This experiment is designed to measure participants' forwards, backwards, and sequential digit spans. It uses visual presentation. Sequence length increases every two trials. If participants make an error on both trials of the same length, they move onto the next trial.

Psychomotor Vigilance Task to be run in Pavlovia

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).

Dot-probe task with nicotine images, the following project includes two type of nicotine stimuli: primary stimuli and secondary stimuli, each one containing a total of 12 pair of images repeated 4 times in a random way (48 trials per stimuli type). Between the primary and secondary stimuli there is a 2 minutes pause to let the subject recover its attention. There is a random loop to allow the primary and secondary stimuli to always be selected in a different random order

This task shows you the drag and drop capabilities of PsychoPy and PsychoJS. The demonstration uses a drag and drop puzzle game. The task requires you to drag and drop the black and white pieces into the empty square.

Go/no-go task based on Redick et al.’s (2011) article “Working Memory Capacity and Go/No-Go Task Performance: Selective Effects of Updating, Maintenance, and Inhibition”.

Recognition memory task - encoding and retrieval tasks with 10 min delay period between tasks

A simple demo of audiovisual temporal adaptation. Participants are presented with sets of flash-beep pairs. In the adaptation block participants passively watch the stimuli. In the respond block participants judge if the beep or flash was presented first.

Sensory adaptation occurs when participants judgements are shifted by a period of training (e.g. first presenting stimuli with an audio-lead lag may later bias participants to respond that they heard the beep first)
