ABSTRACT

Masturbation is a common human behaviour. Compared to other unimanual behaviours it has unique properties, including increased sexual and emotional arousal, and privacy. Self-reported hand preference for masturbation was examined in 104 left-handed and 103 right-handed women, and 100 left-handed and 99 right-handed men. Handedness (modified Edinburgh Handedness Inventory, EHI), footedness, eyedness, and cheek kissing preferences were also measured. Seventy nine percent used their dominant hand (always/usually) for masturbation, but left-handers (71.5%) were less consistently lateralized to use their dominant hand than right-handers (86.5%). Hand preference for masturbation correlated more strongly with handedness (EHI), than with footedness, eyedness, or cheek preference. There was no difference in masturbation frequency between left- and right-handers, but men masturbated more frequently than women, and more women (75%) than men (33%) masturbated with sex aids. For kissing the preferred cheek of an emotionally close person from the viewer’s perspective, left-handers showed a left-cheek preference, and right-handers a weaker right-cheek preference. The results suggest that hemispheric asymmetries in emotion do not influence hand preference for masturbation but may promote a leftward shift in cheek kissing. In all, masturbation is lateralized in a similar way to other manual motor behaviours in left-handed and right-handed men and women.

摘要

手淫是一种常见的人类行为。与其他单手行为相比，它具有独特的特性，包括增加性和情感唤起以及隐私。在 104 名左撇子和 103 名右撇子女性以及 100 名左撇子和 99 名右撇子男性中检查了自述的手淫偏好。还测量了惯用手（修改后的爱丁堡惯用手量表，EHI）、脚力、眼睛和脸颊亲吻偏好。79% 的人（总是/通常）使用惯用手进行自慰，但左撇子（71.5%）与右撇子（86.5%）相比，左撇子（71.5%）不太一致地使用惯用手。自慰的手偏好与惯用手（EHI）相关，而不是与脚、眼睛或脸颊偏好相关。左撇子和右撇子的手淫频率没有差异，但男性比女性更频繁地手淫，女性（75%）比男性（33%）更多地使用性工具自慰。从观众的角度来看，在亲吻情感亲近的人偏爱的脸颊时，左撇子表现出对左脸颊的偏好，而右撇子则对右脸颊的偏好较弱。结果表明，情绪中的半球不对称不会影响手对手淫的偏好，但可能会促进脸颊亲吻的左移。总之，手淫的侧向化方式与左撇子和右撇子男性和女性的其他手动运动行为类似。从观众的角度来看，在亲吻情感亲近的人偏爱的脸颊时，左撇子表现出对左脸颊的偏好，而右撇子则对右脸颊的偏好较弱。结果表明，情绪中的半球不对称不会影响手对手淫的偏好，但可能会促进脸颊亲吻的左移。总之，手淫的侧向化方式与左撇子和右撇子男性和女性的其他手动运动行为类似。从观众的角度来看，在亲吻情感亲近的人偏爱的脸颊时，左撇子表现出对左脸颊的偏好，而右撇子则对右脸颊的偏好较弱。结果表明，情绪中的半球不对称不会影响手对手淫的偏好，但可能会促进脸颊亲吻的左移。总之，手淫的侧向化方式与左撇子和右撇子男性和女性的其他手动运动行为类似。
