Project Versions¶
All versions of the project were created in Psychopy. The code for all experiment versions is on github.
Note
Versions 1 and 2 were made with the Builder interface. Version 3 was written in plain Python using the Psychopy 3 toolbox.
The current iterations of the project include:
v1¶
Description¶
- 1,2,3 multipliers
Goal¶
- Disambuguate atribute weights from attribute evaluation
- Test whether value and weighting affect subject attention
v2¶
Description¶
- Additional multipliers (0.1, 0.5, 1, 2, 3, 10)
Goal¶
- Test response to fractional weights
- Calculate subjects’ weighting curve to wider range of weights
v3.0.1¶
Description¶
- Both multipliers onscreen simultaneously (0.1, 0.33, 0.5, 1, 2, 3, 10)
Goal¶
- Test whether subjects bias their first/total fixation to the higher multiplier
v3.0.2¶
Description¶
- Accuracy incentive
- Both multipliers onscreen simultaneously (0.1, 0.33, 0.5, 1, 2, 3, 10)
Goal¶
Test whether subjects try harder with an accuracy incentive, rather than a cumulative payoff
- This avoids the most difficult trials having the lowest value/cost
v3.1.0¶
Description¶
- Time pressure (low)
- Accuracy incentive
- Both multipliers onscreen simultaneously (0.1, 0.33, 0.5, 1, 2, 3, 10)
Goal¶
- Test whether time pressure increases the likelihood of biasing first fixation toward the higher weighted stimulus
v3.1.1¶
Description¶
- Time pressure (low/high/no)
- Accuracy incentive
- Both multipliers onscreen simultaneously (0.1, 0.5, 1, 2, 3, 10)
Goal¶
- Test whether time pressure increases the likelihood of biasing first fixation toward the higher weighted stimulus under three conditions.
