【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。

【畢業演講】Individual Differences and Neural Bases of Technology-Mediated Verbal and Nonverbal Communication

心理學系 — Thu, 28 May 2026 02:00:56 +0000

Technology-mediated communication has become increasingly central to everyday social interaction, yet its psychological and neural consequences remain incompletely understood. When people communicate through video conferencing systems or interact with AI agents, the social conditions of communication are altered: the interlocutor may be nonhuman, nonverbal cues may be reduced, and the emotional context may become ambiguous. This study examined how such technological mediation influences communicative experience, cognitive performance, and neural processing, with particular attention to individual differences.

Two complementary experiments were conducted. The first used an fMRI agent-interaction task to compare brain responses during interactions with human partners and chatbots, and examined whether subjective ratings of fluency, sociality, and human-likeness were associated with distinct neural activation patterns. The second investigated video conferencing, testing how camera use, emotional climate, and personality traits jointly predicted memory retention and attentional performance.

Results suggested that chatbots interaction elicited stronger engagement of attention and cognitive control networks, indicating that communicating with AI may require greater cognitive resources than human interaction. In video meetings, camera use itself did not significantly affect memory performance. Instead, personality-related factors were more predictive: higher agreeableness was associated with poorer memory, and extraverts showed reduced recall in emotionally neutral contexts. Overall, the findings suggest that the effects of technology-mediated communication depend more on individual characteristics and socio-emotional context than on technological format alone.

【畢業演講】從專注到幸福：心理機制、個人實踐、人際影響力的探討

心理學系 — Thu, 21 May 2026 05:48:43 +0000

在數位科技高度滲透的當代，社交媒體的持續干擾使人們長期處於分心狀態；與此同時，個體內在紛擾的思緒亦不斷將注意力從當下抽離。這種普遍的分心狀態不僅削弱個體的認知功能，更對人們的幸福感造成深遠的負面影響。如何形塑當下的專注力與幸福感，已成為學界與實務界共同關注的核心議題。本次分享以「專注當下」與「幸福感」為核心構念，從內在機制、個人實踐與人際影響力三個層次展開探討。第一部分從機制層次切入，探究外在動機如何削弱專注與幸福感之間的正向關係，並檢視自我慈悲特質在個體分心時的關鍵緩衝作用。第二部分從個人實踐層次出發，檢驗日常正念訓練與自然環境介入如何有效提升日常生活中的專注力與整體幸福感。第三部分將視角延伸至人際影響層次，探討正念特質較高的個體如何透過情緒、語言及非語言行為促進人際互動品質，並探討賦予正念角色的聊天機器人如何促進個體的感恩行為。本次分享不僅從理論層次中揭示動機對專注與幸福感的影響關係，亦在實踐層次為提升自身與他人福祉提供具體啟示。
