Shadows of music-language interaction on low frequency brain oscillatory patterns

Electrophysiological studies investigating similarities between music and language perception have relied exclusively on the signal averaging technique, which does not adequately represent oscillatory aspects of electrical brain activity that are relevant for higher cognition. The current study investigated the patterns of brain oscillations during simultaneous processing of music and language using visually presented sentences and auditorily presented chord sequences. Music-syntactically regular or irregular chord functions were presented in sync with syntactically or semantically correct or incorrect words. Irregular chord functions (presented simultaneously with a syntactically correct word) produced an early (150-250 ms) spectral power decrease over anterior frontal regions in the theta band (5-7 Hz) and a late (350-700 ms) power increase in both the delta and the theta band (2-7 Hz) over parietal regions. Syntactically incorrect words (presented simultaneously with a regular chord) elicited a similar late power increase in delta-theta band over parietal sites, but no early effect. Interestingly, the late effect was significantly diminished when the language-syntactic and music-syntactic irregularities occurred at the same time. Further, the presence of a semantic violation occurring simultaneously with regular chords produced a significant increase in later delta-theta power at posterior regions; this effect was marginally decreased when the identical semantic violation occurred simultaneously with a music syntactical violation. Altogether, these results show that low frequency oscillatory networks get activated during the syntactic processing of both music and language, and further, these networks may possibly be shared.     

The effect of harmonic context on phoneme monitoring in vocal music

The processing of a target chord depends on the previous musical context in which it has appeared. This harmonic priming effect occurs for fine syntactic-like changes in context and is observed irrespective of the extent of participants' musical expertise (Bigand & Pineau, Perception and Psychophysics, 59 (1997) 1098). The present study investigates how the harmonic context influences the processing of phonemes in vocal music. Eight-chord sequences were presented to participants. The four notes of each chord were played with synthetic phonemes and participants were required to quickly decide whether the last chord (the target) was sung on a syllable containing the phoneme /i/ or /u/. The musical relationship of the target chord to the previous context was manipulated so that the target chord acted as a referential tonic chord or as a congruent but less structurally important subdominant chord. Phoneme monitoring was faster for the tonic chord than for the subdominant chord. This finding has several implications for music cognition and speech perception. It also suggests that musical and phonemic processing interact at some stage of processing.     

Sad Mood and Music Choice: Does the Self-Relevance of the Mood-Eliciting Stimulus Moderate Song Preference?

Recent findings regarding the influence of sad mood on music preference have been inconsistent, with some research suggesting that sadness promotes selective exposure to happy music and other work suggesting the very opposite. In three experiments, we investigated whether this discrepancy may have resulted from differences in the extent to which sadness was elicited by having participants think about personally relevant versus personally irrelevant negative events. To this end, we manipulated sad mood via a guided visualization technique in which participants were led to imagine experiencing a loss that was relevant either to their own or to an unfamiliar individual's concerns. Results revealed that irrespective of the self-relevance of the mood induction, individuals in sad, relative to happy, or neutral moods preferred to avoid expressively happy music. This aversion was partially mediated by beliefs that choosing happy music while sad would be inappropriate and thereby ineffectual in mood repair. Together, these findings contribute to resolving discrepancies in the literature and help advance understanding of the influence of mood on music choice.     

Effect of mindfulness meditation on brain–computer interface performance

Electroencephalogram based brain–computer interfaces (BCIs) enable stroke and motor neuron disease patients to communicate and control devices. Mindfulness meditation has been claimed to enhance metacognitive regulation. The current study explores whether mindfulness meditation training can thus improve the performance of BCI users. To eliminate the possibility of expectation of improvement influencing the results, we introduced a music training condition. A norming study found that both meditation and music interventions elicited clear expectations for improvement on the BCI task, with the strength of expectation being closely matched. In the main 12 week intervention study, seventy-six healthy volunteers were randomly assigned to three groups: a meditation training group; a music training group; and a no treatment control group. The mindfulness meditation training group obtained a significantly higher BCI accuracy compared to both the music training and no-treatment control groups after the intervention, indicating effects of meditation above and beyond expectancy effects.     

The tonal function of a task-irrelevant chord modulates speed of visual processing

Harmonic priming studies have provided evidence that musical expectations influence sung phoneme monitoring, with facilitated processing for phonemes sung on tonally related (expected) chords in comparison to less-related (less-expected) chords [Bigand, Tillmann, Poulin, D’Adamo, and Madurell (2001). The effect of harmonic context on phoneme monitoring in vocal music. Cognition, 81, B11–B20]. This tonal relatedness effect has suggested two interpretations: (a) processing of music and language interact at some level of processing; and (b) tonal functions of chords influence task performance via listeners’ attention. Our study investigated these hypotheses by exploring whether the effect of tonal relatedness extends to the processing of visually presented syllables (Experiments 1 and 2) and geometric forms (Experiments 3 and 4). For Experiments 1–4, visual target identification was faster when the musical background fulfilled listeners’ expectations (i.e., a related chord was played simultaneously). In Experiment 4, the addition of a baseline condition (i.e., without an established tonal center) further showed that the observed difference was due to a facilitation linked to the related chord and not to an inhibition or disruption caused by the less-related chord. This outcome suggests the influence of musical structures on attentional mechanisms and that these mechanisms are shared between auditory and visual modalities. The implications for research investigating neural correlates shared by music and language processing are discussed.     

Musical structure modulates semantic priming in vocal music

It has been shown that harmonic structure may influence the processing of phonemes whatever the extent of participants' musical expertise [Bigand, E., Tillmann, B., Poulin, B., D'Adamo, D. A., & Madurell, F. (2001). The effect of harmonic context on phoneme monitoring in vocal music. Cognition, 81, B11-B20]. The present study goes a step further by investigating how musical harmony may potentially interfere with the processing of words in vocal music. Eight-chord sung sentences were presented, their last word being either semantically related (La girafe a un tres grand cou, The giraffe has a very long neck) or unrelated to the previous linguistic context (La girafe a un tres grand pied, The giraffe has a very long foot). The target word was sung on a chord that acted either as a referential tonic chord or as a congruent but less referential subdominant chord. Participants performed a lexical decision task on the target word. A significant interaction was observed between semantic and harmonic relatedness suggesting that music modulates semantic priming in vocal music. Following Jones' dynamic attention theory, we argue that music can modulate semantic priming in vocal music, by modifying the allocation of attentional resource necessary for linguistic computation.     

Perceptual integrality of major chord components

In the present study, an accuracy, rather than a reaction time, version of the Garner paradigm was used to evaluate the integrality or separability of major chord components. Tuned (prototype, or P) and mistuned (nonprototype, or NP) sets of root position C-major triads were constructed by holding the C constant in all stimuli and varying the E and G frequencies in 2- and 4-Hz steps. The P stimuli represent small systematic mistunings in the E and G notes relative to an equal-tempered C-major chord. The NP stimuli represent an equivalent range of frequency variation, but relative to a significantly out-of-tune C-major triad. In different experimental sessions, asame-different (AX) task was used to separately evaluate discrimination performance for the E and G frequencies as a function of whether the nontarget frequency (G or E) was fixed or varied in either a correlated or an orthogonal fashion (with the C frequency always held constant). Compared with a fixed baseline condition where only the target frequency changed, both chord components exhibited a significant redundancy gain in the correlated conditions and, to varying degrees, significant interference effects in the orthogonal condition, indicating that the chord components function largely in an integral fashion. Relative to the discrimination of G, discrimination of the E frequency was less influenced by variation in the nontarget (G) frequency, showing that attention, to some degree, could be selectively allocated to the E chord component. In addition, the results were consistent with previous findings that the functional prototype for the major chord category seems to act as a perceptual anchor, rather than as a magnet, and appears to be located in the physiologically defined area of just temperament, as opposed to the more experientially defined area ofequal temperament.     

Modularity in musical processing: the automaticity of harmonic priming

Three experiments investigated the modularity of harmonic expectations that are based on cultural schemata despite the availability of more predictive veridical information. Participants were presented with prime-target chord pairs and made an intonation judgment about each target. Schematic expectation was manipulated by the combination of prime and target, with some transitions being schematically more probable than others. Veridical information in the form of prime-target previews, local transition probabilities, or valid versus invalid previews was also provided. Processing was facilitated when a schematically probable target chord followed the prime. Furthermore, this effect was independent of all manipulations of veridical expectation. A solution to L. B. Meyer's (1967b) query "On Rehearing Music" is suggested, in which schematic knowledge contributes to harmonic expectation in a modular manner regardless of whether any veridical knowledge exists.     

Musical duplex perception: perception of figurally good chords with subliminal distinguishing tones.

In a variant of duplex perception with speech, phoneme perception is maintained when distinguishing components are presented below intensities required for separate detection, forming the basis for the claim that a phonetic module takes precedence over nonspeech processing. This finding is replicated with music chords (C major and minor) created by mixing a piano fifth with a sinusoidal distinguishing tone (E or E flat). Individual threshold intensities for detecting E or E flat in the context of the fixed piano tones are established. Chord discrimination thresholds defined by distinguishing tone intensity were determined. Experiment 2 verified masked detection thresholds and subliminal chord identification for experienced musicians. Accurate chord perception was maintained at distinguishing tone intensities nearly 20 dB below the threshold for separate detection. Speech and music findings are argued to demonstrate general perceptual principles.

Perceptions of Confidentiality Violations Among Psychologists

This study explored psychologists' perceptions of confidentiality violations. One hundred ninety-five psychologists answered questionnaires about a vignette regarding a male therapist accused of violating the confidentiality of a female client. The vignette varied on the following variables: (a) Confidential information was conveyed to either an insurance company or another client, (b) the therapist's account of the violation included either an excuse or a justification, and (c) scapegoating was included or not included in the account. The insurance condition and excuse condition produced more lenient judgments of the violation. However, excuses elicited more negative judgments of the therapist. Scapegoating generally elicited more negative judgments. Differences in the recipient of confidential information and the accounts given for violations have an impact on psychologists' perceptions of confidentiality violations.     

Harmonic and rhythmic influences on musical expectancy

The effects of harmony and rhythm on expectancy formation were studied in two experiments. In both studies, we generated musical passages consisting of a melodic line accompanied by four harmonic (chord) events. These sequences varied in their harmonic content, the rhythmic periodicity of the three context chords prior to the final chord, and the ending time of the final chord itself. In Experiment 1, listeners provided ratings for how well the final chord in a chord sequence fit their expectations for what was to come next; analyses revealed subtle changes in ratings as a function of both harmonic and rhythmic variation. Experiment 2 extended these results; listeners made a speeded reaction time judgment on whether the final chord of a sequence belonged with its set of context chords. Analysis of the reaction time data suggested that harmonic and rhythmic variation also influenced the speed of musical processing. These results are interpreted with reference to current models of music cognition, and they highlight the need for rhythmical weighting factors within the psychological representation of tonal/pitch information.     

Children's implicit knowledge of harmony in Western music

Three experiments examined children's knowledge of harmony in Western music. The children heard a series of chords followed by a final, target chord. In Experiment 1, French 6- and 11-year-olds judged whether the target was sung with the vowel /i/ or /u/. In Experiment 2, Australian 8- and 11-year-olds judged whether the target was played on a piano or a trumpet. In Experiment 3, Canadian 8- and 11-year-olds judged whether the target sounded good (i.e. consonant) or bad (dissonant). The target was either the most stable chord in the established musical key (i.e. the tonic, based on do, the first note of the scale) or a less stable chord. Performance was faster (Experiments 1, 2 and 3) and more accurate (Experiment 3) when the target was the tonic chord. The findings confirm that children have implicit knowledge of syntactic functions that typify Western harmony.     

Evidence for early arousal‐based differentiation of emotions in children’s musical production

Accurate perception and production of emotional states is important for successful social interactions across the lifespan. Previous research has shown that when identifying emotion in faces, preschool children are more likely to confuse emotions that share valence, but differ in arousal (e.g. sadness and anger) than emotions that share arousal, but differ on valence (e.g. anger and joy). Here, we examined the influence of valence and arousal on children's production of emotion in music. Three‐, 5‐ and 7‐year‐old children recruited from the greater Hamilton area (N = 74) ‘performed’ music to produce emotions using a self‐pacing paradigm, in which participants controlled the onset and offset of each chord in a musical sequence by repeatedly pressing and lifting the same key on a MIDI piano. Key press velocity controlled the loudness of each chord. Results showed that (a) differentiation of emotions by 5‐year‐old children was mainly driven by arousal of the target emotion, with differentiation based on both valence and arousal at 7 years and (b) tempo and loudness were used to differentiate emotions earlier in development than articulation. The results indicate that the developmental trajectory of emotion understanding in music may differ from the developmental trajectory in other domains.     

Jazz and Musical Works: Hypnotized by the Wrong Model

It is difficult to place jazz within a philosophy of music dominated by the concepts and practices of classical music. One key puzzle concerns the nature and role, if any, of musical works in jazz. I briefly describe the debate between those who deny that there are musical works in jazz (Andrew Kania) and those who affirm that there are such (Julian Dodd and others), and I distinguish between claiming that there are no musical works in the jazz tradition and the more provocative claim that they are not performed in jazz performances. I argue that each side of this debate is partially right and that the first step toward resolving the puzzle is to reject inappropriate concepts of a musical work. In particular, Kania's and Lydia Goehr's accounts, derived from classical music practice, are rejected as general accounts of musical works. I then contrast the norms governing work performance in classical music (the werktreue ideal) with the practices governing performances of works in jazz, which I call realization or staging. Finally, I propose a model of jazz appreciation that incorporates a role for jazz works and that fundamentally differs from the way that classical musical performances are appreciated.     

Shared structural and temporal integration resources for music and arithmetic processing

While previous research has investigated the relationship either between language and music processing or between language and arithmetic processing, the present study investigated the relationship between music and arithmetic processing. Rule-governed number series, with the final number being a correct or incorrect series ending, were visually presented in synchrony with musical sequences, with the final chord functioning as the expected tonic or the less-expected subdominant chord (i.e., tonal function manipulation). Participants were asked to judge the correctness of the final number as quickly and accurately as possible. The results revealed an interaction between the processing of series ending and the processing of the task-irrelevant chords' tonal function, thus suggesting that music and arithmetic processing share cognitive resources. These findings are discussed in terms of general temporal and structural integration resources for linguistic and non-linguistic rule-governed sequences.     

Dynamic processes in music perception

A schema-based theory of music perception that describes the dynamic interaction between the musical event and the listener’s knowledge of the underlying regularities in tonal music is proposed. Three properties of musical schema are evaluated in a recognition memory experiment: (1) The schema engages a subset of the abstract knowledge system that is determined by the predominant key of the musical sequence, (2) the schema evaluates both interval relations and the functions of the sounded elements within the established tonal framework, and (3) the schema interacts continuously with the musical event in time to process pitch information in its temporal context. Listeners are required to identify the serial position of a chord that is changed between two successive chord sequences that are otherwise identical. The experiment measures the magnitude and the temporal extent of the disruptive effect of including in the sequence an element outside the tonal framework. The results show temporally specific effects on memory for pitch relations consistent with the operation of a musical schema. Comparisons are made with schema-based theories applied in other perceptual and cognitive domains.     

Using equivalence‐based instruction to teach piano skills to college students

The purpose of the current study was to evaluate the effects of equivalence‐based instruction (EBI) on the emergence of basic music reading and piano playing skills. Six female college students learned to identify three musical chord notations given their respective dictated names. Participants also learned to play chords on the piano following the dictated name of the chord, and to play the chords to a song on a keyboard. Results are consistent with past research, in that stimuli became substitutable for each other and acquired a common behavioral function. Data suggest that EBI was an effective and efficient procedure to teach adults to read musical notation, as well as play chords and a song on a piano keyboard.     

Action Interrupted: Movement and Breakpoints in the Processing of Motion Violations in Toddlers and Adults

From early in development, segmenting events unfolding in the world in meaningful ways renders input more manageable and facilitates interpretation and prediction. Yet, little is known about how children process action structure in events composed of multiple coarse-grained actions. More importantly, little is known about the time course of action processing in young children or about the specific features that recruit attention. This is particularly true when we consider action that pauses unexpectedly—as actions sometimes do—thereby violating the expectation of a continuous unfolding of motion. We assessed visual preference to intact and disrupted actions embedded within a multiaction event in toddlers and adults. In 1 condition, pauses were inserted at intact action boundaries, whereas in the other condition, they disrupted action. Attention in both groups was recruited to the disrupted relative to intact events. Time-course analyses, however, revealed developmental differences in sensitivity to the movement features (e.g., motion, pauses, and transitions) of disrupted events.     

Emotions induced by operatic music: psychophysiological effects of music, plot, and acting: a scientist's tribute to Maria Callas

Operatic music involves both singing and acting (as well as rich audiovisual background arising from the orchestra and elaborate scenery and costumes) that multiply the mechanisms by which emotions are induced in listeners. The present study investigated the effects of music, plot, and acting performance on emotions induced by opera. There were three experimental conditions: (1) participants listened to a musically complex and dramatically coherent excerpt from Tosca; (2) they read a summary of the plot and listened to the same musical excerpt again; and (3) they re-listened to music while they watched the subtitled film of this acting performance. In addition, a control condition was included, in which an independent sample of participants succesively listened three times to the same musical excerpt. We measured subjective changes using both dimensional, and specific music-induced emotion questionnaires. Cardiovascular, electrodermal, and respiratory responses were also recorded, and the participants kept track of their musical chills. Music listening alone elicited positive emotion and autonomic arousal, seen in faster heart rate, but slower respiration rate and reduced skin conductance. Knowing the (sad) plot while listening to the music a second time reduced positive emotions (peacefulness, joyful activation), and increased negative ones (sadness), while high autonomic arousal was maintained. Watching the acting performance increased emotional arousal and changed its valence again (from less positive/sad to transcendent), in the context of continued high autonomic arousal. The repeated exposure to music did not by itself induce this pattern of modifications. These results indicate that the multiple musical and dramatic means involved in operatic performance specifically contribute to the genesis of music-induced emotions and their physiological correlates.
