摘要

目的本研究探讨了奖赏反应期间中枢多巴胺反应的外周标志物--射血前期（PEP）奖赏反应性与性受害和反复性受害之间的关系。结果我们发现，在两组（即重复性伤害与他人伤害）比较中，经历过重复性伤害的人与只经历过一次伤害或没有经历过伤害的人相比，对奖赏的前射血期缩短程度较低、反复与其他）比较。结论与类似的研究一致，重复性受害者的 PEP 缩短较少，这可能表明他们在生理上对奖赏不敏感，可能会寻求感觉或风险来提高中枢多巴胺的活性。由于样本量（n = 44）的限制，研究结果应结合新的探索性研究的背景。

Pre-ejection period (PEP) in reward task and recurring victimization: A pilot study

Objectives

This study examines the relationship between pre-ejection period (PEP) reward reactivity, a peripheral marker for central dopamine reactivity during reward responding, and sexual victimization and recurring sexual victimization.

Methods

Electrocardiogram and impedance cardiography were recorded during a simple number-matching reward task to calculate PEP reward reactivity among 44 female college students.

Results

We found that those who experienced recurring sexual victimization had less PEP shortening to reward than those who experienced a single victimization and no victimization in a two-group (i.e., recurring vs. others) comparison. However, when examining these three groups, the differences in scores were not statistically significant.

Conclusions

In line with similar research, less PEP shortening among recurring sexual victims may suggest that they are insensitive physiologically to reward and may seek sensation or risk to upregulate their central dopamine activity. Findings should be contextualized within the lens of novel exploratory research, limited by sample size (n = 44).

期刊介绍： The Journal of Experimental Criminology focuses on high quality experimental and quasi-experimental research in the advancement of criminological theory and/or the development of evidence based crime and justice policy. The journal is also committed to the advancement of the science of systematic reviews and experimental methods in criminology and criminal justice. The journal seeks empirical papers on experimental and quasi-experimental studies, systematic reviews on substantive criminological and criminal justice issues, and methodological papers on experimentation and systematic review. The journal encourages submissions from scholars in the broad array of scientific disciplines that are concerned with criminology as well as crime and justice problems.
