Four studies comparedmemoryfor material that varied in humor, aggressive sexuality (tendency), and style. The findings were that humor improved memoryfor the material but arousing material increased recall further and interacted additively with humor. Humor seemed to have an effect on attention and selection of material while tendency influenced motivation and strength of recall Humor's role in education is assured. No matter how uncertain the effect of humor on appropriate attention and relevant memory, it is irresistible in the classroom. Indeed, when amusement is relevant to the task, äs in the memory for jokes to be transmitted in a social setting, there is a positive, if slight, effect on recall.In the earliest published study, Heim (1936) found that after a delay of between two and twenty-four weeks, 62 percent of the material initially laughed at was remembered, while only 8 percent of the material that did not elicit laughter was recalled. This figure was inflated slightly by the inclusion of three not-funny Stimuli that were remembered better than "slightly funny" Stimuli. In fact, with some computational gymnastics, it can be ascertained that on a 5 point scale (assuming "very funny" = 4 to "not funny" = 0) the remembered items were rated an average of 2.1 (just more than "funny") while the not remembered items averaged 1.3 (somewhat more than "slightly funny"). In spite of these reasonably clear results, Heim concludes that, "The main result of this experiment is to make one exceedingly chary of setting up any rules on the subject of humor" (p. 161).
SynopsisIt is known that aromatic hydrocarbons are more stable to ionizing radiation than are saturated hydrocarbons. It is shown here that polyethylene can be more stable to radiation either by mixing aromatic compounds with the polyethylene or by grafting styrene onto the polyethylene. In either case, the polymer has greater radiation re'-sistance than predicted from the law of averages. Aromatic compounds which have the greatest resonance energy protect the polymer to the greatest extent. In mixtures, polystyrene gives the least protection, and naphthalene, anthracene, and phenanthrene give the greatest protection. Polyethylene grafted with styrene has better radiation resistance than does a polyethylene-polystyene mixture. The G( H2) was calculated for each sample, and curves are presented illustrating the effect.

SynopsisIt haa been previously reported that vinyl esters have been grafted to natural rubber latex. We have grafted two other types of vinyl monomers to styrene-butadiene latex. These monomers are the ammonium salts of acrylic acid and methacrylic acid, and the ammonium salts of vinyl chelating agents, such aa N-( ar-vinylbenay1)iminodiacetic acid. (Ioniziig radiation doses of 0.5-2 Mrad are sufficient to accomplish the grafting.) These monomers, in the range of 2-6%, give very definite improvement in adhesion to metals. They also improve the rust resistance, and when pigmented with an iron oxide dispersion, improve the whitening resistance of the coating. The vinyl chelating monomers give the best improvement over the untreated latex, particularly in the resistance to whitening. The optimum amount of monomer is 44%. This compares very well with the theoretical amount for a monomolecular layer of monomer surrounding each latex particle.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
