Then given the evil dictator, where he places mines on ea. road leading to his castle that are sensitive to large groups of people. Most people can solve by giving solution to break up the large group into multiple small ones, and each smaller group simultaneously charges from the different roads. When shown that the same concept can be applied to the chemo (shooting it at the patient from multiple angels and locations) people don't realize it.

Cocktail Party Effect: Leaky Filter
-You are at a party with friends and all of a sudden you hear your name/hometown or something that is meaningful to you and that grabs your attention. -The ability to focus on one stimulus while filtering out other stimuli has been called the cocktail party effect, because at noisy parties people are able to focus on what one person is saying even if there are many conversations happening at the same time. -Treisman's (1964) Attenuation Model: All messages go through a filter, some are weakened (leaky filter) but you notice if it is important to you -Selection happens in two stages 1. Atenuator -Analyzes the incoming message in terms of (1) its physical characteristics, (2) its language, and (3) its meaning 2.

binding
Donald Broadbent
birth of modern cognition; applied work with the Navy in the UK; interested in understanding the limits of attention; selective attention; filter model: filter located between incoming sensory memory and short-term memory storage that works together with a buffer, enabling the subject to handle 2 kinds of stimuli presented at the same time; one of the inputs is allowed through the filter, and the other waits in the buffer for later processing
fMRI
blood flow increases in areas of the brain activated by a cognitive task. The measurement of blood flow is based on the fact that hemoglobin, which carries oxygen in the blood, contains a ferrous (iron) molecule so it is magnetic. If a magnetic field is presented to the brain, the hemoglobin molecules line up like tiny magnets. fMRI indicates the presence of brain activity because the hemoglobin molecules in areas of high brain activity lose some of the oxygen they are transporting. This makes the hemoglobin more magnetic so it responds more strongly to a magnetic field ~determines brain activity in various areas of the brain by detecting changes in the magnetic response of hemoglobin ~Advantage: no radioactive tracer needed & is good for localization of function
Working memory:
book's definition: limited-capacity system for temporary storage and manipulation of info for complex tasks such as comprehension, learning, and reasoning .
functional magnetic resonance imaging (fMRI)
brain-imaging technique that measures the amount of oxygen in the blood in various areas of the brain (oxygen-rich blood is an index of brain activity); magnetic field surrounds the participant's head and produces changes in the oxygen atoms; while the participant performs a cognitive task, a scanning device takes a photo of the oxygen atoms; preferable to a PET scan because it is less invasive, no injections/radioactive materials are necessary; can measure activity that occurs fairly quickly so it's more precise in identifying the exact time sequence of cognitive tasks (not the ones we perform very quickly) does not provide precise information about a person's thoughts
event-related potential (ERP) technique
brain-imaging technique that records brief fluctuations in the brain's electrical activity in response to a stimulus; provides precise information about the timing of brain activity; electrodes are placed on a person's scalp to record electrical activity generated by a group of neurons located directly underneath the skull; can identify electrical changes over a very brief period of time in a specific region of the brain habituation: N1 wave pattern in auditory cortex and frontal regions; paradigm: repeated tone presentation attentional capture: MMN-mismatch negativity pattern in frontal regions; elicited by noticeable change in repeated stimulus controlled attention: for focus during encoding the tones; P300 wave pattern
single-cell recording technique
brain-imaging technique used for animals; an insertion of a thin electrode into or next to a single neuron measures electrical activity generated by that cell to study characteristics of an animal's brain and nervous system; the goal is to identify the variations in a stimulus that produce a consistent change in a single cell's electrical activity; cells provide a mechanism for recognizing specific patterns (i.e., letters of the alphabet); cells in cat's brain fired only when the cat was presented with a particular stimulus

~neurons that are specialized to pick up info from the environment such as the neurons in the eye, ear, and skin ~have an axon but have specialized receptors that pick up info from the environment
resting potential
~no signals in the neuron ~the inside of the neuron has a charge that is 70 mV more negative than the outside and this difference continues as long as the neuron is at rest
physiological levels of analysis
~perception: chemical processes- neurons activated- brain structures activated- groups of brain structures activated ~memory: chemical processes- neurons activated- brain storage- storage activated
Charles Gross
~presented stimuli to anesthetized monkeys and he discovered that neurons in the temporal lobe respond to complex stimuli
David Hubel and Weisel
~presented visual stimuli to cats and determined which stimuli caused specific neurons to fire ~each neuron in the visual area of the cortex responds to specific types of stimulation presented to a small area of the retina ~feature detectors
Edgar Adrian
~recorded electrical signals from single sensory neurons ~discovered that action potentials travel down the axon without changing height or shape (makes it ideal for sending signals over distances)
microelectrodes
~small shafts of hollow glass filled with a conductive salt solution that can pick up electrical signals at the electrode tip and conduct these signals back to a recording device ~a recording electrode has its recording tip inside of the neuron ~ a reference electrode is located some distance away so that it is not affected by the electrical signals ~the difference in charge between the recording and reference electrodes is fed into a computer and displayed
The neuron doctrine
~the idea that individual cells transmit signals in the nervous system and that these cells are not continuous with other cells as proposed by nerve net theory ~Ramon y Cajal
Ramon y Cajal
~used the Golgi stain (a thin slice of brain tissue is submerged in a solution of silver nitrate & pics were created in which fewer than 1%of the cells were stained) ~studied the tissue from brains of newborn animals b/c the density of cells was smaller w/ the golgi stain ~ with the combined techniques Cajal was able to see that neurons are not continuous
recording electrical signals
~when the axon or nerve fiber is at rest the meter records a difference in potential between the tips of the two electrodes of -70millivolts and this value stays the same as long as there are no signals in the neuron (resting potential) ~the inside of the neuron has a charge that is 70 mV more negative than the outside and this difference continues as long as the neuron is at rest

In Lindsay's "misinformation effect" experiment, participants saw a sequence of slides showing a maintenance man stealing money and a computer. This slide presentation included narration by a female speaker who described what was happening in the slides as they were shown. Results showed that the misinformation effect was greatest when MPI presentation was
Persistence of vision
When light from a flashlight is moved quickly back and fourth on a wall in a darkened room , it can appear to observers that there is a trail of light moving across the wall, even though physically the light is only in one place at any given time.
