The theory also suggests that we may associate a person with positive feelings due to the even in which they meet; this is called classical conditioning. This form of conditioning involves pairing a neutral stimulus with an unconditioned stimulus to create a conditioned response, for example being at a party (NS) and feeling happy (UCR), then meeting a person (UCS) and associating this stimuli (now CS)with the happy feelings to create a CR of happiness whenever in their presence and we want to be with the person that makes us most happy, thus forming a relationship.
An issue raised surrounding the RNS theory is that it fails to consider free will. It suggests that without rewards a relationship will not form however evidence from modern relationships argues otherwise, for example a rewards and satisfaction is given in one night stands, yet no relationship is formed, plus no association can be made through cyber relationships because the couple have not met, yet a relationship still manages to form. This evidence goes against the theory suggesting that other factors such as similarity, opportunity and our own choices play a role in relationship formation thus
