A
- Biased decision making and referrals limits the SP’s ability to support all students or even the right students
- the Wait to Fail model often means we are intervening when students are already too far behind
- It does not meaningfully inform intervention as many areas assessed cannot be directly changed, and we have a hard time understanding whether interventions are working

49
What is Brief Experimental Analysis?
involves rapidly exposing a student to different treatment conditions and assessing each condition/s effect on a target behaviour
50
What is a basic tenant of ABA research>
behavioural treatments should be techological and conceptually systematic, meaning that their principles and procedures should be fully specified and should eliminate, reverse, or weaken the variables actually influencing the occurrence of problem behaviour
51
What is systematic formative evaluation?
ongoing evaluation of instructional programs based on direct repeated measures of student outcomes
52
How does postnatal brain development happen?
through selective subtraction of neurons, not addition
humans are born with most of their neurons already developed
53
What two areas of the brain develop new neurons after birth

1. impairs production of neurons
2. impairs migration of neurons to their final destinations
3. increases apoptosis - programmed cell death
55
How does the slow development of the prefrontal cortex relate to adolescence?
1. inhibition of impulses is lacking, which many attribute teen's risky and antisocial behaviours to
1a - however, the most risky and antisocial acts are done by a small population with a history of such things
2. better explanation - lack of inhibition of impulses leads to desire to engage in exciting, thrill-seeking events especially if there is peer praise
56

often used to measure stages of sleep or seizure activity
limited to measuring neurons at the surface of the brain
62
What does a magnetoencephalography (MEG) do?
measures tiny changes in magnetic activity evoked by brain activity
slightly better spatial resolution than EEG
limited to measuring neurons at the surface of the brain
63

the change in brain activity following a stimulus
often measured with an EEG
64
What does single-photon-emission computed tomography (SPECT) do?
a radioactive isotope is injected into the blood and then sensors surrounding the head are used to trace blood flow in the brain
useful for localizin brain tumours or the effects of brain trauma
65
What does a computed axial tomography (CAT) scan do?
a dye is injected into the bloodstream to increase visual contrast, then x-rays are passed through the head and recorded by detectors on the other side in a rotating fashion
useful for localizing brain tumours or the effects of brain trauma
carry some risk because of exposure to radiation
66
What does a positron emission tomography (PET) scan do?
a radioactively labeled chemical such as glucose is injected into the bloodstream, and then since active brain areas use more glucose, we can measure relative levels of brain activity
useful for localizing brain tumours or the effects of brain trauma
carry some risk because of exposure to radiation
67
What does magnetic resonance imaging (MRI) do?
applies a strong magnetic field to align the axes of rotation of all the water molecules to the head. Then a brief radiofrequency pulse is applied and removed, causing the water molecules to release energy and the MRI measures it
can show tumours and other abnormalities
requires absolute stillness from patient, so its not great for kids
68
what does a functional MRI do?
measures hemoglobin molecules instead of water
used to measure activity in relative brain areas during an activity of some sort
69
How do genes impact expression of disorders?
- no such thing as a "single gene" for any disorder
- most likely reason for heritability is copy number variants (having a gene that influences brain development deleted or copied too many times)
70
What is heritability?
an estimate of the fraction of the observed variation in some characteristic within a population that is due to the genetic variation within that population
varies from 0 to 1
71
What is epigenetics?
changes in gene expression without changes in the DNA sequence, often due to experiences or environment in the child, or in either parent
- shared family traits can be either genetic or epigenetic
72
What is the evidentiary relationships between environment and genetics?
If the environment is satisfactory, then genetic variations control much of the outcome
If the environment is poor, the variations in how poor overwhelm the effects of genetic variation
73

the ability to simultaneously store and process information
77
What is in the multicomponent model of working memory?
1. articulatory loop - for storing verbal information
2. visuospatial scratch pad for storing spatial information
3. central executive that directs processes in the articulatory loop and visuospatial scratchpad
78
What is executive function?
a suite of general purpose control mechanisms that modulate the operation of various cognitive subprocesses and thereby regulate the dynamics of human cognition
79
What are the 3 EF?
1. shifting - moving from one stimulus or task to another
2. inhibition - suppressing irrelevant stimuli or tasks in the service of focusing on relevant ones
3. Updating - adding and deleting representations in WM
80
What is long term memory?
memory that is slow and error-prone in the encoding of representations and the retrival of those representations
there is no limit on LTM
81
What are the relevant systems in LTM to school psych?
1. Declarative
2. Episodic
3. Semantic
4. Procedural
82
What is declarative memory?
encodes ifnormation that you "know that" and can consciously retrieve
factual
two subgroups: episodic and semantic
83
What is episodic memory?
encodes events that a person has experienced
Has two parts
1. Semantic content - facts of memories; directly recalled
2. contextual content - internal state and local context during the memory; indirectly retrieval
84
What is semantic memory?
encodes facts and concepts
a collection of episodic memories without the contextual context (ie you recall episodic memories en masse and the contextual content cancels out, so that you're left only with semantic)
85
What is procedural memory?
encodes information that you "know how"
retrieved and applied unconsciously
86
How are procedural memories encoded?
Encoded as productions, each of which has a condition and action aspect
1. Condition aspect - specifies a pattern of representations in WM that must be present for the production to match
2. Action aspect - the doing - when a production matches, we execute action, which results in addition or deletion of representations in WM
87
What is the power law of practice?
key empirical finding of procedural memory
the time to perform a cognitive skill decreases with practice, specifically as a power function of the number of times a skill has previously performed
88
What is automaticity?
the ability to execute an action quickly and accurately when practices
89
What is controlled processing?
directed from the top down by goals, is flexible and can be modified by novel tasks, and it is effortful and places heavy demands on WM
90
What is automatic processing
directed from the bottom up by inputs, inflexible and difficult to modify for novel tasks, but effortless in making light demands on WM
91
What is compilation?
According to ACT theory, this is how with practice, a complex skill encoded in declarative LTM comes to be encoded in procedural LTM
92
Why does compilation improve performance?
1. Retrieving from declarative LTM is slow and accurate, but retrieving productions is fast and accurate
2. Following compilation, the steps do not need to be maintain in WM, only the results (partial products) of executing them
93
What is product composition?
a process where a sequence of multiple productions is chunked into a single production
94
What is instance theory of automatization?
with practice, the results of performing a complex skill come to be encoded as an instance in declarative LTM, where they can can be quickly and accurately retrieved
95
What is the difference between compilation (ACT theory) and instances (instance theory)?
ACT understands automatic processing as reflecting a shift to productions encoded in procedural memory, whereas the instance theory presents it as a shift to simple retrieval from declarative memory

verbatim recall of information at a later time
101
What is induction?
discovery of new, abstract knowledge
better happens when spaced practice is used
102
What is learning through interleaving?
learning is best when multiple learning tasks are interleaved
leads to worse performance during instruction but must better retention when tested later
103
What is learning through processing?
the kind of processing performed when enxoding new information impacts later retrievability
supported by 3 effects
1. levels of processing
2. transfer-approproate processing
3. generation
104
What is the levels of processing effect?
the more deeply or semantically information is processed at encoding, the more accurately it can be retrieved later
105
What is the transfer-appropriate processing effect?
memory processing is best when the processing performed at encoding matches the processing required at retrieval
106
What is the generation effect?
memory performance is better when the encoding task requires generation rather than just passive readingW
107
What is learning through testing?
tests can be used to promote learning not just assess learning
108
What is the testing effect?
following initial study of new information, taking a test produces better long-term retention than additional studying
109
What is the goal of transfer in learning?
applying information learned in one setting and for one purpose to other settings and for other purposes
110
What are the transfer assumptions of the education system?
Knowledge and skills learned
a) in one class will transfer to other classes

c) in school will transfer to the workplace
111
What is learning through generalization?
when people learn abstract representations that can be retrieved later in novel settings and applied to solve novel problems
112
What is analogical problem solving?
requires retriving the solution to a source problem that has previously been solved and applying (or transferring) it to a new target problem
113
What is learning through contrast?
transfer is promoted when people learn the critical distintions between the concepts of a domain
114
What is learning through telling?
transfer is most likely to occur when constructivist instruction approaches such as contrasting cases are followed by direct instruction approaches such as lecture
115
What is learning through failure?
when first learning a new domain, there is value in struggling with complex problems rather than beginning with predigested lectures and simple problems, even if the struggles are unsuccessful and the complex problems are unsolved
might only be effective for students with sufficient prior knowledge
116
What are three differences between cognitive psychology and school psychology?
1. C is a basic science, SP is an applied science
2. CP more aligned with experimental approach, SP more aligned with correlational

118
What are attitudes?
the tendency to evaluate an entity with some degree of favour or disfavour
119
What is the process of attitude formation?
involved affect or emotion, cognition, and behaviour
emotions are formed through conditioning processes, simple exposure to a stimulus, and social learning involving observations and modeling
120
What is attribution theory?
the study of how individuals assign internal or external causation to situations and how they act on this information

127
What is epidemiology?
the systematic study of the ongoing prevalence of a problem, disease, or diagnosis and all of the associated risk and protective factors connected to that problem
128

130
What is a focus in school psychology in the life course developmental science domain?
Risk and protective factors
risk factors - conditions, attributes, or behaviours that increase the lieklyhood of a negative outcome

140
What are the fundamental premises of a tiered prevention approach?
1. All children can benefit from universal supports
2. the risk of progressing to a more intensive service needs can me mitigated for many children by intervening earlier with less intensive supports
3. lack of response to less intensive services can better identify those most in need of intensive support
141
