Differences In Auditory Imagery Self-Report Predict Neural And Behavioral Outcomes, Andrea R. Halpern
Differences In Auditory Imagery Self-Report Predict Neural And Behavioral Outcomes, Andrea R. Halpern
Andrea Halpern
Mental imagery abilities vary among individuals, as shown both by objective measures and by self-report. Few imagery studies consider auditory imagery, however. The Bucknell Auditory Imagery Scale is a short self-report measure encompassing both Vividness and Control subscales for musical, verbal, and environmental sounds. It has high internal reliability, no relation to social desirability, and only a modest relation to musical training. High scores on Vividness predict fewer source memory errors in distinguishing heard from imagined tunes on a recognition test, and better performance on pitch imitation tasks. Furthermore, higher scores are related to hemodynamic response and gray matter volume …
Audience Reactions To Repeating A Piece On A Concert Programme, Andrea R. Halpern, Chloe H.K. Chan, Daniel Müllensiefen, John Sloboda
Audience Reactions To Repeating A Piece On A Concert Programme, Andrea R. Halpern, Chloe H.K. Chan, Daniel Müllensiefen, John Sloboda
Andrea Halpern
Repetition of a piece on a concert programme is a well-established, but uncommon performance practice. Musicians have presumed that repetition benefits audience enjoyment and understanding but no research has examined this. In two naturalistic and one lab study, we examined audience reaction to repeated live performances of contemporary pieces played by the same ensemble. In all studies, we asked listeners to rate their enjoyment and willingness to hear the piece again (Affective), and perceived understanding and predicted memory of the piece (Cognitive). In Study 3, we assessed immediate recognition memory of each excerpt. In all studies, Cognitive variables increased significantly. …
Cerebral Substrates Of Musical Imagery, Andrea R. Halpern
Cerebral Substrates Of Musical Imagery, Andrea R. Halpern
Andrea Halpern
Musical imagery refers to the experience of "replaying" music by imagining it inside the head. Whereas visual imagery has been extensively studied, few people have investigated imagery in the auditory domain. This article reviews a program of research that has tried to characterize auditory imagery for music using both behavioral and cognitive neuroscientific tools. I begin by describing some of my behavioral studies of the mental analogues of musical tempo, pitch, and temporal extent. I then describe four studies using three techniques that examine the correspondence of brain involvement in actually perceiving vs. imagining familiar music. These involve one lesion …
A Brain System For Auditory Working Memory, Sukhbinder Kumar, Sabine Joseph, Phillip E. Gander, Nicolas Barascud, Andrea R. Halpern, Timothy D. Griffiths
A Brain System For Auditory Working Memory, Sukhbinder Kumar, Sabine Joseph, Phillip E. Gander, Nicolas Barascud, Andrea R. Halpern, Timothy D. Griffiths
Andrea Halpern
The brain basis for auditory working memory, the process of actively maintaining sounds in memory over short periods of time, is controversial. Using functional magnetic resonance imaging in human participants, we demonstrate that the maintenance of single tones in memory is associated with activation in auditory cortex. In addition, sustained activation was observed in hippocampus and inferior frontal gyrus. Multivoxel pattern analysis showed that patterns of activity in auditory cortex and left inferior frontal gyrus distinguished the tone that was maintained in memory. Functional connectivity during maintenance was demonstrated between auditory cortex and both the hippocampus and inferior frontal cortex. …
An Erp Study Of Major-Minor Classification In Melodies, Andrea R. Halpern, Jeffrey S. Martin, Tara D. Reed
An Erp Study Of Major-Minor Classification In Melodies, Andrea R. Halpern, Jeffrey S. Martin, Tara D. Reed
Andrea Halpern
Skip to Next Section COMPOSERS COMMONLY USE MAJOR OR MINOR SCALES to create different moods in music.Nonmusicians show poor discrimination and classification of this musical dimension; however, they can perform these tasks if the decision is phrased as happy vs. sad.We created pairs of melodies identical except for mode; the first major or minor third or sixth was the critical note that distinguished major from minor mode. Musicians and nonmusicians judged each melody as major vs. minor or happy vs. sad.We collected ERP waveforms, triggered to the onset of the critical note. Musicians showed a late positive component (P3) to …
Attentional Flexibility And Memory Capacity In Conductors And Pianists, Andrea R. Halpern, Clemens Wöllner
Attentional Flexibility And Memory Capacity In Conductors And Pianists, Andrea R. Halpern, Clemens Wöllner
Andrea Halpern
Individuals with high working memory (WM) capacity also tend to have better selective and divided attention. Although both capacities are essential for skilled performance in many areas, evidence for potential training and expertise effects is scarce. We investigated the attentional flexibility of musical conductors by comparing them to equivalently trained pianists. Conductors must focus their attention both on individual instruments and on larger sections of different instruments. We studied students and professionals in both domains to assess the contributions of age and training to these skills. Participants completed WM span tests for auditory and visual (notated) pitches and timing durations, …
Absolute Pitch In Naturalistic Singing: A Commentary On Olthof Et Al., Andrea R. Halpern
Absolute Pitch In Naturalistic Singing: A Commentary On Olthof Et Al., Andrea R. Halpern
Andrea Halpern
The parent article looks at pitch stability in an archive of folksongs recorded over several decades. Some evidence for pitch stability was found. Here, I consider some additional aspects of the archive that could be examined, offer some extensions to relevant laboratory studies, and consider some inherent strengths and limitations of the naturalistic, archival approach.
Attraction To Sad Music: The Role Of Imagery, Absorption, And Rumination, Emery Schubert, Andrea R. Halpern, Gunter Kreutz, Sandra Garrido
Attraction To Sad Music: The Role Of Imagery, Absorption, And Rumination, Emery Schubert, Andrea R. Halpern, Gunter Kreutz, Sandra Garrido
Andrea Halpern
Previous studies have identified links between attraction to negative emotion in music with the traits of absorption and rumination. However, no studies have examined the possible interdependencies and influences of these traits. We sought to determine whether a cognitive processing path that leads to attraction to sad music could be identified. We argued that auditory imagery might be an interesting competency to add to the investigation because of the links between imagery and absorption. Participants completed validated surveys measuring the three target cognitive measures, as well as a Like Sad Music Scale. Mediation analysis revealed that absorption mediated imagery in …

Grizzly Bear Monitoring By The Heiltsuk People As A Crucible For First Nation Conservation Practice, William G. Housty, Anna Noson, Gerald W. Scoville, John Boulanger, Richard M. Jeo, Chris T. Darimont, Christopher E. Filardi
Chris Darimont, PhD
Guided by deeply held cultural values, First Nations in Canada are rapidly regaining legal authority to manage natural resources. We present a research collaboration among academics, tribal government, provincial and federal government, resource managers, conservation practitioners, and community leaders supporting First Nation resource authority and stewardship. First, we present results from a molecular genetics study of grizzly bears inhabiting an important conservation area within the territory of the Heiltsuk First Nation in coastal British Columbia. Noninvasive hair sampling occurred between 2006 and 2009 in the Koeye watershed, a stronghold for grizzly bears, salmon, and Heiltsuk people. Molecular demographic analyses revealed …
Population Genetic Structure Of Gray Wolves (Canis Lupus) In A Marine Archipelago Suggests Island-Mainland Differentiation Consistent With Dietary Niche, Astrid V. Stronen, Erin L. Navid, Michael S. Quinn, Paul C. Paquet, Heather M. Bryan, Chris T. Darimont
Population Genetic Structure Of Gray Wolves (Canis Lupus) In A Marine Archipelago Suggests Island-Mainland Differentiation Consistent With Dietary Niche, Astrid V. Stronen, Erin L. Navid, Michael S. Quinn, Paul C. Paquet, Heather M. Bryan, Chris T. Darimont
Chris Darimont, PhD
Background: Emerging evidence suggests that ecological heterogeneity across space can influence the genetic structure of populations, including that of long-distance dispersers such as large carnivores. On the central coast of British Columbia, Canada, wolf (Canis lupus L., 1758) dietary niche and parasite prevalence data indicate strong ecological divergence between marine-oriented wolves inhabiting islands and individuals on the coastal mainland that interact primarily with terrestrial prey. Local holders of traditional ecological knowledge, who distinguish between mainland and island wolf forms, also informed our hypothesis that genetic differentiation might occur between wolves from these adjacent environments.
Results: We used microsatellite genetic markers …

Online Hunting Forums Identify Achievement As Prominent Among Multiple Satisfactions, Alena M. Ebeling-Schuld, Chris T. Darimont
Online Hunting Forums Identify Achievement As Prominent Among Multiple Satisfactions, Alena M. Ebeling-Schuld, Chris T. Darimont
Chris Darimont, PhD
Understanding hunter satisfactions can lead to improved wildlife management policy and practice. Whereas previous work has suggested that hunters often seek multiple satisfactions (achievement, affiliation, appreciation), little is known about how satisfactions might vary with target species. Additionally, past research has mostly gathered data using interviews and surveys, which might limit scope as well as introduce strategic bias for potentially provocative subjects such as hunting. To address these gaps, we analyzed data from online hunting forums, which provide an open-access source of peer-to-peer discussion that is geographically and taxonomically broad. We used directed qualitative content analysis to analyze hunting narratives …
What Enables Size-Selective Trophy Hunting Of Wildlife?, Chris T. Darimont, K. Rosie Child
What Enables Size-Selective Trophy Hunting Of Wildlife?, Chris T. Darimont, K. Rosie Child
Chris Darimont, PhD
Although rarely considered predators, wildlife hunters can function as important ecological and evolutionary agents. In part, their influence relates to targeting of large reproductive adults within prey populations. Despite known impacts of sizeselective harvests, however, we know little about what enables hunters to kill these older, rarer, and presumably more wary individuals. In other mammalian predators, predatory performance varies with knowledge and physical condition, which accumulates and declines, respectively, with age. Moreover, some species evolved camouflage as a physical trait to aid in predatory performance. In this work, we tested whether knowledge-based faculty (use of a hunting guide with accumulated …
Intrapopulation Diversity In Isotopic Niche Over Landscapes: Spatial Patterns Inform Conservation Of Bear–Salmon Systems, Megan S. Adams, Christina N. Service, Andrew Bateman, Mathieu Bourbonnais, Kyle A. Artelle, Trisalyn Nelson, Paul C. Paquet, Taal Levi, Chris T. Darimont

Chris Darimont, PhD
Intrapopulation variability in resource acquisition (i.e., niche variation) influences population dynamics, with important implications for conservation planning. Spatial analyses of niche variation within and among populations can provide relevant information about ecological associations and their subsequent management. We used stable isotope analysis and kernel-weighted regression to examine spatial patterns in a keystone consumer–resource interaction: salmon (Oncorhynchus spp.) consumption by grizzly and black bears (Ursus arctos horribilis, n = 886; and Ursus americanus, n = 557) from 1995 to 2014 in British Columbia (BC), Canada. In a region on the central coast of BC (22,000 km2 ), grizzly bears consumed …

Maintaining Ethical Standards During Conservation Crises, Ryan K. Brook, Mark Cattet, Chris T. Darimont, Paul C. Paquet, Gilbert Proulx
Chris Darimont, PhD
Many species at risk in Canada and globally are at or approaching a crisis, especially where little or nothing consequential is being done to prevent extirpation. Such is the case of endangered boreal caribou (Rangifer tarandus caribou) in southern Alberta, Canada. Expedient but inadequate emergency ‘fixes’ have been experimentally implemented to arrest their decline and potential extirpation, but use of these measures raises important ethical problems. In their study of the effects of killing wolves (Canis lupus) on the Little Smoky woodland caribou population, Hervieux et al. (2014a) employed lethal methods that included shooting a firearm from a helicopter and …

The Elephant (Head) In The Room: A Critical Look At Trophy Hunting, Chelsea Batavia, Michael Paul Nelson, Chris T. Darimont, Paul C. Paquet, William J. Ripple, Arian D. Wallach
Chris Darimont, PhD
Trophy hunting has occupied a prominent position in recent scholarly literature and popular media. In the scientific conservation literature, researchers are generally supportive of or sympathetic to its usage as a source of monetary support for conservation. Although authors at times acknowledge that trophy hunting faces strong opposition from many members of the public, often for unspecified reasons associated with ethics, neither the nature nor the implications of these ethical concerns have been substantively addressed. We identify the central act of wildlife “trophy” taking as a potential source of ethical discomfort and public opposition. We highlight that trophy hunting entails …

Why Men Trophy Hunt, Chris T. Darimont, Brian F. Codding, Kristen Hawkes
Chris Darimont, PhD
The killing of Cecil the lion (Panthera leo) ignited enduring and increasingly global discussion about trophy hunting. Yet, policy debate about its benefits and costs focuses only on the hunted species and biodiversity, not the unique behaviour of hunters. Some contemporary recreational hunters from the developed world behave curiously, commonly targeting ‘trophies’: individuals within populations with large body or ornament size, as well as rare and/or inedible species, like carnivores. Although contemporary hunters have been classified according to implied motivation (i.e. for meat, recreation, trophy or population control, as well the ‘multiple satisfactions’ they seek while hunting (affiliation, …
Mismeasured Mortality: Correcting Estimates Of Wolf Poaching In The United States, Adrian Treves, Kyle A. Artelle, Chris T. Darimont, David R. Parsons
Mismeasured Mortality: Correcting Estimates Of Wolf Poaching In The United States, Adrian Treves, Kyle A. Artelle, Chris T. Darimont, David R. Parsons
Chris Darimont, PhD
Measuring rates and causes of mortalities is important in animal ecology and management. Observing the fates of known individuals is a common method of estimating life history variables, including mortality patterns. It has long been assumed that data lost when known animals disappear were unbiased. We test and reject this assumption under conditions common to most, if not all, studies using marked animals. We illustrate the bias for 4 endangered wolf populations in the United States by reanalyzing data and assumptions about the known and unknown fates of marked wolves to calculate the degree to which risks of different causes …
Indigenous Knowledge And Science Unite To Reveal Spatial And Temporal Dimensions Of Distributional Shift In Wildlife Of Conservation Concern, Christina N. Service, Megan S. Adams, Kyle A. Artelle, Paul C. Paquet, Laura V. Grant, Chris T. Darimont
Indigenous Knowledge And Science Unite To Reveal Spatial And Temporal Dimensions Of Distributional Shift In Wildlife Of Conservation Concern, Christina N. Service, Megan S. Adams, Kyle A. Artelle, Paul C. Paquet, Laura V. Grant, Chris T. Darimont
Chris Darimont, PhD
Range shifts among wildlife can occur rapidly and impose cascading ecological, economic, and cultural consequences. However, occurrence data used to define distributional limits derived from scientific approaches are often outdated for wide ranging and elusive species, especially in remote environments. Accordingly, our aim was to amalgamate indigenous and western scientific evidence of grizzly bear (Ursus arctos horribilis) records and detail a potential range shift on the central coast of British Columbia, Canada. In addition, we test the hypothesis that data from each method yield similar results, as well as illustrate the complementary nature of this coupled approach. Combining information from …
Hunting As A Management Tool? Cougar-Human Conflict Is Positively Related To Trophy Hunting, Kristine J. Teichman, Bogdan Cristescu, Chris T. Darimont
Hunting As A Management Tool? Cougar-Human Conflict Is Positively Related To Trophy Hunting, Kristine J. Teichman, Bogdan Cristescu, Chris T. Darimont
Chris Darimont, PhD
Background: Overexploitation and persecution of large carnivores resulting from conflict with humans comprise major causes of declines worldwide. Although little is known about the interplay between these mortality types, hunting of predators remains a common management strategy aimed at reducing predator-human conflict. Emerging theory and data, however, caution that such policy can alter the age structure of populations, triggering increased conflict in which conflict-prone juveniles are involved.
Results: Using a 30-year dataset on human-caused cougar (Puma concolor) kills in British Columbia (BC), Canada, we examined relationships between hunter-caused and conflict-associated mortality. Individuals that were killed via conflict with humans were …

Ecology Of Conflict: Marine Food Supply Affects Human-Wildlife Interactions On Land, Kyle A. Artelle, Sean Anderson, John D. Reynolds, Andrew B. Cooper, Paul C. Paquet, Chris T. Darimont
Chris Darimont, PhD
Human-wildlife conflicts impose considerable costs to people and wildlife worldwide. Most research focuses on proximate causes, offering limited generalizable understanding of ultimate drivers. We tested three competing hypotheses (problem individuals, regional population saturation, limited food supply) that relate to underlying processes of human-grizzly bear (Ursus arctos horribilis) conflict, using data from British Columbia, Canada, between 1960–2014. We found most support for the limited food supply hypothesis: in bear populations that feed on spawning salmon (Oncorhynchus spp.), the annual number of bears/km2killed due to conflicts with humans increased by an average of 20% (6–32% [95% CI]) for each 50% …
