Multi-domain Models of Risk Factors for Depression and Anxiety Symptoms in Preschoolers: Evidence for Common and Specific Factors

Relatively few studies have examined multiple pathways by which risk factors from different domains are related to symptoms of anxiety and depression in young children; even fewer have assessed risks for these symptoms specifically, rather than for internalizing symptoms in general. We examined a theoretically- and empirically-based model of variables associated with these symptom types in a diverse community sample of 796 4-year-olds (391 boys, 405 girls) that included factors from the following domains: contextual (SES, stress and family conflict); parent characteristics (parental depression); parenting (support/engagement, hostility and scaffolding); and child characteristics including negative affect (NA) effortful control (EC) sensory regulation (SR), inhibitory control (IC) and attachment. We also compared the models to determine which variables contribute to a common correlates of symptoms of anxiety or depression, and which correlates differentiate between those symptom types. In the best-fitting model for these symptom types (a) SES, stress and conflict had indirect effects on both symptom types via long-chain paths; (b) caregiver depression had direct effects and indirect ones (mediated through parenting and child effortful control) on both symptom types; (c) parenting had direct and indirect effects (via temperament and SR); and temperament had direct effects on both symptom types. These data provide evidence of common risk factors, as well as indicate some specific pathways/mediators for the different symptom types. EC was related to anxiety, but not depression symptoms, suggesting that strategies to improve child EC may be particularly effective for treatment of anxiety symptoms in young children.     

Adapting Motivation,Control, and Compensation Research to A New Environment

The authors discuss the need to adapt research in three substantively related but paradigmatically diverse research domains (salesperson motivation, control systems, and compensation) in light of the evolving selling environment. A key objective is to suggest the desirability of integrating these literatures, which, ultimately, all seek to inform management regarding how salespeople and sales organizations can be encouraged to become more productive. The authors maintain that specification of the right goals and metrics constitutes a fundamental common denominator across the three literatures.     

Two-Year-Olds' Object Retrieval Based on Television: Testing a Perceptual Account

Two-year-olds frequently fail to use information provided by video to find objects hidden in an adjacent room. Schmitt and Anderson (2002) hypothesized that they fail to map the 2-dimensional (2D) video image onto the 3D layout of the search space. Two experiments tested whether 2-year-olds can successfully use information from video when the search space is 2D or when the information is provided verbally (by telling the child where the toy is hidden). In both experiments, children performed poorly in the video conditions but performed well in direct live experience comparison conditions, contradicting Schmitt and Anderson's hypothesis. Performance was above chance on the first trial in the video conditions, suggesting that 2-year-olds do have a memory of the hiding location, albeit one that is easily disrupted by perseverative errors on subsequent trials. Overall, the results are most consistent with the hypothesis that very young children give priority to direct experience over mediated information.     

Learning Impacts of a Digital Augmentation in a Science Museum

ABSTRACT

This study investigated the effects of using digital augmentation to enhance an exhibit device to influence conceptual understanding about a science topic in a science museum setting. In particular, the study considered how students in Grades 6–8 engaged with the device that was available in both augmented and nonaugmented (control) conditions. Results show increased cognitive (critical thinking) skills when the digital augmentation was present that we hypothesize led to increased conceptual gains. We illustrate how this research contributes to three important areas of need identified in informal science literature: the need for evidence of conceptual and cognitive gains; the need for understanding how digital platforms improve the learning experience; and the need to demonstrate how designed interactive devices may impact higher order skills such as critical thinking and theorizing.     

Problem-solving Strategies and Expertise in Engineering Design

A study is reported which focused on the problem-solving strategies employed by expert electronics engineers pursuing a real-world task: integrated-circuit design. Verbal protocol data were analysed so as to reveal aspects of the organisation and sequencing of ongoing design activity. These analyses indicated that the designers were implementing a highly systematic solution-development strategy which deviated only a small degree from a normatively optimal top-down and breadth-first method. Although some of the observed deviation could be described as opportunistic in nature, much of it reflected the rapid depth-first exploration of tentative solution ideas. We argue that switches from a predominantly breadth-first mode of problem solving to depth-first or opportunistic modes may be an important aspect of the expert's strategic knowledge about how to conduct the design process effectively when faced with difficulties, uncertainties, and design impasses.     

Predicting the difficulty of complex logical reasoning problems

The aim of the present research was to develop a difficulty model for logical reasoning problems involving complex ordered arrays used in the Graduate Record Examination. The approach used involved breaking down the problems into their basic cognitive elements such as the complexity of the rules used, the number of mental models required to represent the problem, and question type. Weightings for these different elements were derived from two experimental studies and from the reasoning literature. Based on these weights, difficulty models were developed which were then tested against new data. The models had excellent predictive validity and showed the relative influence of rule based factors and factors relating to the number of underlying models. Different difficulty models were needed for different question types, suggesting that people used a variety of approaches and, at a wider level, that both mental models and mental rules may be used in reasoning.

Extending Autonomy for Health Care Preferences in Late Life

Mechanisms for extending autonomy in financial and health care decisions (e.g., advanced directives) are being utilized more frequently. This study examined the hierarchy of documents completed, the characteristics of people completing these documents, the choice of surrogate decision-maker for health care decisions, and with whom health care decisions were being discussed in a sample of 661 persons 65 years of age and older. Comparison between people with and without documents in place suggested that cognitive impairment, level of education, and age were related to preparation of documents. Women were typically chosen as surrogate decision-makers, except in a sample of unmarried men. Surprisingly, participants reported discussing preferences for health care decisions with someone other than their preferred surrogate. There appears to be a need to promote discussion of health care preferences between care-receivers and preferred surrogates.     

Appearance feedback in intimate relationships: The role of self-verification and self-enhancement

To better understand how body image operates within the context of intimate relationships, we investigated women's responses to appearance feedback from an intimate partner. Participants (N = 192) imagined receiving feedback from their partner that was either consistent with their own appearance self-view (i.e., self-verifying), more positive (i.e., self-enhancing), or less positive (i.e., devaluing), and then provided their affective and cognitive reactions. As expected, women's perceptions of their own appearance moderated their reactions. Women with more negative self-views felt happier with enhancing feedback, but thought that it meant their partner understood them less well. They also felt less happy when they received verifying feedback, but felt more understood by their partners. Thus, women with body image dissatisfaction may find themselves stuck in the “cognitive-affective crossfire” reacting ambivalently whether their partner enhances their appearance or confirms their negative self-views. Further examination of partners’ actual feedback is needed.
