Social competition stimulates cognitive performance in a sex-specific manner
Social interactions are thought to be a critical driver in the evolution of cognitive ability. Cooperative interactions, such as pair bonding, rather than competitive interactions have been largely implicated in the evolution of increased cognition. This is despite competition traditionally being a very strong driver of trait evolution. Males of many species track changes in their social environment and alter their reproductive strategies in response to anticipated levels of competition. We predict this to be cognitively challenging. Using a Drosophila melanogaster model we are able to distinguish between the effects of a competitive environment versus generic social contact by exposing flies to same-sex same-species competition vs different species partners, shown to pose non-competitive contacts. Males increase olfactory learning/memory and visual memory after exposure to conspecific males only, a pattern echoed by increased expression of synaptic genes and an increased need for sleep. For females, largely not affected by mating competition, the opposite pattern was seen. The results indicate that specific social contacts dependent on sex, not simply generic social stimulation, may be an important evolutionary driver for cognitive ability in fruit flies.
Traffic noise inhibits cognitive performance in a songbird
<p>Noise pollution is commonly associated with human environments and mounting evidence indicates that noise has a variety of negative effects on wildlife. Noise has also been linked to cognitive impairment in humans and because many animals use cognitively-intensive processes to overcome environmental challenges, noise pollution has the potential to interfere with cognitive function in animals living in urban areas or near roads. We experimentally examined how road traffic noise impacts avian cognitive performance by testing adult zebra finches (Taeniopygia guttata) on a battery of foraging tasks in the presence or absence of traffic noise playback. Here we show that traffic noise reduces cognitive performance, including inhibitory control, motor learning, spatial memory, and social learning, but not associative color learning. This study demonstrates a novel mechanism through which anthropogenic noise can impact animals, namely through cognitive interference, and suggests that noise pollution may have previously unconsidered consequences for animals.</p>
Data from: Dietary patterns during adulthood and cognitive performance in midlife: the CARDIA study
Objective: To investigate whether dietary patterns (Mediterranean diet (MedDiet), Dietary Approaches to Stop Hypertension (DASH) and A Priori Diet Quality Score (APDQS)) during adulthood are associated with better midlife cognitive performance. Methods: We studied 2,621 CARDIA participants: 45% black, 57% female, and age 25±3.5 years at baseline (1985-6). Diet scores were calculated from repeated diet history up to year 20. Linear models were used to examine association between tertiles of diet score and year 25 to 30 change in standardized test scores for verbal learning (RAVLT), processing speed (Digit Symbol Substitution Test (DSST)) and executive function (Stroop Interference), and Montreal Cognitive Assessment (MoCA) at year 30. Results: Higher scores in all three diets were associated with less decline in verbal memory (all P<0.01). Higher DASH and APDQS scores were associated with less decline on DSST (DASH: low= -0.05, mid= -0.00, high= 0.06; APDQS: low= -0.07, mid= -0.01, high= 0.07, both PTrend=0.02). Higher MedDiet and APDQS scores were associated with less decline on Stroop interference (MedDiet: low=0.10, mid=-0.06, high=-0.03 and APDQS: low=0.11, mid=0.01, high=-0.10, both PTrend<0.01). Odds ratios (95% confidence interval) for poor global cognitive function (≥1 SD below mean MoCA) comparing extreme tertiles of the three dietary scores were 0.45 (0.33-0.62) for MedDiet, 0.38 (0.26-0.54) for APDQS and 0.88 (0.68-1.15) for DASH. Conclusions: Greater adherence to heart-healthy dietary patterns during adulthood was associated with better midlife cognitive performance. Additional studies are needed to define the combination of foods and nutrients for optimal brain health across the life-course.
Data from: Cognitive performance is linked to group size and affects fitness in Australian magpies
The Social Intelligence Hypothesis argues that the demands of social life drive cognitive evolution. This idea receives support from comparative studies linking variation in group size or mating systems with cognitive and neuroanatomical differences across species, but findings are contradictory and contentious. To understand the cognitive consequences of sociality it is also important to investigate social variation within species. Here we show that in wild, cooperatively breeding Australian magpies, individuals living in larger groups show elevated cognitive performance, which in turn is linked to increased reproductive success. Individual performance was highly correlated across four cognitive tasks, hinting towards a "general intelligence factor" underlying cognitive performance. Repeated cognitive testing of juveniles at different ages showed that the group size – cognition correlation emerged in early life, suggesting that living in larger groups promotes cognitive development. Furthermore, we found a positive association between female task performance and three indicators of reproductive success, thus identifying a selective benefit of greater cognitive performance. Together, these results provide critical intraspecific evidence that sociality can shape cognitive development and evolution.

The OpenFeeder: a flexible automated RFID feeder to measure inter and intraspecies differences in cognitive and behavioral performance in wild birds
<p>Understanding the ecology and evolution of personality and cognition requires the development of new tools to measure individual and species differences in behavioral and cognitive performances in wild populations. Furthermore, such tools should facilitate collection of large sample sizes, evaluate the repeatability of measured traits and allow direct comparison of species performances across a variety of behavioural tasks. Here we present a RFID-based feeder (OpenFeeder) designed to run visual cognitive tasks in wild animals. We illustrate the flexibility of the tool showing performances of three wild passerine species (<em>Parus major</em>, <em>Cyanistes caeruleus</em> and <em>Poecile palustris</em>) in an associative learning task. We recorded performances of a large number of individuals (>300) in the wild and showed both inter and intraspecific differences in associative learning. We also found moderate to high repeatability in individual differences in associative learning in each species. We show that the OpenFeeder is a flexible tool to record performance in multiple cognitive and behavioural tasks in free ranging animals across a variety of passerine species. The design, firmware, and software are open source to facilitate use in a wide variety of species and thus allow continuous improvement of the system and development of new behavioural and cognitive tasks. In doing so, we hope that this tool will be used by a large community of cognitive ecologists and comparative psychologists for both within and across species studies. Furthermore, our system should facilitate replication of results across populations along large-scale environmental gradients to improve our understanding of the role ecology plays in the evolution of cognitive traits.</p>

Trusting Information Systems in Everyday Work Events – Effects on Cognitive Resources, Performance, and Well-being
<p>This dataset contains raw data collected in an online study at the University of Muenster, Germany. The study is part of a larger research project and examined trust in information systems' associations with users' cognitive resources, performance, and well-being within everyday working events, making use of the event reconstruction method (Grube et al., 2008). It further investigated the moderating influence of contextual conditions of the usage event (i.e., users' accountability and workplace distractions), as well as user-related factors. Data collection was divided into two studies: a pre-study in which user-related factors (disposition to trust technology, technology competence, need for cognition, conscientiousness, need forcontrol) were collected; and a main study within which subjects were asked to put themselves back into their last information system usage event using the event reconstruction method and to indicate their trust in the system, assumed outcomes, as well as perceptions of accountability and workplace distractions.</p>
