OAEs are considered to be related to the amplification function of the cochlea. In the absence of external stimulation, the activity of the cochlear amplifier increases, leading to the production of sound. Several lines of evidence suggest that, in mammals, outer hair cells are the elements that enhance cochlear sensitivity and frequency selectivity and hence act as the energy sources for amplification. One theory is that they act to increase the discriminability of signal variations in continuous noise by lowering the masking effect of its cochlear amplification.
- Promotion of the time-out technique for dealing with inappropriate behaviour (p173). I've worked with enough children in my career and read enough literature on child behaviour and development to know that time-out is an ineffective, overused and misunderstood tool that adults resort to when they have no clue otherwise how to deal with their child's actions (thank you Super Nanny). In many cases it's the parents who need time out from the situation to cool down and gather their composure. I'm not about to tell anyone how to parent, but I will say that when a child is sent to time-out to 'think about their behaviour', you can be guaranteed they're thinking of anything BUT that.
