Creativity and dementia: a review

In these last years, creativity was found to play an important role for dementia patients in terms of diagnosis and rehabilitation strategies. This led us to explore the relationships between dementia and creativity. At the aim, artistic creativity and divergent thinking are considered both in non-artists and artists affected by different types of dementia. In general, artistic creativity can be expressed in exceptional cases both in Alzheimer's disease and Frontotemporal dementia, whereas divergent thinking decreases in dementia. The creation of paintings or music is anyway important for expressing emotions and well-being. Yet, creativity seems to emerge when the right prefrontal cortex, posterior temporal, and parietal areas are relatively intact, whereas it declines when these areas are damaged. However, enhanced creativity in dementia is not confirmed by controlled studies conducted in non-artists, and whether artists with dementia can show creativity has to be fully addressed. Future research directions are suggested.     

Individual reactions to a multisensory immersive virtual environment: the impact of a wind farm on individuals

The aim of this study was to assess the impact of a wind farm on individuals by means of an audio-visual methodology that tried to simulate biologically plausible individual-environment interactions. To disentangle the effects of auditory and visual components on cognitive performances and subjective evaluations, unimodal (Audio or Video) and bimodal (Audio + Video) approaches were compared. Participants were assigned to three experimental conditions that reproduced a wind farm by means of an immersive virtual reality system: bimodal condition, reproducing scenarios with both acoustic and visual stimuli; unimodal visual condition, with only visual stimuli; unimodal auditory condition, with only auditory stimuli. While immersed in the virtual scenarios, participants performed tasks assessing verbal fluency, short-term verbal memory, backward counting, and distance estimations (egocentric: how far is the turbine from you?; allocentric: how far is the turbine from the target?). Afterwards, participants reported their degree of visual and noise annoyance. The results revealed that the presence of a visual scenario as compared to the only availability of auditory stimuli may exert a negative effect on resource-demanding cognitive tasks but a positive effect on perceived noise annoyance. This supports the idea that humans perceive the environment holistically and that auditory and visual features are processed in close interaction.     

The representation of conceptual knowledge: visual,auditory, and olfactory imagery compared with semantic processing

Two experiments comparing imaginative processing in different modalities and semantic processing were carried out to investigate the issue of whether conceptual knowledge can be represented in different format. Participants were asked to judge the similarity between visual images, auditory images, and olfactory images in the imaginative block, if two items belonged to the same category in the semantic block. Items were verbally cued in both experiments. The degree of similarity between the imaginative and semantic items was changed across experiments. Experiment 1 showed that the semantic processing was faster than the visual and the auditory imaginative processing, whereas no differentiation was possible between the semantic processing and the olfactory imaginative processing. Experiment 2 revealed that only the visual imaginative processing could be differentiated from the semantic processing in terms of accuracy. These results showed that the visual and auditory imaginative processing can be differentiated from the semantic processing, although both visual and auditory images strongly rely on semantic representations. On the contrary, no differentiation is possible within the olfactory domain. Results are discussed in the frame of the imagery debate.     

Audiotactile temporal order judgments

We report a series of three experiments in which participants made unspeeded 'Which modality came first?' temporal order judgments (TOJs) to pairs of auditory and tactile stimuli presented at varying stimulus onset asynchronies (SOAs) using the method of constant stimuli. The stimuli were presented from either the same or different locations in order to explore the potential effect of redundant spatial information on audiotactile temporal perception. In Experiment 1, the auditory and tactile stimuli had to be separated by nearly 80 ms for inexperienced participants to be able to judge their temporal order accurately (i.e., for the just noticeable difference (JND) to be achieved), no matter whether the stimuli were presented from the same or different spatial positions. More experienced psychophysical observers (Experiment 2) also failed to show any effect of relative spatial position on audiotactile TOJ performance, despite having much lower JNDs (40 ms) overall. A similar pattern of results was found in Experiment 3 when silent electrocutaneous stimulation was used rather than vibrotactile stimulation. Thus, relative spatial position seems to be a less important factor in determining performance for audiotactile TOJ than for other modality pairings (e.g., audiovisual and visuotactile).     

Organizational identification as a trigger for personal well-being: Associations with happiness and stress through job outcomes

Recent literature highlights that well-being, happiness, as well as personal stress, has become important for guiding public policy in areas that might involve suboptimal behaviour. Positive life outcomes can extend from one field of life (family, work, sport, children, hobbies, etc.) to another, multiplying success, performance, and health. In the present study, we aimed to verify whether the positive relation between organizational identification and employees' experiences then extends also into a positive association with more general well-being that is unrelated to the work context. For this purpose, we considered two proxies of organizational well-being: job satisfaction (on the positive side) and turnover intention (on the negative side) as well as the distal associations with happiness. The study involved 305 workers who completed a questionnaire made up of five scales: organization identification, job satisfaction, turnover intention, happiness, and personal stress. We found that organizational identification is positively related to employees' job satisfaction and negatively related to their intention to leave. Afterwards, job satisfaction and turnover intention were related to personal stress and happiness, suggesting a positive effect of organizational identification above and beyond the work context.     

Can Creativity Predict Cognitive Reserve?

Cognitive reserve relies on the ability to effectively cope with aging and brain damage by using alternate processes to approach tasks when standard approaches are no longer available. In this study, the issue if creativity can predict cognitive reserve has been explored. Forty participants (mean age: 61 years) filled out: the Cognitive Reserve Index questionnaire, the Torrance Test of Creative Thinking in visual and verbal form, Raven's Progressive Matrices (PM38), and the Verbal Judgments Test. The analysis revealed that all indices of verbal creativity were positively correlated with indices of cognitive reserve, except with cognitive reserve related to working activity. However, using the composite score of verbal creativity, all indices of cognitive reserve were predicted, including the index related to working activity. These results show that verbal creativity could be considered as another proxy indicator of cognitive reserve, and open to the hypothesis that verbal creativity enhances cognitive reserve and sustains active aging.     

For a philosophy of comparisons: the problems of comparative studies in relation with Daoism

This paper reflects on the problems of cross-cultural interpretations and translations analysing how these are rooted in theories and philosophical assumptions. Inquiring the concept of philosophy per se, the paper discusses key passages of Heidegger and the related problem of 有 (you) and 無 (wu). The conclusion is that to translate such terms, it is necessary to revise the coercive onto-theological assumptions of metaphysics. This can trigger a process of re-grounding grounds with the consequent possibility of language transformation, which, in turn, activates new relations between cultural diversities. Thus, philosophy itself becomes an eminently comparative dialogue between cultures. Without setting a single method for all these problems, the paper argues that comparisons themselves call for necessarily different methodological approaches. Hence, whilst Daoism helps to illuminate these issues defining one of the possibilities that a philosophy of comparisons entails, this same reasoning opens a way for another reading of the Daodejing.     

Persistence of Traumatic Symptoms After Seven Years: Evidence from Young Individuals Exposed to the L’Aquila Earthquake

In this article, we investigated the presence of trauma-induced sequelae in a sample of 41 young individuals exposed to the L’Aquila earthquake who did not seek mental help in the aftermath of the disaster or in the ensuing months. We compared this group with 43 individuals, matched for age and education, who had not experienced an earthquake but had moved to and lived in L’Aquila after the earthquake and thus experienced the challenges of living in an earthquake-struck city. This study aimed to show that earthquake-exposed individuals scored significantly higher than nonexposed persons on certain scales of the Trauma Symptom Inventory (TSI) seven years after the event. Our results indicated that exposed individuals exhibited higher scores on the dissociation, intrusive experience, and defensive avoidance scales. Furthermore, a correlational analysis between specific conditions detected by the Earthquake Checklist L’Aquila (ECLA) and the TSI identified the influences of specific conditions, such as being trapped or injured under rubble during the earthquake, experiencing a persistent fear of aftershocks or a life-threatening feeling, and witnessing the death of a loved one. All of these experiences resulted in the persistence of trauma-related symptoms. Dissociative experiences during the trauma, cognitive and behavioral avoidance and reexperiencing were associated with negative effects and may hinder the natural process of recovery in trauma-exposed individuals. Knowledge of mid- and long-term psychological difficulties following a traumatic event may be useful for promoting interventions in mental health across exposed populations.     

On the nature of nonverbal working memory fractionation: a case of selective spatial short-term memory deficit in a child

Several lines of research on adult subjects demonstrate a visual/spatial fractionation of nonverbal working memory (WM), while behavioral studies on normal children support the idea of a static/dynamic distinction. In the present paper, we report a child (Z.M.) who failed on nonverbal WM tasks. To verify the nature of his defect, we carried out two experiments: in Experiment 1, Z.M. failed on spatial WM tasks but not on visual WM tasks and was not affected by the static/dynamic format of stimulus presentation; in Experiment 2, this visual/spatial dissociation was extended to the imagery domain. These results are best accounted for within the visual/spatial fractionation of WM and confirmed the role of WM in mental imagery. Clinical and rehabilitative implications of the present findings are also discussed.
