comment Why do dreams lose clarity quickly over time after we awaken?
In case I don't manage to find the time to dig up the reference (I have it somewhere on an external disk, no idea who the authors are): a neurotransmitter that is crucial for transforming short-term into long-term memories is inactive in the hippocampus during sleep. Interestingly, HM, a patient who couldn't achieve long-term memories due to an operation when both hippocampi were removed, described his state as constantly waking from a dream.

comment Diffrence between SSVEP and P300
Interesting stuff! I have indeed also come across some papers where the steady-state response is modulated by top-down factors, so it appears not to be purely stimulus-driven. And a lot of new research shows attention and expectation modulation of sensory components that are quite early. I just have the impression that the consensus is that these modulations are surprising for the SSVEP/AEP, while they are a given for the P3. In fact I don't even know if there is any discernible P3 component in the absence of top-down effects?

comment How does the frequency of a visual stimulus affect the steady-state visually evoked potential?
The refresh rate is the rate at which the image on your screen gets renewed. I think that for most monitors it's 60 Hz. But it's often more complicated than that, because screens often don't refresh the entire image at once (e.g. they might do it line by line, or odd vs. even lines, or center to surround). But some of this flicker would probably be visible in the neural response. I'm not too sure about that though, maybe it's too subtle to be registered as neural activity.

comment How does the frequency of a visual stimulus affect the steady-state visually evoked potential?
By amplitude modulation I mean this. In this picture the carrier signal is the frequency of the tone, whereas the modulating sine wave signal is what I call amplitude modulation. The result is an amplitude modulated signal: it's a tone of a given pitch, that gets louder and softer at the frequency of the modulating sine wave signal. This frequency should also be visible in the neural response.

comment How do laypeople form a judgement that another person is smart or intelligent?
I don't have a reference because I heard it in class long ago, but the professor of the course on intelligence told us that people are fairly accurate (whatever that means) in assessing other people's intelligence - if it's lower or similar to theirs. But they can't make fine grained judgments about people who are more intelligent.

revised What factors affect the g factor?
added 'interpersonal differences' to highlight that these factors are linked to variations in intelligence.

comment How to get more involved with personality psychology as a hobby?
Also, social psychology has a lot to say on why people behave the way they do. The difference is that it talks about general tendencies in behaviour, while personality psychology goes into the differences between individuals, as well as how they self-reflect.

comment How to get more involved with personality psychology as a hobby?
Just a small tip for searching for literature: personality psych also goes under the name of psychology of individual differences, as well as (less often) differential psychology.

comment Difficulty of having profound scientific discussions with more than 2 or 3 people?
I love this question. I've been thinking about the same thing lately (how to get the best discussions out of a large, diverse group of students) and my intuition is also that a small group of people on a similar level works best.
