Vogels and Orban (1985) asked subjects to complete several thousand angle judgments at near-principal angles (horizontal or vertical). They found that the just-noticeable difference (JND), the threshold at which people could reliably detect deviation from a horizontal line, was 0.5 degrees after a 600ms exposure to the stimulus. The real purpose of their ...

Logical semantics is one of the three sections of logical semiotics (in addition to syntax and pragmatics) dealing with the relations between signs (in particular the expressions) and reality, to which they refer. In addition to basic semantic functions, we can include, e.g. semantic connotation, determination and denotation, where the basic terms of ...

The term is typically called déjà vu.. There's a section on wikipedia discussing scientific research. Brown (2003) looks like a good starting point for a more rigorous scientific analysis. Kusumi (2006, PDF) has another scientific review article on the topic. References Brown, A. S. (2003). A review of the déjà vu experience. Psychological bulletin, ...

Your information is basically sound. Serotonin and dopamine are both neurotransmittors that are connected, in different ways, with positive feelings or elevated mood.

Using Google's search by image feature, I found that the image is usually entitled Richard Gregory dalmatian. From there, I found this page, which cites the image as coming from Gregory's 1970 book The Intelligent Eye. There's also, incidentally, a good list of Gregory's publications on this personal web page, which is probably worth looking at. From a ...

Citing Muller et al’s, (1955) work on electronic displays, Eastman Kodak’s (1983) Ergonomics Design for People at Work states that people can discriminate 24 different absolute angles of inclination under optimum viewing conditions. This implies that an angle of 360/24 = 15 degrees can be readily classified as inclined rather than flat. However, I’d say 15 ...

This is more appropriate as a comment but I don't have sufficient reputation at the moment. Jeromy Anglim's answer is excellent but I thought I'd mention that the term was missing the diacritic marks, or pronunciation symbols above the e and a: déjà vu. This viral video by vsauce is excellent and entertaining, so I thought it was worth mentioning: ...

I hope you still see this. I don't know a specific term for the exact kind of problem you mentioned. However, I would think that it can be explained by linguistic as well as cognitive or memory processes. Hence, my proposed explanation comes in two parts. Linguistics One view would be that it has to do with how we interpret language, specifically that we ...

I might be wrong but it might have something associated with the numerical goals we acheive as children, young adults and grown up. For example, becoming 10 years of age is a sign of maturity, mainly due to the double digits it contains. This leads us (as children) to believe that we are that much closer to becoming adults. When people turn 40 or 50 they put ...

I'm by no means an expert or qualified, but here's my thoughts. I believe there are a few factors at play: Our Privacy The first is the perception that the information carries some threat to their lifestyle or reputation, e.g. an adult who views pornography or a cheating spouse, for both of whom this causes that initial concern of the threat of exposure ...

A common definition of "conflict" is readily retrievable and applicable in the context of clinical evaluation – i.e., conflict has no particularly unusual primary meaning in clinical psychology. "Interpersonal" also operates as an ordinary adjective with the usual meaning. Thus interpersonal conflict is conflict between persons, as might be distinguished ...
