Reflections on the recent history and the present challenges of personality psychology

The recent history of personality psychology is rapidly reviewed with the aim of indicating significant cues of the progress which has taken place and of the problems which are still pending. In this regard, a three-stage model of progress provides the arguments which introduce personality psychology into the domain of ‘complexity’. Readmission of individual differences in the investigation of basic processes, attention to marginal perturbances in between non-significant deviations, and use of circumplex models to make sense of multiple facets of phenomena are indicated as viable avenues to the complexity of personality psychology.     

Time processing impairments in preschoolers at risk of developing difficulties in mathematics

The occurrence of time processing problems in individuals with Development Dyscalculia (DD) has favored the view of a general magnitude system devoted to both numerical and temporal information. Yet, this scenario has been partially challenged by studies indicating that time difficulties can be attributed to poor calculation or counting skills, which can support reasoning on time in school‐aged children and adults. Here, we tackle this debate by exploring the performance of young children before they fully develop the symbolic number system. Preschoolers at risk of developing DD were compared with typically developing children in a series of tasks investigating time processing and in their ‘sense of time’, evaluated by parents and teachers. Results yielded a poorer performance in time reproduction of 5‐second intervals and in time discrimination, as well as a weaker ‘sense of time’, in children at risk of DD. These findings provide evidence of a common magnitude system that would be responsible for deficits in both numerical and temporal domains, already at early stages of life.     

Short-term effects of a multi-disciplinary cardiac rehabilitation programme on psychological well-being, exercise capacity and weight in a sample of obese in-patients with coronary heart disease: a practice-level study

Given that many patients referred to cardiac rehabilitation (CR) are obese, diet therapy, exercise training, nutritional and psychological counselling for both obesity and psychological distress should be included as important components in all CR programmes. In this practice-level, observational study we evaluated the short-term within-group effects of a four-week multi-factorial inpatient CR programme specifically addressed to weight loss, fitness improvement and psychological health increase on 176 obese in-patients with coronary heart disease (CHD). Outcome measures were exercise capacity measured with estimated metabolic equivalents (METs), body mass index (BMI) and psychological well-being (PGWBI). Results show statistically significant improvements in all the PGWBI sub-scales and total score, except in general health (p = 0.393). No moderation effects were found for BMI class, age, diabetes and ejection fraction (EF). METs significantly increased by 30.3% (p < 0.001) and BMI decreased by 1.37 points (p < 0.001). Significant correlations were found between BMI and weight reductions with PGWBI anxiety and total score improvements. This multi-disciplinary CR programme including diet therapy, exercise training and psychological counselling provides indication for short-term within-group effectiveness on functional exercise capacity, BMI and PGWBI in a sample of obese in-patients with CHD. However, controlled studies are needed to corroborate the results we found.     

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.     

Influence of training on maintenance of equilibrium on a tilting platform

To assess the influence of training on the maintenance of equilibrium on a tilting platform, 13 young healthy male athletes aged 19 to 33 years were randomly divided into experimental (n=7) and control (n=6) groups. Two experimental sessions were performed before and after a specific 4-wk. training by the experimental group. Subjects stood upright on a tilting platform. The athletes were asked to maintain the platform as horizontal as possible during a 30-sec. test. The three-dimensional movements of the platform versus the ground were recorded by using a computerized optoelectronic digitiser. The platform plane was calculated and its directrix computed. The area of oscillation and instantaneous angular velocity of the directrix at standardized height were calculated. In both groups the area of oscillation and the angular velocity were reduced in Session 2, but the reduction was significant only in the experimental group. Specific training can significantly improve skill at maintaining equilibrium in young healthy sport performers.     

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.     

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.     

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.     

Investigation of age and gender effects on positive orientation in Italian twins

We investigated age and gender effects on “Positive Orientation” (POS)—an individual's tendency to view life with a positive outlook—using a genetically informed design. Study subjects were 1016 twins aged 22–75 from the Italian twin registry. We assessed POS by the recently developed P‐scale. First, we used confirmatory factor analysis to investigate scale's measurement invariance by age and gender. Then, we applied biometric modelling to estimate genetic and environmental components of POS score. Overall, we found a satisfactory degree of measurement invariance by both age and gender. Results from these analyses further indicated an increasing mean level of POS across the lifespan. Additive genetic and unshared environmental factors explained respectively 58% and 42% of variance in POS score, with no significant gender differences; furthermore, the pattern of change of gene‐environment architecture of POS over time was consistent with a greater plasticity of personality at older ages.
