20 th January 2011 Psych 178 – Lecture 6 The Person as a Machine – Physical Sciences Lewin’s Theory How is the environment perceived by an individual? Behaviour is a function of who the person is and the perceived environment. The person is described with two constructs: o Dynamic: force, action, energy. Tension. Valence – if there is an appropriate object to fulfill the need, then it have a positive valence. A valence may or may not exist but given a positive valence, there must be a need. Force – if there is a valenced object, there is a force field that the person is within and the forces act upon the person in the direction of the object. They push the person towards the valenced object. What are the determinants of force? What are the mathematic values of desires? o The degree of tension – how much does the person want it? o Properties of goal object o Distance from the goal object – the closer you are, the greater the force. Not symmetrical. You overestimate the time you take to go somewhere and underestimate the time it takes to get home. Psychological movement.
