Perspectives On Psychopathology Complete
Questions With Correct Answers
\Q\.Compare and contract single factor vs interactionist explanations/theories. -
ANSWERS✔-Single-factor explanation: Attempts to tract the origins of a particular
disorder to one factor. Interactionist explanations: View behaviour as the product
of the interaction of a variety of factors, generally make more satisfactory theories
in describing mental disorders.
\Q\.Describe the null hypothesis. - ANSWERS✔-Proposes that the prediction made
from the theory is false. Sets up an experiment to reject (or fail to reject) the null
hypothesis instead of proving the theory.
\Q\.What is the purpose of experiments in relation to theories? - ANSWERS✔-To
eliminate an alternative theory or explanation which opposes the theory being
experimented on.
\Q\.How do theories gain strength? - ANSWERS✔-Theories don't gain strength
from supporting evidence but from rejecting alternative explanations.
, \Q\.What are the general aims of theories? - ANSWERS✔-Explain the etiology of
the problem behaviour. (Etiology: The causes or origins.) Identify the factors that
maintain the behaviour. Predict the course of the disorder. Design effective
treatments.
\Q\.What is reductionism? What does reductionism thinking ignore? -
ANSWERS✔-Actions of the whole are said to be causes by one or another of the
component parts. Reductionist thinking ignores the rather obvious possibility that
human behaviour in all its forms is a product of an array of features (biological,
developmental, environmental, personal choice, cultural, and so on) interacting.
\Q\.What do biological views propose? - ANSWERS✔-Biological views propose
that disordered behaviour or thinkings is related to dysfunctions in or damage to
the brain (the central nervous system, or CNS), problems of control of one or
another aspect of the peripheral nervous system (that is, the autonomic nervous
system or the somatic nervous system), or malfunctioning of the endocrine
system.
\Q\.What are neurotransmitters? - ANSWERS✔-The chemical substances that
carry the messages from one neuron to the next in the complex pathways of
nervous activity within the brain.
\Q\.Describe the gene-environment interaction. - ANSWERS✔-A common view is
that most, if not all, behaviours are a product of an interaction between genetic
contributions as well as environmental factors such as society, culture, and
personal experience. Gene-environment interactions: A term used to describe the
phenotypic effects (i.e., observable characteristics) that are due to interactions
between the environment and genes. Genes may influence behaviours that
