The Traumatic Stress Response In Child Maltreatment And Resultant Neuropsychological Effects, Kathryn R. Wilson, David J. Hansen, Ming Li

Department of Psychology: Faculty Publications

Child maltreatment is a pervasive problem in our society that has long-term detrimental consequences to the development of the affected child such as future brain growth and functioning. In this paper, we surveyed empirical evidence on the neuropsychological effects of child maltreatment, with a special emphasis on emotional, behavioral, and cognitive process–response difficulties experienced by maltreated children. The alteration of the biochemical stress response system in the brain that changes an individual’s ability to respond efficiently and efficaciously to future stressors is conceptualized as the traumatic stress response. Vulnerable brain regions include the hypothalamic–pituitary–adrenal axis, the amygdala, the hippocampus, and …

Olanzapine And Risperidone Disrupt Conditioned Avoidance Responding By Selectively Weakening Motivational Salience Of Conditioned Stimulus: Further Evidence, Chen Zhang, Yiru Fang, Ming Li

Department of Psychology: Faculty Publications

Suppression of conditioned avoidance response is a preclinical behavioral index of antipsychotic activity. Previous work shows that olanzapine and risperidone disrupt avoidance response elicited by a less salient conditioned stimulus (CS2) to a greater extent than avoidance elicited by a more salient stimulus (CS1), suggesting that antipsychotic drugs may have a weakening action on motivational salience of stimuli. In the present study, we further examined this mechanism of antipsychotic action, focusing on the possible impact of baseline difference of CS1 and CS2 response rates on the avoidance-disruptive effect of olanzapine and risperidone. Rats were first trained to acquire avoidance responding …

Treatment Effects For Common Outcomes Of Child Sexual Abuse: A Current Meta-Analysis, Emily Trask, Kate Walsh, David K. Dilillo

Department of Psychology: Faculty Publications

The present meta-analysis examined the effects of psychosocial treatments at reducing deleterious outcomes of sexual abuse. The meta-analysis included a total of 35 published and unpublished studies written in English, focusing on youth under the age of 18, and evaluating the effectiveness of treatments for the most common negative outcomes of sexual abuse: PTSD symptoms, externalizing problems, and internalizing problems. Results revealed medium effect sizes for PTSD symptoms, externalizing problems, and internalizing problems following treatment for sexual abuse. This study also examined the potential moderating effects of treatment (e.g., modality, duration, and inclusion of caregiver) and participant (e.g., age, gender, …

Multiple “Hits” During Postnatal And Early Adulthood Periods Disrupt The Normal Development Of Sensorimotor Gating Ability In Rats, Jing Chen, Zucheng Wang, Ming Li

Department of Psychology: Faculty Publications

In the present study, we evaluated a multiple-hit animal model of schizophrenia in an attempt to capture the complex interactions among various adverse developmental factors in schizophrenia. Sprague–Dawley rats were assigned to receive either repeated daily 3-h maternal separation for eight days (first “hit”) on postnatal days (PND) 3 to 10, and/or avoidance conditioning for six days (second “hit”) on PND 49–56, and/or repeated phencyclidine treatment (third “hit”, 3.0 mg/kg, sc) immediately after each daily avoidance conditioning. Prepulse inhibition (PPI) of acoustic startle reflex was assessed at late adolescence (PND 41–43) and early adulthood (PND 62–63). The change in %PPI …

Heterogeneity Of Individuals With A History Of Child Sexual Abuse: An Examination Of Children Presenting To Treatment, C. Thresa Yancey, David J. Hansen, Karen Z. Naufel

Department of Psychology: Faculty Publications

The current study examined children and families who presented for treatment through Project SAFE (Sexual Abuse Family Education) following childhood sexual abuse. Pretreatment assessment data were used to develop clusters of participants with significantly differing presentation of symptom outcome following abuse. Four clusters were discovered: (a) a Highly Distressed group, whose members had clinically elevated scores on all self- and parent-report measures; (b) a Problem Behaviors group, whose members had scores within the normal range for self-report measures and elevated scores on all parent-report measures; (c) a Subclinical group, whose participants had scores below the mean and below cutoff scores …

To Google Or Not To Google: Graduate Students’ Use Of The Internet To Access Personal Information About Clients, David K. Dilillo, Emily B. Gale

Department of Psychology: Faculty Publications

The emergence of Internet search and social media sites now permits therapists to obtain a plethora of personal information about their clients online. These behaviors raise a number of ethical issues related to client privacy, self-determination, and informed consent. The purpose of this study is to examine student therapists’ opinions and behaviors in regard to the use these websites to search for information about their clients. A national sample of 854 psychology doctoral students was surveyed in regard to their online activities, attitudes, and frequency of searching for client information online. Results showed that Internet usage is pervasive in this …

Exploring Separable Components Of Institutional Confidence, Joseph A. Hamm, Lisa M. Pytlik Zillig, Alan Tomkins, Mitchel Herian, Brian H. Bornstein, Elizabeth Neeley

Department of Psychology: Faculty Publications

Despite its contemporary and theoretical importance in numerous social scientific disciplines, institutional confidence research is limited by a lack of consensus regarding the distinctions and relationships among related constructs (e.g., trust, confidence, legitimacy, distrust, etc.). This study examined four confidence-related constructs that have been used in studies of trust/confidence in the courts: dispositional trust, trust in institutions, obligation to obey the law, and cynicism. First, the separability of the four constructs was examined by exploratory factor analyses. Relationships among the constructs were also assessed. Next, multiple regression analyses were used to explore each construct’s independent contribution to confidence in the …

Forgetting Constrains The Emergence Of Cooperative Decision Strategies, Jeffrey R. Stevens, Jenny Volstorf, Lael J. Schooler, Jörg Rieskamp

Department of Psychology: Faculty Publications

Theoretical studies of cooperative behavior have focused on decision strategies that depend on a partner’s last choices. The findings from this work assume that players accurately remember past actions. The kind of memory that these strategies employ, however, does not reflect what we know about memory. Here, we show that human memory may not meet the requirements needed to use these strategies. When asked to recall the previous behavior of simulated partners in a cooperative memory task, participants performed poorly, making errors in 10–24% of the trials. Participants made more errors when required to track more partners. We conducted agent-based …

Cognitive-Behavioral Therapy For Immigrants Presenting With Social Anxiety Disorder: Two Case Studies, Brandon J. Weiss, J. Suzanne Singh, Debra Anne Hope

Department of Psychology: Faculty Publications

Cognitive-behavioral therapy (CBT) for the treatment of social anxiety disorder (SAD) has demonstrated efficacy in numerous randomized trials. However, few studies specifically examine the applicability of such treatment for ethnic minority clients. Thus, the purpose of this article is to present two case studies examining the utility of individualized CBT for SAD with two clients who immigrated to the United States, one from Central America and one from China, for whom English was not the primary language. Both clients demonstrated improvement on a semistructured interview and self-report measures. Necessary adaptations were modest, suggesting that therapy could be conducted in a …

Waiting For Grapes: Expectancy And Delayed Gratification In Bonobos, Jeffrey R. Stevens, Alexandra G. Rosati, Sarah R. Heilbronner, Nelly Mühlhoff

Department of Psychology: Faculty Publications

Responses to delayed rewards vary widely across individuals and have important implications for personality and temperament. Animals may avoid delayed rewards because the future is uncertain. Therefore, expectations about receiving a future reward should influence the response to delayed payoffs. Here, we offered bonobos (Pan paniscus) a delayed gratification task in which food accumulated over time. Once subjects chose to consume the reward, food stopped accumulating. We tested their willingness to wait with a reliable and an unreliable experimenter to vary the subjects’ expectations that they would receive the food. Subjects waited less often with the unreliable experimenter …

The Challenges Of Understanding Animal Minds, Jeffrey R. Stevens

Department of Psychology: Faculty Publications

Comparative psychology is by nature an interdisciplinary science that lies at the crossroads of psychology and biology but also draws from other fields in the natural, social, and cognitive sciences. The study of the psychology of animals has been labeled animal cognition, comparative cognition, animal learning, animal psychology, and animal intelligence. Here, comparative psychology is used interchangeably with these terms, encompassing all fields that explore the psychological mechanisms underlying animal behavior, including human behavior.

The primary goal of comparative psychology is to understand the cognitive, emotional, and motivational processes of the animal mind. How do other animals perceive, learn about, …

Relationship Of Personal, Familial, And Abuse-Specific Factors With Outcome Following Childhood Sexual Abuse, C. Thresa Yancey, David J. Hansen

Department of Psychology: Faculty Publications

An examination of the literature on factors related to outcome following child sexual abuse (CSA) revealed many factors that may contribute to symptoms displayed by victims. Factors are divided into three categories: Personal Factors, Familial Factors, and Abuse- Specific Factors. Personal factors are those inherent to the victim, including age, gender, developmental disability, attributions regarding the abuse, and treatment following abuse. Familial factors are defined as those factors associated with other family members. These include parental history of abuse, parental reaction to the disclosure, parental support of the victim, parental mental health, family stress, and treatment following abuse for the …

An Evaluation Of The Applicability Of The Tripartite Constructs To Social Anxiety In Adolescents, Emily R. Anderson, Glen J. Veed, Heidi M. Inderbitzen-Nolan, David J. Hansen

Department of Psychology: Faculty Publications

The current study examined the tripartite model of anxiety and depression in relation to social phobia in a nonclinical sample of adolescents (ages 13-17). Adolescent/parent dyads participated in a semistructured interview and completed self-report measures of the tripartite constructs and social anxiety. Adolescents gave an impromptu speech, and heart rate was monitored. Low positive affect, high negative affect, and high physiological hyperarousal were characteristic of adolescents diagnosed with social phobia; adolescents with elevated social anxiety symptoms who did not meet criteria for social phobia did not evidence low positive affect. Heart rate reactivity during the speech was not significantly correlated …

Grammatical Tense Deficits In Children With Sli And Nonspecific Language Impairment: Relationships With Nonverbal Iq Over Time, Mabel L. Rice

Department of Psychology: Faculty Publications

The relationship between children’s language acquisition and their nonverbal intelligence has a long tradition of scientific inquiry. Current attention focuses on the use of nonverbal IQ level as an exclusionary criterion in the definition of specific language impairment (SLI). Grammatical tense deficits are known as a clinical marker of SLI, but the relationship with nonverbal intelligence below the normal range has not previously been systematically studied. This study documents the levels of grammatical tense acquisition (for third-person singular -s, regular and irregular past tense morphology) in a large, epidemiologically ascertained sample of kindergarten children that comprises 4 groups: …

Stereotype Boost And Stereotype Threat Effects: The Moderating Role Of Ethnic Identification, Brian E. Armenta

Department of Psychology: Faculty Publications

Belonging to a stereotyped social group can affect performance in stereotype-relevant situations, often shifting performance in the direction of the stereotype. This effect occurs similarly for members of positively and negatively stereotyped groups (i.e., stereotype boost and stereotype threat, respectively). This study examined ethnic group identification as a moderator of these effects in the math performance of Asian Americans and Latinos, who are positively and negatively stereotyped in this domain, respectively. Results showed that high ethnically identified Asian Americans performed better and high ethnically identified Latinos performed worse when an ethnicity– ethnic stereotype cue was present. The performance of low …

Department of Psychology: Faculty Publications

This article presents a brief intellectual biography of John and Beatrice Whiting, followed by an examination of five key ideas that they put forward to the fields of psychology and anthropology through their theoretical and empirical writings. These key ideas are (a) the assumption of the psychic unity of humankind, (b) the cultural learning environment, (c) the psychocultural model, (d) the synergistic relationship of the disciplines of psychology and anthropology, and (e) the role of mothers as agents of social change through child-rearing roles as well as through various other ways they guide change in the communities and learning environments …

Development And Initial Psychometric Properties Of The Computer Assisted Maltreatment Inventory (Cami): A Comprehensive Self-Report Measure Of Child Maltreatment History, David K. Dilillo, Sarah A. Hayes-Skelton, Michelle A. Fortier, Andrea R. Perry, Sarah E. Evans, Terri L. Messman Moore, Kate Walsh, Cindy Nash, Angèle Fauchier

Department of Psychology: Faculty Publications

Objectives: The present study reports on the development and initial psychometric properties of the Computer Assisted Maltreatment Inventory (CAMI), a web-based self-report measure of child maltreatment history, including sexual and physical abuse, exposure to interparental violence, psychological abuse, and neglect.

Methods: The CAMI was administered to a geographically diverse sample of college students (N= 1,398). For validation purposes, participants also completed a widely used measure of maltreatment (Childhood Trauma Questionnaire) as well as measures of social desirability. To examine test–retest reliability, a subset of participants (n = 283) completed the CAMI a second time 2–4 weeks after …

Adolescents’ Occupational And Educational Aspirations And Expectations: Links To High School Activities And Adult Educational Attainment, Sarah J. Beal, Lisa J. Crockett

Department of Psychology: Faculty Publications

This longitudinal study explored adolescents’ future-oriented cognitions, current activities, and later educational attainment using data from 317 adolescents (55% female; mean age = 14.98 years, SD = 0.85) followed into early adulthood. Aspirations and expectations regarding work and education showed modest stability from year to year. Exploration of the reciprocal relations between these cognitions and adolescents’ activities supported both unidirectional and bidirectional effects, with different patterns emerging for aspirations and expectations. In multiple regression analyses, future-oriented cognitions predicted adult educational attainment; follow- up analyses indicated that the effect of adolescents’ expectations was partially mediated by participation in extracurricular activities. These …

Punished, Dead Or Alive: Empirical Perspectives On Awarding Punitive Damages Against Deceased Defendants, Timothy R. Robicheaux, Brian H. Bornstein

Department of Psychology: Faculty Publications

Punitive damages are a tool for punishing defendants who engage in reckless and wanton behaviors that cause injury to others. As with criminal punishment, goals of punitive damages include retribution, specific deterrence, and general deterrence. Unlike criminal punishment, however, some courts allow punitive damages to follow the death of defendants. To explore this issue, we first conducted a legal analysis of appellate court decisions concerning punitive damages against deceased defendants. While the majority of courts suggest that punitive damages against deceased individuals are not appropriate, some argue that favorable policy implications of allowing punitive damages to follow the defendant’s death …

Emotion Dysregulation And Risky Sexual Behavior In Revictimization, Terri L. Messman-Moore, Kate L. Walsh, David K. Dilillo

Department of Psychology: Faculty Publications

Objective: The current study examined emotion dysregulation as a mechanism underlying risky sexual behavior and sexual revictimization among adult victims of child sexual abuse (CSA) and child physical abuse (CPA).

Methods: Participants were 752 college women. Victimization history, emotion dysregulation, and risky sexual behavior were assessed with anonymous, self-report surveys utilizing a cross-sectional design.

Results: Approximately 6.3% of participants reported CSA, 25.5% reported CPA, and 17.8% reported rape during adolescence or adulthood. CSA and CPA were associated with increased risk for adolescent/adult rape; 29.8% of CSA victims and 24.3% of CPA victims were revictimized. Path analytic models tested hypothesized relationships …

Description And Validation Of A Dynamical Systems Model Of Presynaptic Serotonin Function: Genetic Variation, Brain Activation And Impulsivity, Scott F. Stoltenberg, Parthasarathi Nag

Department of Psychology: Faculty Publications

Despite more than a decade of empirical work on the role of genetic polymorphisms in the serotonin system on behavior, the details across levels of analysis are not well understood. We describe a mathematical model of the genetic control of presynaptic serotonergic function that is based on control theory, implemented using systems of differential equations, and focused on better characterizing pathways from genes to behavior. We present the results of model validation tests that include the comparison of simulation outcomes with empirical data on genetic effects on brain response to affective stimuli and on impulsivity. Patterns of simulated neural firing …

Anxiolytic-Like Property Of Risperidone And Olanzapine As Examined In Multiple Measures Of Fear In Rats, Tao Sun, Wei He, Gang Hu, Ming Li

Department of Psychology: Faculty Publications

Atypical antipsychotics are also used in the treatment of anxiety-related disorders. Clinical and preclinical evidence regarding their intrinsic anxiolytic efficacy has been mixed. In this study, we examined the potential anxiolytic-like effects of risperidone and olanzapine, and compared them with haloperidol, chlordiazepoxide (a prototype of sedative–anxiolytic drug) or citalopram (a selective serotonin reuptake inhibitor). We used a composite of two-way avoidance conditioning and acoustic startle reflex model and examined the effects of drug treatments during the acquisition phase (Experiment 1) or extinction phase (Experiments 2 and 3) on multiple measures of conditioned and unconditioned fear/anxiety-like responses. In Experiment 4, we …

Physical, Psychological, And Sexual Intimate Partner Aggression Among Newlywed Couples: Longitudinal Prediction Of Marital Satisfaction, Jillian Panuzio, David K. Dilillo

Department of Psychology: Faculty Publications

This study examined associations between physical, psychological, and sexual intimate partner aggression (IPA) perpetration during the first year of marriage (T1) and victim marital satisfaction one (T2) and two (T3) years later among a sample of 202 newlywed couples. Prevalence rates of all forms of IPA were consistent with those documented in prior research. Higher levels of all types of IPA generally were associated with lower victim marital satisfaction at all time points, when controlling for initial levels of satisfaction. Couples who reported severe bidirectional psychological IPA demonstrated lower husband and wife marital satisfaction at T2 and lower husband satisfaction …

Rational Decision Making In Primates: The Bounded And The Ecological, Jeffrey R. Stevens

Department of Psychology: Faculty Publications

Primates constantly face decisions that influence their survival and reproduction. Continue foraging in this tree or move on to another? Expose oneself to a hidden predator by straying from the group or enjoy the safety of having other potential victims nearby? Defend one’s territory from invaders or abandon it and seek a new home? In all of these cases, primates must trade off the costs and benefits associated with uncertain and delayed decision outcomes. The outcomes of these choices influence survival and reproduction, and natural selection should favor those individuals whose choices lead to the propagation of their genes.

The …

Are All Perpetrators Alike? Comparing Risk Factors For Sexual Coercion And Aggression, Sarah Degue, David K. Dilillo, Mario J. Scalora

Department of Psychology: Faculty Publications

The present study developed and contrasted predictive models of male nonphysical sexual coercion (e.g., verbal pressure or manipulation) and physical sexual aggression (e.g., incapacitation, physical force, or threats) using a sample of 369 incarcerated males to identify shared and unique risk factors for each form of sexual perpetration. Results revealed a set of shared risk characteristics that predisposed individuals to both sexual coercion and aggression (i.e., belief in rape myths, sexual promiscuity, aggressive tendencies, and empathic deficits). In addition, findings indicated that whether the offenders engaged in only sexual coercion or also used more violent sexually aggressive tactics depended on …

Distinct Neural Mechanisms Underlying Acute And Repeated Administration Of Antipsychotic Drugs In Rat Avoidance Conditioning, Ming Li, Tao Sun, Chen Zhang, Gang Hu

Department of Psychology: Faculty Publications

Rationale — Acute antipsychotic treatment disrupts conditioned avoidance responding, and repeated treatment induces a sensitization- or tolerance-like effect. However, the neurochemical mechanisms underlying both acute and repeated antipsychotic effects remain to be determined.

Objective — The present study examined the neuroreceptor mechanisms of haloperidol, clozapine, and olanzapine effect in a rat two-way conditioned avoidance model.

Methods — Well-trained Sprague–Dawley rats were administered with haloperidol (0.05 mg/kg, sc), clozapine (10.0 mg/ kg, sc), or olanzapine (1.0 mg/kg, sc) together with either saline, quinpirole (a selective dopamine D2/3 agonist, 1.0 mg/ kg, sc), or 2,5-dimethoxy-4-iodo-amphetamine (DOI; a selective 5-HT2A/2C agonist, 2.5 mg/kg, …

Adult Coping With Childhood Sexual Abuse: A Theoretical And Empirical Review, Kate Walsh, Michelle A. Fortier, David Dilillo

Department of Psychology: Faculty Publications

Coping has been suggested as an important element in understanding the long-term functioning of individuals with a history of child sexual abuse (CSA). The present review synthesizes the literature on coping with CSA, first by examining theories of coping with trauma, and, second by examining how these theories have been applied to studies of coping in samples of CSA victims. Thirty-nine studies were reviewed, including eleven descriptive studies of the coping strategies employed by individuals with a history of CSA, eighteen correlational studies of the relationship between coping strategies and long-term functioning of CSA victims, and ten investigations in which …
