Psych 375 Exam 1 Flashcards
Lessons from the Past
Ancient Views.
-illness caused by evil spirits/ bewitchment
-treated with trephination (open brain up to get rid of the bad spirits)
-demons and punishment by the gods cause illness in Egypt
Roots of Non-Western Medicine
Traditional Chinese Medicine- founded on principle of internal harmony( life force that flows within everyone, when balance is messed up that is when you get sick), Qi (vital energy or life force that flows within every person), Acupuncture, herbal therapy, meditation.
Ayurveda (longevity-knowledge)- oldest known medical system, health is a balance of bodily humors (doshas)
Health and Illness: The Middle Ages
Epidemic- disease that spreads rapidly within a community at the same time (localized)
Pandemic- disease spreads over a larger area, such as multiple continents or worldwide.
Plague- bacterial disease carried by rodents that occurred during the Middle Ages (poor sanitation in streets)
Illness is god’s punishment for evil doing “mystical beliefs”
Health and Illness: Post Renaissance
Shift from mysticism to the biological causes of disease
Germ theory of disease-idea that disease is caused by microorganisms, bacteria, viruses that invade body cells.
many advances in medical knowledge and procedures driven by inventions such as microscope and x-ray.
Health and Illness: 20th Century
Biomedical model- the idea that illness aways has a physical cause *what is missing? Everything else- psychological, social, or access factors.
-Embraces reductionism (complex phenomena derive ultimately from a single primary factor)
-Pathogen= a virus, bacterium, or some other microorganisms that causes a particular disease (germs)
-Psychosomatic medicine= outdated branch of medicine focused on the diagnosis and treatment of physical disease caused by emotional conflicts.
-started trend toward modern view of illness and health as multifactorial.
-conversion convertors= mental converts into physical forms
Emergence of Health Psychology
1978: APA establishes the Dickson of health psych with 4 goals.
1. To study scientifically the causes or origins of specific diseases, that is, their etiology (why do people engage in risky behaviors)
2. To promote health (increase knowledge and understanding)
3. To prevent and treat illness (biomedical)
4. To promote public health policy and improvement of the health care system (minimize risks for people when they get sick)
The Biological Context
Every thought, mood, and urge is a biological event.
Evolutionary Perspective=
-adaption and reproductive success drive trait and behavior development
-biology and behavior do not occur in a vacuum and constantly interact (biology doesn’t predict everything. people with PTSD are quick to startle and perceive a threat when there’s none)
-most important traits are epigenetic (human genome project tried to predict cancer but they couldn’t because there are other factors)
Life Course Perspective=
-Age related aspects of health and illness
-considers leading causes of health (car accidents and heart disease) overall and by age group.
The Psychological Context
Health and illness are subject to psychological influences (stress is inevitable but how do we tackle that?)
-Appraisal and interpretation of stressful experiences, attitude and treatment effectiveness, and psychological interventions
Positive Psychology- studies the importance of subjective well being (cognitive and emotional evaluations of a person’s life)
The Social Context
Ways people think about, influence, and relate to one another and the environment.
Birth cohort: group of people born at about the same time who experience similar historical and social conditions (ex. covid, 2008 recession, flint water crisis)
The Sociocultural perspective
Sociocultural perspective-considers how social and cultural factors contribute to health and disease.
Culture- enduring behaviors, values, and customs that a group of people transmit from one generation to the next.
Ethnic group-large groups of people who tend to have similar values and experiences because they share certain characteristics.
Gender Perspective
Gender: socially constructed roles and behaviors a given society considers appropriate for each sex.
Sex: Assigned at birth, refers to a person’s biological status as male or female, associated with physical characteristics (e.g. chromosomes, hormones, anatomy)
Men, compared to women, are more likely to make unhealthy food choices, be overweight, drink more, ignore illness symptoms, have higher rate of injury
->lower life expectancy
Critical thinking: The Basis for Research
What is critical thinking?
A questioning approach to info and argument that:
- doesn’t blindly accept conclusions
-examines underlying assumptions
-evaluates evidence and scrutinize conclusions
Consumers of Research
Evidence-based medicine-use of current best evidence in making decisions about the care of individual patients or the delivery of health services. Includes:
1. best research evidence (that we have)
2. Clinical expertise (what experience/why we think that)
3. Patient characteristics, culture, and preferences
Effectively evaluate the evidence claims of a salesperson, journalist.
(find, read, and evaluate behind important health policies, therapies, and treatment approaches)
- autism and vaccinations: vague conclusions/no stats
Health Misinformation
Infodemic- False information amplified by social media platforms, blogs, vlogs, etc
(ex. during covid-19 pandemic was also an infodemic)
The Dangers of “Unscientific” thinking
Confirmation bias (jumping to conclusions)- a form of faulty reasoning in which our expectations prevent us from seeing alternative explanations for our observations.
Epidemiology
Epidemiology- scientific study of the frequency, distribution, and causes of a particular disease or other health outcome in a population. (how it spreads across an area)
-obesity graph shows that obesity is more prevalent in the south, midwest. possibly due to the culture in the south, or linked to socioeconomic status
Descriptive Studies
-Often conducted in the field or lab (gathering info that can result in new info)
-include case studies, surveys and interviews and naturalistic observation
-permit the gathering of in-depth information that often leads to new hypotheses
Difficulties
-no direct control over variables
-can’t determine causality (b/c not manipulating any variable)
-subject to bias of observer
-single cases may be misleading
Correlation Coefficient
-statistical measure of the relationships between two variables (exercise goes up so does fitness)
-direction= r value ranges from -1(negative or inverse correlation) to +1 (positive correlation
-strength= r value ranges from 0 (no relationship between variables) to 1 (“perfect” correlation), regardless of sign (closer to the line)
- correlation (association) vs. causation
Experimental studies
-usually conducted in the laboratory
-statistical comparison of experimental and control groups
-experimental groups- participants who receive the condition or treatment of interest
-control group- comparison group of participants who receive a different treatment, or no treatment.
The Experiment Variables
Independent Variable- the factor in an experimenter manipulates; the variable whose effects is being studies.
Dependent variable- the factor in an experiment that may change in response to manipulations of the independent variables
Random assignment- assigning research participants to groups by chance to minimize preexisting differences
control variables- remain consistent among the groups
