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 …

Getting A Grip On Memory: Unilateral Hand Clenching Alters Episodic Recall, Ruth E. Propper, Sean E. Mcgraw, Tad T. Brunyé

Ruth Propper

Unilateral hand clenching increases neuronal activity in the frontal lobe of the contralateral hemisphere. Such hand clenching is also associated with increased experiencing a given hemisphere’s “mode of processing.” Together, these findings suggest that unilateral hand clenching can be used to test hypotheses concerning the specializations of the cerebral hemispheres during memory encoding and retrieval. We investigated this possibility by testing the effects of a unilateral hand clenching on episodic memory. The hemispheric Encoding/Retrieval Asymmetry (HERA) model proposes left prefrontal regions are associated with encoding, and right prefrontal regions with retrieval, of episodic memories. It was hypothesized that right-hand clenching …

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 …

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.

Responding To The Challenge Of Problem Sexual Behaviour By Young People In Queensland: An Opinion, Scott Harden, Michelle Phillips, Stephen Stathis, Kerry Geritz, Tasneem Hasan, Mike Spiller, Bruce Watt, Angela Allen

Bruce Watt

There is general agreement that problematic sexual behaviour by young people is more common than was earlier believed and poses significant public health, juvenile justice and mental health difficulties for the community. A growing body of literature around the treatment of young people with inappropriate sexual behaviour has developed in recent decades. However, significant gaps remain as much of the literature is focused at the individual program level. As professionals in our jurisdiction of Queensland working in child and youth forensic mental health services, we have long been frustrated by the lack of a comprehensive, appropriately layered system of assessment …

A Feasibility Study: Emotional Freedom Techniques For Depression In Australian Adults, Peta Stapleton, Sharon Devine, Hannah Chatwin, Brett Porter, Terri Sheldon

Peta B. Stapleton

The purpose of this study was to investigate the feasibility of using Clinical Emotional Freedom Techniques (EFT) to treat Major Depressive Disorder in an adult population by way of a therapeutic group setting. Adults were assigned to EFT group treatment for a period of eight weeks. Diagnostic assessment was completed immediately pre and post treatment using the Mini International Neuropsychiatric Interview. In addition to this, self-report assessments measuring symptomatic evidence of depression were completed by the participants before the treatment, after the treatment and at three month follow-up. Comparisons with a community group were made at pre and post intervention …

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 …

Explaining The Link Between Perfectionism And Self-Forgiveness: The Mediating Roles Of Self-Acceptance And Rumination, Lee Dixon, Katherine Earl, Catherine Lutz-Zois, Jackson Goodnight, Jessica Peatee

Catherine Lutz Zois

Although recent research has begun to examine correlates of self-forgiveness, very little research has examined the association between self-forgiveness and perfectionism. This study examined this association, along with mediating mechanisms that help explain this association. Specifically, we examined the indirect relationships between both Conscientious and Self-Evaluative forms of perfectionism and episodic self-forgiveness, through both unconditional self-acceptance and rumination. Participants (N = 206) completed measures of perfectionism, unconditional self-acceptance, rumination about a specific betrayal they committed, and self-forgiveness of said betrayal. Multivariate path analyses revealed Self-Evaluative Perfectionism to be indirectly associated with self-forgiveness, through both unconditional self-acceptance and rumination. More specifically, …

Perceived Similarity And Relationship Success Among Dating Couples: An Idiographic Approach, Catherine Lutz, Angela Bradley, Jennifer Mihalik, Erika Moorman

Catherine Lutz Zois

This study utilized an idiographic approach to investigate the relation between similarity on valued characteristics and relationship success. College students (N = 247) rated their current romantic partner on perceived similarity in personality, attitudes, interests, and religious affiliation; the importance of similarity in these dimensions; and relationship satisfaction. Relationship status was assessed 6 weeks later. Results revealed significant similarity by importance interactions for religion and interests in predicting satisfaction. Participants with high perceived similarity in religion or interests reported greater satisfaction than did their low similarity counterparts, but only to the extent that they rated this type of similarity as …

Psychopathy And The Five Factor Model In A Noninstitutionalized Sample: A Domain And Facet Level Analysis, Scott R. Ross, Catherine J. Lutz, Steven E. Bailley

Catherine Lutz Zois

The current study examined the relationship of the Five Factor Model (FFM) of personality to primary and secondary psychopathic dispositions in a noninstitutionalized sample. Previous investigations suggest that Agreeableness, Conscientiousness, and Neuroticism are basic personality traits that characterize psychopathy. However, few studies have examined the relationship of the FFM to primary and secondary psychopathic attributes, respectively. In the current study, the relationship of the FFM using the NEO-PI-R to primary and secondary psychopathic dispositions was investigated in a sample of young adults. Previous findings were extended by (1) addressing the relationship of higher and lower order FFM traits (i.e., facet …

The Differential Association Between Alexithymia And Primary Versus Secondary Psychopathy, Gwendoline Cecilia Lander, Catherine J. Lutz-Zois, Mark S. Rye, Jackson A. Goodnight

Catherine Lutz Zois

Using a sample of 104 college students, this study tested the hypothesis that alexithymia is positively related to secondary (also known as “neurotic psychopathy”), but not primary psychopathy (i.e., inability to form emotional bonds with others and a fear insensitivity). Participants completed the TAS-20 (alexithymia), the LSRP (primary and secondary psychopathy), the PPI-R (psychopathy), and the trait version of the STAI (trait anxiety). The interaction between the latter two measures was used as a second index of primary and secondary psychopathy. Support was found for the study hypothesis with both methods of assessing psychopathy (i.e., the LSRP subscales or the …
