Any interaction with another person requires some judgement of their characteristics from a short amount of time. Each day a person can interact with many individuals and quick judgments have to be made in each situation to decide how to act or react. This means a person can make hundreds...
Nanostars have many potential applications, particularly in biomedicine, such as drug delivery, detection assays, and even cancer treatment. Seeing how their plasmon changes in response to changes to the environment of the nanostars can give us an insight to the stability of the nanostars. Our current studies involve the effect...
Past research has shown that individual's word usage can reveal aspects of who they are and how they behave (Tausczik & Pennebaker, 2010). For instance, couples who use inclusive pronouns such as “we,” as opposed to singular pronouns such as "I" cope better in relationships (Moran, 2018). Further, the use...
Do freshmen achieve less of their personal and academic short-term goals in comparison to upperclassmen?
Some may intuitively assume that due to age, or lack of experience, college freshmen would have lower perceived task-specific ability (self-efficacy) and actually achieve less (goal-completion ranging from 0% to 100%). Differences between various class-standing...
In current nanotoxicology research, there is a lack of standardization in reporting of zebrafish exposure media and sonication practices. This lack of standardization in use and reporting methods has made reproducing nanoparticle (NP) toxicity results between labs a common issue. It is important to have a standardized way of reporting...

In Experiment 1, participants first rated their familiarity with 6 male celebrities. They then performed dual tasks in which Task 1 required a tone/noise discrimination. For...
Symbioses are intimate interactions between two different organisms. In a pathogenic interaction, one organism benefits and the other is generally harmed; whereas in a mutualistic interaction, the members reciprocally benefit. Rhodococcus is a genus of Gram-positive bacteria that persist in a variety of terrestrial and aquatic ecosystems. Although better known...
Previous research has suggested that how a task is framed can have a significant impact on subsequent performance. These effects seem to be especially important in educational settings where learners are already self-conscious about their likelihood to succeed. Difficult subjects have shown to cause cognitive disequilibrium when confronting dead ends...
The science of how people interact socially with robots is still fairly young. One area of ongoing study is how people figure out the way the robot works -- that is, form a "mental model" of the robot. We are especially ignorant of how this happens over time, starting with...

Consuming cruciferous vegetables such as broccoli sprouts, kale, Brussels sprouts, and bok choy is associated with several health benefits, such as a decreased risk of certain cancers. Cruciferous vegetables contain the glucosinolate, glucoraphanin (GFN). Cutting, chopping or chewing these vegetables releases the enzyme myrosinase, which transforms GFN into sulforaphane (SFN)....
During volcanic eruptions ascending magma undergoes decompression, resulting in a decrease of dissolved H2O. This creates unstable conditions for the hydrous mineral amphibole. As a result a reaction rim forms from anhydrous minerals such as pyroxene, plagioclase, and Fe-Ti oxides (Rutherford and Hill, 1993). There have been numerous studies done...
Alexithymia is a trait where individuals have difficulty identifying feeling and finding a word to express emotion. Some studies have suggested that this deficit is due to dissociation (repression), or an inability to perceive emotions, whereas others argued that the deficit is due to suppression of emotional information after it...
Previous studies have suggested that LEET words can automatically activate lexical information because of their physical similarity to real words (e.g., Perea, Duñabeitia, & Carreiras, 2008). Lien, Allen, and Martin (in press) recently used electrophysiological measures (event-related brain potentials; ERPs) to show similar lexical/semantic activation (based on the N400 effect,...
