The Lexical Decision Task (LDT) measures the speed and accuracy of word recognition — a core index of semantic memory organization and implicit associative processes. Participants discriminate real words from pronounceable non-words under time pressure, and systematic variations in response time across word categories reveal the architecture of associative networks.
What This Report Shows
The sample report demonstrates Implicitify AI's LDT output: overall accuracy and reaction time, word vs. non-word discrimination performance, derived metrics (inverse efficiency, d-prime sensitivity), and comparisons to English Lexicon Project (ELP) norms. All scores are reported on a standardized scale (M=100, SD=15) with percentile ranks and qualitative classifications.
Implicit Assessment Value
Unlike self-report questionnaires, the LDT captures implicit cognitive processes that operate outside conscious awareness. Primed LDT variants reveal associative biases — the degree to which certain concepts are automatically linked in memory. This makes the task particularly valuable for assessing schema activation, emotional priming, and implicit attitudes that self-report measures cannot access.
