This study examines adolescent hope as a mediator between connectedness to mother and father, and positive and negative child outcomes. Participants included 489 adolescents aged 9 to 14 years (M = 11.29; SD = 1.01) and their parents from the "Flourishing Families Project", and data were analyzed using structural equation modeling. Results…

The author integrates work from cognitive and developmental psychology with studies in writing in order to explain why the quality of student writing sometimes appears to regress to earlier or less proficient levels. Insights from this combined analysis are applied to explain how and why to use specific Writing Across the Curriculum strategies to…

A paradigmatic test of executive control, the n-back task, is known to recruit a widely distributed parietal, frontal, and striatal "executive network," and is thought to require an equally wide array of executive functions. The mapping of functions onto substrates in such a complex task presents a significant challenge to any theoretical…

A contrast category effect on categorization occurs when the decision to apply a category term to an entity not only involves a comparison between the entity and the target category but is also influenced by a comparison of the entity with 1 or more alternative categories from the same domain as the target. Establishing a contrast category effect…

This study developed and tested a new model of the cognitive processes associated with occupational/career indecision for gifted adolescents. A survey instrument with rigorous psychometric properties, developed from a number of existing instruments, was administered to a sample of 687 adolescents attending three academically selective high schools…

Understanding how geologists conduct fieldwork through analysis of problem solving has significant potential impact on field instruction methods. Recent progress has been made in this area but the problem solving behaviors displayed by geologists during fieldwork and the associated underlying cognition remains poorly understood. We present…

Previous research on dual-tasks has shown that, under some circumstances, actions impair the perception of action-consistent stimuli, whereas, under other conditions, actions facilitate the perception of action-consistent stimuli. We propose a new model to reconcile these contrasting findings. The planning and control model (PCM) of motorvisual…

Theory suggests that the vision-for-perception and vision-for-action processing streams operate under very different temporal constraints (Glover, 2004; Goodale, Jackobson, & Keillor, 1994; Graham, Bradshaw, & Davis, 1998; Hu, Eagleson, & Goodale, 1999). With the present study, children and young adults were asked to estimate how far a cued target…

Models and modeling are considered integral parts of scientific literacy, reflecting educators' efforts to introduce and engage students in authentic scientific inquiry through Modeling-based Learning (MbL) approaches in science. Over the years research has developed a considerable amount of knowledge concerning MbL. Our purpose in this paper was…

Four experiments were conducted to investigate how the cognitive control of memory retrieval selects particular qualitative characteristics as a consequence of instantiating a retrieval mode for recognition memory. Adapting the memory for foils paradigm from Jacoby, Shimizu, Daniels, and Rhodes (Jacoby, L. L., Shimizu, Y., Daniels, K. A., &…

This paper uses log-linear models with latent variables (Hagenaars, in "Loglinear Models with Latent Variables," 1993) to define a family of cognitive diagnosis models. In doing so, the relationship between many common models is explicitly defined and discussed. In addition, because the log-linear model with latent variables is a general model for…

This research explores communicative influences on cognitive learning and educational affect in online and offline courses limited to only enrolled students. A survey was conducted of students (N = 147) enrolled in online and offline courses within a single department during Summer, 2013. Respondents were asked about their classroom communication…

Although the characteristics of PBL (problem focused, student centered, self-directed, etc.) are well known, the components of a problem-based learning environment (PBLE) and the cognitive scaffolds necessary to support learning to solve different kinds of problems with different learners is less clear. This paper identifies the different…

This study involved the inclusion of special needs students in the general education classroom as required by law. The problem centered on general educators' perceptions of their abilities to meet the education needs of included students and their lack of training in special education issues. Research questions studied perceptions general…

This article used two studies to investigate sign and symbol mediation in children aged 8-11 years. In role play, children exist at one at the same time in objective reality and their representation of reality. We cannot observe their mental representation directly, but the issue of whether signs or symbols mediate early role play is an important…
