Creativity is a multifaceted construct that recruits different cognitive processes. Here, we summarize studies that show that creativity develops considerably during adolescence with different developmental trajectories for insight, verbal divergent thinking, and visuospatial divergent thinking. Next, these developmental time courses are mapped to…

When subjects learn to associate two sample durations with two comparison keys, do they learn to associate the keys with the short and long samples (relational hypothesis), or with the specific sample durations (absolute hypothesis)? We exposed 16 pigeons to an ABA design in which phases A and B corresponded to tasks using samples of 1 s and 4 s,…

It is now well-established that intrinsic variations in human neural and behavioral activity tend to exhibit scaling laws in their fluctuations and distributions. The meaning of these scaling laws is an ongoing matter of debate between isolable causes versus pervasive causes. A spiking neural network model is presented that self-tunes to critical…

Developmental research is enhanced by use of multiple methodologies for examining psychological processes. The electroencephalogram (EEG) is an efficient and relatively inexpensive method for the study of developmental changes in brain-behavior relations. In this review, we highlight some of the challenges for using EEG in cognitive development…

In the Winter 2013 issue of "Independent School," Richard Barbieri considered some of the distressing news about humanity being discovered by various physical and social scientists. Barbieri asserts in this issue that there are countervailing views and discoveries about our minds and our mores, enough for us to hope for the frequent, if…

In our increasingly multicultural and multilingual world, an understanding of how we perceive language, dialects, and linguistic variation and the relationship these features have to language attitude, plays an increasingly important role in shaping social behavior and policy. This study, situated at the intersection of cognitive neuroscience,…

Episodic memories contain various forms of contextual detail (e.g., perceptual, emotional, cognitive details) that need to become integrated. Each of these contextual features can be used to attribute a memory episode to its source, or origin of information. Memory for source information is one critical component in the formation of episodic…

Previous repetitive Transcranial Magnetic Stimulation and neuroimaging studies showed that Broca's area is involved in the interaction between gestures and words. However, in these studies the nature of this interaction was not fully investigated; consequently, we addressed this issue in three behavioral experiments. When compared to the…

When the bottom halves of two faces differ, people's behavioral judgment of the identical top halves of those faces is impaired: they report that the top halves are different, and/or take more time than usual to provide a response. This behavioral measure is known as the composite face effect (CFE) and has traditionally been taken as evidence that…

In everyday life, one can link anticipated specific cues (e.g. visiting a restaurant) with desired actions (e.g., ordering a healthy meal). Alternatively, intentions such as "I intend to eat more healthily" present the option to act when one encounters the same cue. In the first case, a specific cue triggers a specific action; in the second, one…

The authors propose a simple behavioral economic model (BEM) describing how reinforcement and interval timing interact. The model assumes a Weber-law-compliant logarithmic representation of time. Associated with each represented time value are the payoffs that have been obtained for each possible response. At a given real time, the response with…

Ahmad R. Hariri, recipient of the Award for Distinguished Scientific Early Career Contributions to Psychology, is cited for pioneering contributions to understanding the neurobiological mechanisms driving individual differences in complex behavior traits. Hariri has integrated molecular genetics, neuropharmacology, neuroimaging, and psychology in…

A model of memory retrieval is described. The model embodies four main claims: (a) temporal memory--traces of items are represented in memory partly in terms of their temporal distance from the present; (b) scale-similarity--similar mechanisms govern retrieval from memory over many different timescales; (c) local distinctiveness--performance on a…

Individuals with autism demonstrate impairments on measures of executive function (EF) relative to typically developing comparison participants. EF is comprised of several processes including inhibition, working memory and set shifting that develop throughout the lifespan. Impairments in EF may appear early in development and persist, or may…

The past two decades have provided extraordinary progress in our understanding of the nature of learning. Never before have neuroscience and classroom instruction been so closely linked. Now, educators can find evidence-based neuroimaging and brain-mapping studies to determine the most effective ways to teach, as advances in technology enable…
