2  Measure the performance efficiency of participants as they engage in map-reading tasks that require the processing of geographic information  To identify the relationships between top-down and bottom- up processes related to searching and recalling geographic information

3  Accuracy and reaction times are frequently used as measures of success (performance efficiency) in cognitive experiments  This study examine three factors that could influence performance: gender, memory, and brain asymmetry

4  Data Gather Steps ◦ Measure second and fourth digits ◦ Bem Sex Role Inventory ◦ Spatial Working Memory Span Test (Computerized version of the Corsi Block Task) ◦ Verbal Working Memory Span Test  Experiment ◦ Participants were randomly presented with state names for the 48 contiguous states of the U.S. and asked to identify each state on an unlabeled map

5 IndependentExplanation 2D/4D RatioRecorded in millimeters GenderFemininity, Masculinity, Undifferentiated, Androgynous Spatial Working Memory Average of highest recalled objects for each round Verbal Working Memory Average of highest recalled letters for each round AreaArea of each state PopulationPopulation of each state DistanceParticipants’ home state to state

6 F = 5.8, P > F = 0.016F = 17.3, P > F = F = 15.5, P > F = 0.000F = 0.6, P > F = 0.446

7  Gender revealed interesting differences  Participants with high spatial AND Verbal scores had better performance  2D/4D ratio had mixed results  Area of the state and distance from home state impacted performance
