What is the Semantic Switching?
Semantic Switching is a form of cued task switching in which the rules are about meaning. A word appears, and a cue tells you which question to answer about it, for example whether it is a living thing or whether it is bigger than a shoebox. The same word can need a different answer depending on the question, so you cannot settle into one way of thinking about it.
In the laboratory, cued task switching is used to study cognitive flexibility, usually by measuring the switch cost: the extra time needed when the question changes. When the questions concern word meanings, the task also relies on semantic memory, our store of knowledge about words and concepts. The Neuroptimize Semantic Switching game presents a stream of everyday words, with a coloured question that switches without warning.
How to play the Semantic Switching
- A word such as "piano" appears on a card. Above it, a coloured cue asks a question, such as "Living or not?" (green) or "Bigger than a shoebox?" (blue).
- Answer with one of the two buttons below the word, or use the left and right arrow keys (A and D, or F and J, also work). The button labels change with the question, for example Living and Not living, or Bigger and Smaller.
- A wrong answer breaks your combo, and the next word appears straight away. You have 60 seconds, and the results show your average reaction time and your switch cost.
- At low levels there are two questions. From level 10 a third joins them: "Natural or man-made?" (orange). The question switches more often as the level rises.
- Below level 18 a "Switch!" badge flags every change of question. From level 18 the badge is gone and only the cue text and colour change.
- Normally the "yes" answer, such as Living, Bigger or Natural, is on the left. From level 20 the two answers can swap sides on any word, so you have to read the buttons.
Strategies and tips
Read the colour before the word
The cue colour tells you the question at a glance: green for living, blue for size, orange for natural or man-made. Registering it first stops you from answering the question you had on the previous word.
Anchor answers to the left
Until level 20, the "yes" answer is always on the left and the "no" answer on the right. Thinking in terms of yes and no, rather than reading the labels, saves time on every word.
Settle the tricky categories
Some words need a moment: plants such as a daisy or a mushroom count as living, clouds and icebergs count as natural and bigger than a shoebox, and a bicycle counts as bigger. Deciding these in advance avoids hesitation mid-game.
Expect a switch at any time
The question changes at random, and at higher levels most words bring a new one. Treat every word as a fresh question instead of assuming the last rule still holds.
Read the buttons from level 20
Once the answers can swap sides, the left and right positions no longer mean yes and no. Glance at the labels before you tap, even if it costs a fraction of a second.
The science behind the Semantic Switching
In cued task switching, a cue indicates which of two rules applies on each trial. When the rules concern the meanings of words, the task also draws on semantic memory, the store of general knowledge about words and concepts, and on the ability to retrieve that knowledge flexibly.
Frequently asked questions
What is cued task switching?
Cued task switching is an experimental design in which a cue on each trial tells the participant which of two or more tasks to perform. Because the cue can change at any time, people have to keep checking it and adjust their response rule. Performance on switch trials is compared with performance on repeat trials.
What is semantic memory?
Semantic memory is the part of long-term memory that holds general knowledge, such as facts, word meanings and concepts. Knowing that a whale is alive and larger than a shoebox draws on semantic memory. It is usually contrasted with episodic memory, which stores personal experiences.
Why does changing the question slow people down?
Answering one question about a word sets up a way of thinking about it. When the question changes, that setting has to be replaced before the new question can be answered, which usually costs time. This extra time is the switch cost that Neuroptimize reports at the end of each session.
Is the Semantic Switching game free?
Semantic Switching is a Pro game in Neuroptimize, and Pro starts with a 7-day free trial. Free players can also get it as the Pro game of the day in their daily workout.
