Question

1. identify the following: a. hallucinogens: b. depressants: c. stimulants: d. near - death experience: e. tolerance: f. withdrawal: 23. when does drug use become an addiction? 24. what are the potential consequences of excessive and/or prolonged drug use? module 1.4a the brain: neuroplasticity & tools of discovery 25. explain what biological psychologists focus their research on.

Explanation:

a. Hallucinogens are drugs that cause hallucinations, altering a person's perception of reality.
b. Depressants slow down the central - nervous system, reducing arousal and anxiety.
c. Stimulants speed up the central - nervous system, increasing alertness and energy.
d. A near - death experience is a profound psychological event that some people report having after a close brush with death.
e. Tolerance occurs when the body becomes accustomed to a drug, requiring higher doses to achieve the same effect.
f. Withdrawal is a set of symptoms that occur when a person stops using a drug to which they have become physically dependent.
Drug use becomes an addiction when it leads to compulsive drug - seeking behavior, despite negative consequences.
Potential consequences of excessive and/or prolonged drug use include physical health problems (e.g., organ damage), mental health issues (e.g., depression, psychosis), social problems (e.g., relationship breakdowns, job loss).
Biological psychologists focus on how biological processes (such as genetics, the nervous system, and hormones) influence behavior and mental processes.

Answer:

a. Drugs causing altered perception.
b. Drugs slowing central - nervous system.
c. Drugs speeding central - nervous system.
d. Profound event after near - death.
e. Body's need for higher drug doses.
f. Symptoms on drug cessation.
Drug use is addiction when compulsive with negative consequences.
Consequences: physical/mental/social problems.
Biological psychologists focus on biological influences on behavior.
