- Babbling (Canonical Babbling, Prelinguistic Vocalization)
- The repetitive, syllable-like vocalizations produced by infants typically between 6 and 12 months of age as a precursor to spoken language. Babbling progresses through developmental stages from simple…
- Canonical Syllable (Canonical Babbling, Well-Formed Syllable)
- A canonical syllable is a well-formed syllable in infant babbling that consists of a consonant-like closure (closant) produced by an oral cavity constriction followed by a vowel-like opening (vocant).…
- Child Agency
- Child agency is a child's capacity to initiate, shape, direct, and sustain activities - including play, conversation, and social interaction - rather than passively accepting adult or peer control. In…
- Developmental Apraxia of Speech (Childhood Apraxia of Speech, CAS, DAS, Verbal Dyspraxia)
- A motor speech disorder in which children have difficulty planning and coordinating the movements needed for speech, despite having no muscle weakness. Children with developmental apraxia of speech kn…
- Infant-Computer Interaction (Baby-Computer Interaction)
- The design and study of technology interfaces intended for use by infants, typically under 24 months of age. Infant-computer interaction presents unique challenges compared to other user populations b…
- Language-Based Learning Impairment (LLI, Language Learning Impairment, Language Learning Disability)
- A developmental condition in which children have difficulty acquiring language and later reading skills while other cognitive abilities appear relatively intact. Language-based learning impairments af…
- Operant Conditioning (Instrumental Conditioning, Operant Learning)
- A learning process in which behaviour is modified by its consequences — specifically, by reinforcement (rewards that increase the likelihood of the behaviour) or punishment (consequences that decrease…
- Peer Culture
- Peer culture is the body of shared understandings, values, social norms, communication practices, and play conventions that children co-construct among themselves through daily interaction - distinct …
- Phonological Development (Speech Sound Development, Phonological Acquisition)
- The process by which children learn to produce and organise the speech sounds of their language, progressing from early cooing and vowel-like sounds through canonical babbling (consonant-vowel syllabl…
- Pre-speech Vocalizations (Pre-linguistic Vocalizations, Infant Vocalizations)
- Sounds produced by infants before the development of recognizable speech, including cooing, babbling, and other vocal productions. Pre-speech vocalizations are important predictors of later articulati…
- Prelinguistic Development (Pre-Speech Development, Prelinguistic Communication)
- Prelinguistic development refers to the stages of vocal and communicative development that occur before an infant produces meaningful words, typically spanning from birth to approximately 12-18 months…
- Rapid Auditory Processing (RAP, Auditory Temporal Processing)
- The ability to perceive and process rapidly changing auditory signals that occur within tens of milliseconds, such as the rapid frequency and amplitude transitions that characterise speech sounds. Rap…
- Social Play
- Social play is intrinsically motivated, voluntary activity between two or more children that has no purpose beyond itself, yet is essential to emotional, cognitive, and social development. Development…
- Specific Language Impairment (SLI, Developmental Language Disorder)
- A neurodevelopmental condition characterised by significant difficulties in acquiring and using language that cannot be attributed to hearing loss, intellectual disability, neurological damage, or env…
- Vocalization Analysis (Vocal Analysis, Infant Vocalization Analysis)
- Vocalization analysis is the systematic study and measurement of vocal productions, including speech, pre-speech sounds, and non-speech vocalizations. In developmental and clinical contexts, vocalizat…
