Most of us, drivers and observers alike, would tend to attribute hisactions to "dispositional" factors: he's a terrible driver, he likes to scare people on the road, etc. We tend tooverlook the possible "situational" factors that may be contributing to his recklessness: he's rushing to thehospital, he just spilled his own chicken nuggets and temporarily lost control of the car, etc. Psychologistscall this tendency to attribute (often incorrectly) others' actions to dispositional factors rather than tosituational factors as the fundamental attribution error.We're interested in seeing if there's a difference in inclination to commit the fundamental attribution erroramong groups that differ in level of psychology training. We choose three groups of adults to participate instudy: adults who have no psychology training, adults who have a psychology degree but who are notpracticing psychologists, and adults who are practicing psychologists. We show each participant a videotapeon which a scenario similar to the one described above was enacted. Then we ask the participants questionabout why the characters in the enactment behaved as they did. We are examining the variables level ofpsychology training ("no psych training", "psych degree, but not a psychologist", and "psychologist") andtype(s) of attributions emphasized ("mostly situational", "mixed", and "mostly dispositional").Suppose that our data are those summarized in the contingency table below. Each cell of the table contaithree numbers: the first number is the observed cell frequency (fo), the second number is the expectedfrequency (fp) under the assumption that the two variables level of psychology training and type(s) ofattributions emphasized are not associated, and the third number is the following value.E(Observed cell frequencyExpected cell frequency )"SEExpected cell frequencyThe numbers labeled "Total" are totals for observed frequency.
