Moving arms: the effects of sensorimotor information on the problem-solving process

Embodied cognition postulates a bi-directional link between the human body and its cognitive functions. Whether this holds for higher cognitive functions such as problem solving is unknown. We predicted that arm movement manipulations performed by the participants could affect the problem-solving solutions. We tested this prediction in quantitative reasoning tasks that allowed two solutions to each problem (addition or subtraction). In two studies with healthy adults (N?=?53 and N?=?50), we found an effect of problem-congruent movements on problem solutions. Consistent with embodied cognition, sensorimotor information gained via right or left arm movements affects the solution in different types of problem-solving tasks.     

Motivation and self‐regulation: The role of want‐to motivation in the processes underlying self‐regulation and self‐control

Research on self‐regulation has largely focused on the idea of effortful self‐control, which assumes that exerting willpower will lead to greater success. However, in recent years, research has challenged this perspective and instead proposes that effortless self‐regulation is more adaptive for long‐term goal pursuit. Taking into consideration the burgeoning literature on effortless self‐regulation, here we propose that motivation—or the reasons why we pursue our goals—plays an integral role in this process. The objective of the present paper is to highlight how motivation can play a role in how self‐regulation unfolds. Specifically, we propose that pursuing goals because you want‐to (vs. have‐to) is associated with better goal attainment as a function of experiencing less temptations and obstacles. While the reason why want‐to motivation relates to experiencing fewer obstacles has yet to be thoroughly explored, here we propose some potential mechanisms drawing from recent research on self‐regulation. We also provide recommendations for future research, highlighting the importance of considering motivation in the study of self‐regulatory processes.     

How Fragile Is Conditional Cooperation? A Field Experiment with Smartphones during the 2014 Soccer World Cup

We conducted an experiment in a highly cooperative environment to find out how a disruption, similar to a broken window, affects behavior. A centipede game was framed as a game of soccer and run with smartphones during a soccer public viewing event, that is, a Bavarian beer garden with a large screen displaying a soccer game. We provided some subjects with information that was supportive to cooperation and others with disruptive information, aimed at inducing a broken window effect. The disruption reduced the willingness to cooperate at the final stage of the game. But expectations regarding teammates remained unaffected such that cooperation at earlier stages remained high. Cooperation is thus not as fragile as one might fear. Copyright © 2016 John Wiley & Sons, Ltd.     

Seeing what we know and understand: How knowledge shapes perception

Expertise in object recognition, as in bird watching or X-ray specialization, is based on extensive perceptual experience and in-depth semantic knowledge. Although it has been shown that rich perceptual experience shapes elementary perception and higher level discrimination and identification, little is known about the influence of in-depth semantic knowledge on object perception and identification. By means of recording event-related brain potentials (ERPs), we show that the amount of knowledge acquired about initially unfamiliar objects modulates visual ERP components already 120 msec after object presentation, and causes gradual variations of activity in similar brain systems within a later timeframe commonly associated with meaning access. When perceptual analysis is made more difficult by blurring object pictures, knowledge has an even stronger effect on perceptual analysis and facilitates recognition. These findings demonstrate that in-depth knowledge not only affects involuntary semantic memory access, but also shapes perception by penetrating early visual processes traditionally held to be immune to such influences.     

Offside decisions by expert assistant referees in association football: Perception and recall of spatial positions in complex dynamic events

This study investigated the offside decision-making process in association football. The first aim was to capture the specific offside decision-making skills in complex dynamic events. Second, we analyzed the type of errors to investigate the factors leading to incorrect decisions. Fédération Internationale de Football Association (FIFA; n = 29) and Belgian elite (n = 28) assistant referees (ARs) assessed 64 computer-based offside situations. First, an expertise effect was found. The FIFA ARs assessed the trials more accurately than the Belgian ARs (76.4% vs. 67.5%). Second, regarding the type of error, all ARs clearly tended to raise their flag in doubtful situations. This observation could be explained by a perceptual bias associated with the flash-lag effect. Specifically, attackers were perceived ahead of their actual positions, and this tendency was stronger for the Belgian than for the FIFA ARs (11.0 vs. 8.4 pixels), in particular when the difficulty of the trials increased. Further experimentation is needed to examine whether video- and computer-based decision-making training is effective in improving the decision-making skills of ARs during the game.
