Preliminary evidence for selective cortical responses to music in one-month-old infants

Prior studies have observed selective neural responses in the adult human auditory cortex to music and speech that cannot be explained by the differing lower-level acoustic properties of these stimuli. Does infant cortex exhibit similarly selective responses to music and speech shortly after birth? To answer this question, we attempted to collect functional magnetic resonance imaging (fMRI) data from 45 sleeping infants (2.0- to 11.9-weeks-old) while they listened to monophonic instrumental lullabies and infant-directed speech produced by a mother. To match acoustic variation between music and speech sounds we (1) recorded music from instruments that had a similar spectral range as female infant-directed speech, (2) used a novel excitation-matching algorithm to match the cochleagrams of music and speech stimuli, and (3) synthesized “model-matched” stimuli that were matched in spectrotemporal modulation statistics to (yet perceptually distinct from) music or speech. Of the 36 infants we collected usable data from, 19 had significant activations to sounds overall compared to scanner noise. From these infants, we observed a set of voxels in non-primary auditory cortex (NPAC) but not in Heschl's Gyrus that responded significantly more to music than to each of the other three stimulus types (but not significantly more strongly than to the background scanner noise). In contrast, our planned analyses did not reveal voxels in NPAC that responded more to speech than to model-matched speech, although other unplanned analyses did. These preliminary findings suggest that music selectivity arises within the first month of life. A video abstract of this article can be viewed at https://youtu.be/c8IGFvzxudk .

Research Highlights

• Responses to music, speech, and control sounds matched for the spectrotemporal modulation-statistics of each sound were measured from 2- to 11-week-old sleeping infants using fMRI.
• Auditory cortex was significantly activated by these stimuli in 19 out of 36 sleeping infants.
• Selective responses to music compared to the three other stimulus classes were found in non-primary auditory cortex but not in nearby Heschl's Gyrus.
• Selective responses to speech were not observed in planned analyses but were observed in unplanned, exploratory analyses.

     

A translational application of music for preschool cognitive development: RCT evidence for improved executive function,self-regulation,and school readiness

The benefits of active music participation and training for cognitive development have been evidenced in multiple studies, with this link leveraged in music therapy approaches with clinical populations. Although music, rhythm, and movement activities are widely integrated into children's play and early education, few studies have systematically translated music therapy-based approaches to a nonclinical population to support early cognitive development. This study reports the follow-up effects of the Rhythm and Movement for Self Regulation (RAMSR) program delivered by generalist preschool teachers in low socioeconomic communities. This randomized control trial (RCT) involved 213 children across eight preschools in disadvantaged communities in Queensland, Australia. The intervention group received 16–20 sessions of RAMSR over 8 weeks, while the control group undertook usual preschool programs. Primary outcome measures included executive function (child assessment of shifting, working memory, and inhibition) and self-regulation (teacher report), with secondary outcomes of school readiness and visual-motor integration. Data were collected pre- and post-intervention, and again 6 months later once children had transitioned into school. Results demonstrated significant intervention effects across the three time points for school readiness (p = 0.038, η_p² = 0.09), self-regulation (p < 0.001, η_p² = 0.08), and inhibition (p = 0.002 η_p² = 0.23). Additionally, the feasibility of building capacity in teachers without any music background to successfully deliver the program was evidenced. These findings are important given that children from low socioeconomic backgrounds are more likely to need support for cognitive development yet have inequitable access to quality music and movement programs.

Research Highlights

• Initial effects of self-regulation from a rhythm and movement program were sustained following transition into school for children from disadvantaged backgrounds.
• Delayed effects of inhibition and school readiness from a rhythm and movement program appeared 6 months post-intervention as children entered school.
• Generalist teachers can successfully implement a rhythm and movement program, which boosts critical developmental cognitive skills.

     

VOCATION AND CREATION: BEYOND THE GENTILE‐HOMOSEXUAL ANALOGY

One strand of the church's conversation about homosexuality compares present‐day acceptance of homosexuals to the church's acceptance of Gentiles in Acts 15. In a previous article, “Gentiles and Homosexuals,” I presented the history of that strand. In a reply to my article, Olson proposes to reimagine the analogy via the “radical new perspective on Paul” and argues that doing so exposes problems with my original analysis. I defend myself against these criticisms, while also entering into the spirit of Olson's reimagined analogy. Expanding the scope beyond Acts to Paul opens up important facets that might otherwise be obscured. In particular, it includes voices that are sometimes silenced, and presses both sides for an account of sexuality grounded in vocation and God's purposes in creation.     

STAGE‐TWO SECULARITY AND THE FUTURE OF THEOLOGY‐AND‐SCIENCE

Charles Taylor has recently provided an in‐depth exploration of secularity, with a central characteristic being the understanding that religious commitment is optional. This essay extends this analysis, considering the possibility that American society may be entering a second stage of secularity, one in which the possibility of religious commitment ceases to be an option at all for many. The possible implications of such a development are considered for the theology‐and‐science dialogue.     

OBJECT-ORIENTED ONTOLOGY AND THE OTHER OF WE IN ANTHROPOCENTRIC POSTHUMANISM

The object-oriented ontology group of philosophies, and certain strands of posthumanism, overlook important ethical and biological differences, which make a difference. These allied intellectual movements, which have at times found broad popular appeal, attempt to weird life as a rebellion to the forced melting of lifeforms through the artefacts of capitalist realism. They truck, however, in a recursive solipsism resulting in ontological flattening, overlooking that things only show up to us according to our attunement to them. Ecology and biology tend to get lost in the celebration of “thingness,” which puts on par artifacts, trash, and living beings. Such abstractions fail to understand the political, ethical, and ontological implications of eliding the animate/nonanimate distinction, which from the opposite direction (of flattening) reproduce the same violences of historical colonialism (hierarchical humanism). I argue that ontological flattening entails epistemological narcissism, fails to take into account plural (interspecies) perspectives, and propose biosemiotics can address these shortcomings through becoming-with nonhuman knowledge.     

Analysis of the Movement-Inducing Effects of Music through the Fractality of Head Sway during Standstill

Abstract

The links between music and human movement have been shown to provide insight into crucial aspects of human’s perception, cognition, and sensorimotor systems. In this study, we examined the influence of music on movement during standstill, aiming at further characterizing the correspondences between movement, music, and perception, by analyzing head sway fractality. Eighty seven participants were asked to stand as still as possible for 500?seconds while being presented with alternating silence and audio stimuli. The audio stimuli were all rhythmic in nature, ranging from a metronome track to complex electronic dance music. The head position of each participant was captured with an optical motion capture system. Long-range correlations of head movement were estimated by detrended fluctuation analysis (DFA). Results agree with previous work on the movement-inducing effect of music, showing significantly greater head sway and lower head sway fractality during the music stimuli. In addition, patterns across stimuli suggest a two-way adaptation process to the effects of music, with musical stimuli influencing head sway while at the same time fractality modulated movement responses. Results indicate that fluctuations in head movement in both conditions exhibit long-range correlations, suggesting that the effects of music on head movement depended not only on the value of the most recent measured intervals, but also on the values of those intervals at distant times.     

Utilizing a Music Listening Technique in Inpatient Psychiatric Group Counseling

ABSTRACT

The purpose of this article is to describe and illustrate through a hypothetical case example how counselors can utilize an expressive arts technique called music listening in inpatient psychiatric group counseling. The authors give a rationale to implement here-and-now interventions, specifically music listening, in response to the critique of current inpatient therapy in psychiatric hospitals following a shift from long-term inpatient psychiatric care to brief stabilization admissions.     

Familiarity and categorization processes in memory search

A fundamental distinction in tasks of memory search is whether items receive varied mappings (targets and distractors switch roles across trials) or consistent mappings (targets and distractors never switch roles). The type of mapping often produces markedly different performance patterns, but formal memory-based models that account quantitatively for detailed aspects of the results have not yet been developed and evaluated. Experiments were conducted to test a modern exemplar-retrieval model on its ability to account for memory-search performance involving a wide range of memory-set sizes in both varied-mapping (VM) and consistent-mapping (CM) probe-recognition tasks. The model formalized the idea that both familiarity-based and categorization-based processes operate. The model was required to fit detailed response-time (RT) distributions of individual, highly practiced subjects. A key manipulation involved the repetition of negative probes across trials. This manipulation produced a dramatic dissociation: False-alarm rates increased and correct-rejection RTs got longer in VM, but not in CM. The qualitative pattern of results and modeling analyses provided evidence for a strong form of categorization-based processing in CM, in which observers made use of the membership of negative probes in the “new” category to make old–new recognition decisions.
