Usage

data("PairClustering")

Format

A data frame containing 126 observations on 8 variables.

ID

Participant ID.

trial

Trial number, 1 or 2.

E1

Number of pairs recalled adjacently.

E2

Number of pairs recalled non-adjacently.

E3

Number of single pair members recalled.

E4

Number of non-recalled pairs.

F1

Number of recalled singleton words.

F2

Number of non-recalled singleton words.

Details

Klauer (2006) reports a pair-clustering experiment with 63 participants, who were presented with ten pairs of related words and five unrelated singleton words. In a later memory test, they freely recalled the presented words. This procedure was repeated for two study and test trials. For pairs, responses were classified into four categories: both words in a pair are recalled adjacently (E1) or non-adjacently (E2), one word in a pair is recalled (E3), neither word in a pair is recalled (E4); for singletons, into two categories: word recalled (F1), word not recalled (F2).
