ChatGPT is trying to tell me that Wolverine was an original member of the X-men. Looks like I still have a purpose.

I miss twitter.

The original:

For those of you who have been teaching for longer than I have: when a student asks if the exam will be difficult is there anything to say other than 'hell yeah'?.

Also, I should mention, when I say “our” I mean me and Dr. Shomstein (@GWUAttentionCo1).

Ta-daaa! (12/11).

Overall, this suggests a mechanism for semantic knowledge influencing perception. (11/11).

We also found that these differences disappeared when we turned the object images upside-down, making them harder to recognize, and they were modulated by presenting the objects on a red background, which inhibits the magnocellular pathway. (10/11).

The flickers weren’t more easily detected on tools like we predicted (d’ was the same across tools and non-tools), but the flickers were more quickly reported when presented on a tool object in a discrimination instead of a detection task. (9/11)

Across a few experiments (one was a replication with more realistic images!), participants were better at seeing the missing chunks on non-tools than on tools! (8/11)

The second task, instead of the flicker the objects could be missing a small chunk. We predicted that if non-tools have higher spatial resolution than the participants should be better at noticing the missing chunk on non-tools than on tools. (7/11)

We used two tasks, each one presenting line drawings of tools or non-tools. In one, the object could flicker. We predicted that if tools are perceived faster then our participants should be better at detecting the flickers on the tools. (6/11)

We reasoned that because tools elicit more dorsal stream activity, and the dorsal stream is faster, then tools would be perceived faster than non-tools. Conversely, we reasoned that non-tools would be perceived with higher spatial resolution than tools. (5/11).

Also, the dorsal and ventral streams differ in input by the magno- and parvo-cellular pathways. The dorsal stream has more magnocellular input, so it's faster, and the ventral stream has more parvocellular input, so it’s better at details. (4/11).

A difference between these two groups, at least neurally, is that tools generate a larger amount of activity than the non-tools in the parietal, the so called ‘how/where’ dorsal stream, leaving the non-tools stuck with the ventral ‘what’ stream in the temporal lobe. (3/11).

We were interested in how object semantic knowledge might influence perception. We looked at manipulable objects (or ‘tools’ for character count; these included things like hammers and the eponymous mug) and non-manipulable objects (ahem, non-tools, like a potted plant). (2/11)

Well, our paper was published in psych science recently. We think it’s pretty neat, so here’s a thread on it. (1/11).

The 2020 we got was not nearly as cool as the one in Reign of Fire. I'll take a mulligan.
