Previous research has shown that damage to the left temporal pole (LTP) is associated with impaired retrieval of words for unique entities, including names of famous people and landmarks. However, it is not known whether retrieving names for famous melodies is associated with the LTP. The aim of this study was to investigate the hypothesis that damage to the LTP would be associated with impaired naming of famous musical melodies.
A Melody Naming Test was administered to patients with LTP damage, brain damaged comparison (BDC) patients, and normal comparison participants (NC). The test included various well-known melodies (e.g., "Pop Goes the Weasel"). After hearing each melody, participants were asked to rate their familiarity with the melody and identify it by name.
LTP patients named significantly fewer melodies than BDC and NC participants. Recognition of melodies did not differ significantly between groups.
The findings suggest that LTP supports retrieval of names for famous melodies. More broadly, these results extend support for the theoretical notion that LTP is important for retrieving proper names for unique concepts, irrespectively of stimulus modality or category.
先前的研究表明，左颞极（LTP）损伤与独特实体词（包括名人姓名和地标名称）的检索受损有关。然而，目前尚不清楚检索著名旋律的名称是否与 LTP 有关。本研究旨在调查 LTP 损伤与检索著名音乐旋律的能力受损相关的假设。
对 LTP 损伤患者、脑损伤对照组（BDC）患者和正常对照组（NC）参与者进行旋律命名测试。测试包括各种著名的旋律（例如，“ Pop Goes the Weasel”）。听到每个旋律后，参与者被要求对旋律的熟悉程度进行评分，并通过名称识别旋律。
LTP 患者命名的旋律明显少于 BDC 和 NC 参与者。组间对旋律的识别没有显著差异。
这些发现表明 LTP 支持检索著名旋律的名称。更广泛地说，这些结果扩展了理论观点的支持，即 LTP 对于检索独特概念的专有名称很重要，而与刺激方式或类别无关。
