Cologne-led paper argues that pressure changes processing complexity as well as attention
Researchers at German Sport University Cologne argue that pressure changes how complex information processing is, not only where attention goes. The idea would explain why the same pressure makes one person choke and another excel.

What happened
- Attention accounts help explain why performance deteriorates under pressure but are less complete on why some people perform exceptionally well.
- The authors describe simpler processing as combining fewer pieces of information or controlling a movement as one unit, and complex processing as combining many pieces or controlling components separately.
- They call the target "task-matched complexity", a level of processing matched to both the task and the individual, and say pressure can alter that balance.
- The article is theoretical. It draws together existing empirical findings, and its predictions still need to be tested.
Why it matters
- What it limits constraint Blanket advice to athletes to think less, or to take in as much information as possible, has no support in this framework, because neither direction is better by itself.
- Who has to decide decision Anyone testing the idea has to measure how well a person's processing rule fits the task independently of the result, or simplifying and adding complexity can each explain any outcome.
- What's now possible capability If the predictions hold up, studies of pressure could ask which form of processing helps in a given situation, and not only why performance breaks down.
A penalty kick shows how the framework is meant to work. A player may rely on one piece of information from the coach. A more complex rule would integrate several, such as the goalkeeper's position, movement and known tendencies [6]. Either can be right.
"Neither simplification nor complexity is automatically better. What matters is whether the way information is processed fits the task and can be implemented reliably by the individual," said Dr. Laura Voigt, principal investigator of the project at the German Sport University Cologne [4][5].
Fit is what separates the outcomes. Simplifying helps if the person had been processing unnecessary information, and hurts if relevant information is discarded. Adding complexity helps when more information is needed, and hurts when it brings in unnecessary or hard-to-implement steps [8]. Pressure moves a person along that scale. Whether the move is a rescue or a failure depends on where the person started and what the task demands.
In our view, this is the right question to ask, and probably a hard one to answer. A framework in which both simplifying and adding complexity can help or hurt can absorb any result, unless the fit between a person's rule and the task is measured separately from how the person performed. The thing this doesn't tell you is how to take that measurement. The university's release does not describe a measure of processing complexity.
Until someone builds one, the paper's predictions cannot fail, and so cannot yet be confirmed either.
What to watch
- Empirical tests that measure processing complexity separately from performance, in athletes or in lab tasks.
- Training studies that compare general instructions such as "think less" with guidance matched to the task.

Researchers from the German Sport University Cologne, with colleagues from New Zealand, published the article "Beyond attention: Performance pressure shifts information-processing complexity" in Trends in Cognitive Sciences.

The authors argue that under pressure, changes may occur not only in which information receives attention but also in how that information is processed, integrated and translated into action.
- [3]
Under the proposal, people may process information by simpler rules, such as combining fewer pieces of information or controlling a movement as one integrated unit. Processing may become more complex when multiple pieces of information are combined or individual movement components are controlled separately. Neither form is inherently better.

In a penalty kick, a player may rely on one piece of information provided by the coach, while a more complex decision rule may integrate several sources of information, such as the goalkeeper's position, movement and known tendencies.

The researchers use the term "task-matched complexity" for a level of information-processing complexity that is well matched to both the task and the individual. Pressure can alter this balance.
- [8]
Simplification may help when a person was previously processing unnecessary information, but can be detrimental if relevant information is discarded. More complex processing can be beneficial when additional information is needed, but may impair performance if it introduces unnecessary or difficult-to-implement processing steps.
- [9]
The publication is a theoretical article. The authors bring together existing empirical findings and theoretical perspectives, and the predictions derived from the perspective now need to be tested empirically.
- [10]
Attention-based accounts help explain why performance deteriorates under pressure, but give a less complete explanation of why people sometimes perform exceptionally well.
- [11]
The framework offers a possible explanation for why both choking, a drop in performance under pressure, and exceptionally good performance may arise from changes in the same underlying process.
- [12]
Instead of generally advising athletes to "think less" under pressure or to consider as much information as possible, future research could focus on which form of information processing is helpful in a given situation.
- [13]
Voigt said the approach makes it possible to investigate not only why performance breaks down under pressure but also which forms of information processing may help people access their potential when it matters most.
