Abstract

This study examined the effects of program context on the memory of congruent or incongruent television (TV) advertisements on a youth sample (N = 123) aged 16 to 19 years. An experimental design was developed to test memory for a set of 6 car advertisements and 6 food advertisements within 2 program contexts: a car program and a food program. Memory for car advertisements was significantly better than memory for food advertisements in the free-recall condition, but the opposite was true in the cued-recall condition. Free recall of car advertisements in the food program was significantly better than of food advertisements in the food program. Levels of involvement were found to be unrelated to recall and recognition of advertisements.

Abstract

25 páginas.- 8 figuras.- 2 tablas.- 66 referencias.- Additional supporting information can be found online in the Supporting Information section at the end of this article., eaf water potential (psi(leaf)), typically measured using the pressure chamber, is the most important metric of plant water status, providing high theoretical value and information content for multiple applications in quantifying critical physiological processes including drought responses. Pressure chamber measurements of psi(leaf) (psi(leafPC)) are most typical, yet, the practical complexity of the technique and of the underlying theory has led to ambiguous understanding of the conditions to optimize measurements. Consequently, specific techniques and precautions diversified across the global research community, raising questions of reliability and repeatability. Here, we surveyed specific methods of psi(leafPC) from multiple laboratories, and synthesized experiments testing common assumptions and practices in psi(leafPC) for diverse species: (i) the need for equilibration of previously transpiring leaves; (ii) leaf storage before measurement; (iii) the equilibration of psi(leaf) for leaves on bagged branches of a range of dehydration; (iv) the equilibration of psi(leaf) across the lamina for bagged leaves, and the accuracy of measuring leaves with artificially 'elongated petioles'; (v) the need in psi(leaf) measurements for bagging leaves and high humidity within the chamber; (vi) the need to avoid liquid water on leaf surfaces; (vii) the use of 'pulse' pressurization versus gradual pressurization; and (viii) variation among experimenters in psi(leafPC) determination. Based on our findings we provide a best practice protocol to maximise accuracy, and provide recommendations for ongoing species-specific tests of important assumptions in future studies., European Union's Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie grant agreement No. 751918-AgroPHYS; Marie Curie Fellowship (FP7-PEOPLE-2013-IOF-624473); Austrian research agency (FWF) project P32203; National Science Foundation (Grant IOS-#1457279)
