Lateralized Difference In Tympanic Membrane Temperature: Emotion And Hemispheric Activity, Ruth E. Propper, Tad T. Brunyé Mar 2019

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 Mar 2019

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 …


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 Mar 2019

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 Mar 2019

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 …


An Expanded Conceptualization And A New Measure Of Compulsive Buying, Nancy Ridgway, Monika Kukar-Kinney, Kent B. Monroe Jun 2015

An Expanded Conceptualization And A New Measure Of Compulsive Buying, Nancy Ridgway, Monika Kukar-Kinney, Kent B. Monroe

Nancy Ridgway

Drawing on the theoretical foundation of obsessive‐compulsive spectrum disorder, this article develops an expanded conceptualization and new measure of consumers’ proclivity to buy compulsively. Compulsive buying is defined as a consumer’s tendency to be preoccupied with buying that is revealed through repetitive buying and a lack of impulse control over buying. This measure includes dimensions of both obsessive‐compulsive and impulse‐control disorders. By measuring income‐dependent items or consequences of compulsive buying separately from the compulsive‐buying scale, we develop a measure that has a strong theoretical foundation, well‐documented psychometric properties, and an ability to be applied to general consumer populations.


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 May 2015

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, …


Faster Than The Speed Of Rejection: Object Identification Processes During Visual Search For Multiple Targets, Hayward J. Godwin, Stephen Walenchok, Joseph W. Houpt, Michael C. Hout, Stephen D. Goldinger Jan 2015

Faster Than The Speed Of Rejection: Object Identification Processes During Visual Search For Multiple Targets, Hayward J. Godwin, Stephen Walenchok, Joseph W. Houpt, Michael C. Hout, Stephen D. Goldinger

Joseph W. Houpt

When engaged in a visual search for two targets, participants are slower and less accurate in their responses, relative to their performance when searching for singular targets. Previous work on this “dual-target cost” has primarily focused on the breakdown of attention guidance when looking for two items. Here, we investigated how object identification processes are affected by dual-target search. Our goal was to chart the speed at which distractors could be rejected, in order to assess whether dual-target search impairs object identification. To do so, we examined the capacity coefficient, which measures the speed at which decisions can be made, …


Can Two Dots Form A Gestalt? Measuring Emergent Features With The Capacity Coefficient, Robert X.D. Hawkins, Joseph W. Houpt, Ami Eidels, James T. Townsend Jan 2015

Can Two Dots Form A Gestalt? Measuring Emergent Features With The Capacity Coefficient, Robert X.D. Hawkins, Joseph W. Houpt, Ami Eidels, James T. Townsend

Joseph W. Houpt

While there is widespread agreement among vision researchers on the importance of some local aspects of visual stimuli, such as hue and intensity, there is no general consensus on a full set of basic sources of information used in perceptual tasks. Gestalt theories place particular value on emergent features, which are based on the higher-order relationships among elements of a stimulus rather than local properties. Thus, arbitrating between different accounts of features is an important step in arbitrating between local and Gestalt theories of perception in general. In this paper, we present the capacity coefficient from Systems Factorial Technology (SFT) …


Working Memory’S Workload Capacity, Andrew Heathcote, James R. Coleman, Ami Eidels, Jason M. Watson, Joseph W. Houpt, David L. Strayer Jan 2015

Working Memory’S Workload Capacity, Andrew Heathcote, James R. Coleman, Ami Eidels, Jason M. Watson, Joseph W. Houpt, David L. Strayer

Joseph W. Houpt

We examined the role of dual-task interference in working memory using a novel dual 2-back task that requires a redundant-target response (i.e., that neither the auditory nor visual stimulus occurred two back vs. one or both occurred two back) on every trial. Comparisons with performance on single 2 back trials (i.e., with only auditory or only visual stimuli) showed dual-task demands reduced both speed and accuracy. Our task design enabled a novel application of Townsend and Nozawa’s (1995) workload capacity measure, which revealed that the decrement in dual 2-back performance was mediated by sharing of a limited amount of processing …


Mental Chronometry Measured By Electromyography In Cognitive Experiments Demanding Movement For Response Elicitation, Mohammad Abdolvahab, Miguel Moreno, Nigel Stepp, Daniela Vaz, Michael Turvey Jul 2013

Mental Chronometry Measured By Electromyography In Cognitive Experiments Demanding Movement For Response Elicitation, Mohammad Abdolvahab, Miguel Moreno, Nigel Stepp, Daniela Vaz, Michael Turvey

Mohammad Abdolvahab

The classical button pressing in reaction time experiments has shown to be limited in revealing underlying mental chronometry of cognitive processes. We inquired if it would be possible to unfold the timing of muscle activations in preparation to execute a movement (the so called anticipatory postural adjustments) in response to a cognitive demand in a couple of experiments. We asked our participants to stand in front of a computer screen and respond by raising their arm to a horizontal position. We recorded electromyographic activity of right and left biceps femoris, erector spinae and deltoid together with kinematic angular movement of …


Living Large: The Powerful Overestimate Their Own Height, Michelle M. Duguid, Jack A. Goncalo Aug 2011

Living Large: The Powerful Overestimate Their Own Height, Michelle M. Duguid, Jack A. Goncalo

Jack Goncalo

Three experiments tested the prediction that individuals’ experience of power influences perceptions of their own height. Power decreased judgments of an object’s height relative to the self (Study 1), made participants overestimate their own height (Study 2) and caused participants to choose a taller avatar to represent them in a second-life game (Study 3). These results emerged regardless of whether power was experientially primed (Study 1 and 3) or manipulated through roles (Study 2). Although a great deal of research has shown that physically imposing individuals are more likely to acquire power, this work is the first to show that …
