Factors Affecting Perception and Motivation Study
Factors such as hunger can influence perception and motivation, as shown in the study by Gilchrist & Nesberg. Their research involved university students who went without food for 20 hours and were tested on how hunger affected their perception of brightness in images. The results indicated that motivation, in this case hunger, can alter how individuals perceive stimuli, suggesting a connection between motivation and perceptual set.

TITLE: Factors affecting perception motivation Monday, 22 July 2024 Last month Last week Last lesson What are the two types of praise? How do they help motivation? What is meant by the term emotion ? How does it affect our perceptual set? Describe the method that Gilchrist & Nesberg used in their study. Last year What are the ethical issues that psychologists might face when trying to study false memories? What are false memories? LO: To describe and explain Gilchrist & Nesberg s study of motivation.
Key term Perceptual set the tendency for our brain to notice some aspects of the environment more than others. To be set means to be fully prepared, anticipating what is coming so that we can act effectively Your motivation can influence what you pay attention to and what you ignore Motivation refers to the forces that drive our behaviour this can impact on our perceptual set LO: To describe and explain Gilchrist & Nesberg s study of motivation.
Perceptual set and motivation Aim: To investigate how motivation affects perception. Study design: Lab experiment. Method: -26 university students volunteered to go without food for 20 hours they could only drink water. - They were randomly allocated to one of two groups: one which went without food, and the other, a control group, which had normal meals during the 20 hours. - Participants show pictures on a screen for 15 seconds, then the screen would turn off, then they were told they would see the picture again, but they would not look the same. Their job was to adjust the brightness of the picture so that it looked the same as the one they had seen before. - They were tested at the beginning of the study (just after lunch), after 6hrs, and after 20 hours. LO: To describe and explain Gilchrist & Nesberg s study of motivation.
Perceptual set and motivation Results: Control group showed little difference in the memory of the brightness of the pictures as time went on. But as the experimental group became hungrier, they judged the pictures to be brighter. Conclusion: Hunger can affect the way that we perceive the images of food, which suggests that motivation affects perception. LO: To describe and explain Gilchrist & Nesberg s study of motivation.
