Task | Examined variables |
|
Memory updating-attention focus switching | |
|
Auditory stimuli | Overall accuracy (across all 30 trials) |
| Accuracy—high-frequency trials; low-frequency trials |
| Accuracy—high tones; low tones |
| Mean switch cost accuracy (difference in accuracy between high and low frequency trials) |
| Mean switch RT; mean non-switch RT |
| Mean switch cost RT (difference in RT between switch and non-switch presentations) |
Visual stimuli | Overall accuracy (across all 30 trials) |
| Accuracy—high-frequency trials; low-frequency trials |
| Accuracy—big squares; small squares |
| Mean switch cost accuracy (difference in accuracy between high and low frequency trials) |
| Mean switch RT; Mean non-switch RT |
| Mean switch cost RT (difference in RT between switch and non-switch presentations) |
Variables used in the model | Composite of scores of overall accuracy from the two tasks |
| Composite of scores of mean switch RT from two tasks |
| Composite of scores of switch cost accuracy from two tasks |
| Composite of scores of switch cost RT from two tasks |
|
Sustained attention | |
|
| Hit rate (child hits/45-total possible hits) |
Gordon—auditory stimuli | False alarm rate (child false alarms/495-total possible false alarms) |
| prime (difference between scores of hit and false alarm rates) |
| Hit rate (child hits/45-total possible hits) |
Gordon—visual stimuli | False alarm rate (child false alarms/495-total possible false alarms) |
| prime (difference between scores of hit and false alarm rates) |
Variable used in the model | Composite prime from auditory and visual prime indices |
|
Verbal working memory | |
|
Listening span | Total trials with accurate digit recall; Sentence comprehension accuracy and processing time |
Counting span | Total trials with accurate count recall |
Variable used in the model | Composite scores from recall scores on listening and counting span |
