Lateralized Difference In Tympanic Membrane Temperature: Emotion And Hemispheric Activity, Ruth E. Propper, Tad T. Brunyé

Ruth Propper

We review literature examining relationships between tympanic membrane temperature (TMT), affective/motivational orientation, and hemispheric activity. Lateralized differences in TMT might enable real-time monitoring of hemispheric activity in real-world conditions, and could serve as a corroborating marker of mental illnesses associated with specific affective dysregulation. We support the proposal that TMT holds potential for broadly indexing lateralized brain physiology during tasks demanding the processing and representation of emotional and/or motivational states, and for predicting trait-related affective/motivational orientations. The precise nature of the relationship between TMT and brain physiology, however, remains elusive. Indeed the limited extant research has sampled different participant populations …

Asymmetry In Resting Alpha Activity: Effects Of Handedness, Ruth E. Propper, Jenna Pierce, Mark W. Geisler, Stephen D. Christman, Nathan Bellorado

Ruth Propper

Frontal electroencephalographic (EEG) alpha band power during rest shows increased right, and/or decreased left, hemisphere activity under conditions of state or trait withdrawal-associated effect. Non-right-handers (NRH) are more likely to have mental illnesses and dispositions that involve such withdrawal-related effect. The aim of the study was to examine whether NRH might be characterized by increased right, relative to left, hemisphere activity during rest. Methods: The present research investigated that hypothesis by examining resting EEG alpha power in consistently-right-handed (CRH) and NRH individuals. Results: In support of the hypothesis, NRH demonstrated decreased right hemisphere alpha power, and therefore increased right hemisphere …

Findings Of An Effect Of Gender, But Not Handedness, On Self-Reported Motion Sickness Propensity, Ruth E. Propper, Frederick Bonato, Leanna Ward, Kenneth Sumner

Ruth Propper

Discrepant input from vestibular and visual systems may be involved in motion sickness; individual differences in the organization of these systems may, therefore, give rise to individual differences in propensity to motion sickness. Non-right-handedness has been associated with altered cortical lateralization of vestibular function, such that non-right-handedness is associated with left hemisphere, and right-handedness with right hemisphere, lateralized, vestibular system. Interestingly, magnocellular visual processing, responsible for motion detection and ostensibly involved in motion sickness, has been shown to be decreased in non-right-handers. It is not known if the anomalous organization of the vestibular or magnocellular systems in non-right-handers might alter …

A Combined Fmri And Dti Examination Of Functional Language Lateralization And Arcuate Fasciculus Structure: Effects Of Degree Versus Direction Of Hand Preference Author Links Open Overlay Panel, Ruth E. Propper, Lauren J. O'Donnell, Stephen Whalen, Yanmei Tie, Isaiah Norton, Ralph O. Suarez, Lilla Zollei, Alireza Radmanesh, Alexandra Golby

Ruth Propper

The present study examined the relationship between hand preference degree and direction, functional language lateralization in Broca’s and Wernicke’s areas, and structural measures of the arcuate fasciculus. Results revealed an effect of degree of hand preference on arcuate fasciculus structure, such that consistently-handed individuals, regardless of the direction of hand preference, demonstrated the most asymmetric arcuate fasciculus, with larger left versus right arcuate, as measured by DTI. Functional language lateralization in Wernicke’s area, measured via fMRI, was related to arcuate fasciculus volume in consistent-left-handers only, and only in people who were not right hemisphere lateralized for language; given the …

Superior Episodic Memory Is Associated With Interhemispheric Processing, Ruth E. Propper, Stephen D. Christman

Ruth Propper

The dependence of episodic memories on interhemispheric processing was tested. In Experiment 1, positive familial sinistrality (FS+; e.g., the presence of left-handed relatives) was associated with superior episodic memory and inferior implicit memory in comparison with negative familial sinistrality (i.e., FS-). This reflected a greater degree of interhemispheric interaction in FS+ participants, which was hypothesized as facilitating episodic memory. In Experiment 2, the authors directly manipulated inter- versus intrahemispheric processing using tests of episodic (recognition) and semantic (lexical decision) memory in which letter strings were presented twice within trial blocks. Semantic memory was superior when the 2nd presentation went to …

Why Girls? The Importance Of Developing Gender-Specific Health Promotion Programs For Adolescent Girls, Amanda Birnbaum, Tracy R. Nichols

Amanda Birnbaum

Adolescence is a time when many girls begin to develop unhealthy behaviors that can affect myriad short- and long-term health outcomes across their lifespan.2There is evidence that smoking, physical activity, and diet are habituated during adolescence, and some physiologic processes of adolescence, such as peak bone mass development, have direct effects on future health.3-4 Establishing healthy practices, beliefs and knowledge among adolescent girls will decrease morbidity and mortality among adult women and potentially affect the health of men and children through women’s role as healthcare agents. This paper provides a brief review of lifestyle health behaviors among women and girls …

Self-Management Strategies Mediate Self-Efficacy And Physical Activity, Amanda Birnbaum, Rod K. Dishman, Robert W. Motl, James F. Sallis, Andrea L. Dunn, Greg J. Welk, Ariane L. Yung, Carolyn C. Voorhees, Jared B. Jobe

Amanda Birnbaum

Self-efficacy theory proposes that girls who have confidence in their capability to be physically active will perceive fewer barriers to physical activity or be less influenced by them, be more likely to pursue perceived benefits of being physically active, and be more likely to enjoy physical activity. Self-efficacy is theorized also to influence physical activity through self-management strategies (e.g., thoughts, goals, plans, and acts) that support physical activity, but this idea has not been empirically tested.

Cognitive And Psychiatric Predictors To Psychosis In Velocardiofacial Syndrome: A 3-Year Follow-Up Study, Kevin Antshel, Robert Shprintzen, Wanda Fremont, Anne Higgins, Stephen Faraone, Wendy Kates

Robert J. Shprintzen

Objective: To predict prodromal psychosis in adolescents with velocardiofacial syndrome (VCFS). Method: 70 youth with VCFS, 27 siblings of youth with VCFS and 25 community controls were followed from childhood (Mean age = 11.8 years) into mid-adolescence (mean age 15.0 years). Psychological tests measuring intelligence, academic achievement, learning/memory, attention and executive functioning as well as measures of parent and clinician ratings of child psychiatric functioning were completed at both time point. Results: Major depressive disorder, oppositional defiant disorder, and generalized anxiety disorder diagnoses increased in the VCFS sample. With very low false positive rates, the best predictor of adolescent prodromal …

Interaction Among Gustation, Olfaction, And Vision In Flavor Identification, Michael Lauth

Michael Lauth

Even though the senses of taste, smell, and sight are distinct, there is a significant overlap among them in our perceptions of objects that helps us understand and differentiate the world. Everyone has experienced, when his or her nose gets congested, that his or her sense of taste changes as well. Many individuals do not equally understand the top-down processing with taste when someone sees objects they are about to eat. In the replicated study by our principle investigator, a random convenience sample of young adults (n=162) were recruited and tested to determine if they could taste four Jelly Belly …

Women: The Ignored Majority, Carol T. Mowbray, Daphna Oyserman, Catherine J. Lutz, Rogeair Purnell

Catherine Lutz Zois

The major thrust of psychiatric rehabilitation is to provide skill development and supports enabling individuals to function in their roles of choice. The model thus contains an underlying assumption that meaningful life roles are “chosen” roles. It therefore may tend to overlook the impact on persons’ lives of the roles that they are given. These given or ascribed roles include those based on gender, ethnicity, and socioeconomic class. Self-definitions, behaviors, beliefs, attitudes, and values are all likely to be structured within such social roles, which can also serve as important social identities (Oyserman & Markus, 1993). In spite of increased …

Relative Reward Effects On Operant Behavior: Incentive Contrast,Induction And Variety Effects, Howard Cromwell

Howard Casey Cromwell

Comparing different rewards automatically produces dynamic relative outcome effects on behavior. Eachnew outcome exposure is to an updated version evaluated relative to alternatives. Relative reward effectsinclude incentive contrast, positive induction and variety effects. The present study utilized a novelbehavioral design to examine relative reward effects on a chain of operant behavior using auditory cues.Incentive contrast is the most often examined effect and focuses on increases or decreases in behavioralperformance after value upshifts (positive) or downshifts (negative) relative to another outcome. Weexamined the impact of comparing two reward outcomes in a repeated measures design with three ses-sions: a single outcome and …

Congenital Prosopagnosia: Face-Blind From Birth, Marlene Behrmann, Galia Avidan

Marlene Behrmann

Congenital prosopagnosia refers to the deficit in face processing that is apparent from early childhood in the absence of any underlying neurological basis and in the presence of intact sensory and intellectual function. Several such cases have been described recently and elucidating the mechanisms giving rise to this impairment should aid our understanding of the psychological and neural mechanisms mediating face processing. Fundamental questions include: What is the nature and extent of the face-processing deficit in congenital prosopagnosia? Is the deficit related to a more general perceptual deficit such as the failure to process configural information? Are any neural alterations …

Polychlorinated Biphenyl Exposure Alters Oxytocin Receptor Gene Expression And Maternal Behavior In Rat, Howard Cromwell

Howard Casey Cromwell

Polychlorinated biphenyl (PCB) is a persistent organic pollutant known to induce diverse molecular and behavioral alterations. Effects of PCB exposure could be transmitted to future generations via changes in behavior and gene expression. Previous work has shown that PCB-exposure can alter social behavior. The present study extends this work by examining a possible molecular mechanism for these changes. Pregnant rats (Sprague-Dawley) were exposed through diet to a combination of non-coplanar (PCB 47 - 2,20,4,40-tetrachlorobiphenyl) and coplanar (PCB 77 - 3,30,4,40- tetrachlorobiphenyl) congeners. Maternal care behaviors were examined by evaluating the rate and quality of nest building on the last 4 …

Nimh Research Domain Criteria (Rdoc), Charles A. Sanislow, Kevin J. Quinn, Isaiah Sypher

Charles A. Sanislow, Ph.D.

The Research Domain Criteria (RDoC) project is a framework for studying domains of biological and behavioral function that cut across traditional psychiatric diagnostic boundaries with the long-term objective of creating a new nosology based on specific biobehavioral measures. The initial aim is to provide a framework to drive clinical research. One goal of RDoC is to facilitate the development of biomarkers that could eventually be used for practical clinical diagnostic purposes and allow the development of new treatments targeting specific mechanisms of mental illness. In this entry, RDoC, its development, and the ways that it may evolve are described.

The Influence Of Maternal Education On Lifetime Vulnerabilities For Chronic Stress And Heightened Physiological Reactions To Stressors, Hannah Lapp, Celia Moore, Kymberlee O'Brien

Kymberlee M. O'Brien

We examined parental education as predictors of vulnerability to biological and perceived chronic stressors into adulthood. Measures included hair cortisol (hCORT) and cardiovascular parameters as indicators of chronic stress and overall health. The community subjective social status ladder was included to examine relationships between maternal education and assessments of social standing in adult offspring. Participants (N = 107; ages 18-30; M =22.23, SD = 3.01; 50.4% female) were recruited from an urban public university and residents of surrounding low-income areas in Boston, MA. Maternal and paternal education were positively associated with change in sympathetic nervous system (SNS) recovery after a …

Emotion And Relative Reward Processing: An Investigation On Instrumental Successive Negative Contrast And Ultrasonic Vocalizations In The Rat., Howard Cromwell

Howard Casey Cromwell

Incentive contrast effects include changes in behavioral responses after a reward upshift (positive contrast) or downshift (negative contrast). Proposed influences on these behavioral changes are emotional state reactions after experiencing or anticipating a change in reward outcome. Rat ultrasonic vocalizations have been shown to be indicators of emotional state during behavior and anticipatory periods. The objective of the present study was to monitor rodent ultrasounds during incentive contrast using a classical runway procedure called instrumental successive negative contrast. The procedure is one that has been used often to examine incentive relativity because of its reliability in measuring negative contrast effects. …

Method: The study included 223 BPD patients with DSM-IV–defined co-occurring major depressive disorder (MDD) (n = 161), bipolar I disorder (n = 34), and bipolar II disorder (n = 28) who were reliably and prospectively assessed over a period of 10 years between 1997 and 2009. Proportional hazards regression analyses were used to assess the effects of improvement or …

Alexithymia And Alcohol: The Roles Of Punishment Sensitivity And Drinking Motives, Michael Lyvers, Penelope Hasking, Bonnie Albrecht, Fred Thorberg

Mike Lyvers

Alexithymia refers to difficulties identifying and describing feelings. It is suspected of being a risk factor for problematic drinking, an idea examined by this study. In 178 women and 84 men alexithymia was associated with male gender, coping motives for drinking and sensitivity to punishment. Individuals with alexithymia reported stronger coping motives and sensitivity to punishment compared to those with borderline or no alexithymia. Path analysis indicated that the relationship between the alexithymia dimension difficulties identifying feelings and coping motives was mediated by sensitivity to punishment, and the relationship between sensitivity to punishment and risky drinking was mediated by coping …

Illicit Use Of Lsd Or Psilocybin, But Not Mdma Or Nonpsychedelic Drugs, Is Associated With Mystical Experiences In A Dose-Dependent Manner, Michael Lyvers, Molly Meester

Mike Lyvers

Psychedelic drugs have long been known to be capable of inducing mystical or transcendental experiences. However, given the common “recreational” nature of much present-day psychedelic use, with typical doses tending to be lower than those commonly taken in the 1960s, the extent to which illicit use of psychedelics today is associated with mystical experiences is not known. Furthermore the mild psychedelic MDMA (“Ecstasy”) is more popular today than “full” psychedelics such as LSD or psilocybin, and the contribution of illicit MDMA use to mystical experiences is not known. The present study recruited 337 adults from the website and newsletter of …

Rash Impulsiveness And Reward Sensitivity In Relation To Risky Drinking By University Students: Potential Roles Of Frontal Systems, Michael Lyvers, Helen Duff, Vanessa Basch, Mark Edwards

Mike Lyvers

Background: Two forms of impulsivity, rash impulsiveness and reward sensitivity, have been proposed to reflect aspects of frontal lobe functioning and promote substance use. The present study examined these two forms of impulsivity as well as frontal lobe symptoms in relation to risky drinking by university students. Methods: University undergraduates aged 18–26 years completed the Alcohol Use Disorders Identification Test (AUDIT), Barratt Impulsiveness Scale (BIS-11), Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ), Frontal Systems Behavior Scale (FrSBe), and a demographics questionnaire assessing age, gender, and age of onset of weekly drinking (AOD). Results: AUDIT-defined harmful drinkers reported earlier …
