Connotations
In both varieties, the behavioral sense carries a slightly clinical or diagnostic connotation when used about adults, but is common in general discourse about children.
Frequency
Slightly more frequent in American English in the behavioral sense, due to broader cultural penetration of psychological terminology.

Common Pitfalls
Translation Traps (for Russian speakers)
- Not equivalent to 'разыгрывать' in all contexts. 'Act out' implies a performance of something pre-existing (a script, feeling). 'Act out' (behavioral) is close to 'плохо вести себя из-за внутренних проблем'. Avoid confusing with 'act up' (which is more about malfunctioning or minor misbehaviour).
Common Mistakes
- Using 'act out' when 'act up' is meant (for malfunctions or petty misbehaviour). *'My computer is acting out.' (Incorrect) vs. 'My computer is acting up.' (Correct). Confusing it with 'act on' (to take action based on something).
