The Halo effect experiment by Solomon Asch

This experiment is a classic study in the psychology of interpersonal perception, these series of experiments were titled Forming Impressions of Personality by Solomon Asch, the principle of this research is that perceptions of a person are by the traits they posses, these perceptions are the most important factor that help our mind establish an impression on that person. The halo effect experiments conducted by Solomon Asch were many, he did various experiments but generally following the same outline, the only changing variable were the order of the words dictated to the series of participants, serie A and serie B, he used many words who were the same but they were put in the inverse order between serie a and b, in such as participants from serie A got the serie A description and serie B the B description, these descriptions were full of words who were the same in each set but put backwards, being the independent variable, then the experimentors procceded to ask the participants from series A and B for a sketch from the details provided, the sketch the participants drew is the dependent variable, since it is the one that is measured according to what the participant drew relating it to the words provided by the experimenter, the sketches showed what the experimentors were expecting to see, although the descriptions contained NO physical characteritics like "tall" only descrptions such as "intelligent", the participants responded with a positive sketch of the described person to the description with positive attributes at the beginning, and on the otherhand they responded with a negative sketch such as an ugly person to the description that contained bad attributes at the beginning, this showing how simple words that represent no physical description can make up an image about a person, and how the association of the human mind is so strong, vinculating people who are considered attractive with positive characteristics and vice versa, people not considered attractive with negative characteristics. The person described by the participants in serie A were always related to someone they knew, with a profession they had in their mind containing those characteristics, such as being "intelligent", related to a teacher, a scientist, etc. There were many parts to this experiment, alternating the words so the outcome was more precise, I would like to recreate the one where it gave the traits of "A. intelligent—skillful—industrious—determined— practical—cautious—evasive B. evasive—cautious—practical—determined—industrious—skillful—intelligent"

Cultural Differences

The childhood amnesia between cultures such as Korean, New Zealander and American person differences in the age, such as Koreans at 4 years old, New Zealanders at 2.5, and Americans generally at 3.5 years old, researchers have found that in average age of first memories, it varies between the ages of two years between different cultures. This is due to the culture the child is raised in and the customs their parents have, since if the parents discuss it or don’t discuss the events in the child’s life the better or the worse the child will remember these events, and the societies vary in the way they talk about their children, making it easier or harder for the child to remember the events of his or her childhood. The more the independent the customs and the country the harder it will be for it to remember earlier childhood events and the more countries that focus on individual personal history have earlier childhood memories.

Sex Difference in Memory: Women better than Men at Remembering Everyday Events

The studies done by these people showed that there is a difference in the episodic memory between the two sexes, and these studies favored women. The studies showed that women excel in verbal episodic memory tasks, like remembering objects, pictures and words, and on the other hand men outperform the opposite sex when remembering things with symbolic meaning, non-linguistic information, and known as visuospatial processing.

Placebo

The Placebo effect is a measurable, observable or felt improvement in health or behavior not attributable to a medication or invasive treatment that has been administered, in other words its an inert substance that produces the same or a similar effect as an actual medicine. H.K. evaluated 15 clinics and here he found that 35% of the 1082 treated patients were actually relieved and cured by a placebo, showing the inmense power of placebos. The problems this had were found by Kienle and Kiene and they found that in a reanalysis "no evidence of any placebo effect in any of the studies cited by him." The effect of placebos according to what I have read is really strong, and I believe that just because you want to get better and feel that something will make you feel better it will make you feel better and many of your illnesses are in your head and the fake idea that it is going to cure you makes your mind think that and therefore you get better, and placebos should be legalized since they would help really expensive medicine get cheaper and there will be less need of it since many of the diseases can be cured with a simple placebo but doctors give you very expensive medicines so they can get more money and they would have the same effect as a placebo, this is really sad and it probably wont be legalized since the bussiness is so big and it would not help the farmaceutical business and the corruption is so big and they have a huge influence on them.
