4What is WMand Why is it Important?
5What is Working Memory?
- A system for temporary storage and manipulation
of information,necessary for a wide rangeof
cognitive tasks - The ability to keep information in your mind for
a short period of time (seconds), and be able
to use the information in your thinking
6Characteristics of Working Memory
- WM is where learning takes place
- Problem solving and trying to comprehend text
are WM in action - WM is the interface between input and output
- WM
- Uses information available from STM
- -or-
- Retrieves information from LTM
- Performs some action on these two stores of
information - Then stores the new product in LTM
- -or-
- Uses it to construct an expression or response
-or- both

8Theories of WM
- Most widely accepted theory is Baddeleys
multi-component model (Baddeley, 1986) - Defines four aspects of WM
- Phonological loop
- Stores and rehearses speech-based information
- Visual spatial sketchpad
- Encodes, stores, organizes, and manipulates
visual images and visual-sensory information - Central executive
- Attentional controlling system
- Maintains task activities and blocks task
interference - Episodic buffer
- Links visual/verbal information to LTM
9Why is WM Important?
- Working memory is used for
- Controlling attention
- Resisting distraction
- Complex thinking
- Organization
- Problem solving
- Remembering tasks
10WM is an Essential Function in Everyday Life
- Processes all stimuli we encounter
- Delegates it to the different parts of our brain
that can take action - Allows us to block out unnecessary information
- Keeps us updated on whats happening and keeps
us focused on what matters
11Working Memory Processes and Organizes Your Life
The search engine of your brain
12Working Memory
- Plays a critical role in cognitive processing and
learning - WM integrates and manipulates information as it
processes - Input from the environment that has entered
through the brains sensory and perceptual areas - -and-
- Information retrieved from long-term stores of
knowledge
13Why Is Working Memory Important?
- Essential for most academic areas, including
- Reading (especially comprehension)
- Math (especially problem solving)
- Written expression
- Test taking
- WM predicts academic learning
- 10 15 of children have a WM deficit
- WM deficits found in many disability profiles
- Early identification through efficient assessment
is imperative to identify at-risk students
14WM and Academic Learning
15WM Capacity in School-Age Children
- Supports learning
- Associated with reading (Gathercole Pickering,
2000) and math ability (Geary et al., 2004) - Useful prospective indicator of academic
performance - Predicts attainment on national assessments at
ages 7, 11, 14 (e.g. Gathercole, et al., 2004
St-Clair Thompson Gathercole, 2006) - Adds unique variance above and beyond measures of
IQ (Gathercole, Alloway, Willis Adams, 2006) - Unlike IQ, free from SES and other crystallized
knowledgethat has been built from home, school
and social experiences (e.g. Engel, Santos
Gathercole, 2008)
16WM Capacity in School-Age Children
- Children with poor working memory make poor
academic progress (Gathercole Alloway, 2008) - Of 300 children with poor WM
- 83 scored poorly on either reading or math tests
- The vast majority scored poorly in both areas
17WM Capacity in School-Age Children
- Important for successful learning in individual
classroom activities (Gathercole Alloway, 2008)
- WM loads of many classroom activities are high,
so children with poor WM - Forget crucial information
- Fail to successfully complete tasks
- This leads to frequent lost learning
opportunities,and consequently slow rates of
learning
18WM and Academic Skills
Age WM is Crucial for Indicators that WMNeeds Improvement
Pre-school Learning the alphabet Completing a puzzle independently Unwillingness to learn
Elementary School Understanding textual content (reading comprehension) Mental arithmetic Inability to understand what is read Problems memorizing the multiplication table
Middle School Completing homework independently Complex math problems, especially word problems Cant complete homework without parental supervision and direction Inability to grasp/break down word problems
High School Writing essays Difficulty writing neat, coherent essays
College Studying for an exam Participation in group projects Keeping focus/interest during a lecture Constantly procrastinates panics the night before the exam Doesnt listen or participate during a group project Difficulty remaining attentive during lectures

20Why is WM Important to School Psychologists?
- WM deficits identify LD more appropriately than
IQ - RTI calls for early
- Assessment of academic difficulties
- Identification of why child is struggling
- Implementation of targeted interventions
- Evidence-based interventions available for WM

Dehn, 2008
22Working Memory Academic Learning
- WM required whenever anything must be
learned,because learning requires - Manipulation of information
- Interaction with LTM
- Simultaneous storage and processing of
information - The capacity and effective functioning of WM
determines the extent of learning - WM capacity predicts performance on a wide
rangeof real-world cognitive tasks (Engle, 2002)
23Working Memory and Academic Learning
- WM has documented significant relationships with
- Reading decoding
- Reading comprehension
- Language comprehension
- Spelling
- Following directions
- Vocabulary development
- Note-taking
- Written expression
- Reasoning
- Complex learning
- Correlations range from
- .38 (Oral expression)
- -to-
- .59 (Math reasoning)
24Classroom Learning Demands on WM
- Common classroom activities that impose
simultaneous demands on storage and processing - Listening to a speaker while trying to take notes
- Following complex instructions
- Decoding unfamiliar words
- Writing sentences from memory
- Mental arithmetic
- Student must process new information and
integrate it with previously stored knowledge or
information that was just recently encountered - Learning is reduced or slowed when available WM
capacity is reduced through overloading of WM or
by requiring divided attention

Dehn, 2008
26Working Memory Learning Disability
- 2.9 million children (5.5 of school-age
population) have LD - Research has consistently found children with all
types of LD have poor WM performance (Swanson,
1990) - Especially in Verbal WM and Executive WM
- LD in Reading Impairments in Phonological STM
and Verbal WM - LD in Math Impairments in Visuospatial WM and
Executive WM
27Working Memory Learning Disability
- Executive WM serves a governing function
- Controls and regulates memory subsystems
- Executive-loaded WM tasks provide the best
discrimination between children with and without
LD - For example
- Students with LD have more difficulty with
reverse digit span tasks than their non-LD peers - Individuals with limited executive processing
often fail to spontaneously use rehearsal,
organization, and other executive dependent
strategies that allow effective and efficient use
of WM resources - WM span of students with LD is significantly
lower than non-LD peers - E.g., students with moderate LD could retain
verbal instructions that contained up to 3 units
of information, while non-LD peers can manage 5
units of information
28WM and Learning Disability
- Empirical evidence indicates that WM performance
is one source of data that can reliably
differentiate between students with a LD and
those who are slow learners(Swanson et al.,
1990) - Typically, another deficit in cognitive
processing constructs exists in addition to the
WM deficit - E.g., student with LD in Basic Reading Skills
might have coexisting deficits in phonological
processing and/or LTM - What sets those with LD apart is that WM tends to
be one of their intra-individual weaknesses - Best Practice Whenever a LD is suspected, WM
should be assessed as part of the comprehensive
evaluation
29Working Memory Reading
- Decades of research show a strong relationship
between WM and reading skills - Basic Reading Skills (Reading Decoding)
- Phonological STM and Verbal WM
- Phonological Processing and Visual Processing
- Reading Comprehension
- Verbal WM, Executive WM, and LTM
30Working Memory Reading Decoding
- Decoding involves
- WM
- STM
- Other cognitive processes (e.g., phonological
processing) - Retrieval from LTM (rapid automatic naming)
- Phonological processing forms the foundation of
reading decoding (Kamhi Pollock, 2005) - Requires
- Temporary storage of phonemes in phonological STM
- Simultaneous manipulation of those phonemes (WM)
- E.g., segmenting, blending
- Visual processing also important
- Visual stimuli must be processed and recoded
(grapheme-phoneme conversion)
31Working Memory Reading Comprehension
- Decoding individual words and accessing their
meanings - Assembling word meanings into larger meaning
units - Constructing representations of sentences
- Linking information across sentences
- Detecting inconsistencies between parts of the
text - Focusing attention on main idea
- Creating visual images
- Drawing plausible inferences on the basis of
prior knowledge - Monitoring the understanding of text as reading
progresses
32Verbal Working Memory Reading
- Necessary for successful reading comprehension
- Short-term memory for words and sentences
- Verbal WM facilitates reading comprehension by
holding words and sentences in consciousness
until there is enough information to complete an
idea - Holding process appears to be subvocalization
(inner speech in reading)
33Executive Working Memory Reading Comprehension
- Executive WM necessary for high-level processing
demands of reading comprehension - Coordinates many diverse processes that culminate
in integration of new information with an
existing mental model - Inhibition - Discarding no longer relevant
information and preventing entry of unnecessary
or irrelevant information - Affects ability to engage in processes that are
crucial to good comprehension - Inefficient inhibitory control during reading
overloads the WM system, causing comprehension
problems
34Working Memory Mathematics
- Strong relationship between WM and math
performance - WM and STM components utilized at varying degrees
depending on the task - Basic arithmetic calculation
- Mathematics problem solving
35Working Memory Math Calculation
- Simplest math calculation tasks require three WM
processes - Temporary storage to hold problem information
- Retrieval that accesses relevant procedures
- Processing operations that convert the
information into numerical output - Complex arithmetic calculation involves all WM
and STM components to varying degrees (Tronsky,
2005) - WM resources needed most during initial phases of
math skill acquisition - Fewer necessary as knowledge and skills build
- Processes become automatized (automatic)
36Working Memory Math Word Problems
- Strategy-based problem solving places a greater
load on WM than does calculation - When solving math word problems, individuals must
mentally construct an adequate problem
representation - This process that depends heavily on WM
- Initial stages of solving word problem involve
verbal comprehension and temporary storage of
words, phrases and sentences
37WM Requirementsfor Completion of Math Word
Problem
- Keeping track of incoming information
- Integrating information
- Retrieving math facts and procedures from LT
storage - Matching the correct algorithm to the problem at
hand - Updating the contents of WM
- Making on-line mathematical calculations
- Monitoring the computation process
- Evaluating the solution
- Dependence of problem solving on WM is especially
evident when the task is novel
(Swanson, 2006)
38Visuospatial WM and Mathematics
- Changes significantly during childhood
development - Visuospatial WM plays a prominent role during
preschool years - As young childs arithmetic mental model is
primarily visuospatial, rather than verbal and
abstract - By the end of first grade, verbal WM has become
the best predictor of arithmetic performance
39Working Memory Written Language
- Written expression is a complex activity that
requires integration of several cognitive
processes and memory components - Heavy emphasis on WM, especially
- Executive WM
- Verbal WM
- Visual WM
- Emphasis on phonological STM

57Can WM Be Improved?
58Remedial vs. Compensatory Interventions
- Remedial interventions
- Have the expressed goal of correcting a working
memory deficit by directly addressing the area of
weakness - Compensatory interventions
- Emphasize using the individuals cognitive or
memory strengths and assets in an effort to
bypass the deficit, thereby reducing its impact
on learning and performance - Strategy training
59Frequently Used WM Interventions
- Metacognitive training
- Extended to memory as metamemory training
- Rote and relational memory strategies
- Examples
- Rote Basic rehearsal strategies
- Relational Mnemonics, visual imagery
- Verbal WM interventions
- Elaborative rehearsal
- Semantic rehearsal
- Visuospatial WM interventions
- Recoding verbal information to visual information
- Executive WM interventions
- Dual visual-verbal encoding
- Organizational strategies
60Remedial vs. Compensatory Interventions
- All these interventions are primarily
compensatory in nature - But can we truly improve (remediate) WM?
- Cutting-edge research demonstrates that we can .
