Behavioral variability is important for motor skill learning but continues to be present and actively regulated even in well-learned behaviors. In adult songbirds, two types of song variability can persist and are modulated by social context: variability in syllable structure and variability in syllable sequencing. The degree to which the control of both types of adult variability is shared or distinct remains unknown. The output of a basal ganglia-forebrain circuit, LMAN (the lateral magnocellular nucleus of the anterior nidopallium), has been implicated in song variability. For example, in adult zebra finches, neurons in LMAN actively control the variability of syllable structure. It is unclear, however, whether LMAN contributes to variability in adult syllable sequencing because sequence variability in adult zebra finch song is minimal. In contrast, Bengalese finches retain variability in both syllable structure and syllable sequencing into adulthood. We analyzed the effects of LMAN lesions on the variability of syllable structure and sequencing and on the social modulation of these forms of variability in adult Bengalese finches. We found that lesions of LMAN significantly reduced the variability of syllable structure but not of syllable sequencing. We also found that LMAN lesions eliminated the social modulation of the variability of syllable structure but did not detect significant effects on the modulation of sequence variability. These results show that LMAN contributes differentially to syllable versus sequence variability of adult song and suggest that these forms of variability are regulated by distinct neural pathways.

Nowadays, many robotic applications require robots making their own decisions and adapting to different conditions and users. This work presents a biologically inspired decision making system, based on drives, motivations, wellbeing, and self-learning, that governs the behavior of the robot considering both internal and external circumstances. In this paper we state the biological foundations that drove the design of the system, as well as how it has been implemented in a real robot. Following a homeostatic approach, the ultimate goal of the robot is to keep its wellbeing as high as possible. In order to achieve this goal, our decision making system uses learning mechanisms to assess the best action to execute at any moment. Considering that the proposed system has been implemented in a real social robot, human-robot interaction is of paramount importance and the learned behaviors of the robot are oriented to foster the interactions with the user. The operation of the system is shown in a scenario where the robot Mini plays games with a user. In this context, we have included a robust user detection mechanism tailored for short distance interactions. After the learning phase, the robot has learned how to lead the user to interact with it in a natural way.

This chapter provides the in-session activity sheets, homework data sheet, and parent handout for the Generalization and Maintenance Session. This session reviews the concepts of generalization and maintenance. These strategies promote continuation of behavioral changes and the extension of learned behaviors from one context to another.

Rolls shares important data on hunger, thirst, sexuality, and learned behaviors, but is it pertinent to understanding the fundamental nature of emotionality? Important as such work is for understanding the motivated behaviors of animals, Rolls builds a constructivist theory of emotions and primary-process affective consciousness without considering past evidence on specific types of emotional tendencies and their diverse neural substrates.

As a social being, human life continues in communities with other people. Human being is the only entity that communicates with highly complex learned behaviors that include best use of gestures and mimics, advanced reflex and instinct language as well as language. In our study, we wanted to determine the communication skills of university students with their socio-demographic characteristics. Two separate forms were used in the study. The evaluation of the obtained data was done by SPSS (Version 16.0) Statistical Package Program. The target population of the study is composed of students studying at Marmara University. In the direction of the data obtained within the scope of the research it was observed that the communication skills of the students studying in the departments providing health education are higher. University students are encouraged to develop listening skills and create an environment in which they can express themselves better.

This article questions whether social justice can live within the structural racism present in the field of evaluation. Structural racism refers to the totality of ways in which societies foster racial discrimination through mutually reinforcing systems of housing, education, employment, earnings, benefits, credit, media, health care, and criminal justice. In order for social justice to be a professional standard of evaluation, the field must recognize, identify, and modify persistent learned behaviors associated with structural racism. We assert that all evaluators, regardless of demographic designation, are subject to perpetuating structural and institutional racism, found in the history and systems of the profession, by tacitly accepting the status quo norms of evaluation practice. Current norms, policies, and practices compromise the normalization of social justice in evaluation. Evaluators sanctioned and reinforced by their professional association, the American Evaluation Association, have the power to modify behaviors of evaluators that perpetuate social injustice in the discipline and field of professional evaluation. We highlight pioneering literature that intellectually protest and position paradigm shifts for equity. We acknowledge the presence of racial and ethnic colleagues, and professional statements about social justice as confrontations to structural racism found in the history and systems of the evaluation field. Finally, we propose a framework for professional behavior modification as a strategy for the extinction of structural racism in evaluation and assert that social justice can only be realized when structural racism is eradicated.
