Insulin has been shown to impact on learning and memory in both humans and animals, but the downstream signaling mechanisms involved are poorly characterized. Insulin receptor substrate-2 (Irs2) is an adaptor protein that couples activation of insulin- and insulin-like growth factor-1 receptors to downstream signaling pathways. Here, we have…

By setting foot back in the space of school, teachers stage a return that is necessarily uncanny, encountering a strangeness that is nonetheless known, intimate, and familiar. Through positing the notion of a "burden of feeling," this article theorizes the psychoanalytic concept of the uncanny as a way to think through the narrative…

When referring to named objects, speakers can choose either a name ("mbira") or a description ("that gourd-like instrument with metal strips"); whether the name provides useful information depends on whether the speaker's knowledge of the name is shared with the addressee. But, how do speakers determine what is shared? In 2…

Infants are able to map linguistic labels to referents in the world by tracking co-occurrence probabilities across learning events, a behavior often termed "cross-situational statistical learning." This study builds upon existing research by examining infants' developing ability to aggregate and retrieve word-referent pairings over time. 16- and…

Many important problems require consideration of multiple constraints, such as choosing a job based on salary, location, and responsibilities. We used the Remote Associates Test to study how people solve such multiply-constrained problems by asking participants to make guesses as they came to mind. We evaluated how people generated these guesses…

As a teacher, the author is always seeking the meaning behind her educational practice with children, colleagues, and the institution in which she works on a daily basis. Dr. Jonathon Silin's thinking around loss, collective memory and social amnesia resonate strongly with her (Silin, 2011). In this article, the possibilities of intentionally…

In responding to Jonathan Silin's article "At a Loss: Scared and Excited", the author takes up his invitation to articulate a relationship between the personal and the professional, and contemplates the autobiographical as more than a mode of recounting one's own experience. In so doing he foregrounds possibilities for working with an…

Recent neuroimaging studies suggest that the human brain activates dissociable cognitive control networks in response to conflicts arising within the cognitive and the affective domain. The present study tested the hypothesis that nonemotional and emotional conflict regulation can also be dissociated on a functional level. For that purpose, we…

Atkinson and Shiffrin's (1968) dual-store model of memory includes structural aspects of memory along with control processes. The rehearsal buffer is a process by which items are kept in mind and long-term episodic traces are formed. The model has been both influential and controversial. Here, we describe a novel variant of Atkinson and Shiffrin's…

Spatial memories are often organized around reference frames, and environmental shape provides a salient cue to reference frame selection. To date, however, the environmental cues responsible for influencing reference frame selection remain relatively unknown. To connect research on reference frame selection with that on orientation via…

In a study on learning in serious games, 45 players were tested for topic-comprehension by a questionnaire administered before and after solo-playing of the serious game "Peacemaker" (Impact Games 2007), during which their psychophysiological signals were measured. Play lasted for 1 h, with a break at half time. The questionnaire was divided into…

For stable perception, we maintain mental representations of objects across space and time. What information is linked to such a representation? In this study, we extended our work showing that the spatiotemporal history of an object affects the way the object is attended the next time it is encountered. Observers conducted a visual search for a…

Proactive interference (PI) refers to the finding that memory for recently studied (target) information can be vastly impaired by the previous study of other (nontarget) information. PI can be reduced in a number of ways, for instance, by directed forgetting of the prior nontarget information, the testing of the prior nontarget information, or an…

This study investigated the effects of two different true-false questions on memory awareness and long-term retention of knowledge. Participants took four subsequent knowledge tests on curriculum learning material that they studied at different retention intervals prior to the start of this study (i.e. prior to the first test). At the first and…

Executive functions (EFs) may help children to regulate their food-intake in an "obesogenic" environment, where energy-dense food is easily available. There is mounting evidence that overweight is associated with diminished hot and cool EFs, and several longitudinal studies found evidence for a predictive effect of hot EFs on children's…
