Adolescents flexibly adapt action selection based on controllability inferences [0.03%]
青少年根据可控性推理灵活适应行为选择

Hillary A Raab et al.
From early in life, we encounter both controllable environments, in which our actions can causally influence the reward outcomes we experience, and uncontrollable environments, in which they cannot. Environmental controllability is theoreti...

Lapses in attention can negatively impact later memory of an experience. Attention and encoding resources are thought to decline as more experiences are encountered in succession, accounting for the primacy effect in which memory is better ...
Prelimbic cortex ensembles promote appetitive learning-associated behavior [0.03%]
前额叶皮层簇促进与食欲行为相关的学习

Memories of prior rewards bias our actions and future decisions. To determine the neural correlates of an appetitive associative learning task, we trained male mice to discriminate a reward-predicting cue over the course of 7 d. Encoding, r...
Evidence for novelty reward cross-cueing in the odor span task in rats: implications for odor-based reward-motivated tasks [0.03%]
在大鼠的气味跨度任务中，对新颖性奖励交叉提示证据的分析：对基于气味的奖励动机任务的启示
Timothy J Onofrychuk,Aiden E Glass,Quentin Greba et al.
Timothy J Onofrychuk et al.
The odor span task (OST) infers working memory capacity (WMC) by requiring rodents to discriminate between previously presented and session-novel odors to obtain a hidden food reward. Here, rats' responses to session-novel odors and food re...
Retrograde amnesia for the stress-induced impairment of extinction: time-dependent and not so forgotten [0.03%]
应激诱导消退抑制的逆向遗忘：一种依赖时间而不是被忘记的现象

James F Briggs
We investigated whether retrograde amnesia for the stress-induced impairment of extinction retrieval shares similar characteristics with original acquisition memories. The first experiment demonstrated that cycloheximide administered shortl...
State-dependent memory retrieval: insights from neural dynamics and behavioral perspectives [0.03%]
基于神经动力学和行为视角的状态依赖性记忆检索

Fei Wang et al.
Memory retrieval is strikingly susceptible to external states (environment) and internal states (mood states and alcohol), yet we know little about the underlying mechanisms. We examined how internally generated states influence successful ...
Hippocampal motor memory network reorganization depends on familiarity, not time [0.03%]
海马运动记忆网络的重构依赖于熟悉程度，而非时间因素

D Gregory Sullens et al.
There is debate as to whether a time-dependent transformation of the episodic-like memory network is observed for nonepisodic tasks, including procedural motor memory. To determine how motor memory networks reorganize with time and practice...
Serial reversal learning in an olfactory discrimination task in 3xTg-AD mice [0.03%]
3xTg-AD小鼠嗅觉辨别任务中的序列逆转学习能力研究

Kyle M Roddick
Male and female 3xTg-AD mice between 5 and 24 mo of age and their B6129F2/J wild-type controls were tested on a series of 18 olfactory discrimination and reversal tasks in an operant olfactometer. All mice learned the odor discriminations a...
Parsing memory and nonmemory contributions to age-related declines in mnemonic discrimination performance: a hierarchical Bayesian diffusion decision modeling approach [0.03%]
基于层次贝叶斯扩散决策模型的方法解析记忆和非记忆因素对记忆辨别表现老化衰退的贡献作用
Caroline Chwiesko,John Janecek,Stephanie Doering et al.
Caroline Chwiesko et al.
The mnemonic discrimination task (MDT) is a widely used cognitive assessment tool. Performance in this task is believed to indicate an age-related deficit in episodic memory stemming from a decreased ability to pattern-separate among simila...
Cue predictiveness and uncertainty determine cue representation during visual statistical learning [0.03%]
线索的预测性和不确定性决定了视觉统计学习过程中的线索表征
Puyuan Zhang,Hui Chen,Shelley Xiuli Tong
Puyuan Zhang
This study investigated how humans process probabilistic-associated information when encountering varying levels of uncertainty during implicit visual statistical learning. A novel probabilistic cueing validation paradigm was developed to p...
