The authors investigated the individual and relative contributions of different aspects of maternal support (i.e., verbal, affective, and behavioral) in relation to children's collaborative and independent reminiscing. Four-year-old children discussed personal past experiences with their mothers and with a researcher. In collaborative recall with their mothers, children's narrative behavior was regulated best by maternal use of specific elaborative components, such as affirmations. In contrast, in children's independent recall, affective and behavioral qualities of maternal support were related to children's memory performance. Specifically, during free-recall, the dimensions of quality of instruction and respect for autonomy were significant predictors of children's narratives. In the context of prompted recall (supported by wh-questions), respect for autonomy was the only significant predictor of children's involvement in the conversations and of the amount of unique content they provided. The findings suggest that different aspects of maternal behavior facilitate different components of children's reminiscing skills, which children might apply depending on demands of the autobiographical memory conversation.

Rationale: Clinical literature indicates there may be a therapeutic use of cannabidiol (CBD) for stress-related disorders. Preclinical literature remains conflicted regarding the underlying neurobehavioral mechanisms, reporting mixed effects of CBD (increased, decreased, or no effect) on anxiety- and fear-related behaviors. Preclinical data demonstrated that CBD modulates hypothalamus-pituitary-adrenal (HPA) axis gene expression; it is unknown whether CBD changes HPA axis responsivity and how this relates to altered behavior.

The present study investigated the influence of emotional stimuli in the flanker task. In six experiments, separate influences of anticipating and reacting to valence-laden stimuli (affective pictures or facial expressions) on the flanker effect and its sequential modulation (also known as conflict adaptation) were examined. The results showed that there was little evidence that emotional stimuli influenced cognitive control when positive and negative stimuli appeared randomly during the flanker task.

Background: Stress during pregnancy and postpartum periods has been associated with short-term cognitive deficits with potential long-term Alzheimer's disease (AD) risk. However, the biological mechanisms mediating these effects remain poorly understood. This study investigated the impacts of recurrent heat and simulated refugee camp stress across pregnancy and the postpartum period on cognition, affective behaviour, and AD neuropathological changes in primiparous rats.

Background: Alzheimer's disease (AD) is a neurological disorder marked by progressive cognitive decline, memory deficits, and neuronal cell loss (Knopman, 2021). A brain region significantly impacted by the progression of AD is the subiculum, a structure responsible for spatial navigation, cognitive processes, and the modulation of emotional and affective behaviors within the hippocampus (Fanselow and Dong, 2010). Although subiculum cell loss has been well-established as an early indicator of AD (Carlesimo et al.

Background: Exposures to hazardous noise causes irreversible injury to the structures of the inner ear, leading to changes in hearing and balance function with strong links to age-related cognitive impairment. While the role of noise-induced hearing loss in long-term health consequences, such as progression or development of Alzheimer's Disease (AD) has been suggested, the underlying mechanisms and behavioral and cognitive outcomes or therapeutic solutions to mitigate these changes remain understudied. This study aimed to characterize the association between blast exposure, hearing loss, and the progression of AD pathology, and determine the underlying mechanisms.
