background: hiv/aids is known to affect an individual not only physically but also mentally, socially, and financially. it is a syndrome that builds a vacuum in a person affecting his/her life as a whole. nowadays, using anti-viral medication delays the onset of the disease cycle and increases the patients’ life time. from the psychological point of view, however, such patients are faced with a...

Predicting a transition point in behavioral data should take into account the complexity of the signal being influenced by contextual factors. In this paper, we propose to analyze changes in the embedding dimension as contextual information indicating a proceeding transitive point, called OPtimal Embedding tRANsition Detection (OPERAND). Three texts were processed and translated to time-series ...

The shy-bold continuum is a fundamental axis of behavioral variation in humans and at least some other species, but its taxonomic distribution and evolutionary implications are unknown. Models of optimal risk, density- or frequency-dependent selection, and phenotypic plasticity can provide a theoretical framework for understanding shyness and boldness as a product of natural selection. We sketc...

An essential characteristic of human behavior is the ability to act out of intrinsic motivation to achieve desired goals. These kinds of actions have been classed as intentional or voluntary. They contrast with actions that are performed in response to external stimuli. Recent research has begun to explore the functional underpinnings of internally guided actions and how they differ from extern...

This study examined the relationships between the approach-avoidance dimension, as well as the mastery-performance dimension of achievement goals, implicit theory of intelligence, and behavioral regulations among engineering students in a polytechnic in the academic domain. Polytechnic students (n = 1359) from Singapore participated in the survey. They were assessed on achievement goal orientat...

It is commonly accepted that reward is an effective motivator of behavior, but little is known about potential costs resulting from reward associations. Here, we used functional magnetic resonance imaging (fMRI) to investigate the neural underpinnings of such reward-related performance-disrupting effects in a reward-modulated Stroop task in humans. While reward associations in the task-relevant...
