Describe Harlow's study?

- Monkeys were reared by wire "mothers". One mother was covered with a soft cloth, the other was not. Monkeys clung to the soft cloth mother and rejected the wire mother, even when the wire mother provided all the food. This is evidence that "contact" comfort is necessary for attachment. - Other monkeys were reared for the first 6 months of their life with no contact at all (social deprivation). Even though they were exposed to normal parenting after the 6 months, the monkeys showed severely abnormal social behavior throughout their lives. They made terrible mates and parents (some even killed their infants). This is evidence of the importance of an early attachment relationship.

Manifest Content: Man dreams that he is a gladiator. He carries a sword. He is searching for something. He sees a large golden egg. He wants the egg. He tries to get it. He runs forward bearing his sword. He chases the egg as it rolls away from him. He is angry and frustrated. Latent Content: The gladiator represents his power/manhood. The sword represents his penis. The egg represents his mother's womb and his desire to return to the safety of the womb. Egg may also represent unresolved sexual feelings he has towards his mother. He is angry because he cannot express these sexual desires and he cannot return to the womb.

Give an example of sensory adaptation

• Example: when you jump into cold water at first you feel freezing, but after a few moments, the water does not feel as cold (sensory receptors are fatigued and do not detect the stimulus as strong as they first did) ANOTHER EXAMPLE: -When we leave the radio on in our car after we park it at home for the night -When we listen to the radio on the way home from work the volume seems reasonable - However, the next morning when we start the car, we might be startled by how loud the radio is (we don't remember it being that loud last night) -What happened is that we adapted to the constant stimulus of the radio volume over the course of the previous day-this required us to continue to turn up the volume of the radio to combat the constantly decreasing sensitivity -However, after a number of hours away from that constant stimulus, the volume that was once reasonable is entirely too loud, we are no longer adapted to that stimulus.
