先前对重复不熟悉的刺激的影响的实验研究表明，仅仅是暴露就会产生吸引力（例如，Zajonc，1968）。另一方面，与自然发生的刺激（如名字、音乐或风景）相关的研究表明，也存在过度扩展效应：偏好功能最初确实会随着熟悉程度的增加而增加，但随后会达到一个转折点并减弱。该研究（N = 72）在实验环境中证明了这种倒U型关系。刺激是合成的无意义的讲话，允许精确控制曝光时间和刺激间隔。证明这种效应的关键因素可能是（1）包含大量的重复，（2）以均匀的序列阻止每个刺激的重复，而不与其他或多或少的频率刺激穿插。
Previous experimental investigation of the effects of repeating an unfamiliar stimulus suggests that mere exposure breeds attraction (e.g., Zajonc, 1968). On the other hand, correlational work with naturally occurring stimuli such as names, music, or landscapes suggests that there is also an overexposure effect: the preference function does rise with familiarity at first but then reaches a turning point and diminishes. The study (N = 72) demonstrates this inverted-U relationship in an experimental setting. The stimuli were synthetic nonsense speech, permitting exact control of exposure durations and interstimulus intervals. The critical factors for demonstrating the effect are probably (1) the inclusion of a large number of repetitions, and (2) blocked repetition of each stimulus in a homogeneous sequence not interspersed with other more or less frequent stimuli.
