Pitches that Wire Together Fire Together: Scale Degree Associations Across Time Predict Melodic Expectations

The ongoing generation of expectations is fundamental to listeners’ experience of music, but research into types of statistical information that listeners extract from musical melodies has tended to emphasize transition probabilities and n-grams, with limited consideration given to other types of statistical learning that may be relevant. Temporal associations between scale degrees represent a different type of information present in musical melodies that can be learned from musical corpora using expectation networks, a computationally simple method based on activation and decay. Expectation networks infer the expectation of encountering one scale degree followed in the near (but not necessarily immediate) future by another given scale degree, with previous work suggesting that scale degree associations learned by expectation networks better predict listener ratings of pitch similarity than transition probabilities. The current work outlines how these learned scale degree associations can be combined to predict melodic continuations and tests the resulting predictions on a dataset of listener responses to a musical cloze task previously used to compare two other models of melodic expectation, a variable-order Markov model (IDyOM) and Temperley’s music-theoretically motivated model. Under multinomial logistic regression, all three models explain significant unique variance in human melodic expectations, with coefficient estimates highest for expectation networks. These results suggest that generalized scale degree associations informed by both adjacent and non-adjacent relationships between melodic notes influence listeners’ melodic predictions above and beyond n-gram context, highlighting the need to consider a broader range of statistical learning processes that may underlie listeners’ expectations for upcoming musical events.

Comparing Frequency of Listener Responses Between Adolescents with and Without ASD During Conversation

In conversation, the listener plays an active role in conversation success, specifically by providing listener feedback which signals comprehension and interest. Previous work has shown that frequency of feedback positively correlates with conversation success. Because individuals with ASD are known to struggle with various conversational skills, e.g., turn-taking and commenting, this study examines their use of listener feedback by comparing the frequency of feedback produced by 20 adolescents with ASD and 23 neurotypical (NT) adolescents. We coded verbal and nonverbal listener feedback during the time when participants were listening in a semi-structured interview with a research assistant. Results show that ASD participants produced significantly fewer instances of listener feedback than NT adolescents, which likely contributes to difficulties with social interactions.

Reevaluating pragmatic reasoning in language games

The results of a highly influential study that tested the predictions of the Rational Speech Act (RSA) model suggest that (a) listeners use pragmatic reasoning in one-shot web-based referential communication games despite the artificial, highly constrained, and minimally interactive nature of the task, and (b) that RSA accurately captures this behavior. In this work, we reevaluate the contribution of the pragmatic reasoning formalized by RSA in explaining listener behavior by comparing RSA to a baseline literal listener model that is only driven by literal word meaning and the prior probability of referring to an object. Across three experiments we observe only modest evidence of pragmatic behavior in one-shot web-based language games, and only under very limited circumstances. We find that although RSA provides a strong fit to listener responses, it does not perform better than the baseline literal listener model. Our results suggest that while participants playing the role of the Speaker are informative in these one-shot web-based reference games, participants playing the role of the Listener only rarely take this Speaker behavior into account to reason about the intended referent. In addition, we show that RSA’s fit is primarily due to a combination of non-pragmatic factors, perhaps the most surprising of which is that in the majority of conditions that are amenable to pragmatic reasoning, RSA (accurately) predicts that listeners will behave non-pragmatically. This leads us to conclude that RSA’s strong overall correlation with human behavior in one-shot web-based language games does not reflect listener’s pragmatic reasoning about informative speakers.

Memory for musical tones: The impact of tonality and the creation of false memories

Although the relation between tonality and musical memory has been fairly well-studied, less is known regarding the contribution of tonal-schematic expectancies to this relation. Three experiments investigated the influence of tonal expectancies on memory for single tones in a tonal melodic context. In the first experiment, listener responses indicated superior recognition of both expected and unexpected targets in a major tonal context than for moderately expected targets. Importantly, and in support of previous work on false memories, listener responses also revealed a higher false alarm rate for expected than unexpected targets. These results indicate roles for tonal schematic congruency as well as distinctiveness in memory for melodic tones. The second experiment utilized minor melodies, which weakened tonal expectancies since the minor tonality can be represented in three forms simultaneously. Finally, tonal expectancies were abolished entirely in the third experiment through the use of atonal melodies. Accordingly, the expectancy-based results observed in the first experiment were disrupted in the second experiment, and disappeared in the third experiment. These results are discussed in light of schema theory, musical expectancy, and classic memory work on the availability and distinctiveness heuristics.

Affiliation in interpreter-mediated therapeutic talk

The aim of this article is to explore how affiliation (Stivers 2008) with the patient is displayed and interactionally achieved in the context of an interpreter-mediated therapeutic dialogue. More specifically, we focus on the interplay between affiliative listener responses – especially head nods – and gaze in this setting. Interpreter-mediated therapeutic talk is not only a setting that has received very little systematic scrutiny in the literature, but it is also particularly interesting for the study of listener responses. Drawing on the insights from Conversation Analysis, a naturally occurring interpreter-mediated therapeutic session was analysed that had been recorded using mobile eye-tracking technology. This approach allowed for a detailed analysis of the interlocutors’ synchronous gaze behaviour in relation to speech and head nods during the interaction. The results revealed differences in the interpreter’s and the therapist’s affiliative listener responses that were linked to the interactional goals of the encounter and to their social roles. Moreover, we found a strong relationship between mutual gaze and head nods as tokens of affiliation. Thus, these findings provide support for the inclusion of gaze in studies of interpreter-mediated dialogue and, more broadly, in the study of affiliation in social interaction.

Classification of Infant Vocalizations by Untrained Listeners

Purpose To better enable communication among researchers, clinicians, and caregivers, we aimed to assess how untrained listeners classify early infant vocalization types in comparison to terms currently used by researchers and clinicians. Method Listeners were caregivers with no prior formal education in speech and language development. A 1st group of listeners reported on clinician/researcher-classified vowel, squeal, growl, raspberry, whisper, laugh, and cry vocalizations obtained from archived video/audio recordings of 10 infants from 4 through 12 months of age. A list of commonly used terms was generated based on listener responses and the standard research terminology. A 2nd group of listeners was presented with the same vocalizations and asked to select terms from the list that they thought best described the sounds. Results Classifications of the vocalizations by listeners largely overlapped with published categorical descriptors and yielded additional insight into alternate terms commonly used. The biggest discrepancies were found for the vowel category. Conclusion Prior research has shown that caregivers are accurate in identifying canonical babbling, a major prelinguistic vocalization milestone occurring at about 6–7 months of age. This indicates that caregivers are also well attuned to even earlier emerging vocalization types. This supports the value of continuing basic and clinical research on the vocal types infants produce in the 1st months of life and on their potential diagnostic utility, and may also help improve communication between speech-language pathologists and families.

Conversational Patterns and Listener Responses Associated With an Enhanced Fading Affect Bias After Social Disclosure

The fading affect bias (FAB) is a phenomenon of autobiographical memory whereby negative emotions associated with event memories fade in intensity over time more than positive emotions. Social disclosure enhances the FAB and listener responsiveness during social disclosure is an important facet; however, little is known about the nature of listener verbal responses that facilitate an enhanced FAB. In this study, we used discourse analysis to explore listener verbal responses and conversational patterns associated with an enhanced FAB after social disclosure—backchanneling, in which the listener shows they are paying attention to the story underway; displays of understanding whereby the listener shows awareness of the speaker’s emotional state; and positive facilitation, characterized by mutual development of positive interpretations of both pleasant and unpleasant experiences. We suggest that such listener responses are similar to those described in the verbal person-centered framework, and the emotional benefits of social disclosure are in part collaboratively created by conversationalists.

5. The psychology of music performance

Performers occupy a special role within contemporary Western musical culture. Since two individuals can produce markedly different responses by playing the same notes, it is clear that notation fails to capture some of the most critical dimensions of musical communication. What are these dimensions? What does it take to acquire the kind of expertise in manipulating them that top-notch performers possess? How do listeners perceive and respond to them? “The psychology of music performance” tries to understand this expressive power. It considers expressivity in performance as well as its mechanics, the way that practice shapes performance, listener responses to performer choices, and the processes of creativity and improvisation.
