gate warnings, the novices had more concepts relating to the RLX and RLX infras-
tructure, whereas experienced drivers also had concepts related to scanning and
checking the environment e.g. ‘clear’, ‘look’, ‘ahead’.
Manual network construction
Ten SA networks were manually constructed for each participant. To summarise
this analysis, frequency counts of the concepts within the networks were under-
taken. Similar to the Leximancer™ analysis, this revealed that a key difference
between the experienced and novice driver SA networks was the presence of con-
cepts ...
