New cards
Freuds principal ideas and why he inspired controversy
Treated mental disorders and believed in the Unconscious self and was the creator of psycho analysis, sparked controversy as he believed that sexual desires were the basis of daily action
2
New cards
Unconscious self
desires, thoughts, memories that are well below the surface of conscious awareness
3
New cards
Psychoanalysis
treatment of mental disorders.
4
New cards
Watson's influence of psychology
Proposed removing the study of consciousness to only study observable behaviors, forfather of behaviorism
5
New cards
Behaviorism
a theoretical orientation based on the premise that scientific psychology should study only observable behavio
6
New cards
Skinner's contribution
radical behaviorist that believed free will was a lie with everything being controlled by outside forces.
7
New cards
humanism
believed Psychoanalysis and behaviorism were dehumanizing, they believed in a more optimistic approach.
8
New cards
what historical events contributed to the emergence of psychology
WW1 and WW2 where soldiers struggled from PTSD
9
New cards
trends emerging in the 1950s-1960s
(decision making, reasoning, problem solving, and language) became popular with new medical technology advancements to scan the brain. This returned to the study of consciousness and how behaviors are shaped by brain function, injuries to the brain, heredity, and neurotransmitters.
10
New cards
Why has western psychology shown more interest in cultural varibles
1.Advances in communication travel and international trade have “shrunk” the world 2. The ethnic makeup of the western world has increased.
11
New cards
Evolutionary psychology
(examines behavioral processes in terms of their adaptive value for members of a species over the course of many generations.) the basic ideas being behaviors are different in different species from evolutionary processes
12
New cards
Positive psychology
(uses theory and research to better understand positive, adaptive, creative, and fulfilling aspects of human existence) Developed by Martin Seligman after saying his daughter is grumpy and realizing he has a negative approach to life and so does psychology.
13
New cards
Growth of pcychology
The growth of psychology comes from the increase in interest in the field with a drastic rise in the American Psychological Association (APA) members from 35 to 75,000. Most have private practices, then working in colleges or universities, with clinical work being third.
14
New cards
Developmental psychology
Looks at development throughout life but mainly focus on the adolescent stage

Cognitive psychology-
Focuses on “higher” mental processes such as memory, reasoning, information processing, language, problem solving, etc
21
New cards
Psychometrics
is concerned with the measurement of behavior and capacities, usually through the development of psychological tests. Determined to test personality, intelligence, and a wide range of abilities
22
New cards
Personality-
interested in finding a person's constituency in behavior, which represents personality.
23
New cards
The three unifying themes
Psychology is Empirical.
Psychology is theoretically diverse
Psychology evolves in a social historical context
24
New cards
Empiricism
knowledge should be collected through observation
25
New cards
Theory-
is a system of interrelated ideas (multiple theories in psychology)
26
New cards
social historical context
Psychology's past and current studies are used in psychology making it an ever growing amount of information while using the history in modern practice
27
New cards
4 unifying themes in psychology
Behavior is determined by multiple causes
Behavior is shaped by cultural heritage
Heredity and environment jointly influence behavior
People's experience of the world is highly subjective
28
New cards
Behavior is determined by multiple causes
As psychology has developed more and more information of what governs behavior appear, people judge you based on one behavior
29
New cards
Culture
Shared customs, beliefs, values, norms, institutes, and other products of the community that are transmitted socially across generations
30
New cards
Critical thinking
is purposeful, reasoned, goal-directed thinking that involves problem-solving, formulating inferences, working with probabilities, and making careful thought out discussions.
31
New cards
Goals of the scientific enterprise.
Measurement and description
Understanding and prediction
Appliance and control
32
New cards
Measurement and description
We have to find a way to measure results
33
New cards
Hypothesis:
tentative statement about the relationship between two or more variables
34
New cards
Variables:
Any measurable conditions, events, characteristics, or behaviors that are controlled and observed
35
New cards
Appliance and control
Information collected will have some practical use in the real world
36
New cards
Steps in a scientific experiment
Formulate a hypothesis
Design a study
Collect the data
Analyze the data and draw conclusions.
37
New cards
Experiment
is a research method in which the investigator can manipulate variables under carefully controlled conditions and observes in any changes occur to the second variable as an result
38
New cards
Independent variable,
Variable being manipulated
39
New cards
Dependent variable
Variable measured for change based on the independent variable.
40
New cards
Experimental group,
consists of subjects who get special treatment in regard to the independent variable
41
New cards
Control Group,
simular group not given the special treatment
42
New cards
Correlation
exists when two variables relate to each other
43
New cards
Postive correlation
change in the same direction
44
New cards
Negative correlation
have inverse relationship
45
New cards
correlation variable
-1-1
46
New cards
Naturalistic observation
The major strength of naturalistic observation is that it allows researchers to study behavior under conditions that are less artificial than in experiments.
47
New cards
Case studies
Case studies are particularly well suited for investigating certain phenomena, especially the roots of psychological disorders
48
New cards
Surveys
Surveys are often used to obtain information on aspects of behavior that are difficult to observe directly. Surveys also make it relatively easy to collect data on attitudes and opinions from large samples of participants
49
New cards
Replication in research
is important to ensure the accuracy of research.
50
New cards
Deception
. Deception is used in psychological research to help mitigate the placebo effect and have more accurate findings.
51
New cards
Controversy surrounding animal research
Animal research is criticized for exposing animals to adverse conditions that would be unacceptable to subject people to. Defenders of animal research say that without it many important breakthroughs would never have been made
52
New cards
Subjectivity of experience:
The subjectivity of personal experience became apparent in the discussion of methodological problems, especially placebo effects and experimenter bias. When research participants report beneficial effects from a fake treatment (the placebo), it’s because they expected to see these effects.
53
New cards
PsycINFO
The abstracts are concise—about 75 to 175 words. They briefly describe the hypotheses, methods, results, and conclusions of the studies. Each abstract should allow you to determine whether an article is relevant to your interests. If it is, you should be able to find the article in your library (or to order it) because a complete bibliographic reference is provided. The PsycINFO database can be accessed online through most academic libraries or directly via the Internet.
54
New cards
Lesioning
destroying a piece of the brain to study the effects it has on function. It's Usually done by putting an electrode in and running a high frequency current to destroy that part of the brain.
55
New cards
Electrical stimulation
using an electrode with a weak current to activate the part of the brain it is in. It doesn’t have the same electrical impulse as nature current in the brain but will still activate it
56
New cards
CT (computerized tomography) scan
is a computer-enhanced X-ray of brain structure. Multiple X-rays are shot from many angles, and the computer combines the readings to create a vivid image of a horizontal slice of the brain
57
New cards
MRI (magnetic resonance imaging) scan
uses magnetic fields, radio waves, and computerized enhancement to map out brain structure. MRI scans provide much better images of brain structure than do CT scans
58
New cards
PET (positron emission tomography)
radioactive markers to map chemical activity in the brain over time. They provide color-coded maps that show where brain activity is present during different events/activities
59
New cards
Occipital Lobe:
Back of the head, responsible for vision and visual processing
60
New cards
Parietal Lobe
Forward of the occipital lobe, Registers touch sensation and also responsible for body positioning in space and integrating visual input
61
New cards
Temporal Lobe
Below the parietal lobe, responsible for auditory processing. Damage to the temporal lobe can impair speech and language comprehension
62
New cards
Frontal Lobe
Front, devoted to muscle movement. More intricate movements like fingers have more space devoted to them
63
New cards
Evidence of brains plasticity
Research shows that the structure of the brain can change based on aspects of experience, like the centers of visual and motor coordination changing structurally when mastering juggling or the structures in reasoning changing when going to law school.

The brain can also change based on destruction of physiology, like the part of the brain used to control an amputated finger then being restructured to work with the second and fourth finger. In some blind people, areas of the visual occipital lobe are rededicated to auditory processing
Neurogenesis (formation of new neurons) occurs in adults in the olfactory bulb (smell) and the hippocampus (learning and memory).
64
New cards
split brain analysis
We used to believe that the left hemisphere of the brain was responsible for most intricate and detailed language tasks, and that the right side was much less useful. Using studied on individuals who had the connection between the two brains severed to treat severe epilepsy, researchers found that the truth was much more nuanced, and that while the left hemisphere is indeed better at language, but the right wasn’t more primitive or less useful, instead being skilled in puzzle/problem solving and visual-spatial tasks, including discriminating colors, arranging blocks, and recognizing faces

Research methods in Heredity
RESEARCH METHODS
“In family studies, researchers assess hereditary influence by examining blood relatives to see how much they resemble one another on a specific trait. If heredity affects the trait under scrutiny, researchers should find trait similarity among relatives. Furthermore, they should find more similarity among relatives who share more genes. For instance, siblings should exhibit more similarity than cousins.”

“In twin studies, researchers assess hereditary influence by comparing the resemblance of identical twins and fraternal twins with respect to a trait. The logic of twin studies hinges on the genetic relatedness of identical and fraternal twins (see Figure 3.21). Identical (monozygotic) twins emerge when a single fertilized egg splits for unknown reasons. Thus, they have exactly the same genetic blueprint; their genetic overlap is 100%. Fraternal (dizygotic) twins result when two separate eggs are fertilized simultaneously. Fraternal twins are no more alike in genetic makeup than any two siblings born to a pair of parents at different times. Their genetic overlap averages 50%.”

Adoption studies assess hereditary influence by examining the resemblance between adopted children and both their biological and their adoptive parents. If adopted children resemble their biological parents on a trait, even though they were not raised by them, genetic factors probably influence that trait. In contrast, if adopted children resemble their adoptive parents, even though they inherited no genes from them, environmental factors probably influence the trait.

“contrary to early expectations for genetic mapping techniques, it appears that scientists are not likely to identify a handful of specific genes that control intelligence, extraversion, musical talent, or other behavioral traits, including psychological disorders. That reality does not mean that genetic mapping studies have no role to play in unraveling the hereditary bases of behavior. Scientists remain optimistic. The challenge will be to identify collections of genes that each exert very modest influence over aspects of behavior and to figure out how these genes interact with environmental factors (Halldorsdottir & Binder, 2017; Heine, 2017).”

. Epigenetics is the study of heritable changes in gene expression that do not involve modifications to the DNA sequence. The effects of certain genes can be inhibited or stopped by chemical changes at the cellular level, and these changes can be heritable even though the genes don’t change. Believed to be partially responsible for psychological disorders and addictive tendencies.
