Across species and ages, planning multi-step actions is a hallmark of intelligence and critical for survival. Traditionally, researchers adopt a "top-down" approach to action planning by focusing on the ability to create an internal representation of the world that guides the next step in a multi-step action. However, a top-down approach does not inform on underlying mechanisms, so researchers can only speculate about how and why improvements in planning occur. The current study takes a "bottom-up" approach by testing developmental changes in the real-time, moment-to-moment interplay among perceptual, neural, and motor components of action planning using simultaneous video, motion-tracking, head-mounted eye tracking, and electroencephalography (EEG). Preschoolers (n = 32) and adults (n = 22) grasped a hammer with their dominant hand to pound a peg when the hammer handle pointed in different directions. When the handle pointed toward their non-dominant hand, younger children ("nonadaptive planners") used a habitual overhand grip that interfered with wielding the hammer, whereas adults and older children ("adaptive planners") used an adaptive underhand grip. Adaptive and nonadaptive children differed in when and where they directed their gaze to obtain visual information, neural activation of the motor system before reaching, and straightness of their reach trajectories. Nonadaptive children immediately used a habitual overhand grip before gathering visual information, leaving insufficient time to form a plan before acting. Our novel bottom-up approach transcends mere speculation by providing converging evidence that the development of action planning depends on a real-time "tug of war" between habits and information gathering and processing.

Fetal, infant, and toddler neuroimaging is commonly thought of as a development of modern times (last two decades). Yet, this field mobilized shortly after the discovery and implementation of MRI technology. Here, we provide a review of the parallel advancements in the fields of fetal, infant, and toddler neuroimaging, noting the shifts from clinical to research use, and the ongoing challenges in this fast-growing field. We chronicle the pioneering science of fetal, infant, and toddler neuroimaging, highlighting the early studies that set the stage for modern advances in imaging during this developmental period, and the large-scale multi-site efforts which ultimately led to the explosion of interest in the field today. Lastly, we consider the growing pains of the community and the need for an academic society that bridges expertise in developmental neuroscience, clinical science, as well as computational and biomedical engineering, to ensure special consideration of the vulnerable mother-offspring dyad (especially during pregnancy), data quality, and image processing tools that are created, rather than adapted, for the young brain.

The objective of this article is to examine the experiences and challenges faced by Black professionals in the academic psychiatry workforce. The authors used data collected from previous literature to explore experiences faced at each level of the academic psychiatry pipeline. Review of the literature revealed that systemic barriers contribute to burnout, high turnover, and underrepresentation of Black professionals in academic psychiatry. Retention of Black mental health professionals is fostered by institutional support and interventions that address racism and promote growth and development at every level. While there appears to be a growing body of literature in social medical and popular press, peer-reviewed literature on the experiences of Black trainees and professionals in academic psychiatry is still limited. Additional studies, including systematic data collection among Black psychiatrists, psychologists, faculty, and clinical support staff in academic settings, are needed to continue to examine experiences related to race and racism along the educational and professional workforce continuum.

BACKGROUND:Intergenerational transmission of abuse processes imply that individuals abused as children are more likely to abuse their own children when they become parents, with similar intergenerational patterns observed for parenting styles. OBJECTIVE:The present study addresses an important gap in the literature regarding the intergenerational cycle, investigating how perceived parenting style history predicts mothers' and fathers' child abuse risk across the transition to parenthood, with particular attention to the role of gender by comparing cross-gender and same-gender grandparent-parent dyads. PARTICIPANTS AND METHODS:The sample is drawn from a four-wave longitudinal study that enrolled 203 families beginning the final trimester of mothers' pregnancy until children were four years old. Parents responded to measures on parenting style history received from both their mothers and fathers as well as measures of their own child abuse risk, parent-child aggression, and personal parenting style. RESULTS:Mothers demonstrated more same-gender effects, whereas fathers demonstrated more cross-gender effects-both patterns supportive of a tendency to follow maternal influences when considering child abuse risk. With regards to behavior, both mothers' and fathers' reports of parent-children aggression were most influenced by perceived harsh parenting received from their fathers. CONCLUSIONS:Future development of parenting interventions could be more individualized to the participating parent's reported personal history of parenting style and gender.

Although intimate partner violence (IPV) is often conceptualized as occurring unilaterally, reciprocal or bidirectional violence is actually the most prevalent form of IPV. The current study assessed physical IPV experiences in couples and evaluated risk and protective factors that may be differentially associated with reciprocal and nonreciprocal IPV concurrently and over time. As part of a multi-wave longitudinal study, women and men reported on the frequency of their IPV perpetration and victimization three times across the transition to parenthood. Participants also reported on risk factors related to personal adjustment, psychosocial resources, attitudes toward gender role egalitarianism, and sociodemographic characteristics at each wave. Participants were classified into one of four IPV groups (reciprocal violence, male perpetrators only, female perpetrators only, and no violence) based on their self-report and based on a combined report, which incorporated both partners' reports of IPV for a maximum estimate of violence. Women and men were analyzed separately, as both can be perpetrators and/or victims of IPV. Cross-sectional analyses using self-reported IPV data indicated that IPV groups were most consistently distinguished by their levels of couple satisfaction, across gender; psychological distress also appeared to differentiate IPV groups, although somewhat less consistently. When combined reports of IPV were used, sociodemographic risk markers (i.e., age, income, and education) in addition to couple functioning were among the most robust factors differentiating IPV groups concurrently, across gender. In longitudinal analyses, sociodemographic vulnerabilities were again among the most consistent factors differentiating subsequent IPV groups over time. Several gender differences were also found, suggesting that different risk factors (e.g., women's social support and men's emotion regulation abilities) may need to be targeted in interventions to identify, prevent, and treat IPV among women and men.

Despite major anatomical differences with other mammalian sensory systems, olfaction shares with those systems a modulation by sleep/wake states. Sleep modulates odor sensitivity and serves as an important regulator of both perceptual and associative odor memory. In addition, however, olfaction also has an important modulatory impact on sleep. Odors can affect the latency to sleep onset, as well as the quality and duration of sleep. Olfactory modulation of sleep may be mediated by direct synaptic interaction between the olfactory system and sleep control nuclei, and/or indirectly through odor modulation of arousal and respiration. This reciprocal interaction between sleep and olfaction presents novel opportunities for sleep related modulation of memory and perception, as well as development of non-pharmacological olfactory treatments of simple sleep disorders.
