CHAPTER 4. PSYCHOLINGUISTIC EXPERIMENTS 153<br />

cussed in the preceding section, i.e., (1) eye-faculty, (2)ensure-determine-recognize,<br />

<strong>and</strong> (3)setting- experience. T-tests were then performed to test the signi cance of di er-<br />

ences between these groups, using both methods of h<strong>and</strong>ling missing cases. Using listwise<br />

deletion, signi cant di erences are found between groups 1 <strong>and</strong> 2 <strong>and</strong> between2<strong>and</strong>3;<br />

signi cant di erences are found between groups 1 <strong>and</strong> 3 using either deletion method. No<br />

signi cant di erences are found between senses within the proposed clusters with either<br />

deletion method.<br />

Returning to Table 4.5 on the preceding page, the pattern of results from the<br />

lexical decision task is not so clear, <strong>and</strong> grouping as before does not yield the same pattern<br />

of signi cant di erences. We note that, with the exception of determine, the two senses<br />

having to do with physical vision (eye <strong>and</strong> faculty) are faster than the others; this<br />

makes sense from a cognitive point of view, with \concrete" senses accessed faster than<br />

\metaphorical" ones. The reason for the unexpectedly speedy reactions to determine <strong>and</strong><br />

setting is still being sought. There may be additional noise in this task due to perceived<br />

similarities between some of the keywords <strong>and</strong> some of the non-words, despite our e orts<br />

to create a set of uniform, unrelated, English-sounding non-words.<br />

Discussion<br />

In general, the subjects distinguished among the senses reliably on at least three<br />

out of the four tasks. They were able to underst<strong>and</strong> <strong>and</strong> follow the instructions <strong>and</strong> their<br />

unrestricted categories (from the Sorting task) were generally in accord with those used by<br />

the experimenters.<br />

Since the results showed that the subjects were able to h<strong>and</strong>le 7 senses well, we<br />

decided carry out a new experiment, adding 7 more senses to the stimuli, to bring us closer<br />

to the numbers of senses hypothesized on linguistic grounds in Chapter 2.<br />
