Assessments

Score bands added by Stat Sheet are response-scale descriptions, not population norms. IPIP-NEO-120 and CAT-Q source materials supply no normative bands or diagnostic cutoffs for these displays. TwIVI bands describe similarity to value portraits, not a ranking of value priorities. O*NET interest results show activity ratings.

Mini-IPIP

Donnellan, M. B., Oswald, F. L., Baird, B. M., & Lucas, R. E. (2006). The Mini-IPIP scales: Tiny-yet-effective measures of the Big Five factors of personality. Psychological Assessment, 18(2), 192–203. Mini-IPIP scoring key. Public-domain IPIP items. The response-scale bands shown here are app descriptions, not population norms.

IPIP-NEO-120

International Personality Item Pool (IPIP), Oregon Research Institute; Johnson, J. A. (2014), Measuring thirty facets of the Five Factor Model with a 120-item public domain inventory: Development of the IPIP-NEO-120, Journal of Research in Personality, 51, 78–89. The source supplies no norms or bands; Stat Sheet’s response-scale bands are app descriptions.

TwIVI

Sandy, C. J., Gosling, S. D., Schwartz, S. H., & Koelkebeck, T. (2017), The Development and Validation of Brief and Ultrabrief Measures of Values, Journal of Personality Assessment, 99(2), 208–219.

Extras: IQ Range

IQ Range tasks are app-generated or app-written activities, not licensed copies of published test items and not a clinical IQ test. Results describe performance on these activities. A paradigm citation describes an influence on a task format; it does not imply permission to reproduce published items.

Patterns uses generated matrix rules and tiles, with Raven’s progressive-matrices paradigm as a reference: Raven (1941), Progressive Matrices.
Spatial rotation uses generated connected shapes and app-specific turns or reflections, with mental-rotation research as a reference: Shepard & Metzler (1971).
Sequence memory uses app-generated forward and reverse sequences on a 4×4 grid, with block-span research as a reference: Corsi (1972).
Word knowledge uses original app-written word-pair and meaning items, with analogy research as a reference: Sternberg (1977).
Visual search uses generated symbol lines and app-generated timing, with visual-search research as a reference: Treisman & Gelade (1980).
The account-backed patterns check uses an app-specific adaptive 2-up/1-down procedure, with adaptive psychophysical methods as a reference: Levitt (1971), Transformed up-down methods in psychoacoustics.

Extras: puzzles

Match Shift uses app-generated seven-segment matchstick boards. Traffic Exit uses generated sliding-block boards; no third-party level corpus is included. Sudoku uses app-generated unique-solution fixtures. Puzzle layouts and levels are not licensed copies of third-party collections.
