Broca’s Area Is Not a Natural Kind
Publication date: Available online 20 February 2020Source: Trends in Cognitive SciencesAuthor(s): Evelina Fedorenko, Idan A. BlankTheories of human cognition prominently feature 'Broca’s area', which causally contributes to a myriad of mental functions. However, Broca’s area is not a monolithic, multipurpose unit – it is structurally and functionally heterogeneous. Some functions engaging (subsets of) this area share neurocognitive resources, whereas others rely on separable circuits. A decade of converging evidence has now illuminated a fundamental distinction between two subregions of Broca’s area that likely pla...

Digital Emotion Contagion
This article reviews the growing literature on digital emotion contagion. After defining emotion contagion, we suggest that one unique feature of digital emotion contagion is that it is mediated by digital media platforms that are motivated to upregulate user emotions. We then turn to measurement, and consider the challenges of demonstrating that digital emotion contagion has occurred, and how these challenges have been addressed. Finally, we call for a greater focus on understanding when emotion contagion effects are likely to be strong versus weak or nonexistent. (Source: Trends in Cognitive Sciences)

Why Are Self-Report and Behavioral Measures Weakly Correlated?
Publication date: Available online 17 February 2020Source: Trends in Cognitive SciencesAuthor(s): Junhua Dang, Kevin M. King, Michael InzlichtAccumulating evidence indicates weak correlations between self-report and behavioral measures of the same construct. We suggest that these weak correlations result from the poor reliability of many behavioral measures and the distinct response processes involved in the two measurement types. We also describe how researchers can benefit from appropriate use of these measures. (Source: Trends in Cognitive Sciences)

Overarching States of Mind
Publication date: Available online 6 February 2020Source: Trends in Cognitive SciencesAuthor(s): Noa Herz, Shira Baror, Moshe BarWe all have our varying mental emphases, inclinations, and biases. These individual dispositions are dynamic in that they can change over time and context. We propose that these changing states of mind (SoMs) are holistic in that they exert all-encompassing and coordinated effects simultaneously on our perception, attention, thought, affect, and behavior. Given the breadth of their reach, understanding how SoMs operate is essential. We provide evidence and a framework for the concept of SoM, and ...

Space, Time, and Fear: Survival Computations along Defensive Circuits
Publication date: Available online 3 February 2020Source: Trends in Cognitive SciencesAuthor(s): Dean Mobbs, Drew B. Headley, Weilun Ding, Peter DayanNaturalistic observations show that decisions to avoid or escape predators occur at different spatiotemporal scales and that they are supported by different computations and neural circuits. At their extremes, proximal threats are addressed by a limited repertoire of reflexive and myopic actions, reflecting reduced decision and state spaces and model-free (MF) architectures. Conversely, distal threats allow increased information processing supported by model-based (MB) operat...

Theta Oscillations in Human Memory
Publication date: Available online 3 February 2020Source: Trends in Cognitive SciencesAuthor(s): Nora A. Herweg, Ethan A. Solomon, Michael J. KahanaTheta frequency (4–8 Hz) fluctuations of the local field potential have long been implicated in learning and memory. Human studies of episodic memory, however, have provided mixed evidence for theta’s role in successful learning and remembering. Re-evaluating these conflicting findings leads us to conclude that: (i) successful memory is associated both with increased narrow-band theta oscillations and a broad-band tilt of the power spectrum; (ii) theta oscillations specific...

Reevaluating the Role of Persistent Neural Activity in Short-Term Memory
Publication date: Available online 29 January 2020Source: Trends in Cognitive SciencesAuthor(s): Nicolas Y. Masse, Matthew C. Rosen, David J. FreedmanA traditional view of short-term working memory (STM) is that task-relevant information is maintained ‘online’ in persistent spiking activity. However, recent experimental and modeling studies have begun to question this long-held belief. In this review, we discuss new evidence demonstrating that information can be ‘silently’ maintained via short-term synaptic plasticity (STSP) without the need for persistent activity. We discuss how the neural mechanisms underlying S...
