Phoenix Wright Ace Attorney helps kids practice and improve the following skills:

Focus: Getting started and then maintaining attention and effort to tasks. 

The player needs to use their focusing skills in the Phoenix Wright games because, as visual novels, there is a great deal of reading. The information you get from characters and from the evidence you find can all help you put the pieces together about the case you need to defend so if the player is not focused, they may miss crucial information that causes them to lose their trial. For players who struggle with focusing, information is able to be repeated as many times as necessary so going back and re-reading for clarification or to highlight important points is possible and can help with practicing focus in small doses. 

Working Memory: Recalling and retaining information in our minds while working.

During each trial, the player will hear testimony from various witnesses. The player will then have to decide whether or not this testimony is truthful and if they have evidence to prove their assertion. While the player is reading the testimony, they need to be able to recall statements they have previously heard, as well as remember what evidence they have in their possession in order to make a successful objection. Players who struggle with working memory may find that it is difficult to determine which statements the witnesses make are true and which are false. In order to practice working memory, players can reread the text as many times as they need to and check their evidence file frequently until they have built up enough confidence to remember what they have while they are hearing the testimony.
