Q

the absolute threshold

A

the smallest amount of stimulus energy necessary to detect a stimulus. For example, the smallest amount of light energy that enables a person to just barely detect a flash of light would be the absolute threshold for seeing that light.

Q

the difference threshold

A

(called DL from the German ‘Differenze Limen’, which is translated as ‘difference threshold’) is the smallest difference between two stimuli that a person can detect.

25
affordances
behaviours that are possible in a given environment
26
ventral pathway
the pathway in the brain that processes "what" information about the environment
27
dorsal pathway
the pathway in the brain that processes "where" information about the environment
28
neuron
the basic cell of the brain
29
dendrites
extensions from neurons that receive chemical messages (neurotransmitters) from other neurons
30
axon
an extension from the neuron nucleus where an electrical impulse in the neuron occurs
31
synapse
a space between neurons where neurotransmitters are released and received
32
single-cell recording
a brain activity recording technique that records activity from a single neuron or small group of neurons in the brain
33
electroencephalography (EEG)
a brain recording technique that records the activity of large sections of neurons from different areas of the scalp
34
magnetoencephalography (MEG)
a brain recording technique that records activity of large sections of neurons from different areas of the scalp using a large magnet that is placed over the head
35
transcranial magnetic stimulation (TMS)
a method of temporarily stimulating or suppressing neurons using a magnetic field
36
transcranial direct current stimulation (tDCS)
a method of temporarily stimulating or suppressing neurons using an electrical current
37
magnetic resonance imaging (MRI)
a technique to image the internal portions of the body using the magnetic fields present in the cells
38
positron emission tomography (PET)
a technique that images neuron activity in the brain through radioactive markers in the bloodstream
39
functional magnetic resonance imaging (fMRI)
an MRI technique that images brain activity during a task
40
shadowing task
a research procedure where subjects are asked to repeat (i.e.: shadow) a message over headphones
41
cocktail party effect
an effect of attention where one's focus changes abruptly due to a salient stimulus (such as one's name) in the environment
42
dual-task method
a research procedure where subjects are given two tasks to perform at once - to compare with performance on one task alone - to examine interference due to the second task
43
inattentional blindness (aka change blindness)
failure to notice a change in the environment
44
Simon effect
interference in response due to inconsistency between the response and the stimulus
45
Stroop task
a research procedure where subjects are asked to name the colour of printed words where some words are colour words that conflict with the print colour showing interference in the naming task
46
automatic processing
processing that is not controlled and does not tax cognitive resources
47
controlled processing
processing due to an intention that consumes cognitive resources
48
deductive reasoning
making and evaluating arguments from general information to specific information
49
inductive reasoning
making and evaluating arguments from specific information to general information
50
syllogistic reasoning
a process by which a conclusion follows necessarily from a series of statements
51
conditional reasoning (propositional reasoning)
a process by which a conclusion follows from conditional statements ("if...then" statements)
52
dual-process framework
the idea that cognitive tasks can be performed using two separate and distinct processes
53
representativeness bias
a bias in reasoning where stereotypes are relied on to make judgements and solve problems
54
availability bias
bias in reasoning where examples easily brought to mind are relied on to make judgements and solve problems
55
framing bias
a bias in reasoning where the context in which a problem is presented influences our judgement
56
well-defined problem
a problem that has a clearly defined goal state and constraints
57
ill-defined problem
a problem that lacks a clearly defined goal state and constraints
58
functional fixedness
focusing on how things are typically used and ignoring other potential uses in solving a problem
59
insight
suddenly realising the solution to a problem
60
mental set
a tendency to use the same set of solutions to solve similar problems
61
analogical transfer
using the same solution for two problems with the same underlying structure
62
algorithm
a prescribed problem-solving strategy that always leads to the correct solution in problems with a single correct solution
63
heuristic
a problem-solving strategy that does not always lead to the correct solution
64
means-ends strategy
a problem-solving strategy that involves repeated comparisons between the current state and the goal state
65
hill-climbing strategy
a problem solving strategy that involves continuous steps towards the goal state
66
working-backward strategy
a problem-solving strategy that involves beginning with the goal state and working back to the initial state
67
IDEAL framework
a step-by-step description of problem-solving processes
