Parental care is a critical determinant of offspring fitness. Female presence and male competition affect paternal care, but male-male cooperation during mating may also be an important, yet underappreciated, driver of paternal care. In many systems, males work together to court females or defend territories against male competitors. This male-male cooperation can alter actual or perceived paternity of the parenting male and could, therefore, influence how males invest in care during the postmating period. Here, we measured how reproductive and social dynamics between nesting and satellite males during mating correlate with nesting male paternal care in the ocellated wrasse (Symphodus ocellatus). Although paternal care (fanning rates) was repeatable across days within the same nesting cycle, it was not repeatable across different nesting cycles, suggesting that males plastically alter care in response to the environment. Nesting males provided care for fewer days at nests with the most unstable relationship between the nesting and satellite male: nests with low satellite cooperation and high male-male conflict where the satellite eventually left or was evicted from the nest. Nesting males also parented more intensively, but for fewer days in the warmer year, suggesting that males may adjust care in response to temperature. Collectively, our results suggest that there is no fixed male trait that females can use to predict paternal care behavior. Instead, females may use male-male interactions as a proxy for the quality of care her offspring will receive, suggesting that sexual selection may favor the co-evolution of paternal care with male-male cooperation. © 2025 The Author(s).

This study examined whether embedding baselining within the Reality Interview (RI) protocol enhances intuitive veracity judgments. Baselining involves using a person’s truthful verbal behavior as a reference point for evaluating the veracity of subsequent statements. We hypothesized that access to a comparable truth baseline (CTB) would improve veracity judgment accuracy. Eyewitnesses of a mock crime were interviewed with the RI and instructed to respond either honestly or deceptively. Laypeople (Experiment 1) and police officers (Experiment 2) evaluated these statements with or without a CTB. With a CTB, laypeople showed significantly higher accuracy in detecting deception and a reduced truth bias. However, police officers showed no improvement, maintaining chance-level performance regardless of statement veracity. These findings suggest that CTBs enhance lie detection in laypeople but not in trained professionals. Future research should explore tailored approaches to improving veracity judgments, perhaps incorporating specific guidelines on how to best use available cues. © 2025 The Author(s).

Background: Stimulant use disorder (StUD) and attention-deficit/hyperactivity disorder (ADHD) frequently co-occur. This comorbidity complicates treatment and worsens clinical outcomes. Despite the high prevalence, shared vulnerability and clinical relevance of this comorbidity, evidence on effective pharmacotherapies among individuals with this dual diagnosis remains limited. Materials and methods: This systematic review protocol is reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) statement and will include randomized controlled trials involving adults with comorbid StUD (cocaine, amphetamines, or methamphetamines) and ADHD. The following databases will be searched: PubMed, Embase, Scopus, and Web of Science. Covidence will be used to support independent screening and data extraction. Two reviewers will independently screen studies (title/abstract and full text). One author will extract data, which will be independently verified by a second reviewer. Quality assessment of included articles will be assessed using the Cochrane Risk of Bias instrument, and certainty of the evidence for each outcome will be assessed using Grading of Recommendations, Assessment, Development and Evaluations (GRADE) methodology. Primary outcomes include duration of continuous abstinence, odds of stimulant-negative urine samples, ADHD symptom changes, and medication adverse events. Where feasible, meta-analyses will be conducted using random-effects models. Significance and dissemination: This review will synthesize existing evidence on the efficacy of pharmacotherapies (stimulants and non-stimulants) for individuals with co-occurring StUD and ADHD. The results of this study will likely inform clinical practice by evaluating outcomes such as reduction in stimulant use and abstinence, and improvement in ADHD symptoms. Findings will be disseminated through peer-reviewed publication and presentations to reach both clinical and academic audiences. Systematic review registration: PROSPERO, CRD420250655356.

PURPOSE: Autistic adults consistently report difficulties understanding speech in adverse listening environments, which may be related to differences in social communication and participation. Research examining masked-speech recognition in autistic adults is limited, particularly in competing speech backgrounds with high degrees of informational masking. This work characterizes speech-in-speech and speech-in-noise recognition in young adults on the autism spectrum, as well as evaluates self-reported functional listening abilities and listening-related fatigue. METHOD: Masked-speech recognition was evaluated in both autistic (n = 20) and non-autistic (n = 20) young adults with normal hearing. Speech reception thresholds were adaptively measured in two-talker speech and speech-shaped noise using target sentences that were either semantically meaningful or anomalous. Functional listening abilities and listening-related fatigue were assessed using the Speech, Spatial, and Qualities of Hearing Scale and the Vanderbilt Fatigue Scale for Adults. Autism characteristics and social communication experiences were quantified using the Social Responsiveness Scale-Second Edition. RESULTS: Autistic adults displayed significantly poorer speech-in-speech recognition than their non-autistic peers, while speech-in-noise recognition did not differ between groups. Functional listening difficulties in daily life and listening-related fatigue were significantly higher for autistic participants. Autism characteristics strongly predicted functional listening abilities and listening-related fatigue in both groups. CONCLUSIONS: Autistic young adults experience objective speech-in-speech recognition difficulties that correspond with listening challenges in daily life. Autism characteristics and social communication experiences predict functional listening abilities reported by both autistic and non-autistic young adults with normal hearing. Speech-in-speech recognition difficulties observed here may amplify social communication challenges for adults on the autism spectrum. Future work must prioritize improved awareness of autistic listening differences.

Stereotypes about aging and aging anxieties are common and when internalized are related to poor physical and psychological outcomes. As a result, older adults may view themselves as having their best years behind them. The present study investigates ageism and aging anxiety as barriers to positive self-development. Participants (n = 360) between ages of 19 and 77 years old (M = 39, SD = 15.9) were recruited using Amazon Mechanical Turk (MTurk) and completed measures of Ageism, Aging Anxiety, and were asked to identify when they have been or will be their Best Self. With increasing age, adults with more internalized ageism and more aging anxiety, specifically physical appearance and fear of loss, identified their Best Self with a time in the past. These findings support the idea that internalization of ageism and aging anxiety can be counterproductive for expectations for growth as one ages.
