ures topic 1.
• Definition of psychology and an understanding of the 4 main components to this
definition and how they are practiced (see below). Note – default to the definition
we used in class which is a bit more precise than the one in the textbook.
• How psychology is practiced by
• By Specialized groups (specialization)
• By Perspective – each member of a specialized group has a perspective that
shapes the research method they use to answer the questions.
• BY Scientific Thinking (some of this was covered in week 2/topic 2
• What about other ways of thinking and critical thinking
• About Individuals - although some say historically WEIRD individuals
(Western, Educated, Industrialized, Rich, and Democratic) because a large
number of participant historically were male college students.
• Goal (basic vs applied – aka knowledge or treatment advances) - this part of
the lecture intersects with History
• History – the short and the long of it
• How does psychology help you – we consider happiness in class and psychology
careers and the book looks at studying strategies and careers as well.
• Consider the computational and data aspects of psychology and then how the study
of psychology crosses over many levels of analysis (1.10 and 1.11 in the book)
B. Research methods - Psychologist use scientific research methods
• Think like a scientist : Scientific research methods use
SCIENTIFIC THINKING.
• definitions, comparisons (and constrasts) between diferent types of
thinking: tenacity, intuition, common sense, rationalism, empiricism
and science.
• Relationship between truth and knowledge. Truth is true, knowledge is
tentative truth – right.
• Why is Scientific thinking the best method for finding knowledg
• t)
• Act like a scientist
• Define, compare and contrast the values and standards of science
• Consider WHERE each value and standard applies during the research
process. E.g., testing/falsifiability – apply to the design of the research
methods; parsimony applies to thinking about what theories to
“believe”; objectivity applies to theory development and systematic
observations....
• Include testable/falsifiable, accurate and precise, objective not
subjective, open-minded, generalizable, parsimonious, and ethical.
• Orderly steps and Systematic Methods
• Scientific thinking provides two research strategies (methods):
Theory testing & Theory Development
• Definition of theory and systematic observations
• Concepts and limitations of inductive and deductive logic
(rationalism)
• Scientific methods is about considering Variables
• Definition of variable
• What variables are measured and what variables are constructed
(constructs – mini theories)
• How do we measure variables in psychology?
• Definition of behavior and mental processes (which are measured and
which are measured by constructs?
• Orderly steps and systematic methods vary by research goal
• Define the research goals – to describe, to predict, to
explain
• Identify the number of variables studied by goal and
anys diference in how systematic methods are used for
each goal
• Identify what research designs (tools) are needed for
each goal.
• Systematic methods are organized (in the textbook and then
mentioned briefly in lecture) by
• Standardize procedures for all designs
• Control over the participants (sample) is necessary –
correlational and experimental designs
• Control over unintended variables – experimental
designs
C. Biopsychology
• Biopsychology as a perspective in psychology
• Theory (model) of Brain and Behavior (and mental processes).
Note direct vs indirect influence on behavior (and mental
processes)
• Metaphors
• Research designs and research tools.
• Specialization in behavioral neuroscience
• What kind of research questions they ask?
• The structure of the nervous system (focus on structures discussed in lecture, use
the book to supplement your understanding of the lectures)
• Central Nervous System
• Forebrain structures
• Midbrain structures
• Hindbrain structures
• Spinal Cord
• Peripheral Nervous
• Somatic structures
• Autonomic structures
• The function of the nervous system – broad strokes
• For each structure discussed (lecture) what broad function is
assigned to it. E.g., in the Somatic nervous system, the function
seems to be to collect information from sensors and send it to the
central nervous system (sensory systems) and to send information
from the central nervous system to skeletal muscles to coordinate
and produce behavior (motor system).
• The structure of the neuron and glial cells
• Dendrites
• Cell body
• Axon hillock
• Axon
• Myelin (oligodendrocytes or Schwann cells)
• Axon terminals and vesicles
• Synapse – a space between cells (as Ramon Y Cajal figured out) which
is defined as the space between a sending neuron (called the pre-
synaptic neuron) and a receive cell (either a neuron, muscle, or gland)
called the post-synaptic neuron (or muscle or gland, but mostly it’s a
neuron). Best picture of this in your book is 3.7.
• Astrocytes
• Microglia
• The function of the neuron
• For each structure above, identify the broad function.
• Consider how intracellular and intercellular communication
works in neurons to support information processing and
transmission
• Understand the processes of bioelectric signals and
biochemical signals necessary for information processing
in the nervous system.
• Best pictures/video about bioelectrical signaling
are found in section 3.2 of your textbook
• Best picture about biochemical signaling is 3.7.
• Recognize the function and structure of neural circuits
• You can recognize this out of our Model of biopsychology
• The structure of a neural circuit is that is a group of
neurons strong together to help transmit information
over long distances AND to help integrate information
from multiple sources of information. So in the CNS –
there are “tracts” (like railroad tracks)– axons all
travelling to other neurons over distances – function
to make sure the message gets there unchanged. And
there are “nuclei” or “ganglia”(like a train station)
where you find cell bodies dendrites and axon
terminals gather to share their messages, integrate
information to develop a new message to send to the
next ‘stop’.
• How does experience regulate the function of the nervous system to change
behavior and mental processes. This topic is covered in your book solely (see
section 3.13)
• How do psychoactive drugs work on the nervous system – we did not talk
about this in class, but you should review section 3.3 and see figure 3.8 to find
the answer. Make sure to find the definition of agonist and antagonist and
consider this diagram
• How do genes work with the nervous system to ‘control’ or influence behavior
and mental processes.
• Did you know? Some psychologists with a biological perspective specialize
further to focus on genetics. Their specialized field is Behavioral Genetics (so
a specialization of the biopsychology perspective).
• Remember that genes influence behavior and mental processes indirectly
(see diagram above)
• You should know the terms double stranded DNA helix and its relationship to
genes
• Also pay attention to the definition of gene, genotype, phenotype,
epigenetics, and heritability and the concept that genotype + environment
(experience) = phenotype.
• Make sure to read and understand sections 3.17 and 3.18 (examples of how
genes affect behavi
