Short answer is YES, at least for rats, who do have chemosensors in their brain and alter their liking of salty foods and foods containing certain amino acids. See this question and question on Biology.SE: Do humans have chemosensors for nutrients or chemicals? Do omnivore mammals vary food preferences based on dietary needs?

I think this question may be better asked at biology.SE. I have to cite popular science press here, but nevertheless, clearly the answer seems to be: no. Scientific American: Peter Pressman of the Cedars Sinai Medical Center in Beverly Hills, Calif. and Roger Clemens of the University of Southern California School of Pharmacy explain. Food craving, ...

The answer is more involved than it seems. Expertise research programmes, including Ericsson's line, has tended to blend quantitative and qualitative research methods (e.g., case studies, talk-aloud protocol, etc.), and there is a veritable host of critiques and qualifications that apply. For the scope of this answer, I will therefore try to err on the side ...

There has been a lot of research into this topic in the recent years. My understanding is influenced by the following : 1. The Talent Code by Daniel Coyle. 2. Mastery by Robert Greene. 3. The Mundanity of Excellence.4. Why Skills trump Passion by Cal Newport. The best thing for you to do would be to read these for yourself. CHOOSE THE CHALLENGE : This ...

Of course, if you try to learn a new language, you should start to learn the basics. Maybe it's good to buy a book for the topic. Structure the knowledge It's important to have an overview because you must know what you should learn. Maybe you can create a mindmap which is very effective. Look here: http://en.wikipedia.org/wiki/Mind_map#Research Use the ...

Cognitive Architectures The description most closely matches the concept of a cognitive architecture. Whereas I would say most empirical cognitive science focuses on isolating cognitive functions or behavioral substrates, cognitive architectures are relatively unique because they attempt to run bottom-up simulations of interdependent sets of cognitive ...

I'm not sure how helpful my answer will be, but I get my "news" from scanning journals related to my interests. I look through 1) broad review journals, 2) broad empirical journals and 3) more specific empirical journals. In general, I find that popular media outlets do a poor job of reporting on research in psychology/neuroscience (but hopefully someone ...

Heritability is the proportion of differences in some observable trait (e.g., intelligence, height, love for pizza) in a population that can be attributed to genetic influences. Heritability is estimated by comparing people who differ in terms of their genetic similarity and the non-genetic influences they are exposed to. For example, we know that ...

Anxiety and stress are very available states, and since you want to know how people currently feel (rather than some more implicit construct), you probably can't do much better than just asking them. A single-item anxiety measure as suggested by mlt should work.

Just found out that the upcoming Apple Research Kit for iPhone allows for some kinds of motor and touch activity monitoring. Maybe some of these can be re-purposed to collect data relevant to the original question.

Short answer: We don't really know yet, but we should know soon. Long answer: There has been much research about the ego-depletion effect. The effect has been found in many published studies. As cited in APS Observer (2014): A recent meta-analysis revealed a medium effect size (d = 0.62) across 198 tests of the ego-depletion effect (Hagger, Wood, ...

I don't know of a single term for it, but what you're describing is, in essence, causal inference driven by "statistics", "co-variation", "co-occurrence", or "contiguity" (the terms are largely interchangeable). If you're interested, there's a quite in-depth discussion review of theories of different theories of causal inference, including statistical ...

Often I listen that this phenomenon has to do with the reticular activating system of the brain. For more details: http://www.innovateus.net/health/what-function-reticular-activating-system Also these type of event are labeled as synchronicity, a concept tagged by Carl Jung (psychic phenomenon).

In general humans are excellent at seeing patterns in randomness. It seems like you have attached special meaning to certain patterns. It seems similar to the way people form superstitions. Checking the time may also be something that we do so regularly and automatically that we do not know how often we do it. And it may be that the pattern confirming ...
