Chapter 9 Focus Questions 1. What are the main components of the so called modal model of the mind? What is the purpose of such a model? Describe on an abstract level the general ways in which the mind processes info- operations by which the mind modifies, stores, and uses the input received through senses. The 3 types of memory stores and each is done by function, capacity, duration. The control processes govern the processing of info within stores and movement of info from one to another. 2. What is the function of sensory memory? It is to hold on to sensory info long enough for it be to thought of by unconscious mental processes and for a decision to be made about whether to bring it into working memory. 3. What are the functions of working memory, and how is it equated with consciousness? In what way is working memory like CPU in computer? This is the seat of conscious thought and holds all conscious perceiving and feeling. Unrehearsed info is quickly lost. Its like CPU in that info comes from both sensory and long term just as CPU gets info from keyboard and hard drive. 4. What is function of long-term memory and how is this memory different from working? Long-term memory is stored representation of all you know and things in there lie dormant until you need it for your short-term memory. Long term is passive, long duration and unlimited capacity whereas working is active, short duration, and limited capacity. 5. What are the functions of attention, encoding, and retrieval? Attention is controls info from sensory to working, and restricts flow from first to second because capacity of first is big to small. Encoding is from working to long term and not usually deliberate. Retrieval is from long term to working and called remembering. All three can be either deliberate or automatic. 6. What two competing needs are met by attention? How do concepts of preattentive processing and top-down control of attentive gate pertain to these needs? We have to focus on task at hand and not be distracted by irrelevant stimuli but when something in the stimuli signals benefits or danger that outweighs that task then we must pay attention to it. The preattentive processing is the gate in the middle of sensory and working, this gate sorts out what of the sensory info coming in, the body needs and is relevant unconsciously. It compares it to info in the working or long term memory which exerts its control thorough top down which tells the gate which stuff to allow inside the working at any time ( orders the info in the gate). 7. How have researchers shown that people very effectively screen out irrelevant sounds and sights when focusing on difficult perceptual tasks? Attention of selective listening is cocktail party when we screen out all other people’s voice except for the one person we are talking to even though other voices might be louder. When asked people to listen to two things and say one while other played, they couldn’t understand any of the second message. Selective viewing with the Rock and Guttman experiment, people
