THE BRAIN AND PSYCHOLOGY

Consciousness and the brain

Scientists have been studying the conscious mind since the first half of the 20th century.

Consciousness could be defined the awareness of one’s self and the environment surrounding.

Cognitive Neuroscience is the study of the brain activities that focuses on cognitive processes. To understand the neural basis of cognition and emotion, cognitive neuroscientists observe language, memory, perception, cognitive thinking, etc. By observations, they could prevent and give proper treatments to mental illness patients.

Human body uses all senses to receive, transform and deliver neural messages.

 

The behaving brain is a collection of neurons made up of 10 trillion cells.

Three main function of the behaving brain is learning, remembering, and deciding.

These functions take part in imaging and recording electrical activities.

 

The brain itself is a drug factory. It releases hormones into the blood stream when the body needs to control pain, when excitement occurs or when creating and storing memories.

 

The Responsive brain is acting by the influence of response to create behaviors appropriate to the environment.

The Behaving Brain vs. The Responsive Brain

The Responsive brain is acting by the influence of response to create behaviors appropriate to the environment.

 

Vision, Hearing, Taste, Smell and Touch are the five different senses.

 

Using the sensory receptors cells, sensations receive and transport the information to communicate with the brain.

 

Visual receptors contains chemical to transform light waves in to images and colors.

 

The ears are structured to receive sound waves for hearing stimulation.

 

The four basic tastes include salty, sweet, sour and bitter.

 

Smell is a lot more sensitive than taste that can trigger and recreate memories by odors.

 

Touch is an important sense that helps develop security and health in early development stages.

 

Premature infants responds better with human touch; they would gain weight easier than those without care.

 

Reduced of bio chemical substance required for growth could affect a person height and body dysfunction.

 

 

Sensation and Perception works together to secure survivals.

 

Perception is a mental process to organize and interpret sensory input to respond to information.

 

Images and figures can be interpreted in many different ways.

 

The brain uses the laws of grouping to group familiar objects or similar figures together in groups.

 

Proximity – objects that are near to each other

Similarity – similar in appearance

Continuity – series of points and lines that are match together

Common fate – elements that are moving together

Law of good continuation – lines or patterns that flow in particular directions to create shapes

Closure – looking at the whole picture with missing parts of the figure

Simplicity – simplify to organize the image

Law of subjective contour – the missing figure that does not appear

Inclusiveness – figures within a bigger image

 

Illusions are created from distorted physical conditions, to be perceived as they exist.

 

Depth perception can be perceived by monocular cues (from one eye) or binocular cues (using both eyes)

 

A new field of psychology study focused on paranormal phenomena is called Parapsychology.
