    1. But the recent development of psychological studies of young children and the growing tendency to carry the knowledge gained in the psychological laboratories into the home and school induce us to predict a more wholesome treatment of a future generation of Peters.

      In summary, this particular case study provided evidence or provided information that would fall under various fields and subfields of psychology today. Various aspects in life were mentioned and referred to such as environmental experiences (physical environment and home environment), social experiences, physiological experiences, and emotional experiences. It was an amazing read and interesting to see how many different areas of psychology were present in a study that seemed very behaviorism-based at first.

    2. From reading over the notes for each session it was apparent that there had been improvement by more or less regular steps from almost complete terror at sight of the rabbit to a completely positive response with no signs of disturbance. New situations requiring closer contact with the rabbit had been gradually introduced and the degree to which these situations were avoided, tolerated, or welcomed, at each experimental session, gave the measure of improvement. Analysis of the notes on Peter's reactions indicated the following progressive steps in his degrees of toleration:

      This reminds me of systematic desensitization, wherein, an individual is presented with and exposed to different levels of anxiety-/fear-eliciting stimuli, all while being taught relaxation techniques. The procedures and steps taken to get Peter to accept the rabbit is through gradual exposure. This definitely contributed to the literature of clinical psychology in the treatment of phobias.

    3. Peter and three other children were brought to the laboratory for a play period. The other children were selected carefully because of their entirely fearless attitude toward the rabbit and because of their satisfactory adjustments in general. The rabbit was always present during a part of the play period.

      The fact that they had three children who had not feared the rabbit in the same room with Peter, all while the rabbit is present as well, makes me think even more about social learning theory. Although it does make me pose the questions: "was Albert distracted by playing with others?" "Did he find comfort in outnumbering the 'threat?'" "How were his initial reactions? Did he have to warm up to playing after observing the other children not showing signs of fear when near the rabbit?"

    4. From the test situations which were used to reveal fears, it was found that Peter showed even more marked fear responses to the rabbit than to the rat.

      The similarity to Albert is uncanny here it seems, although I do wonder, and I am not sure if I remember whether the intensity of Albert's fearful reactions to the bunny were the same as those elicited when in the presence of a similar animal.

    5. This case made it possible for the experiment to continue where Dr. Watson had left off. The first problem was that of "unconditioning" a fear response to an animal, and the second, that of determining whether unconditioning to one stimulus spreads without further training to other stimuli.

      The coincidence and convenience provided by it, allow for further questions to be provided some answers, and to continue off Watson's particular case. It is interesting, to me, because this is the first time I have heard of this experiment, which is a continuation of sorts of the work made by Watson. Anyways, it gave the opportunity to demonstrate whether conditioning could be used to get rid of a maladaptive response to a given and/or similar stimuli.

    6. By referring to the chart at (b), it will be noted that the line shows a decided drop to the early level of fear reaction when he returned. This was easily explained by the nurse who brought Peter from the hospital. As they were entering a taxi at the door of the hospital, a large dog, running past, jumped at them. Both Peter and the nurse were very much frightened, Peter so much that he lay in the taxi pale and quiet, and the nurse debated whether or not to return him to the hospital. This seemed reason enough for his precipitate descent back to the original fear level. Being threatened by a large dog when ill, and in a strange place and being with an adult who also showed fear, was a terrifying situation against which our training could not have fortified him.

      It could not have been helped that Peter developed fear again due to this unique situation with contributing factors. He was exposed to an abrupt fear-eliciting stimuli, which in comparison to his gradual exposure stages, was a huge jump from where he at in the lab. Along with his negative physiological experiences and observation of an adult being afraid reinforced his fear again. Also the strange environment provided no solace either. This particular circumstance gives an early example of converging factors providing explanation to a particular outcome. Real life is multivariate and this is an example of it.

    7. Through the presence of the pleasant stimulus (food) whenever the rabbit was shown, the fear was eliminated gradually in favor of a positive response. Occasionally also, other children were brought in to help with the "unconditioning." These facts are of interest in following the charted progress. The first decided rise at (c) was due to the presence of another child who influenced Peter's reaction. The notes for this day read: Lawrence and Peter sitting near together in their high chairs eating candy. Rabbit in cage put down 12 feet away. Peter began to cry. Lawrence said, "Oh, rabbit." Clambered down, ran over and looked in the cage at him. Peter followed close and watched.

      Yet another example demonstrating the collaborative work between social factors and the positive conditioned response Peter has.

    8. Barbara was brought to the crib and the white rat introduced as before. She exhibited no fear but picked the rat up in her hand. Peter sat quietly watching Barbara and the rat.

      This reminds me of Albert Bandura's Social Learning Theory, he is watching another person interact with the object that terrifies him, and yet the other person does not seem to share the same fear response as him. He watched Barbara pick up the rat, which conveys the message that others don't fear it, and it does not seem to do any harm. Although the observation of this, I do not believe, would be enough to provide change in his conditioned response, as it had most likely been with him for a while. One thing I am wondering based on this certain situation is if he felt less afraid due to the distance between him and the rat or because another person is holding the rat, which in turn might provide a sense of security that the threat has been detained.

    9. The next two decided rises at (d) and (e) occurred on the day when a student assistant, Dr. S., was present. Peter was very fond of Dr. S. whom he insisted was his "papa." Although Dr. S. did not directly influence Peter by any overt suggestions, it may be that having him there contributed to Peter's general feeling of well being and thus indirectly affected his reactions.

      I wonder why Peter was very fond of Dr. S? What did Dr. S do in order for Peter to be very fond of him, did he resemble his father? The suggestion that Dr. S's presence in the room alone contributed to Peter's well-being reminds me of Applied Behavior Analysis. ABA operates off the principles of operant conditioning which is usually taught along with classical conditioning in today's intro to psychology courses. Anyways, when ABA is used to help children who have autism in learning adaptive behavior, a good relationship between the provider and the child must be established before direct intervention can take place. The child and the provider gain their relationship through unstructured and eventually structured play. The child then associates the provider with good things and in turn allows for easier reception of a given intervention. If Dr. S did something similar with Peter, then it provides some early evidence of reinforcement pairing (i.e., when the provider themselves have become a reinforcing factor for the child).

    10. Peter was 2 years and 10 months old when we began to study him. He was afraid of a white rat, and this fear extended to a rabbit, a fur coat, a feather, cotton wool, etc., but not to wooden blocks and similar toys. An abridgment of the first laboratory notes on Peter reads as follows:

      How odd and quite coincidental that Dr. Jones would have encountered a case almost the same to that of little Albert. It makes me wonder and poser the question, "How did Peter develop his phobia?"

    11. The fear of the cotton, the fur coat, feathers, was entirely absent at our last interview. He looked at them, handled them, and immediately turned to something which interested him more. The reaction to the rats, and the fur rug with the stuffed head was greatly modified and improved. While he did not show the fondness for these that was apparent with the rabbit, he had made a fair adjustment. For example, Peter would pick up the tin box containing frogs or rats and carry it around the room. When requested, he picked up the fur rug and carried it to the experimenter.

      These results from their interview answers their initial question on whether further conditioning measures would need to be taken on the fear that he experienced with other similar objects. Due to him not demonstrating signs of fear, the researchers can be confident that Peter does not need further conditioning measures for the other similar stimuli. It also showed that Peter's feelings of positive affect for the rabbit was not generalized to the other similar objects, which had been the initial case with his fear. This case was able to expand on Watson's and answer questions that Watson was unable to due to Albert not being involved in his study any longer.

    12. In referring to this case, Dr. Watson says, "We have shown experimentally that when you condition a child to show fear of an animal, this fear transfers or spreads in such a way that without separate conditioning he becomes afraid of many animals. If you take any one of these objects producing fear and uncondition, will fear of the other objects in the series disappear at the same time? That is, will the unconditioning spread without further training to other stimuli?"

      Watson also demonstrated how their conditioned behavior could be generalized to other similar stimuli, further contributing to the body of literature of behavioral psychology.

    13. What would Peter do if confronted by a strange animal? At the last interview the experimenter presented a mouse and a tangled mass of angleworms. At first sight, Peter showed slight distress reactions and moved away, but before the period was over he was carrying the worms about and watching the mouse with undisturbed interest. By "unconditioning" Peter to the rabbit, he has apparently been helped to overcome many superfluous fears, some completely, some to a less degree. His tolerance of strange animals and unfamiliar situations has apparently increased. [p. 315]

      The last sentences describing how his tolerance to strange animals and unfamiliar situations have seemed to increase make me think of resilience. Peter was in a good environment that helped him foster his resilience toward fear-eliciting stimuli. Each slight exposure challenged his resilience and with the help of others, he was able to overcome them. Although I may be overstretching things here a little bit by suggesting this.

    14. The study is still incomplete. Peter's fear of the animals which were shown him was probably not a directly conditioned fear. It is unlikely that he had ever had any experience with white rats, for example. Where the fear originated and with what stimulus, is not known. Nor is it known what Peter would do if he were again confronted with the original fear situation. All of the fears which were "unconditioned" were transferred fears, and it has not yet been learned whether or not the primary fear can be eliminated by training the transfers.

      The issue that distinguishes him from Albert is that it is not known exactly how Peter developed his fear. Albert was conditioned to have his fear, and there might be other explanations for Peter's fear. Also the investigator posed a really important question, which undoubtedly led to its investigation later one, the question was in regard to whether intervention taken against other similar fear-eliciting stimuli would end up transferring to the primary fear.

    15. A brief review follows: Albert, eleven months [p. 309] of age, was an infant with a phlegmatic disposition, afraid of nothing "under the sun" except a loud sound made by striking a steel bar. This made him cry. By striking the bar at the same time that Albert touched a white rat, the fear was transferred to the white rat. After seven combined stimulations, rat and sound, Albert not only became greatly disturbed at the sight of a rat, but this fear had spread to include a white rabbit, cotton wool, a fur coat, and the experimenter's hair. It did not transfer to his wooden blocks and other objects very dissimilar to the rat.

      The experiment on little Albert, one of the most memorable that I have learned throughout the course of my academic career in psychology. I remember how in awe I was when first learning about it and how incredible it seemed and yet so cruel at the same time. This along with Pavlov's study on dogs demonstrated the capabilities of classical conditioning, as well as how living things can be conditioned to elicit responses when in the presence of a given stimuli. Although, Watson's experiment on little Albert showed how humans could also be classically conditioned. Today it is also, among various other studies in the past, used as an example when discussing the ethics of psychology. Obviously in today's era this study would not be granted the approval by the Institutional Review Board.

    16. Peter's I.Q. at the age of 2 years and 10 months was 102 on the Kuhlmann Revision of the Binet. At the same time he passed 5 of the 3 year tests on the Stanford Revision.

      The fact that Peter's IQ was tested using more than one psychometric measuring intelligence, reflects the desire for the application of psychology at the time. It also provided the comparability to others sharing a similar age to Peter's which helps rule out that his fear may be due to lower intelligence.

    17. As part of a genetic study of emotions[1], a number of children were observed in order to determine the most effective methods of removing fear responses.

      This opening sentence suggests that the work contributes to "nature vs. nurture" debate. A debate that has been posed by many psychologists in the past and is still brought up to this day.

    18. Another matter which must be left to speculation is the future welfare of the subject. His "home" consists of one furnished room which is occupied by his mother and father, a brother of nine years and himself. Since the death of an older sister, he is the recipient of most of the unwise affection of his parents. His brother appears to bear him a grudge because of this favoritism, as might be expected. Peter hears continually, "Ben is so bad and so dumb, but Peter is so good and so smart!" His mother is a highly emotional individual who can not get through an interview, however brief, without a display of tears. She is totally incapable of providing a home on the $25 a week which her husband steadily earns. In an attempt to control Peter she resorts to frequent fear suggestions. "Come in Peter, some one wants to steal you." To her erratic resorts to discipline, Peter reacts with temper tantrums. He was denied a summer in the country because his father "forgets he's tired when he has Peter around." Surely a discouraging outlook for Peter.

      His familial experiences seem to suggest that they played a role in him developing his fear, although it is hard to discern whether this was a direct cause. I would say that it is indirect. I feel like his experiences in the home made him psychologically vulnerable to experiencing fear, since his was given the impression that danger was all around. This illustrates that the home-environment might have been one factor of many that contributed to Peter's fear.
