Sustained Attention to Response Time Task (SART)

This SART task is modeled on the framework used in The Irish Longitudinal Study on Ageing (TILDA)

Participants must press a button (mouse or onscreen) in response to a series of digits and withold responses on the number 3)

Each digit appears for 300ms, with an interval of 800ms between digits. The cycle of digits 1–9 is repeated 23 times, giving a total of 207 trials. The task lasts approximately for 4min

A forward and Backward Digit Span test for Working Memory The test adapts to participnts' answers and a score is calculated following Woods et al. (2012)

In this task participants are required to memorise and recall number series in order. Participants start out with three 3-digit sequences. If participants correctly recall 2 out of 3 three sequences, they progress to 4-digit sequence trials and so on. If participants respond incorrectly on 2/3 trials the experiment terminantes. This experiment is based on the original digit span experiment by Jacobs (1887).

This is an update to Topor’s implementation of the PST by Frank, Woroch and Curran (2005), made to run online. See https://doi.org/10.1016/j.brs.2022.02.009 for details of other modifications made for offline version and carried through to here.

The aim of this study is to determine whether likeability ratings of novel food images will decrease after these images are paired together with obese, normal, thin body shapes. If you participate, you will be asked to rate a number of novel food stimuli on how much you think you would like them on a Likert scale from -100 (extremely dislike) to +100 (extremely like). You will then be shown these novel food items again, but each one will also be immediately be followed by an image of different body types (obese, normal, thin). An extinction phase will also be conducted where certain food and body image pairings will not be shown, and the food image will be shown without a body image being shown immediately after. Following these conditioning and extinction phases, you will then be asked to rate both the novel food images and body images using the same Likert scale which will show if your likeability rates differ after viewing the food images being paired with different body types.

In this task participants are required to judge which line is longer than the other. This experiment is based on illusion devised by Franz Carl Müller-Lyer in 1889.
