Everyday Memory In People With Down Syndrome, Yingying Yang, Zachary M. Himmelberger, Trent Robinson, Megan Davis, Frances Conners, Edward Merrill

Department of Psychology Faculty Scholarship and Creative Works

Although memory functions in people with Down Syndrome (DS) have been studied extensively, how well people with DS remember things about everyday life is not well understood. In the current study, 31 adolescents/young adults with DS and 26 with intellectual disabilities (ID) of mixed etiology (not DS) participated. They completed an everyday memory questionnaire about personal facts and recent events (e.g., school name, breakfast). They also completed a standard laboratory task of verbal long-term memory (LTM) where they recalled a list of unrelated words over trials. Results did not indicate impaired everyday memory, but impaired verbal LTM, in people with …

How Multidimensional Is Emotional Intelligence? Bifactor Modeling Of Global And Broad Emotional Abilities Of The Geneva Emotional Competence Test, Daniel Simonet, Katherine E. Miller, Kevin Askew, Kenneth Sumner, Marcello Mortillaro, Katja Schlegel

Department of Psychology Faculty Scholarship and Creative Works

Drawing upon multidimensional theories of intelligence, the current paper evaluates if the Geneva Emotional Competence Test (GECo) fits within a higher-order intelligence space and if emotional intelligence (EI) branches predict distinct criteria related to adjustment and motivation. Using a combination of classical and S-1 bifactor models, we find that (a) a first-order oblique and bifactor model provide excellent and comparably fitting representation of an EI structure with self-regulatory skills operating independent of general ability, (b) residualized EI abilities uniquely predict criteria over general cognitive ability as referenced by fluid intelligence, and (c) emotion recognition and regulation incrementally predict grade point …

An Evaluation Of Wayfinding Abilities In Adolescent And Young Adult Males With Autism Spectrum Disorder, Yingying Yang, Weijia Li, Dan Huang, Wei He, Yanxi Zhang, Edward Merrill

Department of Psychology Faculty Scholarship and Creative Works

Background

Wayfinding refers to traveling from place to place in the environment. Despite some research headway, it remains unclear whether individuals with Autism Spectrum Disorder (ASD) show strengths, weaknesses, or similarities in wayfinding compared with ability-matched typically developing (TD) controls.

Method

The current study tested 24 individuals with ASD, 24 mental-ability (MA) matched TD (MA-TD) controls, and 24 chronological-age (CA) matched TD (CA-TD) controls. Participants completed a route learning task and a survey learning task, both programmed in virtual environments, and a perspective taking task. Their parents completed questionnaires assessing their children’s everyday wayfinding activities and competence.

Results

Overall, CA-TD …

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

Department of Psychology Faculty Scholarship and Creative Works

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 …

Hemispheric Bases For Emotion And Memory, Tad T. Brunyé, Sarah R. Cavanagh, Ruth E. Propper

Department of Psychology Faculty Scholarship and Creative Works

The goal of this Research Topic was to bring together diverse scientific perspectives on lateralized brain mechanisms underlying emotion, motivation, and memory. The Topic resulted in eight articles, three of which report original research and five of which review and synthesize past research with the aim of developing new hypotheses and theory. A range of international experts with diverse backgrounds, theoretical perspectives, and experimental methods contributed to the Topic. Contributions strongly reflect this diversity, ranging from examining pupil dilation in response to viewing Rembrandt portraits to understanding how caffeine supplementation influences levels of spatial processing. In all cases, the authors …

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

Department of Psychology Faculty Scholarship and Creative Works

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 …

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

Department of Psychology Faculty Scholarship and Creative Works

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

Department of Psychology Faculty Scholarship and Creative Works

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

Department of Psychology Faculty Scholarship and Creative Works

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 …

Locus Of Control And The Age Difference In Free Recall From Episodic Memory, Paul Amrhein, Judith K. Bond, Derek Hamilton

Department of Psychology Faculty Scholarship and Creative Works

The authors investigated the relation of locus of control (LOC) to age differences in free-recall memory performance. Older and younger participants completed P. C. Duttweiler's (1984) Internal Control Index (ICI) and subsequently performed free-recall memory tasks. Compared with the younger participants, the older participants exhibited poorer recall with more intrusions and uncorrected repetition errors as well as reduced categorical clustering. For the older participants with less internal LOC, recall proportion and item-pair associative recall clustering were lower than for the older participants with more internal LOC. By contrast, the younger participants did not exhibit any LOC effects in their recall …

A Pilot Study Of Bibliotherapy To Reduce Alcohol Problems Among Patients In A Hospital Trauma Center, Paul Amrhein, Timothy Apodaca, William R. Miller, Carol R. Schermer

Department of Psychology Faculty Scholarship and Creative Works

Because alcohol use plays a major role in many injuries that require hospital care, there is increasing interest in developing interventions to address alcohol problems among emergency department and trauma center patients. The aim of the current study was to extend past research on brief interventions by investigating the use of a self-help manual to treat problem drinkers in a hospital trauma center. Forty injured patients who were either intoxicated at the time of injury or screened positive for harmful drinking were randomly assigned to receive either a brief assessment and a self-help booklet with no more than 5 minutes …

Client Commitment Language During Motivational Interviewing Predicts Drug Use Outcomes, Paul Amrhein, William R. Miller, Carolina Yahne, Michael Palmer, Laura Fulcher

Department of Psychology Faculty Scholarship and Creative Works

Client language from a motivational interview (MI) and drug use outcome were investigated. Interview videotapes of 84 drug abusers were coded for frequency and strength of utterances expressing commitment, desire, ability, need, readiness, and reasons to change or maintain their habit. Cluster analysis of proportion days abstinent (PDA) revealed 3 groups: high PDA at intake and follow-up (3, 6, 9, 12 months; maintainers); low intake PDA/high follow-up PDA (changers); and low intake PDA/low to moderate follow-up PDA (stragglers). Distinct group patterns emerged for commitment strength (CS) during MI. Clients dishonest in checklist self-report exhibited CS similar to stragglers. CS for …

Revisiting The Picture-Superiority Effect In Symbolic Comparisons: Do Pictures Provide Privileged Access?, Paul Amrhein, Mark Mcdaniel, Paula Waddill

Department of Psychology Faculty Scholarship and Creative Works

In 4 experiments, symbolic comparisons were investigated to test semantic-memory retrieval accounts espousing processing advantages for the picture over word stimuli. In Experiment 1, participants judged pairs of animal names or pictures by responding to questions probing concrete or abstract attributes (texture or size, ferocity or intelligence). Per pair, attributes were salient or nonsalient concerning their prerated relevance to animals being compared. Distance (near or far) between attribute magnitudes was also varied. Pictures did not significantly speed responding relative to words across all other variables. Advantages were found for far attribute magnitudes (i.e., the distance effect) and salient attributes. The …

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

Department of Psychology Faculty Scholarship and Creative Works

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 …
