title: Rule based and information integration category learning

description: The following dataset includes sessions from rats and humans learning and
 generalizing to Rule-based and Information Integration categories. Here,
 category exemplars are Gabor patches, which are circular stimuli that
 contain black and white gratings. Across exemplars, these gratings can
 change in their spatial frequency and orientation. For Rule-based tasks,
 only one stimulus dimension (i.e., spatial frequency or orientation) is
 category-relevant, and the other dimension varies randomly. For
 Information Integration tasks, both stimulus dimensions (i.e., spatial
 frequency and orientation) are category-relevant. On each learning trial,
 participants are presented with a category exemplar and must decide its
 category membership. Feedback guides learning. Rats are trained using a
 touchscreen apparatus, whereas humans are trained using a desktop
 computer.

 Additional details -Condition: RBF and RBO
 refer to the two rule-based tasks (RBF: spatial frequency is the relevant
 dimension; RBO: orientation is the relevant dimension).<br>
 -Condition: IIP and IIN refer to the two information integration tasks
 (IIP: RBF distributions are rotated 45 degrees. Thus, distributions have a
 positive slope; IIN: RBF distributions are rotated -45 degrees, and the
 distributions have a negative slope). -Frequency and
 Orientation refer to the physical stimulus values of each exemplar (and
 each range from 0 to 100). -In the trial sequence, the
 rat initiates each trial by pressing a star stimulus at the center of the
 touchscreen.  For each trial, RT and the 'x' and y'
 coordinates of this touch are provided (STAR_RT, STARX, STARY)
 -After a touch of the star, an exemplar is presented at the
 center of the screen (the cue phase), and the rat must touch this cue
 three times for each trial and for each touch of the cue- RT, x and y
 coordinates are provide (CUERT_1 ...,  CUEX_1 ..., CUEY_1 ...)
 -After three touches of the cue, report key appear on sides of
 the screen. The rat must touch either key (CHOICERT, CHOICEX,
 CHOICEY). -For correct responses, a white box appears.
 One touch of the white box delivers a food pellet (REWARDRT, REWARDX,
 REWARDY) -Rats were given training sessions (each
 containing 80 trials) until a learning criterion was met (75% accuracy in
 both categories on 2 consecutive sessions). Then, 5 testing sessions were
 given.   Trial Information:

 -Condition: RB refers to the rule-based task. II refers to the
 information integration task. -Frequency and
 Orientation refer to the physical stimulus values of each exemplar (and
 each range from 0 to 100). -In the trial sequence, the
 participant initiates each trial by pressing the spacebar
 (STARTRT) -Then, an exemplar is presented at the center
 of the screen, and the participant decides its category membership by
 pressing either 'q' or 'p' on the keyboard
 (CHOICERT) -Participants were given two blocks (with 80
 trials each) of training trials. Then, participants were given four blocks
 (each 80 trials) of testing trials.
