Perception and Communication

I think the perception and communication section was interesting but some concepts I would like some more explanation.  When it came to the interpretation section I became a little confused.  Attributions have 4 different parts there is locus, internal and external.  I understood the fact that we can understand why something happens either internally or externally but I didn’t understand what the locus part was.  The next part is stability which explains actions as the result of stable and unstable factors.  Specificity explains the behavior in terms of specific or global implications.  This part confused me a bit because to me it seemed like stability and specificity were the same.  The last concept is responsibility in which if we think the person can control the behavior they are considered responsible.  However, if it is beyond their control they may not be responsible.  Some of these concepts were hard to understand when it comes to the specific examples.
