Is there a difference between auditory comprehension and reading comprehension?
What They Have in Common
• Both involve language • Both depend on:
– Emotional involvement – Executive functioning skills– Attention – Working memory – Long-term memory – They share many brain mechanisms
Some Major Differences
Auditory Comprehension
• Involves auditory channels
• Not directly taught• Less demanding
Reading Comprehension
• Involves visual or tactile channels
• Must be taught• Can be negatively
Influenced by fluency level
Overview of Language Anatomy
• Language Implementation System
• Conceptual System• Mediational System
Kandel et al, 2000
Language Implementation System
Analyzes auditory signals in order to activate conceptual knowledge
Ensures phonemic and grammatical construction and articulatory control
Conceptual System
• A collection of regions throughout the remainder higher-order association cortices
• Supports conceptual knowledge
Neurocognitive
Requirements
for Information Processing
Neurocognitive Requirements for Comprehension
• Emotional involvement • Executive Functions• Attention skills• Working Memory• Long-term memory skills
Why Emotions Are Important for Learning
• Emotional system:• primary function is self preservation
– Guides our judgment & actions – Enables us to construct goals– Enable us to transfer school learning to
real-life decision making – We use past emotional knowledge to guide
our reasoning process• Social regulation • Moral reasoning
(Immordino-Yang & Damasio, 2007)
Why Emotions Are Important for Learning
• While making decisions we analyze events in their emotional context.
• We consider our past experiences– Rewards & punishments– Successes and failures– Praise and disapproval
Attention
• Is a state of being, not an anatomical entity
• Has many components of attention
• Works in coordination with EF & WM
• Neurobiological research views motivation as the engine that activates and maintains attention
Working Memory
• Each of the 5 primary senses has a working memory that serves it
• Visual Working Memory sustains:– Images and shapes of objects– Dimensions & spatial properties – 1-2 seconds
Working Memory
• Verbal Working Memory• For verbal and written
information• Major components:
– Phonological loop– Phonemic buffer
• 0.5 to 3 seconds• Enables us to forget and encode
Interaction Between Attention & W. Memory
• During acquisition of new skills• Role of attention resource allocation
system• What happens when reading fluency
is decreased?• Analysis & synthesis are a product of
the interaction between attention & WM
Executive Functions
• A number of “complex cognitive processes that serve ongoing, goal-directed behaviors” (Meltzer 2007)
• Include:– Goal setting & planning – Flexibility – Self-regulatory functions
Executive Functions
• Self-regulation – Organization of behavior:
• Initiating, sustaining, shifting, inhibiting
– Self-monitoring – Managing time resources – Backtracking – Identifying errors– Monitoring progress towards goal– Shifting mindset
Mechanics of Auditory Processing
• From sound waves to neural energy
• Analysis of frequency & loudness
• On the level of the auditory nerve & auditory pathways
Mechanics of Auditory Processing
• In the temporal cortex:–Sounds identified & paired with
neural representations–Sounds are assembled into words–Words are paired with their
meanings–Meaningful word sent to frontal
lobe centers
Mechanics of Auditory Processing
• In the frontal lobe:–Broca’s area verifies meaning &
grammatical properties–Numerous decisions are made
about word categories, semantic connotations, etc
–The processed word is sent back to temporal cortex
Reading Comprehension
“Reading is an interaction among the reader, the situation, the task, and the text that results in the construction of meaning”
(Meltzer 2007, 194)
Reading Comprehension
• To comprehend meaning of the text, the reader relies on EFs to monitor and take charge of the construction of meaning
(Meltzer 2007)
Role of EFs in Reading Comprehension
• The good reader is engaged in: –Active, conscious effort –Thinking & problem-solving–Ongoing expansion and refinement
of vocabulary –Progress monitoring
(Kintsch 2004; Joyce, Weil & Calhoun, 2004)
•
Role of Executive Control in Reading Comprehension
• The good reader starts with a comprehension goal & a plan for monitoring progress toward that goal–Prioritizing is part of the plan
Role of Executive Control in Reading Comprehension
• The good reader…..• Identifies and coordinates
strategies • Organizes incoming information• Monitoring progress toward goal• Can demonstrate understanding
of the text
Executive Control of Reading Comprehension
• Gaskins, Satlow & Pressley (2007) have identified 7 EC principles that govern the relationship between EFs & reading comprehension.
(in Meltzer 2007, 194-215)
The 7 Executive Control Principles
• Reading must make sense• Understanding results from
planning to understand– Survey, predict, set purpose
• Prioritizing maximizes time & effort
The 7 Executive Control Principles
• Accessing background information helps organize new information
• Ongoing self-checking enhances goal achievement
The 7 Executive Control Principles
• Cognitive flexibility provides opportunities for increased understanding
• Ongoing self-assessment improves understanding
(Meltzer 2007, 194-215)
Maximizing Emotional Involvement
• Establish a friendly atmosphere in class– Negative affect narrows creativity (D. Rose)
• Clearly highlight value of the info to life experiences
• Understand the learner– Background knowledge & thinking– Take learner variability in perspective– Judge a person by the questions s/he asks
Maximizing Emotional Involvement
• Ask questions–Questions you ask enables student to hone on the target information
–Sharpen focus on the learning goals
Maximizing Emotional Involvement
• Emphasize salient goals and objectives
• Frequently remind student of goals• Collaboration & group work • Vary response methods
– Will engage multiple networks
• Monitor motivation
Facilitate Integration by:
• Putting new information in its context
• Activating background knowledge &
•Emphasizing connections among things
Placing Things in Context
• The brain is always trying to predict things in the environment– Looks for patterns– Encodes & recalls info. in context– When we recall events we recall our
experiences with them– There is a special network that allows us to
focus on specific things within their context
• A major goal of educators should be: highlighting the patterns of things
Placing Things in Context
• Role play & acting • Enable people live the
experience• Provide a meaningful
context
The Reading Material
• Value of realistic stories/examples from life:–Induce physical feelings in us–Elevate our emotional response to learning
–Enable us to live the experience–Increase our motivation
Role of Sleep
• Required for all types of cognitive functions
• Necessary for emotional intelligence • Improves mood & empathy• Elevates internal motivation • Improves attention •
Sleep & Emotional Regulation
Mood: • Sleep plays a major role in emotional
regulation (Walker 2009; Walker & Van Der Helm, 2009)
• Sleep leads to:– More efficient rationalization and
resolution of interpersonal conflicts, moral reasoning, decision making, emotional expression, and processing of emotional faces.
(Pace-Schott et al 2011)
Sleep Improves:
-self-regard -assertiveness-independence-self-actualization
Conclusions
• The material for auditory and reading comprehension is language
• For the most part the two types of processing utilize the same mechanisms
• Both types of processing can be effectively enhanced through improving executive functions
Conclusions
• The role of emotions in learning is just beginning to be understood
• Sleep regulation is crucial for information processing and all types of neurocognitive functions
• Physical exercises improve WM & attention, which will significantly improve information processing
