Article Abstract
Previous research has shown that the picture superiority effect (PSE) is seen in tests of associative recognition for random pairs of line drawings compared to pairs of concrete words (Hockley, 2008). In the present study we demonstrated that the PSE for associative recognition is still observed when subjects have correctly identified the individual items of each pair as old (Experiment 1), and that this effect is not due to rehearsal borrowing (Experiment 2). The PSE for associative recognition also is shown to be present but attenuated for mixed picture-word pairs (Experiment 3), and similar in magnitude for pairs of simple black and white line drawings and coloured photographs of detailed objects (Experiment 4). The results are consistent with the view that the semantic meaning of nameable pictures is activated faster than that of words thereby affording subjects more time to generate and elaborate meaningful associations between items depicted in picture form.

A matter of complexity? The role of the dorsal posterior parietal cortex in processing changes in spatial information across time.
Behav Neurosci

Department of Psychology and Program in Neuroscience, Providence College.
The posterior parietal cortex (PPC) is an associative neocortical region that integrates multiple streams of information and is implicated in spatial cognition and decision making. In some cases, however, the PPC is not required for these functions. One possibility is that the PPC is recruited when spatial complexity is high.

Article Synopsis
- Prior familiarity with faces, especially when they are known US celebrities, enhances recognition and source memory compared to unfamiliar European celebrities.
- In two experiments, both familiar and unfamiliar faces showed improved recognition rates with repetition during learning, but participants were more accurate with familiar faces.
- Experiment 2 revealed that while familiar faces were recognized more frequently, they were also more prone to being incorrectly identified as previously seen when paired with new backgrounds, suggesting complexities in face memory recall.
Recollection-related fMRI effects in entorhinal cortex predict longitudinal memory change in healthy older adults.

The present study examines whether structural and functional variability in medial temporal lobe (MTL) neocortical regions correlate with individual differences in episodic memory and longitudinal memory change in cognitively healthy older adults. To address this question, older adults were administered a battery of neuropsychological tests on three occasions: the second occasion one month after the first test session, and a third session three years later. Structural and functional MRI data were acquired between the first two sessions and included an in-scanner associative recognition procedure enabling estimation of MTL encoding and recollection fMRI BOLD effects.

Recognition protects biological systems at all scales, from cells to societies. Social insects recognize their nestmates by colony-specific olfactory labels that individuals store as neural templates in their memory. Throughout an ant's life, learning continuously shapes the nestmate recognition template to keep up with the constant changes in colony labels.

Article Synopsis
- The study investigates polymorphic genomic inversions in the spruce bark beetle (Ips typographus), a significant forest pest in Europe, examining their prevalence and role in local adaptation.
- Researchers analyzed 240 individuals across 18 populations, identifying 27 polymorphic inversions that account for ~28% of the genome, revealing a complex genomic landscape influenced by recombination and overlap.
- The findings suggest that these inversions may be maintained by neutral processes rather than traditional evolutionary mechanisms, and they are notably enriched in genes related to odorant receptors, highlighting their potential impact on traits linked to ecological interactions.
