Role of stiffness in weight perception

Abstract:  Here, we focused on a load-on task to clarify the judgment mechanism for weight perception. We measured hand trajectory and surface electromyography to estimate time-varying stiffness and torque patterns in joints. Our results showed that the goal of learning motor skills under load-on tasks is to maintain the hand position, and that humans produce force with cocontraction and increasing stiffness levels according to the weight of an object. Finally, we examined whether stiffness is an effective parameter as an efferent signal for weight perception and found that stiffness plays an important role in weight perception.     

CAMPAIGN COMMUNICATION AND ATTITUDE CHANGE: A MULTIDIMENSIONAL ANALYSIS1

The processes by which political attitude changes occur have been examined extensively from a variety of methodological and theoretical perspectives. In this study, the authors attempt to extend the traditional balance formulation to a continuously-scaled least-squares paradigm in which change occurs as a function of accumulated information. A longitudinal tracking of the changes in attitude toward parties, candidates, and issues is used to make predictions about subsequent attitudes and consequent voting behavior. Possible communicative influences from a political campaign are explored with regard to their impact on changes in concept relations. Analysis of political changes hypotheses and a critical examination of the methodology are used as the basis for suggesting improvements in campaign communication research.     

COMMUNICATION PATTERNS OF FOREIGN IMMIGRANTS IN THE PROCESS OF ACCULTURATION1

This paper reports the theoretical development and testing of a causal model of communication patterns of foreign immigrants in the process of acculturation. Communication patterns are conceptualized on two levels: cognitive and behavioral. The cognitive level is observed by the complexity of an immigrant's perception of the host society; the behavioral level by the immigrant's involvement in the host society through interpersonal and mass communication. Three causal factors are identified as major determinants of the immigrant's communication patterns: language competence, acculturation motivation, and accessibility to host communication channels. The theory consists of nine propositions which explain the relationship among the three causal factors, behavioral participation in host communication channels, and cognitive structure in perceiving the host society. The theory was tested and supported by a survey among 400 randomly selected Korean immigrants in the Chicago area.     

Queerness,Disability, and The Vagina Monologues

This paper questions the connection between vaginas and feminist embodiment in The Vagina Monologues and considers how the text both challenges and reinscribes (albeit unintentionally) systems of patriarchy, compulsory heterosexuality, and ableism. I use the Intersex Society of North America's critique as a point of departure and argue that the text offers theorists and activists in feminist, queer, and disability communities an opportunity to understand how power operates in both dominant discourses that degrade vaginas and strategies of feminist resistance that seek to reclaim and celebrate them.
