Principles In Public Reasoning About Criminal Justice : Victim Vulnerability, Trust, And Offender Status, Dianne R. Mckillop

Theses: Doctorates and Masters

It is popularly assumed that the public is highly punitive toward criminal offenders and that its reasoning about criminal offences is emotionally and morally based. This assumption has been challenged by social scientists who cite influences of news media and methodological flaws in empirical studies as contributing causes. Public sentiment is a basis for law and the increasing responsiveness of legislator to what is perceived to be public opinion on crime means that accurate information on enduring principles in the public's intuitive reasoning about criminal justice is vital. An initial exploratory study (N = 34) presented members of the public …

Possible Levels Of Animal Consciousness With Reference To Grey Parrots (Psittacus Erithacus), Irene M. Pepperberg, Spencer K. Lynn

Sentience Collection

Researchers often study nonhuman abilities by assuming their subjects form representations about perceived stimuli and then process such information; why then would consciousness be required, and, if required, at what level? Arguments about nonhuman consciousness range from claims of levels comparable to humans to refutation of any need to study such phenomena. We suggest that (a) species exhibit different levels attuned to their ecological niches, and (b) animals, within their maximum possible level, exhibit different extents of awareness appropriate to particular situations, much like humans (presumably conscious) who often act without conscious awareness of factors controlling their behavior. We propose …

Spontaneous Discrimination Of Natural Stimuli By Chimpanzees (Pan Troglodytes), David A. Brown, Sarah T. Boysen

Sentience Collection

Six chimpanzees (Pan troglodytes) were presented with pairs of color photographic images of 5 different categories of animals (cat, chimp, gorilla, tiger, fish). The subjects responded to each pair using symbols for "same" and "different." Both within- and between-category discriminations were tested, and all chimpanzees classified the image pairs in accordance with the 5 experimenter-defined categories under conditions of nondifferential reinforcement. Although previous studies have demonstrated identification or discrimination of natural categories by nonhuman animals, subjects were typically differentially reinforced for their responses. The present findings demonstrate that chimpanzees can classify natural objects spontaneously and that such classifications may be …

Animal Minds And Animal Emotions, Marian Stamp Dawkins

Emotion Collection

The possibility of conscious experiences of emotions in non-human animals has been much less explored than that of conscious experiences associated with carrying out complex cognitive tasks. However, no great cognitive powers are needed to feel hunger or pain and it may be that the capacity to feel emotions is widespread in the animal kingdom. Since plants can show surprisingly sophisticated ‘‘choice’’ and ‘‘decision-making’’ mechanisms and yet we would not wish to imply that they are conscious, attribution of emotions to animals has to be done with care. Whether or not an animal possesses anticipatory mechanisms associated with positive and …

Cognitive Inhibition And Impulsivity In Adult Children Of Alcoholics And Controls, Louise A. Weller

Theses and Dissertations

The genetic transmission of a pattern of impairments associated with alcoholism has been supported by research literature (Dawson, Harford, & Grant, 1992; Schuckit, 1986). No single factor appears to cause the development of a substance abuse problem, but a family history of alcoholism may be one predictive factor (Goodwin, 1985). The offspring of alcoholics are more likely to display disinhibited behavior and impulsivity (Pihl, Peterson, & Finn, 1990) and are more likely to develop drinking problems than the general population (Goodwin, 1971). Researchers have found patterns of cognitive deficits (Tartar, Jacob, Bremer, 1989) and neuropsychological differences (Gabriella & Mednick, 1983) …

The Relationships Among The Stimulus Functions And The Clinical Effects Of Methylphenidate In Children Diagnosed With Adhd, Emily K. Macdonald

Masters Theses

Attention deficit hyperactivity disorder (ADHD) is the most commonly diagnosed childhood psychiatric disorder in the United States. Approximately 90% of children receiving pharmacological treatment for ADHD receive the stimulant methylphenidate (MPH). MPH is associated with positive effects across many behavioral domains, yet the mechanisms through which it exerts clinical effects have not been conclusively determined. MPH produces reinforcing and subjective effects, however it is not understood how these functions relate to clinical effects. The present study examined the relationship among several stimulus functions and the clinical effects of MPH. Participants were 5 children (aged 10-14) diagnosed with ADHD who were …

Male Coercive Sexual Behavior As A Function Of Male Resource-Potential And Respondent Gender., Christy D. Wolfe

Electronic Theses and Dissertations

The present study examined whether the resource-potential (RP) of a male dater (i.e., potential financial success and status) and/or respondent gender related to attitudes toward coercive sexual behavior by the male. Participants (59 males and 82 females) read a hypothetical dating scenario in which a heterosexual couple went out for dinner and then returned to the female’s apartment to watch a movie. The RP of the male dater was set at high and low. Following the scenario, rating scales posing increasing levels of coercive sexual behavior (a sexual advance, verbal persuasion, and physical coercion) were presented. The participants rated the …

The Effects Of An Outdoor School Program On 6th-Graders’ Empathy And Attitudes Towards Nature, Carolyn Ann Occhipinti

Dissertations and Theses

Past research in environmental psychology and education has shown that outdoor experiences such as wilderness adventure camps and environmental education programs may result in increases in participants' self-esteem, sense of connectedness to the natural world and environmental awareness. Developmental research has suggested a link between high self-esteem and increased levels of empathy.

The present study was intended to explore possible effects of nature experiences on empathy development, and to add to our understanding of the relationship between people and the natural environment by measuring four aspects of children's subjective experiences: empathy, self-esteem, sense of connectedness to the natural world, and …

Fathering Appraisals As Predictors Of Children's Stability And Positive Faith Attitudes, Leslie Gambill Brost

Doctor of Psychology (PsyD)

Twenty-eight children (15 male, 13 female, mean age 11.36) and their fathers (mean age 43.11), from various communities in the Western United States, participated as dyads. Fathers completed demographic questions, the Short Version Seven Secrets Survey for Fathers (Roid & Can.field, 1994), and selected questions from the New Personal Fathering Profile (Roid & Can.field, 1999). Children completed a revised Short Version Seven Secrets Survey for Fathers and the Francis Scale of Attitude Towards Christianity (Francis, 1989). Fathers and children completed a shortened version of Factor IV: Emotional Stability from the International Personality Item Pool (Goldberg, 1997). Children's fathering appraisals were …

Attentional Processing In Parkinson's Disease: Hyperkinetic And Akinetic Type, Christine Diane Kraus

Loma Linda University Electronic Theses, Dissertations & Projects

Parkinson's disease (P.D.) has long been thought of as a single disorder. Recent research involving neurochemistry, neurophysiology, and detailed analysis of symptoms, have created a basis for questioning the concept that P.D. is a singular disorder. Literature suggests there may be two primary subtypes (with the possibility of others). The two probable subtypes are hyperkinetic, in which tremor is the predominate symptom and akinetic, in which, gait freezing and postural instability predominate.

In both of these pathological manifestations, several investigators have noted cognitive deficits including attention. The differences in symptomotology and neuropathology attributed to these probable subtypes suggest that there …

Human Error And Accident Causation Theories, Frameworks And Analytical Techniques: An Annotated Bibliography, Douglas A. Wiegmann, Aaron M. Rich, Scott A. Shappell

Publications

Over the last several decades, humans have played a progressively more important causal role in aviation accidents as aircraft have become more [complex]. Consequently, a growing number of aviation organizations are tasking their safety personnel with developing safety programs to address the highly complex and often nebulous issue of human error. However, there is generally no “off-the-shelf” or standard approach for addressing human error in aviation. Indeed, recent years have seen a proliferation of human error frameworks and accident investigation schemes to the point where there now appears to be as many human error models as there are people interested …

The Darwin Is In The Details, Douglas T. Kenrick, Norman P. Li

Research Collection School of Social Sciences

Comments on the article by A. H. Eagly and W. Wood which examined the origins of sex differences in human behavior. Eagly and Wood argued that social structural theory can explain the origin of psychological sex differences. The present authors suggest that evolutionary models of sex differences are based on a much broader foundation that Eagly and Wood imply. They note that Eagly and Wood misconstrued previous age preference findings as supporting the "common knowledge" that men prefer younger women. Eagly and Wood also showed that as societies approach gender equality in resource access, some sex differences in mate preferences …

An Analysis Of The Influence Of Age And Ionizing Radiation On Cognitive Performance, Elizabeth L. Gerhardt

Master's Theses - Daytona Beach

This thesis was designed to study whether age has a significant effect on cognitive test results among persons exposed to ionizing radiation. The data for this investigation came from the fourth year of a 1995-98 longitudinal study of subjects exposed to radiation from the 1986 Chernobyl, Ukraine, nuclear power plant accident. Accuracy and efficiency scores from four cognitive tests taken by 84 Ukrainian volunteers were divided into two age groups and three radiation dosage groups for analysis. The results of this study found that decrements in human performance on tasks involving spatial processing increase with age in persons who have …

Alterations In Neurogenesis Following The Transition From Virgin To Maternal/Lactating Female, Elizabeth Amory

Master's Theses

The hippocampus displays hormone induced plasticity during estrus. Pregnancy, which exposes a female to a significantly longer duration of elevated estrogen and progesterone, results in even greater changes in neurons in the CA1 region of the hippocampus, with late-pregnant and lactating females displaying a significantly higher concentration of apical dendritic spines. Hippocampal astrocytes were increased in number and showed more and thicker processes in late-pregnant and lactating females. Such anatomical changes may also enhance spatial learning and memory. Changes in reproductive capacity may influence the rate at which new neurons are born, so called neurogenesis. In two experiments, neurogenesis in …

A Preliminary Investigation Of The Acceptability And Effectiveness Of Computer-Based Adjunctive Parent Training For Child Noncompliance, Dwayne M. Munneke

Dissertations

Noncompliance with parent requests is a commonly reported behavior problem for clinic-based child referrals. Parent skills training has been empirically demonstrated as an effective treatment for helping parents increase positive child behaviors and decrease negative behaviors. Unfortunately, many therapists and agencies are unable to implement parent-training programs due to limited therapist training, limited economic resources, or long waiting lists.

Adjunctive, computer-based, treatment programs have become increasingly popular in both research and clinical settings for facilitating psychological assessment and intervention. This project involved the development and preliminary investigation of the effectiveness and acceptability of a computer-based program designed to supplement therapist-delivered …

A Resident Teacher Program: Perceptions Of Those Involved, Sara Beth Vinje Triggs

Theses and Dissertations

The purpose of this study was to describe and understand the experience of master's students in an elementary education resident teacher program The experience of the resident teachers was generally defined as how resident teachers made meaning of a resident teacher program through the perceptions of the resident teachers themselves. The resident teachers' perceptions and experiences were studied from January 1999 through the completion of their teaching experience in May 1999.

Qualitative research methods were used in this phenomenological study, including a brief period of observation, analysis of mentor/resident teacher communications journals, and interviews with participants in the Resident Teacher …

Primate Numerical Competence: Contributions Toward Understanding Nonhuman Cognition, Sarah T. Boysen, Karen I. Hallberg

Sentience Collection

Nonhuman primates represent the most significant extant species for comparative studies of cognition, including such complex phenomena as numerical competence, among others. Studies of numerical skills in monkeys and apes have a long, though somewhat sparse history, although questions for current empirical studies remain of great interest to several fields, including comparative, developmental, and cognitive psychology; anthropology; ethology; and philosophy, to name a few. In addition to demonstrated similarities in complex information processing, empirical studies of a variety of potential cognitive limitations or constraints have provided insights into similarities and differences across the primate order, and continue to offer theoretical …

Group And Individual Treatment Of Compulsive Hoarding: A Pilot Study, Gail Steketee, Randy O. Frost, Jeff Wincze, Kamala A.I. Greene, Heidi Douglass

Psychology: Faculty Publications

Treatment of compulsive hoarding has rarely been described in the literature, apart from standard treatments for obsessive compulsive disorder of which hoarding is thought to be a subset. This paper presents preliminary findings from seven patients treated with cognitive and behavioral interventions derived from Frost and Hartl's (1996) theoretical model of hoarding. Six clients attended 15 group treatment sessions over 20 weeks plus individual home treatment sessions and one client received 20 weekly-sessions of individual treatment only. After 20 weeks, treatment resulted in noticeable improvement in several hoarding symptoms for five of the seven patients, especially reduction in excessive acquisition …

The Political Personalities Of 2000 U.S. Presidential Candidates George W. Bush And Al Gore, Aubrey Immelman

Psychology Faculty Publications

This paper presents the results of indirect psychodiagnostic assessments of the political personalities of Texas governor George W. Bush and U.S. vice president Al Gore, putative Republican and Democratic nominees in the U.S. presidential election of 2000, from the conceptual perspective of Theodore Millon.

Information concerning George W. Bush and Al Gore was collected from published biographical and autobiographical accounts and political reports in the print media, and synthesized into personality profiles using the second edition of the Millon Inventory of Diagnostic Criteria (MIDC), which yields 34 normal and maladaptive personality classifications congruent with Axis II of DSM–IV.

Law And The Biology Of Rape: Reflections On Transitions, Owen D. Jones

Vanderbilt Law School Faculty Publications

This Article serves is a sequel to a previous Article: Sex, Culture, and the Biology of Rape: Toward Explanation and Prevention, 87 Cal. L. Rev. 827 (1999). Part I briefly considers the threshold question: why consider the behavioral biology of sexual aggression at all? Part II proposes that the first step in transitioning to a more accurate and more useful model of rape behavior is to avoid a number of common definitional ambiguities that plague most rape discussions. Because those ambiguities are particularly likely to foster misunderstandings about biobehavioral perspectives, Part II also clarifies the scope of what biobehavioral theories …

Mixing At Young Ages Reduces Fighting In Unacquainted Domestic Pigs, Anton D. Pitts, Daniel M. Weary, Edmond A. Pajor, David Fraser

Agonistic Behavior Collection

Under normal farming practices, piglets from different litters are often mixed around the time of weaning, and a high incidence of fighting and minor injuries often occur. The aim of this experiment was to determine the effect of age on the incidence of fighting in piglets mixed before weaning, at different ages between 5 and 26 days. We found no significant relationship between age and the likelihood that a pair of piglets would fight during the first 75 min after mixing. However, the duration of the first fight observed increased from 101±38 s at 5 days to 621±278 s at …

Vocabulary Growth In Late Talkers: Lexical Development From 2;0 To 3;0, Leslie Rescorla, Jennifer Mirak, Leher Singh

Psychology Faculty Research and Scholarship

Vocabulary growth from 2;0 to 3;0 was studied in 28 late talkers using expressive vocabulary inventories reported bimonthly on the Language Development Survey (LDS). Group milestones were 18 words at 2;0, 89 words at 2;6, and 195 words at 3;0. A sub-group of 11 children (Group I) showed a rapid vocabulary spurt between 2;2 and 2;8, reached the 150-180 word mark by 2;6, and attained the LDS ceiling of about 300 words by 2;10. In contrast, the 17 children in Group 2 still had a mean vocabulary of fewer than 30 words at 2;6, had less of a vocabulary spurt …

Assessment Of Methylphenidate Sensitization Using A Two-Lever Drug Discrimination Procedure, Ann Marie Heidema

Masters Theses

The current study examined the effects of methylphenidate (MP) pre-exposure on the acquisition of cocaine discrimination in rats. Sixteen male Sprague-Dawley rats were administered either 10 mg/kg MP or saline for five consecutive days. Following this pre-treatment phase, animals were trained to discriminate 10 mg/kg cocaine-hydrochloride from saline using a two-lever fixed-ratio 20 (FR20) schedule of food reinforcement. Acquisition of cocaine discrimination, as indicated by the number of sessions to criterion, did not differ significantly between the two-pre-treatment groups (MP = 35.5 ± 2.4; SAL = 31.6 ± 2.3). Stimulus generalization tests were conducted with cocaine and methylphenidate using cumulative …

Affective Responses To Television Newscasts: Have You Heard The News?, Jessica Purtan Harrell

This study examined the impact o f television news viewing on affective responses in viewers. Participants watched a 10-minute newscast that contained only negative, only positive, or both negative and positive news stories at either 8:00 a.m. or 6:00 p.m. Negative news viewers showed elevations in anxiety and negative affect, while positive news viewers showed decreases in anxiety and negative affect. Watching a combined newscast resulted in no mood changes. Affective changes caused by watching the news were not maintained 3 hours after viewing, and morning versus evening viewing had no impact on mood responses to that news. While news …

Development Of A Bedside Examination Of Cognition In Multiple Sclerosis (Becims), Gregory Scott Aaen

Loma Linda University Electronic Theses, Dissertations & Projects

Approximately 40% of all patients with multiple sclerosis (MS) exhibit some form of cognitive impairment. Identifying impairment in these patients would be beneficial to the patients and to society. However, it is too costly to refer every MS patient for full neuropsychological testing. Consequently, many attempts have been made to develop screening batteries for use by neurologists. Unfortunately, these batteries are rarely used clinically as all require approximately 20-40 minutes to administer and most require special equipment. Given the time constraints of an office visit it is unrealistic to expect neurologists to administer such tests. The present pilot study is …

The Effects Of Interviewer Self-Monitoring On Male Appearance Discrimination In Employment Decisions, Charles Mcdowell

Masters Theses & Specialist Projects

This research examined the effects of appearance discrimination toward men as regards employment decisions and the extent to which the degree of interviewer selfmonitoring influences these decisions. Past research has indicated that discrimination does indeed occur for women, but no empirical research has been conducted on male discrimination in which hair length has been manipulated. Specifically, length of hair (shoulder length, approximately 1 inch, and balding) was manipulated for potential job applicants. These conditions were examined across different types of jobs (traditionally conservative, neutral, and traditionally liberal). Several hypotheses are offered, with most focused on the concept that those scoring …
