我女友是否心理有問題,還是正常的? (20分)

佢的心理正常
1. 佢的需要比你多
li個係每人的性慾不同罷了
2. 佢要求你買水手服, 肚兜之類的服飾
可能想性行為時增加性趣
or佢鍾意li d 服飾
or佢想吸引你
(你性需要比佢少,可能佢以為佢自己唔夠吸引)
3. 佢的衣著開放
係與個人性格有關
與心理無關
除非她不停刻意曝露
就可能有問題

唔使咁擔心,好奇心人人都有,唔使諗咁多

Study of the brain

[edit] Fields of study
Neuroscience seeks to understand the nervous system, including the brain, from a biological and computational perspective. Psychology seeks to understand behavior and the brain. Neurology refers to the medical applications of neuroscience. The brain is also one of the most important organs studied in psychiatry, the branch of medicine which exists to study, prevent, and treat mental disorders.[7][8][9] Cognitive science seeks to unify neuroscience and psychology with other fields that concern themselves with the brain, such as computer science (artificial intelligence and similar fields) and philosophy.


[edit] Methods of observation
Main article: neuroimaging
Each method for observing activity in the brain has its advantages and drawbacks.


[edit] Electrophysiology
Electrophysiology allows scientists to record the electrical activity of individual neurons or groups of neurons.


[edit] EEG
By placing electrodes on the scalp one can record the summed electrical activity of the cortex in a technique known as electroencephalography (EEG). EEG measures the mass changes in electrical current from the cerebral cortex, but can only detect changes over large areas of the brain with very little sub-cortical activity.


[edit] MEG
Apart from measuring the electric field around the skull it is possible to measure the magnetic field directly in a technique known as magnetoencephalography (MEG). This technique has the same temporal resolution as EEG but much better spatial resolution, although admittedly not as good as fMRI. The main advantage over fMRI is a direct relationship between neural activation and measurement.

每人性取向不同，各人有各人情趣需要，只要不越軌，一切正常。
