Data from a probe experiment testing whether immediate memory for
sentenses is influenced by the phrase structure of the sentence.
The data sets come from Timm (1975), Ex. 3.14 and Ex. 3.16 (p.244)
Procedure: Subjects listened to tape-recorded sentences. Each
sentence was followed by a "probe word" from one of 5 positions
within the sentence. The subject had to respond with the word
which immediately followed the probe word in the sentence. The
dependent measure is response speed = k(1/reaction time).
Sample sentence:
* The tall man met the young girl who got the new hat.
Pos'ns: 1 2 3 4 5
Function: ADJ1 SUBJ ADJ2 OBJ REL.PN
In Probe2, there are two groups of subjects,
pre-selected on a test of short term memory.
Usage
data(Probe1)
data(Probe2)
Format
Probe1: A data frame with 11 observations on the following 5 variables.
p1
speed at position 1
p2
speed at position 2
p3

p5
speed at position 5
Probe2: A data frame with 20 observations on the following 6 variables.
stm
Short term memory capacity: a factor with levels HighLow

Details
These data sets (fictitious) are used as examples of single-sample and two-sample
profile analysis or simple repeated measure designs with structured
contrasts.
