  2. Hilbert–Huang transform - Wikipedia

    en.wikipedia.org/wiki/Hilbert–Huang_transform

    Identify all the local extrema in the test data. Connect all the local maxima by a cubic spline line as the upper envelope. Repeat the procedure for the local minima to produce the lower envelope. The upper and lower envelopes should cover all the data between them. Their mean is m 1. The difference between the data and m 1 is the first ...

  3. Absolute threshold - Wikipedia

    en.wikipedia.org/wiki/Absolute_threshold

    The absolute threshold of hearing is the minimum sound level of a pure tone that an average ear with normal hearing can hear with no other sound present. The absolute threshold relates to the sound that can just be heard by the organism.

  4. Stanford prison experiment - Wikipedia

    en.wikipedia.org/wiki/Stanford_prison_experiment

    The Stanford prison experiment (SPE) was a psychological experiment performed during August 1971. It was a two-week simulation of a prison environment that examined the effects of situational variables on participants' reactions and behaviors. Stanford University psychology professor Philip Zimbardo managed the research team who administered ...

  5. Maximum entropy probability distribution - Wikipedia

    en.wikipedia.org/wiki/Maximum_entropy...

    By the above equation it is thus clear, that the latter must be the case. Hence ′ = = , so the parameters characterising the local extrema , ′ are identical, which means that the distributions themselves are identical. Thus, the local extreme is unique and by the above discussion, the maximum is unique – provided a local extreme actually ...

  6. Experimental psychology - Wikipedia

    en.wikipedia.org/wiki/Experimental_psychology

    Experimental psychology refers to work done by those who apply experimental methods to psychological study and the underlying processes. Experimental psychologists employ human participants and animal subjects to study a great many topics, including (among others) sensation, perception, memory, cognition, learning, motivation, emotion; developmental processes, social psychology, and the neural ...

  7. List of psychological research methods - Wikipedia

    en.wikipedia.org/wiki/List_of_psychological...

    Qualitative psychological research findings are not arrived at by statistical or other quantitative procedures. Quantitative psychological research findings result from mathematical modeling and statistical estimation or statistical inference. The two types of research differ in the methods employed, rather than the topics they focus on.

  8. Identification (psychology) - Wikipedia

    en.wikipedia.org/wiki/Identification_(psychology)

    This quality or ideal is often represented in a "leader figure" who is identified with. For example: the young boy identifies with the strong muscles of an older neighbour boy. Next to identification with the leader, people identify with others because they feel they have something in common. For example: a group of people who like the same music.

  9. Parks–McClellan filter design algorithm - Wikipedia

    en.wikipedia.org/wiki/Parks–McClellan_filter...

    The extrema must occur at the pass and stop band edges and at either ω=0 or ω=π or both. The derivative of a polynomial of degree L is a polynomial of degree L−1, which can be zero at most at L−1 places. [3] So the maximum number of local extrema is the L−1 local extrema plus the 4 band edges, giving a total of L+3 extrema.
