Mixed effects models are a great tool to learn about. I don't have enough time to go into a lot of detail in this video so have a read of these useful links by Michael Clark and Coding Club.

In this video, I build an n-armed bandit task in Gorilla Task Builder. Participants will choose between a blue and green slot machine in order to win the most points. Each slot machine has a different probability of paying out, as well as a different number of points available. The probilities and points are driven by a spreadsheet. At the end of the video, I used a little bit of scripting to calcalate who's a winner and what the total score is.

In this video, we'll use the hBayesDM package in R Studio to calculate the learning rate for each participant. We'll also calculate scores for winning trials along with the total scores for stable and volatile periods.
If you're interested in learning more about computational modelling of beahaviour there are some great online resources including this page by Drs den Ouden and O'Reilly.
I would strongly recommend going to this page for a course run by Miriam Klein-Flügge, Jacqueline Scholl, Laurence Hunt, and Nils Kolling from Oxford University where they discuss modelling a variation of this exact task.

In this video, we'll use paired T-tests, repeated measures ANOVAs, and correlations to explore this dataset. We'll also look at assumptions and how results change when you use the correct assumptions. All the analyses are conducted in JASP.

This video will introduce some of the different types of social influence, inlcuding: conformity, obedience, social learning, nudging, framing, and contagion.
In this lecture, I also made reference to the Stirling University's Nudge database. Click on this link to see lots of real world examples of nudging

In this video, I build a novel social influence task. Participants rated a series of movies using sliders, after which they learnt what the critics and audience thought and make a second rating. This video shows you how to use branching and embedded data, as well as a bit of scripting to change an attribute (move slider tip to participants previous rating).
Although there isn't a task out there like this, a lot of inspiration was drawn from De Martino et al (2017), you can read the full manuscript here.

I was incredibly honoured to have one of my mentors and creator of the SART, Professor Ian Robertson, tell me all about Sustained Attention, the creation of the SART, and how to use this amazing tool effectively.

In this video, I build the fixed and random Sustained Attention to Response Tasks as described in Robertson et al (1997).
Participants will see a series of digits (1-9) in a fixed or random order. Participants were required to respond whenever a number came on screen, unless it was a 3. Being able to snap out of a routine rhythmic patterns is a hallmark of sustained attention. Building this task required using different content types, encoding keyboard responses, using screen time limits, and different spreadsheet randomistion rules. There's even a bit of scripting to randomly change the size of the numbers on each trial.

In this video, we pivot tables in excel to preprocessing the data. We also use filters in excel to diagnose some crazy values in our data. Later, we'll use correlations, a one way ANOVA, and a repeated measures ANOVA to address our hypotheses.
All the analyses are conducted in JASP.

In this video, I'll show you how to preprocess your data in R Studio using some basic dplyr functions. In R Studio I was able to easily deal with the double tap problem mentioned here.
I'll also show you some simple and powerful analyses using ggstatsplot. It's a wonderful tool that covers pretty much every type of analysis, combining beautiful plots with detailed stats.
