Titchner named Wundt ’s approach structuralism. William James gave field an "American Stamp‚" invented functionalism Contemporary approaches to psychology Biological Approach (focus on the body) Neuroscience Behavioral Approach (behavioral responses and their environmental determinants) Psychodynamic

Parasympathetic Dominants often use sleep to overcome energy losses following periods of sustained alertness. The Autonomic Nervous System • The sympathetic branch of the autonomic nervous system is responsible for functions that require focus and decision making. It’s the branch that speeds up when you need to go fast. It goes into high gear when an emergency situation requires quick thinking and reflexes‚ spurts of energy‚ hyper vigilance‚ and rapid heart rate - a need to “fight or flee fast”

If your mind interprets a stressful event as an emergency threat‚ it triggers an immediate response in the autonomic nervous system. Your stress response kicks in and activates the sympathetic nervous system (SNS). Your body is flooded with hormones that heighten the senses‚ increase heart rate and blood pressure‚ and focus the brain’s activity. The parasympathetic nervous system (PNS)‚ which is responsible for physical relaxation and emotional calm‚ becomes overwhelmed by this sympathetic response

simultaneously and very quickly. The brain itself requires extremely fast speeds to operate at even at the simplest level. How do the biological tissues of our body support such rapid coordination of the brain‚ limbs‚ and sensory input? They do so with nervous system tissue that imitates electrical wiring.

people) Normally‚ neurons in the central nervous system (the brain and spinal cord) cannot regenerate injured nerve fibers‚ limiting people’s ability to recover from brain or spinal cord injuries. Repair of the central nervous system and restoration of voluntary motor activity through axonal re-growth has long been considered impossible in mammals. Over the last decade‚ numerous attempts proved disappointing overall. While repair of the central nervous system has long been considered impossible have

As we human being are biological being‚ we need to understand our biological make up‚ and we can only fully understand the different parts of our bodies by studying further. This essay aims to address research methods used to study and understand how we evolved. Our knowledge of the human body has grown and psychology itself has become an expanding field of knowledge‚ various research and studies have been

They are many different areas in the field if neuroscience. Neuroscience deals with the five senses‚ anything connected to the nervous system‚ the brain‚ anything that sends information to and from the brain‚ etc. Many of these things go from simple ideas and concepts to the complex coding

Behaviour: Actions and responses that we can directly observe. Mind: Internal states and processes‚ such as thoughts and feelings‚ that cannot be seen directly and that must be inferred from observable‚ measurable responses.

HUMAN AS A COMPLEX ORGANISM The human body is a complex system of cells‚ most of which are grouped into organ systems that have specialized functions. These systems can best be understood in terms of the essential functions they serve: deriving energy from food‚ protection against injury‚ internal coordination‚ and reproduction. The continual need for energy engages the senses and skeletal muscles in obtaining food‚ the digestive system in breaking food down into usable compounds and in disposing
