Nt1310 Unit 4 Lab Report
CHAPTER 4
Objectives:
1. Define consciousness.---------
2. Appreciate the role of the circadian rhythm.
3. Describe the stages (5) of sleep including the sequence of the stages.
The development of the electroencephalograph led to dramatic increases in what is known about sleep. When electrodes are attached to the face and scalp of sleepers, different patterns are produced on the graphic record called the electroencephalogram or EEG. The patterns vary in frequency and amplitude of the waves shown on the EEG. These waves reflect patterns of brain activity. It was discovered that the patterns on the EEG change throughout the night to correspond to various stages of sleep.
Wakefulness is characterized by beta waves and relaxation is characterized by …show more content…
Operant Conditioning
The bell rings at school and children on the playground line up to enter the school building. Children who line up in an orderly fashion are rewarded for their behavior.
In this example of operant conditioning, the bell is a signal, or (5) discriminative stimulus, that sets the occasion for the response/behavior of getting in line.
For Christmas, Paula receives a new bicycle. Paula’s father teaches her to ride it by first having her sit on the bike while he pushes it, and then having Paula pedal while he pushes. Finally, Paula pedals on her own while he runs along side her. What technique in operant conditioning is Paula’s father using to teach her to ride her bike? (6) shaping
Steve always puts money in the vending machine outside his psychology class to purchase a cup of coffee. The machine has always functioned, i.e., he has been continuously reinforced for putting in his money. One morning, Steve puts in his money but does not receive his coffee. Therefore, Steve stops putting money in the vending machine. This is an example of which process in operant conditioning? (7)
