Background to the Multiple Personality Data

Data analysed in: Kroonenberg, P. M. (2008). Applied multiway data analysis. Hoboken NJ: Wiley.

The present data set comes from probably the most famous case of a multiple personality (Osgood & Luria, 1954). In each personality, Eve White, Eve Black, and Jane produced scores on 10 semantic differential scales about concepts related to her present life and mental state for 15 concepts. Previous three-mode analyses of these data have appeared in Kroonenberg (1983) and Kroonenberg (1985).

Data description

Osgood & Luria (1954) published the scores on semantic differential scales for each of the three personalities Eve White, Eve Black, and Jane measured at two occasions (Testings I and II). In essence, the data are a four-way data set concepts by scales by personalities by testings. We will, however, treat them here as a three-way set with 15 concepts x 10 scales x 6 administrations.

Rows (1st mode): Concepts

No.	Abbreviation	Description
1.	Love	Love
2.	Child	my Child
3.	Doctor	my Docotor
4.	Me	Me
5.	Job	my Job
6.	Sickns	Mental illness
7.	Mother	my Mother
8.	Peace	Peace of mind
9.	Fraud	Fraud
10.	Spouse	my Spouse
11.	Contrl	Self control
12.	Hatred	Hatred
13.	Father	my Father
14.	Confus	Confusion
15.	Sex	Sex

Columns (2nd mode): Scales

No.	Abbreviation	Description
1.	Hot	Hot - Cold
2.	Worthl	Worthless - Valuable
3.	Relaxd	Relaxed - Tense
4.	Large	Large - Small
5.	Fast	Fast - Slow
6.	Clean	Clean - Dirty
7.	Tasty	Tasty - Distasteful
8.	Weak	Weak - Strong
9.	Deep	Deep - Shallow
10.	Active	Active Passive

Slices (3rd mode): Personalities

No.	Abbreviation	Description
1.	WhiteI	Eve White 1st measurement
2.	WhitII	Eve White 2nd measurement
3.	BlackI	Eve Black 1st measurement
4.	BlacII	Eve Black 2nd measurement
5.	JaneI	Jane 1st measurement
6.	JaneII	Jane 2nd measurement

Data arrangement

A three-way data array X = (x(i,j,k)) has the following form

                        |-----|i=1
                   |-----|    |i=2
              |-----|    |    |..
              |     |    |    |..
              |     |    |____|i=I=15    k=K=6
              |     |____|            k=2
              |_____|              k=1
            j=1,.,J=10

The actual data file has the following form:

          j=1,.,J=10
            |-----|i=1
            |     |i=2
            |     |..     k=1
            |     |..
            |_____|i=I=15
            |-----|i=1
            |     |i=2
            |     |..     k=2
            |     |..
            |_____|i=I=15
            |-----|i=1
            |     |i=2
            |     |..     k=6
            |     |..
            |_____|i=I=15

Thus the first mode (i) is nested in the third mode (k) and there are 15 (Concepts) times 6 (Personalities) rows and 10 (Scales) columns.

Data handling

Preprocessing

Semantic differenctial scales are multiway rating data. However, because they are bipolar scales their orientations are abitrary and one can therefore not sum the scores of each concept across all scales. This means that the only scaling allowed is for each scale-personaly combination. For details see Kroonenberg (2008). Applied multiway data analysis. Hoboken NJ: Wiley (Chapters 6 and 14).

Permissions

These data have been published in Osgood & Luria (1954) and are therefore in the public domain. The more so because the copyright has run out and the electronic rights were not claimed at the time by the publishers. However, please quote the Osgood & Luria paper mentioned above. This website need not be cited when using these data in a publication, but it would be nice if you did.
