Dissociable Early Attentional Control Mechanisms Underlying Cognitive And Affective Conflicts, Taolin Chen, Keith M. Kendrick, Chunliang Feng, Shiyue Sun, Xun Yang, Xiaogang Wang, Wenbo Luo, Suyong Yang, Xiaoqi Huang, Pedro A. Valdes-Sosa, Qiyong Gong, Jin Fan, Yue-Jia Luo

Publications and Research

It has been well documented that cognitive conflict is sensitive to the relative proportion of congruent and incongruent trials. However, few studies have examined whether affective conflict processing is modulated as a function of proportion congruency (PC). To address this question we recorded eventrelated potentials (ERP) while subjects performed both cognitive and affective face-word Stroop tasks. By varying the proportion of congruent and incongruent trials in each block, we examined the extent to which PC impacts both cognitive and affective conflict control at different temporal stages. Results showed that in the cognitive task an anteriorly localized early N2 component occurred …

Validating A Measure Of Ethnic Identity In Afro-Caribbean American Students, Keisha V. Thompson

Publications and Research

The purpose of this study was to validate the Multi group Ethnic Identity Measure (MEIM) on a sample of Afro- Caribbean American college students. This investigation is unique in that it disaggregated the data to go beyond the usual labels of Black and African American used in past validation studies. Due to being subsumed in the past under such monikers, information on the ethnic identity of Afro-Caribbean American college students has largely been missing from the literature. This investigation served as a comparison to past investigations on ethnic identity in populations of African descent. The results of this study indicated …

Statistical Learning In Songbirds: From Self-Tutoring To Song Culture, Olga Fehér, Iva Ljubičić, Kenta Suzuki, Kazuo Okanoya, Ofer Tchernichovski

Publications and Research

At the onset of vocal development, both songbirds and humans produce variable vocal babbling with broadly distributed acoustic features. Over development, these vocalizations differentiate into the well-defined, categorical signals that characterize adult vocal behaviour. A broadly distributed signal is ideal for vocal exploration, that is, for matching vocal production to the statistics of the sensory input. The developmental transition to categorical signals is a gradual process during which the vocal output becomes differentiated and stable. But does it require categorical input?We trained juvenile zebra finches with playbacks of their own developing song, produced just a few moments earlier, updated continuously …

Ashamed And Afraid: A Scoping Review Of The Role Of Shame In Post-Traumatic Stress Disorder (Ptsd), Tanya Saraiya, Teresa Lopez-Castro

Publications and Research

Background: Despite considerable progress in the treatment of post-traumatic stress disorder (PTSD), a large percentage of individuals remain symptomatic following gold-standard therapies. One route to improving care is examining affective disturbances that involve other emotions beyond fear and threat. A growing body of research has implicated shame in PTSD’s development and course, although to date no review of this specific literature exists. This scoping review investigated the link between shame and PTSD and sought to identify research gaps. Methods: A systematic database search of PubMed, PsycInfo, Embase, Cochrane, and CINAHL was conducted to find original quantitative research related to shame …

Burnout Et Dépression, Entre Normal Et Pathologique? Histoire D’Une Différenciation Hasardeuse, Bianchi Renzo, Irvin Sam Schonfeld, Eric Laurent

Publications and Research

Initial described in the 1970s, the burnout syndrome has been difficult to characterize. It has been difficult to distinguish it from both clinical and subclinical depressive syndromes. In this chapter, we present a logical analysis of the distinction between burnout and depression. We synthesize the results of studies that bear on that distinction. We find that methodological and the historical separation of two lines of research as well as the lack of articulation between dimensional and categorical approaches to psychopathology.

The Capacity Of Cognitive Control Estimated From A Perceptual Decision Making Task, Tingting Wu, Alexander J. Dufford, Melissa-Ann Mackie, Laura J. Egan, Jin Fan

Publications and Research

Cognitive control refers to the processes that permit selection and prioritization of information processing in different cognitive domains to reach the capacity-limited conscious mind. Although previous studies have suggested that the capacity of cognitive control itself is limited, a direct quantification of this capacity has not been attempted. In this behavioral study, we manipulated the information rate of cognitive control by parametrically varying both the uncertainty of stimul measured as information entropy and the exposure time of the stimuli. We used the relationship between the participants’ response accuracy and the information rate of cognitive control (in bits per second, bps) …

Statistical Learning In Specific Language Impairment And Autism Spectrum Disorder: A Meta-Analysis, Rita Obeid, Patricia J. Brooks, Kasey L. Powers, Kristen Gillespie-Lynch, Jarrad A. G. Lum

Publications and Research

Impairments in statistical learning might be a common deficit among individuals with Specific Language Impairment (SLI) and Autism Spectrum Disorder (ASD). Using metaanalysis, we examined statistical learning in SLI (14 studies, 15 comparisons) and ASD (13 studies, 20 comparisons) to evaluate this hypothesis. Effect sizes were examined as a function of diagnosis across multiple statistical learning tasks (Serial Reaction Time, Contextual Cueing, Artificial Grammar Learning, Speech Stream, Observational Learning, and Probabilistic Classification). Individuals with SLI showed deficits in statistical learning relative to age-matched controls. In contrast, statistical learning was intact in individuals with ASD relative to controls. Effect sizes did …

Inducing Application Of Interdisciplinary Frameworks: Experiences From The Domains Of Information Literacy And Responsible Conduct Of Research, Anne E. Leonard, Jean E. Hillstrom

Publications and Research

Constructivist frameworks for information literacy and research ethics can be developed and nurtured in the context of an interdisciplinary course. Using the frameworks of two disciplines, students went on an experiential journey in support of ethics foundations through guest lectures and active learning exercises. This study describes the development and content of the responsible conduct of research and information literacy modules and discusses the role of each in an interdisciplinary course. Learning goals for both modules were evaluated by examining student responses in a free-writing exercise at the end of the semester, concluding with a discussion of the structural and …

Associations Between Mental Health And Ebola-Related Health Behaviors: A Regionally Representative Cross-Sectional Survey In Post-Conflict Sierra Leone, Theresa S. Betancourt, Robert T. Brennan, Patrick Vinck, Tyler J. Vanderweele, Dayo Spencer-Walters, Joshua Jeong, Adeyinka M. Akinsulure-Smith, Phuong Pham

Publications and Research

Background

Little attention has been paid to potential relationships between mental health, trauma, and personal exposures to Ebola virus disease (EVD) and health behaviors in post-conflict West Africa. We tested a conceptual model linking mental health and trauma to EVD risk behaviors and EVD prevention behaviors.

Methods and Findings

Using survey data from a representative sample in the Western Urban and Western Rural districts of Sierra Leone, this study examines associations between war exposures, post-traumatic stress disorder (PTSD) symptoms, depression, anxiety, and personal EVD exposure (e.g., having family members or friends diagnosed with EVD) and EVD-related health behaviors among 1,008 …

Venlafaxine Treatment Reduces The Deficit Of Executive Control Of Attention In Patients With Major Depressive Disorder, Yanghua Tian, Jing Du, Alfredo Spagna, Melissa-Ann Mackie, Xiaosi Gu, Yi Dong, Jin Fan, Kai Wang

Publications and Research

Attention plays an essential role in supporting other cognitive functions and behavior, and disturbance of attention is one of the most common symptoms in major depressive disorder (MDD). Although treatment with venlafaxine for MDD symptoms has been shown to reduce deficits in cognition and emotion regulation, it remains unclear whether venlafaxine improves specific attentional functions. We used the Attention Network Test to measure the attentional functions of alerting, orienting, and executive control before and after treatment with venlafaxine in patients with MDD compared to untreated healthy controls. Before treatment, the MDD group showed a selective impairment in alerting and executive …

Using The Visual World Paradigm To Study Retrieval Interference In Spoken Language Comprehension, Irina A. Sekerina, Luca Campanelli, Julie A. Van Dyke

Publications and Research

The cue-based retrieval theory (Lewis et al., 2006) predicts that interference from similar distractors should create difficulty for argument integration, however this hypothesis has only been examined in the written modality. The current study uses the Visual World Paradigm (VWP) to assess its feasibility to study retrieval interference arising from distractors present in a visual display during spoken language comprehension. The study aims to extend findings from Van Dyke and McElree (2006), which utilized a dual-task paradigm with written sentences in which they manipulated the relationship between extra-sentential distractors and the semantic retrieval cues from a verb, to the spoken …

Decisions At The Brink: Locomotor Experience Affects Infants’ Use Of Social Information On An Adjustable Drop-Off, Lana B. Karasik, Catherine S. Tamis-Lemonda, Karen E. Adolph

Publications and Research

How do infants decide what to do at the brink of a precipice? Infants could use two sources of information to guide their actions: perceptual information generated by their own exploratory activity and social information offered by their caregivers. The current study investigated the role of locomotor experience in using social information—both encouragement and discouragement—for descending drop-offs. Mothers of 30 infants (experienced 12-month-old crawlers, novice 12-month-old walkers, and experienced 18-month-old walkers) encouraged and discouraged descent on a gradation of dropoffs (safe “steps” and risky “cliffs”). Novice walkers descended more frequently than experienced crawlers and walkers and fell while attempting to …

The Benefits Of Multicultural Eclectic Service Delivery, Eugena Griffin

Publications and Research

To date, Blacks in America are often misdiagnosed or mistreated due to the failure of mental health practitioners to provide services from a multicultural eclectic purview. It is necessary to attend to the past and present influences of psychosocial variables related to real and perceived discrimination on minority achievement, behavior, and clinically health outcomes. When providers do not take into consideration these factors, they have a limited conceptualization of their clients’ needs. Such psychosocial variables can exacerbate behaviors, symptoms, and at times be the antecedent that onset those symptoms. Thus, it is imperative that health providers learn methods to investigate …

Barack Obama Blindness (Bob): Absence Of Visual Awareness To A Single Object, Marjan Persuh, Robert D. Melara

Publications and Research

In two experiments, we evaluated whether a perceiver’s prior expectations could alone obliterate his or her awareness of a salient visual stimulus. To establish expectancy, observers first made a demanding visual discrimination on each of three baseline trials. Then, on a fourth, critical trial, a single, salient and highly visible object appeared in full view at the center of the visual field and in the absence of any competing visual input. Surprisingly, fully half of the participants were unaware of the solitary object in front of their eyes. Dramatically, observers were blind even when the only stimulus on display was …

Attention Strongly Modulates Reliability Of Neural Responses To Naturalistic Narrative Stimuli, Jason J. Ki, Simon P. Kelly, Lucas C. Parra

Publications and Research

Attentional engagement is a major determinant of how effectively we gather information through our senses. Alongside the sheer growth in the amount and variety of information content that we are presented with through modern media, there is increased variability in the degree to which we “absorb” that information. Traditional research on attention has illuminated the basic principles of sensory selection to isolated features or locations, but it provides little insight into the neural underpinnings of our attentional engagement with modern naturalistic content. Here, we show inhumansubjects that the reliability of an individual’s neural responses with respect to a larger group …

Classification Accuracy Of Mixed Format Tests: A Bi-Factor Item Response Theory Approach, Wei Wang, Fritz Drasgow, Liwen Liu

Publications and Research

Mixed format tests (e.g., a test consisting of multiple-choice [MC] items and constructed response [CR] items) have become increasingly popular. However, the latent structure of item pools consisting of the two formats is still equivocal. Moreover, the implications of this latent structure are unclear: For example, do constructed response items tap reasoning skills that cannot be assessed with multiple choice items? This study explored the dimensionality of mixed format tests by applying bi-factor models to 10 tests of various subjects from the College Board’s Advanced Placement (AP) Program and compared the accuracy of scores based on the bi-factor analysis with …

Rumination And Rebound From Failure As A Function Of Gender And Time On Task, Ronald C. Whiteman, Jennifer A. Mangels

Publications and Research

Rumination is a trait response to blocked goals that can have positive or negative outcomes for goal resolution depending on where attention is focused. Whereas “moody brooding” on affective states may be maladaptive, especially for females, “reflective pondering” on concrete strategies for problem solving may be more adaptive. In the context of a challenging general knowledge test, we examined how Brooding and Reflection rumination styles predicted students’ subjective and event-related responses (ERPs) to negative feedback, as well as use of this feedback to rebound from failure on a later surprise retest. For females only, Brooding predicted unpleasant feelings after failure …

A Mendelian Randomization Study Of Testosterone And Cognition In Men, Jie Zhao, Tai Hing Lam, Chaoqiang Jiang, Stacey S. Cherny, Bin Liu, Kar Keung Cheng, Weisen Zhang, Gabriel M. Leung, C Mary Schooling

Publications and Research

Testosterone replacement for older men is increasingly common, with some observations suggesting a protective effect on cognitive function. We examined the association of endogenous testosterone with cognitive function among older men in a Mendelian randomization study using a separate-sample instrumental variable (SSIV) analysis estimator to minimize confounding and reverse causality. A genetic score predicting testosterone was developed in 289 young Chinese men from Hong Kong, based on selected testosterone-related single nucleotide polymorphisms (rs10046, rs1008805 and rs1256031). The association of genetically predicted testosterone with delayed 10-word recall score and Mini-Mental State Examination (MMSE) score was assessed at baseline and follow-up using …

Neighborhood Matters: The Impact Of Hispanic Ethnic Density On Future Depressive Symptoms 1-Year Following An Acs Event Among Hispanic Patients, Ellen-Ge Denton, Jonathan Shaffer, Carmela Alcantara, Esteban Cadermil

Publications and Research

The Ethnic Density hypothesis posits that living around others from similar ethnic backgrounds reduces the risk of adverse mental health outcomes such as depression. Contrary to this hypothesis, previous work has shown that Hispanic ethnic density is cross-sectionally associated with increased depressive symptom severity among patients hospitalized with an acute coronary syndrome (ACS; myocardial infarction or unstable angina pectoris). To date, no study has examined the prospective association of Hispanic ethnic density on long-term depressive symptom severity following an acute medical event. We prospectively assessed the impact of Hispanic ethnic density on depressive symptoms, 1-year following an ACS event, among …

The Effects Of Changing Attention And Context In An Awake Offline Processing Period On Visual Long-Term Memory, Timothy M. Ellmore, Anna Feng, Kenneth Ng, Luthfunnahar Dewan, James C. Root

Publications and Research

There is accumulating evidence that sleep as well as awake offline processing is important for the transformation of new experiences into long-term memory (LTM). Yet much remains to be understood about how various cognitive factors influence the efficiency of awake offline processing. In the present study we investigated how changes in attention and context in the immediate period after exposure to new visual information influences LTM consolidation. After presentation of multiple naturalistic scenes within a working memory paradigm, recognition was assessed 30 min and 24 h later in three groups of subjects. One group of subjects engaged in a focused …

An Event-Related Potential Study Of Social Information Processing In Adolescents, Danielle Difilipo, Jillian Grose-Fifer

Publications and Research

Increased social awareness is a hallmark of adolescence. The primary aim of this eventrelated potential study was to investigate whether adolescents, in comparison to adults, would show relatively enhanced early neural processing of complex pictures containing socially-relevant information. A secondary aim was to investigate whether there are also gender and age differences in the ways adolescents and adults process social and nonsocial information. We recorded EEGs from 12–17 year-olds and 25–37 year-olds (N = 59) while they viewed pleasant pictures from the International Affective Picture System. We found age-related amplitude differences in the N1 and the LPP, and gender-related differences …

Burnout’S Prevalence Estimations: A House Of Cards?, Renzo Bianchi, Irvin Sam Schonfeld, Eric Laurent

Publications and Research

Elmariah et al. (2016) found that 65% of the internal medicine residents who were assessed suffered from burnout. We have 3 concerns about the conclusion. First, the authors used a cutoff score on a burnout measure that is problematic because (a) it is devoid of theoretical or clinical grounding and (b) burnout items were formatted in an unorthodox manner, and (c) including residents who responded "neutral" to a symptom item among those identified as burned out. Second, the authors identified as burned out residents who worked on the night float rotation although the data suggest otherwise. Third information on symptom …

Burnout And Depression: Label-Related Stigma, Help-Seeking, And Syndrome Overlap, Renzo Bianchi, Jay Verkuilen, Romain Brisson, Irvin Sam Schonfeld, Eric Laurent

Publications and Research

We investigated whether burnout and depression differed in terms of public stigma and help-seeking attitudes and behaviors. Secondarily, we examined the overlap of burnout and depressive symptoms. A total of 1046 French schoolteachers responded to an Internet survey in November–December 2015. The survey included measures of public stigma, help-seeking attitudes and behaviors, burnout and depressive symptoms, self-rated health, neuroticism, extraversion, history of anxiety or depressive disorder, social desirability, and sociodemographic variables.The burnout label appeared to be less stigmatizing than the depression label. In either case, however, fewer than 1% of the participants exhibited stigma scores signaling agreement with the proposed …

Burnout And Depression In Psychiatric Residents, Irvin Sam Schonfeld, Eric Laurent, Pierre Vandel, Renzo Bianchi

Publications and Research

Kealy et al. (2016) found that 21% of psychiatric residents were suffering symptoms of burnout. A number of problems call that finding into question. First, the writers used a one-item measure to assess burnout. Second, mounting evidence suggests that burnout is a depressive syndrome. Third, unresolvable job stress is related to depression. Given burnout's overlap with depression and the diagnostic blur around burnout, research on the impact of job stress should connect with depression, which is nosologically well characterized and diagnosable using clinically validated instruments.

Burnout Is Associated With A Depressive Cognitive Style, Renzo Bianchi, Irvin Sam Schonfeld

Publications and Research

We examined whether burnout is associated with a depressive cognitive style, understood as a combination of dysfunctional attitudes, ruminative responses, and pessimistic attributions. A total of 1386 U.S. public school teachers were included—1063 women (M_age: 42.73, SD_age = 11.36) and 323 men (M_age: 44.60, SD_age = 11.42). Burnout was assessed with the Shirom–Melamed Burnout Measure (SMBM). Dysfunctional attitudes were measured with the Dysfunctional Attitude Scale Short Form, ruminative responses with the Ruminative Responses Scale, and pessimistic attributions with the Depressive Attributions Questionnaire. For comparative purposes, depression was assessed using the 9-item depression module of the …

On The Dead End Of Current Research On Burnout's Prevalence, Renzo Bianchi, Irvin Sam Schonfeld, Eric Laurent

Publications and Research

Dimou et al. (2016) concluded that >50% of surgeons experience burnout. For three reasons, we think that such conclusions are unwarranted. First, there are no consensual or binding diagnostic criteria for burnout. Second, recent research (e.g., Bianchi, Schonfeld, & Laurent, 2015) suggests that burnout is actually a depressive syndrome. Finally, we note that researchers’ recommendations about stress-reducing organizational changes often remain incantatory because they insufficiently consider the economic issues and macrosocial power relationships that can hamper the recommendations’ implementation. Current practices in burnout research have led to an accumulation of results, the clinical meaning of which is obscure.
