Age and memory essays

Age and memory essays It is a common stereotype that memory significantly gets worse as a person becomes older. There is now evidence that shows that these negative stereotypes may actually be negatively affecting the memory of older people who believe this to be true. Older adults who have more positive views on aging and memory have done better on memory performance tests than those who live in cultures where negative views on aging and memory surround them. A possible reason for this difference, is that when people convince themselves that aging effects memory, their effort and strategy use may be changed, which may ultimately effect their memory performance. In this journal, experimenters look at the effects of implicit priming and explicit priming of aging stereotypes. Implicit priming is activating certain associations in memory without conscious recollection, whereas explicit priming is activating associations in memory of facts and experiences. Both implicit and explicit priming were found to have an effect on older adults memory. This research article examines the relationship between age, culture, and memory performance. Researchers have found, overall, smaller age differences in groups of people who have more positive beliefs about aging. Ultimately, this finding illustrates the importance of aging stereotypes because of the influence they may have on memory. In the first experiment, young and old adults were either implicitly or explicitly primed with either positive or negative aging stereotypes, and then given a memory test after. This was done to test several things. First, they wanted to see if the effects of implicit stereotyping on memory performance are reliable with older adults. The researchers believed that this would be proved to be true, and that aging stereotypes would have a large impact on the memory of older adults, but very little on younger adults. Also, they wanted to test the extent to which awareness influenced t...

Element List - Atomic Number, Element Name and Symbol

Element List - Atomic Number, Element Name and Symbol Heres a list of chemical elements ordered by increasing atomic number. The names and element symbols are provided. Each element has a one or two letter symbol, which is an abbreviated form of its present or old name. The element number is its atomic number, which is the number of protons in each of its atoms. 1 - H - Hydrogen2 - He - Helium3 - Li - Lithium4 - Be - Beryllium5 - B - Boron6 - C - Carbon7 - N - Nitrogen8 - O - Oxygen9 - F - Fluorine10 - Ne - Neon11 - Na - Sodium12 - Mg - Magnesium13 - Al - Aluminum, Aluminium14 - Si - Silicon15 - P - Phosphorus16 - S - Sulfur17 - Cl - Chlorine18 - Ar - Argon19 - K - Potassium20 - Ca - Calcium21 - Sc - Scandium22 - Ti - Titanium23 - V - Vanadium24 - Cr - Chromium25 - Mn - Manganese26 - Fe - Iron27 - Co - Cobalt28 - Ni - Nickel29 - Cu - Copper30 - Zn - Zinc31 - Ga - Gallium32 - Ge - Germanium33 - As - Arsenic34 - Se - Selenium35 - Br - Bromine36 - Kr - Krypton37 - Rb - Rubidium38 - Sr - Strontium39 - Y - Yttrium40 - Zr - Zirconium41 - Nb - Niobium42 - Mo - Molybdenum43 - Tc - Technetium44 - Ru - Ruthenium45 - Rh - Rhodium46 - Pd - Palladium47 - Ag - Silver48 - Cd - Cadmium49 - In - Indium50 - Sn - Tin51 - Sb - Antimony52 - Te - Tellurium53 - I - Iodine54 - Xe - Xenon55 - Cs - Cesium56 - Ba - Barium57 - La - Lanthanum58 - Ce - Cerium59 - Pr - Pr aseodymium60 - Nd - Neodymium61 - Pm - Promethium62 - Sm - Samarium63 - Eu - Europium64 - Gd - Gadolinium65 - Tb - Terbium66 - Dy - Dysprosium67 - Ho - Holmium68 - Er - Erbium69 - Tm - Thulium70 - Yb - Ytterbium71 - Lu - Lutetium72 - Hf - Hafnium73 - Ta - Tantalum74 - W - Tungsten75 - Re - Rhenium76 - Os - Osmium77 - Ir - Iridium78 - Pt - Platinum79 - Au - Gold80 - Hg - Mercury81 - Tl - Thallium82 - Pb - Lead83 - Bi - Bismuth84 - Po - Polonium85 - At - Astatine86 - Rn - Radon87 - Fr - Francium88 - Ra - Radium89 - Ac - Actinium90 - Th - Thorium91 - Pa - Protactinium92 - U - Uranium93 - Np - Neptunium94 - Pu - Plutonium95 - Am - Americium96 - Cm - Curium97 - Bk - Berkelium98 - Cf - Californium99 - Es - Einsteinium100 - Fm - Fermium101 - Md - Mendelevium102 - No - Nobelium103 - Lr - Lawrencium104 - Rf - Rutherfordium105 - Db - Dubnium106 - Sg - Seaborgium107 - Bh - Bohrium108 - Hs - Hassium109 - Mt - Meitnerium110 - Ds - Darmstadtium111 - Rg - Roentgenium112 - Cn - Copernicium113 - Nh - Nihonium114 - Fl - Flerovium115 - Mc - Moscovium116 - Lv - Livermorium117 - Ts - Tennessine118 - Og - Oganesson Notes About Naming Most elements on the periodic table are metals and have the -ium suffix. Halogen names usually end with -ine. Noble gas names usually have the -on ending. Elements having names not following this naming convention tend to be ones known and discovered long ago. Future Element Names Right now, the periodic table is complete in that there are no remaining spots in the 7 periods. However, new elements may be synthesized or discovered. As with other elements, the atomic number will be determined by the number of protons within each atom. The element name and element symbol will need to be reviewed and approved by the IUPAC before inclusion on the periodic table. The element names and symbols may be proposed by the element discoverer, but often undergo revision before final approval. Before a name and symbol is approved, an element may be referred to by its atomic number (e.g., element 120) or by its systematic element name. The systematic element name is a temporary name that is based on the atomic number as a root and the -ium ending as a suffix. For example, element 120 has the temporary name unbinilium.
