Mixed-Case Format And Lexical Decision Performance: Initial Uppercase Is Special, Julia C. Harvey Azzolina, Lois M. Rotuno, April D. Butler Waltonen, Albert F. Smith

Undergraduate Research Posters 2014

Previous research has shown that there are phenomena that may require a route to word identification by means other than through letters. For example, in a lexical decision task, in which an experimental participant is asked to determine if a string of letters is a word or not, responses to items in a MIXed caSE format are slower than to items in PURE UPPERCASE or pure lowercase formats. In this experiment, we investigated the effect of different mixed-case formats on lexical decision performance, focusing on the type and location of the case transition. Twenty-four students participated in a lexical decision …

Happiness At Work: Rules For Employee Satisfaction And Engagement, Femi Cadmus

Femi Cadmus

The concept of employee satisfaction and engagement is not new. Quite recently, however, there appears to be renewed interest in positive psychology, tracking what makes for happiness in general, and how this translates in the workplace. Cultivating and maintaining a climate and culture which breeds happy, motivated, and productive employees in a library setting requires hard work. Happiness in the workplace is not unattainable, but it requires a concerted plan of action and consistent effort by managers. Managers also need to take steps to make sure that their own personal and work needs are being taken care off to avert …

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. …

Speaking Two Languages Enhances An Auditory But Not A Visual Neural Marker Of Cognitive Inhibition, Mercedes Fernandez, Juliana Acosta, Kevin Douglass, Nikita Doshi, Jaime L. Tartar

Faculty Articles

The purpose of the present study was to replicate and extend our original findings of enhanced neural inhibitory control in bilinguals. We compared English monolinguals to Spanish/English bilinguals on a non-linguistic, auditory Go/NoGo task while recording event-related brain potentials. New to this study was the visual Go/NoGo task, which we included to investigate whether enhanced neural inhibition in bilinguals extends from the auditory to the visual modality. Results confirmed our original findings and revealed greater inhibition in bilinguals compared to monolinguals. As predicted, compared to monolinguals, bilinguals showed increased N2 amplitude during the auditory NoGo trials, which required inhibitory control, …

Predicting Survey Responses: How And Why Semantics Shape Survey Statistics On Organizational Behaviour, Ketil Arnulf, Kai R. Larsen, Øyvind Martinsen, Chih How Bong

Kai R.T. Larsen

Some disciplines in the social sciences rely heavily on collecting survey responses to detect empirical relationships among variables. We explored whether these relationships were a priori predictable from the semantic properties of the survey items, using language processing algorithms which are now available as new research methods. Language processing algorithms were used to calculate the semantic similarity among all items in state-of-the-art surveys from Organisational Behaviour research. These surveys covered areas such as transformational leadership, work motivation and work outcomes. This information was used to explain and predict the response patterns from real subjects. Semantic algorithms explained 60–86% of the …

The Relationship Between Mindfulness And Burnout Among Master Of Social Work Students, Jolanta Maria Piatkowska

Dissertations and Theses

Social work students frequently endure elevated levels of prolonged stress and psychological affliction that might result in serious consequences, such as development of burnout. Some experts suggest that burnout originates in the exposure to chronic interpersonal stressors in the work environment. Yet, there is emerging evidence suggesting that mindfulness practice might be beneficial in alleviating stress. Thus, the purpose of this exploratory study was to examine the relationship between mindfulness and burnout among Master of Social Work students. Burnout, mindfulness, religiosity, spirituality and their potential relationship were discussed and related to previous scholarly literature. Specifically, this study focused on testing …

Not Just Fun And Games: A Review Of College Drinking Games Research From 2004 To 2013, Byron L. Zamboanga, Shannon R. Kenney, Kathryne Van Tyne, Janine V. Olthuis, Christopher J. Correia, Lindsay S. Ham, Brian Borsari

Heads Up!

Drinking games are a high-risk social drinking activity consisting of rules and guidelines that determine when and how much to drink (Polizzotto et al., 2007). Borsari's (2004) seminal review paper on drinking games in the college environment succinctly captured the published literature as of February 2004. However, research on college drinking games has grown exponentially during the last decade, necessitating an updated review of the literature. This review provides an in-depth summary and synthesis of current drinking games research (e.g., characteristics of drinking games, and behavioral, demographic, social, and psychological influences on participation) and suggests several promising areas for future …

Sharp Emergence Of Feature-Selective Sustained Activity Along The Dorsal Visual Pathway., Diego Mendoza-Halliday, Santiago Torres, Julio C Martinez-Trujillo

Brain and Mind Institute Researchers' Publications

Sustained activity encoding visual working memory representations has been observed in several cortical areas of primates. Where along the visual pathways this activity emerges remains unknown. Here we show in macaques that sustained spiking activity encoding memorized visual motion directions is absent in direction-selective neurons in early visual area middle temporal (MT). However, it is robustly present immediately downstream, in multimodal association area medial superior temporal (MST), as well as and in the lateral prefrontal cortex (LPFC). This sharp emergence of sustained activity along the dorsal visual pathway suggests a functional boundary between early visual areas, which encode sensory inputs, …

Laterality Influences Cognitive Performance In Rainbowfish Melanotaenia Duboulayi, Anne-Laurence Bibost, Culum Brown

Sentience Collection

Cerebral lateralization has been suggested to convey a selective advantage to individuals by enhancing their cognitive abilities. Few, however, have explicitly compared the cognitive ability of animals with strongly contrasting laterality. Here, we examined the influence of laterality on learning performance in the crimson spotted rainbowfish, Melanotaenia duboulayi, using a classical conditioning paradigm. We also compared the learning ability of wild caught and captive-reared fish to examine the influence of rearing environment on cognitive performance. Laterality was established by observing which eye fish preferred to use while viewing their mirror image. Subjects were then conditioned to associate the appearance of …

Emotional Engagements Predict And Enhance Social Cognition In Young Chimpanzees, Kim A. Bard, Roger Bakeman, Sarah T. Boysen, David A. Leavens

Sentience Collection

Social cognition in infancy is evident in coordinated triadic engagements, that is, infants attending jointly with social partners and objects. Current evolutionary theories of primate social cognition tend to highlight species differences in cognition based on human-unique cooperative motives. We consider a developmental model in which engagement experiences produce differential outcomes. We conducted a 10-year-long study in which two groups of laboratory-raised chimpanzee infants were given quantifiably different engagement experiences. Joint attention, cooperativeness, affect, and different levels of cognition were measured in 5- to 12-month-old chimpanzees, and compared to outcomes derived from a normative human database. We found that joint …

Behaviour Of Horses In A Judgment Bias Test Associated With Positive Or Negative Reinforcement, Sabrina Briefer Freymond, Elodie F. Briefer, Anja Zollinger, Yveline Gindrat-Von Allmen, Christa Wyss, Iris Bachmann

Ethology Collection

Moods can influence our judgment of ambiguous stimuli as positive or negative. Measuring judgment bias in animals is a promising method to objectively assess their emotional states. Our study aimed to develop a cognitive bias test in horses, in order to assess the effect of training using positive reinforcement (PR) or negative reinforcement (NR) on their emotional states. We trained 12 mares to discriminate between a rewarded and a non-rewarded location situated on each side of a paddock. The mares were then trained during five days to perform several exercises using PR (n = 6) for one group, and NR …

Why Primate Models Matter, Kimberley A. Phillips, K. L. Bales, J. P. Capitanio, A. Conley, P. W. Czoty, B. A. 'T Hart, William D. Hopkins, S.L. Hu, L. A. Miller, M. A. Nader, P. W. Nathanielsz, J. Rogers, C. A. Shively, M.L. Voytko

Psychology Faculty Research

Research involving nonhuman primates (NHPs) has played a vital role in many of the medical and scientific advances of the past century. NHPs are used because of their similarity to humans in physiology, neuroanatomy, reproduction, development, cognition, and social complexity – yet it is these very similarities that make the use of NHPs in biomedical research a considered decision. As primate researchers, we feel an obligation and responsibility to present the facts concerning why primates are used in various areas of biomedical research. Recent decisions in the United States, including the phasing out of chimpanzees in research by the National …

Transgressors’ Guilt And Shame: A Longitudinal Examination Of Forgiveness Seeking, Blake M. Riek, Lindsey M. Root Luna, Chelsea A. Schnabelrauch

University Faculty Publications and Creative Works

The current study examines forgiveness from the perspective of the transgressor, an often overlooked aspect of interpersonal forgiveness and a model of forgiveness seeking is proposed. Using a 2-wave longitudinal design, 166 participants completed measures of the characteristics of their transgressions, their feelings of guilt and shame, and their forgiveness-seeking behaviors. Cross-lagged correlational analysis indicated that guilt at time 1 was related to forgiveness seeking at time 2, but the opposite was not true. Path analyses revealed that guilt mediated the impact of transgression and relationship factors (i.e., transgression severity, responsibility, rumination, and relationship commitment) on forgiveness-seeking behavior over time. …

Socialising Piglets In Lactation Positively Affects Their Post-Weaning Behaviour, Talia Morgan, John Pluske, David Miller, Teresa Collins, Anne L. Barnes, Françoise Wemelsfelder, Patricia A. Fleming

Sentience Collection

Although commercial farrowing sheds keep individual litters separated, previous studies have suggested that housing systems that allow socialisation of piglets pre-weaning can reduce aggression after weaning. This study tested whether pigs socialised with non-littermates pre-weaning would show less aggression during mixing at weaning (when piglets are taken from their sows and mixed in group housing), and whether socialisation influenced the time budgets or behavioural expression of piglets at weaning. In total, 353 piglets were followed from birth through to one week after weaning. Piglets from 24 sows were allowed to socialise in groups of four litters (‘socialised’ treatment group) from …

Anthropomorphism, Anthropectomy, And The Null Hypothesis, Kristin Andrews, Brian Huss

Experimentation Collection

We examine the claim that the methodology of psychology leads to a bias in animal cognition research against attributing ‘‘anthropomorphic’’ properties to animals (Sober in Thinking with animals: new perspectives on anthropomorphism. Columbia University Press, New York, pp 85–99, 2005; de Waal in Philos Top 27:225–280, 1999). This charge is examined in light of a debate on the role of folk psychology between primatologists who emphasize similarities between humans and other apes, and those who emphasize differences. Weargue that while in practice there is sometimes bias, either in the formulation of the null hypothesis or in the preference of Type-II …

The Impact Of Physical Activity On Depressed Mood In Older Seventh-Day Adventists, Benjamin J. Silber

Loma Linda University Electronic Theses, Dissertations & Projects

Research has shown physical activity (PA) to result in a reduction in depressed mood. The effects have been examined for different age groups, however, it is unclear whether PA effects differ in older adults. A prospective cohort study (N = 6,463) examined duration and intensity of PA in relation to mood in the Biopsychosocial Religion and Health Study (BRHS). Depressed mood indices were expected to be predicted by lower levels of PA and individuals in younger age groups were expected to receive a greater reduction in depressed mood after PA than those in older age groups. Previous PA (minutes of …

Collaborative Treatment Of Late-Life Depression In Primary Care (Germanimpact): Study Protocol Of A Cluster-Randomized Controlled Trial, Iris Wernher, Frederike Bjerregaard, Iris Tinsel, Christiane Bleich, Sigrid Boczor, Thomas Kloppe, Martin Scherer, Martin Härter, Wilhelm Niebling, Hans-Helmut König, Michael Hüll

Institute on Aging Publications

Background: Depression is not a normal side effect of aging, however it is one of the most prevalent mental health issues in later life, imposing a tremendous burden on patients, their families, and the healthcare system. We describe the experimental implementation of a collaborative, stepped-care model for the treatment of late-life depression (GermanIMPACT trial) in the German primary care context. GermanIMPACT was developed as an adaptation of a successful and widely used American model. The aim of the study is to evaluate the model’s applicability to the German primary care setting and its cost-effectiveness.

Methods/Design: The study will be conducted …

Shared Neural Circuits: The Connection Between Social And Physical Pain, Laura A. Andrews, Theresa E. Didonato

Modern Psychological Studies

Interpersonal rejection, exclusion, and loss are known to produce painful feelings (Eisenberger, Lieberman, & Williams, 2003), but little is know about the neural network underlying this type of pain. Recent evidence suggests this social pain may have important neural connections with physical pain (Eisenberger et al., 2003). The current literature review explores the connection between social pain and physical pain in neural activity, individual differences (e.g., pain sensitivity), situation appraisal, social support, and pain reducers (e.g., acetaminophen). The review examines the overlapping pain system as an evolutionary adaptation necessary for survival (MacDonald & Leary, 2005). Authentic experiences of social rejection …

De Novo Assembly Of The Common Marmoset Transcriptome From Nextgen Mrna Sequences, Mnirnal D. Maudhoo, Dongren Ren, Julien S. Gradnigo, Robert M. Gibbs, Austin C. Lubker, Etsuko N. Moriyama, Jeffrey French, Robert B. Norgren

Psychology Faculty Publications

Background: Nonhuman primates are important for both biomedical studies and understanding human evolution. Although research in these areas has mostly focused on Old World primates, such as the rhesus macaque, the common marmoset (Callithrix jacchus), a New World primate, offers important advantages in comparison to other primates, such as an accelerated lifespan. To conduct Next Generation expression studies or to study primate evolution, a high quality annotation of the marmoset genome is required. The availability of marmoset transcriptome data from five tissues, including both raw sequences and assembled transcripts, will aid in the annotation of the newly …

Bullying: Bullies, Victims, And Witnesses, Loyd White, Frank Hammonds, Karena T. Valkyrie

Modern Psychological Studies

This study examines bullying by focusing on bullies, victims, and witnesses. In an effort to examine long-term correlates of bullying, we asked university students about their experiences with bullying in middle school. We administered a 65 question survey to 191 college students from several university campuses. The survey was made up of the Handling Bullying Questionnaire (Bauman, Rigby & Hoppa, 2008), the Bullying Prevalence Questionnaire (Rigby & Slee, 2003), the Revised Pro-Victim Scale (Rigby, 1997), and 13 researcher created questions which dealt with the participants' experiences with bullying. We hypothesized that rates of bullying would be high and that the …

Female Mating Adaptations: Salient Features And The Influence Of Fertility Status, Katherine Melton

Modern Psychological Studies

Modern human beings share the adaptive mating strategies of their ancestral predecessors, even though the adaptive environment is a relic of the past. Due to the large parental investment mammalian females must contribute in order to reproduce, women face unique challenges in their quest for reproductive fitness. This review endeavors to address behavioral, strategic, and perceptual shifts in female mating adaptations within the context of the menstrual cycle in order to yield a greater understanding of modern women and the evolutionary basis for behavior.

Physiological Arousal Response To Differing Musical Genres, Ericka Kelley, Gabrielle Andrick, Fayelin Benzenbower, Marlene Devia

Modern Psychological Studies

Music is a complex medium that has social, psychological, and physiological implications. Music elicits early emotional responses (arousal) in the sympathetic nervous system, that later become consciously recognized emotions. We investigated how music genre effects physiological arousal by measuring participant skin conductance level (SCL). Physiological responses of 19 participants (3 male, mean age 23 years) were recorded by way of the iWorx 214 Psychophysiology Teaching Kit. The stimuli were four different genres of music: classical, Dubstep, Celtic, and big band (swing). Stimuli were presented to participants in one of four counterbalanced blocks. Participants' highest SCL matched their reported genre preference …

The Measurement Of Attitudes Toward Abortion, Michael G. Taylor, George I. Whitehead

Modern Psychological Studies

Attitudes towards abortion have been a focal point within politics and religion for many years. Many methods have been created to test these attitudes. For example, Hess and Rueb created a 13-item scale and demonstrated its validity. However, this scale has several potential shortcomings. The developers did not report the reliability of the scale and its factor structure. Further, this scale includes a neutral point and legal language. One of the purposes of the present study was to develop a 12-item scale to address these issues. The present study compares and contrasts these two scales. Psychology student's participated in this …

Recovery Is Developmental: An Exploration Of Eriksonian Psychosocial Theory Adapted To Eating Disorder Recovery, Ashley Fee

Modern Psychological Studies

This qualitative study investigated women's experiences of recovery from an eating disorder using an adaptation of Erikson's stage theory of recovery from mental illness. Five female participants, ages 20-40 years old and who identified as having an eating disorder and going through some form of treatment, were interviewed regarding their development, experience, and recovery from an eating disorder after completing the EAT-26 survey. Participants' responses were analyzed using open, axial, and selective coding. Three influences within the recovery process emerged through the analysis: personal (self), transitional, and interpersonal (social). The analysis suggests that an adaptation of Erikson 's developmental theory …

Terror Management Theory: A Theoretical Perspective On Orgination, Maintenance, And Research, Robert B. Arrowood, J. Brian Pope

Modern Psychological Studies

Research suggests that humans engage in several worldview defense mechanisms to shield against the terror associated with an awareness of mortality (Greenberg, Pyszczynski, & Solomon, 1986). To mitigate anxiety, people strongly adhere to their cultural worldviews that allow them to boost their self-esteem. This self-esteem fosters a sense of immortality because the world is considered a 'just" place that will not harm someone that is living in adherence to cultural guidelines (Rosenblatt, Greenberg, Solomon, Pyszczynski, & Lyon, 1989). This paper provides a theoretical background for Terror Management Theory including its philosophical origination, the primary tenets of the theory, and the …

Cognitive Function In The Alcohol Addiction Treatment Population, Suranee Abeyesinhe

Loma Linda University Electronic Theses, Dissertations & Projects

Chronic alcohol abuse has been linked to several cognitive deficits, such as problems with spatial processing, decreased executive functioning, impaired verbal fluency, poor working memory, response inhibition, and social problems such as aggression and social deviance. In order for patients to benefit from treatment, they must be able to utilize multiple cognitive functions. Research has shown that patients suffering from cognitive impairments are much more likely to drop out of treatment early, thereby lending them to higher relapse rates. This study aimed to identify cognitive deficits present in the alcohol addiction treatment population, demographic factors associated with higher levels of …

Fibromyalgia And Rheumatoid Arthritis: The Relationship Between Pain, Depression, And Family Health, Macey Wolfe

Loma Linda University Electronic Theses, Dissertations & Projects

Past research suggests that there is a positive relationship between pain and depression in those with fibromyalgia and rheumatoid arthritis, and negative relationship between depression and family health. However, these relationships have not been examined together using hierarchical linear modeling. Participants were 90 patients with either a fibromyalgia or rheumatoid arthritis diagnosis. A series of questionnaires were used to measure depression, pain, and family health. Using a path analysis it was determined that pain was significantly associated with depression, such that as pain increased by one standard deviation depression increased by .48 standard deviations (β = .48, p < .05). Depression was also significantly associated with family health as depression increased by one standard deviation, family health decreased by .23 standard deviations (β = -.23, p < .05). The relationship between all three of these variables, pain, depression and family health, suggests social support should be considered a target of therapy and services as soon as clients experiencing pain are seen by mental health or health professionals as a proactive attempt to stave off more negative consequences of the pain experienced in this patient group.

Changes In Emotion Drive Perceptual Level Shifts: Global Vs. Local Processing, Seda Terzyan

Loma Linda University Electronic Theses, Dissertations & Projects

Different emotional states have been implicated in bringing about specific changes in attention, with positive emotions globalizing attention and negative emotions localizing attention (Fredrickson, 2004). Biases in attentional processes have been associated with the development and maintenance of emotional disorders, anxiety being the most common. Previous studies have shown that anxious individuals present with a bias toward negative information and more readily employ localized attentional processes (Macleod, 2002). This finding demonstrated a link between perceptual levels of attention with higher order conceptual attention, which in turn influences emotional states. Many researchers have explored this relationship, including Fredrickson (2004), who developed …
