It has been argued that title confusion may profoundly impact the audience estimates of competitive magazines and their respective demographic profiles. Title confusion is a phenomenon that potentially occurs when respondents are uncertain about their readership of magazines, specifically when confronted by similarly titled magazines and/or magazin...

As a social species in a constantly changing environment, humans rely heavily on the informational richness and communicative
capacity of the face. Thus, understanding how the brain processes information about faces in real-time is of paramount importance.
The N170 is a high-temporal resolution electrophysiological index of the brain’s early respon...
External circumstances and internal bodily states often change and require organisms to flexibly adapt valuation processes to select the optimal action in a given context. Here, we investigate the neurobiology of context-dependent valuation in 22 human subjects using functional magnetic resonance imaging. Subjects made binary choices between visual...
The current study investigated the effects of stimulus symmetry on the processing of global and local stimulus properties by 6-month-old short-and long-looking infants through the use of event-related potentials (ERPs). Previous research has shown that individual differences in infant visual attention are related to hierarchical stimulus processing...
Visual object recognition is classically believed to involve two stages: a perception stage in which perceptual information is integrated, and a memory stage in which perceptual information is matched with an object's representation. The transition from the perception to the memory stage can be slowed to allow for neuroanatomical segregation using...
In the interest of determining if several visual instruction stimuli used in commercial exercise games/software are viable for use with rehabilitative exercise games/software, this study quantitatively compares a selection of instructional stimuli. We hypothesize that if a difference in the accuracy of the results produced by each stimuli type exis...

... While the findings (mentioned briefly below) strongly concluded convenience Internet panel biases precluded using these sample frames as the basis of a print ratings system, MRI continued its investigation into other uses of Internet panels for magazine research. We reported our findings on studying possible title confusion at the 2005 Worldwide Readership Symposium (Baim et al, 2005) and shared our initiative on measuring issue-specific readership at the 2007 Worldwide Readership Symposium (Frankel et al, , 2007; Baim et al., 2007). Since then, we have continued the Issue-Specific Measurement service and have used convenience, opt-in Internet panels for our AdMeasures service. ...
Using convenience, opt-in Internet panels as sampling frames has become virtually commonplace in today's survey research world. The movement towards Web-based convenience panels is inevitable, given the relatively low cost of these samples, the shorter time frames for completing surveys and the flexibility provided by the Internet for conducting complex surveys. As with every dramatic change in sample selection and/or interviewing mode, concern arises among survey practitioners about the impact potentially radical changes have on survey results from previously employed other sampling procedures. This unease is especially felt among magazine researchers because print audience ratings services are the cornerstone of the buying and planning processes. It is equally disconcerting because many of the country-specific print rating services still employ area probability, in-person surveys with an effort to ensure every eligible respondent has a known probability of being selected. Over the past 8 years, Mediamark Research & Intelligence (MRI) has explored the impact of using convenience Internet panels on audience ratings and has even utilized these studies in providing more granular information about magazine reading. We have approached Internet panels with a substantial degree of trepidation since we are very cognizant of the potential biases associated with these sampling frames. Beyond analyzing potential uses of Internet panels for magazine research, we have also examined the relative performances of different panels and developed some clear guidelines about the uses and misuses of these sampling frames. This paper discusses the insights gleaned from conducting almost 750,000 surveys on the Internet using convenience panels and tries to offer the proper context in which magazines can use convenience panels for very specific purposes. Although the findings reflect our experience with opt-in Internet panels in the United States, they address issues faced by researchers in many other countries. BACKGROUND
