Personalizing politics: a congruency model of political preference

Modern politics become personalized as individual characteristics of voters and candidates assume greater importance in political discourse. Although personalities of candidates capture center stage and become the focus of voters' preferences, individual characteristics of voters, such as their traits and values, become decisive for political choice. The authors' findings reveal that people vote for candidates whose personality traits are in accordance with the ideology of their preferred political party. They also select politicians whose traits match their own traits. Moreover, voters' traits match their own values. The authors outline a congruency model of political preference that highlights the interacting congruencies among voters' self-reported traits and values, voters' perceptions of leaders' personalities, politicians' self-reported traits, and programs of favored political coalitions.     

Body sway during quiet standing: is it the residual chattering of an intermittent stabilization process?

This paper reviews different approaches for explaining body sway while quiet standing that directly address the instability of the human inverted pendulum. We argue that both stiffness control [Winter, D. A., Patla, A. E., Riedtyk, S., & Ishac, M. (2001). Ankle muscle stiffness in the control of balance during quiet standing. Journal of Neurophysiology, 85, 2630-2633] and continuous feedback control by means of a PID (Proportional, Integral, Derivative) mechanism [Peterka, R. J. (2000). Postural control model interpretation of stabilogram diffusion analysis. Biological Cybernetics, 83, 335-343.] can guarantee asymptotic stability of controlled posture at the expense of unrealistic assumptions: the level of intrinsic muscle stiffness in the former case, and the level of background noise in the latter, which also determines an unrealistic level of jerkiness in the sway. We show that the decomposition of the control action into a slow and a fast component (rambling and trembling, respectively, as proposed by [Zatsiorsky, V. M., & Duarte, M. (1999). Instant equilibrium point and its migration in standing tasks: Rambling and trembling components of the stabilogram. Motor Control, 4, 185-200; Zatsiorsky, V. M., & Duarte, M. (2000). Rambling and trembling in quiet standing. Motor Control, 4, 185-200.]) is useful but must be modified in order to take into account that rambling is not a stable equilibrium trajectory. We address the possibility of a form of stability weaker than asymptotic stability in light of the intermittent stabilization mechanism outlined by [Loram, I. D., & Lakie, M. (2002a). Human balancing of an inverted pendulum: position control by small, ballistic-like, throw and catch movements. Journal of Physiology, 540, 1111-1124.], and propose an indicator of intermittent stabilization that is related to the phase portrait of the human inverted pendulum. This indicator provides a further argument against the plausibility of PID-like control mechanisms. Finally, we draw attention to the sliding mode control theory that provides a useful theoretical framework for formulating realistic intermittent, stabilization models.     

The emergence of a shared action ontology: building blocks for a theory

To have an ontology is to interpret a world. In this paper we argue that the brain, viewed as a representational system aimed at interpreting our world, possesses an ontology too. It creates primitives and makes existence assumptions. It decomposes target space in a way that exhibits a certain invariance, which in turn is functionally significant. We will investigate which are the functional regularities guiding this decomposition process, by answering to the following questions: What are the explicit and implicit assumptions about the structure of reality, which at the same time shape the causal profile of the brain's motor output and its representational deep structure, in particular of the conscious mind arising from it (its "phenomenal output")? How do they constrain high-level phenomena like conscious experience, the emergence of a first-person perspective, or social cognition? By reviewing a series of neuroscientific results and integrating them with a wider philosophical perspective, we will emphasize the contribution the motor system makes to this process. As it will be shown, the motor system constructs goals, actions, and intending selves as basic constituents of the world it interprets. It does so by assigning a single, unified causal role to them. Empirical evidence demonstrates that the brain models movements and action goals in terms of multimodal representations of organism-object-relations. Under a representationalist analysis, this process can be conceived of as an internal, dynamic representation of the intentionality-relation itself. We will show how such a complex form of representational content, once it is in place, can later function as a functional building block for social cognition and for a more complex, consciously experienced representation of the first-person perspective as well.     

Cerebellar ataxia: quantitative assessment and cybernetic interpretation

To assess neuromotor disorders clinicians often rely on rating scales. Unfortunately, these scales lack the sensitivity and accuracy needed to detect the small changes in motor coordination that reflect the clinical progression of the disease on the basis of which treatment programmes can be adjusted. As a contribution to this topic, the present paper proposes a straightforward kinematic and kinetic analysis of reaching movements of patients with cerebellar ataxia in conjunction with a cybernetic interpretation of the data. The aim of the approach is to capture key deficits in the underlying motor control processes. We suggest that cerebellar ataxia may be characterized by defective feedforward control.     

Personality Profiles and Political Parties

This paper explores relationships between basic personality profiles of voters and their political party preferences. The Italian political system has moved recently from previously extreme, ideologically distinctive parties to form complex coalitions varying around more centrist orientations. Significant evidence was found for the utility of the Five-Factor Model of Personality in distinguishing between voters' expressed preferences, even given this greater subtlety in proposed values and agendas. More than 2,000 Italian voters who self-identified as having voted for new center-left or center-right political coalitions differed systematically in predicted directions on several personality dimensions measured by the Big Five Questionnaire. In the context of the model, center-right voters displayed more Energy and slightly more Conscientiousness than center-left voters, whose dominant personality characteristics were Agreeableness (Friendliness) and Openness; Emotional Stability was unrelated to either group. This relationship between individual differences in personality and political preferences was not influenced by the demographic variables of voters' gender, age, or education. Thus, personality dimensions proved to be stronger predictors of political preference than any of these standard predictor variables. Implications are discussed regarding links among personality, persuasion, power, and politics.     

Naming the parents of the THOG: Mental representation and reasoning

It was hypothesized that subjects misrepresent the THOG problem by confusing data and hypotheses. An abstract version of the problem in which the given exemplars and the hypothetical ones were designated by two different labels was used in three experiments. Experiment 1 showed that this version elicits a better performance than the standard version of the problem. Experiments 2 and 3 confirmed these results, by ruling out a possible alternative account of the facilitatory effect obtained in Experiment 1. The present results are discussed in relationship to the general issues of content effects and non-consequentialism in reasoning.     

Understanding the Complexity of Human Aggression: Affective,Cognitive, and Social Dimensions of Individual Differences in Propensity Toward Aggression

Human aggression is a complex phenomenon operating at multiple levels. Converging evidence distinguishes ‘hot’ aggression, impulsive and emotionally-centered, from ‘cool’ aggression, cognitively based and instrumental. The correspondence of these aggressive response patterns with individual differences in Propensity toward Aggression was investigated. Our data (from 477 Italian adults) map ten of these aggression indicators into the personality space defined by the Five-Factor Model (FFM) of personality. The quadrant containing most of these variables is defined by Emotional Instability (the negative pole of Emotional Stability) and Hostility (the negative pole of Friendliness). Factor analysis uncovered two factors that accounted for nearly 60 percent of the variance in Propensity toward Aggression: Emotional Responsivity and Positive Evaluation of Violence. Practical implications for issues of health and disease, violence, and interventions for different forms of adults' and children's aggression are outlined.     

Chances and frequencies in probabilistic reasoning: rejoinder to Hoffrage,Gigerenzer, Krauss,and Martignon

Do individuals unfamiliar with probability and statistics need a specific type of data in order to draw correct inferences about uncertain events? Girotto and Gonzalez (Cognition 78 (2001) 247) showed that naive individuals solve frequency as well as probability problems, when they reason extensionally, in particular when probabilities are represented by numbers of chances. Hoffrage, Gigerenzer, Krauss, and Martignon (Cognition 84 (2002) 343) argued that numbers of chances are natural frequencies disguised as probabilities, though lacking the properties of true probabilities. They concluded that we failed to demonstrate that naive individuals can deal with true probabilities as opposed to natural frequencies. In this paper, we demonstrate that numbers of chances do represent probabilities, and that naive individuals do not confuse numbers of chances with frequencies. We conclude that there is no evidence for the claim that natural frequencies have a special cognitive status, and the evolutionary argument that the human mind is unable to deal with probabilities.     

When Likeness Goes with Liking: The Case of Political Preference

Three studies show that people tend to vote for politicians (i.e., either Romano Prodi or Silvio Berlusconi in Italy or George W. Bush or John Kerry in the United States) whose traits they rate as being most similar to their own. People perceived higher similarity between themselves and political figures with respect to traits that were most distinctive of each platform and their respective leaders. These findings, while corroborating the similarity-attraction relationship, further attest to the role that personal characteristics of both voters and candidates play in orienting political preference.
