Quiz 2 Cognitive Psychology

What is the gap between the end of a neuron's axon and the dendrites or cell body of another neuron known as?

Synapse

A 10-month-old baby is interested in discovering different textures, comparing the touch sensations between a soft blanket and a hard wooden block. Tactile signals such as these are received by the __________ lobe

parietal

When the axon is at rest, the inside of the neuron has a charge that is 70 millivolts more negative than the outside. This difference will continue as long as ____

the neuron is at rest

Which parts of neurons are also known as a "nerve fiber"?

axon

The key structural components of neurons are the ____

cell body, dendrites, and axons

The study of the physiological basis of cognition is known as ____

cognitive neuroscience

Early studies of brain tissue that used staining techniques and microscopes from the 19th century described the "nerve net." These early understandings were in error in the sense that the nerve net was believed to be ___

continuous

Brain imaging has made it possible to ___

determine which areas of the brain are involved in different cognitive processes

The idea that specific cognitive functions activate many areas of the brain is known as _____

distributed representation

Neurons that respond to specific qualities of objects, such as orientation, movement, and length, are called ___

feature detectors

When recording from a single neuron, stimulus intensity is represented by the _____

firing rate of the action potentials

The fusiform face area (FFA) in the brain is often damaged in patients with ____

prosopagnosia

If the intensity of a stimulus that is presented to a touch receptor is increased, this tends to increase the __________ in the receptor's axon

rate of nerve firing

The idea that an object could be represented by the firing of a specialized neuron that responds only to that object is called _____________.

specificity coding

Edgar Adrian studied the relationship between nerve firing and sensory experience by measuring how the firing of a neuron from a receptor in the skin changed as he applied more pressure to the skin. He found that _____.

the rate of nerve firing increases as he increased the pressure
