Taft & Forster (1975): A bound stem like VIVE (which comes from the prefixed word revive)
takes longer to reject in a lexical decision task than KIVE . And vive also had more errors. So
suggests that VIVE has a representation in lexical memory. Ppl think of vive as a word
We dk if its important cos it’s a morpheme or part of a word
So we need word like LISH which r part of a word but not a morpheme. → reLISH. And reVIVE.
So both r similar, just removing re.LISH is pseudoprefixed word, looks like prefixed word but
isn’t. unlike revive which is prefixed.in revive re conveys a function, NOT the re in relish
Lish behaved like kive. Vive > lish. So this shows its abt it being a morpheme, but just end of
word.
So subunit vive isn’t a word in itself, represents a morpheme. so morpheme level of
representation exists?
However, to suggest that the orthographic system has a morpheme level of representation isn't
entirely logical because a morpheme, by definition, is a subunit that has meaning. Yet the
orthographic system is supposed to be purely form-based (with meaning represented elsewhere).
For this reason, it makes more sense for morpheme representations to exist somewhere between
the form-level (i.e., the orthographic and phonological subsystems) and the semantic level.
So morpheme level links form w function
If meaning is represented at the semantic level in terms of semantic features, then there can be
a level which brings together the relevant semantic features with the form
representation(lemma, concepts) . intermediate level
Specific knowledge u have abt sticks or specific sticks r linked to lemma
Bottom STICK is connected to the letter y as well
Taft & Nguyen-Hoan (2010) support the lemma model by looking at the meaning given to a
target -an ambiguous word (e.g., STICK) when preceded by a visual masked prime. Stick has 2
meanings. Task was to see which meaning of stick was the 1st word ppl thought of.
There was a control condition like house STICK. And then words like adhere, or sticky, being a
prime.
When the prime was morphologically related to only one meaning of the target (e.g., sticky
STICK) it biased the interpretation of the target toward that meaning (i.e., the "adhere" meaning)
compared to an unrelated prime. It was argued that such a bias could only arise at the lemma level
because the two versions of the ambiguous word (e.g., STICK meaning "adhere" and STICK

So both r similar, just removing re. lish is pseudoprefixed word, looks like prefixed word but isn"t. unlike revive which is prefixed. in revive re conveys a function, not the re in relish. So this shows its abt it being a morpheme, but just end of word.
