Perzeptuelles Diskriminationslernen

Perceptual learning yields relatively permanent improvement of the discrimination capabilities of human observers. We especially focus the formation of sensory coding pathways due to discrimination training. Observations indicating that sensory mechanisms with new, training specific coding behaviour have evolved are

1. Change of psychophysical tuning functions obtained before and after discrimination training
2. Task and stimulus specific schemes of learning transfer observed after training and
3. Differential improvement of coding efficiency for the trained set of conditions Experiments are designed to contribute to these questions using a variety of spatial frequency discrimination, orientation discrimination and texture discrimination tasks.
