Selective Attention & Inhibition

Color Stroop

Report the colour the word is printed in, not what the word says. Trains the inhibition step that comes before encoding.

Science: Stroop (1935). Incongruent trials force you to suppress the automatic reading response — the same control process that prevents you from being distracted while learning a name.

Associative Memory

Face-Name Challenge

Study faces with visual hooks, then recall their names. Trains name-face binding with elaborative encoding.

Science: The Baker/baker paradox (McWeeny et al., 1987). Visual hooks create dual-coding advantage (Paivio, 1971).
Working Memory

Digit Span

Forward first, then backward. Backward span is harder because it requires holding and rearranging the digits — the central-executive part of working memory.

Science: Wechsler digit span (1939, current in WAIS-IV). Forward + backward together measure storage + manipulation (Baddeley & Hitch, 1974). Adult average ≈ 7 forward and 5 backward.

Visuospatial Working Memory

Corsi Block-Tapping

Watch the cells light up in sequence, then tap them in the same order. 4×4 grid, 600 ms pacing — the standardised protocol.

Science: Corsi (1972) / Milner (1971); 4×4 grid and 600 ms pacing per Kessels et al. (2000) norms. Measures the visuospatial sketchpad (Baddeley & Hitch, 1974). Adult mean span ≈ 5.

Click the squares in the same order they lit up.

Semantic Memory

Verbal Fluency

List as many words as you can in 60 seconds for a given topic. Builds category fluency and word retrieval speed.

Science: Category fluency task (Benton & Hamsher, 1976). Sensitive to semantic network integrity (Hodges & Patterson, 1995).
