Key science skills Flashcards
psychology def:
the scientific
study of human mental
states and behaviour
science def:
a field and
practice that obtains
knowledge and
generates theories
through observation and
experiment
what is Empirical evidence?
information obtained
through direct and
systematic observation
or experimentation
what is non-science?
ideas
formed without empirical
evidence or the use of
scientific methods or
principles.
what is pseudoscience?
beliefs,
theories, and practices
that are mistakenly
regarded as, or claim to
be scientific, but are not
because they do not use
the methods of science
what is the scientific method?
a procedure used to obtain
knowledge that involves
hypothesis formulation,
testing, and retesting
through processes
of experimentation,
observation, measurement,
and recording
theory def:
a proposition or
set of principles that is
used to explain something
or make predictions about
relationships between
concepts
Aim def:
a statement
outlining the purpose
of an investigation
hypothesis def:
s a testable
prediction about
the outcome of an
investigation
variable def:
a condition
or component of an
experiment that can be
measured or manipulated
population def:
the group of people
who are the focus of the
research and from which
the sample is drawn
what is a Controlled experiment?
a type of investigation
in which the causal
relationship between two
variables is tested in a
controlled environment;
more specifically, the
effect of the independent
variable on the dependent
variable is tested while
aiming to control all other
variables.
what is the independent variable?
the variable for which
quantities are manipulated
(controlled, selected,
or changed) by the
researcher, and the
variable that is assumed
to have a direct effect on
the dependent variable
what is the Dependent variable?
the variable the researcher
measures in an experiment
for changes it may
experience due to the
effect of the independent
variable
what are controlled variables?
variables other than the
IV that a researcher holds
constant (controls) in an
investigation, to ensure
that changes in the DV are
solely due to changes in
the IV
what are investigation methodologies?
any of
the different processes,
techniques and/or types of
studies researchers use to
obtain information about
psychological phenomena
what are the different forms of psychological studies (investigation methodologies)?
- Controlled experiments
- Case studies
- Correlational study
- Classification and identification
- Fieldwork
- Literature review
- Modelling
- Product, process or system development
- Simulation
what is a case study?
an in-depth
investigation of an
individual, group, or
particular phenomenon
(activity, behaviour, event,
or problem) that contains
a real or hypothetical
situation and includes the
complexities that would
be encountered in the
real world
what is a correlation study?
a type of non-experimental
study in which researchers
observe and measure the
relationship between two
or more variables without
any active control or
manipulation of them
classification def:
the arrangement of
phenomena, objects,
or events into
manageable sets
identification def:
a process
of recognition of
phenomena as belonging
to particular sets or
possibly being part of
a new or unique set
what is fieldwork?
any research
involving observation and
interaction with people
and environments in realworld settings, conducted
beyond the laboratory
what is a Literature review?
the process of collating
and analysing secondary
data related to other
people’s scientific findings
and/or viewpoints in order
to answer a question
or provide background
information to help
explain observed events,
or as preparation for an
investigation to generate
primary data
what is modelling?
the construction and/or
manipulation of either a
physical model, such as
a small- or large-scale
representation of an
object, or a conceptual
model that represents a
system involving concepts
that help people know,
understand, or simulate
the system
what is Product, process, or
system development?
the design or evaluation
of an artefact, process, or
system to meet a human
need, which may involve
technological applications,
in addition to scientific
knowledge and procedures
what is a simulation?
a process of
using a model to study
the behaviour of a real or
theoretical system
what is the controlled group?
the group
of participants in an
experiment who receive
no experimental treatment
or intervention in order
to serve as a baseline for
comparison
what is the experimental group?
the group of participants
in an experiment who are
exposed to a manipulated
independent variable
(i.e. a specific intervention
or treatment)
what are Within-subjects designs
(also known as repeated
measures or withingroups design)?
an experimental design
in which participants
complete every
experimental condition
what are Between-subjects
designs (also known as
independent-groups
design or between-groups
design)?
an experimental
design in which individuals
are divided into different
groups and complete only
one experimental condition
what are Mixed designs?
an experimental design
which combines elements
of within-subjects and
between-subjects designs
what are the different types of feildwork?
- Direct observation
- Qualitative
- interviews
- Questionnaires
- Focus groups
- Yarning circles
what is a Sample?
a subset of the
research population who
participate in a study
what is Generalisable (also
known as generalisability)?
the ability for a sample’s
results to be used to make
conclusions about the
wider research population
sampling technique def:
the way a sample is
selected from the
population for a study
convenience sampling def:
any sampling technique
that involves selecting
readily available members
of the population, rather
than using a random or
systematic approach
