What was the aim of Antonova et al. (2011)?
To investigate whether scopolamine affected hippocampal activity in the creation of spatial memory
The study involved 20 male adults playing a VR game while being injected with either scopolamine or a placebo.
What were the results of Antonova et al. (2011)?
Scopolamine: Significant reduction in the hippocampus compared to when they received the placebo
Acetylcholine plays a key role in the encoding of spatial memory.
What was the aim of Maguire et al. (2000)?
To investigate whether neuroplasticity occurs in London cab drivers
Cab drivers must memorize 25,000 street names, landmarks, and more.
What did the MRI results reveal in Maguire et al. (2000)?
The posterior hippocampus was significantly larger in taxi drivers, while the anterior hippocampus was larger in the control group
There was a positive correlation between years of experience and the size of the posterior hippocampus.
Who was HM and what was significant about his case?
HM was a patient who underwent surgery that resulted in anterograde amnesia, losing the ability to form new memories
His case helped to understand the role of the hippocampus in memory.
What methodology did Milner use to study HM?
Method triangulation including IQ testing, direct observations, interviews, and cognitive testing
This approach provided a comprehensive understanding of HM’s cognitive abilities.
What were the findings regarding cortisol in Newcomer et al. (1999)?
High cortisol levels negatively affected verbal declarative memory
Participants receiving high cortisol showed worse performance in memory tasks.
What was the aim of Zhou et al. (2014)?
To investigate the influence of potential human pheromones on sexual behavior
Two potential pheromones studied were androstenedione (AND) and estratetraenol (EST).
What were the results of Zhou et al. (2014) regarding gender perception?
AND-biased heterosexual females and homosexual men perceived stick figures as more masculine, while EST-biased heterosexual males and homosexual females perceived them as more feminine
This indicates the potential influence of pheromones on gender perception.
What was the aim of Caspi et al. (2003)?
To determine the role of 5-HTT alleles in depressive disorder
The study involved 847 participants from New Zealand.
What were the results of Caspi et al. (2003) regarding the 5-HTT allele?
Participants with the mutated 5-HTT allele were more likely to experience depressive symptoms
Stressful life events must trigger the individual for depression to manifest.
What was the aim of Bouchard’s Twin Studies?
To investigate the heritability of intelligence in MZA and MZT twins
The study included 137 pairs of twins tested over 20 years.
What were the IQ concordance rates found in Bouchard’s Twin Studies?
69% for MZA twins and 88% for MZT twins
This indicates a strong genetic component to intelligence.
What was the aim of Wedekind (1995)?
To determine whether MHC affects mate choice
The study involved male participants wearing T-shirts to assess odor preferences.
What were the findings regarding women’s preferences in Wedekind (1995)?
Women scored male body odors as more pleasant when they differed from their own MHC
This suggests a biological basis for mate selection based on genetic compatibility.
