3. Cognitive Remediation
“is a behavioral training based intervention that aims to
improve cognitive processes
(attention, memory, executive function, social
cognition, or metacognition) with the goal of durability
and generalization.
…where social cognition is defined as “the mental
operations that underlie social interactions, including
perceiving, interpreting, and generating responses to the
intentions, dispositions, and behaviors of others.”
Cognitive Remediation Experts Workshop 2010

4. Cognitive Remediation
Is a Learning Activity
• Learning relies on neuroplasticity
Neurons in the brain adjust their activity
and organization in response to new situations
or to changes in the environment
• Schizophrenia and neuroplasticity
Patients receiving CR demonstrated a decelerated
loss of and, in some cases,
increase in gray matter volume

6. Examples of Computer based
Cognitive Exercises

7. Cognitive Remediation and
Computers
• Many different software companies make exercises to
improve cognition
• There have been no head-to-head studies comparing
software within and between companies
• Some CR programs use one software
and others use a combination of software
• Engaging software has better outcomes

13. Promote Intrinsic Motivation
• Use engaging activities
• Contextualize
• Personalize
• Offer Learner Control

14. Personalizing Treatment
• Link cognitive remediation to personally relevant
goals
• Different training exercises for different people
• Find the sweet spot of challenge
• Combine with therapies that are relevant to
recovery goals

15. Cognitive Remediation Programs
Typical Components Where They Are Found
• Assessment of • Outpatient clinics that offer
baseline cognition psychosocial rehabilitation
programming
• Set cognitive goals as they relate
to recovery goals • Long-term residential/
inpatient care settings
• Groups 2+/week;
3-4 months; drill practice strategy
• Include bridging activities
• Track progress
