Psychology – study of behavior and the mind Dualism – the mind is spiritual and the body is physical and they are connected the mind can’t be studied Introspection – Wundt Observers report their reactions TO light, colors, and time perception Psychoanalysis – Freud’s theory of personality and method of psychotherapy, both of which assume the importance of the unconscious process. Behaviorism – scientific study of observable behavior Cognition – the mental process thinking, knowing, and remembering. Basic research – research that tests theories. Applied research – research to solve practical human problems Theory – describes predicts and explains a phenomenon. Hypothesis – testable prediction, usually derived from theory Laboratory research – in regulated environment and everything can be observed Field research – in the real world Self-report – asking people about their own thoughts and feelings Behavioral observation – a form of research based on firsthand observation of a subject’s behavior. Archival research – research that relies on preexisting records Statistics – math used to analyze research data Case studies – research that involves in depth personal observations Surveys – research method that interviews or questions large groups of people Epidemiology – study of distribution of an illness in a population Random sample – a method of selection in which everyone has an equal chance of being chosen Naturalistic observation – observation of behavior as it occurs naturally in real-world settings.
The Research paper on Theory Of Mind Evolutionary Psychology Situation
Describe what evolutionary psychologists mean when they employ the term 'theory of mind'. Use examples and research studies from Book 1, Chapter 2 to show why this theory is important in evolutionary psychology. Evolutionary psychology is a specialist field within the spectrum of psychological enquiry, which seeks to examine and understand some of the predominant reasoning behind the concept of ...
Correlation – a statistical measure of the extent to which two variables are associatedScatterplot – a graph which has dots for X and Y and reveals direction and strength of their correlation. Experiment – research in which an investigator changes and keeps constant the variables on randomly assigned subjects. Independent variable – any variable that the researcher manipulates in an experiment Dependant variable – a variable that is being measured in an experiment Experimental group – the group that is exposed to the independent variable Control group – the group that isn’t exposed to the independent variable Random assignment – random assignments to an experiment Replication – the process of repeating an experiment to see if the results are reliable enough to be duplicated. Generalizability – the extent to which a finding relates to, such as a certain population. Meta-analysis – statistical procedures used to review a body of evidence by combining the results of individual studies.
Deception – misleading subjects to the true purpose of a study. Informed consent – ethical requirement if one wants to participate in a study (of ones own free will) Evolutionary psychology – principles of evolution to understand human social behavior Behavioral genetics – genes and their affect on behavior Behavioral neuroscience – links among the brain, nervous system, and behavior. Cross-cultural research – compares and contrasts people of different cultures. Multicultural research – studies designed to compare and contrast racial and ethnic minority groups within cultures. Chap 2 Central nervous system CNS- nerves in the brain and spinal cord Peripheral nervous system PNS- nerves from the CNS to the body, consists of somatic and autonomic nerves Somatic nervous system – transmits sight, sounds, tastes, smells, and pain, (from sensory organs to the CNS) and controls the body’s voluntary movements. Autonomic – connects the CNS to the smooth involuntary muscles heart, lungs, stomach, liver.
The Essay on Body Cells Carbohydrates Energy
Carbohydrates supply us with the energy needed in our daily activity. Carbohydrates are essay to convert to glucose, the fuel for body cell. Lacking glucose will direct affect to our moon and behavior. Simple sugar and complex carbohydrates are the two major forms of carbohydrates. Proteins are repairing bone, muscle, skin, and blood cells. Proteins are also protecting us from disease, such as ...
Sympathetic NS – division of the autonomic NS that heightens arousal and energizes the body for action. Parasympathetic NS – division of the autonomic NS that reduces arousal and restores the body to its pre-energized state. Endocrine system – ductless glands that regulate growth, reproduction, metabolism, and behavior by secreting hormones. Hormones – chemical messengers from endocrine glands into the bloodstream and go to various organs in the body. Pituitary gland a tiny gland in the brain that regulates growth and stimulates hormones in other endocrine glands at the command of the hypothalamus Neurons – nerve cells that are the building blocks of the NS Sensory neurons – neurons that send messages from the senses, skin, muscles and internal organs to the CNS Motor neurons – neurons that transmit commands from the CNS to muscles, glands, and organs. Interneurons CNS neurons that connect sensory inputs and motor outputs.
When a thyroid gland produces too little hormone, people become easily tired and sensitive to cold. When the thyroid produces too much of the hormone, people tend to get nervous and irritable and lose weight. Neurons send signals throughout the body as electrochemical signals. People estimate between 100 to 200 billion neurons in the brain glia l cells are smaller than neuron cells but they outnumber the neurons 10 to 1 so most the brain is made up of glia l cells. Neural signal travel from dendrites through the (cell body) soma, down the axon, and into the axon terminals. Action potential – electrical impulse that surges along the axon, caused by an influx of positive ions in the neuron.
Threshold – level of stimulation needed to trigger a neural impulse. Soma- cell body of a neuron Dendrites – extensions from the cell body that receive incoming impulses Myelin sheath tiny white layer of fat cells around the axon to insulate it. CT – computerized tomography computer enhanced X-rays sent to the brain at 1 degree intervals of a 180 degree arc the computer turns it into an image its used in finding tumors and strokes Positron emission tomography – PET glucose supplies the brain with energy and we can see how much glucose is used in a region. a tiny amount of radioactive glucose is injected into the brain the scanner reads the amounts consumed in different regions.
The Effects of Heroin on a Person’s Brain and Body: a Literature Review
The Effects of Heroin on a Person’s Brain and Body: A Literature Review Heroin, also known as diacetylmorphine, is an illegal drug in the United States and many other countries. Heroin has devastating results on the brain and body. This paper looks at heroin’s history, its consequences on the brain and body, addiction possibilities, and available options for treatment for heroin abusers. What is ...
Red, yellow, orange means high activity Violet, blue, and green mean low activity. MRI magnetic resonance imaging- a magnetic field aligns the brains atoms then a pulse of radio waves disorients the atoms, which give off detectable signals as they return to normal FMRI – a faster version of an MRI Brainstem medulla (swallowing, breathing, heart rate) damage = death, pons (sleep, arousal) damage = coma, reticular formation (sleep arousal and attention) Basal ganglia and cerebellum – play an important with balance Surrounding the brain stem Limbic system. Motivation and emotional responses. Above the brain stem is the Limbic system Thalamus sensory relay station directs neural traffic between the senses and cerebral cortex.
Amygdala – aggression center controls fear, anger and aggression Hippocampus – plays a key role in new memories. Largest structure in the limbic system Hypothalamus – helps regulate the autonomic nervous system glands, emotions, and basic drives and regulates the body temperature, and activities of the autonomic nervous system, controls the endocrine system by triggering the release of hormones into the bloodstream, helps regulate emotions, fear and rage, and is involved with drives as hunger, thirst sleep, and sex. Pituitary – in the amygdala in the limbic system controls hormones and growth Cerebral cortex – 80% of the brain the outside higher-order mental processes it consists of two hemispheres and 4 lobes it can also be divided into areas based on function (1) sensory areas specialize in receiving sensory information. The cortex receives info from touch receptors in the skin. (2) motor cortex controls the voluntary muscles (3) the association cortex communicates with sensory and motor areas and house higher mental processes two areas within associate with language. (4) Broca’s area directs speech and Wernicke’s area is involved in language comprehension.

... of the hierarchical organisation of the cortex. There is evidence that the sensory structures within the brain are organised in a hierarchy, ... for a function in isolation and that either hemisphere can control functions which were originally located in the other hemisphere ( ... which area is responsible for the function deficit. A more scientific approach would be to assess the function of the system ...
Fechner said that each side of the brain has its own mind- the left controls the right the right controls the left they share info and connect at through the corpus. Split brain the corpus is severed – patients show that each side of the brain has a somewhat different version of experience. Research has tried to find which side is lateral ized (which side controls what) LEFT controls language the RIGHT is nonverbal the LEFT is analytical and the RIGHT is more holisticAcetycholine, dopamine – neurotransmitter Endorphin – body produced morphine Phrenology bumps on the skull reveal psychological characteristics. Somatosensory cortex – receives sensory info from touch receptors in the skin. Motor cortex – sends impulses to voluntary muscles Association cortex – areas of the brain that communicate with the sensory and motor areas and house the brain’s higher mental processes. Plasticity – capacity to change as a result of experience.
Concussion – alteration in a persons mental state due to trauma to the head. Neural graft – transferring healthy tissue from one animal to another.
