生殖是科学的基础,也是最近讨论的问题。我们报告的挑战,概念复制时,采用不同的读出措施,以针对相同的理论结构,特别是那些需要探测的反应。这是解决的恐惧条件反射范式,情感学习的原型,在三个实验组(Ntotal= 57)。我们证明,包括惊吓探针(95分贝突发的白色噪音),以引起惊吓反射延迟收购的恐惧,反映了皮肤电导反应和间歇性的恐惧评级。恐惧等级的纳入反过来并没有显着影响恐惧的获取。因此,实验设计中的细微差异,例如纳入单一额外结局指标,可能会对研究结果和解释产生重大影响。因此,在组间比较中常见的小效应可能特别容易受到这种影响,这对采用略有不同的实验设计的研究结果的重复具有强烈的影响。
Reproducibility is fundamental to science and a recent matter of discussion. We report challenges for conceptual replications when employing different readout measures to target the same theoretical construct, particularly those requiring probed reactions. This was addressed in a fear conditioning paradigm, a prototype of emotional learning, in three experimental groups (Ntotal= 57). We demonstrate that the inclusion of startle probes (95 dB burst of white noise) to elicit a startle reflex delays the acquisition of fear as reflected by skin conductance responses and intermittent fear ratings. The inclusion of fear ratings in turn did not significantly affect fear acquisition. Hence, subtle differences in experimental design, such as the inclusion of a single additional outcome measure, may substantially impact on study results and interpretations. Thus, small effects, as are common in between‐group comparisons, may be particularly susceptible to this, which has strong implications for the replication of findings across studies employing slightly different experimental designs.
