Visual working memory stores stimuli from our environment as representations that can be accessed by high-level control processes. This study addresses a longstanding debate in the literature about whether storage limits ...

Finite normal mixture modeling is a popular technique for clustering individuals into distinct subpopulations. A characteristic of mixture modeling that researchers may be unaware of is its tendency to arrive at locally, ...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Growth mixture modeling can be used for two purposes: 1) to identify mixtures of normal sub-groups, and 2) to approximate oddly shaped distributions ...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The existence of time-based forgetting has been a controversial topic almost as long as memory has been investigated. In recent years there have been ...

As network data gains popularity for research in various fields, the need for methods to predict future links or find missing links in the data has increased. One subset of the methodology used to solve this problem involves ...

The Random Intercept (RI) factor model is proposed as an alternative to traditional genetic factor models for the analysis of longitudinal twin data. This model constitutes a more factorially complex alternative to the ...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Drinkers report using alcohol when experiencing negative emotions, e.g., "to feel numb" or escape and also in times of celebration, e.g., "to get high" ...

The effects of positive affect (PA) on cognitive outcomes have been studied extensively. These effects map on squarely to a Cognitive-Experiential Self Theory (CEST) framework (Epstein, 1991; 1994). One component of CEST ...

Metabotropic glutamate receptor 5 (mGlu5) has been implicated in a variety of learning processes and is important for aversive learning tasks. The present studies used an mGlu5 receptor positive allosteric modulator, ...

Variation in the gene encoding the dopamine D4 receptor (DRD4) may moderate the influence of environments (i.e., a gene-environment interaction, GXE) on personality traits and motives associated with alcohol use disorders. ...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Metabotropic glutamate (mGlu) receptors are known to mediate learning and memory. Although evidence indicates a role for mGlu receptors (e.g., mGlu5) ...

Two experiments were conducted to examine the mechanisms underlying deficits of visual working memory in Parkinson's disease (PD). One study combined behavioral methods with event-related potentials (ERPs), the other, ...

Previous work with the TgCRND8 mouse model of Alzheimer's disease has shown that voluntary exercise implemented for long time periods (5-months) and starting at very young ages (1-month), prior to the development of disease ...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The abilities to represent and process quantity information exist across many animal species and are evident early in the life of individuals. Preverbal ...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Literature on relationships of emotions to psychological adjustment has mainly focused on unitarily valenced affect (i.e., positive or negative emotions). ...

Researchers have long been interested in the emergence of transitivity (e.g., if A>B and B>C, then A>C). However, it is not clear at what age children start to make transitive inferences successfully. In addition, nonhuman ...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The post-auricular reflex (PAR) is a vestigial microreflex which is thought to be a component of startle. However, unlike prototypical components of ...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Though non-suicidal self-injury (NSSI) and suicidal thoughts and behaviors (STBs) often co-occur, very little is known about the shared and unique ...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The goal of the present research was to assess two lines of Wistar rats selectively bred for high (HVR) and low (LVR) voluntary wheel running, in ...

The obesity epidemic and associated diseases are a direct result of both diet choice and inactivity, as overconsumption of palatable foods and a sedentary lifestyle invariably precede the onset of weight gain. Our laboratory ...
