What
is theory and what is it not?
Well,
let's start with the former. Theory for scientific studies is
something that involves explanation of an action, construct etc.,
predictions about this and apart from this it should also be
testable. In a general sense theory, in it's core, is something we
humans construct to describe and explain our world,
to enchance our own understanding of this world we live in. These
criterias for something being a theory is often supplemended by the
ability to give predictions of future actions, events and so on. Is
'this-and this' a theory then? Does it explain why, give predictions
and is it testable? Then yes.

Theory
is not anything in the following types [2]:
- Theory is not references, references just relate to theories and does not explain. An example of this is 'this gives that'. This reference does not explain the logic of why 'this gives that' as an theory would have done.
- Data is not theory. Data gives a description of empirical patterns involved but it does not explain why theese are involved.Yes, data is an important part of theorizing but it is not the whole of a theory.
- From type three we derive that variables or constructs are not theory. As stated before theese kinds of parts are important part of theorizing, but because they do not, in themselves, give an explanation of why they exist or how they are connected they do not count as theory.
- Diagrams and figures are not theory. They may be helpful in visualisating parts of explanations but they do not explain theese parts.
- Hypotheses and/or predictions are not theory. They are basically statements about what we expect should happen and do not explain why this is expected.
Selected
paper and it's major theories
For
this theme I've chosen the paper Virtual
Interpersonal Touch: Expressing and Recognizing Emotions
Though Haptic Devices
by authors Jeremy N. Bailenson et al (2007). The paper brings up a
number of theories that is central to the paper, basically we can
divide them into three major theories.
Facial
expressions
During
the course of experiencing an emotion facial muscles move. These
movements are the effect of a number of biological changes causing
different facial muscles to work. (Type 4)
Voice
Different
emotions result in different usage of our own voice. Every emotion
has it's own range in pitch, rhythm, amplitude and duration causing
us to interpret the emotion correctly. (Type 4)
Touch
Touch in
it's general sense is a signal used to increase trust. Through touch
a person can interpret urgency, sincerity, significance etc. For
instance a handshake can transmit different kinds of emotions
depending on for example, dryness, firmness of grip, temperature etc.
(Type 4)
Benefits
and limitations
The
benefits of using these theories is that they create a fundamental
understanding of the basic emotional systems in human interaction.
This wide range of basic theory includes the most usable interaction
types when decodings different signals for specific emotions.
The
limitations of these theories is that, for example, the theory about
use of touch is a rather unexplored when it comes to interaction
between humans, person-through computer-to-person. The theories used
are quite many and could in extension split the researchers and
readers focus when it comes to making conclusions about their study.

I think the theories taken up in the paper you have chosen is interesting, mainly because they are very hard to describe and we humans often doesn't think about how they work. There is much going on with our expressions,thereof things we don't think about. It's interesting with explanations for why we sometimes instantly react like we do, without knowing or thinking about why we do it. Here is a utube vid about something similar, that maybe could go under facial expressions; http://www.youtube.com/watch?feature=player_embedded&v=-qDi7IbYGVY
