When do babies start talking?

Langauge Development

Children’s langauage development progresses at very different rates in all individuals. Below is a rough guide of what to expect in your child’s langauge development from age 0 to 5 years old. Babies start ‘talking’, or using words, around 9-12 months old.

  • Zero to 1 years old
  • 1 to 5 year olds
  • Birth – 3 months:

    From the very start, infants pay close attention to language. In the first year, they can distinguish all of the speech sounds that occur in natural language; then they begin to specialize in the sounds of their home language. Most infants will:

    • Respond to speech by looking at the speaker
    • Respond differently to the voice of a parent than to other voices
    • React to changes in a speaker’s tone, pitch, volume, and intonation
    • Respond differently to their home language and another language
    • Communicate with bodily movements, by crying, babbling, and laughing
    • Attempt to imitate sounds

    3 – 6 months:

    Even small babies love to have “conversations.” Most children of this age:

    • Exchange sounds, facial expressions, or gestures with a parent or caregiver
    • Listen to conversations
    • Repeat some vowel and consonant sounds

    6-9 months:

    Children’s vocalizations increase. Most babies of this age:

    • Begin repetitive babbling (deaf children also start to babble with their hands)
    • Associate gestures with simple words and two-word phrases, like “hi” and “bye-bye”
    • Use vocal and non-vocal communication to express interest and influence others

    9-12  months:

    Children are getting ready to talk. Around the first birthday, language production doubles. Many babies of this age:

    • Understand the names of familiar people and objects
    • Show their understanding with responsive body language and facial expressions
    • Say a few words
    • Respond to a firm “no” by stopping what they are doing

    Langauge development 1-5 years

    1 – 2 years:

    Children begin to learn many new words and begin to use simple phrases. Many children can:

    • Understand many words, as well as simple phrases and directions (“Drink your juice”)
    • Follow a series of two simple but related directions
    • Respond correctly when asked “where?”
    • Say a few words clearly, and a few dozen additional words so that family members can understand. The words denote important people and common objects, and a few prepositions such as “on,” “in,” or “under.” Many can say “more” and “all gone.”
    • Say successive single words to describe an event
    • From about 18 months, begin learning about 9 new words a day
    • Use “my” or “mine” to indicate possession; begin to use “me,” “I,” and “you”

    2-3 years:

    Both understanding of language and speaking develop more rapidly at this stage. Most 2-year-olds can:

    • Join familiar words into phrases
    • Begin to use modifiers (adverbs and adjectives)
    • Point to common objects when they are named
    • Name objects based on their description
    • Respond to “what?” and “where?” questions
    • Enjoy listening to stories and asking for favorite stories
    • Recount events that happened that day

    3-4 years:

    Language usage becomes more complex. Most 3-year-olds can:

    • Make themselves understood to strangers, despite some sound errors
    • Use and understand sentences
    • Use more complex grammar, such as plurals and past tense
    • Understand sentences involving time concepts (for example, “Grandma is coming tomorrow”) and narrate past experiences
    • Understand size comparisons such as big and bigger
    • Understand relationships expressed by “if… then” or “because” sentences
    • Follow a series of two to four related directions
    • Sing a song and repeat at least one nursery rhyme

    4-5 years

    4-year-olds use language not only to converse, but also to exchange information. Most can:

    • Retell a story (but may confuse facts)
    • Combine thoughts into one sentence
    • Ask “when?” “how?” and “why?” questions
    • Use words like “can,” “will,” “shall,” “should,” and “might”
    • Combine thoughts into one sentence
    • Refer to causality by using “because” and “so”
    • Follow three unrelated commands appropriately
    • Understand comparatives like loud, louder, loudest
    • Listen to long stories (but may misinterpret the facts)
    • Understand sequencing of events when clearly explained (for example, “First we plug the drain, then we run the water, and finally we take a bath”)

    WISC Subtests

    This post describes the individual subtests of the WISC-IV. For more general information on the WISC-IV, see the main post.

    NB: If you are going to be tested on a WISC-IV in the near future, it is better to read this information after you have completed the test. This will ensure the results of your test are as accurate as possible.

    Subtests:

    The individual subtests of the WISC-IV are:

    Similarities: Assesses ability to perceive underlying relationships and develop concepts verbally. Participants are required to listen to two words and assess how they are similar.

    Vocabulary: Measures the student’s knowledge of word meanings. Participants are asked to tell the administrator what each word means.

    Comprehension: Assesses practical commonsense reasoning about the world the participant experiences.  Participant’s are asked the reason behind common rules and occurances.

    Block Design: Assesses visual conceptualisation and analysis. Participants are asked to arrange blocks into a shape which resembles a picture.

    Matrix Reasoning: Taps the ability to reason with non-verbal information through recognising spatial patterns. Participants need to recognize a pattern and pick the next part of the sequence of that pattern.

    Picture Completion: Measures attention to visual detail. Participants need to look at a complex picture and recognize what is missing.

    Digit Span: Assesses short term verbal memory and sequencing ability. Participants are told a series of numbers and asked to repeat them back, using only their memory.

    Letter Number Sequencing: Assesses verbal working memory. Participants are told a series of numbers and letters and are asked to repeat them back in a certain order.

    Coding: Taps the ability to handle symbolic materials and his/her visual motor speed. Participants need to rapidly match symbols with numbers.

    Symbol Search: Assesses visual search abilities in response to symbolic stimuli. Participants need to rapidly check if a certain symbol exists in a set of symbols.

    For more information on the WISC-IV see the main post.

    Wisc Test

    The Weschsler Intelligence Scale for Children (WISC-IV) is one of the gold standard tests of intelligence. This compehensive description of the WISC-IV gives information on:

  • Overview
  • What to expect if you are going to be assessed using a WISC-IV
  • What the results mean
  • For clinicians
  • Overview

    The WISC-IV measures intelligence and yields an IQ score. However, it can be used for much more than just a measure of general intelligence. The WISC-IV is made up of a series of sub-tests which measure different aspects of cognition. The subtests are grouped into certain types of cognitive abilities. Often clinicians and researchers  use these individual groups of subtests to determine an individual’s strengths and weaknesses rather than looking at their total IQ score. It is the ability to make fine grained analyses of an individual’s cognitive abilities that makes the WISC-IV such a useful tool.

  • Back to top
  • What to expect

    There is only limited information that can be given to prepare someone for the WISC-IV as it is important each person only knows the same information going into the test.

    The WISC-IV involves a participant sitting down with a psychologist or psychiatrist for around 1.5 – 2 hours. The administrator will ask you to do a number of different tasks for them, arranged by subtests. Many people will find that the start of each subtest is easy and the items get progressivly harder. Some of the tasks you will be asked to do will be writing with a pencil and paper, manipulating blocks, and pointing out certain stimuli in a book.

    Each person’s WISC-IV experience differs based on the administrator and the individual. However, the majority of people do not find the WISC-IV too intrusive or adversive. Each subtest is a unique challenge and they change regularly.

    A skillful administrator will administer the tests to children as games and activities. If done correctly, children will often enjoy the test and the time will be over before they know it.

  • What the results mean

    NB: If you are going to be tested on a WISC-IV in the near future, it is better to read this information after you have completed the test. This will ensure the results of your test are as accurate as possible.

    You have been tested on a WISC-IV and got the report back. What do the results mean? Below is a guide to interpretation:

    Interpreting Scores – The Percentile Rank

    WISC-IV scores are given as a score with a percentile rank. The percentile rank shows how many students of the same age would perform equal to or worse than your child. For example, if your child is on the 50th percentile, they have performed equal to or better than 50% of students the same age. If they are on the 30th percentile, they have performed equal to or better than 30% of students the same age. The average percentile is 50%, and the majority of students will achieve a score around this number. The graph below shows the relative number of students at each percentile rank.

    IQ score:

    The IQ score is a measure of general intelligence. For more information see the post on IQ scores. It is important to note that IQ scores are not accurate and should not be interpreted unless your scores on the WISC indexes are all similar.

    Indices

    The WISC subtests are grouped into indices – each subtest in an index is designed to measure a similar thing in a different manner. They can be used to examine someone’s strengths and weaknesses in different areas. The WISC indices are:

    Verbal Comprehension Index:

    Measures the ability to use verbal skills in reasoning and problem solving and the capacity to learn verbal material. This index is a good predictor of readiness for school and achievement orientation, but can be influenced by background, education, and cultural opportunities.

    Subtests: Similarities, Vocabulary, and Comprehension Subtests

    Perceptual Reasoning Index:

    Assesses nonverbal reasoning skills and the ability to use visual images in thinking about both abstract and concrete information. These skills are very important in problem solving and learning new information.

    Subtests: Block Design, Picture Concepts and Matrix Reasoning

    Working Memory Index:

    Assesses the ability to maintain verbal information in memory, manipulate that information, and then reproduce it. This can be very important for things like remembering multi-step instructions at home and at school.

    Subtests: Digit Span and Letter Number Sequencing

    Processing Speed Index:

    Measures the speed with which an individual can process and complete simple tasks. An individual with slow processing speed will take longer to complete tasks than someone with fast processing speed.

    Subtests: Coding and Symbol Search

    More information on the individual WISC-IV subtests, see the seperate post.

    The WISC-IV is an extremely useful tool when administered and interpreted by a professional. However, the results are complex and need to be interpreted in context. Most administrators of the WISC-IV will be happy to answer additional questions about their report and should be contacted if you are unclear about anything.
