Question

According to Stevens, increasing pain stimuli causes a(n) change in sensation ie, exponential linear logarithmic O inverse QUESTION 18 John is taking part in a Psychology Department experiment He is shown a piece of string 10" long According to Weber, in order for John to notice a difference in length, a second string will have to belonger or shorter than the first one 01 001 QUESTION 19 Jeanine is working on a psychology experiment looking at auditory absolute thresholds by using the method of limits She has found that participants identify stimuli at diflerent levels depending on whether she is adjusting the sounds up or down She has decided to let the participants do the adjustments instead What should she call this new technique? Method of adjustment O The lazy way O Particpant empowerment O Method of limits

Explanation / Answer

ANSWER 17: Exponential

Because, the increase in stimuli shortens the pain threshold timing which is reached sooner. This leads to increase in pain sensitivity and the perceived pain. Therefore the person experiences an exponential change in pain sensation when the stimuli are increased.

ANSWER 18: 1"

This is because Weber's law states that an observable change is noticed only if the ratio of change in increment and the original length is constant for example 0.1 where the difference threshold changes linearly.

This can only be possible if the string is made 1 inch longer or shorter.

ANSWER 19: Method of adjustment

This is because the sound is adjusted to find its effect by the average crossing over of the points
