The research studies have also shown that there is a discrepancy between the data obtained from 2PD tests and data obtained from other tests used to measure tactile spatial acuity. [19] 2-point orientation discrimination (2POD) compared to traditional two-point discrimination (2PD)
Sensory analysis (or sensory evaluation) is a scientific discipline that applies principles of experimental design and statistical analysis to the use of human senses (sight, smell, taste, touch and hearing) for the purposes of evaluating consumer products. This method of testing products is generally used during the marketing and advertising ...
