Psych 1 Exam pt 2

Question 1

EEG (electroencephalogram)

Answer 1

an amplified recording of the waves of electrical activity sweeping across the brain’s surface. These waves are measured by
electrodes placed on the scalp.

Question 2

MEG (magnetoencephalography)

Answer 2

a brain-imaging technique that measures magnetic fields from the brain’s natural electrical activity.

Question 3

PET (positron emission tomography)

Answer 3

a technique for detecting brain activity that displays where a radioactive form of glucose goes while the brain performs a
given task.

Question 4

MRI (magnetic resonance imaging)

Answer 4

a technique that uses magnetic fields and radio waves to produce computer-generated images of soft tissue. MRI scans show
brain anatomy.

Question 5

fMRI (functional MRI)

Answer 5

a technique for revealing blood flow and, therefore, brain activity by comparing successive MRI scans. fMRI scans show brain
function as well as structure.

Question 6

Schemata/Schema

Answer 6

mental models of the world that people use to guide and interpret their experiences

Question 7

Assimilation

Answer 7

fitting new objects events, etc, into existing schema

Question 8

Accommodation

Answer 8

modifying a schema to fit new events, objects, etc

Question 9

Piaget’s Stages and the ages in which they come

Answer 9

Sensorimotor - 0-2
Preoperational - 2-7
Concrete Operations - 7-12
Formal Operations - 12+

Question 10

Sensorimotor

Answer 10

understand the world through senses and motor actions, develops object permanence. [Child begins to interact with the environment]

Question 11

Preoperative

Answer 11

Understand intuitive relations and thinking is dominated by perception [Child begins to represent the world symbolically] playing pretend

Question 12

Concrete Operations

Answer 12

• Can do mental/logical
  operations
  – Show evidence of
  elemental reasoning
• Understand reversibility
• Can do conservation &
  classification tasks
  [children learn rules such as conservation]

Question 13

Formal Operations

Answer 13

• Can do abstract &
  hypothetical
  reasoning
• Can reason
  contrary to
  experience
• Found only in
  people’s areas of
  experts
  [can transcend concrete situations and think about the future]
