Document Summary
Searching as a function of attention: searching can consume attentional resources and inhibit learning - searching for an important thing amongst many unimportant things. Distractions: students are easily distracted, tuning in to other conversations (sounds), looking out the window (visuals), thinking of other matters (internal cognition) etc, concentration is dependent on attention. Summary: attention is limited, processing can be automatic or controlled, automatic processing uses much less attention, teachers need to help students develop automatic processing. Working memory processing capacity: transitive interference problems: halford, maybery, and bain (1968, a is larger than b, b is larger than c, b is larger than c, a is larger than b. The integration requires considering relations between all the elements concurrently: reconsideration of wm capacity when processing is involved (cowan, 2001) In terms of processing information, 4 is a more likely number than 7.
