+====== Mental Grouping ======
+===== Meaning 1 =====
+==== Alternative Terms ====
+/*i.e. alternative names meaning the same thing*/
+==== Definition ====
+**Mental grouping** is an activity which is sometimes necessary in order to understand code. You do it when you try to find out what a group of statements does.
+==== Description ====
+If you read code several statements may belong together and have a combined purpose. If these lines aren't already grouped syntactically by having a method with a fitting name, the reader of the code will inevitably create this missing abstraction while reading the code. This is necessary for understanding.
+On the other hand the necessity to do mental grouping is a deficiency of the code. If the grouping would manifest as a syntactic structure like a method, the code would be easier to understand.
+The same holds for bigger structures, so any concept which is needed for understanding but not physically represented as a variable, a method, a class, a package, etc. requires the reader to do mental grouping each time the code is read.
+==== Examples ====
+==== Alternative Definitions ====
+/*i.e. slightly different definitions for basically the same thing*/
+==== See Also ====
+  * The contrary activity is [[mental inlining]]
+  * [[principles:Single Level of Abstraction]] is about avoiding mental grouping
