New Paper – Neural predictors of fear depend on the situation
11/13/2024
When you feel fear does it engage the same brain regions regardless of context? Or are the brain representations of fear context dependent? In this study, we used examined whether and which brain regions carry functional activity that predicts fear across three diverse contexts: fear of heights, social threats, and spiders. Using predictive modeling, we found that functional activity that predicts fear was widely distributed throughout much of the brain, and also variably distributed in that it predicted fear in one or two situations, but hardly every all three. These findings suggest that brain representations of fear are functional heterogeneous.

New Paper – More than labels: neural representations of emotion words are widely distributed across the brain
6/21/2024
Although emotion words such as “anger,” “disgust,” “happiness,” or “pride” are often thought of as mere labels, increasing evidence points to language as being important for emotion perception and experience. In this study, we used representational similarity analysis to identify which brain regions carry information about discrete emotion concepts. Our findings showed that information about particular emotion categories – as activated by simply reading emotion words – was widely distributed throughout the brain spanning prefrontal, midline cortical, and sensorimotor regions. Notably, our results overlapped with many regions implicated in decoding full-fledged emotion experience by prior studies, raising questions about what processes are being supported by these regions during emotion experience.

Congrats Ajay!! Hopefully SANS stays afloat!
Grad student, Alessia Iancarelli, was awarded a PsiChi Grant to study aggression!
12/8/2023
Alessia is studying how emotions influence attitudes toward punishment and aggression. While much research focusses on the psychological causes and consequences of aggression between perpetrators and targets, often overlooked is the crucial role of 3rd party observers (3POs), who can have direct influences on the parties involved (e.g., as jury members) or whose attitudes constitute whether and how society condones aggression and violence in general. Her work will examine whether, and in which situations, anger increases the degree to which people condone punishment toward others. Congrats Alessia!
New Paper – Fear-related psychophysiological patterns are situation and individual dependent: A Bayesian model comparison approach
August 25, 2023
Is there a universal mapping of physiology to emotion, or do these mappings vary substantially by person or situation? Psychologists, philosophers, and neuroscientists have debated this question for decades. Most previous studies have focused on differentiating emotions on the basis of accompanying autonomic responses using analytical approaches that often assume within-category homogeneity. In the present study, we took an alternative approach to this question. We determined the extent to which the relationship between subjective experience and autonomic reactivity generalizes across, or depends upon, the individual and situation for instances of a single emotion category, specifically, fear. Electrodermal activity and cardiac activity—two autonomic measures that are often assumed to show robust relationships with instances of fear—were recorded while participants reported fear experience in response to dozens of fear-evoking videos related to three distinct situations: spiders, heights, and social encounters. We formally translated assumptions from diverse theoretical models into a common framework for model comparison analyses. Results exceedingly favored a model that assumed situation-dependency in the relationship between fear experience and autonomic reactivity, with subject variance also significant but constrained by situation. Models that assumed generalization across situations and/or individuals performed much worse by comparison. These results call into question the assumption of generalizability of autonomic-subjective mappings across instances of fear, as required in translational research from nonhuman animals to humans, and advance a situated approach to understanding the autonomic correlates of fear experience.

New Paper – Using citation network analysis to enhance scholarship in psychological science: A case study of the human aggression literature
April 22, 2022
Researchers cannot keep up with the volume of articles being published each year. In order to develop adequate expertise in a given field of study, students and early career scientists must be strategic in what they decide to read. Here we propose using citation network analysis to characterize the literature topology of a given area. We used the human aggression literature as our example. Our citation network analysis identified 15 research communities on aggression. The five largest communities were: “media and video games”, “stress, traits and aggression”, “rumination and displaced aggression”, “role of testosterone”, and “social aggression”. We examined the growth of these research communities over time, and we used graph theoretic approaches to identify the most influential papers within each community and the “bridging” articles that linked distinct communities to one another. Finally, we also examined whether our citation network analysis would help mitigate gender bias relative to focusing on total citation counts. The percentage of articles with women first authors doubled when identifying influential articles by community structure versus citation count. Our approach of characterizing literature topologies using citation network analysis may provide a valuable resource for psychological scientists by outlining research communities and their growth over time, identifying influential papers within each community (including bridging papers), and providing opportunities to increase gender equity in the field.
New Paper – Sinful pleasures and pious woes? Using fMRI to examine evaluative and hedonic emotion knowledge
April 14, 2022
Traditionally, lust and pride have been considered pleasurable, yet sinful in the West. Conversely, guilt is often considered aversive, yet valuable. These emotions illustrate how evaluations about specific emotions and beliefs about their hedonic properties may often diverge. Evaluations about specific emotions may shape important aspects of emotional life (e.g., in emotion regulation, emotion experience, and acquisition of emotion concepts). Yet these evaluations are often understudied in affective neuroscience. Prior work in emotion regulation, affective experience, evaluation/attitudes, and decision-making point to anterior prefrontal areas as candidates for supporting evaluative emotion knowledge. Thus, we examined the brain areas associated with evaluative and hedonic emotion knowledge, with a focus on the anterior prefrontal cortex. Participants (N = 25) made evaluative and hedonic ratings about emotion knowledge during fMRI. We found that greater activity in the medial prefrontal cortex (mPFC), ventromedial PFC (vmPFC), and precuneus was associated with an evaluative (vs. hedonic) focus on emotion knowledge. Our results suggest that the mPFC and vmPFC, in particular, may play a role in evaluating discrete emotions.
New Paper – A computational neural model for mapping degenerative neural architectures
March 29, 2022
Degeneracy in biological systems refers to a many-to-one mapping between physical structures and their functional (including psychological) outcomes. Despite the ubiquity of the phenomenon, traditional analytical tools for modeling degeneracy in neuroscience are extremely limited. In this study, we generated synthetic datasets to describe three situations of degeneracy in fMRI data to demonstrate the limitations of the current univariate approach. We describe a novel computational approach for the analysis referred to as neural topographic factor analysis (NTFA). NTFA is designed to capture variations in neural activity across task conditions and participants. The advantage of this discovery-oriented approach is to reveal whether and how experimental trials and participants cluster into task conditions and participant groups. We applied NTFA on simulated data, revealing the appropriate degeneracy assumption in all three situations and demonstrating NTFA’s utility in uncovering degeneracy. Lastly, we discussed the importance of testing degeneracy in fMRI data and the implications of applying NTFA to do so.

New Paper – At the Neural Intersection Between Language and Emotion
March 22, 2021
What role does language play in emotion? Behavioral research shows that emotion words such as “anger” and “fear” alter emotion experience, but questions still remain about mechanism. Here, we review the neuroscience literature to examine whether neural processes associated with semantics are also involved in emotion.
Our review suggests that brain regions involved in the semantic processing of words: (i) are engaged during experiences of emotion, (ii) coordinate with brain regions involved in affect to create emotions, (iii) hold representational content for emotion, and (iv) may be necessary for constructing emotional experience. We relate these findings with respect to four theoretical relationships between language and emotion, which we refer to as “non-interactive,” “interactive,” “constitutive,” and “deterministic.
We conclude that findings are most consistent with the interactive and constitutive views with initial evidence suggestive of a constitutive view, in particular. We close with several future directions that may help test hypotheses of the constitutive view. Check out the full paper for more information.

Explaining the Panic around “Murder Hornets”
May 26, 2020
Lately, the news has been abuzz with concern about the appearance of Asian Giant Hornets, also known as “Murder Hornets,” in the US. However, murder hornets actually target bees, not humans. So why are people so afraid?
In this News at Northeastern article, Dr. Satpute explains the psychology at play. Linguistic cues in the news, contamination concerns primed by the COVID-19 pandemic, and fear of the unknown are among the factors contributing to the murder hornet panic.

New Paper – The Impact of Fear on Risk Taking
March 24, 2020
In psychological research, there is a general consensus that fear decreases risk taking. This belief influences politics, marketing, and even public health; but for years various studies have reported highly varying levels of this effect, or even a total absence of the effect.
In this paper, Sean Wake, our former lab manager, worked with Jolie Wormwood, PI of the Affective and Social Psychophysiology Lab at the University of New Hampshire, to conduct a meta-analysis using data from 50 papers, addressing a total of 136 effect sizes.
Ultimately, this research found that fear is related to decreased risk taking. However, the size of the fear’s effect on risk taking is highly variable across studies. Effect sizes are greater when studies use clinically anxious participants or when risk tasks involve tangible outcomes, but additional variance remains unexplained. Check out the full paper for more information.
New Paper – Ultra High Field fMRI of Human Superior Colliculi Activity during Affective Visual Processing, January 2020
February 12, 2020
Check out this new article in Nature’s Scientific Reports journal! Research was conducted by Candice Wang (now at Duke University for graduate school) for her senior thesis, and in collaboration with Dr. Bianciardi’s Brain Stem Imaging Lab at the Martinos Center.
The study utilized high-resolution fMRI scanning to examine activity in the superior colliculus while subjects viewed either neutral or aversive images. Aversive images elicited stronger activity in the superior colliculus, suggesting that the region contributes to the shaping of subjective emotional experience.

Deconstructing arousal into wakeful, autonomic and affective varieties
January 31, 2018
In this article, we review neuroscience findings for three of the most common origins of arousal: wakeful arousal, autonomic arousal, and affective arousal. Our review makes two overarching points. First, research conducted primarily in non-human animals underscores the importance of several subcortical nuclei that contribute to various sources of arousal, motivating the need for an integrative framework. We outline an integrative neural reference space as a key first step in developing a more systematic understanding of central nervous system contributions to arousal. Second, there is a translational gap between research on non-human animals, which emphasizes subcortical nuclei, and research on humans using non-invasive neuroimaging techniques, which focuses more on gross anatomical characterizations of cortical (e.g. network architectures including the default mode network) and subcortical structures. We forecast the importance of high-field neuroimaging in bridging this gap to examine how the various networks within the neural reference space for arousal operate across varieties of arousal-related phenomena.

Contextual Connectivity
July 26, 2017
Investigations of the human brain’s connectomic architecture have produced two alternative models: one describes the brain’s spatial structure in terms of static localized networks, and the other describes the brain’s temporal structure in terms of dynamic whole-brain states. Here, we used tools from connectivity dynamics to develop a synthesis that bridges these models. Using resting fMRI data, we investigated the assumptions undergirding current models of the human connectome. Consistent with state-based models, our results suggest that static localized networks are superordinate approximations of underlying dynamic states. Furthermore, each of these localized, dynamic connectivity states is associated with global changes in the whole-brain functional connectome. By nesting localized dynamic connectivity states within their whole-brain contexts, we demonstrate the relative temporal independence of brain networks. Our assay for functional autonomy of coordinated neural systems is broadly applicable, and our findings provide evidence of structure in temporal state dynamics that complements the well-described static spatial organization of the brain.
