How does age affect vocabulary?
Compared to younger adults, older adults have larger vocabularies. They “know more words, know what they mean, and know that they know them.” It might seem obvious that the longer you've been around, the more you've learned, but it's encouraging that the ability to do that learning stays strong.
Whereas some cognitive functions decline with age, general knowledge, vocabulary, and other measures of crystallized knowledge are stable or improve across the life span (Salthouse, 2009, 2010, 2014).
While verbal intelligence (vocabulary) remains unchanged with aging, the speed of information processing gradually slows (such as problem-solving skills).
Some of the signs of age-related speech changes aren't always easily recognizable, and can include: Hoarseness and changes in pitch. Difficulty related to the production of certain sounds or saying specific words. Difficulty swallowing.
Background: Vocabulary scores increase until approximately age 65 years and then remain stable or decrease slightly, unlike scores on tests of other cognitive abilities that decline significantly with age.
This is because neuroplasticity generally decreases as a person gets older, meaning the brain becomes less able to change itself in response to experiences. Some aspects of language learning become progressively more difficult with age, others may get easier.
Your vocabulary skills are sharpest around age 67. Scores on multiple-choice vocabulary tests show that most people reach their peak vocabulary abilities in their late 60s or early 70s.
In fact, our study members demonstrated large gains in vocabulary between the ages of 16 and 42. At age 16, their average vocabulary test score was 55%. By age 42, study members scored an average of 63% on the same test.
The vocabulary spurt, word burst, or naming explosion (or any combination) refers to an apparent acceleration in the rate at which children acquire new words, usually between 18 and 24 months.
In old age, it takes increasingly longer to find a certain word. Researchers have discovered that this is due to a change in the use of certain networks in the brain. Not only in games, but also in conversation, we sometimes run out of words.
What causes loss vocabulary?
Aphasia usually happens suddenly after a stroke or a head injury. But it can also come on gradually from a slow-growing brain tumor or a disease that causes progressive, permanent damage (degenerative). The severity of aphasia depends on a number of things, including the cause and the extent of the brain damage.
There were some factors that caused students' difficulties in learning vocabulary (1) the written form is different from the spoken form in English, (2) The nuber of words that students need to learn is exceedingly large, (3) the limitations of sources of information about words, (4) The complexity of word knowledge.
However, not all thinking abilities decline with age. In fact, vocabulary, reading and verbal reasoning remain unchanged or even improve during the aging process.
The first age-related decline in category fluency is in part influenced by the slowing of information processing; however, a significant portion of the decline is still independent of the decline in processing speed.
As people get older, the larynx (voice box), vocal folds (cords), and voice-producing mechanism age along with the rest of the body. Age-related voice changes develop as muscle and other tissues in the larynx and vocal cords shrink, thin, and stiffen.
They concluded that the ability to learn a new language, at least grammatically, is strongest until the age of 18 after which there is a precipitous decline. To become completely fluent, however, learning should start before the age of 10.
The brain's capacity for memory, reasoning and comprehension skills (cognitive function) can start to deteriorate from age 45, finds research published on bmj.com today.
It's strongly believed that once we hit 25, the brain's plasticity solidifies. This makes it harder to create neural pathways. In turn, this can mean it's tougher to learn new skills.
It is true that older language learners will have to work a bit harder than young ones. A study from researchers at Harvard and MIT found that children are able to absorb new languages faster than adults until the age of 18 or 19, and that the ideal age to learn a language is before 10.
Across multiple sources, Mandarin Chinese is the number one language listed as the most challenging to learn. The Defense Language Institute Foreign Language Center puts Mandarin in Category IV, which is the list of the most difficult languages to learn for English speakers.
How does age difference affect language learning?
When examining age on arrival, most studies of both short-term and long-term acquisition find that students arriving between the ages of 8 and 12 are faster in early acquisition of second language skills, and over several years' time they maintain this advantage over younger arrivals of 4 to 7 years.
Scientists have long known that our ability to think quickly and recall information, also known as fluid intelligence, peaks around age 20 and then begins a slow decline.
Hatch and Brown (1995) suggested a model to learn new words consisting of five steps: "Encountering new words", "Getting the word form", "Getting a clear image", "Learning the meaning of the word", and "Using the word".
A clear decline is evident.
The mean WAIS-IV IQ is 100 for ages 20-24 and is 99 for ages 25-44. Then it drops to 97 for ages 45-54, to 94 for ages 55-64, to 90 for 65-69, to 86 for ages 70-74 and to 79 for ages 75+.
Most students acquire vocabulary incidentally through indirect exposure to words at home and at school—by listening and talking, by listening to books read aloud to them, and by reading widely on their own. The amount of reading is important to long-term vocabulary development (Cunningham and Stanovich, 1998).
Speech-language pathologists often state a child should be saying 10 words by 15 months, 50 words by 18 months, and 200-300 words by 24 months! Whereas the AAP, CDC or Mayo Clinic states that a child should say 10 words by 18 months or 50 words by 24 months.
At age one, children recognize about 50 words; by age three, they recognize about 1,000 words; and by age five, they recognize at least 10,000 words (Shipley & McAfee, 2015).
The vocabulary spurt is defined by a rapid acceleration of the pace at which toddlers add new words to their productive vocabulary. As can be seen in Figure 3, in the first few months after children produce their first word, new words are added to the vocabulary slowly—one or two a week.
The top quarter of pupils know about 7,100 words by age seven, and add about three new ones each day. The bottom quarter have fewer than half as many words at that age – about 3,000; they acquire only about one word a day, so the gap continues to widen.
The words that children tend to say first are naming words (Nouns and Proper Nouns). Then action words (Verbs) are the second earliest type of word. Other words which are learnt early on are a few examples of modifiers (for example 'more'), and personal-social phrases (for example 'please', 'no').
Why do I forget common words when speaking?
PPA is caused by degeneration in the parts of the brain that are responsible for speech and language. PPA begins very gradually and initially is experienced as difficulty thinking of common words while speaking or writing. PPA progressively worsens to the point where verbal communication by any means is very difficult.
Introduction: The five-word test (5WT) is a serial verbal memory test with semantic cuing. It is proposed to rapidly evaluate memory of aging people and has previously shown its sensitivity and its specificity in identifying patients with AD.
The answer is you are likely to have been “dual-tasking” just before speaking. It might have been because you were thinking about the words you wanted to say and something else at the same time. Or maybe you were concentrating on listening while trying to think of what to say.

The loss or decline of language and communication skills is called aphasia. This is an acquired language disorder that affects a person's ability to comprehend and produce language.
Vocabulary development is affected by a student's exposure to language through real-world experiences, a range of reading materials, and the child's ability to apply context to decipher unknown words.
Background: This research explored the relative impact of demographic, cognitive, behavioural, and psycholinguistic factors on vocabulary development in two-year-old children.

What cognitive skill most consistently declines with age?
Memory. One of the most common cognitive complaints among older adults is change in memory. Indeed, as a group older adults do not perform as well as younger adults on a variety of learning and memory tests.
In general, however, the symptoms of cognitive decline that are associated with aging include: Slower inductive reasoning / slower problem solving. Diminished spatial orientation. Declines in perceptual speed.
Numerous studies have shown that ageing also affects language processing. Even neurologically healthy people speak, retrieve words and read more slowly as they get older.
Seniors may lose their ability to talk or understand language—a condition known as aphasia—due to ailments like stroke, Alzheimer's disease, Parkinson's disease or brain injury. There are many types of aphasia and the severity of symptoms varies from person to person.
If you talk too long, cheer too loudly, sing too much or speak in a pitch that's higher or lower than usual, you may experience hoarseness. Also, your vocal cords naturally get thin and limp with age. It's perfectly common for your voice to get raspier as you get older.
As your larynx grows, your vocal cords grow longer and thicker. Also, your facial bones begin to grow. Cavities in the sinuses, the nose, and the back of the throat grow bigger, creating more space in the face that gives your voice more room to echo. All of these factors cause your voice to get deeper.
Typically, voice change begins somewhere around age 12 or 13, or during the middle school years, which can make the experience a tad embarrassing for the child.
Researchers have long known that at about 18 months children experience a vocabulary explosion, suddenly learning words at a much faster rate. They have theorized that complex mechanisms are behind the phenomenon.
Language is always changing, evolving, and adapting to the needs of its users. This isn't a bad thing; if English hadn't changed since, say, 1950, we wouldn't have words to refer to modems, fax machines, or cable TV. As long as the needs of language users continue to change, so will the language.
Age-related increases in language knowledge. Increasing age yields increasing lexical knowledge in both monolingual and bilingual speakers, due to greater cumulative exposure to the target language.
What causes poor vocabulary?

A vocabulary spurt is a point in which a child may display a sudden growth in their spoken vocabulary. This occurs when a child switches from early language learning of approximately two words per week per week to suddenly acquiring and using around 20 new words per week.
At 18 months, most children have a vocabulary of from 5 to 20 words, although some do reach the 50-word milestone by the time they are 2 years old. In their second year, most children increase their vocabulary to up to 300 words.
