Multiple Completions Primed by Occlusion Patterns

Multiple completions primed by occlusion patterns.

There is a strong tendency to complete a partly occluded shape. Two types of pattern completion, global and local, are frequently reported. By means of the primed-matching paradigm, it has previously been shown that global completions are prevalent for stimuli in which regularity is abundantly present. In our study the primed-matching paradigm is applied to such stimuli in order to find out whe...

Completions of P-matrix patterns

A list of positions in an n × n real matrix (a pattern) is said to have P-completion if every partial P-matrix that specifies exactly these positions can be completed to a P-matrix. We extend work of Johnson and Kroschel [JK] by proving a larger class of patterns has Pcompletion, including any 4 × 4 pattern with eight or fewer off-diagonal positions. We also show that any pattern whose digraph ...

Competing global and local completions in visual occlusion.

In visual occlusion 2 amodal-completion tendencies occur frequently. One tendency leads toward the simplest completed shape (a global completion) and the other to a shape for which the completion itself is as simple as possible (a local completion). Two experimental paradigms were used to test the strengths of these completion tendencies: a drawing task and a simultaneous matching task. The exp...
