Figure 1: Average Measurement of Two-Point Discrimination: (SHORT DISCRIPTIONS OF THE GRAPH) E.G. The right side generally have higher average of two-point discrimination (right palm: M = 12; SD = 1.41) than the left side (left palm: M=10; SD = 1.63)…
Must mention results in discussion and make comparisons between means of right and left sides: M = mean, SD = Standard deviation, P = p-value (table does not need to be included in the report)
Right side
finger (M = 3; SD = 0.82), p > (0.05) – sig
palm (M = 12; SD = 1.41), p > (0.05) – sig
calf (M = 47.25; SD = 6.08), p > (0.05) – sig
forearm (M = 27.75; SD = 7.93), ), p > (0.05) – sig
Left side
finger (M = 3.5; SD = 0.58), p > (0.05) – sig
palm (M = 10; SD = 1.63), p > (0.05) – sig
calf (M = 33.75; SD = 6.24), p > (0.05) – sig
forearm (M = 24; SD = 13.69), p > (0.05) – sig
P > (0.05) = significant – there was a difference
P < (0.05) = not significant – no difference
T-test : compare means of each conditions (left and right fingers mean ) at least one t-test

Must mention results in discussion and make comparisons between means of right and left sides: M = mean, SD = Standard deviation, P = p-value (table does not need to be included in the report)
Figure 3: Number of Thermoreceptors in Forearm and Forefinger(SHORT DISCRIPTIONS OF THE GRAPH) Compare two conditions where the forearm and forefinger was exposed and compare the results of the forearm to the forefinger.
Discussion: (Write in paragraphs answering the questions)
Part A:
Do your results support the contention that ‘peripheral regions’ most sensitive to various types of tactile stimulation have the largest cortical representation? Discuss in reference to your own groups results as well as comparison to class mean averages and any previous scientific literature. (REFER TO HOMUNCULUS – Sensory representation literatures)
What neurophysiological mechanisms are responsible for the variations in two-point discrimination?
Part B:
Why is the error of localisation of touch less in one area of body compared to other areas?
(receptive field size: provides precise information on location or not – best discrimination/localisation in regions with HIGH DENSITY of small receptive fields) – Can refer to Prac 2 Sensory Receptive Field Sensitivity Doc
Part C:
Are thermal receptors ‘rapidly or slowly adapting receptors’? Explain the basis for your answer. (Slow adapting – elaborate)
Discuss the spatial discrimination of thermal receptors. (Include literature – how many cold;hot receptors ratio is usually found across body.
