Final Exam Review Flashcards
What is the Scientific Method?
A systematic procedure of observing and measuring phenomena (observable things) to answer questions about what happens, when it happens, what causes it, and why. This process involves a dynamic interaction between theories, hypotheses, and research method
What is the purpose of psychology?
The study of mind & behavior which depend on processing in the brain.
- Mind: mental activity (outside ourselves)
- Behavior: actions that result from sensing and interpreting info (inside ourselves)
What is Critical Thinking?
Systematically evaluating information to reach conclusions based on the evidence presented
Three steps in thinking critically
1. “What is the claim I am being asked to accept?”
2. “What evidence, if any, is provided to support the claim?”
3. “Given the evidence, to what extent should the claim be accepted or rejected?”
What is Nature?
refers to biological/genetic predispositions’ impact on human traits
What is Nurture?
describes the influence of learning and other influences from one’s environment.
What is Cognitive Psychology?
the study of how people think, learn, and remember. George Miller & Ulric Neisser.
What is Humanistic Psychology?
investigates how people grow to become happier and more fulfilled & focuses on people’s basic goodness. Developed by Rogers
What is Behaviorism Psychology?
emphasizes the role of environmental forces in producing behavior. John. B. Watson. (BF. Skinner).
What is the Gestalt Theory of Psychology?
the idea that the world of personal experience is different from simply the sum of its parts. Max Werteimer & Wolfgand Kohler. Developed in opposition to structuralism.
What is Psychoanalytical Psychology?
our thoughts and actions are influenced by unconscious mental factors. Sigmund Freud. Used to help others become more accepting of unconscious.
What is Functionalism Psychology?
psychology concerned with the adaptive purpose, or function, of mind & behavior. James. Describes how the conscious mind aids adaptations to an environment.
What is Structuralism Psychology?
psychology of the mind through introspection. Edward Titchener. The idea that conscious experience can be broken down into underlying parts.
What is Experimental Psychology?
the purpose was to identify the basic parts, or structures of the conscious mind. Wilhelm Wundt.
What is the nervous system?
A network of billions of cells in the brain and the body, responsible for all aspects of what we feel, think and do.
Has 3 basic functions:
1. Receive sensory input from the world through vision, hearing, touch, taste, and smell.
2. Process the info in the brain by paying attention to it, perceiving it and remembering it.
3. Respond to the info by acting on it.
How to do measure brain activity?
Electroencephalography (EEG) is used to show brain activity in certain psychological states, such as alertness or drowsiness. To prepare for an EEG, electrodes are placed on the face and scalp. After placing each electrode in the right position, the electrical potential of each electrode can be measured
What are the parts of the brain?
Occipital: vision (Front)
Parietal: touch, spatial relations (top back)
Temporal: hearing, memory (bottom)
Frontal: complex thoughts, planning, movement (very back)
What is Altered Consciousness?
The combination of a person’s subjective experience of the external world and the person’s internal mental activity; this combination results from brain activity.
Consciousness varies in terms of one’s level of awareness, and one’s state of awareness. 1. Normal waking state of consciousness; 2. Altered state of consciousness
What is a traumatic brain injury?
As in the case of “Iron Mike” Webster, concussions affect consciousness because they cause brain damage.
Severe concussions can cause traumatic brain injury (TBI).
Define Corpus Callosum.
This area contains the largest bundle of nerve fibers in the brain and connects the two sides (hemispheres) of the brain. The corpus callosum doesn’t just sit there, it is responsible for allowing the two hemispheres to communicate with each other and share information.
What is REM sleep?
Opposite of narcolepsy.
Those with the disorder act out their dreams while sleeping.
(Sleepwalking)
What is sleep apnea?
a person stops breathing because the throat closes; the condition results in frequent awakenings during the night.
What is Narcolepsy?
a person experiences excessive sleepiness during normal waking hours, sometimes going limp and collapsing.
What is Insomnia?
a disorder characterized by a repeated inability to sleep. Between 12-20% of adults are estimated to have insomnia. More common in women. Cognitive-behavior therapy effective. Changing your habits can be helpful.
What is the Germinal Period?
prenatal development from conception to 2 weeks after conception, when the zygote divides rapidly and implants in the uterine wall.
What is the Embryonic Period?
prenatal development from 3-8 weeks after conception, when the brain, spine, major organs, and bodily structures begin to form in the embryo.
What is the Fetal Period?
prenatal development from 9 weeks after conception until birth, when the brain continues developing, bodily structures refined, and the fetus grows in length and weight and accumulates fat in preparation for birth.
Describe a secure child attachment style.
distressed when the caregiver leaves. The child is also quickly comforted when the caregiver returns.
Describe an avoidant child attachment style.
is not distressed when the caregiver leaves. The child also avoids the caregiver when the caregiver returns.
Describe an ambivalent child attachment style.
is inconsolably upset when the caregiver leaves. The child will also both seek and reject caring contract when the caregiver returns.
Types of development (social, moral, physical, cognitive)
Physical: growth of the body and changes in the brain, sensory and motor skills, and levels of hormones.
Cognitive: how our mental processes and abilities to think and communicate change over time.
Socio-emotional: changes in how we understand ourselves, interact with others, and experience and regulate emotions.
Piaget’s Cognitive Development
Piaget proposed that we change how we think as we form new schemas, or ways of thinking about how the world works.
Assimilation: the process we use to incorporate new information into existing frameworks for knowledge.
Accommodation: the process we use to create new frameworks for knowledge or drastically alter existing ones to incorporate new information that otherwise would not fit.
What is Sensation?
the detection of physical energy emitted or reflected by physical objects. Occurs when energy in the external environment or the body stimulates receptors in the sense organs.
What is perception?
the process by which the brain organizes and interprets sensory information
What is Gestalt Psychology?
The founders of Gestalt psychology postulated a series of laws to explain how our brains group the perceived features of a visual scene into organized wholes.
Describe the sense of touch.
Penfield discovered that electrical stimulation of the primary somatosensory cortex could evoke the perception of touch in different regions of the body.
For the most sensitive regions of the body, such as the lips and fingers, a great deal of the cortex is dedicated to processing touch
Ivan Pavlov and Classical Conditioning
Pavlov observed that dogs began to salivate as soon as they saw bowls of food
Salivating at the sight of a bowl is not automatic
Behavior acquired through learning by association
What is a unconditioned stimulus?
a stimulus that naturally elicits a response without any prior learning (food)
What is a unconditioned response?
a response that does not have to be learned, such as a reflex (salivation)
What is a conditioned response?
a stimulus that elicits a response only after learning has taken place
What is a conditioned response?
a response to a conditioned stimulus; a response that has been learned.
What is a Neutral Stimulus?
anything not previously associated with the unconditioned response. (bell)
Alfred Bandura and Observational Learning
Observation of aggression: Bandura’s Bobo doll study (1961)
Group 1: watched film of adult playing quietly with Bobo, an inflatable doll
Group 2: watched film of adults attacking Bobo
The viewers of aggression were more than twice as likely to play aggressively.
What is positive reinforcement?
the addition of a stimulus to increase the probability that a behaviour will be repeated. Example: working harder after you receive a pay raise
What is negative reinforcement?
the addition of a stimulus to increase the probability that a behaviour will be repeated. Example: working harder after you receive a pay raise
