The present study explores the effects of social-media messages that are presented in television content. In particular, the retention of content and changes in attitude through watching television programs was investigated. Thirty participants were randomly assigned to one of two conditions: one that included social-media messages and one that omitted socialmedia messages. The participants’ ey...

Positive attitude is thought to impact academic achievement and learning in children, but little is known about its underlying neurocognitive mechanisms. Using a large behavioral sample of 240 children, we found that positive attitude toward math uniquely predicted math achievement, even after we accounted for multiple other cognitive-affective factors. We then investigated the neural mechanism...

This study examines how different types of information processing routes influence a user’s attitude toward an Enterprise Resource Planning (ERP) system based on the Elaboration Likelihood Model. We tested the main effects of content quality (central route) and system credibility (peripheral route) on attitude change and the moderating effects of motivation and IT ability. Using student survey ...

This paper presents a method for on-orbit calibration of photodiodes for sun sensing in an attitude determination system. The calibration estimates the scale factors and alignment angles of the photodiodes, resulting in higher attitude determination accuracy than achieved with the pre-flight calibration parameters. The calibration is implemented with an extended Kalman filter to simultaneously ...

Social vigilantism (SV) is an enduring individual difference that assesses the tendency of individuals to impress and propagate their "superior" beliefs onto others to correct others' more "ignorant" opinions. After establishing a reliable measure of SV, three studies showed that SV was associated with greater expressions of belief superiority (whether reacting to others holding dissimilar or s...

In the attitude attribution paradigm, observers must estimate the true attitude of an author who was assigned to advocate a particular position. Observers’ tendency to attribute an attitude in line with the expressed position despite its having been assigned is called the correspondence bias. While there is strong evidence that such attributions are externally invalid, it is less clear whether ...

This article explores the relation of age to manifestations and antecedents of attitude strength. Three studies demonstrate that susceptibility to attitude change is greater during early and late adulthood than during middle adulthood. Three additional studies demonstrate that attitude importance, certainty, and perceived quantity of attitude-relevant knowledge are greater in middle adulthood t...

In this paper, a new algorithm is developed for attitude estimation using Global Positioning System (GPS) signals. The new algorithm is based on a predictive filtering scheme designed for spacecraft without rate measuring devices. The major advantage of this new algorithm over traditional Kalman filter approaches is that the model error is not assumed to represented by an unbiased Gaussian nois...

Introduction: The Joint Milli-Arcsecond Pathfinder Survey 1 (JMAPS) is a Department of the Navy space astrometry mission to conduct an all-sky, bright star astrometric and spectrophotometric survey. The primary goal of the mission is to update the bright star catalog currently used by Department of Defense, NASA, and commercial star tracker manufacturers for spacecraft attitude determination. S...

In this paper we present a PID+ backstepping controller, as a solution to the problem of coordinated attitude control in spacecraft formations. The control scheme is based on quaternions and modified Rodriguez parameters as attitude representation of the relative attitude error. Utilizing the invertibility of the modified Rodriguez parameter kinematic differential equation, a globally exponenti...
