2018/10/18: Finalising analysis and design

What have I been doing all the time? It has been a while since the last post on this blog. The major reason for this is that I was busy preparing the next experiment (schemaVR3) and planning the next project. Conerning schemaVR3: Its aim is to corrobrate the evidence that recollection and familiarity are differently involved in the memory of advantage for unexpected and expected locations. Hopefully, I will be able to start collecting data for this experiment on the 29th of October. I selected five suitble sets for schemaVR3 (here) and made sure that spread of those sets is…

2018/08/01: Final analysis, design of third experiment and plans for future

I am finally back in my office after a short holiday and after doing some teaching. I am glad to announce that I submitted my first year report and successfully defended it. That is the reason why, I haven’t posted anything in a while, but as soon as I do more work again, that can be uploaded, I will do that. The results reported in my first year report are very promising. They show that there is a reliable U-shaped relationship between object/location expectancy and memory performance. Further analysis (link) among other things showed that this is also the case…

2018/06/08: Psychology and Brain 2018 in Gießen and new ideas

Psychology and Brain Last weekend, I went to Psychology and Brain conference, which was really interesting and an inspiration for a couple of new projects. First of all, I was really pleased that there was a symposium on VR in biological psychology. On that symposium, Johannes Fuß among others presented work attempting to bridge the gap between animal and human research, which inspired me to think about a human version of the task used in Tse et al. (2007) using immersive VR. During the conference, I also saw the need to organise a community and foster exchange among cognitive neuroscientist…

2018/05/02: End of schemaVR1 and start of schemaVR2

Today, I finished the data collection for schemaVR1. I collected 17 instead of 16 participants because I wanted to show the experiment to someone who then agreed to formally take part in this experiment. The two major the results of this experiment are that the locations of objects that are generally unexpected in a kitchen are remembered better (measured by 3D location recall and 3AFC location recognition) than the locations of objects that are expected in a kitchen. This can already be seen in the interim analysis (N = 9) that I uploaded here. The second result, which was only…

2018/04/12: Interim results and future plans

I am currently caught up with collecting data for my first experiment, which I will henceforth call schemaVR1, working on my first year report and analysing the interim results. I have collected data from eight participant so far and already got number of significant results. This is quite impressive considering that I also have only twenty stimuli/trials. I will upload the pre-processing script alongside a script analysing the interim results in the next days in a separate GitHub repository, where I will provide more details, but a very robust, and already significant, finding is that the locations of unexpected objects…

2018/02/14: Final design of project 1

My supervisor and I agreed on the final design while discussing the results of the pilot experiment. We both think that it is important to replicate Lew & Howe (2016) results if their test is used, but not if one uses 3AFC test. They used a Y/N location recognition task (“Was this object in this place before?”) and location recall task (2D picture version). I will develop a spatial 3D location recall task for the VR system to replicate the results in the first experiment. I will also use a 3AFC test to show that it is bias at retrieval…

2018/02/13: Final analysis of pilot data

I just finished analysing the pilot data. The next step will be to improve the experimental protocol, some small issues about the graphics of the VE and creating the final analysis script. Link to RMarkdown file
