Kvinderne - alle dem jeg kender og har kendt - opfatter Julen som et kreativt frirum hvor de - legitimt og med glæde - kan klippe, klistre, bage, sy, strikke, dekorere, farve, forme, modellere - you name it.
Erindring: For min mor der var hjemmegående husmor - (og ubevidst frustreret over det) -var hele Julemåneden en lang kreativ tour-de-force af rumudsmykning, bagning, konfektlavening, nisselandskabsbyggeri, produktion af nye former for julestads - hele registret.
Alt for damerne fik baghjul.
Og Juleaften gik det tit galt. Vi fire børn havde svært ved at leve op til hendes drømme om den perfekte og idylliske familiejul. Vi skændtes og brokkede os, var misundelige på hinanden, og gaveudpakningen var et rent kaos.
Klimaks var næsten altid noget af en nedtur for min mor.
Fagudtrykket på engelske er 'connectivity' - som altså kan være højere eller lavere i forholdet mellem forskellige af hjernens centre.
Psychological testing has consistently indicated a significant difference between the sexes in the ability to perform various mental tasks, with men outperforming women in some tests and women outperforming men in others. Now there seems to be a physical explanation, scientists said. “These maps show us a stark difference - and complementarity - in the architecture of the human brain that helps to provide a potential neural basis as to why men excel at certain tasks, and women at others,” said Ragini Verma, professor of radiology at the University of Pennsylvania in Philadelphia.
Ragini Verma said the greatest surprise was how much the findings supported old stereotypes, with men's brains apparently wired more for perception and co-ordinated actions, and women's for social skills and memory, making them better equipped for multitasking."If you look at functional studies, the left of the brain is more for logical thinking, the right of the brain is for more intuitive thinking. So if there's a task that involves doing both of those things, it would seem that women are hardwired to do those better," Verma said. "Women are better at intuitive thinking. Women are better at remembering things. When you talk, women are more emotionally involved – they will listen more."She added: "I was surprised that it matched a lot of the stereotypes that we think we have in our heads. If I wanted to go to a chef or a hairstylist, they are mainly men."
"It's quite striking how complementary the brains of women and men really are," Ruben Gur, a co-author on the study, said in a statement. "Detailed connectome maps of the brain will not only help us better understand the differences between how men and women think, but it will also give us more insight into the roots of neurological disorders, which are often sex-related."
1. Brain size: The male brain is typically about ten percent larger than the female brain. Although the extra mass does give males more processing power, this doesn’t make men more intelligent. Rather, science believes the reason for the increased brain mass is to accommodate the bigger body mass and muscle groups of the male (human).2. Brain hemispheres: Many men are sharply left-brain dominant, while women tend to be more evenly balanced between left and right-brain processing. Women are therefore thought to be slightly more intuitive, and sometimes better communicators. Men are often less socially adept, and are more task-oriented thinkers than females.3. Relationships: Women are purported to have better communication skills and emotional intelligence than men. Women tend to be group-oriented, and apt to seek solutions by talking through issues. Men can have trouble picking up on emotional cues unless they’re clearly verbalized – making for tricky communications between the sexes.4. Mathematical skills: The inferior-parietal lobule, which controls numerical brain function, is larger in males than in females. On standardized tests, men often score higher on mathematical tests than women.5. Stress: When faced with stressful situations, men usually employ ‘fight or flight’ tactics, while women use a ‘tend or befriend’ response that is rooted in their natural instincts for caring for their children and establishing strong group bonds.6. Language: Women often excel at language-based tasks for two reasons: two brain areas that deal with language are larger in females, and females process language in both hemispheres while males favor a single brain half.7. Emotions: Since women tend to have a larger deep limbic system then men, they’re more in touch with their feelings and are better at expressing their emotions. This makes women better at connecting with others, but unfortunately also more prone to different types of depression.8. Spatial abilities: The parietal region is thicker in the female brain, making it harder for them to mentally rotate objects – an important spatial skill. Women often report difficulty with spatial tasks, both on tests and in real life.9. Susceptibility to brain function disorders: Men are more likely to be dyslexic or have other language disabilities, since they’re more often left-brain dominant. Males are also more prone to autism, ADHD and Tourette’s Syndrome, while women are more susceptible to mood disorders like anxiety and depression. http://www.brainfitnessforlife.com/9-differences-between-the-male-and-female-brain/
- Mænd: De højt intelligent mænd der deltog i forsøget, havde særligt veludviklet grå substans bagerst i hjernens isselap. I dette område bearbejdes sanseindtryk.
- Kvinder: De højt intelligente kvinder i forsøget havde særligt veludviklet grå og hvid substans i pandelappen forrest i hjernen. Herfra kontrolleres vores sproglige evner.
Women have a higher proportion of gray matter to cranial volume than men. Conversely, men have higher proportions of white matter and cerebrospinal fluid to cranial volume than women. (...)
Gray matter is where computation takes place, while white matter is responsible for communication between groups of cells in different areas of the brain.
"With these findings, we are beginning to get an explanation for the lack of intelligence disparity between men and women," says Ruben C. Gur, Ph.D., professor of psychology in psychiatry and lead author on the new study, which will appear in the May 15 issue of the Journal of Neuroscience. "Women have a higher percentage of tissue devoted to computation than men. Men have a greater proportion of tissue assigned to the transfer of information between distant regions.
The study shows women having more white matter and men more gray matter related to intellectual skill, revealing that no single neuroanatomical structure determines general intelligence and that different types of brain designs are capable of producing equivalent intellectual performance.“These findings suggest that human evolution has created two different types of brains designed for equally intelligent behavior,” said Richard Haier, professor of psychology in the Department of Pediatrics and longtime human intelligence researcher, who led the study with colleagues at UCI and the University of New Mexico. (...)In general, men have approximately 6.5 times the amount of gray matter related to general intelligence than women, and women have nearly 10 times the amount of white matter related to intelligence than men. Gray matter represents information processing centers in the brain, and white matter represents the networking of – or connections between – these processing centers.This, according to Rex Jung, a UNM neuropsychologist and co-author of the study, may help to explain why men tend to excel in tasks requiring more local processing (like mathematics), while women tend to excel at integrating and assimilating information from distributed gray-matter regions in the brain, such as required for language facility. These two very different neurological pathways and activity centers, however, result in equivalent overall performance on broad measures of cognitive ability, such as those found on intelligence tests.
Når det gælder spørgsmålet om kreativitet i forhold til de to køn, så har vi et tilsvarende problem:
While men and women were indistinguishable in terms of behavioral performance across all tasks, the pattern of brain activity while engage in the tasks in question was indicative of strategy differences between the genders. Brain area related to semantic cognition, rule learning and decision making were preferentially engaged in men during conceptual expansion, whereas women brain activity while engaged in regions related to speech, processing and social perception. During divergent thinking, declarative memory related regions were strongly activated in men, while regions involved in theory of mind and self-referential processing were more engaged in woman.
