Local lexical

The goal of the chapter is to evaluate these possibilities. More specifically, three experiments are discussed that use the metaphor consistency effect to discount the local lexical relations possibility. Then, other literature is reviewed that contrasts the remaining three alternatives. 

We conducted a second study to guard against the possibility that local lexical associations led to the Consistency effect. In this experiment we took advantage of a small set of spatio-temporal terms that can be used in both the ego-moving and time-moving metaphors, but which convey the opposite temporal order in the two systems. This set includes before, ahead and behind. This sequence reversal is exemplified in the following two sentences.

The eode in this example illustrates several language features such as die do. end loop, the if... then. .. end loop and a function definition. The code also illustrate some features of the lexical scope of Lua variables wifli the printO statement on line 18. It is noted that variables x, y and z are first introduced within the body of the tst() function definition. However, y is declared as a local variable and is thus known only within the scope of the code block in which it is defined, which in this case is within lines 6 through 13 of the code. The attempt to print the value of y on line 18 thus results in the printed value of nil indicating an unknown value. This illustrates the fact that in Lua, variables are known globally unless restricted to a code block by the local keyword, i.e. die default is that all variables have global scope.
