Associative priming effects can be obtained with masked nonword primes or with masked pseudohomophone primes (e.g., judpe-COURT, tode-FROG), but not with visible primes. The usual explanation is that when the prime is visible, these stimuli no longer activate the semantic representations of their base words. Given the important role of transposed-letter stimuli (e.g., jugde) in visual word recognition, here we examined whether or not an associative priming effect could be obtained with visible transposed-letter nonword primes (e.g., jugde-COURT) in a series of lexical decision experiments. Results showed a sizable associative priming effect with visible transposed-letter nonword primes (i.e., jugde-COURT faster than neevr-COURT) in Experiments 1-3 that was close to that with word primes. In contrast, we failed to find a parallel effect with replacement-letter nonword primes (Experiment 2). These findings pose some constraints to models of visual word recognition.

The small abalone (Haliotis diversicolor) is an economic shellfish cultured in the south coast of China. In recent years, the frequent occurrence of the disease has led to significant mortality in abalone farms. Deleted in malignant brain tumors 1 (DMBT1), a member of the scavenger receptor cysteine-rich (SRCR) protein family, plays an important role in host defense.

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.

Article Synopsis
- - The proposed computational model aims to explain how infants around 18 months develop their understanding of language by looking at two main aspects: taxonomic priming (grouping similar words) and associative priming (linking words that frequently occur together).
- - Taxonomic priming is linked to semantic feature overlap, while associative priming is explained through Hebbian links based on word co-occurrence.
- - The model addresses why taxonomic priming appears later than associative priming, suggesting that feature overlap emerges as infants learn, and it successfully replicates data from experiments examining how the timing between words affects these priming effects.

Article Synopsis
- Dopamine signaling in the amygdala is crucial for associative learning, particularly in linking environmental cues to the effects of drugs like cocaine.
- Researchers used chemogenetics to alter dopamine inputs from the ventral tegmental area (VTA) to the basolateral amygdala (BLA) during cocaine-related behaviors, revealing that inhibiting dopamine reduced the motivation to seek cocaine when exposed to previously associated cues.
- The findings suggest that targeting dopamine pathways in the amygdala could lead to new treatments for substance use disorders by potentially modifying the associations formed between cues and drug use.

Article Synopsis
- Mussels, particularly the "duck mussel" A. anatina, are analyzed as bioarchives for monitoring trace elements like Rare Earth Elements and Yttrium (REY) in freshwater systems, specifically from the Danube and Vistula Rivers.
- The study found that mussels showed similar REY patterns across different tissues and shells, with no significant impact from anthropogenic gadolinium (Gd) contamination linked to MRI contrast agents, suggesting limited bioavailability of this contaminant in freshwater.
- Results indicate that mussels preferentially uptake lighter REY, but overall concentrations are comparable to or lower than their food sources, allowing mussel shells to be effective indicators of environmental REY levels without substantial interference from biological
