Active control over exploration improves memory in toddlers.
Proc Biol Sci

Department of Cognitive Science, Central European University, Vienna, Austria.
Across two experiments, we implemented a novel gaze-contingent eye-tracking paradigm to investigate the early emergence of memory benefits from active control over exploration and to examine how exploratory behaviours affect memory formation in early development. Toddlers (experiment 1: = 36, 18-36 months; experiment 2: = 41, 23-36 months) were either allowed to actively control their exploration (active condition) or presented with the same information that they could only passively observe (passive condition in experiment 1; yoked condition in experiment 2). They were then tested in a preferential-looking paradigm in which familiar versus novel stimuli were presented in pairs.

Background: Only a small percentage of trauma-exposed subjects develop PTSD, with females being twice as likely. Most rodent models focus on males and fail to account for inter-individual variability in females.
New Method: We tested a behavioral PTSD model in female rats to distinguish between susceptible and resilient individuals.
This study builds upon previous work suggesting food may increase concerns about climate change, even across political ideologies. Previous work examined whether reading about climate impacts on food increased concern about climate change, compared to reading about climate impacts on weather. The current paper goes beyond reading about climate impacts, to explore the potential for food experiences, such as tasting novel ice cream, to increase people's concerns about climate change.

The open field test (OFT) is frequently used in research to assess anxiety-like behavior and locomotor activity. Its simple design can lead to the misconception that it is a standardized procedure comparable between laboratories. However, some modifications in the setup can cause changes in behavior.

Musicians and researchers are creative professions that share many similarities. They both aim to bring joy and progress to humanity. In recent decades, it has been shown that music has the ability to alleviate pain, improve heart function, reduce anxiety, and stimulate the release of endogenous opioids in the brain.
