Document Summary
Infants don"t talk, can"t ask how they"re thinking, what they know. Sucking habituation paradigm: experimenters measure how quickly infants suck on a pacifier: will suck more quickly in response to novel stimuli. Conditioned head turn technique: the researchers use reinforcement to teach infants to turn their heads whenever they detect a change in the stimulus. Cross-sectional studies: looking at children at many different ages, and compare them all to one another: huge linguistic variation between children even with the same age relatively quick to gather data from many time points across development. Longitudinal studies: take children and track them through time, at different points during development: provide detailed look at how language changes within an individual time consuming and participants may drop out. Walks , non-pro-drop language: through exposure, we learn to switch the pro-drop parameter on or off, parameters are hard to define.
