ABSTRACT From navigating a crowded hallway to skiing down a treacherous hill, humans are constantly making decisions while moving. Insightful past work has provided a glimpse of decision deliberation at the moment of movement onset. Yet it is unknown whether ongoing deliberation can be expressed during movement, following movement onset and prior to any decision. Here we tested the idea that an ongoing deliberation continually influences motor processes—prior to a decision—directing online movements. Over three experiments, we manipulated evidence to influence deliberation during movement. The deliberation process was manipulated by having participants observe evidence in the form of tokens that moved into a left or right target. Supporting our hypothesis we found that lateral hand movements reflected deliberation, prior to a decision. We also found that a deliberation urgency signal, which more heavily weighs later evidence, was fundamental to predicting decisions and explains past movement behaviour in a new light. Our paradigm promotes the expression of ongoing deliberation through movement, providing a powerful new window into understanding the interplay between decision and action.more » « less

null (Ed.)The most important impacts of social movements are often cultural, but the sheer variety of potential cultural impacts—from shifts in public opinion to new portrayals of a group on television to the metrics guiding funding in a federal agency—presents unique challenges to scholars. Rather than treating culture as a social sphere separate from politics and the economy, we conceptualize it as the ideas, values, and assumptions underpinning policies and practices in all spheres. We review recent research on movements’ impacts on public opinion and everyday behavior; the media and popular culture; nonpolitical institutions such as science, medicine, and education; and politics. We focus on cultural impacts that have mattered for movements’ constituencies and address why movements have had those impacts. We conclude with an agenda for future research, seeking greater connection between the literatures on movements and the literatures on the institutions that matter to movements.more » « less

Humans can recognize their whole-body movements even when displayed as dynamic dot patterns. The sparse depiction of whole-body movements, coupled with a lack of visual experience watching ourselves in the world, has long implicated nonvisual mechanisms to self-action recognition. Using general linear modeling and multivariate analyses on human brain imaging data from male and female participants, we aimed to identify the neural systems for this ability. First, we found that cortical areas linked to motor processes, including frontoparietal and primary somatomotor cortices, exhibit greater engagement and functional connectivity when recognizing self-generated versus other-generated actions. Next, we show that these regions encode self-identity based on motor familiarity, even after regressing out idiosyncratic visual cues using multiple regression representational similarity analysis. Last, we found the reverse pattern for unfamiliar individuals: encoding localized to occipitotemporal visual regions. These findings suggest that self-awareness from actions emerges from the interplay of motor and visual processes.more » « less
