Frequency correlates in grapheme-color synaesthesia

Individuals with synaesthesia experience certain stimuli in more than one sensory modality. Most common is the linkage of letters and digits (graphemes) to colors. Whereas synaesthesia might be partly genetically determined, the linkages to specific colors are assumed to be learned. We present a systematic statistical analysis of synaesthetic color perception based on subjects' reproduction of individual colors for each grapheme, instead of simple verbal categorizations. The statistical analysis revealed that the color perceptions, measured with the HSL (hue, saturation, and luminance) scale, varied systematically among the different digits and letters. The frequencies of the digits and letters (in the German language) partly explained these systematic variations. However, digit frequency was more strongly related to color perception in the synaesthetes than was letter frequency. The results for digit and letter frequency indicate that experience with graphemes may shape synaesthetic color perception.     

The simplicity of politicians' personalities across political context: An anomalous replication

Modern politics is becoming increasingly personalized. The personal qualities of political candidates, in fact, account for a considerable amount of the variance in the candidate preference of voters, often more than the political issues in their electoral programs. Despite the emphasis that both the media and campaign leaders place on the ways in which the personalities of politicians are portrayed, people tend to view the personalities of politicians in remarkably simple ways. Here we show that, although people tend to use five personality dimensions to characterize their own personalities, they rely upon only two dimensions to characterize the personalities of politicians. This finding holds across countries (i.e., Italy and the US), and across political figures (i.e., Prodi and Berlusconi in Italy, and Bush and Kerry in the US). The two factors obtained from evaluations of Prodi, Berlusconi, and Kerry were respectively a blend of Energy/Extraversion and Openness and a blend of Friendliness, Conscientiousness, and Emotional Stability. The two factors obtained from evaluations of the US president, though, were respectively a blend of Openness, Conscientiousness, and Friendliness, and a blend of Energy/Extraversion, Emotional Stability, and Friendliness. Thus, the present study is novel in suggesting that while the personalities of politicians may be reduced by voters, they are not always reduced to the same basic factors. Alternative explanations of this “simplification effect” are discussed.     

Motion, emotion and empathy in esthetic experience

The implications of the discovery of mirroring mechanisms and embodied simulation for empathetic responses to images in general, and to works of visual art in particular, have not yet been assessed. Here, we address this issue and we challenge the primacy of cognition in responses to art. We propose that a crucial element of esthetic response consists of the activation of embodied mechanisms encompassing the simulation of actions, emotions and corporeal sensation, and that these mechanisms are universal. This basic level of reaction to images is essential to understanding the effectiveness both of everyday images and of works of art. Historical, cultural and other contextual factors do not preclude the importance of considering the neural processes that arise in the empathetic understanding of visual artworks.     

Exploring classical conditioning for strengthening the links between semantic and lexical representations in pure anomia: Preliminary findings from a single case study

The same language symptom might arise at different functional loci in people with aphasia. Therefore, it is plausible that different therapeutic interventions should be adopted to approach the same difficulties in different patients. Although this point of view is still widely accepted, recently the focus has shifted from the functional locus of a rehabilitative intervention to the mechanisms of action underlying the relearning process. We maintain that both aspects should be taken into account when programming a rehabilitative intervention; furthermore, investigating relearning mechanisms might shed new light on the functional architecture of the disrupted processes. Here, we investigated, in a single case study, whether classical conditioning was a suitable relearning paradigm for targeting word‐finding difficulties in pure anomia, that is in a patient with an impairment in accessing intact output lexical representations from a spared semantic system. Using a word‐repetition task on picture presentation, we contrasted a condition in which the stimulus onset asynchrony between word and picture stimuli was well suited to produce classical conditioning with a condition in which repetition training could not benefit from this learning mechanism. Only classical conditioning training exerted a significant, long‐lasting effect on our patient's naming skill. Tentative implications of our results for the functional architecture of single‐word processing are discussed.     

“Cuts in Action”: A High‐Density EEG Study Investigating the Neural Correlates of Different Editing Techniques in Film

In spite of their striking differences with real‐life perception, films are perceived and understood without effort. Cognitive film theory attributes this to the system of continuity editing, a system of editing guidelines outlining the effect of different cuts and edits on spectators. A major principle in this framework is the 180° rule, a rule recommendation that, to avoid spectators’ attention to the editing, two edited shots of the same event or action should not be filmed from angles differing in a way that expectations of spatial continuity are strongly violated. In the present study, we used high‐density EEG to explore the neural underpinnings of this rule. In particular, our analysis shows that cuts and edits in general elicit early ERP component indicating the registration of syntactic violations as known from language, music, and action processing. However, continuity edits and cuts‐across the line differ from each other regarding later components likely to be indicating the differences in spatial remapping as well as in the degree of conscious awareness of one's own perception. Interestingly, a time–frequency analysis of the occipital alpha rhythm did not support the hypothesis that such differences in processing routes are mainly linked to visual attention. On the contrary, our study found specific modulations of the central mu rhythm ERD as an indicator of sensorimotor activity, suggesting that sensorimotor networks might play an important role. We think that these findings shed new light on current discussions about the role of attention and embodied perception in film perception and should be considered when explaining spectators’ different experience of different kinds of cuts.     

Association of Positivity with Health Problems in Old Age: Preliminary Findings from Spanish Middle Class Seniors

Previous studies have indicated positivity as a basic trait which lies at the very heart of self-esteem, life satisfaction, and dispositional optimism, and predisposes people to view life and experience from a positive point of view. The present research addresses the extent to which age, positivity and its abovementioned expressions may be associated with healthy functioning in old age. Fifty-one men and eighty-one women, all Spanish, predominantly middle-class and educated, in good health and ranging in age from 62 to 80, participated in this research project. The findings reveal the role positivity plays in moderating the negative impact of aging on health problems as assessed by availing of the Nottingham Health Profile. The higher the positivity, the less people seem inclined to report health problems as they advance in age. Self-esteem, life satisfaction, and optimism too show similar effects, but only the association between life satisfaction, health problems and aging were worth considering, once positivity was kept under control.     

Positivity: The Dispositional Basis of Happiness

The present study examined in a stringent developmental model whether positivity, conceptualized as a pervasive mode of appraising, viewing, and perceiving life from a positive stance, predicts chronic positive affectivity across time or vice versa. Participants [263 participants (47 % males)], aged 15.5 at the beginning of the study and 23.5 at the end, reported on measures of positivity and dispositional positive affect four times. Longitudinal findings corroborated the posited paths of relations, with positivity significantly predicting positive affectivity across time rather than vice versa.     

Transfer of training for two ball-throwing tasks

The effects of training overhand ball throws to enhance underhand ball-throwing accuracy were studied with 921 Italian high school pupils (575 girls, M age = 16.5 yr., SD = 1.3; 346 boys, M = 16.5 yr., SD = 1.2) ages 14 to 18 years. A standardized test (10 underhand tennis-ball throws into the floor area delimited by an 80-cm radius wooden hoop lying on the floor 9 m from the standing pupil) was performed and scored. An Experimental group (435 girls, M age = 16.5 yr., SD = 1.3; 204 boys, M age = 16.5 yr., SD = 1.2) was randomly selected to participate in 10 weekly training periods. The set included 10 overhand throws of a rubber bouncing ball (14.5 cm diameter, weight 240 g) into a basketball hoop from 5 standardized positions (in front of the basketball hoop; at 45 degrees, 90 degrees on the right and on the left of the basketball hoop) at a distance of 4.40 m. The underhand test was repeated for both groups. On the average, boys obtained higher test scores than girls of the same age. Older adolescents had higher mean scores than younger adolescents. After 10 weeks, boys and girls of all ages improved. Mean differences between sessions were significant for the Experimental group (Student t test, p < .01). In Session 2, consistent differences between Experimental and Control groups were also found (Student t test, p < .05).     

Personalities of politicians and voters: unique and synergistic relationships

A rare collection of personality assessments from 103 Italian politicians revealed predictable patterns of contrasts and similarities with personality dimensions from a large normative sample (N = 4,578). Three modal personality characteristics distinguished politicians, with their significantly higher levels of Energy, Agreeableness, and Social Desirability, from the general public. Comparability between politicians and the public existed on dimensions of Emotional Stability, Conscientiousness, and Openness (Big Five Questionnaire assessment). Politicians from rival coalitions differed on several dimensions; center-right was higher than center-left in Energy and Conscientiousness. Congruencies emerged between politicians and voters for their coalition on all personality dimensions, except that center-left politicians were higher in Energy than center-left voters, and center-right politicians were higher than voters in both Energy and Agreeableness.
