Class 7 - Language acquisition/learning Flashcards
High Amplitude Sucking (HAS)
A sound is presented to the infant every time a strong or “high amplitude” suck occurs. Infants quickly learn that their sucking controls the sounds, and they will suck more strongly and more often to hear sounds they like the most.
Headturn paradigm
The infant is put on the parent laps (people who babies trust and know): the parent has headphones so does not know what the baby is hearing: they sit in a cabin which has a lamp in the center and the experimenter sees the baby via a camera. The
baby does not see the experimenter nor the caregiver. The experimenter starts coding when the stimulus is presented (a blinking light) and records the time the baby takes to get bored about the light. At this moment, the experimenter records the time and then presents the light on the other side and does the same thing. If the infant perceives the stimulus in a different way, he/she will look shorter/longer depending on the age.
Baby/newborn
0-2 months
Infant
3-12 months
Toddler
3-12 months
Children start to perceive airborne sounds at…
30 weeks of pregnancy (detected via heart beat monitoring of infants)
Rhythmic information
Infants at only 2 days old can distinguish their native language’s rhythm, proven by studies which used the HAS.
Approximately from 4 to 8 months, infants…
prefer what it’s familiar to them
Approximately from 8 months onwards, infants…
prefer novelties (should be considered when conducting experiments with infants in this ranges)
Statistical learning
ability for humans and other animals to extract statistical regularities from the world around them to learn about the environment. Although statistical learning is now thought to be a generalized learning mechanism, the phenomenon was first identified in human infant language acquisition.
Statistical learning
It can be divided into subgroups:
- Hebbian learning (which relies on regularity, frequency distribution, probability)
- Categorical learning / perception
- Transitional probability
- Stress patterns
Hebbian learning
Biology: form of activity-dependent synaptic plasticity where correlated activation of pre- and postsynaptic neurons leads to the strengthening of the connection between the two neurons.
Linguistics: learning rule that specifies how much the weight of the connection between two units should be increased or decreased in proportion to the product of their activation.
Categorical perception
refers to the ability that listeners can distinguish cross-category stimuli, but cannot discriminate different stimuli within the same category. The degree of categorization for lexical tone perception may be influenced by the acoustical similarity of different tones.
Categorization
The process in which experiences and concepts are recognised and understood.
Categorization is central issue in Cognitive Linguistics in which it is argued to be one of the primary principles of conceptual and linguistic organization.
Is the magnet effect a language-specific phenomena?
Yes
