Climate Change and Emotions: Analysis of People's Emotional States in Southern Ecuador.

Climate change involves multiple emotional expressions associated with specific labels, notably: 'concern,' 'guilt,' or 'scepticism.' However, there are other types of emotions that have been less analysed, such as 'powerlessness,' 'anger' and 'confusion' that are of equal importance for predicting behavioural changes toward this climatic issue. Likewise, few studies in this research field rely on qualitative data to understand and identify the causative agents for the emotional arousal.

Early human communication helps in understanding language evolution.

Building a theory on extant species, as Ackermann et al. do, is a useful contribution to the field of language evolution. Here, I add another living model that might be of interest: human language ontogeny in the first year of life.

Investigating the musical qualities of early infant sounds.

Early vocalizations in Italian and Moroccan infants are examined and the results presented.

Decoding of emotional expressions in children and adolescents.

The aim of this study was to assess whether different kinds of emotions are decoded in different ways during ontogeny. 151 normal subjects (80 boys; 71 girls) aged 8 to 16 were recruited in primary, secondary (middle), and high schools and 46 slides (3 male; 3 female) from Picture of Facial Affect showing six basic emotions were stimuli. Analysis showed that boys and girls in all age groups did not differ in decoding facial expression; happiness and disgust had the highest percentage scores in all age groups, 99% and 94%, respectively, while sadness and fear had the lowest percentage scores, 69% and 55%, respectively.

Newborns crying in different contexts: discrete or graded signals?

The aim of this study was to investigate whether human infants' cries show individually and contextually discriminable acoustic parameters. 20 full-term normal human newborns (aged 1 to 4 days) had their cries recorded during routine blood withdrawal (pain context) 30 min. before a scheduled feeding (hunger context) and when subjected to kinetic stimuli during neurological examination (manipulation context).
