Description of data fields in by-subject files Note: all timeouts, as well as one erroneous trial per subject per session, are excluded from these by-subject summaries sub: subject identifier antifirst: logical indicating whether subject was exposed to the anti-spirantization language during their first session antihitperc: hit percentage for target-right trials in the anti-spirantization condition antifaperc: false alarm percentage for target-left trials in the anti-spirantization condition spirhitperc: hit percentage for target-right trials in the spirantization condition spirfaperc: false alarm percentage for target-left trials in the spirantization condition antidp: sensitivity (d') to the word-nonword distinction in the anti-spirantization condition spirdp: sensitivity (d') to the word-nonword distinction in the spirantization condition antipc: accuracy (percent correct) in the anti-spirantization condition spirpc: accuracy (percent correct) in the anti-spirantization condition totpc: pooled accuracy (percent correct) across the two conditions age: in years nwr: standardized score on non-word repetition task from CTOPP-2 recsent: standardized score on recalling sentences task from CELF-5 iq: standardized 2-subtest IQ score from WASI-II digmem: standardized score on memory for digits task from CTOPP-2 **************** Description of data fields in by-trial files sub: subject identifier sess2: logical indicating whether trial is from 2nd session anti: logical indicating whether trial comes from anti-spirantization condition word1, word2: identifiers for the first and second (left and right) words presented during each 2AFC trial. Lower number is target, higher is foil. targsec: logical indicating whether target is presented second (right) respsec: logical indicating whether subject responded 'second' (right) rt: reaction time in milliseconds. 4000 indicates timeout (there is one erroneous trial with 5200 timeout; we don't know why). ctr: trial number (first coded as 0th trial) within session, centered (around 17.5). correct: logical indicating whether response is correct; 'NA' indicates no response. odd: logical indicating whether trial number within session is odd (for split-half reliability test).
