Primed lexical decision latencies for Dutch neologisms ending in the suffix -heid, with information on RTs to preceding trials added to the data already in primingHeid.

1	data(primingHeidPrevRT)

A data frame with 832 observations on the following 17 variables.

Subject: a factor with subjects as levels.
Word: a factor with words as levels.
Trial: a numeric vector for the rank of the trial in its experimental list.
RT: a numeric vector with log-transformed lexical decision latencies.
Condition: a factor coding the priming treatmen, with levels baseheid (prime is the base word) and heid (the prime is the neologism)
Rating: a numeric vector for subjective frequency estimates.
Frequency: a numeric vector for log-transformed frequencies of the whole word.
BaseFrequency: a numeric vector for the log-transformed frequencies of the base word.
LengthInLetters: a numeric vector coding orthographic length in letters.
FamilySize: a numeric vector for the log-transformed count of the word's morphological family.
NumberOfSynsets: a numeric vector for the number of synonym sets in WordNet in which the base is listed.
ResponseToPrime: a factor with levels correct and incorrect for the response to the prime.
RTtoPrime: a numeric vector for the log-transformed reaction time to the prime.
RTmin1: a numeric vector for reaction time in ms to the item preceding the target.
RTmin2: a numeric vector for reaction time in ms to the item preceding the target by two trials.
RTmin3: a numeric vector for reaction time in ms to the item preceding the target by three trials.
RTmin4: a numeric vector for reaction time in ms to the item preceding the target by four trials.
