Description
Check a memory-probe position under zero/one-based indexing.
Cognitive research records can encode stimuli, response timing, probability assumptions and observation support. Local differences and caller-defined tolerance labels do not establish perceptual validity, a cognitive mechanism, statistical equivalence or a clinical assessment.
Check a memory-probe position under zero/one-based indexing.
When to use this tool
Use Working Memory Probe Position Budget when checking a supplied cognitive-task timing, stimulus, probability or evidence convention.
How to use the tool and how it works
- Enter setSize, probePosition, zeroBased. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read index, valid, remainingItems. Inspect valid before interpreting the associated values.
Check a memory-probe position under zero/one-based indexing. Require nonnegative whole setSize/probePosition; index = probePosition-(zeroBased ? 0 : 1), valid tests [0,setSize), remainingItems = size-index-1.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| setSize | Set Size | Required. Safe integer; minimum 0. |
| probePosition | Probe Position | Required. Safe integer; minimum 0. |
| zeroBased | Zero Based | Required. Boolean. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| index | Position under the explicit indexing convention; inspect any missing-value sentinel. | Required. Safe integer. |
| valid | Whether this local input/result condition holds; inspect the limitations before treating it as full validation. | Required. Boolean. |
| remainingItems | setSize-index-1 even when valid=false; an invalid position is not clamped. | Required. Safe integer. |

}Limitations and assumptions
- Invalid positions return an algebraic index/remainder rather than an input error; inspect valid before interpreting them.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use a validated study design, calibrated measurements and appropriate statistical/professional interpretation for cognitive or health conclusions.
