Memory Behaviour Requires Knowledge Structures, Not Memory Stores, Guillermo J. Campitelli

Research outputs 2014 to 2021

Since the inception of cognitive psychology dominant theories of memory behavior have used the storage metaphor. In the multi-store models (e.g., Broadbent, 1958; Atkinson and Shiffrin, 1968; Baddeley and Hitch, 1974) the memory system comprises one or more short-term memory (STM) stores and a long-term memory (LTM) store. These stores are places where information is located for varying periods of time (i.e., seconds in the STM stores, and minutes to lifetime in the LTM store) and they have varying capacity limits: large for the LTM store, very limited for the STM store—4 to 7 items, see Miller (1956), Broadbent (1958), …

Editorial: Neural Implementation Of Expertise, Merim Bilalic, Robert Langner, Guillermo J. Campitelli, Luca Turella, Wolfgang Grodd

Research outputs 2014 to 2021

How the brain enables humans to reach an outstanding level of performance typical of expertise is of great interest to cognitive neuroscience, as demonstrated by the number and diversity of the articles in this Research Topic (RT). The RT presents a collection of 23 articles written by 80 authors on traditional expertise topics such as sport, board games, and music, but also on the expertise aspects of everyday skills, such as language and the perception of faces and objects. Just as the topics in the RT are diverse, so are the neuroimaging techniques employed and the article formats. Here we …

Investigating The Role Of Objective And Subjective Task Complexity On Retirement Investment Plan Earnings Judgments, Natasha Hardy

Dissertations, Master's Theses and Master's Reports

This research addressed the effect of retirement plan task complexity on retirement plan earnings estimates. Past research has shown that increased task complexity results in more decision-making errors as well increased use of heuristics, or rules of thumb, which can result in non-optimal outcomes such as under-saving or disproportionate equity/income balances (Benartzi & Thaler, 2001, 2007; Maynard & Hakel, 1997). This research used two experiments to test whether individuals would judge a retirement investment plan with high task complexity to be more profitable than a plan with low task complexity - a non-normative and potentially costly bias. Experiment 1 used …

An Investigation Of The Increased Reliance On Familiarity In Associative Recognition Of Unitized Compound Word Pairs, Fahad Naveed Ahmad

Theses and Dissertations (Comprehensive)

Unitization refers to when two components are integrated or combined into a single unit. So the whole is more familiar than the parts (Graf & Schacter, 1989). Previous researchers have shown unitization of unrelated word pairs can occur by the use of compound definition. As support, they have found unitization to increase reliance on familiarity in associative recognition. The purpose of this PhD dissertation was to examine the effects of unitization of preexperimental associations on associative recognition. The effects of associative recognition of unitized compound word (CW) pairs can serve as a useful benchmark to compare to that of other …

Javan Gibbon (Hylobates Moloch) Non-Vocal Social Communication And Gesture Use With Conspecifics, Melanie Bell

All Master's Theses

I explored gestures used by captive Javan gibbons (Hylobates moloch) at the Gibbon Conservation Center (Santa Clarita, CA). I hypothesized that a sender gibbon’s gesture modality would vary with the recipient gibbon’s attentional state and the sender would be equally likely to use all modalities (tactile, visual, actions, and facial expressions) when the recipient was attending (facing the sender), but would use more tactile gestures and actions when the recipient was non-attending (oriented away from the sender). I collected data from 10 individuals using all-occurrences sampling and an ethogram to score behaviors from video recordings. In 1,143 interactions, …

The research objectives of this study included: exploring the possible sense of occupational imbalance in an individual’s self-identity, exploring the personal identity of individuals who perceive themselves as artists but work at a different career, and explaining the relationships between art and self-identity including life balance, work ethic, and education. This research was based in an occupational science viewpoint, in that it looked at how occupations help to define life meaning, purpose, and identity. …

An Examination Between High And Low Optimistic Ncaa Division I Student-Athletes' Perceptions Of Preferred Leadership Behavior In Sport: A Qualitative Investigation, Alexander C. Roorda

College of Graduate Studies: Theses & Dissertations

Numerous researchers have examined preferred sport leadership behaviors from both the coach and athlete perspectives (Beam, Serwatka, & Wilson, 2004; Chelladurai, & Carron, 1983; Freakley, Czech, Harris, & Burdette, 2012; Turman, 2013; Weinburg, & Gould, 2010). However, there is limited research in student-athlete personality dispositions and how those might influence student-athlete perceptions of preferred leadership behaviors. The purpose of the present study was to examine views of leadership in light of certain personality dispositions. This research examined the potential influence of optimism (Abramson, et al, 2000) on qualitative descriptions of preferred leadership behaviors using the Revised Leadership Scale for Sport …

Tornado Trouble: How Can Current Tornado Warnings Be Improved?, Jonathan P. Evans

College of Graduate Studies: Theses & Dissertations

There are many unnecessary deaths from tornadoes every year (NOAA.org, 2013). Although there have been great advancements in tornado warning systems (Coleman, Knupp, Spann, Elliot, & Peters, 2010), more changes to systems could be made to motivate people to take action in preparation for tornadoes (Brotzge & Donner, 2013). Protection motivation theory outlines the process by which we assess threats and decide whether or not preventative actions are worth performing. If the threat is perceived as severe enough and the preventative actions are seen as capable of mitigating the threat, the individual is motivated to act (Rogers, 2000). One means …

Judging Dread: A Quantitative Investigation Of Affect, Psychometric Dread And Risk Consequence, Melvyn Griffiths

Theses: Doctorates and Masters

Risk is generally understood as a product of the likelihood and consequence of an event. However, the way in which estimations of consequences are formed is unclear due to the complexities of human perception. In particular, the influence of Affect, defined as positive or negative qualities subjectively assigned to stimuli, may skew risk consequence judgements. Thus a clearer understanding of the role of Affect in risk consequence estimations has significant implications for risk management, risk communication and policy formulation.

In the Psychometric tradition of risk perception, Affect has become almost synonymous with the concept of Dread, despite Dread being measured …

Cognitive Fatigue: Exploring The Relationship Between The Fatigue Effect And Action Video-Game Experience, James Brooks

Theses: Doctorates and Masters

the effects of cognitive fatigue. Despite this, there remain advantages to regularly playing action video games. In Study 1, VGPs were significantly better at multitasking on the MATB-II compared to the NVGPs. Further, VGPs also demonstrated superior multitasking when driving, as they made significantly fewer traffic violations compared to NVGPs when not fatigued. VGPs demonstrated eye-movements similar to those of expert drivers; however, this did not result in any difference in performance between the two groups. There was also some evidence of a positive effect of video game training, although there was no advantage of one training technique over the …

Psychotic Diagnosis And Artist Pathology: Schizophrenic Art’S Influence On The Identification Of The Disorder, Danielle Watson

Honors Projects

The use of artwork created by schizophrenic individuals is unique in its contextual elements, including bizarre imagery, strong border lines, and desexualized features. The uniqueness of schizophrenic art lends itself to the possibility of being identified as such, therefore, opening the possibility for it to be used as a diagnostic tool in the clinical setting. Presently, schizophrenic art is used in art therapy, but is not widely employed in diagnostic practices. The current study aimed to test the possible identification of schizophrenic art in contrast to normal art and no art. Three questionnaires were created and randomly distributed to participants. …

Perceived Depth In Non-Transitive Stereo Displays, Bart Farell, Cherlyn J. Ng

Biomedical and Chemical Engineering - All Scholarship

The separation between the eyes shapes the distribution of binocular disparities and gives a special role to horizontal disparities. However, for one-dimensional stimuli, disparity direction, like motion direction, is linked to stimulus orientation. This makes the perceived depth of one-dimensional stimuli orientation dependent and generally non-veridical. It also allows perceived depth to violate transitivity. Three stimuli, A, B, and C, can be arranged such that A > B (stimulus A is seen as farther than stimulus B when they are presented together) and B > C, yet A ≤ C. This study examines how the visual system handles the depth of A, …

Utilizing Visual Attention And Inclination To Facilitate Brain-Computer Interface Design In An Amyotrophic Lateral Sclerosis Sample, David B. Ryan

Electronic Theses and Dissertations

Individuals who suffer from amyotrophic lateral sclerosis (ALS) have a loss of motor control and possibly the loss of speech. A brain-computer interface (BCI) provides a means for communication through nonmuscular control. Visual BCIs have shown the highest potential when compared to other modalities; nonetheless, visual attention concepts are largely ignored during the development of BCI paradigms. Additionally, individual performance differences and personal preference are not considered in paradigm development. The traditional method to discover the best paradigm for the individual user is trial and error. Visual attention research and personal preference provide the building blocks and guidelines to develop …

The Effect Of Grapes In Mice With Alzheimer's Disease And Brain Injury, Nikita Mistry

Loma Linda University Electronic Theses, Dissertations & Projects

Alzheimer’s disease (AD) is a progressive neurodegenerative disorder resulting in cognitive and memory deficits and deposits of amyloid beta (Aβ) in the cortex and hippocampus are thought to be significant contributors to the disease process. Increasing evidence suggests that foods rich in polyphenols, such as pomegranates and grapes, may have neuroprotective effects in both rodents and humans. Our previous research has shown that a pomegranate-enriched diet decreased Aβ plaque load and improved behavior in Tg2576 mice. In this study, we determined whether a grape-enriched diet altered Aβ neuropathology and TBI in PSAPP mice. Mice received either craniotomy or a moderate …

Does Video Game Use Exacerbate The Relation Between Neurophysiological Deficits And Adhd Symptoms In Children And Adolescents?, James Kenneth Goodlad Iii

Dissertations

Attention-deficit/hyperactivity disorder (ADHD) is diagnosed based on behavioral symptoms but is thought to have a significant heritable neurological basis, and several brain structures have been implicated. Recent research has focused on the role of environmental factors that may influence the behavioral expression of inattention and hyperactivity-impulsivity in children and teens, particularly when a biological predisposition exists. This study sought to broaden the literature base by examining the extent to which one environmental factor—video game use—moderated the relation between neuropsychological deficits in attention and inhibition and the behavioral symptoms of ADHD. It was hypothesized that gaming frequency and duration as well …

The case study enabled the researcher to explore the faculties of abstract cognition among students of contrasting skills and abilities in playing chess. The study also allowed for the consideration of potential visual-spatial, logical, academic, social competency and life benefits of chess play. Through analysis of interviews, chess simulations, blindfold chess play, and narration of chess lines and sequences, the investigator was able to extract meaning and code schemata into a holistic understanding of the phenomenon of …

Change Detection In Rhesus Monkeys And Humans, Deepna T. Devkar, Deepna T. Devkar

Dissertations and Theses (Open Access)

Visual working memory (VWM) is the temporary retention of visual information and a key component of cognitive processing. The classical paradigm for studying VWM and its encoding limitations has been change detection. Early work focused on how many items could be stored in VWM, leading to the popular theory that humans could remember no more than 4±1 items. More recently, proposals have suggested that VWM is a noisy, continuous resource distributed across virtually all items in the visual field, resulting in diminished memory quality rather than limited quantity. This debate about the nature of VWM has predominantly been studied with …
