Need for Closure Urgency & Permanence (1) Urgency, or the desire to come to an answer quickly. Urgency leads to a tendency to quickly seize upon the first information that provides an answer. (2) Permanence, or the tendency to stick to an answer. Permanence leads to a tendency to freeze upon the answer or decision once it is reached. Thus, need for closure may lead individuals to focus only on the initial information provided and to be less likely to change their answers when confronted with new evidence.
True Need for Surveillance Imagery • To reconstruct a memory, the eyewitness draws upon several sources of information, only one being his or her actual recollection. To fill in gaps in memory, the eyewitness relies upon his or her expectation, attitudes, prejudices, bias, and prior knowledge. Furthermore, information supplied to an eyewitness after a crime • (i.e., post-event information) by the police, prosecutor, other eyewitnesses, media, etc., can alter an eyewitness’s memory of the crime.
