A Quarter of a Century of Sponge Biodiversity and Functioning in the Spermonde Archipelago (Indonesia): Impacts of Eutrophication and Environmental Change.

海洋研究所 — Wed, 24 Jun 2026 01:54:58 +0000

Nicole de Voogd (https://www.naturalis.nl/en/science/researchers/nicole-voogd) is a world-leading sponge expert, bringing taxonomy, biodiversity, and reef ecology together to reveal the hidden importance of sponges in tropical marine ecosystems. Her talk will explore how decades of research in Indonesia have reshaped our understanding of sponge communities and their responses to eutrophication and environmental change.

【博二生演講】Music-to-Lexical Tone Transfer in Infancy: Effects of Distributional Learning Under Varying Acoustic Complexity

心理學系 — Fri, 05 Jun 2026 07:27:05 +0000

Lexical tone perception is essential for preverbal infants learning a tonal language to encode pitch variation as a lexically contrastive dimension for constructing the lexical meanings of syllables. The perception of native and non-native lexical tones undergoes rapid developmental changes between 6 and 12 months of age; however, the learning mechanisms underpinning these changes remain an open question. While distributional statistical learning supports lexical tone acquisition in infants learning non-tonal languages, and music-to-lexical tone transfer is well-documented in non-tonal language adults, it remains unclear whether early musical exposure can combine with statistical learning to facilitate learning native lexical tones in preverbal infants. Furthermore, whether the acoustic complexity of musical melodies moderates this perceptual learning has yet to be determined. Experiment 1 exposed Mandarin-learning 7- and 11-month-olds (n = 63) to a violin continuum, distributed in either a unimodal or bimodal pattern, and subsequently tested the infants on distinguishing the Mandarin Tone 2 vs. Tone 3 contrast. For both infant age groups, both distributional learning conditions induced significant and equivalent perceptual improvements, indicating that passive musical exposure is sufficient to facilitate tonal development. Experiment 2 exposed Mandarin-learning infants (n = 75) to musical melodies with a mixed-instrument continuum combining violin and erhu to increase acoustic complexity in the distributional learning context. Under high acoustic complexity, results revealed that the music exposure gain was marginally moderated by input distribution, showing an advantage of bimodal distribution over unimodal distribution. Furthermore, 7-month-olds exhibited bimodal distributional learning advantages across both single- and mixed-instrument conditions, whereas 11-month-olds improved comparably across both conditions regardless of distributional inputs. These findings demonstrate that music-to-lexical tone transfer learning is an effective mechanism for infants learning a tonal language, but this cross-domain facilitation is constrained by both the music input distribution pattern and developmental timing.

【畢業演講】身體的自我保護機制–多維度痛覺在自傷行為中的表現

心理學系 — Thu, 04 Jun 2026 06:18:26 +0000

身體的內在感受性(interoception awareness)是幫助個體維持內在穩定以達到自我保護的機制，具有多維度的特質，廣義上痛覺(pain)屬於內在感受性的一種，是個體發生傷害時的重要訊息，然而，自我傷害行為卻突破痛覺的防線，個體主動造成身體的傷害甚至威脅生命，這可能與自傷行為者的痛覺鈍化有關，此外，非自殺自傷行為的功能可能也有影響。過往研究中，自傷行為的受試者間痛覺鈍化的現象使用「直接製造疼痛」的方式進行研究的結果最為一致，然而，此方法有倫理考量與天花板的限制，同時，臨床上也無法應用，此外，討痛覺對於未來自傷風險的影響，以及痛覺與自傷行為功能之間的關係的研究都非常少。

為探討這些問題，本研究以內在感受性多維度的角度，編製了痛覺多維度評估清單(Dimensional inventory of pain assessment, DIPA)，以346位受試者進行研究(200名網路樣本，146名臨床樣本)。結果顯示，控制了憂鬱與激躁後特定性痛覺敏感與特定性痛覺不耐受可區分一年內有自殺意念與自傷行為的受試者；以羅吉斯回歸建立受試者發生自傷行為的預測模型中，曾經發生非自殺自傷行為以及六個月內最高的自殺意念強度是最重要的預測因子，而憂鬱與痛覺則發揮統計聯合控制的效果提高了預測力；在自傷行為的功能中，DIPA中三個量尺與非自殺自傷行為的社會正增強功能有關，一般性痛覺耐受與自動正增強有關，而自動負增強則有需要細分其內涵。

總結來說，多維度評估清單可以看到痛覺在自傷行為者間鈍化的現象，不同維度的痛覺評估也與非自殺自傷行為正增強需求有關，然而自動負增強的功能則需要更多的研究。
