AI Article Synopsis
- Adolescence can be a time of strong positive and negative feelings that affect how we remember things and react to what we see around us.
- A study looked at how these strong negative feelings (like bad smells) help teens and adults remember the things connected to those feelings better than things that didn't have those connections.
- Both teens and adults showed they remembered the bad-smell items better and that their emotional reactions during learning helped improve their memory for those items.
Article Abstract
Adolescence is often filled with positive and negative emotional experiences that may change how individuals remember and respond to stimuli in their environment. In adults, aversive events can both enhance memory for associated stimuli as well as generalize to enhance memory for unreinforced but conceptually related stimuli. The present study tested whether learned aversive associations similarly lead to better memory and generalization across a category of stimuli in adolescents. Participants completed an olfactory Pavlovian category conditioning task in which trial-unique exemplars from one of two categories were partially reinforced with an aversive odor. Participants then returned 24 h later to complete a recognition memory test. We found better corrected recognition memory for the reinforced versus the unreinforced category of stimuli in both adults and adolescents. Further analysis revealed that enhanced recognition memory was driven specifically by better memory for the reinforced exemplars. Autonomic arousal during learning was also related to subsequent memory. These findings build on previous work in adolescent and adult humans and rodents showing comparable acquisition of aversive Pavlovian conditioned responses across age groups and demonstrate that memory for stimuli with an acquired aversive association is enhanced in both adults and adolescents.

The burnout phenomenon is a subject of considerable interest due to its impact on both employee well-being and scientific inquiry. Workplace factors, both intrinsic and extrinsic, play a pivotal role in its development, often leading to job dissatisfaction and heightened burnout risk. Chronic stress and burnout induce significant dysregulation in the autonomic nervous system and hormonal pathways, alongside structural brain changes.

This study is aimed at evaluating the neurotoxic effects of chronic exposure of sodium fluoride (NaF) in developmental stages in rat using prenatal models. NaF (100 ppm, orally) dosing via drinking water was given to pregnant rats in disease group. In the treatment groups, Metformin & Dehydrozingerone (DHZ) (200 mg/kg) were administered orally along with NaF, and the dosing was continued throughout the gestation and lactation periods to the pups until the end of experiment.

Objective: Social cognition is defined as the ability to construct mental representations about oneself, others, and one's relationships with others to guide social behaviors, including referring to mental states (cognitive factor) and understanding emotional states (affective factor). Difficulties in social cognition may be symptoms of schizophrenia. The authors examined associations between two factors of social cognition and specific schizophrenia symptoms, as well as a potential path from low-level affective perceptual social cognition to high-level social cognition, which may be associated with schizophrenia symptoms.

Background: Moral distress is reported to be a critical force contributing to intensifying rates of anxiety, depression and burnout experienced by healthcare workers. In this paper, we examine the moral dilemmas and ensuing distress personally and collectively experienced by healthcare workers while caring for patients during the pandemic.
Methods: Data are drawn from free-text responses from a cross-sectional national online survey of Australian healthcare workers about the patient care challenges they faced.
A shared serial order system for verbal working memory and language production: evidence from aphasia.

Many aspects of human performance require producing sequences of items in serial order. The current study takes a multiple-case approach to investigate whether the system responsible for serial order is shared across cognitive domains, focusing on working memory (WM) and word production. Serial order performance in three individuals with post-stroke language and verbal WM disorders (hereafter persons with aphasia, PWAs) were assessed using recognition and recall tasks for verbal and visuospatial WM, as well as error analyses in spoken and written production tasks to assess whether there was a tendency to produce the correct phonemes/letters in the wrong order.
