Where to publish Decision Making research

Some of my research has taken (and will continue to take) a decision making approach to low-level tasks in visual perception and visual attention. Recently however I have been working on some higher level decision making tasks and so I’ve been scoping out target journals and conferences. In this post I provide a brief list of suitable journals. […]

Cognitive modelling 3: the importance of a script

One of the key things we must avoid is mess and confusion. In the last post I briefly covered one possible template for a research project. One of the reasons why cognitive modelling projects might be a little tricky is because you are not just using an off the shelf software package. For example, if […]

Cognitive modelling 2: project structure

What we definitely want to do is avoid confusion and mess. Having a clear project structure and workflow has many advantages. While there is no one single correct way to organise a project, putting a bit of thought into it, and learning from past projects can help a lot. This is the workflow that works for […]

Cognitive modelling 1: programming problems

This is the first post in a series exploring programming practice in cognitive modelling. While I have over a decade of experience in cognitive modelling, I am in no way an expert and have no formal computer science training. I am not an authority on this, I am feeling my way. Comments welcome. This post may […]

Plotting posterior predictive distributions

I’ve just released a small bit of Matlab code on GitHub which helps automate the job of plotting posterior predictive distributions. If you are inferring posterior distributions of parameters of a 1D function (e.g. y=mx+c) then this code will plot the posterior predictive distribution for you. This should be handy for you to eyeball how well a model […]

Sate the urge to draw a graph: useful software

Sometimes one just has the urge to draw a graph, and to draw a graph quickly. This happens to me when I’m trying to convey basic ideas either in my teaching material or for the introduction of a talk, for example. In the past I have tried the approach of copy/paste from Google Images or by searching through my paper […]

Metabolic income inequality in the human body

We’ve been hearing a lot about society’s inequality in terms of wealth and income recently. Many statistics are quoted along the lines of “Britain’s top 1% own as much as the bottom 55%.” This made me think back to my DPhil work, where one of the key factoids constantly in my mind was the disproportionately demanding nature […]

Public talk at Dundee Skeptics in The Pub

Earlier this week I had a nice opportunity to talk about epistemology and inference to the Dundee Skeptics in The Pub. The talk seems to have been well received and a lively discussion followed. I took the chance to correct the misunderstanding that Sherlock Holmes is a master of deductive inference, using this amusing video.

It is Time to Stop Teaching Frequentism to Non-statisticians

Great stuff, from William M. Briggs […] there are lot of folks out there who, because they once had a graduate survey course in regression, and have personally produced a p-value or two, feel they are versed sufficiently in probability to pass on their skills to fresh students. But their rendering of the subtleties of […]

Learning Python? Watch these videos…

Enthought have put together a very comprehensive set of training videos on how to program in Python. If you are a student or faculty, then you can register for their free academic account and get access to the videos. Highly recommended. https://enthought.com/services/training/python-training-on-demand

Software for MCMC

If you’ve decided to join the increasing number of people using MCMC methods to conduct Bayesian inference, then one important decision is which software to use. This decision will be influenced by your programming language of choice, see Figure below. If you use Matlab, then really your best choice at the moment is JAGS. You use it […]

How many papers do academics publish each year?

Gringras et al (2008) provide an answer in their examination of how publication rates and citation habits vary over the lifespan. They gathered publication and citation data for >14,000 professors between 2000 and 2007. One possible limitation of their analysis is that they examine data from multiple domains (natural sciences, medicine, social science and humanities) […]

5 min videos as grant applications?

This month, there was a suggestion that grant funding should be achieved by a 5 minute video pitch.  Here is their (closed-access) paper: http://dx.doi.org/10.1016/j.tibs.2014.01.004 But it’s nice to see that they walk the talk and have made a video summarising their paper. Although, nobody uses the world multimedia any more (data from Google Ngram viewer) Their key […]

Start coding. Do it.

This is not a fair, even-handed review of all possible languages for all purposes. The intended audience is undergraduate psychology students who cannot code. What is coding? Why learn to code? Excellent arguments are made in this person’s blog post “Why every (psychology) student should learn to code“. The main points are: If you want […]
