Manhattan Cognitive Assessment — Full Profile
Composite Cognitive Index (CCI) · 4 domain indices · 8 subtests · Provisional norms
✓ Performance Validity: Established
Performance validity indices are within acceptable limits on both the immediate (FCRM-1) and delayed (FCRM-2) forced-choice recognition trials. There is no indication of inadequate effort. All cognitive scores are considered valid and interpretable.
VLI
Verbal & Language Index
T = 63 · 90th %ile
Superior
| Subtest | Raw | T-score (90% CI) | %ile | Range |
|---|---|---|---|---|
|
Lexical Decision
The Lexical Decision Task measures millisecond-precision lexical-semantic access — how rapidly stored verbal representations are retrieved from long-term memory. Item-level reaction times are z-scored against English Lexicon Project norms (Balota et al., 2007, N = 816). The measure loads on both verbal/language and semantic-memory dimensions.

Verbal Analogies
Verbal analogical reasoning assesses the ability to identify semantic relationships between concepts, tapping the interface of crystallized and fluid intelligence (Gc–Gf).

2/2 | 64 56–72 |
92nd | Superior |
|
General Knowledge
Semantic factual knowledge reflects the breadth of long-term knowledge acquisition and is among the most g-loaded and neurologically resilient cognitive measures, widely used as a premorbid estimate.

3/3 | 70 62–78 |
98th | Very Superior |
NVI
Nonverbal / Visuospatial Index
T = 57 · 76th %ile

| Subtest | Raw | T-score (90% CI) | %ile | Range |

Abstract Pattern Reasoning
Abstract matrix reasoning measures fluid intelligence (Gf) — the capacity to identify rules in novel visual patterns independent of prior knowledge. This is the most culture-reduced measure of general cognitive ability.
|
2/3 | 50 42–58 |
50th | Average |
|
Mental Rotation
Mental rotation (Shepard & Metzler, 1971) measures visuospatial processing — the capacity to mentally manipulate objects in space. Response latency scales linearly with angular disparity between stimuli.

2/2 | 64 56–72 |

Memory & Learning Index
T = 57 · 76th %ile
High Average
| Subtest | Raw | T-score (90% CI) | %ile | Range |

Immediate Recognition
FCRM-1 is the immediate trial of a two-alternative forced-choice recognition memory paradigm. In addition to indexing encoding efficiency, it provides a primary performance validity index — performance meaningfully below chance indicates inadequate effort (Slick, Sherman & Iverson, 1999).
|
4/5 | 56 48–64 |
73rd | Average |
|
Delayed Recognition
FCRM-2 is the delayed retention trial of the forced-choice recognition memory paradigm, administered after a filled interval. It indexes hippocampal-dependent consolidation and provides a secondary performance validity measure (Slick, Sherman & Iverson, 1999). Comparison with FCRM-1 dissociates encoding failure from consolidation deficit.

Color Stroop
Color-word interference (Stroop, 1935) measures inhibitory control and selective attention under response conflict — a hallmark executive function measure with established frontal lobe sensitivity.

Research and educational use only. The MaCA is a brief, self-administered screening instrument developed by Dr. Daniel J. Winarick. The norms are provisional and based on a convenience sample. This report is not a clinical evaluation, a neuropsychological assessment, or a diagnosis. Scores can be influenced by fatigue, anxiety, distraction, internet latency, and other factors unrelated to cognitive ability. Do not use this result for clinical, occupational, or legal decisions without a formal evaluation by a qualified professional.
