In 2014, 20% of the 4th graders had an unsatisfactory evaluation in the national exam of Portuguese language. This percentage is similar in the 6th and 9th grades indicating that a large number of Portuguese students have reading difficulties. The e-learning platform “I’m still learning” was developed to provide a systematic intervention with students (from 1st to 4th grade) experiencing reading difficulties. This free access platform provides a set of didactic sequences to promote phonological awareness, word reading, reading fluency and comprehension. Informal tasks for reading assessment are also included. In this paper we describe the platform and the theoretical framework adopted in its construction.
Psychopathic traits and reinforcement learning under acute stress
Publication . Carvalheiro, Joana; Conceição, Vasco A.; Mesquita, Ana; Seara‐Cardoso, Ana
Objective: Individuals with high levels of psychopathic traits are often characterized by aberrant reinforcement learning. This type of learning, which implicates making choices that maximize rewards and minimize punishments, may be affected by acute stress. However, how acute stress affects reinforcement learning in individuals with different levels of psychopathic traits is not well-understood. Here, we investigated whether and how individual differences in psychopathic traits modulated the impact of acute stress on reward and punishment learning.
Method: Sixty-two male participants from a university sample completed the Self-Report Psychopathy-Short Form scale and performed a reinforcement-learning task involving monetary gains and losses whilst under acute stress and control conditions.
Results: Individual differences in psychopathic traits modulated the impact of acute stress on behavioral performance toward obtaining gains, but not toward avoiding losses. As levels of psychopathic traits increased, the impairing effect of acute stress on reward learning decreased. Specifically, acute stress impaired performance toward seeking gains to a larger extent in individuals with lower levels of psychopathic traits than in individuals with higher levels of these traits.
Conclusions: Our study indicates that psychopathic traits modulate the impact of acute stress on reward learning.
