" Psychology is the science of human nature. It's all about studying the human mind so that we can figure out why people think, feel and act as they do. How do we fall in love, communicate with each other, solve problems, and learn new things?"
Describe human behavior is difficult we see things through the filters of our prior experiences, our cultural values, and our believes. Psychologists often focus on the motives driving a person's behavior; the best predictor of the future behavior is past behavior.
Science gave psychologists some clear guidelines for studying human behavior; be skeptical; keep your values and opinions separate from your ideas and believes; ask only questions that can be answered with evidence; show other people your results, and make sure they can check your answer.
Psychologists developed many different approaches to the study of human nature some study the Mind and the others study the human behavior.
We have perspectives today that offers insight into human nature, the biological perspective looks to the body (hormones,genes, the brain and the central nervous system to explain the mind; the psycho-dynamic perspective mental conflicts deep within the subconscious - psychoanalysis; behavioral perspective seek to understand people by studying what happens to them and how they respond; cognitive psychology study of people's ability to acquire, organize, remember, and use knowledge to guide their behavior; Evolutionary psychology applies the principle of natural selection to human behavior; Socio -cultural perspective focus on the difference among people living various culture as well as the way a people's culture influences their thoughts, feelings and behavior; Evolutionary perspective the very fact that we exist that means that our ancestors possessed favorable characteristics that enable them to adapt and flourish in their natural environment.
To understand human nature we must first understand how the brain functions because there is a biological counterpart to every thought or feeling we have. physical changes in the brain can produce dramatic changes in human behavior.
The brain contain more cells than there are stars in the universe. And each one works together to produce, direct, and choreograph what we think, feel and do.
Brain stem regulates the internal physiological state of the body;
Medulla Regulates breathing during sleep;
Pons regulates brain activities during sleep;
Reticular formation arouses the brain to attend to new stimuli even during sleep;
Thalamus The relay station between senses and the cerebral cortex;
Limbic system regulates motives, drives, feelings, and some aspects of memory
Hippocampus the key play in long term memory;
Amygdala memory, emotion and basic motives;
Hypothalamus eating, drinking, sexual arousal, body temperature;
Cerebrum higher levels of thinking and feelings;
Cerebral hemisphere each half controls different cognition and emotions
Corpus Callossum connects the two hemispheres allowing them to communicate with each other.
Is defined as the manifestations of mental disorders; study of mental disorder (problems, causes, and process) involves impairment, deviance and distress. Mental disorder must produce clinically significant impairment or distress in one's social, or occupational life.
Define clinical entities - same understanding of the diagnose. Determine the treatment, have identified major depression the clinical provide antidepressants.
Psychopathology manifests as symptoms and signs. Symptoms are experienced subjectively, cannot be observed, and must be reported by the patient. Signs can be observed and documented objectively.
Formal process that collects clinical information from many source in order to reach a diagnosis make a prognosis to render a biopsychsocial formulation and to determine the treatment .
The patient interview is usually the principal of data; it's not the only one.
Philosophy and Psychology of human nature and Psychopathology according to ancient system of knowledge:
The Ego identifies himself with the body so Man undergoes various suffering and strives for liberation. The Ego is one of function of the Mind through ignorance believes he is the body.
With controlled Mind and an intellect you must realize your own nature; who you really are. The mistake about a human nature happens through ignorance because Man thinks he is his body, mind or sense organs including brain.
Therefore he nourishes the body and anoints it and guards it careful.
In the books explaining the nature of the Mind is formed by the concretion of the subtle portion of the food we eat; it grows with passions such attachment and aversion, desire and anger; being the aggregate of mind intellect, memory and egoism.
The characteristics that it bears are thinking, determining; since it is an object of consciousness it is what is seen, inert, even though inert appears as if conscious because of association with consciousness being.
It is the adjunct of the individual soul; thinking of an object it transforms itself into a mode, and along with the knowledge that is in the brain, it flows through the five senses channels, gets joined to objects by the brain (that is associated with knowledge) and thus knows and experience objects and gains satisfaction.
The Mind itself is of the form of all Soul, God and World.
