Cognitive Development: Helping Staff Members Understand Child Development

Every child develops at a different rate, but children and youth usually follow predictable patterns in how they grow and learn. Your role is to ensure staff members recognize and use their knowledge of child development. This lesson will review typical cognitive development from birth to age 12. You will learn about developmental milestones and how to ensure staff members understand cognitive development.

Objectives
  • Describe the cognitive developmental milestones for children and youth in a way that supports staff members’ knowledge of child development.
  • Describe expected variations in cognitive development across childhood.
  • Identify ways to support staff when they have concerns about a child’s development.

Learn

Teach

Think back to your own childhood, your time raising young children as a parent or caregiver, or your time working with infants, toddlers, preschoolers, or school-age youth. What celebrations do you remember? What did you find most exciting or rewarding? Perhaps your answer is watching a child’s everyday accomplishments: first steps, first words, writing a name, reading a sentence, riding a bicycle, or making a friend. These memorable events; often called developmental milestones, are exciting. Developmental milestones are things most children begin to do within a certain age range. Developmental milestones are a guide. They help you understand and celebrate children’s development, but they also must be considered carefully. Each child develops at their own pace, and many of the behaviors that experts consider milestones are influenced by cultural expectations. For example, an infant who is born into a culture that prefers to keep babies off the floor for hygiene reasons will develop motor skills in a different pattern from a child who is born into a culture that prefers frequent "tummy time.” The goal is not for every child to develop the same way or at the same pace. Rather, the goal is for you to help staff develop curiosity about each child’s development, help them understand the patterns that they see across time and children, and help them recognize when there is a potential concern. Then staff use this knowledge to plan learning environments and experiences that meet each child’s needs.

Understanding Cognitive Development

This lesson provides a brief overview of how cognition (thinking skills) develops from birth through age 12. Staff members have received similar information in their own courses, so you can help staff members understand these milestones. Emphasize that each child is unique. Milestones are not rigid rules about when to expect certain skills or behaviors. Development is also holistic: cognitive development is influenced by language, physical, and social development. As highlighted in the Communication and Physical courses, milestones provide a guide for when to expect certain skills or behaviors to emerge.

Discussing developmental milestones with staff also provides an opportunity to challenge ableism. Ableism is a form of discrimination that favors non-disabled people. For example, an infant who is born blind will not meet the milestones in the chart below exactly as they are written, but that does not mean the child has cognitive delays. Instead, staff members must find meaningful and accessible ways for the child to explore with all their senses. It is also important to remember that developmental milestones should never be forced. An autistic child, for example, may not feel comfortable looking at faces or engaging in make-believe play, so staff should not expect every child to show every developmental milestone. When you talk with staff members about developmental milestones, remember to focus on what children can do, their strengths, and how they show what they know. For new staff who have relatively little experience with children, milestones can help them develop realistic expectations for children’s behavior. For example, if a staff member knows that a toddler typically can only follow a one-step direction (e.g., “Sit down”), they can adjust the way they provide directions. Milestones are helpful for considering where a child is and what experiences may help them continue growing.

Cognitive Development from Birth to Age 5

Infants’ and toddlers’ thinking skills grow as they interact with the world and people around them. As you learned in the first lesson, early experiences matter. Consistent, nurturing experiences help infants and toddlers make sense of the world. Those experiences literally build brain architecture. As infants and toddlers develop, they begin to understand and predict how things work: they open and close a cabinet door over and over, they fill and dump a cup of water in the water table, they bang a spoon on a highchair to hear the sound.

Because development is so rapid during the first three years of life, it is helpful to consider developmental milestones across the infant and toddler years. You will help staff members understand these milestones. Direct care staff received a chart about infant and toddler development in their own lessons. It’s important that you help them remember individual differences exist when it comes to the specific age at which infants and toddlers achieve milestones. As highlighted in the Communication & Language Development and Physical Development courses, milestones provide a guide for when to expect certain skills or behaviors to emerge. The table below is a comprehensive list of cognitive developmental milestones for infants and toddlers. A brief version of the information aimed at parents can also be found in an easy-to-use checklist from the Centers for Disease Control and Prevention:

During preschool, amazing changes happen in children’s “thinking skills.” Their memories are becoming stronger—they often remember surprising details. They can share their ideas in new and interesting ways. Their imaginations are becoming a primary vehicle for play and learning. They begin to compare, contrast, organize, analyze, and come up with more and more complex ways to solve problems. Math and scientific thinking become more sophisticated.

Cognitive development is a unique process specific to each child, youth, and family. Many factors influence cognitive development, including genes, events during pregnancy or birth, and aspects of the child’s environment. A family may wonder about their young child’s cognitive development and feel uncertain about what they are observing and what to expect. As a trainer or coach, work with staff members to first learn from a family, and then to consider offering additional developmental information, including possible warning signs. The Kids Included Together website, https://www.kit.org, can be a valuable resource for you, as can the developmental milestones and Act Early information located on the Centers for Disease Control and Prevention website, https://www.cdc.gov/ncbddd/actearly/index.html.

Staff members may come to you first when they have concerns about an infant or toddler’s development. You should be prepared to discuss common concerns with staff members, support their engagement with families, and help them understand your program’s support systems or referral processes for additional services. The tables below highlight some possible warning signs that may be noticed during regular observations or developmental screening. If you or a staff member notice these concerns, you can share information with families about typical child development and let them know you are available to talk.

Possible Warning Signs for Infants and Toddlers

Young Infants

  • Does not watch things as they move
  • Does not bring things to mouth

Mobile Infants

  • Does not try to get things that are in reach
  • Has difficulty getting things to mouth
  • Does not play any games involving back-and-forth play (e.g., peek-a-boo)
  • Does not seem to recognize familiar people
  • Does not look where you point
  • Does not transfer toys from one hand to another
  • Does not learn gestures like waving or shaking head
  • Loses skills they once had
  • Does not search for things they see you hide

Toddlers

  • Does not copy others
  • Does not point to show things to others
  • Does not know what to do with common things, like a brush, phone, spoon
  • Does not follow simple directions
  • Does not play pretend or make-believe (at 3 years)
  • Loses skills they once had

Possible Warning Signs for Preschool Children

3 Years

  • Cannot work simple toys (such as peg boards, simple puzzles, turning a handle)
  • Does not play pretend or make-believe
  • Does not understand simple instructions

4 Years

  • Has trouble scribbling
  • Shows no interest in interactive games or make-believe
  • Does not follow follow three-part commands
  • Does not understand the concepts of "same" and "different"

5 Years

  • Does not respond to people, or responds only superficially
  • Can not tell what is real and what is make-believe
  • Does not play a variety of games and activities
  • Cannot give first and last name
  • Does not draw pictures

 

Ultimately, if families are concerned about their child’s development, they should talk to their child’s pediatrician about their concerns. Pediatricians can perform developmental screenings and possibly refer the child to specialists. Families should also contact their statewide early intervention program (for children under age 3). These programs will provide a free evaluation of the child’s development. This can help the child get the services and help he or she needs. This video, developed by the U.S. Centers for Disease Control and Prevention, offers tips for identifying and acting on suspected developmental delays: https://www.cdc.gov/NCBDDD/actearly/multimedia/video.html

Cognitive Development During School-Age Years

School-age children’s thinking skills become increasingly sophisticated as they encounter new people, places, and ideas. They develop the ability to learn in abstract ways from books, art, movies, and experiences. They are able to focus and concentrate on tasks for longer periods of time, understand a variety of concepts and their memory improves significantly. You have the exciting opportunity to witness some children’s first encounters with formal schooling and to watch others learn as they move between grades and schools. The chart below highlights cognitive development milestones during the school-age years.

Cognitive Developmental Milestones

Middle childhood (ages 5-7)

  • They begin to see things from other school-age children’s perspectives and begin to understand how their behavior affects others
  • They enjoy planning and building
  • They understand concepts of space, time, and dimension. They understand concepts like yesterday, today, and tomorrow
  • They know left and right
  • They begin to develop a sense of self-confidence and mastery of their learning
  • They begin to reason and argue
  • They can perform simple addition and subtraction

Early adolescence (ages 8-12)

  • Most early adolescents are fully capable of perspective taking and understand and consider other’s perspectives
  • They begin to think hypothetically, considering a number of possibilities, and are able to think logically
  • They become more goal oriented
  • They may develop special interests that are a source of motivation
  • Cognitive development may be impacted by their emotional state
  • They begin to understand facets of the adult world like money and telling time
  • They appreciate humor and word games

Cognitive development is a unique process and is specific to each school-age child. Sometimes school-age children may exhibit cognitive difficulties that can affect their learning and behavior. Some potential red flags for school-age cognitive development include:

  • Lacking an understanding of basic concepts such as colors, shapes, letters and numbers
  • Intense frustration by school-related tasks and assignments
  • Inability to follow the rules of games or assignments
  • Inability to stay focused and on-task

School-age children experiencing difficulties may not receive proper interventions, supports, or care from caregivers and other adults. We might ignore some behaviors because we think that they are related to mood changes that most middle and early adolescent school-age children experience. However, certain behaviors should not be overlooked. These include (Center for Disease and Control and Prevention, 2021):

  • Excessive depression
  • Antisocial behaviors, or the inability to relate to peers or fit into a peer group
  • Acting out
  • Difficulty staying engaged in an academic task

It is important to help staff recognize the difference between behaviors that might be frustrating to adults (e.g., listening to loud music, talking back, occasional moody behavior) and behaviors that are truly hurtful (e.g., excessive depression, antisocial acts, harmful risk-taking behavior). If you or staff are concerned about a school-age child's development, those feelings should not be ignored. Gather information and observations, brainstorm with staff, and work together to talk with families about your observations. Ultimately, families may choose to discuss concerns with a pediatrician or their local school district. This may result in additional supports for the child. Regardless of the families’ choices, remember that your role is to help staff create a successful learning community for each and every child.

Helping Staff Members Promote Cognitive Development

Staff members must use their knowledge of child development to work appropriately with the children in their care. Be prepared to teach staff effective strategies for facilitating cognitive development. When working with staff members in the classroom, observe as they engage with children to ensure they do the following:

Infants and Toddlers

  • Give infants and toddlers the safe space they need for movement and discovery (areas for climbing, crawling, pulling up, etc.).
  • Provide a consistent, nurturing relationship with each infant and toddler.
  • Recognize that children need different things as they move through the developmental stages.
  • Observe children on a regular basis to determine where they are developmentally so staff can both support and challenge their emerging skills.
  • Remember that children are unique and progress at different rates and that one area of development may take longer than other areas.

Preschool

  • Provide interesting materials that spark preschoolers’ interests and allow for hands-on exploration.
  • Provide a range of developmentally appropriate and culturally diverse books.
  • Find teachable moments to encourage learning and development.
  • Observe children on a regular basis to determine where they are developmentally so staff can both support and challenge their emerging skills.
  • Remember that children are unique and progress at different rates and that one area of development may take longer than other areas.

School-Age

  • Provide thought-provoking materials and challenging games for school-age children to complete if or when they have some downtime.
  • Provide a variety of developmentally appropriate and culturally diverse books for school-age children to read.
  • Model the values of caring, respect, honesty, and responsibility.
  • Make sure that the space is culturally responsive and that there are positive portrayals of different genders, races, ethnicities, and disabilities. 
  • Ensure the space is accessible to all children and reflects the needs and interests of the school-age children.
  • Provide spaces where school-age children can cool down or de-stress.
  • Allow the school-age children to design or personalize part of the space.
  • Implement activities where children and youth can use their strengths and abilities.

There are some common struggles shared by many new staff members as they learn to understand cognitive development. Sometimes staff struggle with collecting and interpreting information about children's development. They may not understand how to make the connection between a child’s development and the experiences your program offers. Watch this video to learn from experienced Training and Curriculum Specialists about other challenges you might be prepared to support.

Helping Staff Understand Cognitive Development: Common Issues and Concerns

Listen as these T&CSs describe the biggest challenges staff face.

What can you do when staff members encounter these problems? As an instructional leader, you can help staff members understand how to make the most of the information they collect about children's development. Data is meaningless unless it is put to use! Staff might need your support identifying how their observation notes match up with developmental milestone checklists, learning standards, or curriculum objectives. They might need support learning how to plan experiences around caregiving routines for infants and toddlers, or they might need support knowing how to use what they know about child development to plan for the wide variability of ages in school-age programs. You can help staff members identify where children are and what goals are appropriate for them. While plans for different age groups will vary, they share some similarities. All quality plans, regardless of the age of the children, consider the interests of the children, the abilities of the children, and the experiences of the children. Teach staff how your program collects information about children's interests, abilities, and experiences. Make sure staff members know how to follow your program's observation and assessment procedures. Then teach staff members how to analyze the information they collect. What does their data tell them about individual children, groups of children, or the whole class or program?

Meeting the Cognitive Development Needs of All Learners

Teach staff members about your program’s commitment to serving all children and youth. In their own courses, staff members have learned strategies for meeting the needs of individual learners. Staff members will need your support to know how and when to use the strategies they have learned. Teach staff members to recognize the range of abilities in their classrooms or programs. It is critical to understand the needs of children with individualized education programs (IEPs), but it is equally important to understand that all children and youth need individualization. Help them consider and plan for the preschooler who needs an extra challenge, the toddler who is learning more than one language, or the pre-teen who sits quietly by herself.

Model

You help set the expectations for developmentally appropriate practice in your program. You can use the following strategies to help staff members understand the development of children and youth with a range of needs and abilities:

  • Have a strengths-based approach. Begin conversations by discussing what the child, youth, or family brings to the program and what they can do.
  • Focus on outcomes. Discuss with staff members the development and learning goals that are appropriate for each individual child. Then help plan experiences to meet those goals.
  • Advocate for maximum participation. Recognize when a child is capable of more than is being offered. Make sure all children have the opportunity to challenge themselves and participate to the maximum extent possible.
  • Interact. Talk to every child. Communicate that every child has a place in your program. Jump in and help when needed.
  • Arrange for the staff member to observe others who have strong or creative methods for observing and documenting children's development.
  • Model observation and note taking, then discuss how and why you recorded what you did about a child's development.
  • Help identify other sources of information that can contribute to understanding the child's development.

Observe

Observe in classrooms or programs. Make special notes about children you see struggling. Also be sure to note children who seem to need an additional challenge. Look for signs that staff members understand child development and have realistically high expectations for children's development. Take a look at the following scenarios and think about what you would see, say, and do in each.

See Say Do

 

Scenario

What you see:

Joshua, age 10, is in constant motion. He paces from area to area in his school-age program. He does not try any activities. He does not talk to any peers. He just walks from space to space. Staff members have come to you with concerns about his development.

You Say

What staff might say to support thinking skills:

“I understand your concerns, and I’ve noticed some of the same things. I’d like to think with you about ways we can learn more about Joshua and his interests. What have you noticed that has captured his interest—even for a short time? Are there any other youth he seems to like being around? When he talks to you, what does he like to talk about?”

You Do

What staff might do to support thinking skills:

Observe with the staff members. Observe Joshua and several peers, so you can get a sense of (a) how Joshua interacts with materials and people and (b) how other youth of the same age tend to use the space. Have a conversation with the staff members about their notes and your own. Discuss ways Josh is thriving in the program and ways he could be supported. If concerns persist, follow your program’s policies for addressing concerns about development.

Scenario

What you see:

Britta, age 4, has cerebral palsy. She uses a wheelchair and has limited control of her hands and arms. She does not like the sensory experiences in her preschool classroom. She will not put her hands or fingers into water, sand, paint, or any other substance. She hates play dough. Last week when the class planted flowers, Britta cried and refused to participate. The staff members in Britta’s room tell you they are worried that Britta is missing out on important experiences with the other children. They are having a hard time understanding what she knows and where she is developmentally.

You Say

What staff might say to support thinking skills:

“You’ve noticed an important thing: every child shows you what they know in different ways. I’m wondering what Britta might be able to show if we look in different ways. It sounds like she doesn’t like some of the typical hands-on activities. Let’s brainstorm together some different ways she can show how much she knows and can do.”

You Do

What staff might do to support thinking skills:

Share resources about Universal Design for Learning (http://www.udlcenter.org/) to identify different ways Britta can express herself. Help make sure staff members are familiar with Britta’s IEP and the types of supports Britta needs for learning. Share observations you make about Britta’s development across domains—being sure to emphasize ways Britta’s cognitive development is age-appropriate.

Scenario

What you see:

Celina, age 17 months, is extremely affectionate. She hugs children and is reluctant to let go. Often, the other children start to scream, cry, and push away. A few times she has wrestled children to the ground while giving hugs. The staff members in Celina’s room have requested your help and would like to talk to her family about their concerns.

You Say

What staff might say to support thinking skills:

“I’m glad you are paying such careful attention to Celina’s development and thinking about ways to involve families. Let’s take a moment to review your notes and observations about Celina’s development. Toddlers sometimes have a hard time using words, so they use their bodies instead. Before we talk to Celina’s family, let’s make sure we understand as a team what Celina is trying to communicate. Then we can talk with her family about what they’ve noticed, as well, and what works at home.”

You Do

What staff might do to support thinking skills:

Review staff members’ assessment and observations of Celina. Observe in the classroom to help identify situations or peers that seem to be associated with the most hugging. Help staff members understand how toddler cognitive, communication, and social development are connected.

You play an important role in promoting the cognitive development of all children, including those with disabilities. You can support staff as they learn about child development. Understanding child development helps them plan and implement programs that support all children and youth.

Explore

Much of what we know about child development comes from theory and research, but it has important implications for your work every day. Take some time to think about how knowledge of cognitive development gets put into practice in your program. Complete the Turning Theory Into Practice activity which applies theory and research about child development to everyday practices that support cognitive development.

Apply

You may be part of conversations with staff members about child development. Use the Discussing Cognitive Development guide to have conversations with staff members about child development. You can also use the guide to prepare for meetings with families about their child’s cognitive development.
