Question details

SAQ 3. Two Point Discrimination Threshold (TDP) Analysis: Analysis of TDP thresholds. Copy in all properly formatted values from your Table 2 and comment on your results. 

Part A. Please report your calculations of TPD thresholds for 'average increase', 'average decrease' and 'overall average', for each area of both volunteers. Your calculations should be reported to TWO digits after the decimal place (e.g., 13.02 mm). (0.5 marks)

AVERAGE INCREASE SUBJECT 1:

fingertip: 5.62mm

ventral forearm: 34.32mm

lower back: 38.00mm

AVERAGE DECREASE SUBJECT 1:

fingertip: 2.32mm

ventral forearm: 17.00mm

lower back: 34.82mm

OVERALL AVERAGE SUBJECT 1:

fingertip: 3.97mm

ventral forearm: 25.66mm

lower back: 36.41mm

AVERAGE INCREASE SUBJECT 2:

fingertip: 3.58mm

ventral forearm: 19.16mm

lower back: 60.00mm

AVERAGE DECREASE SUBJECT 2:

fingertip: 2.78mm

ventral forearm: 15.66mm

lower back: 43.00mm

OVERALL AVERAGE SUBJECT 2:

fingertip: 3.18mm

ventral forearm: 17.41mm

lower back: 51.50mm

QUESTION: Part B. Summarise your data and comment on how your average thresholds differed between areas and between volunteers. What is the neural basis for why some regions of the body (or some volunteers) had a lower TPD threshold (0.75 marks)?
