Outline the conclusion of Gilchrist and Nesbergs motivation study
Gilchrist and Nesburg suggested that participants who we’re hungry had perceived the images of the food brighter than those who were not hungry. This is because they were more motivated to have the food which made the image brighter and more appealing in their heads.

Describe any ethical issues in Gilchrist & Nesberg’s motivation study
Physiological and physiological harm from the discomfort of not eating for 20 hours + deception as they thought they were doing a picture matching exercise
Give an example of an extraneous variable that could have affected the results in Gilchrist & Nesburg’s motivation study
Participants eyesight- regardless of whether they were starved or not, some participants may have had difficulty readjusting the brightness of the projector if they just had poor eyesight to begin with
Outline one strength of Gilchrist & Nesburg’s motivation study
Use of independent groups meant that participants could not see the other condition, which prevented them from guessing the true aim of the study, reducing demand characteristics
Outline one weakness of Gilchrist &Nesburg’s motivation study
Ethical issues of psych harm from not eating. Artificial-task that does not represent judgements made in the real world
Outline the aim of Bruner & Minturns expectation study
To investigate whether interpretation of an ambiguous figure is influenced by expectation
Outline the method of Bruner & Minturn’s expectation study
24 participants were shown the ambiguous figure of “13” in either a number sequence “121314”, or a letters sequence “A13C”. The participants then had to say & draw what they had seen .
Outline the results of Bruner & Minturn’s expectation study
Participants in the letters condition reported seeing “B” whereas the participants in the numbers condition reported seeing “13”. Participants were also more likely to draw the same figure in their own handwriting afterwards
Outline the conclusion of Bruner & Minturn’s expectation study
Participants used their past experiences of the alphabet or numbers to interpret an ambiguous figure
State the IV used in Bruner & Minturn’s expectation study
Whether the participants saw the ambiguous figure in a letters or number sequence
State the DV used in Bruner & Minturn’s expectation study
What the participants said they saw, and what they wrote down in their own handwriting
State the type of experiment used in Bruner & Minturn’s expectation study
Laboratory experiment
State the experimental design used in Bruner & Minturn’s expectation study
Independent groups
Give an example of an extraneous variable that could have affected the results in Bruner & Minturn’s expectation study
Participants eyesight- regardless of which sequence the participants saw, they could say/write down the wrong thing if they can’t see their sequence properly
Outline the strength of Bruner & Minturn’s expectation study
Highly controlled lan experiment by controlling how long they saw their sequence for // use of independent groups so they couldn’t see the same figure being used in 2 different sequences
Outline the weakness of Bruner & Minturn’s expectation study
Artificial task. ‘13’ was specifically designed to trick people - such tricks are not usually seen in mathematics or literature in the real world. Low external validity.
Name the 2 named studies in the perception topic
Gilchrist & Nesburg and Bruner & Minturn’s
What is sensation?
Sensation is the information we receive through our senses from the environment. It is the objective feeling of stimuli.
What is perception?
Perception is the subjective interpretation and organization of sensory information by the brain. It is personal and based on past experiences.
What is an example of perception affecting recognition?
Face Blindness is an example where people have the same sensations when looking at a face, but some cannot recognize the facial features due to perceptual difficulties.
