Assimilation vs accommodation are core cognitive adaptation processes where assimilation adds new information to existing mental schemas while accommodation restructures those schemas entirely, both operating throughout life and forming the foundation for effective therapeutic interventions in cognitive behavioral therapy.
Ever learned something that completely changed how you see the world? Assimilation vs accommodation explains how our brains process new information—either adding to what we know or reshaping our entire perspective, and understanding these processes can transform your therapeutic journey.

Assimilation Vs Accommodation In Cognitive Development: Examining How We Adapt
Anyone who has taken a course on child development has probably heard the name Jean Piaget. Assimilation vs accommodation are two fundamental processes in Piaget’s cognitive development theory, where assimilation involves integrating new information into existing schemas, and accommodation refers to altering existing schemas or creating new ones in response to new information. Some may understand that he has something to do with a theory of cognitive development or childhood learning. Piaget also coined the term “adaptation” in the context of psychology. In this article, we are going to take a closer look at assimilation vs accommodation, two processes that fall under the umbrella of “adaptation”, or the concept of how we learn and process new information. We’ll also take a look at how these processes can continue to shape us as we learn throughout our lifetime.
Piaget and cognitive development
Let’s start with Piaget himself, and what he brought to the world in terms of understanding cognitive development. Jean Piaget was a Swiss psychologist who worked in the early to mid-twentieth century and achieved worldwide fame for his contribution to developmental psychology.
Unimpressed by the understanding of childhood learning at the time, Piaget revolutionized the ideas of education with his theory of stages of cognitive development. He examined how the brain processes new information throughout childhood up into adulthood and broke it into four stages: sensorimotor, preoperational, concrete operational, and formal operational stage. Piaget’s theory is used to this day in education and certain forms of therapy.
Schema in accommodation vs assimilation
To understand assimilation and accommodation and their role in adaptation, we do not need to understand the stages of development. Rather we need to look at one of the concepts within these stages called “schema”. The schema Piaget defined refer to units of knowledge that are used to respond to stimuli in an appropriate way, as well as organize information in the brain. Psychologists often refer to individual schemata (the singular form of schema), as “index cards” or “building blocks”.
Adaptation
Adaptation as a psychology term was coined by Piaget and refers to the manipulation of the schema, or learning and processing new information. The “index cards” of schema can be changed in a variety of ways: new information can be added to an existing card, the card may be moved to a new file, or information on the card can be erased entirely. New information changes our perceptions. This is learning, and it can be done throughout our lifetime.
What is assimilation?
Assimilation is the process by which new information is added to a concept we already know. This new information can be added as a note to the existing schema, but does not change the schema itself. So, for example, let’s take the concept of plants. You learn throughout your life about plants, and certain facts become a part of your concept of plants. Then let’s say you learn about carnivorous plants. You didn’t realize that there were plants that digested insects. It’s an expansion of your existing knowledge about plants, but doesn’t change your idea of other plants or plants in general.
What is accommodation?
Accommodation can be a more complex and gradual process than assimilation. Rather than simply adding information to a schema, accommodation involves changing it altogether. This is when you learn new information and then need to dismantle what you already know to better accommodate this information. An example of accommodation is when as a child, you learn the concept of “family” based on your own experiences. If your parents divorce, you may have to accommodate new, more complex ideas of what family looks like as the family unit changes.
Both accommodation and assimilation can occur naturally in a person’s life
Learning is a lifelong process. Both assimilation and accommodation continue to shape our lives as we move through adulthood. Cognitive structures may not often change in significant ways as we age, but recent research suggests that the brain continues to learn well into old age. We can still learn new information, form new memories, learn skills, and improve vocabulary and language.
Assimilation vs accommodation in adulthood’s cognitive development
Typically, new learning in adulthood falls under assimilation, as new info is added to existing ideas, or existing schemas. However, it is possible for accommodation to happen at any age. An example of this would be a person who for most of their life held to uninformed and bigoted ideas about a culture or cultures. Let’s say that this person then began working with a group of people from this culture and learned that their ideas were wrong, posing a challenge to their ethnocentric mental structures. Rethinking their position and opening up to other cultures is an example of accommodation.
Therapeutic applications in mental health
Both assimilation and accommodation can occur naturally in a person’s life, but sometimes they are actively sought. For example, someone who decides to participate in therapy may be looking to change the way they relate to themselves and their self-esteem. Cognitive behavioral therapy (or CBT) is an effective and popular form of talk therapy that is used to manage stress, learn how to learn new patterns of thought and behavior, and reduce symptoms of common mental health conditions such as anxiety or depression.
At ReachLink, our licensed clinical social workers utilize these principles of cognitive development to help clients navigate their mental health challenges. Through our telehealth platform, clients can engage in therapeutic processes that facilitate both assimilation and accommodation. For instance, a client struggling with anxiety might assimilate new coping strategies into their existing knowledge base, while someone working through trauma might need to accommodate entirely new perspectives on past experiences.
Our approach recognizes that meaningful cognitive change often requires both processes. When clients connect with one of our licensed clinical social workers through secure video sessions, they’re engaging in a structured environment specifically designed to facilitate these cognitive adaptations. The telehealth format allows clients to process new information in their own familiar environment, which can make the adaptation process more comfortable and effective.
The benefits of telehealth for cognitive adaptation
Research shows that participating in online therapy is just as effective as attending traditional, in-person therapy sessions. For many people, this is simply a more convenient way to get therapy, while others use it because they don’t have access to therapists that meet their needs where they live.
The telehealth approach that ReachLink offers provides unique advantages for the processes of assimilation and accommodation. Since clients can engage in therapy from familiar surroundings, they may find it easier to integrate new cognitive patterns into their daily lives. Our platform’s accessibility means that learning and adaptation can happen on a more consistent schedule, without the barriers of travel time or scheduling conflicts that might interrupt the cognitive development process.
It’s important to note that while our licensed clinical social workers provide expert therapeutic support, ReachLink does not offer prescription services. Our focus is exclusively on therapeutic counseling and behavioral interventions that facilitate cognitive adaptation through evidence-based approaches.
Takeaway
While Jean Piaget had revolutionary ideas about learning and child development, our understanding of these processes continues to grow today. Learning can change how we think for the better, no matter our age. If you are interested in changing negative thought patterns, increasing self-esteem, or managing stress in your life, therapeutic approaches that facilitate assimilation and accommodation can be effective ways to transform your cognitive frameworks and improve your mental wellbeing.
Through ReachLink’s comprehensive telehealth services, you can work with licensed clinical social workers who understand how to guide you through these cognitive processes, helping you adapt to life’s challenges with greater resilience and self-awareness.
FAQ
-
How do therapists use assimilation and accommodation concepts in therapy?
Therapists apply these concepts to help clients understand how they process new experiences. In cognitive behavioral therapy (CBT), therapists work with clients to identify when they're forcing new information into old patterns (assimilation) versus when they need to update their thinking (accommodation). This awareness helps clients develop more flexible coping strategies and healthier thought patterns.
-
Can therapy help when someone struggles with adapting to change?
Yes, therapy can be very effective for adaptation difficulties. Dialectical behavior therapy (DBT) teaches distress tolerance and emotional regulation skills, while CBT helps identify and challenge rigid thinking patterns that make change difficult. Talk therapy provides a safe space to explore fears about change and develop personalized strategies for managing life transitions.
-
What therapeutic approaches address rigid thinking patterns?
Several evidence-based approaches target cognitive inflexibility. CBT helps identify and restructure rigid thought patterns, while acceptance and commitment therapy (ACT) focuses on psychological flexibility. Mindfulness-based therapies teach present-moment awareness that can break automatic thinking cycles. Family therapy can address rigid family systems that resist healthy change.
-
How does understanding assimilation and accommodation help in family therapy?
In family therapy, these concepts help identify how family members process information about each other and their relationships. Families often get stuck in assimilation patterns, interpreting new behaviors through old assumptions. Therapists help families practice accommodation by encouraging openness to new ways of understanding and relating to each other, fostering healthier family dynamics.
-
When should someone seek therapy for adaptation difficulties?
Consider therapy if you consistently struggle with life changes, feel stuck in repetitive patterns, or experience significant distress when facing new situations. Signs include persistent anxiety about change, difficulty learning from experiences, or relationship problems due to inflexible thinking. ReachLink's licensed therapists can provide personalized support through telehealth sessions to help you develop healthier adaptation strategies.
