T/F: According to the Ecological approach to perception, information for action can be directly perceived without the need for memory or knowledge.
True
Neurotransmitters bind to receptors on the dendrite to open ion channels. Positive ions flow into the cell and trigger depolarization. This electrical impulse traveling down the axon is called the __________.
action potential
Wundt's procedure in which trained participants describe their experiences and thought processes in response to stimuli presented under controlled conditions is known as:
analytic introspection
The cognitive revolution:
occurred rapidly, within a period of a few years, in response to the attacks on Skinner and the development of computers

expectation-based perceptual sets
What is NOT an argument supporting Behaviorism?
information processing theories are oversimplified
According to Ecological Theory, ____________ are patterns/relationships that stay the same despite transformations over time and space.
invariants
What is a criticism of analytic introspection
it produces variable results from person to person
Recording from single neurons in the brain has shown that neurons responding to specific types of stimuli are often clustered in specific areas. These results support the idea of...
localization of function
When conducting an experiment on how stimuli are represented by the firing of neurons, you notice that neurons respond differently to different faces. For example, Arthur's face causes 3 neurons to fire, with neuron 1 responding the most and neuron 3 responding the least. Roger's face causes 3 different neurons to fire, with neuron 7 responding the least and neuron 9 responding the most. Your results support ____ coding.
sparse
Which object recognition theory cannot account for differences in the style, position, and orientation of a stimulus?
template theory
What 2 events helped start the Cognitive Revolution?
1. the introduction of the IBM personal computer 2. Army research on training pilots during WWII
The notion that every stimulus pattern is seen in such a way that the resulting structure is as simple as possible is called the law of...
Pragnanz
_____ is emitted from a light source, and reflects off surfaces of the environment to create _____.
Radiant light; Ambient light
If the intensity of a stimulus that is presented to a touch receptor is increased, this tends to increase the ____ in the receptors axon
Rate of nerve firing
What is the key function of dendrites?
Receives signals from other neurons
________ theory suggests that objects are recognized by the spatial configuration of their basic geometric shapes.
Structural
what are 3 arguments that support Behaviorismt?
- introspection is not a suitable technique to understand the mind - mental processes can never be known or measured - external behavior produces observable data
What are 2 limitations of Experimental Cognitive Psychology?
1. Laboratory settings may not replicate real world behavior 2. Studying behavior does not directly study brain functioning
What is the correct order of these philosophies from oldest to newest? - introspection - cognitive revolution - behaviorism - nativism
1. Nativism 2. Introspection 3. Behaviorism 4. Cognitive Revolution
What DOES characterize the information processing approach to the study of cognition?
- depicts the mind as processing information in a sequence of stages - involves the use of computers as a metaphor to understand human cognition - traces the sequence of mental operations involved in cognition
What is true about optic flow?
- Optic flow is the transformation of the optic array due to movement - Different patterns of optic flow specify different events in the environment - Birds use optic flow to determine when they will collide with something
Perception researchers claim that the retinal image is "impoverished," and must be enriched through cognitive processes. How is the retinal image impoverished?
- The retinal image is upside-down and reversed - The retinal image is distorted/stretched
What is NOT an example of a physical regularity?
Angled orientation
Which object recognition theory claims that the perceiver generates hypotheses about what caused a stimulus, and then chooses the most probable one?
Bayesian theory
What does the field of Neuropsychology study?
Behavior of people with brain damage
A researcher presents rats with painful stimulus whenever they walk to a specific corner of their cage, and records the rat's movement in the cage for 1 week. This research aligns with which historical perspective?
Behaviorism
What is the key function of somas?
Completes metabolic functions
What is using a computer program to predict how humans will perform on a decision-making task an example of?
Computational Cognitive Science
Which functional network is most active when a participant is not involved in a specific task?
Default mode network
Functional Magnetic Resonance Imaging (fMRI) has made it possible to:
Determine which areas of the brain are involved in different cognitive processes
What is NOT a research method used to determine functional areas in the brain?
Event-related potentials
T/F: The Ecological approach to visual perception would be considered a top-down approach.
False
Neurons that respond to basic qualities of objects, such as orientation, movement, and length, are called:
Feature detectors
You look at a rope coiled on a beach and are able to perceive it as a single strand because of the Gestalt principle of...
Good continuation
What does NOT characterize the information processing approach to the study of cognition?
IP emphasizes stimulus-response relationships in cognitive processes
What best describes the inverse projection problem?
Many configurations of the world can create a single retinal image
Rene Descartes introduced a philosophy of dualism in the 1600s that separated ___ and ___.
Mind; Body
What DOES NOT reveal the impact of top-down processing on perception?
Optical invariants
What is the key function of a fMRI?
to measure blood flow in the brain
What is the key function of a ERPs?
to measure electrical activity at the scalp
What is the key function of a TMS?
to temporarily stimulate or inhibit regions of the brain
If a word is identified more easily when it is in a sentence than when it is presented alone, this would be an example of processing?
top-down
Members of a security team are stationed on rooftops surrounding a large city plaza before a scheduled rally. Suddenly, three team members in different locations radio in to the command center, each stating that they have spotted a suspicious box on the ground with a pipe coming from the top.
