ERP amplitudes at electrode Fz restricted to the 100 to 175 millisecond time window.

Description

Event-related brain potential data recorded from 10 participants at electrode Fz (100–175 ms) in the context of Antoine Tremblay's PhD thesis (Tremblay, 2009). The actual raw data was averaged over variables LengthBc and WMCc.

Usage

data(erpFz)

Format

A data frame with 120 observations on the following 3 variables.

LengthBc

A numeric vector. The mean-centered length (in number of letters) of the second word of a four-word sequence.

WMCc

A numeric vector. The mean-centered working memory capacity of the participants.

Amplitude

A numeric vector. The avereaged amplitude of the recorded ERPs.

summary(erpFz)

Plotting data generated from a linear mixed-effects model from Tremblay & Newman (In Preparation).

Description

The model call is: lmer(formula = Amplitude ~ FreqBc * LengthBc * WMCc + (1 | Subject) + (1 | Item) + (0 + WMCc | Item), data = dat)

(see details for more).

The plotting data was generated from this model with function plotLMER3d.fnc.

Usage

data(z)

Format

The format is: num [1:30, 1:10] -1.83 -1.95 -2.07 -2.19 -2.32 ... - attr(*, "dimnames")=List of 2 ..$ : chr [1:30] "-2.88262910798122" "-2.50331876315363" "-2.12400841832605" "-1.74469807349846" ... ..$ : chr [1:10] "-0.1857142855" "-0.1410714285" "-0.0517857144999999" "-0.0428571424999999" ...

Details

The model includes a three-way interaction between WMCc (mean-centered working memory capacity), FreqBc (the frequency of use of the second word of a four-word sequence), and LengthBc (the length in number of letters of the second work of a four-word sequence) in addition to by-subject and by-item random intercepts and by-item random slopes for WMCc.
