Crying in infancy is an important emotional signal that elicits care from adults, and women are often assumed to be more sensitive and reactive to infant crying than men. In a series of studies, we tested whether preparenthood gender differences in sensitivity to infant cries are a potential driver of the unequal share of early parenting. In Study 1, we tested for differences in men and women's awakening to infant crying and alarms among nonparents in an overnight experiment (N = 142). We found that at the lowest sound volumes only, estimated at a sound pressure level of between 33 and 44 decibels, women were 14% more likely to wake than men to both infant crying and alarm sounds. There were no differences between women and men at louder sound volumes. In Study 2, we examined the nighttime caregiving patterns of first-time parents over a week using experience sampling to obtain reports from both fathers and mothers (N = 117). We found that mothers were, on average, three times more likely to check on or respond to their infants at night than fathers. In 23% of couples, there was some evidence for equal sharing. Finally, in a simulation study, we reconstructed the distribution of care that could emerge from the awakening differences observed in Study 1. We then compared these simulations to the empirical nighttime caregiving patterns reported by first-time parents in Study 2. Our simulation showed that the large difference between parents' nighttime caregiving was unlikely to emerge from the small preparenthood differences in awakening likelihood. We conclude that the greater maternal share of nighttime caregiving cannot plausibly be explained by inherent preparenthood differences in auditory reactivity or nocturnal waking behavior in men or women.

Decisions are not necessarily easy to separate into a planning and an execution phase and the decision-making process can often be reflected in the movement associated with the decision. Here, we used formalized definitions of concepts relevant in decision-making and learning to explore if and how these concepts correlate with decision-related movement paths, both during and after a choice is made. To this end, we let 120 participants (46 males, mean age = 24.5 years) undergo a repeated probabilistic two-choice task with changing probabilities where we used mouse-tracking, a simple non-invasive technique, to study the movements related to decisions. The decisions of the participants were modelled using Bayesian inference which enabled the computation of variables related to decision-making and learning. Analyses of the movement during the decision showed effects of relevant decision variables, such as confidence, on aspects related to, for instance, timing and pausing, range of movement and deviation from the shortest distance. For the movements after a decision there were some effects of relevant learning variables, mainly related to timing and speed. We believe our findings can be of interest for researchers within several fields, spanning from social learning to experimental methods and human–machine/robot interaction.

Inequality affects how people make social decisions. Laboratory research has shown that when income inequality is simulated using cooperative economic games, groups with higher inequality often generate less wealth overall, with poorer group members receiving the worst outcomes. This study links these experimental findings to real world inequality and applies a decision model to explain the effects in terms of social decision-making dynamics. Using a pre-existing dataset from 255 groups playing a public goods game in thirteen economically diverse societies, we show that in nations with higher inequality, groups contribute less (Research question (RQ) 1). Further, we find that higher inequality is associated with lower optimism regarding others’ contributions at the outset of the game and increased sensitivity to others’ contributions, which accelerates the decay of cooperation (RQ2). These effects might be explained by national differences in social capital as expressed by trust and adherence to civic norms (RQ3). Using the European Values Survey, we replicate the negative association between inequality and contributions to a public good by examining national volunteering rates (RQ4).

Is inner speech involved in sustaining attention, and is this reflected in response times for stimulus detection? In Experiment 1, we measured response times to an infrequently occurring stimulus (a black dot appearing at 1-3 min intervals) and subsequently asked participants to report on the character of their inner experience at the time the stimulus appeared. Our main preregistered hypothesis was that there would be an interaction between inner speech and task relevance of thought with reaction times being the fastest on prompts preceded by task-relevant inner speech. This would indicate that participants could use their inner voice to maintain performance on the task. With generalized linear mixed-effects models fitted to a gamma distribution, we found significant effects of task relevance but no interaction with inner speech. However, using a hierarchical Bayesian analysis method, we found that trials preceded by task-relevant inner speech additionally displayed lower standard deviation and lower mode (independently of the main effect of task relevance), suggestive of increased processing efficiency. Due to deviations from the preregistered sampling and analysis procedures, we replicated our findings in Experiment 2. Our results add support to the hypothesis that inner speech serves a functional role in top-down attentional control. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

While infant fearfulness, and its expression via crying, may have been adaptive in our evolutionary history, for modern parents, crying can be challenging to respond to. We discuss how and why prolonged crying can raise the risk for difficulties with adult care. Given that crying is the most-reported trigger for shaking, its potential to elicit maladaptive responses should not be overlooked.

AbstractCrying is an ubiquitous communicative signal in infancy. This meta‐analysis synthesizes data on parent‐reported infant cry durations from 17 countries and 57 studies until infant age 12 months (N = 7580, 54% female from k = 44; majority White samples, where reported, k = 18), from studies before the end Sept. 2020. Most studies were conducted in the United States, the United Kingdom, and Canada (k = 32), and at the traditional cry “peak” (age 5–6 weeks), where the pooled estimate for cry and fuss duration was 126 mins (SD = 61), with high heterogeneity. Formal modeling of the meta‐analytic data suggests that the duration of crying remains substantial in the first year of life, after an initial decline.

This brief note points toward new potentials that lie at the interface between research on landscape archaeology and cognitive science. Recent advances in the cognitive and neural sciences have sharpened our understanding of spatial cognition, by providing new explanations for how the brain reduces the dimensionality of complex topography and geography for effective navigation. This research suggests that space is represented in grid-like structures in the brain, and that grid-like forms are a basic ingredient of spatial processing. At the same time, recent archaeological research shows that the organization of larger-scale space into linear forms, and in particular grid-like landscapes, is a relatively recent social invention, which suggests that these forms are historically and culturally contingent. Taken together, this research raises the question of how the dimensionality-reducing function of grid-like processing in the brain is related to higher-level conceptual and imaginative processing of space needed to plan and negotiate large-scale landscape structures. This brief note motivates this question and argues for further exploration of the relationships between biological, cognitive, and cultural processes related to space and its conceptualization between these fields of research.

Perceptual decision-making employs a range of higher order metacognitive processes. Two of the most important of these are perceptual awareness; or the clarity with which one reports seeing a perceptual stimulus, and response confidence; or the certainty one has about the correctness of one's own perceptual categorizations. We used a novel false feedback paradigm to investigate the relationships between these two processes. We asked people to perform a standard psychophysical detection task. We used feedback to selectively intervene either on our participants’ trust in their own perceptual awareness of the stimulus, or on their confidence in their own responses. We measured the effects of these interventions on response accuracy; on reports of perceptual awareness; and on response confidence. We found that by undermining people's trust in their awareness of the sensory stimulus, we could reliably reduce their accuracy on the task. We suggest that the reason this occurred is that people came to rely less on evidence from their senses when making perceptual decisions. We conclude by suggesting that there is a not a one-to-one mapping between content in conscious experience and how that content is used in perceptual decision making, and that one's perception of the reliability of content also plays a role.

We explore the relationship between academic employees' attitudes to modern sexism and the #MeToo movement to better understand how interventions designed to address sexual harassment might be received in Danish academia. Using a survey of employees at a large Danish university (N = 1128), we categorized employees' open answers about their attitudes to the #MeToo Movement as (a) positive, (b) ambivalent, or (c) negative. These categories were associated with employees' modern sexism scores, such that those higher in modern sexism were more likely to be negative about the movement, while those with lower scores were more likely to be positive. To better understand possible sources of resistance to policy interventions, we used an explanatory sequential mixed-methods design to analyse the open comments for themes related to employee's negative attitudes towards #MeToo. The two most prominent themes were: (1) delegitimisation of the purposes of the movement, and (2) perception that the rights of potential sexual perpetrators were more important than those of potential victims. We discuss the implications for the implementation of interventions targeting sexual harassment.

Autism spectrum disorder (ASD) - and autistic traits more generally - are associated with a heterogeneous pattern of differences in cognitive function. These include differences in associative learning, attention, and processing of social information. All three cognitive functions have importance in clinical, educational, and research contexts. The present study investigates the relationships between these functions in the context of autistic traits in the neurotypical population. In an online study, we asked a group of over 400 people to complete the Autism Spectrum Quotient questionnaire. We also asked participants to complete one of two standard attentional learning paradigms - either a Kamin blocking or an attentional highlighting task. To investigate the relation of attention and learning to social information processing, we incorporated social cues in one of each kind of paradigm. We found Kamin blocking increased with increasing number of autistic traits, in particular the sub-trait attention switching, but only for non-social cues. We found that highlighting decreased with increasing number of traits, in particular the sub trait communication, but only for social cues. We interpret these findings as evidence of a crucial role for attention in other characteristics of the broader autistic phenotype, and discuss the relevance of these results for cognitive explanations of autistic traits and symptoms.

The authors of this letter represent a large student body who have generally had especially positive experiences with female mentors’ advice and mentorships and do not support the conclusions of the article “The association between early career informal mentorship in academic collaborations and junior author performance” because its conclusions regarding gender reach beyond the article’s scope and because the quality of mentorships cannot be analysed only through citation counts. Publications are not equivalent to learning outcomes or professional advancement.After careful review of the aforementioned article, we see numerous scientific flaws. The causal inferences that can be drawn from the observed effects of gender on the mentor-protégé relationship are insubstantial and other aspects of the paper are limited in the reductionist design of their mentor-protégé relationship assessment, which is based on the scientific impact of future papers.

Problem gambling has been linked to impairments in decision-making under uncertainty. Problem gamblers are more likely to favor high-risk, high-reward, and short-term gains over more advantageous choice alternatives, and this preference has been linked to impaired learning about decision outcomes. In this paper we link specific learning processes in decision-making to specific harms related to problem gambling. We asked a group of 140 casual gamblers to 1) perform a canonical decision-making task (the Iowa Gambling Task) online, and 2) to complete a self-report survey (the GamTest) designed to measure self-perceived harm caused by their gambling. We used a reinforcement learning model to explain individual differences in the decision task, and related individuals' model parameters to the specific problem areas reported using the questionnaire. We found that people who learned more from gains than from losses on the task were more likely to report overall gambling problems, and problems specifically related to money. We also found that people whose learning was more driven by the frequency of rewards were more likely to report problems related to the amount of time spent gambling, as well as social problems. We discuss possible psychological and neural processes mediating learning and gambling related harms, and we discuss the relevance of our approach to the diagnosis of problem gambling and its consequences.

Schizophrenia is often associated with distinctive or odd social behaviours. Previous work suggests this could be due to a general reduction in conformity; however, this work only assessed the tendency to publicly agree with others, which may involve a number of different mechanisms. In this study, we specifically investigated whether patients display a reduced tendency to adopt other people’s opinions (socially learned attitude change). We administered a computerized conformity task, assumed to rely on reinforcement learning circuits, to 32 patients with schizophrenia or schizo-affective disorder and 39 matched controls. Each participant rated 153 faces for trustworthiness. After each rating, they were immediately shown the opinion of a group. After approximately 1 hour, participants were unexpectedly asked to rate all the faces again. We compared the degree of attitude change towards group opinion in patients and controls. Patients presented equal or more social influence on attitudes than controls. This effect may have been medication induced, as increased conformity was seen with higher antipsychotic dose. The results suggest that there is not a general decline in conformity in medicated patients with schizophrenia and that previous findings of reduced conformity are likely related to mechanisms other than reinforcement based social influence on attitudes.

The field of social robotics offers an unprecedented opportunity to probe the process of impression formation and the effects of identity-based stereotypes (e.g. about gender or race) on social judgements and interactions. We present the concept of fair proxy communication-a form of robot-mediated communication that proceeds in the absence of potentially biasing identity cues-and describe how this application of social robotics may be used to illuminate implicit bias in social cognition and inform novel interventions to reduce bias. We discuss key questions and challenges for the use of robots in research on the social cognition of bias and offer some practical recommendations. We conclude by discussing boundary conditions of this new form of interaction and by raising some ethical concerns about the inclusion of social robots in psychological research and interventions. This article is part of the theme issue 'From social brains to social robots: applying neurocognitive insights to human-robot interaction'.

Multisensory processing facilitates perception of our everyday environment and becomes particularly important when sensory information is degraded or close to the discrimination threshold. Here, we used magnetoencephalography and an audiovisual oddball paradigm to assess the complementary role of visual information in subtle pitch discrimination at the neural level of participants with varying levels of pitch discrimination abilities, i.e., musicians and nonmusicians. The amplitude of the auditory mismatch negativity (MMNm) served as an index of sensitivity. The gain in amplitude resulting from compatible audiovisual information was larger in participants whose MMNm amplitude was smaller in the condition deviating only in the auditory dimension, in accordance with the multisensory principle of inverse effectiveness . These findings show that discrimination of even a sensory-specific feature as pitch is facilitated by multisensory information at a pre-attentive level, and they highlight the importance of considering inter-individual differences in uni-sensory abilities when assessing multisensory processing.

We designed this study to measure the degree of backlash a specific Danish university would encounter in response to gender equity interventions. To capture this resistance we used two standardized questionnaires: the Modern Sexism Scale, which measures explicit denial of gender discrimination and resentment towards gender equity demands (such as gender interventions) andthe Support for Discriminatory Practices which measures peoples explicit preferences for hiring men over women. We also asked an open question about attitudes towards the university’s current gender policies. The questionnaire was sent to 15,493 employees. With one prompt 1,805 completed the entire questionnaire. We found that university employees scored above the midpoint on modern sexism, indicating that, on average, they held sexist attitudes. We further showed that modern sexism scores varied depending on beliefs about what was being done forgender equity in the organization, such that those who thought that enough or too much was being done had significantly higher sexism scores than those who thought that not enough wasbeing done. Over all, our findings document explicit sexist attitudes within the target university and suggest that gender equity interventions are therefore likely to be met by great resistancefrom some.

Imitation plays a key role in social learning and in facilitating social interactions and likely constitutes a basic building block of social cognition that supports higher-level social abilities. Recent findings suggest that patients with schizophrenia have imitation impairments that could contribute to the social impairments associated with the disorder. However, extant studies have specifically assessed voluntary imitation or automatic imitation of emotional stimuli without controlling for potential confounders. The imitation impairments seen might therefore be secondary to other cognitive, motoric, or emotional deficits associated with the disorder. To overcome this issue, we used an automatic imitation paradigm with nonemotional stimuli to assess automatic imitation and the top-down modulation of imitation where participants were required to lift one of 2 fingers according to a number shown on the screen while observing the same or the other finger movement. In addition, we used a control task with a visual cue in place of a moving finger, to isolate the effect of observing finger movement from other visual cueing effects. Data from 33 patients (31 medicated) and 40 matched healthy controls were analyzed. Patients displayed enhanced imitation and intact top-down modulation of imitation. The enhanced imitation seen in patients may have been medication induced as larger effects were seen in patients receiving higher antipsychotic doses. In sum, we did not find an imitation impairment in schizophrenia. The results suggest that previous findings of impaired imitation in schizophrenia might have been due to other cognitive, motoric, and/or emotional deficits.

We introduce a new model of adaptive criterion setting within a signal detection framework, and show how this provides psychological insights that allow us to segregate causes of suboptimality in perceptual learning. We apply this to a perceptual learning task for both neurotypical and autistic participants. The model parameters provide a bridge between the mechanisms of an aberrant precision account of autism and resulting behavior that can be interpreted within a receiver operating characteristic framework. The model makes superior out-ofsample predictions compared to standard signal detection theory, about how people adapt to different environmental manipulations when asked to categorize audio-spatial stimuli. We find that accuracy of participants is more strongly correlated to the construct of persistence signals that inhibit response flexibility, than to the neuromodulatory gain. We also find evidence for individual differences in persistence that are correlated to scores on the autistic traits questionnaire.

Difficulties in emotion perception are commonly observed in autism spectrum disorder. However, it is unclear whether these difficulties can be attributed to a general problem of relating to emotional states, or whether they specifically concern the perception of others’ expressions. This study addressed this question in the context of pain, a sensory and emotional state with strong social relevance. We investigated pain evaluation in self and others in 16 male individuals with autism spectrum disorder and 16 age- and gender-matched individuals without autism spectrum disorder. Both groups had at least average intelligence and comparable levels of alexithymia and pain catastrophizing. We assessed pain reactivity by administering suprathreshold electrical pain stimulation at four intensity levels. Pain evaluation in others was investigated using dynamic facial expressions of shoulder patients experiencing pain at the same four intensity levels. Participants with autism spectrum disorder evaluated their own pain as being more intense than the pain of others, showing an underestimation bias for others’ pain at all intensity levels. Conversely, in the control group, self- and other evaluations of pain intensity were comparable and positively associated. Results indicate that emotion perception difficulties in autism spectrum disorder concern the evaluation of others’ emotional expressions, with no evidence for atypical experience of own emotional states.
