A study of Melbourne women found a decline in sexual interest, arousal, and frequency during menopause, with estradiol levels plummeting. Relationship factors, not hormonal changes, have the greatest impact on sexual response.
The study suggests that objects are recalled by uniting different brain regions, with the thalamus regulating electrical rhythms to connect these areas. This theory may help explain why some memories are clear while others are fuzzy.
A study by European psychologists found that people remember natural scenes significantly better when they're in color rather than black and white. The researchers also discovered that unnatural colors do not strengthen memory, suggesting that the brain is tuned to the color structure of the world.
A study suggests that hypnosis doesn't enhance the reliability of memory, but increases confidence in inaccurate memories. Researchers found that students under hypnosis were more reluctant to change their answers when told they might be wrong, indicating a higher level of confidence in their estimates.
