The transcription factor cAMP response-element binding protein (CREB) has a pivotal role in hippocampal synaptic plasticity and hippocampus-dependent long-term memory. We recently demonstrated that the dorsal hippocampal CA3 region is involved in memory consolidation of spatial information tested on a Morris water maze in mice. To test whether…

Lesions of the basolateral amygdala (BLA) have long been associated with abnormalities of taste-related behaviors and with failure in a variety of taste- and odor-related learning paradigms, including taste-potentiated odor aversion, conditioned taste preference, and conditioned taste aversion. Still, the general role of the amygdala in…

The first gene-targeting studies that examined learning and memory in mice were performed in 1992 (Grant et al. 1992; Silva et al. 1992). The ultimate goal of this new field was to understand the molecular and cellular process underlying normal cognition and how they may be altered in disease states. In the years since these pioneering studies,…

Although an important role for the mitogen-activated protein kinase (MAPK) has been established for memory consolidation in a variety of learning paradigms, it is not known if this pathway is also involved in appetitive classical conditioning. We address this question by using a single-trial food-reward conditioning paradigm in the freshwater…

In this article, the author describes an activity which was implemented in response to a question posed by her student. It was not a study implemented formally and so cannot offer contrasts and comparisons with previous student results. However, no student in this particular group handed in work that was below a pass. The exercise indicated that…

Two experiments investigated the factors that govern children's use of singular and plural forms of count nouns. Experiment 1 used an elicited production task to investigate whether children use referential and/or syntactic information to determine the form of the count nouns when the two sources of information conflict (e.g. "each x, one of the…

In this paper, we have attempted two ambitious tasks. We have undertaken a wide-ranging survey of the Network learning (NL) literature, and tried to identify the emerging themes of this work. We have selected three of these themes, and in each case tried to identify the main theoretical perspectives in use, the main directions of the studies, and…

Purpose: This paper aims to generate both a theoretical and an empirical basis for a research model that serves in further research as an analytical tool for understanding the complex phenomenon of learning at different levels in a work organisation. The key concept in this model is the routine concept of Nelson and Winter.…

Hebbian learning is a biologically plausible and ecologically valid learning mechanism. In Hebbian learning, "units that fire together, wire together". Such learning may occur at the neural level in terms of long-term potentiation (LTP) and long-term depression (LTD). Many features of Hebbian learning are relevant to developmental theorizing,…

Software complexity is the most important software quality attribute and a very useful instrument in the study of software quality. Is one of the factors that affect most of the software quality characteristics, including maintainability. It is very important to quantity this influence and identify the means to keep it under control; by using…

Art in Education is generally considered a sideline, a secondary specialty, or something to be integrated into the primary curriculum, i.e. literacy and arts integration. But art is not secondary; it is primary in learning and in human development. Art is, in fact, necessary and optimal for learning to write, read, and perform arithmetic. This…

The author describes his program of research over the past 25 years. This research falls into 6 areas that are interdependent and that inform each other. The overall program is guided by 3 bioecological principles that posit the need for proximal processes and motivation to actualize biological potential. The author presents examples of…

In this paper we examine discourse and interaction during Saturday morning religious instruction classes in a Gitano (Spanish Romani) evangelist church. The focus is on adults as literacy mediators for the children in the process of learning ways to use and interpret the Bible. The analysis centres on two aspects: (1) the forms of textuality that…

Bedtime resistance, a common pediatric problem, that was displayed by 4 unrelated 3-year-old children was treated with the bedtime pass (i.e., provision of a small notecard exchangeable for one trip out of the bedroom after bedtime) plus extinction. Bedtime resistance was eliminated for all participants. Further, treatment did not produce…

This article discusses an approach to teacher belief systems which casts an eye away from cognitive constructs toward sociological constructs to complement existing ideas about the nature and genesis of beliefs. I offer some theoretical ideas for extending the notion of beliefs and describe two contrasting senior mathematics teachers,…
