A new model of sensorimotor coupling in the development of speech

We present a computational model that learns a coupling between motor parameters and their sensory consequences in vocal production during a babbling phase. Based on the coupling, preferred motor parameters and prototypically perceived sounds develop concurrently. Exposure to an ambient language modifies perception to coincide with the sounds from the language. The model develops motor mirror neurons that are active when an external sound is perceived. An extension to visual mirror neurons for oral gestures is suggested.     

Social perception of the Spanish law for young offenders

The implementation of the law 5/2000 for the regulation of Criminal Responsibility for Minors has led to a change in interventions in cases of juvenile offenders. This law promotes the educational and rehabilitative aims of the measures imposed. However, the focus of the media on the most serious cases has generated considerable alarm in society in general. The aim of this study is to determine the social perception of Law 5/2000. For this purpose, a sample of 936 people from the Autonomous Region of the Canary Islands was surveyed. The main results indicate that there is a significant lack of knowledge about the law and that people tend to think that the measures taken are not as effective as studies carried out in connection with this subject have shown. Nevertheless, the people surveyed are more in favour of educational measures than of measures that penalize. These results are discussed in connection with the importance that community factors have in dealing with juvenile delinquency, and in particular, in the power of social pressure to modify legislation, and of the community to assume responsibility for the reinsertion of juvenile offenders.     

Career Counseling and Vocational Psychology in Portugal: A Political Perspective

In this article, we present an overview of the political context of vocational psychology and career counseling in Portugal. The essence of our position is that career counseling needs to encompass all the major tasks of personal and social development, beyond the traditional focus on primarily vocational/occupational goals. Given the importance of social and political factors that are apparent in an analysis of the Portuguese climate within career development, we propose that vocational psychology must go beyond a conceptualization of vocational behavior and intervention based on a person–environment fit model and must try to enhance strategies for the development of persons in a broader sense. We further propose that we need to provide career counseling not only at critical decision points, but throughout the life-span, and should not focus merely on occupational details, but on all matters of the development of the person as a whole. Finally, we suggest a perspective on career counseling and vocational psychology that is more responsive to our cultural and historical context and which is sensitive to the reality of a new political era in Portugal.     

Resilience and vagal tone predict cardiac recovery from acute social stress

Previous studies showed that heart period decreases during and recovers after an acute stress. We investigated if individual predispositions and emotional priming influence heart period recovery after a speech stress task. Psychometric scales and resting cardiac vagal tone were used to measure individual traits. The presentation of a sequence of either pleasant or unpleasant pictures, as emotional primers, preceded the speech stress. Heart period was measured throughout the experiment. Stress induced tachycardia irrespective of emotional priming or traits. In the recovery period, participants with higher resting cardiac vagal tone or presenting higher resilience significantly reduced the heart acceleration. Furthermore, these traits interacted synergistically in the promotion of the recovery of heart period. Pleasant priming also improved recovery for participants with lower negative affect. In conclusion, the stress recovery measured through heart period seemed dependent upon individual predispositions and emotional priming. These findings further strengthen previous observations on the association between greater cardiac vagal tone and the ability to regulate emotion.     

Means to an end: Neotropical parrots manage to pull strings to meet their goals

Although parrots share with corvids and primates many of the traits believed to be associated with advanced cognitive processing, knowledge of parrot cognition is still limited to a few species, none of which are Neotropical. Here we examine the ability of three Neotropical parrot species (Blue-Fronted Amazons, Hyacinth and Lear’s macaws) to spontaneously solve a novel physical problem: the string-pulling test. The ability to pull up a string to obtain out-of-reach food has been often considered a cognitively complex task, as it requires the use of a sequence of actions never previously assembled, along with the ability to continuously monitor string, food and certain body movements. We presented subjects with pulling tasks where we varied the spatial relationship between the strings, the presence of a reward and the physical contact between the string and reward to determine whether (1) string-pulling is goal-oriented in these parrots, (2) whether the string is recognized as a means to obtain the reward and (3) whether subjects can visually determine the continuity between the string and the reward, selecting only those strings for which no physical gaps between string and reward were present. Our results show that some individuals of all species were able to use the string as a means to reach a specific goal, in this case, the retrieval of the food treat. Also, subjects from both macaw species were able to visually determine the presence of physical continuity between the string and reward, making their choices consistently with the recognition that no gaps should be present between the string and the reward. Our findings highlight the potential of this taxonomic group for the understanding of the underpinnings of cognition in evolutionarily distant groups such as birds and primates.
