感知依赖于语境。例如，条的感知方向取决于它周围有方向的条的存在。背景效应也被证明适用于更复杂的判断，比如面部吸引力或表情，尽管目前还不清楚这些背景面部效应是如何取决于目标面部周围的面部类型的。为了检验这一点，我们测量了目标面部在周围不同年龄的面部存在下的感知年龄（一种可量化的测量）。使用标准化护照照片的独特数据库，参与者被要求估计目标人脸的年龄，这些人脸要么单独观看，要么被两个不同身份的侧面脸包围。侧脸与目标脸的年龄差分别为±5岁、±10岁、±15岁、±20岁。我们发现，当一张目标脸被年轻的面孔包围时，它会比单独看时显得更年轻，而当它被年长的面孔包围时，它会比单独看时显得更老。令人惊讶的是，我们发现侧卫对目标感知年龄的影响程度是不对称的，年轻的侧卫比年长的侧卫有更大的影响，这一结果可能反映了参与者自己的年龄偏见，因为所有参与者都很年轻。这一结果与性别或种族无关，与平均结果一致。
Perception is context dependent. For example, the perceived orientation of a bar changes depending on the presence of oriented bars around it. Contextual effects have also been demonstrated for more complex judgements, such as facial attractiveness or expression, although it remains unclear how these contextual facial effects depend on the types of faces surrounding the target face. To examine this, we measured the perceived age (a quantifiable measure) of a target face in the presence of differently aged faces in the surround. Using a unique database of standardized passport photos, participants were asked to estimate the age of a target face which was viewed either on its own or surrounded by two different identity flanker faces. The flanker faces were either both younger or both older than the target face, with different age offsets between flankers and targets of ±5, ±10, ±15, ±20 years. We find that when a target face is surrounded by younger faces, it systematically appears younger than when viewed on its own, and when it is surrounded by older faces, it systematically appears older than when viewed on its own. Surprisingly, we find that the magnitude of the flanker effects on perceived age of the target is asymmetric with younger flankers having a greater influence than older flankers, a result that may reflect the participants' own-age bias, since all participants were young. This result holds irrespective of gender or race of the faces and is consistent with averaging.
