The aim of this research was to determine the relationship between dopamine rich areas of the brain and feelings of love. Participants were placed in an fMRI machine and first shown a picture of a loved one, then instructed to perform a task, then shown a picture of an acquaintance, and then perform another task. The study found that different regions of the brain were activated when looking at a loved one versus an acquaintance. Their findings supported the hypothesis that love was linked to dopamine rich regions of the brain.

The aim of this investigation was to examine the validity of conformity in a group setting. Participants in the experimental group were asked to match pairs of lines of similar length in the presence of confederates who either provided correct or false answers. The control group did the line task alone. Results showed that those participants in the experimental group were more likely to change their answer to the incorrect one if the confederates also said the wrong answer. This displayed conformity: a change in an individual's behavior or cognition to be in line with the group's consensus.

The aim of this study was to investigate the role of cultural schema on memory and reconstruction. British participants were instructed to read a Native American story two times, then recall the story to the best of their ability. Results showed that the participants had a tendency to swap or fill in parts of the story with objects or elements that were more in line with their own cultural norms (ex: swapped the word canoe for boat). This showed that cultural schema influence how we perceive and recall memories.

This research investigated the effects of the environment on brain growth and development. The methodology was an experiment. Rats were randomly chosen and assigned to an enriched environment or deprived environment. Rats in the enriched environment had larger brains and more acetylcholine in post-mortem analysis. This proved the relationship between the environment and brain development and growth. Who conducted this research?

The aim of this study was to look at how in group biases are manifested in individual's behaviors and cognition. Researchers took boys to a secluded location and separated them into two groups. The groups participated in competitions over the course of a couple of days. Researchers observed clear prejudices against the out group and strong preference for their own group developing in the boys after the competitions. This study has been criticized for gender bias and ecological validity.

The aim of this study was to investigate how external sources of information can interfere with memory reconstruction. Participants watched a video of a car crash at a controlled speed then filled out a questionnaire. The experimental questionnaire used a suggestive word when asking what the speed of the car was and the control used a bland word. Results showed that the experimental group tended to report higher speeds than the control group, suggesting that the presentation of an influential outside source of information caused a change in memory of the video. A limitation of this study was the natural human error in guessing speed, which could have accounted for the significant difference.

The aim of this experiment was to determine where the engram was, if it was real. Researchers had mice learn a maze, then created lesions in the brain, and tested the mice's ability to run the maze again. The mice were able to perform the maze with lesions. This study did not show the presence of an engram but researchers determined that memory is diffused throughout many areas of the brain and led to Equipotentiality theory. Who conducted this research?

The aim of this experiment was to study how social learning plays a role in our behaviors (social cognitive theory). Babies were either placed in a room with an adult who aggressively treated a toy doll or one who nicely treated a toy doll. When the babies were left alone with the doll, they tended to treat the doll in a similar way that the adult who they observed did. This suggested that a component of how we learn can be attributed to social modeling and observation.

The aim of this study was to investigate the role of schema in reconstruction of memory. Participants were taken to a university office, allowed to stay for 35 seconds, then removed from the office. Once removed, the participants were asked which objects they remember seeing. Participants tended to report typical office items but often failed to notice the atypical ones such as a wine bottle and picnic basket. The failure to identify the atypical objects supported the idea that our memory reconstruction is based on preexisting cognitive frameworks.

The aim of this research was to look at the relationship between learning a new task and brain development. The research method was an experiment. Participants in the experimental condition were instructed to practice juggling for 3 months, then stop for 3 months. fMRI's were taken after each 3 month segment to measure brain development. The differences in brain change between the experimental and control conditions were found to be significant. Who conducted this research?

The aim of this study was to look at how racial prejudices and segregation affect the cognition of children. Researchers presented children with four dolls equal in all features other than the color of their skin. The children were asked what color the dolls were and which one they preferred. All children, regardless of race, tended to prefer the white doll over the black one. This demonstrated that social prejudices affect the cognition of individuals who are subjected to them.

The aim of this study was to investigate the relationship between rehearsal and short term memory, and more specifically how memory is impaired when rehearsal is limited. Participants were presented a series of 3 letter sequences (trigrams), then instructed to wait for different periods of time before recalling those letters. During the time, participants had to count backwards out loud in order to prevent active rehearsal. The results showed that the longer the break between presentation and recall, the less trigrams were remembered. This showed the time limitations of short term memories and the role of rehearsal in developing memories.

The aim of this study was to look at how MHC genes impact mating preferences in humans. Male participants were instructed to wear t-shirts for 2 nights in a row and make sure to not contaminate the shirts with other smells. Then, female participants ranked the t-shirts from 1 to 6. MHC gene-different shirts proved to be preferable in the experiment demonstrating a link between MHC genes and their associated fragrances and female partner preference. Who conducted this research?

The aim of this study was to investigate the effects of discrimination and group biases on the self esteem of children. Researchers segregated a classroom by eye color: blue or brown, and told the children of one group that they were better than the other. Shortly after, the superior group believed that they were better and the other group had the tendency to perform worse academically and be more timid. The results proved that prejudices have an effect on cognition and academic performance. This study has been ethically criticized for the emotional impact which the children may have suffered and lack of proper briefing.

The aim of this study was to examine how having previous knowledge of a topic affects our further learning of that subject area. The experimental group were briefed on a lesson, read the lesson, then completed a comprehension task. The control group read the lesson, were then briefed on the lesson, then completed the comprehension task. The experimental group had better scores on the comprehension task. This suggests that having previous cognitive frameworks enhances learning and the study supports schema theory.
