Exam 2 Study Guide Flashcards
elementism
the belief that complex mental or behavioral processes are composed of or derived from simple elements and that t best way to understand these processes is first to find the elements of which they are composed.
gestalt psychology
school of thought that believes all objects and scenes can be observed in their simplest forms. Sometimes referred to as the late of simplicity, the theory proposes that the whole of an object or scene is more important than its individual parts.
Three founders of gestalt
max wertheimer
kurt koffka
Wolfgang kohler
max wertheimer
german psychologist had an idea that our perception ar structured in ways that sensory stimulation is not. that is, our perceptions are different from the sensations that comprise them.
kurt koffka
in 1922, he wrote an article about perception and how it relates to gestalt.
gestalts were interested in learning about thinking, perception, development, learning, and much more.
for him, the geographical environment is the physical environment, whereas the behavioral environment is our subjective interpretation of the geographical environment
Our own subjective reality governs our actions more than the physical environment does.
wolgang kohler (1887-1967)
he saw flaws in IQ tests and in what exactly they measure.
emphasized the processes that influence the tests achievements.
studied learning in chimpanzees and chickens, and how that is tied into the
phi phenomenon
illusion that light is moving from one location to another
perceptual constancy
the way we respond to objects as if they were the same, even though the stimulus themselves might be varied greatly
figure ground relationship
division of the perceptual field into two parts (the figure that is being attended to, and the ground, which is diffuse, and is everything not being attended to)
principle of continuity
the tendency to experience stimuli that follow some predictable pattern as a perceptual unit
principle of proximity
the tendency to perceptually group together stimuli that are physically close
principle of similarity
tendency to perceive as units stimuli that are physically similar to one another
principle of closure
the tendency to perceive incomplete objects as complete
gestalt explanation of learning
there is a problem, disequilibrium, and then a motivation to solve the problem and equilibrium
detour problem
animal could see its goal but could not reach it directly
insightful learning
learning that involved perceiving a solution to a problem after a period of cognitive trial and error
productive thinking
insight based reasoning, understanding solutions rather than memorizing
wertheimer believed that solving a problem is an intrinsic reinforcement
reaching an understanding involves many aspects of learners
german and british traditions in psychology
the german tradition went from rationalism with Spinoza and Leibniz to physiology
the british tradition was empiricism, which transferred to evolutionary theory with darwin and malthus
why were Bessel’s discoveries important?
Friedrich Bessel (1784–1846), who speculated that the error had not been due to incompetence but to individual differences among observers. Bessel set out to compare his observations with those of his colleagues and indeed found systematic differences among them. This was the first reaction-time study, and it was used to correct differences among observers.
he showed that there were differences between individuals in reaction time studies, which made it clear that these were not incompetencies.
Bell-Magendie Law
There are two types of nerves: sensory nerves carrying impulses from the sense receptors to the brain and motor nerves carrying impulses from the brain to the muscles and glands of the body.
After Bell and Magendie, it was no longer possible to think of nerves as general conveyers of vibrations or spirits. Now a “law of forward direction” governed the nervous system.
clearly sensation and movement involves the brain.
Charles Bell (1774–1842)
British physiologist, Discovered, in modern times, the distinction between sensory and motor nerves.
Operating on rabbits, Bell demonstrated that sensory nerves enter the posterior (dorsal) roots of the spinal cord and the motor nerves emerge from the anterior (ventral) roots. Bell’s discovery separated nerve physiology into the study of sensory and motor functions—that is, into a study of sensation and movement. Bell’s finding was significant because it demonstrated that specific mental functions are mediated by different anatomical structures.
François Magendie (1783–1855)
French physiologist, discovered, in modern times, the distinction between sensory and motor nerves.
doctrine of specific nerve energies
Each sensory nerve, no matter how it is stimulated, releases an energy specific to that nerve.
Johannes Muller (1801-1858)
german physiologist. Expanded the Bell–Magendie law by demonstrating that each sense receptor, when stimulated, releases an energy specific to that particular receptor. This finding is called the doctrine of specific nerve energies.
Following Bell’s suggestion, Müller demonstrated that there are different types of sensory nerves, each containing a characteristic energy, and that when they are stimulated, a characteristic sensation results. In other words, each nerve responds in its own way no matter how it is stimulated. For example, stimulating the eye with light waves, electricity, pressure, or by a blow to the head will all cause visual sensations.
