  2. Serial-position effect - Wikipedia

    en.wikipedia.org/wiki/Serial-position_effect

    Serial-position effect is the tendency of a person to recall the first and last items in a series best, and the middle items worst. [1] The term was coined by Hermann Ebbinghaus through studies he performed on himself, and refers to the finding that recall accuracy varies as a function of an item's position within a study list. [ 2 ]

  3. Recall test - Wikipedia

    en.wikipedia.org/wiki/Recall_test

    The primacy effect extended over the first four serial positions. [2] Serial recall paradigm is a form of free recall where the participants have to list the items presented to them in the correct order they are presented in. Research shows that the learning curve for serial recall increases linearly with every trial.

  4. Free recall - Wikipedia

    en.wikipedia.org/wiki/Free_recall

    The primacy effect extended over the first four serial positions. [2] Another evidence of the recency effect is found in the way that participants initiate recall of a list: they most often start with terminal (recent) list items (an early description of the recency effect in the probability of first recall can be found in Hogan, 1975 [3 ...

  5. Specific ion interaction theory - Wikipedia

    en.wikipedia.org/.../Specific_ion_interaction_theory

    In theoretical chemistry, Specific ion Interaction Theory (SIT theory) is a theory used to estimate single-ion activity coefficients in electrolyte solutions at relatively high concentrations. [ 1 ] [ 2 ] It does so by taking into consideration interaction coefficients between the various ions present in solution.

  6. Modality effect - Wikipedia

    en.wikipedia.org/wiki/Modality_effect

    In short-term sentence recall studies, emphasis is placed on words in a distractor-word list when requesting information from the remembered sentence. This demonstrates the modality effect can be more than auditory or visual. [2] For serial recall, the modality effect is seen in an increased memory span for auditorally presented lists. Memory ...

  7. Atkinson–Shiffrin memory model - Wikipedia

    en.wikipedia.org/wiki/Atkinson–Shiffrin_memory...

    When serial-position curves are applied to SAM, a strong recency effect is observed, but this effect is strongly diminished when a distractor, usually arithmetic, is placed in between study and test trials. The recency effect occurs because items at the end of the test list are likely to still be present in short-term store and therefore ...

  8. Stereoelectronic effect - Wikipedia

    en.wikipedia.org/wiki/Stereoelectronic_effect

    If there is an electropositive substituent (e.g. –SiR 3, –SnR 3, –HgR, etc.) at the β-position of carbocation, the positive charge could be stabilized which is also due largely to the stereoelectronic effect (illustrated below using –SiR3 as an example). The orientation of the two interacting orbitals can have a significant effect on ...

  9. VSEPR theory - Wikipedia

    en.wikipedia.org/wiki/VSEPR_theory

    VSEPR theory is used to predict the arrangement of electron pairs around central atoms in molecules, especially simple and symmetric molecules. A central atom is defined in this theory as an atom which is bonded to two or more other atoms, while a terminal atom is bonded to only one other atom.
