Human Psychology Questions and Answers (Q&A)

The brain is known to be a complex organ in the vertebrate body and it is active during dreams. Thus, brain generates two distinct types of sleep which were slow wave sleep (deep sleep) and rapid eye movement (REM). Dream is experienced in all stages of sleep but it is vivid during the rapid eye movement (REM) which is controlled by reticular activating system which runs from the brain stem through the thalamus to the cortex.

However, cortex is known to be responsible for the contents of the dream and limbic system which is found in the mid-brain deals with emotion that is involved in dreaming and waking while amygdala is associated with fear and it is active during dream.

The term dementia is nonspecific. It is a term used to describe a group of symptoms associated with a decline in memory or other thinking skills. Dementia can be reversed if it is caught early enough. You have to attend to all the factors that affect brain function. This includes diet, exercise, stress, nutritional deficiencies, toxins, hormonal imbalances, and inflammation.

In the case of most progressive dementias, including Alzheimer's Disease, there is no cure and no treatment that slows down the progression of it. There are drug treatments that can temporarily alleviate symptoms. Dementia is irreversible when it is caused by degenerative diseases or trauma, but might be reversible in some cases when caused by drugs or alcohol. It may also be caused by hormone or vitamin imbalances or depression.

The short answer to this is that if a man feels horny and he has no partner, he might well get desperate for sex. But you say 'men' as if the explanation for one man's behaviour is an explanation for every single man's interest and longing for sex. The sex drive is very much higher in males under forty than after this, but again, this is a generalisation that doesn't always hold.

Believe it or not, there are some men whose sex drive is quite low and who may be content to go months without sexual gratification. If, however, you have been turning a man on and not allowing sexual activity, he might well be acting 'desperate'

The two main factors affecting intelligence are the genes you are born with, and the opportunity for developing this potential. Without sufficient nutrition the brain, like other organs, will suffer. Similarly, without access to mental stimulation and challenge - basically the opportunity to learn - the potential for intelligent behaviour is limited to a degree. For instance, the recent case of the Californian youngsters starved, tied up and psychologically abused will have suffered detriment to their intelligence as well as to their health.

Added to this, the parents' failure to educate them has severely limited their opportunity to learn. It will be interesting, in future years, to compare the outcome of the oldest two children, the second of whom is the only one who ever went to school, whereas the oldest is the one who suffered the longest period of deprivation, physical and mental. Such cases are rare: most people in the western world have books, sufficient food and access to various modes of learning (Films, videos, internet) for their potential intelligence to be realised.

Cushing syndrome is also known as hypercortisolism, it is a disorder that was caused by prolonged use of glucocorticoid hormone (medication) used for rheumatoid, asthma, lupus, arthritis and can also be used for immunosuppression after transplantation. Thus, glucocorticoid hormone is a powerful anti-inflammatory medication that if taking too much can result to cushing’s syndrome.

Also, this disorder can be caused by a tumor in the pituitary gland that is found at the base of the brain and it is commonly found in women than men between the ages of 25 to 40 while children with this condition experience slow growth rate and generally obese. However, the common signs and symptoms of cushing’s syndrome includes abdominal obesity with thin legs and arms, high blood pressure, irritability, severe fatigue, anxiety, headache and depression.

Scientists conducting research at the University of St Andrews in the United Kingdom now think they may know what is responsible for déjà vu, the feeling you experience when confronted with something new but you feel you’ve been there before. Using fMRI (functional Magnetic Resonance Imaging), the researchers scanned the brains of 21 volunteers while the volunteers were experiencing déjà vu. They expected to see activity in areas of the brain involved in memories, such as the hippocampus.

But, instead they found that the “frontal areas of the brain that are involved in decision making were active instead”. These scientists then came to the conclusion that when a person experiences déjà vu, their brain is “probably checking through our memories, and sending signals if there’s some kind of memory error – a conflict between what we’ve actually experienced and what we think we’ve experienced.”

Nihilism is known to be the rejection of anything that is moral and religious. Those who consider themselves to be nihilists feel that life has no meaning. They do not understand the need to make use of their emotions. Existential nihilism is also the belief of some people that all of the human beings that are in this world will not have anything good to contribute to the world.

They believe that human beings are not capable of doing anything that might change the world. This belief can be hard because this means letting go of all the meaningful aspects of life to the point that they also abhor the mere existence of people.

I think it is more a failure of people to realize that there is no such thing as "exact intelligence" The IQ - intelligence quotient - is a measure derived from a number of different intellectual areas: memory, vocabulary, verbal reasoning, spatial skill, non-verbal reasoning. If a reliable and valid test is used, such as the Wechsler Scales, the resulting IQ should be a good measure of present intellectual functioning.

If you seek something akin to the number of seconds a runner takes to cover a set distance, you will be disappointed. There is no discrete point at which someone's intellectual ability falls. A seasoned psychologist will normally give IQ test results as a range within which the individual's score will fall 90% of the time.

Carl Gustav Jung was a Swiss psychologist and psychiatrist who was a follower of Freudian theory but then departed from it to some extent because he disagreed with Freud's emphasis on sexual causation in some personality dysfunctions. Jung founded Analytic Psychology, in response to Freud's Psychoanalysis. It was Jung who named and developed the concepts of Extraversion and Introversion, so much part of our thinking today.

His theory of archetypes has also been prominent in the field of literature, even religion, as well as psychiatry. Jung also proposed the concept of a Collective Unconscious, thus developing Freud's work on the Unconscious in driving behaviour. His knowledge of history and understanding of personality led to a gentler, more restorative psychiatric approach. His life span was 1875-1961 but his influence remains as strong as when he lived.

Lucid dreaming differs from normal dreaming in that with lucid dreaming a person is actually aware that they are dreaming while they are dreaming. In most sleep studies, scientists use electroencephalography (EEG) to record brain activity during sleep. They have determined that “lucid dreams are infrequent – less than 1 percent of dreams in most studies”. Normal dreaming happens quite frequently, most often during REM (rapid eye movement) sleep.

But normal dreaming can also occur during non-REM sleep periods. One theory of dreaming is that the cortex of a person’s brain is almost as active during REM sleep as it when a person is awake and it is this “rhythmic burst” of activity that causes dreaming. Another theory is that lower brain stem activity stimulates or activates the cortex which then causes dreaming.
