Gifted Issues Discussion homepage Forums Identification, Testing & Assessment Got our WISC results- processing issues?

Hi Everyone- My DS6 took the WISC-V and I had a question about the results. Specifically, that his processing speed seems considerably lower than his other scores.
Verbal Comprehension (VCI)-136
Visual Spatial (VSI)-147
Fluid Reasoning (FRI)-144
Working Memory (WMI)*-127
Processing Speed (PSI)-103
Full Scale (FSIQ)*-141
General Ability Index (GAI)-147

His examiner wrote in the report about the processing speed:
"Processing Speed requires rapid and efficient information processing, visual discrimination, focused attention, and the ability to perform under conditions of pressure and high arousal (i.e. when being timed). DS scored in the Average range on the WISC-V Processing Speed Index (PSI) (SS=103; 58%). Personal weaknesses in processing speed can be indicative of weakness in executive functioning and/or attentional control.
DS scored in the Average range on the Symbol Search subtest (ScS=9), which required him to detect symbols within an array. DS worked quickly, but made three, likely careless, errors while rushing to beat the clock. This suggests that DS may sometimes sacrifice accuracy for speed. DS scored at the highest end of the Average range on the Coding subtest (ScS=12). The Coding subtest required DS to encode symbols matched with numbers, and then to write the corresponding symbol under each prompt number. DS worked accurately and at an age appropriate pace. He appeared to memorize the symbols as he worked."

And in the summary, she stated, "DS Working Memory was inconsistent and indicative of a mild personal weakness which may indicate mild weaknesses in executive functioning and/or attentional control. DS demonstrated stronger visual working memory than auditory working memory. However, his overall working memory is still well-developed compared to same age peers, ranging from High Average to Very Superior. Similarly, though DS personally slower processing speed and occasional carelessness under time pressure may be indicative of executive functioning weakness, it may simply indicate that DS works at an age appropriate pace. He earned an Average WISC-V Processing Speed score. On other tasks which required DS to complete items in a specific amount of time, his speed was variable. He often worked quite quickly, though when items were extremely challenging, he sometimes required additional time to demonstrate his full knowledge and ability. DS was attentive and engaged. His activity level was appropriate for a six year old. Thus, at this time, this evaluator’s concerns about DS attention and executive functioning are minor."

So my question is, we have not noticed any indications of ADHD or executive function problems at home or school. What might this look like? People have always commented on what a surprising long attention span he has. He comes home from first grade, gets a snack, unpacks and does his homework without any prompting. I don't need to repeat multi-step directions. Any other ideas? Anything else stand out as significant? Thank you so much!
