile stimuli and the interaction of visual, auditory, and tactile senses
Lab equipment:
the laboratory consists of the experimental room and the control room for the experimenter
the experimental room is equipped with
broadband absorber plates (from 500 Hz 100% absorption) on the walls and a soundproof door (-30dB plus absorber values)
a sound-absorbing carpet and a sound-absorbing ceiling (absorption of all frequencies > 100 Hz)
a sound-absorbing curtain made of stage molton in front of the windows were glued with opaque foil and a black, sound-absorbing curtain made of stage molton was added
all walls, floor, ceiling and furniture being completely black to ensure external control over the stimuli that reach the sense of hearing and the sense of sight
The room complies with the fire protection standard B1.
the workplace for the participant is equipped with a computer workstation (Intel Core i7-2120 3.30GHz, 2x4GB RAM, 2x500GB HDD) and a 24" TFT monitor (16: 9 ) with calibrated Premium First Class Display for authentic color reproduction, which is digitally connected
Reaction times and error rates are measured using a Chronos (USB-based response and stimulus device), foot pedals, a voice key, or a joystick
Tactile stimuli are presented via an amplifier (Tangent AMP-50) or via a self-built control box with built-in controllable amplifier via small vibrators from Audiological Engineering Corporation (TACTAID VBW32) or Engineering Acoustics, Inc. (C2 Tactor)
the simultaneous processing of stimuli of two modalities can be controlled via covers, chin rest, arm mounts and accessories (headphones, earmuffs, visual-acoustic metronome)
with the help of a luminance meter (MAVO-Monitor USB, company Gossen) the luminance of visual stimuli can be measured and calibrated in cd/ m2
