Exam 1 Flashcards
Zeitgeist
Intellectual climate of the times (also the existing social, economic, and political factors)
Personalistic theory
View that progress and change in scientific history are attributable to the ideas of unique individuals
Naturalistic theory
Times make the person or makes possible the recognition for their ideas (Ex: Simultaneous discoveries)
Mechanism (& its time period)
Doctrine that natural processes are mechanically determined and capable of explanation by the laws of physics and chemistry (17th –>19thc)
Mechanism methods (3)
Observation, experimentation, and measurement
The clockwork universe
clock: “Mother of machines”/ Clocks made punctuality and orderliness very important, thus life became more predictable
Determinism
Belief that every act is determined or caused by past events
Reductionism
Doctrines that explains phenomena on one level (Ex: complex ideas) in terms of phenomena on another level (Ex: simple ideas)
Automata (& its pop century)
Popularized the notion that beings were just another kind of machine/ Pop. in EU during the 17th c.
People as machines (inspired by what 2 ideas/explain)
Clocks & automata/ Idea that human functioning and behavior were gov. by mechanical laws and thus could be measured experimentally & quantitatively
Empiricism
Pursuit of knowledge through obersvation and experimentation
___ (person) symbolized the transition the era of mod. psy
Descarte
Descarte on the mind and body problem
The question of the distinction between mental and physical qualities
D: Mind and body are ___ entities, mind ____ body and ___ ___
different, influences, vice versa
D: bc the ___ is composed of matter, it must possess those characteristics common to all matter
body
Reflex action theory and its theorist
Descarte: Idea that an external object (stimulus) can bring about an involuntary resp. (reflexes)
Innate ideas & its theorist
Descarte: Arise from the mind or consciousness/ independent of sensory experiences of external stimuli
Note worthy contributions from Descarte (5)
Mechanistic conception of the body/ theory of reflexes/ mind-body interaction/ localization of mental functions in the brain/ doctrine of innate ideas
Who’s essay marked the beginning of British empiricism?
John Locke’s understanding human behavior
Locke’s key ideas (7)
mind blank slate, sensation ideas, reflection,simple ideas, theory of association, primary and secondary qualities
Locke’s mind as blank slate
no innate ideas, instead, in terms of learning and habit experience
Sensation ideas
Derived from direct sensory input from physical objects (operate on the mind and the mind operates on the sensations, reflecting on them to form ideas)
Reflection
Based on impressions already experienced through the senses/ sensations are the forerunner/ in reflecting, we combine sensations and combine them to form abstractions and other high level ideas AKA reductionism
Simple ideas
Arise from both sensation and reflection and are received passively by the mind/ cannot be analyzed or reduced/ can be combined to form complex ideas
Complex ideas
can be analyzed or resolved into their simpler component
Theory of association & its theorist (& its significance)
Locke: Notion that human knowledge results from linking simple ideas to complex (significant in thinking of mind as machine)
Primary qualities
Exist in an object whether or not we perceive them (Ex: size, shape of building)
Secondary qualities
Depend on the experiencing person (Ex: color, odor, sound, and taste) (If we don’t bite into the apple, its taste does not exist)
Mentalism and its theorist
Berkley;empiricist: All known is a function of a mental phenomena and person (all experience is subjective) God is the perceiver
Berkley: ___ perception not a simple sensory experience, but an ___ of ideas that must be ___
depth, association, learned
When did physiology become an experimentally oriented discipline and under who’m?
1830’s/ Muller
Research on brain function: Mapping from the inside (3 methods)
Extirpation, clinical method, and electrical stimulation
Extirpation and practitioner
Flourens: Researcher attempts to determine the function of a given part of the brain by removing or destroying it and observing the changes in behavior
Clinical method and its practitioner
Broca: post humous examination of brain structures to detect damaged areas assumed to be resp. for behavioral conditions that existed before person died
Electrical stimulation & its practitioners
Fristsch and Hitzig: technique for exploring cerebral cortex with weak electric current to observe motor response
Research on brain functions, mapping from outside: (practitioner?) confirmed existence of __ and ___ matter in the brain, nerve fibers connecting each side of the brain to the ___ side of the spinal cord, and the fibers connecting both ___ of the brain
Gall: white, gray, opposite, halves
spirit of __ dominant in 19th c. physiology and 19th c phl
mechanismse
The beginnings of experimental psy (4 individuals)
Helmholtz, Weber, Fechner, and Wundt
Q: Why experimental psy in Germany? (Ax2)
The German approach to sci (inductive approach/ science defined broadly)/ reform movement in GR universities (academic freedom/ well equipped labs/well paid researchers
Helmholtz emphasized which two approaches?
mechanism/determinism
Helmholtz contributions to psy(4)
Yielded conduction speed of neural impulse, demonstrated thought and action don’t occur at same time, one of earliest experimentation and measurement for psychophysical processes, young-helmholtz theory of color vision
Weber and his contributions (2)
Two point thresholds, just noticeable difference
Two-point threshold
distance between 2 points that must be spanned before subjects report feeling 2 diff. sensations (1st systematic, experimental demonstration of the concept of threshold)
Just noticeable difference (JND)
Smallest difference that can be detected between 2 physical stimuli
Fechner and subject of interest
mind and body quantitative relationship
How did Fechner propose one measure the relat. bw mind and body?
measure the change in stimulation to measure changes in sensation
Fechner’s two proposed ways to measure sensatons
Determine whether a stimulus is present or absent/ sensed or NOT sensed & measure the stimulus in intensity at which subjects report the sensation to first occur
Absolute threshold (definition and theorist)
Fechner: measure the stimulus intensity at which subjects report feeling the sensation first occurs
