2017/10/19: Lab meeting

During our weekly lab meeting I got the following feedback pertaining to project 1 (schema-memory-VR; see here): I should drop mixed condition and only use unexpected or expected locations to reduce the number of conditions. Another idea was to present objects in a sequence in order to create a temporal episode. It could be interesting in this context to look at the fragmentation hypothesis (Horner & Burgess, 2013, 2014) and see how my VR approach can be use to examine predictions of it. My idea is to create a situation that shows the predicted U-shaped relationship (see van Kesteren, Ruiter,…

2017/10/18: Lew & Howe (2016)

After examining the stimuli photos from Lew & Howe (2016),  I came to the conclusion that even schema-irrelevant objects have more or less expected locations. For instance, placing boots in the middle of the kitchen is unusual, but putting a hat on the kitchen table is less so. Reference Lew, A. R., & Howe, M. L. (2016).

2017/10/13: Lighting and 3D models

To create realistic light, set environment lighting to colour and use white. To find suitable 3D models for my virtual kitchen, I looked for models on https://archive3d.net.

2017/10/12: HPC activity and graphics in Unity

Frankland et al. (2005) reviews that HPC ripple activity is temporally correlated with cortical slow-wave spindles in the MPFC. This could be related to the integration of memories into existing schema. Unity tutorial on graphics: If I want to spawn objects at random locations, it would be problematic to pre-compute the lighting. Would it be a solution to be used mixed baking and have all the items, which do not change their location, as static because they have light maps? Use linear colour space because it is more realistic. This goes well with using HDR. When using HDR cameras, the…
