A systematic review of animal personality in conservation science.

Although animal personality research may have applied uses, this suggestion has yet to be evaluated by assessing empirical studies examining animal personality and conservation. To address this knowledge gap, we performed a systematic review of the peer-reviewed literature relating to conservation science and animal personality. Criteria for inclusion in our review included access to full text, primary research articles, and relevant animal conservation or personality focus (i.e., not human personality studies). Ninety-two articles met these criteria. We summarized the conservation contexts, testing procedures (including species and sample size), analytical approach, claimed personality traits (activity, aggression, boldness, exploration, and sociability), and each report's key findings and conservation-focused suggestions. Although providing evidence for repeatability in behavior is crucial for personality studies, repeatability quantification was implemented in only half of the reports. Nonetheless, each of the 5 personality traits were investigated to some extent in a range of conservations contexts. The most robust studies in the field showed variance in how personality relates to other ecologically important variables across species and contexts. Moreover, many studies were first attempts at using personality for conservation purposes in a given study system. Overall, it appears personality is not yet a fully realized tool for conservation. To apply personality research to conservation problems, we suggest researchers think about where individual differences in behavior may affect conservation outcomes in their system, assess where there are opportunities for repeated measures, and follow the most current methodological guides on quantifying personality.

Aunque la investigación sobre la personalidad animal puede tener usos aplicados, esta propuesta aún no ha sido evaluada mediante el análisis de estudios empíricos que examinan la personalidad animal y la conservación. Realizamos una revisión sistemática de la literatura revisada por pares relacionada con las ciencias de la conservación y la personalidad animal para abordar este vacío en el conocimiento. Los criterios para la inclusión dentro de nuestra revisión incluyen el acceso al texto completo, artículos de investigación primaria y un enfoque relevante en la conservación animal o en la personalidad (es decir, no estudios sobre la personalidad humana). Noventa y dos artículos cumplieron con estos criterios y de ellos resumimos los contextos de conservación, procedimientos de análisis (incluyendo el tamaño de la muestra y de la especie), estrategia analítica, características declaradas de la personalidad (actividad, agresión, audacia, exploración y sociabilidad) y los hallazgos más importantes de cada reporte y sus sugerencias enfocadas en la conservación. Aunque proporcionar evidencias para la repetitividad en el comportamiento es crucial para los estudios de personalidad, la cuantificación de la repetitividad sólo se implementó en la mitad de los reportes. Sin embargo, cada una de las cinco características de la personalidad se investigaron hasta cierto punto dentro de una gama de contextos de la conservación. Los estudios más sólidos en el campo mostraron varianza en cómo la personalidad se relaciona con otras variables de importancia ecológica a través de las especies y los contextos. Además, muchos estudios fueron los primeros intentos del uso de la personalidad con propósitos de conservación en un sistema dado de estudios. En general, parece que la personalidad todavía no es una herramienta completamente realizada para la conservación. Para poder aplicar la investigación sobre la personalidad a los problemas de conservación, sugerimos que los investigadores piensen en dónde pueden afectar las diferencias individuales en el comportamiento a los resultados de la conservación dentro de su sistema, evalúen en dónde hay oportunidades para repetir medidas y sigan las guías metodológicas más actuales sobre la cuantificación de la personalidad.

Primary Care Treatment Integrating Motivation and Exposure for PTSD Symptoms and Hazardous Alcohol Use: A Case Series.

Symptoms of posttraumatic stress disorder (PTSD) and hazardous alcohol use are highly comorbid. Research on integrated interventions to address PTSD symptoms and hazardous alcohol use concurrently has demonstrated efficacy, yet integrated treatments are underutilized. Both patient (e.g., stigma, scheduling/logistics) and clinician (e.g., concern about symptom exacerbation and/or treatment dropout) barriers may impede utilization of integrated interventions among those with comorbid PTSD symptoms and hazardous alcohol use. Primary care behavioral health models (PCBH), in which embedded behavioral health providers deliver treatment to individuals with mild or moderate behavioral health symptoms in primary care, may help address treatment barriers by offering accessible behavioral health interventions in a destigmatizing setting. This paper presents two case examples from a randomized controlled trial testing the efficacy of an integrated intervention for PTSD symptoms and hazardous alcohol use developed for and delivered in primary care. Outcome data and session-by-session content for two participants are included, along with discussion of barriers encountered during the course of treatment. Clinician-suggested strategies for navigating barriers to facilitate utilization of integrated interventions for PTSD symptoms and hazardous alcohol use are also discussed.

Coping Flexibility and Alcohol-Related Outcomes: Examining Coping Motives as Mediators.

Background: Coping has been implicated in the etiology and treatment of problem drinking. Traditional, static measurement of coping styles (e.g., approach, avoidance, social support) may fail to capture how adaptive a given coping style may be. Coping flexibility is an emerging construct, associated with psychological health, and one that may shed light on coping's role in drinking risk. Coping flexibility includes (1) discontinuation of an ineffective coping strategy ("Discontinuation") and (2) production of an alternative strategy ("Implementation"). This study is the first to our knowledge to examine its association to drinking outcomes. Further, because coping deficits are theorized to lead to drinking through coping motives, we also examined mediated pathways from coping flexibility to alcohol outcomes via coping motives. Methods: College students (N = 528) completed an online assessment. Data were analyzed using path analysis. Control variables included sex and coping styles. Results: In path analytic models, Implementation was negatively associated with alcohol use and, indirectly via coping motives, negatively associated with alcohol consequences. The direct effect on alcohol use remained when controlling for coping styles and sex, but the mediational pathway was no longer significant. Conclusions: This study provides some evidence for the protective role of coping flexibility in alcohol use behavior, which may have implications for how best to address coping skills in alcohol interventions. The direct effect of Implementation on drinking suggests that there may be utility in teaching clients a flexible approach to coping in treatment. Replication, particularly with longitudinal designs, is needed.

Cognitive test batteries in animal cognition research: evaluating the past, present and future of comparative psychometrics.

For the past two decades, behavioural ecologists have documented consistent individual differences in behavioural traits within species and found evidence for animal "personality". It is only relatively recently, however, that increasing numbers of researchers have begun to investigate individual differences in cognitive ability within species. It has been suggested that cognitive test batteries may provide an ideal tool for this growing research endeavour. In fact, cognitive test batteries have now been used to examine the causes, consequences and underlying structure of cognitive performance within and between many species. In this review, we document the existing attempts to develop cognitive test batteries for non-human animals and review the claims that these studies have made in terms of the structure and evolution of cognition. We argue that our current test battery methods could be improved on multiple fronts, from the design of tasks, to the domains targeted and the species tested. Refining and optimising test battery design will provide many benefits. In future, we envisage that well-designed cognitive test batteries may provide answers to a range of exciting questions, including giving us greater insight into the evolution and structure of cognition.

The evolution of self-control.

Cognition presents evolutionary research with one of its greatest challenges. Cognitive evolution has been explained at the proximate level by shifts in absolute and relative brain volume and at the ultimate level by differences in social and dietary complexity. However, no study has integrated the experimental and phylogenetic approach at the scale required to rigorously test these explanations. Instead, previous research has largely relied on various measures of brain size as proxies for cognitive abilities. We experimentally evaluated these major evolutionary explanations by quantitatively comparing the cognitive performance of 567 individuals representing 36 species on two problem-solving tasks measuring self-control. Phylogenetic analysis revealed that absolute brain volume best predicted performance across species and accounted for considerably more variance than brain volume controlling for body mass. This result corroborates recent advances in evolutionary neurobiology and illustrates the cognitive consequences of cortical reorganization through increases in brain volume. Within primates, dietary breadth but not social group size was a strong predictor of species differences in self-control. Our results implicate robust evolutionary relationships between dietary breadth, absolute brain volume, and self-control. These findings provide a significant first step toward quantifying the primate cognitive phenome and explaining the process of cognitive evolution.

Can you teach an old parrot new tricks? Cognitive development in wild kaka (Nestor meridionalis).

Despite recent efforts to characterize innovative individuals within a species, we still know very little about the ontogeny of innovation ability. A number of studies have found that innovation rates are correlated with personality traits, such as neophilia and exploration. Juvenile birds are frequently more neophilic and explorative, yet few studies have found evidence of age-related differences in innovative problem-solving success. Here, we show consistently higher innovation efficiency in juveniles of a wild, omnivorous parrot species across a variety of tasks and contexts. We tested 104 kaka (Nestor meridionalis), ranging in age from four months to 13 years. Twenty-four individuals participated in all three of our problem-solving tasks, two of which involved a familiar feeder and one an entirely novel apparatus. Juveniles were the most efficient problem-solvers in all three tasks. By contrast, the adults' success was context dependent and limited to the novel apparatus, which did not require modification of a pre-learned behavioural response. This suggests greater behavioural flexibility in the juvenile birds, who also showed higher persistence and exploratory diversity than adults. These traits may enable young kaka to discover efficient foraging techniques, which are then maintained throughout adulthood.

Evidence suggesting that desire-state attribution may govern food sharing in Eurasian jays.

State-attribution is the ability to ascribe to others an internal life like one's own and to understand that internal, psychological states such as desire, hope, belief, and knowledge underlie others' actions. Despite extensive research, comparative studies struggle to adequately integrate key factors of state-attribution that have been identified by evolutionary and developmental psychology as well as research on empathy. Here, we develop a behavioral paradigm to address these issues and investigate whether male Eurasian jays respond to the changing desire-state of their female partners when sharing food. We demonstrate that males feed their mates flexibly according to the female's current food preference. Critically, we show that the males need to see what the female has previously eaten to know what food she will currently want. Consequently, the males' sharing pattern was not simply a response to their mate's behavior indicating her preference as to what he should share, nor was it a response to the males' own desire-state. Our results raise the possibility that these birds may be capable of ascribing desire to their mates.

Pilfering Eurasian jays use visual and acoustic information to locate caches.

Pilfering corvids use observational spatial memory to accurately locate caches that they have seen another individual make. Accordingly, many corvid cache-protection strategies limit the transfer of visual information to potential thieves. Eurasian jays (Garrulus glandarius) employ strategies that reduce the amount of visual and auditory information that is available to competitors. Here, we test whether or not the jays recall and use both visual and auditory information when pilfering other birds' caches. When jays had no visual or acoustic information about cache locations, the proportion of available caches that they found did not differ from the proportion expected if jays were searching at random. By contrast, after observing and listening to a conspecific caching in gravel or sand, jays located a greater proportion of caches, searched more frequently in the correct substrate type and searched in fewer empty locations to find the first cache than expected. After only listening to caching in gravel and sand, jays also found a larger proportion of caches and searched in the substrate type where they had heard caching take place more frequently than expected. These experiments demonstrate that Eurasian jays possess observational spatial memory and indicate that pilfering jays may gain information about cache location merely by listening to caching. This is the first evidence that a corvid may use recalled acoustic information to locate and pilfer caches.

Can male Eurasian jays disengage from their own current desire to feed the female what she wants?

Humans' predictions of another person's behaviour are regularly influenced by what they themselves might know or want. In a previous study, we found that male Eurasian jays (Garrulus glandarius) could cater for their female partner's current desire when sharing food with her. Here, we tested the extent to which the males' decisions are influenced by their own current desire. When the males' and female's desires matched, males correctly shared the food that was desired by both. When the female's desire differed from their own, the males' decisions were not entirely driven by their own desires, suggesting that males also took the female's desire into account. Thus, the male jays' decisions about their mates' desires are partially biased by their own desire and might be based upon similar processes as those found in humans.

Clinical feasibility of exercise-based A-V interval optimization for cardiac resynchronization: a pilot study.

BACKGROUND: One-third of eligible patients fail to respond to cardiac resynchronization therapy (CRT). Current methods to "optimize" the atrio-ventricular (A-V) interval are performed at rest, which may limit its efficacy during daily activities. We hypothesized that low-intensity cardiopulmonary exercise testing (CPX) could identify the most favorable physiologic combination of specific gas exchange parameters reflecting pulmonary blood flow or cardiac output, stroke volume, and left atrial pressure to guide determination of the optimal A-V interval. METHODS: We assessed relative feasibility of determining the optimal A-V interval by three methods in 17 patients who underwent optimization of CRT: (1) resting echocardiographic optimization (the Ritter method), (2) resting electrical optimization (intrinsic A-V interval and QRS duration), and (3) during low-intensity, steady-state CPX. Five sequential, incremental A-V intervals were programmed in each method. Assessment of cardiopulmonary stability and potential influence on the CPX-based method were assessed. RESULTS: CPX and determination of a physiological optimal A-V interval was successfully completed in 94.1% of patients, slightly higher than the resting echo-based approach (88.2%). There was a wide variation in the optimal A-V delay determined by each method. There was no observed cardiopulmonary instability or impact of the implant procedure that affected determination of the CPX-based optimized A-V interval. CONCLUSIONS: Determining optimized A-V intervals by CPX is feasible. Proposed mechanisms explaining this finding and long-term impact require further study.

College Women's Perceptions of a Friend-Based Intervention to Prevent Alcohol-Involved Sexual Assault.

Sexual assault (SA), particularly alcohol-involved SA, remains prevalent among college women. Because SA often begins in social contexts, bystander intervention has become a popular approach to prevention. Bystander interventions train individuals to intervene on behalf of others, including strangers, despite research indicating that intervention is more likely to occur when the bystander has a relationship with the target. Shifting the focus to friends as potential bystanders capitalizes on the qualities of relationship and responsibility that facilitate intervention. College women (N = 35) participated in focus groups (N = 8) during which they viewed a video prototype of a friend-based motivational interviewing (FMI) intervention session conducted with a friend dyad and provided feedback about the relevance and feasibility of using such an approach to reduce SA among friends who drink together in social settings. Content analysis of focus group transcripts yielded three themes: a) Friends as Natural Bystanders; b) The Role of Alcohol in Intervention, and c) Receptivity to FMI intervention. Women indicated that they feel responsible for keeping their friends safe, and that this sense of responsibility facilitates helping behaviors. Women also described ways through which alcohol intoxication can affect helping behavior. Women expressed enthusiasm for the FMI intervention approach and identified its emphasis on friendship and flexible approaches to personal safety as strengths. Findings highlight the promise of FMI intervention approaches that capitalize on the strengths of women's friendship to create safety goals that align with participants' values and overcome barriers to intervention, including alcohol intoxication.

The Hippo pathway regulates intestinal stem cell proliferation during Drosophila adult midgut regeneration.

Intestinal stem cells (ISCs) in the adult Drosophila midgut proliferate to self-renew and to produce differentiating daughter cells that replace those lost as part of normal gut function. Intestinal stress induces the activation of Upd/Jak/Stat signalling, which promotes intestinal regeneration by inducing rapid stem cell proliferation. We have investigated the role of the Hippo (Hpo) pathway in the Drosophila intestine (midgut). Hpo pathway inactivation in either the ISCs or the differentiated enterocytes induces a phenotype similar to that observed under stress situations, including increased stem cell proliferation and expression of Jak/Stat pathway ligands. Hpo pathway targets are induced by stresses such as bacterial infection, suggesting that the Hpo pathway functions as a sensor of cellular stress in the differentiated cells of the midgut. In addition, Yki, the pro-growth transcription factor target of the Hpo pathway, is required in ISCs to drive the proliferative response to stress. Our results suggest that the Hpo pathway is a mediator of the regenerative response in the Drosophila midgut.

Careful cachers and prying pilferers: Eurasian jays (Garrulus glandarius) limit auditory information available to competitors.

Food-storing corvids use many cache-protection and pilfering strategies. We tested whether Eurasian jays (Garrulus glandarius) reduce the transfer of auditory information to a competitor when caching and pilfering. We gave jays a noisy and a quiet substrate to cache in. Compared with when alone, birds cached less in the noisy substrate when with a conspecific that could hear but could not see them caching. By contrast, jays did not change the amount cached in the noisy substrate when they were with a competitor that could see and hear them caching compared with when they were alone. Together, these results suggest that jays reduce auditory information during caching as a cache-protection strategy. By contrast, as pilferers, jays did not attempt to conceal their presence from a cacher and did not prefer a silent viewing perch over a noisy one when observing caching. However, birds vocalized less when watching caching compared with when they were alone, when they were watching a non-caching conspecific or when they were watching their own caches being pilfered. Pilfering jays may therefore attempt to suppress some types of auditory information. Our results raise the possibility that jays both understand and can attribute auditory perception to another individual.

Repeatability and heritability of inhibitory control performance in wild toutouwai (Petroica longipes).

Despite increasing interest in the evolution of inhibitory control, few studies have examined the validity of widespread testing paradigms, the long-term repeatability and the heritability of this cognitive ability in the wild. We investigated these aspects in the inhibitory control performance of wild toutouwai (North Island robin; Petroica longipes), using detour and reversal learning tasks. We assessed convergent validity by testing whether individual performance correlated across detour and reversal learning tasks. We then further evaluated task validity by examining whether individual performance was confounded by non-cognitive factors. We tested a subset of subjects twice in each task to estimate the repeatability of performance across a 1-year period. Finally, we used a population pedigree to estimate the heritability of task performance. Individual performance was unrelated across detour and reversal learning tasks, indicating that these measured different cognitive abilities. Task performance was not influenced by body condition, boldness or prior experience, and showed moderate between-year repeatability. Yet despite this individual consistency, we found no evidence that task performance was heritable. Our findings suggest that detour and reversal learning tasks measure consistent individual differences in distinct forms of inhibitory control in toutouwai, but this variation may be environmentally determined rather than genetic.

The role of effortful control in mitigating negative consequences associated with emerging adult drinking.

BACKGROUND: Identifying factors that protect against alcohol-related negative consequences associated with emerging adult drinking is a critical public health issue. It has been proposed that high levels of self-regulation moderate risks associated with drinking, decreasing alcohol-related negative consequences. Past research testing this possibility is limited by a lack of advanced methodology for testing moderation and failure to consider facets of self-regulation. This study addressed these limitations. METHODS: Three hundred fifty-four community emerging adults (56% female; predominantly non-Hispanic Caucasian (83%) or African American (9%)) were assessed annually for 3 years. Moderational hypotheses were tested using multilevel models and the Johnson-Neyman technique was used to examine simple slopes. Data were organized such that repeated measures (level 1) were nested within participants (level 2) to test cross-sectional associations. Self-regulation was operationalized as effortful control and its facets (attentional, inhibitory, and activation control). RESULTS: We found evidence of moderation. The association between alcohol use during a heavy drinking week and consequences weakened as effortful control increased. This pattern was supported for two facets (attentional and activation control), but not for inhibitory control. Regions of significance results revealed that this protective effect was only evident at very high levels of self-regulation. CONCLUSIONS: The results provide some evidence that very high levels of attentional and activation control protect against alcohol-related negative consequences associated with drinking. Emerging adults who are very high in attentional and activation control are likely better able to control their attention and engage in goal-directed behavior, like leaving a party at a reasonable hour, or attending school and/or work when experiencing the punishing effects of a hangover. Results emphasize the importance of distinguishing facets of self-regulation when testing self-regulation models.

Effectiveness of Sexual Assault Protective Behaviors on the Daily Level: The Roles of Intoxication and Executive Control.

Young adult women engage in a variety of behaviors aimed at reducing their risk of sexual assault (SA), termed sexual assault protective behavioral strategies (SA-PBS), yet the evidence demonstrating the effectiveness of SA-PBS in reducing SA risk has been relatively sparse and inconclusive. The current study examined the use of SA-PBS, the factor structure of a diverse array of SA-PBS, and their association with the occurrence of SA. The influence of state- and trait-level moderators on the association between SA-PBS and SA events was also examined. In a sample of community young adult women (N = 174), use of SA-PBS and the occurrence of same night SA were examined with a longitudinal burst design over 1 year that spanned 27 weekend nights when women were out in social contexts. We also examined the influence of state intoxication of alcohol use and trait effortful control (EC) on the relationship between SA-PBS factors and SA events. We found that SA-PBS cluster into two factors representing Proactive and Reactive SA-PBS. While Proactive PBS was not associated with SA, Reactive PBS were positively associated with a SA event occurring. There was no evidence in the current sample to support a moderating role of intoxication on the relationship between Proactive or Reactive PBS and SA. However, there was a marginal interaction effect found for the moderating role of EC on the relationship between Proactive PBS and SA. Our findings identify important differences in SA-PBS, and perhaps most importantly, suggest that not all strategies are created equal with respect to reducing risk.

Social Goal Orientation Differentially Influences Exposure to Interpersonal and Noninterpersonal Trauma.

Emerging adults are at an increased risk for trauma exposure, both interpersonal and non-interpersonal, which often occurs within a social context. How an individual interacts with this context may heighten or buffer against their risk for trauma. Social goal orientation represents individual differences that characterize how an individual navigates their social environment. These orientations fall along the two interacting dimensions, Agency and Communion. In a community sample (N=274; 55% female, average age = 18.9) of young adults, we sought to examine the role that these two types of social goals, both uniquely and in interaction with one another, may play in interpersonal and non-interpersonal trauma risk. Because men and women are at differential risk for trauma, we also examined the impact of gender on these associations. Findings revealed that social goal orientations are linked to trauma exposure in ways that differ depending on the type of trauma, interpersonal or non-interpersonal. Moreover, these processes differed for men and women. Whereas a high Communal Orientation was associated with decreased exposure to all trauma, for both women and men, Agentic Orientation was associated with an increased number of interpersonal and non-interpersonal trauma. For men, agency and communion interacted, suggesting that the extent to which an agentic orientation may be risky or protective for interpersonal trauma depends strongly on communal orientation. These findings provided initial evidence for the role social goal orientation may play as a risk or protective factor for trauma exposure.

Animal tool use: Many tools make light work for wild parrots.

Tool set use is rare in the animal kingdom. Previously, only primates were known to use multiple tools with different functions to achieve a single goal. New research now reveals the convergent evolution of tool set use in wild parrots.

The differential effects of verbal sexual coercion and forcible sexual assault on alcohol use and consequence trajectories in the first year of college.

OBJECTIVE: Verbal sexual coercion (VSC) is the most prevalent and pervasive form of sexual victimization that women experience, yet the long-term harmful effects of this type of experience are unknown. The current study examined the effects of verbal sexual coercion versus forcible sexual assault (FSA) on alcohol use and alcohol consequences, two deleterious outcomes that have been linked to sexual victimization. METHOD: In a sample of college women (N = 649), lifetime history of VSC and FSA were examined as predictors of trajectories of alcohol outcomes with latent growth models. Participants were assessed at six timepoints over their first year of college, a critical transition period of increased risk for both alcohol use and trauma exposure. We also examined the influence of victimization characteristics, such as relationship to the perpetrator and revictimization experiences in these associations. RESULTS: VSC experiences were predictive of higher levels of alcohol use and alcohol-related consequences (i.e., intercept). This risk was sustained throughout the first year of college. VSC experiences did not predict changes (i.e., slope) in alcohol outcomes over this time. In contrast, FSA was not predictive of either initial level or change in alcohol use and consequences over time. CONCLUSION: Findings highlight the importance of distinguishing among types of coercive experiences, as they show unique associations with later harmful outcomes. Verbal sexual coercion, common in the lives of young women but often overlooked in the extant literature, is associated with substantial negative impact during the first year of college.

Memory Performance Influences Male Reproductive Success in a Wild Bird.

Despite decades of comparative research, how selection shapes the evolution of cognitive traits remains poorly understood [1-3]. Several lines of evidence suggest that natural selection acts on spatial memory in food-caching species [3-6]. However, a link between reproductive fitness and spatial memory ability has yet to be demonstrated in any caching species [1, 3, 6]. Here, we show that memory performance influences reproductive success differentially for males and females in a caching songbird, the New Zealand robin (Petroica longipes). Males' memory performance in a spatial task during winter influenced their subsequent breeding success; individuals with more accurate performance produced more fledglings and independent offspring per nesting attempt. Males with superior memory performance also provided an increased proportion of large prey items to chicks in the nest and spent less time flying while foraging and provisioning. No such effects were found for females. Previous research reveals that trade-offs may constrain selection and act to maintain variation in cognitive traits [7]. The gender dimorphism in the reproductive benefits of robin memory performance suggests an additional role for divergent selection between the sexes in constraining runaway selection on male memory ability [8], ultimately maintaining variation in this cognitive trait.
