Reflection is often used as part of software testing, such as for the runtime creation/instantiation of mock objects. Reflection is also a key strategy for metaprogramming. In some object-oriented programming languages such as C# and Java, reflection can be used to bypass member accessibility rules. For C#-properties this can be achieved by ...
Programming languages and computing platforms that typically support reflective programming (reflection) include dynamically typed languages such as Smalltalk, Perl, PHP, Python, VBScript, and JavaScript. Also the .NET languages are supported and the Maude system of rewriting logic.
Reflection is common in many dynamic languages, and typically involves analysis of the types and metadata of generic or polymorphic data. It can, however, also include full evaluation and modification of a program's code as data, such as the features that Lisp provides in analyzing S-expressions .
Haxe is a general-purpose programming language supporting object-oriented programming, generic programming, and various functional programming constructs. Features such as iterations, exceptions, and reflective programming (code reflection) are also built-in functions of the language and libraries.
The ability of a programming language to be its own metalanguage allows reflective programming, and is termed reflection. [4] Reflection is a valuable language feature to facilitate metaprogramming. Metaprogramming was popular in the 1970s and 1980s using list processing languages such as Lisp .
In computer science, reification is the process by which an abstract idea about a program is turned into an explicit data model or other object created in a programming language. A computable/addressable object—a resource —is created in a system as a proxy for a non computable/addressable object.

I would think of a programming paradigm as a set of concepts, a set of things which you can or cannot do in a certain language or a certain style of programming. Reflection rather is a one-trick-pony, enabling the programmer to get the identifier of some entity at runtime (or similar concepts) and make a decision upon the result.
