Infants also begin laughing at this stage. At 6–7 months old, infants begin to respond to their own name, yell and squeal, and distinguish emotions based on the tone of voice of the parent. Between 7 and 10 months the infant starts putting words together, for example "mama" and "dada", but these words lack meaning and significance.
Their perceptual system has been tuned to the contrasts relevant in their native language. As for word comprehension, Fenson et al. (1994) tested 10-11-month-old children's comprehension vocabulary size and found a range from 11 words to 154 words. [13] At this age, children normally have not yet begun to speak and thus have no production ...
By 10 to 12 months, infants can no longer discriminate between speech sounds that are not used in the language(s) to which they are exposed. [4] Among six-month-old infants, seen articulations (i.e. the mouth movements they observe others make while talking) actually enhance their ability to discriminate sounds, and may also contribute to ...

Since Piaget's contribution to the field, infant cognitive development and methods for its investigation have advanced considerably, with numerous psychologists investigating different areas of cognitive development including memory, language and perception, coming up with various theories [4] —for example Neo-Piagetian theories of cognitive ...
A 10-month-old infant who was found not breathing Monday afternoon at a Homestead daycare was rushed to an area hospital, where doctors failed in a desperate attempt to save his life.
This capability may be innate. Speech perception becomes language-specific for vowels at around 6 months, for sound combinations at around 9 months and for language-specific consonants at around 11 months. [4] Infants detect typical word stress patterns, and use stress to identify words around the age of 8 months. [4]
