theory

• Luria (neuropsych model): sequence processing; simultaneous processing, learning and planning ability

• CHC: short term memory (Gsm); visual spatial processing (Gv); long term storage and retrieval (Glr); fluid reasoning (Gf); crystallized ability (Gc)

reliability

outstanding

MPI = .96

FCI = .97

NVI = .94

validity

satisfactory criterion

factor analysis

Sattler and Dumont

every subtest except for Conceptual Thinking has a loading of .30 or higher on more than one factor

18 subtests → 5 core

• Sequential / Gsm Scale

• Simultaneous / Gv Scale

• Leaning / Glr Scale

• Planning / Gf Scale

• Knowledge / Gc Scale

Sequential / Gsm Scale

measures ability to hold info in immediate memory and then use it within a few seconds

Simultaneous / Gv Scale

interpret/organize visually perceived stimuli and generate hypothesis

Leaning / Glr Scale

learn/store new/previously acquired info and then fluently retrieve the info

Planning / Gf Scale

ability to solve novel tasks by forming/recognizing concepts; identifying/perceiving relationships; drawing information; reorganizing information and tranforming info

Knowledge / Gc Scale

measures depth/breadth of acquired knowledge

interpretation

level 1: focuses on the global scale scores

the FCI will provide the most comprehensive estimate of the child’s level of intellectual ability

level 2: focuses on the specific scale indexes

level 3: focuses on interpreting differences involving subtests and specific scales

level 4: focuses on qualitative analysis

strengths

• 3 global scales

• dual theoretical foundation

• specific scales

• multiple scores

• adequate reliability and validity

limitations

• limited standardization

• lack of test-retest

• limited construct validity

• floor and ceiling effects

• complex admin and scoring guidelines
