Document Summary

Notation system: describes the number of variables and levels used in the study: e. g. , 2x3 factorial. 2 independent variables: one with 2 levels, one with 3 levels. 3 independent variables: 2, 4, & 4 levels. How well they can focus on a target & ignore distractors (visual or auditory) Generalized 2x2 factorial matrix: independent variable #1 factor a, levels a1 & A2: independent variable #2 factor b, levels b1 & B2: combine to form four conditions a1b1, etc. Each condition = one cell of the matrix. 2 potential effects in the selective attention study: target type, distractor type. Two independent variables, main effects for both: sex of rater. Males rating females > females rating males. Perhaps females have higher standards than males: time period (more significant to this study) Highest ratings at 12:00, then 10:30, then 9:00. The later it is, the higher the rating. Closing time effect that affected both genders, regardless of their gender.
