Personality and Politics: Values, Traits, and Political Choice

Voters' political choices have presumably come to depend more on their personal preferences and less on their social characteristics in Western democracies. We examine two aspects of personality that may influence political choice, traits and personal values, using the Five Factor Model of personality traits and the Schwartz (1992 ) theory of basic personal values. Data from 3044 voters for the major coalitions in the Italian national election of 2001 showed that supporters of the two coalitions differed in traits and values, largely as hypothesized. Center-left voters were higher than center-right voters in the traits of friendliness and openness and lower in energy and conscientiousness. Regarding values, center-left voters were higher than center-right voters in universalism, benevolence, and self-direction and lower in security, power, achievement, conformity, and tradition. Logistic regressions revealed that values explained substantial variance in past and future voting and in change of political choice, trumping personality traits. We discuss explanations for the primacy of values and implications for the social cognitive view of personality.     

When Parsimony Subdues Distinctiveness: Simplified Public Perceptions of Politicians' Personality

Voters develop uniquely simplified perceptions of political candidates' personalities during election campaigns. In an earlier study, voters described their own personalities, and also those of celebrities, using the same five factors typical of the Big Five model of personality. In contrast, the appraisal of political candidates' personalities by voters in both Italy and the United States was reduced to only a few factors. The present research extends that exploration of the relationship between personality and politics to the public's perception of politicians' personalities across a wider variety of politicians and across a long time span after an election campaign. Two studies conducted in Italy, with more than 3,000 voters, replicated the earlier results: The factors of Energy and Agreeableness are primary anchors for evaluating politicians' personalities both during campaigns and for several years thereafter. Also uncovered were congruences between the ways that voters tend to present themselves (self-schemata) and the schemata they use to evaluate candidates representing their political preference.     

A model of bidirectional synaptic plasticity: from signaling network to channel conductance

In many regions of the brain, including the mammalian cortex, the strength of synaptic transmission can be bidirectionally regulated by cortical activity (synaptic plasticity). One line of evidence indicates that long-term synaptic potentiation (LTP) and long-term synaptic depression (LTD), correlate with the phosphorylation/dephosphorylation of sites on the alpha-Amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor subunit protein GluR1. Bidirectional synaptic plasticity can be induced by different frequencies of presynaptic stimulation, but there is considerable evidence indicating that the key variable is calcium influx through postsynaptic N-methyl-d-aspartate (NMDA) receptors. Here, we present a biophysical model of bidirectional synaptic plasticity based on [Ca2+]-dependent phospho/dephosphorylation of the GluR1 subunit of the AMPA receptor. The primary assumption of the model, for which there is wide experimental support, is that the postsynaptic calcium concentration, and consequent activation of calcium-dependent protein kinases and phosphatases, is the trigger for phosphorylation/dephosphorylation at GluR1 and consequent induction of LTP/LTD. We explore several different mathematical approaches, all of them based on mass-action assumptions. First, we use a first order approach, in which transition rates are functions of an activator, in this case calcium. Second, we adopt the Michaelis-Menten approach with different assumptions about the signal transduction cascades, ranging from abstract to more detailed and biologically plausible models. Despite the different assumptions made in each model, in each case, LTD is induced by a moderate increase in postsynaptic calcium and LTP is induced by high Ca2+ concentration.     

The disposition-situation debate and research on aggression

Person-situation interaction is considered in the light of a redefinition of the notions of consistency, stability, coherence, and specificity. A research program able to combine the study of individual differences with experimental research in a developmental perspective is recommended. Findings from research on aggression are presented to support this approach.     

Indicators of aggression: The dissipation-rumination scale

Discussion on results of recent studies on Irritability and Emotional Susceptibility scales introduces the presentation of a new scale to study individual differences related to aggressive behavior. The new Dissipation-Rumination Scale results from examining the influence of the interval of time between the instigation and the opportunity to aggress and is related to the inclination to overcome and abandon more or less rapidly feelings of distress and wishes of retaliation associated with the experience of insults suffered. While principal-components analysis confirms the unifactorial structure of the scale with respect to groups of Ss of different language and nationality, results of experimental studies clarify its construct validity.     

Trait congruence in the study of the cognitive consequences of emotional arousal

This study investigated the possible influence of mood and emotional vulnerability on recall. Mood was induced by projecting highly emotionally laden slides. In the first experiment, 64 female subjects, rated low or high on emotional vulnerability, were tested on recall of mood-congruent, mood-incongruent and neutral words, under mood induction and non-mood induction conditions. Emotionally low-vulnerable subjects recalled more mood-congruent than mood-incongruent words in the mood induction condition, whereas the opposite was the case in the non-mood induction condition. Highly vulnerable subjects recalled more mood-congruent than mood-incongruent words in the non-mood induction condition and fewer mood-congruent words in the mood induction compared with non-mood induction condition. The results are discussed in terms of ‘mood congruence’ (to explain low-vulnerable (LV) subjects' performance) and in terms of ‘trait congruence’ (to explain highly-vulnerable (HV) subjects' performance). In a second experiment, which investigated LV and HV subjects' galvanic skin responses to highly- and low-emotionally laden slides, the highest values were those for HV subjects when exposed to emotional slides. The different activation of LV and HV subjects led us to reconsider previous reasoning regarding mood congruence and trait congruence in the light of the inverted U theory.     

Measuring parental and family efficacy beliefs of adolescents' parents: Cross‐cultural comparisons in Italy and Portugal

The goal of this study was to examine the psychometric properties of the Perceived Parental Self‐Efficacy (PPSE) and Perceived Family Collective Efficacy (PFCE) revised scales in the Portuguese and Italian contexts. To this aim two studies were conducted: the first reported the exploratory and confirmatory factor analyses with Portuguese samples, whereas the second addressed the cross‐cultural invariance of PPSE and PFCE (Portugal and Italy). Results of the first study showed the appropriate fit of the unifactorial model of both scales to Portuguese data. The invariance analyses performed in the second study attested to the PPSE and PFCE's configural, metric and scalar invariance in both countries. The correlations of PPSE and PFCE with communication, management of conflict and children's school achievement further attested to their construct and practical validity. Thus, PPSE and PFCE proved to be suitable to further use in research and psychological assessment fields.     

Assessing regulatory emotional self-efficacy in three countries

The Regulatory Emotional Self-Efficacy (RESE) scale was developed to assess perceived self-efficacy in managing negative (NEG) and in expressing positive (POS) affect (G. V. Caprara & M. Gerbino, 2001). In this study of young adults, the factorial structure of the RESE scale was found to be similar in Italy, the United States, and Bolivia. In addition to a factor for POS, NEG was represented by a second-order factor of 2 different negative affects: despondency-distress (DES) and anger-irritation (ANG). Overall, there was partial invariance at both metric and scalar levels across gender and countries. Discriminant and convergent validity of the RESE scale was further examined in the Italian sample. Stronger patterns of association of POS with prosocial behavior, of ANG with low aggressive behavior problems and irritability, and of DES with low anxiety/depressive problems and shyness and high self-esteem were found.     

Reciprocal Relations Among Self-Efficacy Beliefs and Prosociality Across Time

ABSTRACT The present study examined the longitudinal relations between individuals' prosociality and their self-efficacy beliefs in regard to emotional regulation and responding empathically to others' needs. The participants were 244 females and 222 males with a mean age of 17 years ( SD =1.5) at T1, 19 years ( SD =1.4) at T2, and 21 years ( SD =1.6) at T3. The findings corroborated the posited paths of relations assigning empathic self-efficacy a major role in predicting the level of individuals' prosociality. Empathic self-efficacy beliefs mediated the relations of regulative emotional self-efficacy beliefs to prosocial tendencies such as caring, sharing, helping, and empathic concern toward others. The posited conceptual model accounted for a significant portion of variance in prosociality and has implications for interventions designed to promote and sustain prosociality.     

Weight Bias Internalization Scale Discriminates Obese and Overweight Patients with Different Severity Levels of Depression: the Italian Version of the WBIS

We have investigated the psychometric properties of the Italian version of the weight bias internalization scale (WBIS) in overweight and obese patients who were attending weight loss programs. Participants were 386 overweight and obese patients admitted in two medical centers specializing in the treatment of obesity. All the patients were administered the WBIS, and measures of binge eating, depression, self-esteem, and body dissatisfaction. Confirmatory factor analysis failed to confirm the fit of the original 11-item unidimensional model. Item analysis and exploratory factor analysis indicated that 9 items included in the original measure (the items 1 and 9 were excluded because low item-total correlations) formed a reliable unidimensional measure of internalized weight bias (WBIS-9). The WBIS-9 was significantly correlated with convergent measures and was able to categorize individuals with different severity levels of depression (sensitivity of 0.72 and specificity of 0.70). The WBIS-9 may be useful in clinical practice to discriminate patients with more severe psychopathology, comorbid disordered eating patterns, and risk for poor outcomes.
