Subjects viewed letters and judged whether they were mirror-reversed or not (task LETTER), viewed pictures of a hand and assessed whether it was a right or a left hand (task HAND), and viewed drawings of a person at a table that contained both a weapon and a rose and had to decide whether the weapon was on the right or left side of the table (task SCENE).
DOI: http://dx.doi.org/10.7554/eLife.07902.004 To ensure that behavioural performance (proportion correct) was matched across stimulus types, and that no learning was shown across task runs, we conducted a 3 (task: scenes, faces, size) × 2 (run number: run 1, run 2, run 3) analysis of variance (ANOVA).
In both tasks, the scene was displayed with the target object floating over a "floor"—a flat plane with a cross-hatch pattern textured on it.
The general-purpose representation likely developed for ecologically important tasks like scene perception, but also likely supports understanding of web pages, in part because design develops to make use of existing visual processing architecture in the human visual system.
This is an object detection task like the animal/no-animal task in scene perception studies (Kirchner & Thorpe, 2006; Li et al., 2002; Thorpe et al., 1996).
The monkeys with discrimination learning experience underwent this third stage of pretraining between acquisition of the strategy task and the scene task.
All of this makes the task of scene change recognition that much harder.
Handcrafted image features designed for the task of scene classification are used as the baseline for comparison.
Results were mixed, varying by type of fusion, task, and scene content.
The distractors filtered in the TPJs, however, may include distractors other than task-introduced scene distractors.
