Attention:

Below are some classic attention tasks.

Change Blindness

This is a classic 'Change Blindness' Task. Measure how long it takes participants to spot the difference!

Dot Probe

The dot-probe is a classic task used to assess selective attention.

Flanker

The classic Flanker Task (or Eriksen Flanker Task), is a 'response inhibition' test used to assess participants ability to suppress responses.

Go / No-Go Task (Children)

This Inattention and Impulsivity experiment is based on a lab study conducted by Serena Bezdjian, Laura A. Baker, Dora Isabel Lozano, and Adrian Raine in 2009 on twins aged 9 and 10. Reference: Bezdjian et al. (2009)

Mackworth Clock Task

This tests vigilance, a prolonged state of concentration. Participants must stare at the image of a ticking clock and identify when the second hand jumps more than it should. This example has a jump rate of around 8% and lasts a minute, whereas a full task would jump around 0.5% of the time, and last much longer. Reference: Mackworth (1948)

Posner Cueing Task

This spatial orientation task measures the effects of cueing on reaction times to target stimuli. This example requires the participant to press one of two keys when a green 'thumbs up’ appears in the corresponding box. 75% of the time, a green circle will appear in the correct box before the stimulus appears.

Attitudes:

Below are some classic attitude tasks. To see some IAT data and analysis collected using Gorilla, see this study.

Implicit Association Tests (IAT):

IAT: 'Pictures and Pictures'

View a classic Implicit Association Test; Category sorting task, categories of images are paired with another category of interest. Differences in accuracy and RT used to potentially measure implicit bias.

IAT: 'Pictures and Words'

View a classic Implicit Association Test; Category sorting task, strength of association between categories of images and word categories. Difference in accuracy and RT used to potentially measure implicit bias.

IAT: 'Words and Words'

View a classic Implicit Association Test; Category sorting task, strength of association between two sets of word categories . Difference in accuracy and RT used to potentially measure implicit bias.

IAT: 'Age'

View a classic Implicit Association Test; compares your RT and Accuracy to categorising different aged people against positive and negative words. This is potentially a measure of implicit bias towards groups.

Other Attitude Tasks:

Semantic Priming

View a Classic semantic priming task; targets are paired with related or neutral primes. The semantic priming effect is the difference in RT and Accuracy a related prime produces.

Bot Checks:

These bot checks are designed to be easy for humans, hard for robots. Clone one or two into your experiment to make sure you're only including data from real participants!

Anagram Task

Click the scrambled letters in the right order to make a word.

Naming Task

Name the animal in the picture! Participants are presented with the silhouette of a common animal. They have to type the type of animal.

Real Effort Number Counting

Count how many zeroes appear in a grid. This is a classic real effort task. A grid of 1s and 0s is shown to the participant. They have to respond with the number of 0s. The grid is shown as an image, to make it more bot proof.

Cognition:

Below are some classic cognition tasks:

Deary-Liewald Task

This keyboard task measures response time and choice response times, which correlate with general intelligence.

Nine-dots Problem

This task is used as a measure of reasoning and the ability to 'think outside the box'. Participants are asked to connect 9 dots with four or less straight lines, without lifting the pen and without crossing the same dot more than once.

Try it out!

Relational Reasoning

This classic task assesses your ability to complete patterns across shape and colour, the participant has to choose an object to complete a puzzle display. Choose between a short demonstration version and a longer 80 trial version with varying difficulty levels.

Remote Associates Test

This task is used as a measure of creativity. Participants are given a group of 3 apparently unrelated words and must think of the 4th word which connects them.

Decision Making:

Below are some classic decision making tasks:

Delay Discount

This task assesses the relative weighting a participant puts on reward at different time periods. Will they accept a delay in receiving a reward for a greater gain.

Teen Risk Judgement

Measures a teenager's judgement of risky situations, before and after feedback on how different groups rate the risk of these situations.

Urn Task

An evidence accumulation and judgement task - the participant is repeatedly asked to reveal one of two different urns. The urn contents change with each trial and the participant has to choose the urn which most likely yields a reward.

Willingness To Pay

This task assesses how much subjects are prepared to pay for different items: This example uses snacks.

Economic Games:

Below is a classic economic game:

Prisoner's Dilemma

This is a classic experiment in Game Theory. It assesses a person's bias towards cooperating or betraying another for gain. The participant completes multiple instances, with different outcomes given - thus introducing a learning element. Reference: Wikipedia

Public Goods Game

This is a classic task in Experimental Economy. It involves a social and economic dilemma where individuals have a choice to secretly contribute some of their private funds to put into the public fund pot. These ‘public goods’ are then multiplied by the factor and distributed evenly among players. The game assesses individual’s willingness to cooperate depending on the multiplying factors. This task was created using both Task Builder and an additional script. Reference: Wikipedia

Education:

Below are some education tasks:

Comprehension

This task assesses an individual's comprehension ability when reading textual information. First a segment of text is read, then participants are asked questions assessing their understanding.

Maths Test

This type of assessment aims to quantify an individual's mathematical ability. Participants are shown different math examples in a question-answer format. They must input the correct numerical answer as quickly as possible within the timelimit.

Vocabulary Learning & Testing

Here a number of unfamiliar words are shown (French in this example), and are paired with their familiar translations. They are then tested with all words on the screen (choose the translation by clicking), and then in a free recall stage (type in the answer).
