AbstractThis experiment examined single‐process and dual‐process accounts of the development of visual recognition memory. The participants, 6–7‐year‐olds, 9–10‐year‐olds and adults, were presented with a list of pictures which they encoded under shallow or deep conditions. They then made recognition and confidence judgments about a list containing old and new items. We replicated the main trends reported by Ghetti and Angelini () in that recognition hit rates increased from 6 to 9 years of age, with larger age changes following deep than shallow encoding. Formal versions of the dual‐process high threshold signal detection model and several single‐process models (equal variance signal detection, unequal variance signal detection, mixture signal detection) were fit to the developmental data. The unequal variance and mixture signal detection models gave a better account of the data than either of the other models. A state‐trace analysis found evidence for only one underlying memory process across the age range tested. These results suggest that single‐process memory models based on memory strength are a viable alternative to dual‐process models for explaining memory development.

Introduction:Military personnel need to eat healthfully to enable peak performance and sustain health. Poor dietary habits and a rising rate of obesity among military personnel indicate a need for programs to improve food choices. This study evaluated two programs conceived under a dual-process model (consumer-focused communications only and a broader social marketing program including communications and environmental changes).Methods:Programs were implemented and evaluated over a 6-week period in two military dining halls in Australia. Food selections were measured before and after program implementation using plate photography ( N = 673 meals). Outcome variables included a healthy plate index (HPI), number of selections for food types, number of selections from three healthfulness categories (most healthful, moderately healthful, and least healthful), and a measure of how diner selections differed from the proportions of each healthfulness category available on the menu. Independent t tests were used to assess the difference between diner selections before and after program implementation.Results:Significant differences ( p < .05) in diner selections were observed after implementation of both programs, all in a healthful direction. When communications were used in isolation, the HPI was higher, with more selections made, and more moderately healthful selections chosen. When communications and environmental changes were combined, the number of choices remained stable but the HPI increased, and more of the most healthful foods were chosen.Conclusions:The eating behavior of military personnel can be improved using consumer-focused communications. However, by altering the environment as well, a greater change in behavior can be realized.

The impacts of help-seeking (HS) on purchase decisions associated with social media websites (SMWs) are deemed powerful given the enormous popularity of social media and growth of social commerce. This research explores HS on SMWs and empirically investigates how it influences users' decision performance. Utilizing the heuristic-systematic model (HSM), media system dependency (MSD) theory, and tangibility theory, in addition to HS logics, the research proposes a theoretical model incorporating both a MSD path and tangibility path for gauging purchase decision on SMWs. Two HS logics—dependent and autonomous—moderate the relationships between gratification, perceived diagnosticity, and decision performance. Data collected from 629 users of SMWs supported all of our hypotheses. Practitioners can benefit from the findings by more fully understanding the prospective value of diverse supports afforded by SMWs and constructing new guidelines to design more effective mechanisms that help consumers.

How does culture affect action? This question has long been framed in terms of a means vs ends debate-in other words, do cultural ends or cultural means play a primary causal role in human behavior? However, the role of socialization has been largely overlooked in this debate. In this book, Vila-Henninger develops a model of how culture affects action called "The Sociological Dual-Process Model of Outcomes" that incorporates socialization.This book contributes to the debate by first providing a critical overview of the literature that explains the limitations of the sociological dual-process model and subsequent scholarship-and especially work in sociology on "schemas". It then develops a sociological dual-process model of moral judgment that formally explains Type I processes, Type II processes, and the interaction between Type I and Type II processes. The book also expands sociological dual-process models to include a temporal dimension-the "Sociological Dual-Process Model of Outcomes". Finally, the book integrates a theory of socialization into the sociological dual-process model and creates empirical indicators that confirm Vila-Henninger's theorization and contribute to the literature on measures of dual-process models

Issue frames in policy discourse and news reporting regularly influence citizens' political opinions. Yet, we only have a limited understanding of how and among whom these framing effects occur. I propose a dual‐process model of issue framing effects arguing that we must understand mediators of framing (the how question) in connection with individual‐level moderators of framing (the whom question). Experimental results show that issue framing affects opinion through different psychological processes depending on who the receiver of the frame is. Among the moderately politically aware or those having weak political values, framing effects were mediated through processes of changing importance of considerations as well as changing content of considerations. Among the highly aware, only the importance change process mediated framing effects, while there were no framing effects among those least aware or those having strong values.
