Measuring the effects of drugs on human behaviour

Question 0

Rating Scales?

Answer 0

collecting subjective data in a systematic, quantitative manner.

Question 1

Subjective effects?

Answer 1

This is introspection. A person is asked their personal exp of the drug. (how they feel etc)

Question 2

Visual Analog Scale?(VAS)

Answer 2

make a mark on a line between two extreme alts to indicate how the variable applies to them.

Question 3

Profile of Mood States (POMS)

Answer 3

a paper and pencil test that asks subjects to indicate on a five point scale how each of the 72 adjectives applies to them at a particular moment. (anxiety, depression, anger, vigour, fatigue confusion, friendliness and elation) INTERNAL STATE.

Question 4

Addiction Research Center Inventory ( ARCI )

Answer 4

drug profile ( mood and physical changes) is matched against that of a known drug’s profile.

Question 5

Liking Scale?

Answer 5

participant is asked to indicate how much the drug is liked.

Question 6

Drug State Discrimination?(humans)

Answer 6

Given instructions initially that they are getting either drug a , or drug b (placebo). Then they are given random unexplained exposures and asked to identify which they were given usually with the promise for reward with the correct answer.

Question 7

Absolute Threshold?(perception)

Answer 7

the lowest value of a stimulus that can be detected via sense organ. (measure of absolute sensitivity of the sense organ)
( the point at which you recognize stimuli…)

Question 8

Difference Threshold (perception)

Answer 8

the ability of a sense organ to detect a change in level or locus of stimulation.
(high threshold= intensity of stimulus must be increased to be detected, Low threshold= a sense has become more sensitive).
(how high of a difference does there have to be in simuli before you notice a change)

Question 9

Critical Frequency at Fusion?

Answer 9

if the speed at which a light flickers is increased there will be a point that the light appears steady.

Question 10

Simple Reaction Time (RT)- MOTOR PERFORMANCE.

Answer 10

tests where the subject must make a response , like pressing a button as fast as possible, after a noise or light has turned on.

Question 11

Complex Reaction Time (CRT)

Answer 11

there are several possible responses and several different signals associated with each one.

Question 12

Hand-Eye Coordination- Pursuit rotor

Answer 12

instructed to hold the end of a stylus on a spot contained on a rotating disk. The total time the participant is able to hold the stylus on the moving spot is a measure of HEC.

Question 13

Mackworth Clock Test?( Attention and Vigilance test)

Answer 13

look at a large circular dial like a radar screen. A clock hand moves around this dial in a step by step fashion at regular intervals. Occasionally, the hand will move two steps at once rather than one step. The participant must detect when this happens and hit a button.

Question 14

Short term memory?

Answer 14

a limited amount of info while it is being used for some purpose.

Question 15

Long Term Memory?

Answer 15

more or less permanent and can last for years. Memories are transferred from short term to here via consolidation process.

Question 16

N-back test (short term memory)

Answer 16

a series of letters or pictures are shown one at a time. When a target stimulus arrives up such as an X the individual must recall the last shown image. (1 back, 2 back, 3 back etc)

Question 17

Long term is further split into :
A. Implicit
B. Explicit- episodic as well.
Define each.

Answer 17

A. procedural memory; memory of how to do things.
B. declarative memory; the ability to recall pieces of info.
B ii. Episodic memory: remember events that have happened to us.

Question 18

Free Recall (long term memory test)

Answer 18

asked to remember a list of words or objects and after a period of time they must reproduce the items on the list.

Question 19

Crude Recall (long term test)

Answer 19

shown an array of items and asked to identify the ones that were on the original list they had to memorize. (m/c)

Question 20

Disinhibition?

Answer 20

when drugs interfere with a persons ability to withhold or inhibit actions.

Question 21

Go-No Go Task (inhibition test)

Answer 21

must respond quickly to one stimulus but most not respond to a different stimulus.

Question 22

Go-stop tasks (inhibition test)

Answer 22

asked to respond quickly to a stimulus but a stop signal will appear at sometime and they most stop responding completely. The longer the interval before the stop cue, the harder it is to stop.
