1. Cognitive Level of Analysis

2. CLA Studies cognition All mental processes involved in attention, perception, memory decision making, problem solving and language. All the crap that goes on in your mind!!!

3. What is the Mind? They tend to look at the mind and an information-processing unit. Like a computer The brain is the hardware. The mind is the software.

4. The CLA is popular… About 70% of all therapists today draw from the cognitive school. I am going to make the argument that you are all cognitive therapists!!!

5. The Principles of…… The Cognitive Level of Analysis

6. Outline the principles that define the cognitive level of analysis and explain how they can be demonstrated in research.

7. Principle 1: Human beings are information processors and mental processes guide behavior. We are always trying to process the info around us. Our perceptions are usually based on what we already know. There is a relationship between our mental representation and the way we perceive and think about the world. What do you think this is? Outline the principles that define the cognitive level of analysis and explain how they can be demonstrated in research.

8. Principle 1 is demonstrated in Schema Theory A schema is a mental representation of knowledge in the brain. We have schemas for basically everything!!!! Right now in your head, picture a model. But does this one? Principle 1: Human beings are information processors and mental processes guide behavior.

9. Schema Theory They provide guidelines for interpreting information when trying to make sense of the world. They create expectations on what will happen in certain situations. Whether at religious school or at a party, you expect different behaviors. What if someone threw you a curve ball by doing something you do not expect. Principle 1: Human beings are information processors and mental processes guide behavior.

10. Schema Theory Can even explain…. Stereotyping – An overgeneralized belief about a group of people. Principle 1: Human beings are information processors and mental processes guide behavior.

11. Do schemas affect the way we perceive race? Principle 1: Human beings are information processors and mental processes guide behavior.

12. Schemas and Memory Reconstruction Our memories are not video and audio recordings. They are constructed by cognitive processes….like schemas. How do you think schemas can effect our memories? Principle 1: Human beings are information processors and mental processes guide behavior.

13. Schema Theory A Jean Piaget side note….. Assimilation Incorporating new concepts into existing schemas. If I teach my 3 year that an animal with 4 legs and a tail is a dog…. Accommodation Changing existing schemas to incorporate new information. What would he call this? If I tell someone from the mid-west to picture their schema of the Bronx they may talk about the ghetto areas. Principle 1: Human beings are information processors and mental processes guide behavior.

14. Darley and Gross (1983) Carried out a laboratory experiment on schema theory in the social world. Often called the Hannah Study Participants saw 2 videos of a girl. Principle 1: Human beings are information processors and mental processes guide behavior.

15. Darley and Gross (1983) In video 1, girl was playing in a poor environment. In video 2, girl was playing in a rich environment. Then they saw a video of the girl taking what looked to be an intelligence test and answering the questions inconsistently. Principle 1: Human beings are information processors and mental processes guide behavior.

16. Darley and Gross (1983) When participants were asked to judge the future of the girls, they all said the “rich” girl would do well and the “poor” girl would do less well. On average they judges the “rich” Hannah as having a 5 th grade academic level, and “poor” Hannah at a 4 th grade level. Principle 1: Human beings are information processors and mental processes guide behavior.

17. Darley and Gross (1983) The study demonstrates that participants probably used pre- stored schemas of what it means to be poor and rich. They then interpreted the rest of the scene based on these schemas. Principle 1: Human beings are information processors and mental processes guide behavior.

18. Principle 2: The mind can be studied scientifically. Cognitive psychologists use a wide array of methods to study the mind: Laboratory experiments Neuroimaging Case Studies Interviews Archival Research Outline the principles that define the cognitive level of analysis and explain how they can be demonstrated in research. Remember...behaviorists argued that thoughts cannot be measured

19. Principle 2 is demonstrated in Loftus and Palmer (1974) Reconstruction of Automobile Destruction Aim: To investigate whether the use of leading questions would affect recall in a situation where participants were asked to estimate speed. This is a situation that could happen when people appear in court as eyewitnesses. Principle 2: The mind can be studied scientifically.

20. Loftus and Palmer (1974) Reconstruction of Automobile Destruction Procedure: The student participants saw videos of traffic accidents and had to answer questions about the accident. Principle 2: The mind can be studied scientifically.

21. Loftus and Palmer (1974) Reconstruction of Automobile Destruction In experiment 1, the participants were asked to estimate speed of the cars based on a critical question: “About how fast were the cars going when they smashed/hit/collided/ bumped/ or contacted?” Principle 2: The mind can be studied scientifically.

22. Loftus and Palmer (1974) Reconstruction of Automobile Destruction Results: The mean estimates of speed were highest in the “smashed condition” (40.8 mph). Lowest in the “contacted group” (31.8 mph). Principle 2: The mind can be studied scientifically.

23. Loftus and Palmer (1974) Reconstruction of Automobile Destruction Results: Were the results just lucky? The p-value Anything p<.05 or less is significant. Which means there is a 5% chance the study is BS. The results in Loftus were significant at p<0.005 (.5% chance of that result occurring due to chance). The results indicate that memory is not reliable and can be manipulated by using specific words. Principle 2: The mind can be studied scientifically.

24. Loftus and Palmer (1974) Reconstruction of Automobile Destruction The critical word in question consistently affected the participants' answer to the question. One explanation could be that the use of different words influenced the participants’ mental representation of the accident…. i.e., the verb smashed activates a cognitive schema of a severe accident and therefore speed estimates increase. Principle 2: The mind can be studied scientifically.

25. Loftus and Palmer (1974) Reconstruction of Automobile Destruction It is not the actual details of the accident that are remembered but rather what is in line with a cognitive schema of a severe accident. Like reconstructive memory. Or maybe they just suck at estimating speed? Principle 2: The mind can be studied scientifically.

26. Loftus and Palmer (1974) Reconstruction of Automobile Destruction Evaluation: The experiment was conducted in a laboratory setting so maybe an ecological validity problem. Maybe too artificial. Use of just students as participants. But the controlled IV (words) and DV (speed) made it possible to establish cause/effect relationship. Principle 2: The mind can be studied scientifically.

27. Principle 3: Cognitive processes are influenced by social and cultural factors. Research has shown that cognitive processes such as perception, memory and thinking are influenced by socio cultural factors. Outline the principles that define the cognitive level of analysis and explain how they can be demonstrated in research.

28. Principle 3 is demonstrated in Bartlett (1932) “The War of Ghosts” Aim: To investigate whether people’s memory for a story is affected by previous knowledge (schemas) and the extent to which memory is reconstructive. Principle 3: Cognitive processes are influenced by social and cultural factors.

29. Bartlett (1932) “The War of Ghosts” Procedure: Bartlett asked British participants to listen to a story. After a while he asked them to reproduced (repeat) the story. He asked them again and again (over a period of months and years) which he called serial reproduction. Principle 3: Cognitive processes are influenced by social and cultural factors.

30. Bartlett (1932) “The War of Ghosts” The story was an unfamiliar Native American legend called “The War of Ghosts”. Principle 3: Cognitive processes are influenced by social and cultural factors.

31. The War of Ghosts One night two young men from Egulac went down to the river to hunt seals and while they were there it became foggy and calm. Then they heard war-cries, and they thought: "Maybe this is a war-party". They escaped to the shore, and hid behind a log. Now canoes came up, and they heard the noise of paddles, and saw one canoe coming up to them. There were five men in the canoe, and they said: "What do you think? We wish to take you along. We are going up the river to make war on the people." One of the young men said,"I have no arrows." "Arrows are in the canoe," they said. "I will not go along. I might be killed. My relatives do not know where I have gone. But you," he said, turning to the other, "may go with them." So one of the young men went, but the other returned home. And the warriors went on up the river to a town on the other side of Kalama. The people came down to the water and they began to fight, and many were killed. But presently the young man heard one of the warriors say, "Quick, let us go home: that Indian has been hit." Now he thought: "Oh, they are ghosts." He did not feel sick, but they said he had been shot. So the canoes went back to Egulac and the young man went ashore to his house and made a fire. And he told everybody and said: "Behold I accompanied the ghosts, and we went to fight. Many of our fellows were killed, and many of those who attacked us were killed. They said I was hit, and I did not feel sick." He told it all, and then he became quiet. When the sun rose he fell down. Something black came out of his mouth. His face became contorted. The people jumped up and cried. He was dead.

32. Bartlett (1932) “The War of Ghosts” Results: The participants remembered the main idea of the story (the gist) but they changed unfamiliar elements to make sense of the story by using terms more familiar to their own cultural expectations. Principle 3: Cognitive processes are influenced by social and cultural factors.

33. Bartlett (1932) “The War of Ghosts” The story remained a coherent whole although it was changed. It became noticeably shorter after each reproduction. Bartlett concluded that remembering is an active process. Memories are not copies of experience but rather “reconstructions”. Principle 3: Cognitive processes are influenced by social and cultural factors.

34. Bartlett (1932) “The War of Ghosts” Evaluation: The results of the study confirm schema theory (and reconstructive memory). But is was performed in a laboratory and might lack ecological validity. Principle 3: Cognitive processes are influenced by social and cultural factors.

35. Bartlett (1932) “The War of Ghosts” Participants did not receive standardized instructions and some of the memory distortions may be due to simple guessing (demand characteristics such as the Hawthorne effect) Still, this study is one of the most important in the study of memory. Principle 3: Cognitive processes are influenced by social and cultural factors.
