1.6 Cognitive Development: Overview

Cognitive Development

A Brief Overview1

In the Typical Cognitive Development section of this course, we described how cognitive development involves the development of thinking or evaluation and coping, or ‘adaptation’ skills. Thinking or evaluation skills, such as “thinking outside the box2 (see full Glossary),” are related to the development of intelligence (see full Glossary). Coping skills involve the ability to adapt to changes in one’s environment.  Cognitive skills also look at creativity, the ability to learn new things, retain (see full Glossary) what one has learned, and how one applies information to new situations. Cognitive development also includes pre-academic and academic skills that children need in order to succeed at school. Examples might include the ability to sit quietly for certain periods of time, the ability to listen and follow instructions and the ability to perform paper and pencil tasks.

Some children do not develop these skills at par with their peers. They may develop some of these skills much later than others —or not develop them at all. In other words, atypical cognitive development involves difficulties with both the quality and quantity of certain skills (see full Glossary):

Severe cognitive delays often effect all other areas of development. Below are some signs of cognitive delays that can be observed in all areas of development between the preschool and school age years, around ages 3 – 5 years old.

In the domain of cognitive development:

  1. Children may experience serious difficulties in learning basic concepts (e.g. colors and shapes);
  2. Children may experience serious difficulties in learning advanced concepts (e.g. counting, reading and writing);
  3. Children may experience serious difficulties in generalizing what they learn from one situation to the next;
  4. Children may experience serious difficulties in adapting to changes in their environment and to new situations.

In the domain of social/emotional development:

  1. Children may trust others too easily and readily enabling others to take advantage of them;
  2. Children may not read visual or language cues as they their attempt to socialize with others.

In the domain of motor development:

  1. Children may exhibit delays in the development of their fine motor skills;
  2. Children may exhibit delays in the development of their gross motor skills

In the domain of communication development:

  1. Children may exhibit delays in the development of their receptive language skills;
  2. Children may exhibit delays in the development of their expressive language skills;
  3. Children may exhibit delays in the development of their pragmatic skills;
  4. Children may exhibit delays in the development of their articulation skills.

In the domain of adaptive skills:

During the preschool years:

  1. Children may be delayed in becoming toilet trained, and in extreme cases, may never be toilet trained.

During the elementary school years:

  1. Children may experience difficulties bathing and cleaning themselves properly;
  2. Children may experience difficulties with dressing and undressing.

During the high school years:

  1. Male adolescents may experience difficulties with knowing how and when to shave;
  2. Female adolescents may experience difficulties knowing how to handle their menstrual cycle.

Severe cognitive delays have been linked to developmental disabilities (also known as mental retardation and developmental challenges). Developmental disabilities involve global delays and affect all areas of development, including motor, language, social and emotional, and self-help skills.

1.6 Cognitive Development: Pre-Academic/Academic Skills

Pre-Academic/Academic Skills

It is very important to recognize and address the signs of delays in the pre-academic and academic (see full Glossary) areas in young children. Being aware of milestones (see full Glossary) and addressing any difficulties during the early years is likely to make a difference in the child’s learning and progress during his school years, and as he or she grows older. A child with these delays who does not receive help may be at risk when functioning within the school setting and in his/her daily activities.

Between 3 and 5 years old Some signs of pre-academic/academic delays may include the following examples.

If a young child:

  • Does not group or separate toys or other objects, or put them into  categories (see full Glossary); for example, ‘blueberries go in one plate and strawberries go in a different plate;’ (Fig. 1)

categories

  •  Does not match (see full Glossary) pegs, toys or other objects of the same colour (for young preschool children); of the same colour and shape (for older preschool children); of the same colour, shape and size (for children in Kindergarten and older);
  • Does not sort (for example: cannot tell which item goes with which: spoon goes with fork, shorts go with jacket);
  • Does not recognize a pattern and continue it (for example: red blue, red blue…); this is a very important concept in the development of mathematical skills;
  • Does not answer “why” questions (for example: Why do we eat? Why do we sleep?);
  • Does not understand “cause and effect” relations (for example: the reason we can’t play with this toy is because you broke it.);
  • Does not retell basic parts of a story;
  • Does not describe what he or she is doing;
  • Does not think about future events;
  • Does not predict “what will happen next”, (for example: Mom forgot to turn off the water. What do you think will happen?);
  • Does not count (Fig. 2: Counting toes);

By age 6 years:

  • Does not tell “which one has more” (for example: a plate with three strawberries and a plate with five strawberries);
  • Does not perform simple addition activities (for example: If you have two pennies and I give you one more, how many will you have?);
  • Does not perform simple subtraction activities (for example: If you have three crayons and I take away one, how many will you have left?);
  • Does not recognize letters of the alphabet;
  • Does not recognize own name in print;
  • Does not read simple words;
  • Does not copy letters (from memory or an example);
  • Does not copy simple words (from memory or an example);
  • Does not copy own name (from memory or an example).
