In his now-classic research on inoculation theory, McGuire (1964) demonstrated that exposing people to an initial weak counterattitudinal message could lead to enhanced resistance to a subsequent stronger counterattitudinal message. More recently, research on the valence-framing effect (Bizer & Petty, 2005) demonstrated an alternative way to make attitudes more resistant. Simply framing a perso...

background: adolescence is a sensitive period of acquiring normal and abnormal habits for all of life. the study investigates determinants of responsibility for health, spiritual health and interpersonal relations and predictive factors based on the theory of planned behavior in high school girl students in tabriz.   methods : in this cross-sectional study, 340 students were selected thorough m...

Functional theories of attitudes address why people hold attitudes. The current study had two main goals: to extend the study of attitude functions, and to relate these functions to moral development. One hundred seventy-four participants filled out a revision of Herek's (1987) Attitude Functions Inventory (AFI) and a short form of Rest's (1979) Defining Issues Test (DIT). Factor analysis on th...

The stability of spacecraft attitude is studied with considering sinusoidal disturbance. A passive attitude controller without angular velocity measurement for spacecraft described by quaternion is designed. The passive controller has no information related to system parameters. So it has robustness to model error and uncertainty of model parameters. The stability of spacecraft attitude control...

Small satellites are now capable of performing missions that require accurate attitude determination and control. However, low size, power, and cost requirements limit the types of attitude sensors that can be used on a small craft, making attitude estimation difficult. In particular, star trackers—often the attitude sensors of choice for larger spacecraft—are not practical for small satellites...

It's fitting that my first contribution in the new " Attitude and Behavior " column addresses the age-old question, which comes first-attitude or behavior? Actually, the more practical question is which should be targeted for change first-attitude or behavior? Education typically addresses " attitude " or internal and subjective dimensions of people by attempting to " think people into acting d...

A novel split field of view star tracker is being developed for the EO-3 GIFTS mission (2004). The camera is designed to be autonomously self-calibrating, and capable of a rapid/reliable solution of the lost-in-space problem as well as recursive attitude estimation. Two efficient Kalman filter algorithms for attitude, camera principal point offset, and focal length estimation are developed. The...

The effect of elaboration (i.e., information processing) on attitude strength has been a key prediction of some of the most influential theories of persuasion over the past few decades. This article provides a new look at this relationship. After reviewing support for the notion that structural processes (i.e., knowledge acquisition, structural consistency, and attitude accessibility) drive the...

In this series a pictorial quiz pertaining to identification of normal anatomical structures and landmarks at a given level on the computed tomography (CT) is presented. An image depicting normal anatomy is followed by a series of images showing different pathologies. Readers are expected to identify and appreciate variation and changes in the normal anatomy in presence of a given pathology. Th...

People are able to explicitly resist using knowledge about one person to evaluate another person from the same group. After learning about positive and negative behaviors performed by one individual from each of two different groups, participants were introduced briefly to new individuals from the groups. Implicit evaluations of the original individuals readily generalized to the new individual...
