Language Development Among Preschool Age Children Born Prematurely, Brittany Nicole Peters

Wayne State University Theses

Premature birth has been shown to be associated with various deficits in neuropsychological functioning during early childhood; however, few studies have attempted to understand the variables that contribute to variability in performance among children born prematurely. The purpose of the current study was to investigate the relationships between specific perinatal factors and language and cognitive outcome measures in a group of preschool-aged children born prematurely (N=47). As predicted, there were significant relationships between sex and specific outcome measures, with boys performing more poorly than girls; however, contrary to hypotheses, significant relationships failed to be found between outcome measures and both …

Antidepressant Medications And Cognitive Functioning In Major Depressive Disorder, Rachel Kay

Wayne State University Theses

Individuals with Major Depressive Disorder (MDD) frequently experience cognitive decrements in addition to mood impairments. Ironically, antidepressant medications used to treat depression may have adverse effects on cognitive functioning. It is imperative to understand the relative cognitive costs of antidepressants when considering the treatment of MDD patients. Furthermore, observational studies of depression are challenged by problems of systematically confounded variables. Researchers are often faced with difficulties in managing this issue and opt to either ignore the problem, alter their sample, or use inappropriate statistical methods (e.g., Analysis of Covariance) due to a limited understanding of acceptable solutions. It is important …

How Mean Is The Mean?, Craig P. Speelman, Marek Mcgann

Research outputs 2013

In this paper we voice concerns about the uncritical manner in which the mean is often used as a summary statistic in psychological research. We identify a number of implicit assumptions underlying the use of the mean and argue that the fragility of these assumptions should be more carefully considered. We examine some of the ways in which the potential violation of these assumptions can lead us into significant theoretical and methodological error. Illustrations of alternative models of research already extant within Psychology are used to explore methods of research less mean-dependent and suggest that a critical assessment of the …

Source Memory And Generation Effects In Parkinson's Disease, Lynn Elizabeth Oelke

USF Tampa Graduate Theses and Dissertations

The primary aim of this study was to investigate source memory performance in individuals diagnosed with Parkinson's disease (PD). The secondary goal was to explore how memory was impacted when subjects were asked to generate responses during encoding. Fifty idiopathic PD patients and fifty healthy control subjects completed a task measuring item memory and source memory which also included a generation manipulation. Relative to controls, PD patients exhibited deficits in source memory but not item memory. Both groups demonstrated enhanced memory performance in the generative condition of the item memory task. The PD group displayed a marginally significant trend toward …

Effects Of Construal Level On The Reliance On Affect Versus Substance, Ellen O'Malley

Legacy Theses & Dissertations (2009 - 2024)

The influence of construal level on judgment and decision-making is often seen in consumer research. However, the effect of construal level on preferences for evaluative inputs rather than final products is less explored. Two experiments were conducted to examine whether construal level affects the degree to which individuals rely on either affective or substantive information when making evaluative judgments; specifically, that abstract construals increase reliance on affective information, whereas concrete construals increase reliance on substantive information. Experiment 1 provided evidence for a relative preference for affective versus substantive information when engaged in abstract and concrete construals, respectively. Experiment 2 replicated …

Ambivalence And The Decision Tree, Kirby Farrell

kirby farrell

We are insolubly ambivalent creatures. Traditionally cultures have managed ambivalence by focusing on character and morality in motives. Freudian psychology recognized that cognitive conflict is insoluble and stressed equilibrium and grace in adaptation. Today technology's binary structure is complicating and sometimes superseding the traditional trope of character by organizing cognition around the trope of the decision tree.

The Forgotten Medium: The Impact Of Reading Violent Literature On Aggressive Thoughts, Mckay Robert Stevens

Theses and Dissertations

Media violence in television, film, video games, and music has been linked to increased aggression. Only in recent years have researchers begun to investigate the impact that reading violent literature can have on individuals. The present study exposed individuals to either a violent or nonviolent story and measured aggressive cognitions. No significant effect was found for story type on aggressive cognitions but a gender effect for aggressive word completions was found. Discussion centers on possible differences between media types as well as future suggestions for investigations into violent literature.

Preventing Guilt By Association: Mindfulness And Susceptibility To Evaluative Conditioning, Laura Kiken

Theses and Dissertations

Evaluative conditioning (EC) is a type of attitude formation in which a stimulus is evaluated as positive or negative based on repeated pairings with valenced stimuli. Emerging evidence suggests that individuals differ in susceptibility to EC and these differences may be related to various social and psychological biases. One variable that has been linked with less negative attitude formation, although not using an EC paradigm, is mindfulness. Further, mindfulness is proposed to alter dimensions of elaboration that may underlie EC, particularly conditioning of negative attitudes. Therefore, three studies were conducted to examine whether mindfulness is linked to differential susceptibility to …

It Pays To Cheat: Tactical Deception In A Cephalopod Social Signalling System, Culum Brown, Martin P. Garwood, Jane E. Williamson

Communication Skills Collection

Signals in intraspecific communication should be inherently honest; otherwise the system is prone to collapse. Theory predicts, however, that honest signalling systems are susceptible to invasion by cheats, the extent of which is largely mediated by fear of reprisal. Cuttlefish facultatively change their shape and colour, an ability that evolved to avoid predators and capture prey. Here, we show that this ability is tactically employed by male mourning cuttlefish (Sepia plangon) to mislead conspecifics during courtship in a specific social context amenable to cheating 39 per cent of the time, while it was never employed in other social contexts. Males …

The Evolution Of Conservative Attitudes As A Complement To Cognitive Threat Detection Mechanisms, Russ Clay

Theses and Dissertations

Conservatism reflects a general attitude structure characterized by a preference for traditional social practices and an aversion to uncertainty and threat. Though the social environment undoubtedly plays a role in shaping conservative attitudes, recent studies suggest that trait-level characteristics may contribute to their development as well. The present research investigated trait-level cognitive threat detection ability as a factor which may influence the development and maintenance of conservative social attitudes. A computer simulation indicated that socially conservative attitudes may function as a strategy for increasing the survival rate of an individual with poor threat detection ability living in a relatively dangerous …

Cybercycling For Cognitive Health: Comparing Physical Mental And Combined Exercise, Anna Scribner

Honors Theses

Several meta-analyses of randomized controlled trials (RCT) have shown exercise to improve cognitive function in normal aging, mild cognitive impairment (MCI) and dementia (Colcombe & Kramer, 2003, O’ Leary et al., 2011). Cognitive benefit from mental exercise alone is less definitive. A recent RCT (Anderson-Hanley et al., 2012) found greater benefit from three months of virtual-reality enhanced exercise than physical exercise alone among 79 independent living older adults. The current study aimed to replicate this work. In this study, six seniors that either lived or worked at Schaffer Heights were enrolled in the study. Participants were randomized into one of …

Factors Affecting Talent Development: Differences In Graduate Students Across Domains, Stephanie Hartzell

UNLV Theses, Dissertations, Professional Papers, and Capstones

There is an abundance of literature on young individuals who show early signs of talent and on older individuals who have demonstrated their abilities throughout the years. This research aims to look at those individuals who are in between, that is, graduate students who have the demonstrated potential to achieve within their fields of study. This study explored backgrounds of talented individuals in their adolescent period and their current measures of cognitive abilities. A total of 38 graduate students majoring in the areas of art (n= 12), science (n= 12), and education (n= 14) were used as examples of individuals …

Goal Attainment As A Function Of Depressive Status In Women: The Role Of Problem-Solving, Lindsay Brauer

USF Tampa Graduate Theses and Dissertations

Despite the theoretical importance of goal-related deficits in individuals with Major Depressive Disorder (MDD), relatively empirical research has examined goal generation and perceived goal attainment in depression vulnerable individuals. The

current project sought to examine the impact of depressive status on perceived goal attainment in currently depressed, remitted depressed, and never-depressed women. In addition, perceived problem-solving skills, a construct thought to be critical for goal

striving and in goal attainment was also examined. Unexpectedly, no effects of depressive status on perceived goal attainment or overall perceived problem-solving skills were observed. Results did however reveal group differences in perceived control in …

Tool Use In Fishes, Culum Brown

Sentience Collection

Tool use was once considered the sole domain of humans. Over the last 40 years, however, it has become apparent that tool use may be widespread across the animal kingdom. Pioneering studies in primates have shaped the way we think about tool use in animals, but have also lead to a bias both in terms of our expectations about which animals should be capable of using tools and the working definition of tool use. Here I briefly examine tool use in terrestrial animals and consider the constraints of the current working definition of tool use in fishes. Fishes lack grasping …

Multicultural Experience Enhances Creativity: The When And How, Angela K. Y. Leung, William W. Maddux, Adam D. Galinsky, Chi-Yue Chiu

Ka Yee Angela LEUNG

Many practices aimed at cultivating multicultural competence in educational and organizational settings (e.g., exchange programs, diversity education in college, diversity management at work) assume that multicultural experience fosters creativity. In line with this assumption, the research reported in this article is the first to empirically demonstrate that exposure to multiple cultures in and of itself can enhance creativity. Overall, the authors found that extensiveness of multicultural experiences was positively related to both creative performance (insight learning, remote association, and idea generation) and creativity-supporting cognitive processes (retrieval of unconventional knowledge, recruitment of ideas from unfamiliar cultures for creative idea expansion). Furthermore, …

The Effect Of Spiritualism On The Cognitive Functions On Learning And Memory, Carla Antonieta Farcello

McNair Poster Presentations

Last summer I conducted a pilot study which researched whether better working memory would be documented among an experimental group (individuals who report being spiritual) as compared to the control group (individuals who report being non-spiritual).Total scores showed a significantly higher sense of spiritualism among the spiritual participants vs. the non spiritual participants (p < .001) along with a significant improvement in working memory for spiritual participants vs. non spiritual participants (p = .027). The results of this study documented significantly better performance on a task measuring emotional learning and memory among individuals who reported being spiritual as opposed to individuals who reported being non-spiritual. These findings build on prior studies suggesting the effect of positive emotions on broadening cognitive processes (Strauss & Allen, 2003).

My current study is building on what my prior findings have suggested and studies the effect of spiritualism on the cognitive functions of learning and memory. In addition to the Daily Spiritual Experiences Scale (DSES) used in the pilot study, I am including the Spirituality Index …

Time-Of-Day Effects On Younger And Older Adult Executive Functioning, Carly E. Violand

ETD Archive

The most recent time-of-day (TOD) body of research has explored how TOD effects can influence certain cognitive domains such as semantic memory, episodic memory, processing speed, and executive functioning (Allen et al., 2008). Research by Horne and Ostberg (1976) has shown how differences in age can be associated with a preference for a certain TOD (i.e., morning or afternoon). Seventy-five percent of adults 65 years or older tend to prefer the morning, whereas fewer than 10 of younger adults tend to prefer the afternoon (Horne & Ostberg, 1976 West et al., 2002). Research by Allen and colleagues (2008) has shown …

The Impact Of Sleep Quality On Cognitive Functioning In Parkinson's Disease, Karina Stavitsky, Sandra Neargarder, Yelena Bogdanova, Patrick Mcnamara, Alice Cronin-Golomb

Psychology Faculty Publications

In healthy individuals and those with insomnia, poor sleep quality is associated with decrements in performance on tests of cognition, especially executive function. Sleep disturbances and cognitive deficits are both prevalent in Parkinson's disease (PD). Sleep problems occur in over 75% of patients, with sleep fragmentation and decreased sleep efficiency being the most common sleep complaints, but their relation to cognition is unknown. We examined the association between sleep quality and cognition in PD. In 35 non-demented individuals with PD and 18 normal control adults (NC), sleep was measured using 24-hr wrist actigraphy over 7 days. Cognitive domains tested included …

The Influence Of Positive And Negative Couple Rituals On Satisfaction, Commitment, And Dyadic Adjustment, Timetra Marie Hampton

Theses Digitization Project

The current study predicted that positive couple rituals would be positively associated with relationship satisfaction, commitment, and dyadic adjustment, whereas negative couple rituals were expected to exhibit a negative association with these outcome variables. Data for this study were collected online in 2009. Participants included undergraduate students from California State University San Bernardino (CSUSB), the University of Georgia (UGA), and the University of Connecticut (UNCONN).

How Selective Is Social Learning In Dolphins?, Stan A. Kuczaj Ii, Deirdre Yeater, Lauren Highfill

Psychology Faculty Publications

Social learning is an important aspect of dolphin social life and dolphin behavioral development. In addition to vocal social learning, dolphins discover behaviors for foraging, play, and social interactions by observing other members of their social group. But dolphins neither indiscriminately observe nor mindlessly mimic other dolphins. To the contrary, dolphin calves are quite selective in their choices of who to observe and/or imitate. Calves are most likely to learn foraging behaviors from their mothers, but they are more likely to watch and reproduce the play behaviors of other calves than the play behaviors of adult dolphins (including their mothers). …

Constant Enough: On The Kinds Of Perceptual Constancy Worth Having, Frank H. Durgin, Anna Jane Ruff , '09, Robert Calverley Russell , '08

Psychology Faculty Works

This chapter argues that whereas perceptual experience is underconstant in one sense, it is virtually constant insofar as it is functionally stable and predictable. The possibility of distinguishing perception and cognition is explored in experiments on the perception of surface orientation. These experiments are related to the study of self-motion perception and space perception. An experiment comparing monocular and binocular perception of hills revealed perceptual differences, between-subjects, that were masked in within-subject comparisons by metacognitive strategies. A second experiment found that participants wearing heavy backpacks gave (cognitively) elevated slope estimates only because of experimental demands not physical ones. Perceptual experience …

The Impact Of A Video Game Intervention On The Cognitive Functioning, Self-Efficacy, Self-Esteem, And Video Game Attitudes Of Older Adults, Giovanni W. Sosa

CGU Theses & Dissertations

While a well-established body of empirical work indicates that engaging in mentally stimulating activities is linked to positive physical and mental health outcomes, relatively few studies have specifically examined the impact that video game training can have on cognitive functioning and well-being. Given the substantial implications that such work has for an ever-growing older adult population, this area of research has begun to pique the interest of researchers world-wide. The present study employed an experimental paradigm to explore the impact of a Nintendo DS video game, Brain Age, on the cognitive functioning, self-efficacy, self-esteem, and video game attitudes of …

Physiological Reactions To Uncanny Stimuli: Substantiation Of Self-Assessment And Individual Perception, Tatiana Ballion

Electronic Theses and Dissertations

There is abundant anecdotal evidence substantiating Mori’s initial observation of the "uncanny valley", a point at which human response to non-human entities drops sharply with respect to comfort (Mori, 1970), and the construct itself has a long-standing history in both Robotics and Psychology. Currently, many fields such as design, training, entertainment, and education make use of heuristic approaches to accommodate the anticipated needs of the user/consumer/audience in certain important aspects. This is due to the lack of empirical substantiation or, in some cases, the impossibility of rigorous quantification; one such area is with respect to the user’s experience of uncanniness, …

Cognitive Profiles And The Impact Of Medication On Children With Attention Deficit Hyperactivity Disorder, Lucy J. Wimpenny

PCOM Psychology Dissertations

Attention Deficit Hyperactivity Disorder (ADHD) is one of the most frequently diagnosed disorders in children and adolescents. Individuals with ADHD often display behavioral symptoms, including inattention and/or impulsivity, which can also lead to struggles in the school setting. Current research has suggested that deficits in processing speed and working memory are common in individuals diagnosed with ADHD and are often seen on measures of cognitive ability. Positive outcomes have been associated with the use of psychostimulant medication to treat the symptoms of ADHD, although little research has supported this form of treatment to improve cognitive functioning in individuals diagnosed with …

Visual Memory Improvement In Recognition, Allison Prandl

Theses : Honours

Fluid intelligence and working memory has been improved by training on a visual working memory n-back task (Jaeggi, Buschkuehl, Jonides & Perrig, 2008). The present study investigated whether n-back training can improve visual memory using a test of visual recognition. A sample of 47 participants were trained for 20 days on either the single n-back task (n = 26) or a general knowledge and vocabulary task (n = 21). The results showed that training using the single n-back task did not significantly increase scores on a test of visual recognition when compared with general knowledge and vocabulary training. However, when …

Improving Memory Using N-Back Training, Paul Beavon

Theses : Honours

Investigations into n-back training and near transfer to short-term memory (STM) and working memory (WM) have realised inconsistent results. A significant transfer to STM was reported using dual n-back training (Jaeggi, Buschkuehl, Jonides, & Perrig, 2008). However, the majority of studies have found no significant transfer to WM as operationalised by complex span tasks using either single or dual n-back training. The current study examined the single n-back task and near transfer to STM and WM as operationalised by the Woodcock-Johnson III Tests of Cognitive Abilities (Mather & Woodcock-Johnson, 2001). Forty-seven participants were divided into experimental treatment (n = 26) …

Association Between C-Reactive Protein And Cognitive Deficits In Elderly Men And Women: A Meta-Analysis, Bruce L. Brown, Dawson W. Hedges, Thomas J. Farrer

Faculty Publications

Abstract

Background: Certain risk factors for cognitive decline appear modifiable. A potentially modifiable marker of inflammation, C-reactive protein may be associated with cognitive deficits, although not all studies have found a relationship between C-reactive protein and cognitive ability. Further, few research papers have examined whether gender may affect any association between C-reactive protein and cognitive deficit.

Methods: To better understand the association between C-reactive protein, cognitive deficit, and gender in elderly people, we meta-analyzed cross-sectional studies that reported cognitive ability assessed by the Mini-Mental State Examination or an equivalent measure, C-reactive protein concentrations, and gender.

Results: While we identified no …

Introduction To Special Issue: Dementia And Music, Andrea R. Halpern, Isabelle Peretz, Lola L. Cuddy

Faculty Journal Articles

This special issue follows two previous special issues on music and neurological disorders (April 2008, Volume 23/Issue 4 and April 2010, Volume 25/Issue 4). Like its predecessors, the issue presents studies employing a patient-based approach to music perception, cognition, and emotion. Whereas the earlier issues dealt with acquired and congenital disorders and impairments, the present issue focuses on dementia, primarily on its most common form, Alzheimer's disease (AD).

Visual Attention To Erotic Stimuli In Androphilic Male-To-Female Transsexuals, Sarah A. Akhter

UNLV Theses, Dissertations, Professional Papers, and Capstones

The present study investigated sex differences in visual attention to erotic stimuli by comparing three groups of individuals: heterosexual men, heterosexual women, and androphilic MtF transsexuals. Twenty men, 20 women and 13 MtF transsexuals were shown 10 split-screen slides, each featuring one nude erotic photo of a man shown on half of the screen and one nude erotic photo of a woman shown on the other half of the screen. Eye movements were tracked as participants viewed the slides. All participants were heterosexual (Kinsey 0-1) relative to gender identity, thus erotic targets for natal men were nude women in the …
