Who did what?: age-related differences in memory for people and their actions
(University of Missouri--Columbia, 2006)
The associative-deficit hypothesis (ADH), proposed by Naveh-Benjamin (2000), holds that the decline in episodic memory that accompanies aging is at least partially due to an inability to bind single units of information into more complex units...
Age differences in memory for names : the effect of pre-learned semantic associations
(University of Missouri--Columbia, 2010)
The present experiments investigated whether participants could use basic semantic information about a person (i.e., a "mediator"), such as an occupation, to help link that person's name to his or her face. In each of three experiments, older...
Use of multimodal stimuli to facilitate associative memory in older adults
(University of Missouri--Columbia, 2019)
attempted to extend these results by using multimodal stimuli to improve perception in older adults in order to reduce their associative deficit. In Experiment 1 older and younger adults were presented with unrelated word pairs in visual, audio...
Eye-tracking investigations of lexical ambiguity
(University of Missouri--Columbia, 2005)
The visual world paradigm was used to investigate the time course of ambiguity resolution. Typically, the visual stimuli consisted of one picture that was semantically related to the dominant meaning of an ambiguous word, ...
Alcohol consumption, executive function and risky decision making
(University of Missouri--Columbia, 2009)
, or an alcohol beverage (1.0 g/kg ethanol). They then engaged in a laboratory cognitive control (flanker) task while their EEG (electroencephalogram) was recorded. This research suggests that effects of alcohol on the relationship between neural measures...
Assessing the role of pair familiarity in the associative deficit of older adults
(University of Missouri--Columbia, 2009)
adults to capitalize on their intact familiarity in order to accurately remember pairings of information. Experiments 1 and 2 investigated this by unitizing two components of a pair such that the color information enables certain pairings to appear as one...
Maintaining cross-domain objects and features in working memory : implications for storage in models of working memory
(University of Missouri--Columbia, 2007)
of the influential multiple component model (2000), but it is still unknown how this new component interacts with better-known working memory components. Using cross-domain objects (letters in spatial locations) for memoranda, the following experiments aimed to learn...
CDPPB reverses an NMDA receptor antagonist-induced deficit in inhibitory avoidance and conditioned taste aversion learning in rats
(University of Missouri--Columbia, 2010)
Rats administered a metabotropic glutamate receptor 5 (mGluR5) positive allosteric modulator (PAM), CDPPB, and/or an NMDA receptor antagonist, MK-801, were given inhibitory avoidance or conditioned taste aversion training. ...
Low sensitivity to, and craving for, alcohol in naturalistic and laboratory settings
(University of Missouri--Columbia, 2019)
highly sought after in their own right. Psychophysiological laboratory work has produced promising results that suggest that this process is stronger for low sensitivity drinkers relative to their higher sensitivity peers. The present work attempts...
Paying attention to binding: is the associative deficit of older adults mediated by reduced attentional resources?
(University of Missouri--Columbia, 2005)
). The present experiments investigated whether such a binding deficit is mediated by a reduction of attentional resources by using a dual task procedure where participants were asked to study lists of words while completing an auditory reaction time task...
Forgetting in short term memory : the effect of time
(University of Missouri--Columbia, 2008)
Forgetting in short-term memory has been studied extensively and yet no consensus has emerged to explain its cause. Two theories continue to provide competing explanations of forgetting in short-term memory: decay and ...
Effects of deep brain stimulation on implicit learning in patients with Parkinson's disease
(University of Missouri--Columbia, 2009)
related feedback to drive learning during stimulation. In contrast, motor and pre-motor activation improved during DBS. In study two, parallel rule based and information integration tasks were used to examine if DBS impairs accurate response selection thru...
Dopamine and emotion processing in schizotypal anhedonia
(University of Missouri--Columbia, 2009)
Three studies examined emotion processing and dopamine regulation in anhedonia. In Study 1, in multiple assessments of emotional experience (e.g., naturalistic and lab contexts and social and nonsocial situations), people with elevated social...
An evolutionary perspective of the effects of emotion on the post-auricular reflex
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The post-auricular reflex (PAR), contrary to other components of the startle reflex, is potentiated by positive emotions and inhibited by negative ...
A transdiagnostic investigation of amygdala-vmPFC resting state functional connectivity and emotional distress in daily lives
(University of Missouri--Columbia, 2018)
Mood disorders, anxiety disorders and borderline personality disorder overlap in symptom criteria, are highly comorbid with one another, and group together in factor models of psychopathology (Kotov et al., 2011). These ...
Lucky to be alive : scarcity effects on evaluation of life
(University of Missouri--Columbia, 2010)

Examining bidirectional associations between momentary impulsivity, alcohol consumption, and daily life contexts
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI--COLUMBIA AT REQUEST OF AUTHOR.] Longitudinal, cross sectional, and laboratory studies have examined the relationships between impulsivity and alcohol use. However, most studies so far have...
The relationship between cortisol and social stress in late adolescent girls' friendships
(University of Missouri--Columbia, 2007)
The potential mechanisms linking early experience and temperament to coping with common peer dynamics and the stress hormone cortisol were explored for young women in two studies. Girls and women typically use friendships, specifically dyadic self...
Individual differences affect hormonal responses to a team-based violent videogame competition, but not in solitary play
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Testosterone and cortisol were assessed along with various personality measures in response to a violent videogame competition in three different ...
Affective instability and impulsivity in borderline personality disorder
(University of Missouri--Columbia, 2006)
Affective instability and impulsivity are primary features of borderline personality disorder (BPD). We examined the effect of an interaction between these features, represented by FFM analogues of negative affectivity and ...
