IFG3 lists the following perception verbs:perceive, sense, see, notice, glimse, hear, overhear, feel, taste, smellAnd note these can all project (with reservations on the last two):I perceived that he was uneasy.
I sensed that he was uneasy.
I saw that he was uneasy.
I noticed that he was uneasy.
I glim[p]sed that he had the Joker.
I heard that you won.
I overheard that you like cheese.
I felt that I should leave.
? I smelt that she had been here
? I tasted that she had used garlic
There are two problems here.
 The first problem is O'Donnell's continual mistaking of embedded clauses for projected ones, as demonstrated in previous critiques. As a general guide, whenever that can be replaced by the fact that, we know we are dealing with a 'fact' clause, and so with a clause that is embedded as a constituent within another clause.
 The second problem is the analytical mistake of using the verb itself as the point of departure for determining the process type of a particular clause. A specific verb can serve as various types of Process, as when see functions as a mental process of cognition, rather than perception.
