Popis: Although visual search studies have primarily focused on search behavior, concealment behavior is also important in the real world. However, previous studies in this regard are limited in that their findings about search and concealment strategies are restricted to the spatial (two-dimensional) domain. Thus, this study evaluated strategies during three-dimensional and temporal (i.e., spatiotemporal) search and concealment to determine whether participants would indicate where they would hide or find a target in a temporal sequence of items. The items were stacked in an upward (Experiments 1-3) or downward (Experiment 4) direction and three factors were manipulated: scenario (hide vs. seek), partner type (friend vs. foe), and oddball (unique item in the sequence; present vs. absent). Participants in both the hide and seek scenarios frequently selected the oddball for friends but not foes, which suggests that they applied common strategies because the oddball automatically attracts attention and can be readily discovered by friends. Additionally, a principle unique to the spatiotemporal domain was revealed, i.e., when the oddball was absent, participants in both scenarios frequently selected the topmost item of the stacked layer for friends, regardless of temporal order, whereas they selected the first item in the sequence for foes, regardless of the stacked direction. These principles were not affected by visual masking or number of items in the sequence. Taken together, these results suggest that finding and hiding positions in the spatiotemporal domain rely on the presence of salient items and physical accessibility or temporal remoteness, according to partner type.
