chapter 8 Flashcards
Reflex
Certain behavioural response to certain stimulus
How can a reflex change through habituation ?
It can change as a result of repeated sequence of identical stimuli → the response of the
Central nervous system to the stimuli gets weaker by every sequence
How did Pavlov discover the conditioned response ?
Studied the reflexes involved in the canine digestion system. Discovery that dogs salivated differently to different winds of food. → some dogs salivated before receiving any foods. → response could be studied within the physiological realm.
How did he systematic the process of conditioning and what names did he give to thei relevant stimuli and responses?
Systematised the conditioning process by introducing a stimuli - a bell- along with the food given to the dog. Before, the bell was a neutral stimuli. Food was an unconditioned stimulus and salivation was an unconditioned response. After pairing, bell became conditioned stimulus and salivation became conditioned response.
How does the cognitive construct of expectancy help explain the ways in which conditioned responses differ from unconditioned responses?
Expectancy theory argues that subjects are conditioned to display certain behaviours which they seem suitable for the situation rather than blankly exhibiting a single trait to a conditioned stimuli. They mentally prepare them silver for the upcoming event by the behaviour displayed besides the conditioned response itself.
Three conditions in which the pairing of a new stimulus with an unconditioned stimulus does not result in classical conditioning?
① conditioned stimulus must precede the unconditioned stimulus for the subject to exhibit a conditioned response. ② conditioned stimulus must indicate the heightened probability of an unconditioned stimulus. ③ subject will not be conditioned if it already has a predictor that is superior to the new stimuhs. → animal has to learn that it can rely on the conditioned stimuli in order to expect the unconditioned stimuli
How did Watson demonstrate that the emotion of fear can be conditioned?
Little albert→ Albert was conditioned to expect a loud sound when ever a rat was placed in front of him; further pairings showed us that he was also terrified of other furry animals placed in front of him generalisations
Appetites effect and sudden craving for specific food beexplained in terms of classical conditioning?
Various sensory stimuli preceding food can condition us to feel hungry as a conditioned response to the same stimuli that have become conditioned stimuli.
Sexual arousal → conditioned in humans and other animals ? Evidence from experiments with nan human animals that such conditioning promotes success in reproduction
Various stimuli paired with sexual carousel have rendered subjects more readily available for copulation. -Male quails have been observed to have higher sperm count after being subjected to an unconditioned stimuli:
Why is conditioned response to a drug- related stimulus often the opposite of the direct effect of the drug?
Body gives a reflexive conditioned response to a drug-related. Stimuli to suppress the effects of the drug and turn the body to its normal state.
What is the westermarch effect, what evidence is there that it is based an early cohabitation?
Sexual aversion of genetic relatives or people that have been raised together. People that don’t have any genetic relations but are raised together often have no incidences of sexual attraction a intercourse; whereas people that have geneticrelations but are separated when they are very young and meet as adults often report a strong sexual attraction towards each other.

What is some evidence that people and monkeys are biologically predisposed to learn to fear some things more easily than other things?
Monkeys, raised in labs and never encountered a snake before initially do not exhibit any fearful reactions; however when they see another money react fearfully to a snake they immediately exhibit these fearful reactions too. This condition does not apply to safe er neutral objects. Humans (infants) exhibit more or less the same traits towards stimuli that evolutionarily been deemed dangerous or unsafe.
In sum what has natural selection imparted to young omnivores about food selection?
It would be safely to eat what the adults eat since they have probably eaten it before and they are still alive. Remembering the taste and smell of a food would be smart too since it can be associated with an increase or decrease in health and therefore be preferred or avoided
How do rats and pega he learn food preferences by attending to others of their kind?
By smelling each other’s mouth and preferring the food that has been eaten by the demonstrator. Humans, especially human infants, are much more likely to try a food if they have seen an adult try it first.
How has food-preference learning been demonstrated in humans?
When presented with a choice of foods from which one was rich in calories, many subjects initially enjoyed both equally; but l in the upcoming the day approval of calorie-rich food increased whereas that of the other either decreased or hasn’t changed.
