(2020) A Comunidade Da Infância, David Kennedy Jan 2020

(2020) A Comunidade Da Infância, David Kennedy

Collected Papers of David Kennedy

Este livro, A comunidade da infância, é uma forma encontrada para assegurar a presença de David Kennedy entre nós, que tanto o admiramos. Entretanto, resta algo que não se sabe dizer sobre David Kennedy. Como algo que escapa, que foge ao domínio da escrita. David parece nos alertar para algo que permanece infantilmente sem palavra na linguagem. David não se apresenta de imediato. Sua escrita, em voltas, por aproximações e distanciamentos, revela conhecimentos e saberes acerca da infância para tocar aquilo que infantilmente deixou de ser enunciado e escapa à apreensão adulta dos dizeres acadêmicos. Depois de afastar-se do que …


Separating Rope Strands: An Unraveling Of Shame In Gay Men, Chad Allen Lazzari Jan 2020

Separating Rope Strands: An Unraveling Of Shame In Gay Men, Chad Allen Lazzari

Antioch University Dissertations & Theses

This theoretical dissertation uses self psychology, Lacanian theory, and neuropsychoanalysis to explore shame in gay men and formulate an integrative understanding for how this master affect effects self and psyche for same-sex attracted men. Brief introductions to the theories used are provided with links to existing scholarship that informs theoretical leanings. A scholarly case is made for the significance of understanding the origin and lifecycle of shame, as well the importance of differentiating between early relational trauma shame (understood as an “inside out” experience), and a later, socially informed “outside in” experience. An argument is made for how shame “attaches” …


Age-Differential Relationships Among Dopamine D1 Binding Potential, Fusiform Bold Signal, And Face-Recognition Performance, Monroe P. Turner, Håkan Fischer, Dinesh K. Sivakolundu, Nicholas A. Hubbard, Yuguang Zhao, Bart Rypma, Lars Backman Jan 2020

Age-Differential Relationships Among Dopamine D1 Binding Potential, Fusiform Bold Signal, And Face-Recognition Performance, Monroe P. Turner, Håkan Fischer, Dinesh K. Sivakolundu, Nicholas A. Hubbard, Yuguang Zhao, Bart Rypma, Lars Backman

Department of Psychology: Faculty Publications

Facial recognition ability declines in adult aging, but the neural basis for this decline remains unknown. Cortical areas involved in face recognition exhibit lower dopamine (DA) receptor availability and lower blood-oxygen-level-dependent (BOLD) signal during task performance with advancing adult age. We hypothesized that changes in the relationship between these two neural systems are related to age differences in face-recognition ability. To test this hypothesis, we leveraged positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) to measure D1 receptor binding potential (BPND) and BOLD signal during facerecognition performance. Twenty younger and 20 older participants performed a face-recognition task during …


Expressions Of Sexual Deviance In Black Serial Killers, Lucia J. Weatherall Jan 2020

Expressions Of Sexual Deviance In Black Serial Killers, Lucia J. Weatherall

Walden Dissertations and Doctoral Studies

The number of Black serial killers (BSKs) has increased, but empirical studies have not focused on this unique population, including their expressions of sexual deviance. The purpose of this case study was to understand the common socialization experiences and the expressions of sexual deviance in BSKs. Two conceptual frameworks were used to identify the concepts to explore: Bandura’s social learning theory of aggression and Agnew’s general strain theory. Data collected came from archival court and police records in Texas. A content-analysis approach was used to analyze the archival data, organized by criminal background, sexual deviance, familial data, and social development. …


Appealing To Human Intuitions To Reduce Animal Abuse, Yzar S. Wehbe, Todd K. Shackelford Jan 2020

Appealing To Human Intuitions To Reduce Animal Abuse, Yzar S. Wehbe, Todd K. Shackelford

Animal Sentience

Social scientists may be able to find ways to positively affect people’s evolved moral compasses, thereby doing the planet and its inhabitants a great kindness. They could help to shape a constituency that is increasingly opposed to animal abuse in its largest-scale manifestations, factory farming and wet markets. This would, in turn, motivate people to elect ethical leaders who view inaction with regard to animal abuse as a serious moral and medical mistake, if only indirectly due to factory farming’s exacerbation of the threats zoonoses pose to humans.


Impaired Self-Awareness And Brain Injury Outcomes: Comparing The Awareness Questionnaire And Patient Competency Rating Scale In A Post-Acute Rehab Setting, Sitara Shanmugam Jan 2020

Impaired Self-Awareness And Brain Injury Outcomes: Comparing The Awareness Questionnaire And Patient Competency Rating Scale In A Post-Acute Rehab Setting, Sitara Shanmugam

PCOM Psychology Dissertations

The aim of the present study was to examine impaired self-awareness among persons with moderate-to-severe brain injuries, and how it related to functional outcomes in a post-acute rehabilitation setting. Specifically, two self-report measures, the Awareness Questionnaire (AQ) and the Patient Competency Rating Scale (PCRS), were used to assess deficits in awareness by comparing the patients’ ratings with the clinicians’ ratings. In addition, the study also explored impaired self-awareness as it related to poorer community reintegration (as measured by the MPAI-4 Participation Index Subscale). Of the 40 participants in this study, 40% of participants were found to have impaired self-awareness (based …


The Relationship Of Legal History To Mood And Substance Abuse Symptoms Among Homeless Men And Women In A Residential Recovery Program, Lily A. Mkhitarian Jan 2020

The Relationship Of Legal History To Mood And Substance Abuse Symptoms Among Homeless Men And Women In A Residential Recovery Program, Lily A. Mkhitarian

Theses and Dissertations

Homelessness is a devastating experience that impacts hundreds of thousands of individuals in the U.S. each day. It has been widely reported that homeless persons experience higher rates of mental disorder, substance abuse, and physical illness than domiciled individuals. Homelessness is also associated with increased risk of exposure to trauma. In addition, about a quarter of homeless individuals in the U.S. report a history of incarceration. Certainly there are multiple pathways to both homelessness and incarceration. More research is needed on the implications and consequences of having a legal history on homeless persons. The purpose of this archival study was …


Post-Traumatic Stress Symptoms In Sexual And Non-Sexual Trauma: Comparisons On Symptom Severity, Disgust, And Contamination Concerns., Jaime Murtagh Jan 2020

Post-Traumatic Stress Symptoms In Sexual And Non-Sexual Trauma: Comparisons On Symptom Severity, Disgust, And Contamination Concerns., Jaime Murtagh

Electronic Theses and Dissertations

A number of emotions have been identified as contributing to the experience of Post-traumatic Stress Disorder (PTSD) and Obsessive Compulsive Disorder (OCD), including fear and disgust. Given the high rates of comorbidity between PTSD and OCD, research has suggested that disgust may be a likely link between these disorders. The current study examined the relation between contamination disgust, trauma symptom severity, and contamination related-OCD (C-OCD) symptoms in a sample of sexual and non-sexual trauma survivors (N = 206). Specifically, it was proposed that sexual trauma survivors would endorse more severe PTSD symptoms, higher levels of disgust, and more C-OCD symptoms. …


The Effects Of Social Conformity In Human-Robot Interaction, William Volante Jan 2020

The Effects Of Social Conformity In Human-Robot Interaction, William Volante

Electronic Theses and Dissertations, 2020-2023

While previous work has investigated aspects of the robot, the human, and the environment as influential factors in the human-robot relationship, little work has examined the role of social conformity in this relationship. As social conformity has been shown to affect human-human choice, relationships, and trust, there are a-priori reasons to believe that it will play an influential role in human-robot interaction (HRI) scenarios as well. Early research into the influence of social conformity in human-robot interaction (HRI) did not find the effect to be present with robots, however more recent work has adapted the methodological paradigm to find more …


Comparing Human And Machine Learning Classification Of Human Factors In Incident Reports From Aviation, Claas Tido Boesser Jan 2020

Comparing Human And Machine Learning Classification Of Human Factors In Incident Reports From Aviation, Claas Tido Boesser

Electronic Theses and Dissertations, 2020-2023

Incident reporting systems are an integral part of any organization seeking to increase the safety of their operation by gathering data on past events, which can then be used to identify ways of mitigating similar events in the future. In order to analyze trends and common issues with regards to the human element in the system, reports are often classified according to a human factors taxonomy. Lately, machine learning algorithms have become popular tools for automated classification of text; however, performance of such algorithms varies and is dependent on several factors. In supervised machine learning tasks such as text classification, …


Mothers’ And Fathers’ Self-Regulation Capacity, Dysfunctional Attributions And Hostile Parenting During Early Adolescence: A Process-Oriented Approach, Melissa L. Sturge-Apple, Zhi Li, Meredith Martin, Hannah R. Jones-Gordils, Patrick T. Davies Jan 2020

Mothers’ And Fathers’ Self-Regulation Capacity, Dysfunctional Attributions And Hostile Parenting During Early Adolescence: A Process-Oriented Approach, Melissa L. Sturge-Apple, Zhi Li, Meredith Martin, Hannah R. Jones-Gordils, Patrick T. Davies

Department of Educational Psychology: Faculty Publications

The parent-child relationship undergoes substantial reorganization over the transition to adolescence. Navigating this change is a challenge for parents because teens desire more behavioral autonomy as well as input in decision-making processes. Although it has been demonstrated that changes in parental socialization approaches facilitates adolescent adjustment, very little work has been devoted to understanding the underlying mechanisms supporting parents’ abilities to adjust caregiving during this period. Guided by self-regulation models of parenting, the present study examined how parental physiological and cognitive regulatory capacities were associated with hostile and insensitive parent conflict behavior over time. From a process-oriented perspective, we tested …

Developing A Computer-Controlled Treat Dispenser For Canine Operant Conditioning, Walker Arce, Jeffrey R. Stevens Jan 2020

Developing A Computer-Controlled Treat Dispenser For Canine Operant Conditioning, Walker Arce, Jeffrey R. Stevens

Jeffrey Stevens Publications

When performing canine operant conditioning studies, the delivery of the reward can be a limiting factor of the study. While there are a few commercially available options for automatically delivering rewards, they generally require manual input, such as using a remote control, in accordance with the experiment script. This means that human reaction times and transmission distances can cause interruptions to the flow of the experiment. The potential for development of non-supervised conditioning studies is limited by this same factor. To remedy this, we retrofitted an off-the-shelf treat dispenser with new electronics that allow it to be remotely controllable as …


Spatial Memory And Executive Functioning In The Goto-Kakizaki Rat Model Of Diabetes, Lorielle Dietze Jan 2020

Spatial Memory And Executive Functioning In The Goto-Kakizaki Rat Model Of Diabetes, Lorielle Dietze

Theses and Dissertations (Comprehensive)

Type 2 diabetes mellitus is a disease that adversely affects cognitive function in areas extending to memory and executive functioning. The Goto-Kakizaki (GK) rat provides a model of type 2 diabetes that can illustrate the mechanisms by which this disease works. The present study compared hyperglycaemic GK rats and age-matched Wistar rats in the Morris water maze to assess spatial memory, and in a perceptual attentional set-shifting task to assess putative prefrontal-dependent executive functioning. Results showed there was no difference in path length during training trials, however, GK and Wistar rats differed in the path length travelled in the target …


Age, Access, And Sweets-Motivation, Gehan Senthinathan Jan 2020

Age, Access, And Sweets-Motivation, Gehan Senthinathan

Theses and Dissertations (Comprehensive)

Availability can have profound influence on the consumption of foods and drinks. The 2-phase intermittent-continuous protocol (ICP) examines sucrose solution intake in two groups of rats and finds intermittent access significantly increases intake. In Phase I, rats receive intermittent or continuous access to a 4% sucrose solution, and with adults this results in a long-term elevation (a doubling) in the intermittent group. In Phase II, when rats are shifted to common sucrose schedule, this difference is maintained. Adult rats given 16% sucrose in Phase I do not differ in consumption, but in Phase II with 4% sucrose, an unexpressed elevation …


Domestic Violence In Culturally And Linguistically Diverse (Cald) Communities: Perceptions, Therapeutic Approaches And Responses Of Frontline Workers In New South Wales (Nsw), Oluwatoyin A. Dedeigbo Jan 2020

Domestic Violence In Culturally And Linguistically Diverse (Cald) Communities: Perceptions, Therapeutic Approaches And Responses Of Frontline Workers In New South Wales (Nsw), Oluwatoyin A. Dedeigbo

Theses

Domestic violence is a universal public health concern (VicHealth, 2011; World Health Organisation [WHO], 2013). Domestic violence cuts across all countries, regardless of economic, social, cultural or religious differences (Ali et al., 2020; VicHealth, 2011; WHO 2013). Men are often responsible for perpetrating domestic violence against women (Australian Bureau of Statistics [ABS], 2019; Australia Institute of Health and Welfare [AIHW], 2018).

The effects of domestic violence on victims can be serious and long-term; affecting their physical and mental wellbeing, and lingering even after the exposure to violence has ended (Mitchell, 2011). That is, the effect on victims’ mental health is …


A Choice Of Color: Does Lingerie Color Affect Perceived Attractiveness And Evolutionary Fitness?, Samantha Luzietti, T. Joel Wade Jan 2020

A Choice Of Color: Does Lingerie Color Affect Perceived Attractiveness And Evolutionary Fitness?, Samantha Luzietti, T. Joel Wade

Faculty Journal Articles

Prior research examining the effect of color on perceived attractiveness is equivocal. Also, no research has examined how the color of lingerie affects perceptions. This research explored the effect of the color of lingerie that a woman was wearing on individuals’ perceptions of her attractiveness and evolutionary fitness. Three colors of lingerie were used in this study: Black lingerie, Red lingerie, and White lingerie. These images were presented to 72 men and 82 women. Participants rated the woman’s perceived physical attractiveness, sexual attractiveness, trustworthiness, nurturance, masculinity, femininity, dominance, healthiness, enthusiasm, social competence, affectionateness, intelligence, short term mate potential, long term …


Taking A Joke Seriously: When Does Humor Affect Responses To The Slurring Of People With Intellectual Disabilities?, Jennifer Katz, Dimitri Wing-Paul Jan 2020

Taking A Joke Seriously: When Does Humor Affect Responses To The Slurring Of People With Intellectual Disabilities?, Jennifer Katz, Dimitri Wing-Paul

Psychology

The use of humor may affect how bystanders respond to slurs. Undergraduates (N = 192) completed a measure of prejudice towards people with intellectual disabilities and were randomly assigned to read a scenario in which a peer uses a slur either as part of a joke (humor condition) or a statement (control condition). Participants responded to measures of intent to assertively respond and their evaluation of the speaker. Humor inhibited intent to nonverbally disagree and to verbally confront. Bystanders’ own prejudicial attitudes moderated the effects of humor on intent to verbally confront and negative evaluation. In the humor condition, compared …


Free-To-Play? An Examination Of Intrinsic Motivation And Gaming Behaviors In U.S. Female Mobile Gamers, Margot Goldblum Jan 2020

Free-To-Play? An Examination Of Intrinsic Motivation And Gaming Behaviors In U.S. Female Mobile Gamers, Margot Goldblum

Dissertations and Theses

The prevalence of U.S. female gamers has skyrocketed in recent years, largely due to the popularity of mobile games; however, this population is underrepresented in academic research. The present study aimed to close this gap in the literature by focusing on the motivations and behaviors of adult female mobile gamers in the U.S. It also aimed to capture changes in gaming motivation and behavior resulting from the onset of the COVID-19 pandemic. An online sample of 354 American women 18 to 77 years of age (M = 36.79, SD = 12.38) were surveyed about their motivations for mobile gaming, …


Fight, Flight, Or Freezing? Investigating The Immobility Response In Military Veterans, Paige Elizabeth King Jan 2020

Fight, Flight, Or Freezing? Investigating The Immobility Response In Military Veterans, Paige Elizabeth King

UNF Graduate Theses and Dissertations

When the body is faced with threat to life or limb, the autonomic nervous system works to overcome the danger – by either fight, flight, or freezing. While immobility may not appear to be the most logical solution, theories exist that it allows for judgement of the situation and preparation for action. This study investigated the stress response that military veterans, with or without post-traumatic stress disorder (PTSD), demonstrate when shown unpleasant images. Researchers wanted to determine the extent to which veterans would show freezing or immobile responses when under an unpleasant image condition. It was hypothesized that veterans who …


Depressive Rumination And The Mood-As-Input Hypothesis: The Role Of Reverse Catastrophizing, Enrique Cibrian Jan 2020

Depressive Rumination And The Mood-As-Input Hypothesis: The Role Of Reverse Catastrophizing, Enrique Cibrian

UNF Graduate Theses and Dissertations

The mood-as-input hypothesis (MAIH) has been consistently examined in relation to worry, but few studies have examined its role in depressive rumination. Fewer studies have examined congruency effects, such that conditions of mood and perseverative task are congruent (i.e., negative mood and negative preservative task vs. positive mood and positive perseverative task). The current study thus examines the MAIH’s applicability to depressive rumination, includes further investigation on mood congruency, and incorporates a newly constructed positive rumination task to further assess the impact of the valency of a ruminative task. Undergraduate students were randomly assigned to one of eight conditions based …


Sleep, Experiential Avoidance, And Mental Health Symptoms, Anthony Reffi Jan 2020

Sleep, Experiential Avoidance, And Mental Health Symptoms, Anthony Reffi

Graduate Research Theses & Dissertations

The explanatory mechanisms by which sleep disturbances promote psychopathology are not well understood. Given that poor sleep promotes a broad range of negative emotions the next day, sleep disturbances may increase the tendency to identify inner experiences as aversive, thereby promoting experiential avoidance (EA). Though temporarily effective, the frequent and rigid use of EA has been shown to worsen mental health. Therefore, using a seven-day ecological momentary assessment design, this study investigated momentary EA as a mechanism linking subjective sleep quality and quantity with subsequent anxiety and depressive symptoms. Undergraduate participants (N = 86, Mage = 19.72) first completed an …


The Role Of Prediction Error In A Behavioral Memory Reconsolidation Intervention For The Treatment Of Posttraumatic Stress Symptoms: Original Proposal And Update Due To The Covid-19 Global Pandemic, Benjamin Darnell Jan 2020

The Role Of Prediction Error In A Behavioral Memory Reconsolidation Intervention For The Treatment Of Posttraumatic Stress Symptoms: Original Proposal And Update Due To The Covid-19 Global Pandemic, Benjamin Darnell

Graduate Research Theses & Dissertations

A failure to naturally resolve posttraumatic stress symptoms (PTSS) following exposure to a traumatic event is associated with costly and debilitating consequences. Interventions for PTSS are successful for only 40%-70% of patients, and treatment drop-out and symptom relapse are common. Recent research targeting memory reconsolidation mechanisms to augment the memory may provide important information regarding possible paradigms for improving the efficacy of trauma-focused interventions. This research indicates that the use of prediction error during a memory activation cue may result in memory destabilization allowing for the destabilized memory to be updated. Considering that PTSS are inherently memory-dependent, an intervention targeting …


Listener Responses Can Influence The Presentation Of Restricted Interest Topics To Individuals With Asd, Sadaf Fakharzadeh Jan 2020

Listener Responses Can Influence The Presentation Of Restricted Interest Topics To Individuals With Asd, Sadaf Fakharzadeh

University of the Pacific Theses and Dissertations

The behavior of individuals diagnosed with autism spectrum disorder (ASD) can influence caregiver responses that lead to countertherapeutic outcomes. However, there are few experimental evaluations of variables that can cause potentially undesirable interactions between those with ASD and their caregivers. Specifically, little is known about the effects of listener interest on the restricted topics presented by caregivers. We evaluated the influence of listener responses exhibited by a confederate acting as a person with ASD on the topics presented by three undergraduate students who were interested in working with individuals diagnosed with ASD. Each session consisted of a 5-min conversation, during …


Astrocytic Response To Neural Injury Is Larger During Development Than In Adulthood And Is Not Predicated Upon The Presence Of Microglia, Andrew J. Riquier, Suzanne I. Sollars Jan 2020

Astrocytic Response To Neural Injury Is Larger During Development Than In Adulthood And Is Not Predicated Upon The Presence Of Microglia, Andrew J. Riquier, Suzanne I. Sollars

Psychology Faculty Publications

While contributions of microglia and astrocytes are regularly studied in various injury models, how these contributions differ across development remains less clear. We previously demonstrated developmental differences in microglial profiles across development in an injury model of the gustatory system. Nerves of the rat gustatory system have limited capacity to regenerate if injured during neonatal ages but show robust recovery if the injury occurs in adulthood. Using this developmentally disparate model of regenerative capacity, we quantified microglia and astrocytes in the rostral nucleus of the solitary tract (rNTS) following transection of the gustatory chorda tympani nerve (CTX) of neonatal and …


Words Have A Weight: Language As A Source Of Inner Grounding And Flexibility In Abstract Concepts, Guy Dove, Laura Barca, Luca Tummolini, Anna M. Borghi Jan 2020

Words Have A Weight: Language As A Source Of Inner Grounding And Flexibility In Abstract Concepts, Guy Dove, Laura Barca, Luca Tummolini, Anna M. Borghi

Faculty and Staff Scholarship

The role played by language in our cognitive lives is a topic at the centre of contemporary debates in cognitive (neuro)science. In this paper we illustrate and compare two theories that offer embodied explanations of this role: the WAT (Words As social Tools) and the LENS (Language is an Embodied Neuroenhancement and Scaffold) theories. WAT and LENS differ from other current proposals because they connect the impact of the neurologically realized language system on our cognition to the ways in which language shapes our interaction with the physical and social environment. Examining these theories together, their tenets and supporting evidence, …


How Does Eye Movement Desensitization And Reprocessing (Emdr) Work? An Examination Of The Potential Mechanisms Of Action, Sara Forster Jan 2020

How Does Eye Movement Desensitization And Reprocessing (Emdr) Work? An Examination Of The Potential Mechanisms Of Action, Sara Forster

Theses and Dissertations

A mounting body of evidence suggests that Eye Movement Desensitization and Reprocessing therapy (EMDR) is successful in reducing the impact of posttraumatic symptoms. Although the exact mechanisms of action remain unknown, theories from the psychological to the neuroscientific continue to emerge, expand, and evolve. This study will examine four of the most prominent theories to date and weigh the evidence for and against each one. It will also review, compare, and contrast the theories, evaluate the research supporting each one, and propose the most likely explanation for EMDR's success given the state of the research. Neurobiological mechanisms and correlates as …


It Might Not Matter Very Much Whether Insects Are Conscious, Neil Levy Jan 2020

It Might Not Matter Very Much Whether Insects Are Conscious, Neil Levy

Animal Sentience

In common with most other authors, Mikhalevich & Powell assume that phenomenal consciousness is a “precondition” of moral standing. Although the evidence they present makes it much more likely than usually thought that arthropods are phenomenally conscious, scepticism in the face of this evidence remains intellectually respectable. I suggest that we best make progress here by rejecting the notion that phenomenal consciousness is necessary for moral standing. Mental states that may lack phenomenal properties can do a lot of work in grounding moral standing, and there is less room for scepticism about these mental states than about phenomenal consciousness.


Laterality Of Eye Use By Bottlenose (Tursiops Truncatus) And Rough-Toothed (Steno Bredanensis) Dolphins While Viewing Predictable And Unpredictable Stimuli, Malin Lilley, Amber J. De Vere, Deirdre Yeater Jan 2020

Laterality Of Eye Use By Bottlenose (Tursiops Truncatus) And Rough-Toothed (Steno Bredanensis) Dolphins While Viewing Predictable And Unpredictable Stimuli, Malin Lilley, Amber J. De Vere, Deirdre Yeater

Psychology Faculty Publications

Laterality of eye use has been increasingly studied in cetaceans. Research supports that many cetacean species keep prey on the right side while feeding and preferentially view unfamiliar objects with the right eye. In contrast, the left eye has been used more by calves while in close proximity to their mothers. Despite some discrepancies across and within species, laterality of eye use generally indicates functional specialization of brain hemispheres in cetaceans. The present study aimed to examine laterality of eye use in bottlenose dolphins (Tursiops truncatus) and rough-toothed dolphins (Steno bredanensis) under managed care. Subjects were video-recorded through an underwater …


Respiratory Sinus Arrhythmia, Behavioral Inhibition/Activation, And Behavioral Response To A Distressed Infant Simulator In Emerging Adults, Erin R. Mckay Jan 2020

Respiratory Sinus Arrhythmia, Behavioral Inhibition/Activation, And Behavioral Response To A Distressed Infant Simulator In Emerging Adults, Erin R. Mckay

Graduate Research Theses & Dissertations

Caregiver sensitivity and intrusiveness during infancy are predictive of the development of self-regulation, joint-attention, and cognitive ability. However, few studies have examined predictors of caregiver responses to infant distress. Of particular note is vagal tone, specifically respiratory sinus arrhythmia (RSA), a physiological measure of top-down self-regulation. Previous work has identified a relationship between RSA, as well as other measures of caregiver self-regulation, with caregiver sensitivity and intrusiveness. The current study also examined additional predictors of caregiver responsiveness, behavioral inhibition and activation, which was conceptualized as a bottom-up system of self-regulation due to its influence on motivation and personality. It was …
