Thurstonian models have been used as an alternative to generalized linear models in analysis of sensory discrimination tasks.

However, Cohen et al. (1997) have proposed that, during their early years, blinded subjects develop a strong inclination for tactile discrimination tasks.

A discrimination task found significant alcohol-related impairments in depth perception and in visual short-term memory.

Within the group of autistic children, those who respond more globally to a discrimination task perform better on emotion and canine age tasks.

Cohen et al. (1997) proposed that in their early age, blinded subjects developed strong motivations to tactile discrimination tasks.

Nevertheless, rats can be trained to carry out visual discrimination tasks and will use visual cues to guide their natural behaviour.

As Cowey (1968) has pointed out, rats readily learn visual discrimination tasks when the contiguity between the stimulus, the response, and the reinforcement is high.

Deficits in spatial memory are also found in spatial discrimination tasks.

Further evidence for this theory was obtained by Bays and Husain (2008) using a discrimination task.

Manatees are capable of understanding discrimination tasks, and show signs of complex associated learning and advanced long term memory.
