Two types of hypotheses interest psychologists: causal hypotheses and associative hypotheses. The conclusions that can be reached from studies examining these hypotheses and the methods that should be used to investigate them differ. Causal hypotheses examine how a manipulation affects future events, whereas associative hypotheses examine how often certain events co-occur. In general, experimental methods with random allocation are well suited for addressing causal hypotheses, whereas random sampling is an asset when examining associative hypotheses. These hypotheses are discussed primarily with reference to 4 topics within eyewitness testimony research: the own-race bias, emotion and memory, event duration estimation, and system variables in lineups. Some other examples in forensic psychology are provided to illustrate difference between causal and associative hypotheses. Copyright 2006 by the American Psycholgical Association.
