In JAQuent/memoryROC: A package to analyse recognition memory data within R.

Estimation of recollection and familiarity using the ROC Remember/Know procedure

Description

This function allows to estimate recollection and familiarity using Remember/Know procedure. In this procedure, recollection is given by the probability that an old/studied item were given a remember response, while familiarity is given by the probability that an old/studied item were given a know response divided by the probability that an old/studied item were not given a remember response.

recollection = P(remember)

familiarity = P(know)/(1 -P(remember))

Usage

rememberKnow(
  rememberLevels,
  knowLevels,
  confidenceRatings,
  oldNew,
  oldNewLevels = c(0, 1)
)

Arguments

rememberLevels	A value indicating the code for the remember response.
knowLevels	A vector containing the codes for the know responses.
confidenceRatings	An vector containing recognition responses coding remember and know responses.
oldNew	An vector coding whether an item was new/not-studied or old/studied.
oldNewLevels	An vector containing possible levels of old_newInformation. The first value or level is for new/not-studied items and the second value is for old/studied items. Defaults to c(0,1).

Details

The value of recollection is represented by the probability of a remember response for old items. The value of familiarity is represented by the probability for a know response for old items divided by 1 - recollection.

Value

The function returns a list with components:

recollection	The estimation of recollection.
familiarity	The estimation of familiarity.
