Pyschology Flashcards
what is replication
a study that is conducted using the same or similar methods as the original investigation
why do psychologists replicate studies
in order to evaluate whether consistent results can be obtained
What is direct/exact replication?
A scientific attempt to exactly copy the scientific methods used in an earlier study in an effort to determine whether the results are consistent
What is Conceptual replication?
researchers re-test the same theoretical idea or hypothesis repeatedly, but use different populations, different ways of manipulating variables, different ways of measuring variables, or using different study designs.
What is replication + extension?
combine results from prior studies with results from a new study specifically designed to replicate and extend the results of the prior studies.
What is P-hacking?
the manipulation of data analysis until it produces statistically significant results, compromising the truthfulness of the findings.
is it even possible to perfectly replicate more complex
studies?/ How can we be sure the replication is unbiased?
Yes, but there are several things that are needed to do so
(psychological realism, resources, and more)
Is there a limit on how long ago a study was to be
replicated?
no. Any study can be chosen to be replicated, and
folks tend to have different attitudes toward replications when they
focus on newer vs older research
Why does the replication process, when/if it fails, make
other scientists criticize the original study versus the replicated one?
We should be critically evaluating the strengths
and weaknesses of both studies
what are the proper ways to decide whether the replication
is legitimate to overturn the original experiment. Does the replication
have to be exactly the same or few changes are allowed, and if
allowed, then how much change is allowed?
First, we should have multiple replications before we throw
anything out. And second, that’s a question that should be decided
by the scientific community (of the field being tested) and the
researchers involved
Did replication support a lot of experiments as correct?
Yes! Another recently published replication project (in psych and
economics) replicated about 2/3s of the selected studies
Developmental Psychology
The study of changes in physiology, cognition, emotion, and
social behavior across the lifespan.
Longitudinal designs
Cross-sectional Designs
Dynamic systems theory
development is a self-organizing
process, where new forms of behavior emerge from consistent interactions between a person/organism and their
environments (including cultural factors)
Descriptive Research
Observational studies (Naturalistic Observation, Archival Analyses, Ethnography), Case Studies/Interviews, Self-Report Surveys/Correlational Studies
Descriptive Statistics
Mean/average, median, mode, variability, standard deviation
Inferential Statistics
Help us infer whether differences between groups reflect true
differences or if they are probably due to chance
How do we think critically about research and
other claims?
by thinking of an ideal study for
the topic and comparing; also by looking for sources,
evaluating those sources, and then evaluating each step
in the research process
How do we design research studies to test our
ideas?
We plan multiple studies, starting with descriptive/correlational and moving up to experimental to balance the advantages and disadvantages of each type of design and recognize that each type of study answers a different question
How do we know research is strong & replicable?
We know it when it uses large sample sizes & good
data practices and when it is replicated lots of times
Ideal Scientific Method & Research Process
theory (what makes good theories), hypothesis, study, data, results, confidence, return to theory
Internal, external, and construct validity
incl. random selection/sampling, random assignment, double-blind, confounds, generalizability, operational definition
Data
reliability, accuracy, conducted with ethics (IRB), descriptive
statistics, inferential statistics, significant differences, meta-analyses
Statistical deviance
infrequency
Emotional distress
Unhappiness
Cultural deviance
violate norms
Dysfunction
Difficulties with daily living
Psychological disorders are
maladaptive
To be considered a mental disorder, a condition must have 4 things
it must be statistically uncommon, violate cultural norms, cause emotional distress, create dysfunction or difficulty with daily living
Naturalistic Observation
is a method that involves observing subjects in their natural environment.
Archival Analyses
any data that are collected prior to the beginning of the research study.
Ethnography
the scientific description of the customs of individual peoples and cultures.
Antisocial Personality Disorder
is a deeply ingrained and rigid dysfunctional thought process that focuses on social irresponsibility with exploitive, delinquent, and criminal behavior with no remorse
Bipolar Disorder
a mental illness that causes unusual shifts in a person’s mood, energy, activity levels, and concentration.
Major Depressive Disorder
a mood disorder that causes a persistent feeling of sadness and loss of interest
Narcissistic Personality Disorder
A disorder in which a person has an inflated sense of self-importance
Schizophrenia
a serious mental illness that affects how a person thinks, feels, and behaves. People with schizophrenia may seem like they have lost touch with reality, which can be distressing for them and for their family and friends.
Borderline Personality Disorder
a mental illness that severely impacts a person’s ability to manage their emotions. This loss of emotional control can increase impulsivity, affect how a person feels about themselves, and negatively impact their relationships with others.
Which of the following patients (untreated) seems to have schizophrenia?
A. Carl, who performs actions repeatedly and without being able to stop
B. Mona, who wants to sleep all the time and has suicidal thoughts
C. Olivia, who is hyperactive and acts like she’s at the top of the world
D. Darren, who sometimes hears voices and worries it means someone is out to get him
D.
Women tend to touch and be touched more than men
(Floyd, 2010)
Women also perceive interpersonal touch more positively in
both their affective and evaluative responses toward their
partners
(Fisher, Rytting, & Heslin, 1976)
As children, same-gender pairs tend to touch each other more
often than cross-gender pairs; as adults, however, cross-
gender touch becomes more frequent
(Williams & Willis, 1978; Willis & Hoffman, 1975; Daniels, 1978; Remland, Jones, & Brinkman, 1995; Bossen et al., 2012)
Couples in San Juan, Puerto Rico touched an average of 180 times
per hour
Couples in London, England touched an average of 0 times per
hour
Coffee-shop study (Jourard, 1966)
Overall, much higher rates of touch than in the coffee-shop study
Northeast Asian couples touched significantly less than Southeast
Asian, Caribbean-Latino, Northern European, or US couples
Airport gates study (McDaniel & Andersen, 1998)
Social behavior and social contact are the norm or baseline for
humans, and when we lack this contact, we show poor
responses to stress
Social Baseline theory
Handholding reduces the body’s physiological responses to
threat, even when your partner is a stranger (though to a
lesser extent)
Social Baseline Theory
