![]() ![]() ![]() I don't think you've presented any data that would suggest concerns with your intrinsic working memory. Takeaways: nothing about this faux WAIS digit span contradicts any of your other data on working memory. Letter-number-sequencing is similar to DSS, but slightly harder, since there are two layers of sequencing needed (average more like 5). The average adult reaches a ceiling at 7 digits forward, and fewer than that backward (5) and sequenced (6), which actually means that they get both seven-digit items incorrect. You did not reach a personal ceiling on digits forward or digits backward, and, in fact, ran into the hard ceiling of the test.Ģ. If so, there are two important points, without even getting into what your normative score would be had this been a real WAIS:ġ. Is this an accurate representation of your recent digit span exercise?īoth items correct at all sets up to six digits I think you may be misunderstanding the way the norms for these work. I would always forget what I just learned, and I would have to go reread the material over and over to have it stick to my memory, which is a waste of time. I think that I would ace all of the other sections of the WAIS-IV with perfect scores in all of the subtests, but not in working memory. Basically at the 100th percentile, yet I can't score that high on the WAIS-IV digit span tests. I took the human benchmark memory tests a couple of months ago and got 100 percentile on the sequence memory (score of 67), number memory (score of 20 with the use of mnemonics), verbal memory (556), chimp test (31), visual memory (20). I also did terribly on letter-number sequencing stopping at 6 letters/numbers. I think that my lack of academic success and respect from others is the result of having a poor memory. The episodic buffer: A new component of working memory? Trends in Cognitive Sciences, 4(11), 417-423.I recently did a mock WAIS-IV digit span test on, and I was able to memorize up to 9 digits missing one at 7 digits and one at 9 digits, 8 digits backwards missing one at 6 digits and one at 8 digits, 8 digits ordered missing both at 8 digits.

These results have potential implications for optimizing the current cognitive training on working memory.Ĭontralateral delay activity event-related potential filtering efficiency randomized controlled trial working memory span. Backward span training also improved interference control based on the ERP data (CDA_filtering efficiency) to a greater extent than did forward span training and no intervention, but the three groups did not differ in terms of behavioral indices of interference control. Compared to no intervention, both forward and backward span trainings led to significantly greater improvement in working memory maintenance, based on indices from both behavioral (Kmax) and ERP data (CDA_2T0D and CDA_4T0D). Behavioral data were collected from two additional tasks: a multi-object version of the change detection task, and a suppress task. Event-related potential (ERP) signals were recorded at the pre-, mid-, and post-tests while the subjects were performing a distractor version of the change detection task, which included three conditions (2 targets and 0 distractor 4 targets and 0 distractor and 2 targets and 2 distractors ). Based on data from a randomized controlled trial, this study (N = 60 healthy college students) tested the effects of backward span training, forward span training, and no intervention. Both forward and backward working memory span tasks have been used in cognitive training, but no study has been conducted to test whether the two types of trainings are equally effective. ![]()
