Intense focus on student achievement results in mathematics and science has brought about claims that K-12 teachers should be better prepared to teach basic concepts in these disciplines. The focus on teachers' mathematics and science content knowledge has been met by efforts to increase teacher knowledge through funded national initiatives…

Processing speed plays an important role in numerous facets of life functioning. Language, academic achievement, and behavior are all associated with processing speed; however, researchers have yet to investigate the effect of interventions, particularly language-based interventions, on the processing speed and the behavioral functioning of…

Objective: This study investigates college students' behaviors in response to the calories ingested by drinking alcohol. Participants and Methods: A sample of 274 nonclinical undergraduate alcohol drinkers completed an online survey asking about behaviors that students employed to make up for calories in alcohol or to get drunk more effectively.…

Defining intelligence is a puzzle that has challenged educators and researchers for years. More recently, professionals are acknowledging that individuals possess many facets of intelligence and that learning is a complex combination of genetic factors, environmental influences, and life experiences that affect learning in unique ways (Salvia,…

Experts are frequently called upon to serve as instructors in their disciplines. However, studies indicate that their unaided explanations contain significant inaccuracies and omissions that negatively impact the effectiveness of instruction. Cognitive task analysis (CTA) is an effective tool for eliciting, analyzing, and representing expert…

Hierarchy is one of the most important concepts in the scientific study of language. This dissertation aims to understand why we observe hierarchical structures in speech by investigating the cognitive processes from which they emerge. To that end, the dissertation explores how articulatory, rhythmic, and prosodic patterns of speech interact.…

Determining whether patients with amnesia can succeed in remembering their distant past has pivotal implications for theories of memory storage. However, various factors influence recall. We speculated that some patients with anterograde amnesia adopt a gist-based retrieval orientation for memories from all time periods, thereby exaggerating…

In this response to Reis's and Zuss's responses to our meditation on the grotesque, we attempt to draw distinctions between positivist, empiricist, and realist (including grotesque realist) projects. We also, drawing on Bakhtin, consider the difference between dialogic and dialectic commentary.

Face processing changes when a face is learned with personally relevant information. In a five-day learning paradigm, faces were presented with rich semantic stories that conveyed personal information about the faces. Event-related potentials were recorded before and after learning during a passive viewing task. When faces were novel, we observed…

In synesthesia, stimulation of one sensory modality leads to a percept in another nonstimulated modality, for example, graphemes trigger an additional color percept in grapheme-color synesthesia, which encompasses the variants letter-color and digit-color synesthesia. Until recently, it was assumed that synesthesia occurs strictly unidirectional:…

Conflict-related cognitive processes are critical for adapting to sudden environmental changes that confront the individual with inconsistent or ambiguous information. Thus, these processes play a crucial role to cope with daily life. Generally, conflicts tend to accumulate especially in complex and threatening situations. Therefore, the question…

Incubation has long been proposed as a mechanism in creative problem solving (Wallas, 1926). A new trial-by-trial method for observing incubation effects was used to compare the forgetting fixation hypothesis with the conscious work hypothesis. Two experiments examined the effects of incubation on initially unsolved Remote Associates Test (RAT)…

This study investigated how 4-month-old infants represent sequences: Do they track the statistical relations among specific sequence elements (e.g., AB, BC) or do they encode abstract ordinal positions (i.e., B is second)? Infants were habituated to sequences of 4 moving and sounding elements--3 of the elements varied in their ordinal position…

Cognitive performance exhibits patterns of trial-to-trial variation that can be described as 1/f or pink noise, as do repeated measures of locomotor performance. Although cognitive and locomotor performances are known to interact when performed concurrently, it is not known whether concurrent performance affects the tasks' pink noise dynamical…

The "mere exposure effect" refers to the phenomenon where previous exposures to stimuli increase participants' subsequent affective preference for those stimuli. This study explored the effect of selective attention on the mere exposure effect. The experiments manipulated the to-be-attended drawings in the exposure period (either red or green…
