Abstract Early home musical environments can significantly impact sensory, cognitive, and socioemotional development. While longitudinal studies may be resource-intensive, retrospective reports are a relatively quick and inexpensive way to examine associations between early home musical environments and adult outcomes. We present the Music@Home–Retrospective scale, derived partly from the Music@Home–Preschool scale (Politimou et al., 2018), to retrospectively assess the childhood home musical environment. In two studies (totaln = 578), we conducted an exploratory factor analysis (Study 1) and confirmatory factor analysis (Study 2) on items, including many adapted from the Music@Home–Preschool scale. This revealed a 20-item solution with five subscales. Items retained for three subscales (Caregiver Beliefs, Caregiver Initiation of Singing, Child Engagement with Music) load identically to three in the Music@Home-–Preschool Scale. We also identified two additional dimensions of the childhood home musical environment. The Attitude Toward Childhood Home Musical Environment subscale captures participants’ current adult attitudes toward their childhood home musical environment, and the Social Listening Contexts subscale indexes the degree to which participants listened to music at home with others (i.e., friends, siblings, and caregivers). Music@Home–Retrospective scores were related to adult self-reports of musicality, performance on a melodic perception task, and self-reports of well-being, demonstrating utility in measuring the early home music environment as captured through this scale. The Music@Home–Retrospective scale is freely available to enable future investigations exploring how the early home musical environment relates to adult cognition, affect, and behavior. 

Recent findings in Alzheimer’s disease research has suggested that light entrainment in the form of gamma-band (40 Hz) stimulation can ameliorate Alzheimer’s-associated pathology and improve cognition. Here we report feasibility of a music-based intervention that is coupled with light entrainment in the gamma band, as well as a control intervention that pairs podcast listening with lights tuned to delta but not gamma band frequencies. We compare qualitative data from participant-maintained logbooks (diaries) and researcher notes using Natural Language Processing (NLP) methods, specifically word count and sentiment analysis, and show that both music-listening and podcast-listening participants spent a similar amount of time engaging with intervention and, on average, described positively valenced experiences. Results suggest the importance of naturalistic data obtained from diary studies as a snapshot of ongoing interventions. 

Music is often considered an important domain for creativity. Traditional studies of musical creativity have examined musical improvisation using jazz as a model. While this approach has yielded many valuable insights about creativity’s cognitive and neural mechanisms, it has limited the study sample to those with the means to engage in improvisation within one specific Western style. Here, we introduce a novel tool for assessing musical creativity in the broader sample of individuals with no specialized training. In two experiments (n = 165) we show that this sequencer can be used in people with minimal training to generate a database of sequences composed at the Bohlen-Pierce scale and to evaluate them for creativity. Results show that creativity ratings are predicted by length of melodies, number of distinct pitches used, and information content of pitch intervals. Results also show some external validity with existing creativity tasks. We advocate the use of this sequencer in creativity research, as it provides a theoretically motivated, rigorous tool to examine the iterative process of producing and evaluating musical creativity.

Music listening can evoke a range of extra-musical thoughts, from colors and smells to autobiographical memories and fictional stories. We investigated music-evoked thoughts as an overarching category, to examine how the music’s genre and emotional expression, as well as familiarity with the style and liking of individual excerpts, predicted the occurrence, type, novelty, and valence of thoughts. We selected 24 unfamiliar, instrumental music excerpts evenly distributed across three genres (classical, electronic, pop/rock) and two levels of expressed valence (positive, negative) and arousal (high, low). UK participants (N = 148, Mage = 28.68) heard these 30-second excerpts, described any thoughts that had occurred while listening, and rated various features of the thoughts and music. The occurrence and type of thoughts varied across genres, with classical and electronic excerpts evoking more thoughts than pop/rock excerpts. Classical excerpts evoked more music-related thoughts, fictional stories, and media-related memories, while electronic music evoked more abstract visual images than the other genres. Positively valenced music and more liked excerpts elicited more positive thought content. Liking and familiarity with a style also increased thought occurrence, while familiarity decreased the novelty of thought content. These findings have key implications for understanding how music impacts imagination and creative processes. 

The speech-to-song illusion is a perceptual transformation in which a spoken phrase initially heard as speech begins to sound like song across repetitions. In two experiments, we tested whether phrase-specific learning and memory processes engaged by repetition contribute to the illusion. In Experiment 1, participants heard 16 phrases across two conditions. In both conditions, participants heard eight repetitions of each phrase and rated their experience after each repetition using a 10-point scale from “sounds like speech” to “sounds like song.” The conditions differed in whether the repetitions were heard consecutively or interleaved such that participants were exposed to other phrases between each repetition. The illusion was strongest when exposures to phrases happened consecutively, but phrases were still rated as more song-like after interleaved exposures. In Experiment 2, participants heard eight consecutive repetitions of each of eight phrases. Seven days later, participants were exposed to eight consecutive repetitions of the eight phrases heard previously as well as eight novel phrases. The illusion was preserved across a delay of one week: familiar phrases were rated as more song-like in session two than novel phrases. The results provide evidence for the role of rapid phrase-specific learning and long-term memory in the speech-to-song illusion. 

Groove, or the pleasurable urge to move to music, offers unique insight into the relationship between emotion and action. The predictive coding of music model posits that groove is linked to predictions of music formed over time, with stimuli of moderate complexity rated as most pleasurable and likely to engender movement. At the same time, listeners vary in the pleasure they derive from music listening: individuals with musical anhedonia report reduced pleasure during music listening despite no impairments in music perception and no general anhedonia. Little is known about musical anhedonics’ subjective experience of groove. Here we examined the relationship between groove and music reward sensitivity. Participants (n = 287) heard drum-breaks that varied in perceived complexity, and rated each for pleasure and wanting to move. Musical anhedonics (n = 13) had significantly lower ratings compared to controls (n = 13) matched on music perception abilities and general anhedonia. However, both groups demonstrated the classic inverted-U relationship between ratings of pleasure & move and stimulus complexity, with ratings peaking for intermediately complex stimuli. Across our entire sample, pleasure ratings were most strongly related with music reward sensitivity for highly complex stimuli (i.e., there was an interaction between music reward sensitivity and stimulus complexity). Finally, the sensorimotor subscale of music reward was uniquely associated with move, but not pleasure, ratings above and beyond the five other dimensions of musical reward. Results highlight the multidimensional nature of reward sensitivity and suggest that pleasure and wanting to move are driven by overlapping but separable mechanisms. 

This article argues that the capacity of music to reliably cue both autobiographical memories and fictional imaginings can be leveraged to better understand the relationship and interdependence between memory and imagination more generally. The multiple levels involved in musical engagement provide a rich forum for investigating how emotional, semantic, and contextual associations with musical cues influence both memories and imaginings. Moreover, musical excerpts are extended in time and can influence the trajectory of a memory or imagining dynamically as it develops, allowing for a more precise manipulation of the implied semantic space. Because music’s uses and contextual associations are culturally constrained, and culture can be shared, autobiographical memories and fictional imaginings cued by music can show surprising similarities among individuals from the same culture. This article surveys the research on music-evoked autobiographical memories and music-evoked fictional imaginings, proposing a framework for bringing these separate strands of work together to shed light on larger questions about shared underlying mechanisms. 

Pleasure in music has been linked to predictive coding of melodic and rhythmic patterns, subserved by connectivity between regions in the brain's auditory and reward networks. Specific musical anhedonics derive little pleasure from music and have altered auditory-reward connectivity, but no difficulties with music perception abilities and no generalized physical anhedonia. Recent research suggests that specific musical anhedonics experience pleasure in nonmusical sounds, suggesting that the implicated brain pathways may be specific to music reward. However, this work used sounds with clear real-world sources (e.g., babies laughing, crowds cheering), so positive hedonic responses could be based on the referents of these sounds rather than the sounds themselves. We presented specific musical anhedonics and matched controls with isolated short pleasing and displeasing synthesized sounds of varying timbres with no clear real-world referents. While the two groups found displeasing sounds equally displeasing, the musical anhedonics gave substantially lower pleasure ratings to the pleasing sounds, indicating that their sonic anhedonia is not limited to musical rhythms and melodies. Furthermore, across a large sample of participants, mean pleasure ratings for pleasing synthesized sounds predicted significant and similar variance in six dimensions of musical reward considered to be relatively independent, suggesting that pleasure in sonic timbres play a role in eliciting reward-related responses to music. We replicate the earlier findings of preserved pleasure ratings for semantically referential sounds in musical anhedonics and find that pleasure ratings of semantic referents, when presented without sounds, correlated with ratings for the sounds themselves. This association was stronger in musical anhedonics than in controls, suggesting the use of semantic knowledge as a compensatory mechanism for affective sound processing. Our results indicate that specific musical anhedonia is not entirely specific to melodic and rhythmic processing, and suggest that timbre merits further research as a source of pleasure in music. 

Human imagination is generative and creative yet deeply rooted in culture and familiarity. Recent studies have quantified the effects of culture on stories that are imagined during music listening, but the music used in previous work was always drawn from a tradition familiar to participants from at least one of the cultures. Here we report the first study of imagined stories to music written in a musical system that is novel to participants from each culture, thus allowing for a direct comparison of narratives prompted by the same set of excerpts that is comparably unfamiliar to both groups. Music composed in the Bohlen–Pierce scale was presented to participants from two geographically defined cultures: Boston, United States and Beijing, China. We also examined how individual differences, such as in musicality and sensitivity to musical reward, might affect narrative engagement and semantic content of the imagined stories as measured by tools from natural language processing. Results showed that semantic spaces of music-evoked imaginings differed between Boston and Beijing cohorts. While both cultures were similarly engaged by the story response task, differences emerged in the semantic content of the imagined stories. Boston participants who reported being more absorbed by music wrote more unconventional stories, whereas Beijing participants who reported more emotional responses to music wrote more conventional stories. These results reveal the roles of culture and individual differences in modes of narrative engagement and imagination during music listening.
