Lecture 33

Question 1

What was the hypothesis for Kelso’s experiment?

Answer 1

Reaction time for planning congruent tasks is shorter than RT for incongruent tasks

Question 2

Describe Franz’s experimental set up

Answer 2

• Three conditions
  1. Basic bi-manual task = the circles are separate
  2. Perceptual manipulation = bars join the circles together
  3. Conceptual manipulation = using the basic-bimanual task with a display with two options
• In unified trials displays says phrases that hint to the hands being connected
• In separate trials the displays will say phrases that hint to the hands being separate

Question 3

Describe the hypotheses in Franz’s experiment

Answer 3

Levels that try to connect the hands as performing one task on in-congruent tasks will have equal reaction time to congruent tasks

Question 4

What were Franz’s findings?

Answer 4

• How we think about the tasks (either as two separate or one singular) influences how we plan and execute the tasks
• Conceptually unified instructions eliminate sensorimotor interference effects when related to incongruent distances
