16

endorphins

New cards
17

18

What are the molecules that are similar enough to a neurotransmitter to bind to its receptor sites on a dendrite and mimic that neurotransmitter's effects called?

agonists

New cards
19

New cards
22

The master gland of the endocrine system is the

pituitary gland

New cards
23

When the "Jim twins," identical twins separated at birth, were reunited 38 years later, surprising similarities were discovered. Although they had married women of the same name, named their sons and dogs the same names, one should be cautious before attributing these similarities to genetic factors because

any two strangers are likely to share coincidental similarities.

New cards
24

Hormones are the chemical messengers of the

endocrine system

New cards
25

Studies of identical twins who had been reared apart most clearly highlight the importance of ________ in personality development.

New cards
27

A brief electrical charge that travels down the axon of a neuron is called the

action potential

New cards
28

Mandy came home late. As she reached to turn on the kitchen light, her hand brushed against something unexpected. Her adrenal glands, as a part of the "fight-or-flight" response, released epinephrine and norepinephrine, which increased her heart rate and blood pressure. Even after she realized it was just the curtain, her excited feelings lingered. This example illustrates

that endocrine messages tend to outlast the effects of neural messages.

New cards
29

Evolutionary psychologists are most likely to be criticized for

providing hindsight explanations for human behaviors.

New cards
30

To identify which specific brain areas are most active during a particular mental task, researchers would be most likely to make use of a(n)

fMRI

New cards
31

Psychoactive drugs interfere with normal neural transmission. Where does this interference take place?

synapse

New cards
32

Adopted children are more likely to demonstrate levels of agreeableness and extraversion, more similar to that of their biological parents than their adoptive parents. This finding suggests that personality traits are more strongly influenced by

genes than by the home environment.

New cards
33

If a professor accused you of cheating on a test, your adrenal glands would probably release ________ into your bloodstream.

epinephrine

New cards
34

Which statement best reflects current psychology's understanding of the relationship between nature and nurture?

nature via nurture

New cards
35

Researchers found that women rated men higher as potential long-term mates when they spent more time looking at baby pictures. This finding suggests that

women prefer men who express interest in caring for joint offspring.

New cards
36

An all-or-none response pattern is characteristic of the

initiation of neural impulses.

New cards
37

Why is it incorrect to say that 50 percent heritability of intelligence means that the cause of your intelligence is 50 percent genetic and 50 percent environmental?

because heritability accounts for variations among people, not in specific individuals

New cards
38

Botulin is a poison with a molecular structure so similar to acetylcholine (ACh) that it blocks the effects of ACh in synapses, making botulin which kind of molecule?

antagonist

New cards

How is the hypothalamus involved in sleep?
