In both Pavlovian conditioning and human causal judgment, competition between cues is well known to occur when multiple cues are presented in compound and followed by an outcome. More questionable is the occurrence of competition between outcomes when a single cue is followed by multiple outcomes presented in compound. In the experiment reported here, we demonstrated blocking (a type of stimulu...

The translation vectors of the convenient unit cell, e.g. the cube edges of the fcc structure (which is not primitive) are used for the coordinate axes. The plane shown intercepts at 3, 2, 2 on the axes. As, by definition, these three points are not co-linear, therefore they can adequately define the plane. As we shall see later, the reciprocal of these numbers are more useful. First, reciproca...
