Variability And Location Of Movement Endpoint Distributions: The Influence Of Instructions For Movement Speed And Accuracy, Abhishek Dey
Variability And Location Of Movement Endpoint Distributions: The Influence Of Instructions For Movement Speed And Accuracy, Abhishek Dey

An influential theory of motor control predicts that targeted hand movements should be aimed at the target center and that the variability of movement endpoint distributions should fill the target region (Meyer et al., 1988). Because increases in the amount of movement endpoint variability correlates with increases in movement speed (Schmidt et al., 1979), centering the distribution on the target center and expanding variability to the limits of the target boundaries should allow for maximization of movement speed, without the production of movement errors (i.e., target misses). Slifkin and Eder (2016) recently found that those predictions only held over a …

Aging And Emotion Recognition: An Examination Of Stimulus And Attentional Mechanisms, Stephanie Nicole Sedall

Emotion recognition is essential for interpersonal communication. However, previous research has suggested that older adults are not as accurate as younger adults in recognizing certain emotions, particularly negative facial expressions of anger, fear, and sadness. Including additional contextual information (e.g., manipulation of certain facial features) might help us better understand these age differences. The present study investigated how potential age differences in emotion recognition are influenced by stimulus factors (target eye gaze direction) as well as facial viewing patterns, cognitive functioning, and physiological processes. A sample of younger and older adults viewed static facial expressions depicting anger, fear, sadness, happiness, …
An Experimental Test Of Whether Mortality Salience Can Motivate Open-Mindedness Among Individuals With Intrinsic Goal Orientations, Mark Blades
ETD Archive
Terror management theory posits that when people are primed with thoughts of death, they will seek to abide by their cultural worldview beliefs. For example, mortality reminders motivate those with an extrinsic goal orientation to strive to accomplish culturally valued goals (e.g., wealth) and defend familiar cultural worldviews. But, as of yet, no research has investigated the possibility that MS might motivate those with an intrinsic goal orientation to strive instead to explore culturally, socially, or intellectually novel experiences and information. The present research hypothesized that MS would lead individuals with stronger extrinsic goal orientations to defensively prefer their familiar …
