Intervention: C8 - Stimulus Variety (SV)
Description: The base task for SV is the PT condition. However, SV employ 20 trial mini-blocks of different SFs (.75, 1.5, 3, 6, 12, 24 cpd) and locations (45°, 135°, 225°, 315° - i.e., more locations than PT, but not the full set tested in the transfer battery) with separate staircases for each SF and location. Orientations will also be drawn from a larger set (22.5°, 45°, 67.5° - for which participants respond clockwise and 112.5°, 135°, 157.5° - for which participants respond counter-clockwise) and will vary on a trial-by-trial basis. This design holds-out 4 locations and 2 orientations to address transfer.

Intervention: C8a - Complex Features (CF)
Description: This is the same as C8, however we will use band-pass filtered stimuli similar to what has been done by a number of groups including Hussein et al.

Intervention: C9 - Exogenous Attention Training (ExAT)
Description: Stimuli will be presented in a similar manner as in PT. However, in ExAT, a 100% valid cue, a small black dot - 48ms duration with an 96ms SOA prior to stimulus onset - will appear above the target location on each trial.

Description: Stimuli will be presented in a similar manner as in PT. However, in EnAT, a 100% valid cue (letter UL, LR; standing for upper left and lower right, respectively) - 150ms duration with an 500ms SOA prior to stimulus onset - will appear at the fixation point.

Intervention: C11 - Multisensory Facilitation (MF)
Description: MF utilizes the same basic task structure as in ExEAT, however, rather than a visual cue, an auditory cue will be used (50ms, 1000hz tone with sound location determined by convolving sound with generic head-related transfer function, kemar large ears.
