Subliminal priming and persuasion: Striking while the iron is hot

Three studies demonstrated that subliminally priming a goal-relevant cognition (thirst in Studies 1 and 2; sadness in Study 3) influenced behavior (in Study 1) and enhanced the persuasiveness of an ad targeting the goal (in Studies 2 and 3) when people were motivated to pursue the goal (when they were thirsty in Studies 1 and 2; when they expected to interact with another person in Study 3). These results suggest that subliminal priming can be used to enhance persuasion, but only when certain conditions are met. Both the priming of goal-relevant cognitions and the motive to pursue the goal were necessary for ads targeting the goal to be more persuasive. The implications of these results for the role of functionality in subliminal priming and for the use and abuse of subliminal priming in persuasion are discussed.     

Waimānalo Pono Research Hui: A Community–Academic Partnership to Promote Native Hawaiian Wellness through Culturally Grounded and Community‐Driven Research and Programming

Although Hawai‘i is often portrayed as an idyllic paradise and is recognized as one of the healthiest States in the United States, pervasive health disparities exist among Native Hawaiians. Similar to other indigenous populations across the globe, these disparities are linked to unjust social and economic policies rooted in colonization and historical trauma. Western‐centric efforts to address these disparities have yielded limited results. Consequently, indigenous frameworks to decolonize western‐centric research processes have emerged. The Waimānalo Pono Research Hui is an example of a community–academic partnership that uses indigenous methodologies and principles of community‐based participatory research as the foundation to engage Native Hawaiian community members in research. Monthly gatherings are held where community members and academic researchers share a meal and discuss community priorities with the goal of shaping research and programming that are rooted in Native Hawaiian values. A mission for the group has been created as well as protocols for community engagement to ensure all projects that work with the Waimānalo Pono Research Hui are ethically sound and grounded in the community's preferences, cultural knowledge, and lived experiences. Our community members continually report that the Waimānalo Pono Research Hui has positively transformed their perception of and willingness to engage in research. Similarly, university students and academic researchers express how much their knowledge about working with communities has grown and inspired them. Creating spaces for communities and researchers to build authentic relationships and engage in ongoing conversations can promote culturally grounded and community‐driven research and programming.     

Early adversity in rural India impacts the brain networks underlying visual working memory

There is a growing need to understand the global impact of poverty on early brain and behavioural development, particularly with regard to key cognitive processes that emerge in early development. Although the impact of adversity on brain development can trap children in an intergenerational cycle of poverty, the massive potential for brain plasticity is also a source of hope: reliable, accessible, culturally agnostic methods to assess early brain development in low resource settings might be used to measure the impact of early adversity, identify infants for timely intervention and guide the development and monitor the effectiveness of early interventions. Visual working memory (VWM) is an early marker of cognitive capacity that has been assessed reliably in early infancy and is predictive of later academic achievement in Western countries. Here, we localized the functional brain networks that underlie VWM in early development in rural India using a portable neuroimaging system, and we assessed the impact of adversity on these brain networks. We recorded functional brain activity as young children aged 4–48 months performed a VWM task. Brain imaging results revealed localized activation in the frontal cortex, replicating findings from a Midwestern US sample. Critically, children from families with low maternal education and income showed weaker brain activity and poorer distractor suppression in canonical working memory areas in the left frontal cortex. Implications of this work are far‐reaching: it is now cost‐effective to localize functional brain networks in early development in low‐resource settings, paving the way for novel intervention and assessment methods.     

Rethinking the Notion of “Hostility” in African American Parenting Styles

African American parenting strategies are important in the development of prosocial behavior and are linked to empathy, self-efficacy, and racial identity. This study examined how adolescent-perceived parenting strategies (i.e., warmth, “hostility,” cultural socialization) combined to form parenting styles and how these related to positive outcomes. Participants were 358 low-income, urban southern African American high school students. Cluster analyses revealed four distinct parenting styles. Findings provide evidence that Eurocentric norms are inadequate for understanding socialization in African American families. Results indicate that a rethinking of what constitutes “parental hostility” is required. Implications, future research directions, and clinical application are discussed.     

Speech motor programming in hypokinetic and ataxic dysarthria

It is widely accepted that the cerebellar and basal ganglia control circuits contribute to the programming of movement. Converging evidence from neuroimaging, limb control, and neuropsychological studies suggests that (1) people with cerebellar disease have reduced ability to program movement sequences in advance of movement onset and (2) people with Parkinson's disease are unable to maintain a programmed response or to rapidly switch between responses. Despite a substantial supporting literature, no studies have addressed these potential areas of speech programming disruption for speakers with ataxic and hypokinetic dysarthria. Control participants and adults with dysarthria completed speech reaction time protocols designed to capture these aspects of utterance preparation. Results provided initial support for processing deficits in speakers with ataxic and hypokinetic dysarthria that are separable from motor execution impairments.     

Neural correlates of temporal-order judgments versus those of spatial-location: deactivation of hippocampus may facilitate spatial performance

The retrieval of temporal-order versus spatial-location information was investigated using fMRI. The primary finding in the hippocampus proper, seen in region of interest analyses, was an increase in BOLD signal intensity for temporal retrieval, and a decrease in signal intensity for spatial retrieval, relative to baseline. The negative BOLD signal change with spatial memory processing, while unexpected, is consistent with the recent fMRI literature indicating decreased BOLD can be associated with neuronal activation, and it is argued that the deactivation observed here may facilitate spatial performance. Spatial-location judgments also yielded a stronger (positive) response in the right midfrontal gyrus, while temporal-order judgments (autobiographic condition only) showed greater activity in the left superior temporal gyrus, suggesting greater working memory demands and greater semantization for each judgment type, respectively. Finally, all conditions activated the left midfrontal gyrus, although autobiographic memories showed additional activity in the medial frontal gyrus.     

Neural correlates of bimodal speech and gesture comprehension

The present study examined the neural correlates of speech and hand gesture comprehension in a naturalistic context. Fifteen participants watched audiovisual segments of speech and gesture while event-related potentials (ERPs) were recorded to the speech. Gesture influenced the ERPs to the speech. Specifically, there was a right-lateralized N400 effect-reflecting semantic integration-when gestures mismatched versus matched the speech. In addition, early sensory components in bilateral occipital and frontal sites differentiated speech accompanied by matching versus non-matching gestures. These results suggest that hand gestures may be integrated with speech at early and late stages of language processing.     

Factor structure and stability of the Anxiety Sensitivity Index in a longitudinal study of anxiety disorder patients

The past decade witnessed considerable debate over the factor structure of the Anxiety Sensitivity Index (ASI), with an eventual consensus emerging that supported a hierarchically organized factor structure. The present study attempted to replicate and examine the overall stability and utility of the hierarchical ASI factor pattern using a large sample of outpatients participating in an ongoing longitudinal study of anxiety disorders. Results supported a hierarchical factor structure for the ASI consisting of three lower-order factors measuring physical concerns, mental incapacitation concerns, and social concerns, all of which loaded significantly on a single second-order factor. Correlational analyses show good test-retest reliability and consistent patterns of intercorrelation for these factor-derived subscales across a 10-month time frame. Additional analyses provide support for the discriminant validity of the ASI subscales with regard to individuals with specific anxiety disorders. The theoretical implications of these findings for future evaluations of anxiety sensitivity are discussed.
