Table 1.

Examples of features generated by healthy comparison participants (CO) and patients with hippocampal damage (HP) for the target words “book” and “grapefruit.”

Group	Target word	Feature (word similarity below)				Cosine
CO	Book	Can be bound in either leather or paper				0.2911
			0.2328	0.1809	0.4542
HP	Book	Something you read				0.4686
		0.3614	0.5758
CO	Grapefruit	Often	produced in Florida			0.0531
		–0.0674	0.0560	0.1708
HP	Grapefruit	Skin	like	oranges		0.2829
		0.1805	0.0666	0.6017

Bolded words in each feature indicate which words were included in the analysis after the exclusion of non-content words. Underneath each bolded word is the cosine similarity score between that word and the target word. These values were averaged to create the overall cosine similarity score for the feature, which is given in the rightmost column.
