1 ASL Stories Test

2 ASL Stories Test Structure Similar to WMS “logical memory” subtest Two stories conceived in ASL Train story (~ 1’ 30”), 43 scoreable elements Kidnap story (~ 2’ 07”), 63 scoreable elements (WMS-R logical memory stories have 25)

3 Video: Instructions and Stories 1. Train Story 2. Kidnap Story

4 Examples of Scoreable Elements THREE-WEEK-AGO WITH #DOG 2 “*(2H) SCL:V “jumping”*th”, PLAY SIT-IN WHEELCHAIR (2H) DCL:f “holes in eyes… …and nose areas” WITH NUMBER 4-5-3 (downwards) PRINCIPAL (nod)

5 Method Same healthy participants as SPAT study N = 41 Mean age 27.6 (s.d., 4.7, range 18-34) 54% male, 46% female Mean PIQ 104 (s.d. 12.8, range 75-128) Administered ASL Stories, SPAT, PIQ

6 Method (cont.) First story learning trail, immediate recall Second story learning trial, immediate recall ~20” delay period (non-verbal tasks) Delayed recall (both stories) Three-step cueing quiz, 20 elements (each) Freely recalled, recalled w/ question, 3 choices Recall videos scored by 3 ASL-fluent assists.

7 Inter-Rater Reliability (ICC) Story/ConditionICC* Train Immediate Recall Correct Total0.941 Train Delayed Recall Correct Total0.888 Kidnap Immediate Recall Correct Total0.771 Kidnap Delayed Recall Correct Total0.808 These are good intra-class correlation figures, suggesting reliable scoring results regardless of (sign-fluent) rater Train story scoring was slightly more reliable probably due to fewer elements (43 vs. 63)

8 ASL Stories Norms (averaged over three raters) Story/ConditionMean (S.D.)Percent Correct Train Immediate Correct Overall Mean24.8 (8.77)57.8 (.20) Train Delayed Correct Overall Mean27.0 (8.04)62.9 (.19) Kidnap Immediate Correct Overall Mean41.5 (9.93)65.9 (.16) Kidnap Delayed Correct Overall Mean42.7 (10.4)67.8 (.16) Train story = 34 scoreable elements Kidnap story = 64 scoreable elements Train vs. Kidnap immediate recall percentages significantly different (p =.0013) Train vs. Kidnap delayed recall percentages significantly different (p =.0235) Despite 20 fewer elements, Train story is significantly harder

12 Next Steps Review, complete data analyses Draft manuscript for publication Prepare DVDs of stories and instructions

13 Future Research Ideas Why is Kidnap story easier? Why were so many elements necessary? Can it differentiate a clinical sample? Correlation with non-verbal tests? Correlation with “hearing” verbal tests? How much ASL fluency is needed? Alternate administration methods?
