The Signature Of Undetected Change: An Exploratory Electrotomographic Investigation Of Gradual Change Blindness, John E. Kiat, Michael D. Dodd, Robert F. Belli, Jacob E. Cheadle

Department of Psychology: Faculty Publications

Neuroimaging-based investigations of change blindness, a phenomenon in which seemingly obvious changes in visual scenes fail to be detected, have significantly advanced our understanding of visual awareness. The vast majority of prior investigations, however, utilize paradigms involving visual disruptions (e.g., intervening blank screens, saccadic movements, “mudsplashes”), making it difficult to isolate neural responses toward visual changes cleanly. To address this issue in this present study, high-density EEG data (256 channel) were collected from 25 participants using a paradigm in which visual changes were progressively introduced into detailed real-world scenes without the use of visual disruption. Oscillatory activity associated with undetected …

Whose Preferences Matter? A Patient-Centered Approach For Eliciting Treatment Goals, Nananda F. Col, Andrew J. Solomon, Vicky Springman, Calvin P. Garbin, Carolina Ionete, Lori Pbert, Enrique Alvarez, Brenda Tierman, Ashli Hopson, Christen Kutz, Idanis Berrios Morales, Carolyn Griffin, Glenn Phillips, Long H. Ngo

Department of Psychology: Faculty Publications

Background. Patients facing a high-stakes clinical decision are often confronted with an overwhelming array of options. High-quality decisions about treatment should reflect patients’ preferences as well as their clinical characteristics. Preference-assessment instruments typically focus on pre-selected clinical outcomes and attributes chosen by the investigator. Objective. We sought to develop a patient-centered approach to elicit and compare the treatment goals of patients with multiple sclerosis (MS) and healthcare providers (HCPs). Methods. We conducted five nominal group technique (NGT) meetings to elicit and prioritize treatment goals from patients and HCPs. Five to nine participants in each group responded silently to one question …

Computerized neuropsychological testing has become an important tool in the identification and management of sports-related concussions; however, the psychometric effect of repeat testing has not been studied extensively beyond test–retest statistics. The current study analyzed data from Division I collegiate athletes who completed Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) baseline assessments at four sequential time points that varied over the course of their athletic careers. Administrations were part of a larger National Institutes of Health (NIH) study. Growth curve modeling showed that the two memory composite scores increased significantly with successive administrations: Change in Verbal Memory was best represented …

Effects Of Repeated Quetiapine Treatment On Conditioned Avoidance Responding In Rats, Jun Gao, Min Feng, Natashia Swalve, Collin Davis, Nan Sui, Ming Li

Department of Psychology: Faculty Publications

The present study characterized the behavioral mechanisms of avoidance–disruptive effect of quetiapine in the conditioned avoidance response test under two behavioral testing (2 warning signals vs. 1 warning signal) and two drug administration conditions (subcutaneous vs. intravenous). In Experiments 1 and 2, well-trained adult male Sprague-Dawley rats were tested under the subcutaneous (s.c.) quetiapine treatment (5.0, 15.0, 25.0, 50.0 mg/kg) for 7 days in a novel procedure consisting of two conditioned stimuli (CS) (white noise serving as CS1 and pure tone as CS2). Only the highest dose (50.0 mg/kg) produced a persistent suppression of the avoidance response without impairing the …

Behavioral And Pharmacological Investigation Of Anxiety And Maternal Responsiveness Of Postpartum Female Rats In A Pup Elevated Plus Maze, Yu Yang, Jingxue Qin, Weihai Chen, Hong Chen, Ming Li

Department of Psychology: Faculty Publications

The present study investigated the validity of a novel pup-based repeated elevated plus maze task to detect reduced anxiety and increased maternal responsiveness in postpartum female rats and explored the roles of dopamine D2, serotonin transporter and GABA/benzodiazepine receptors in the mediation of these processes. Sprague–Dawley postpartum or nulliparous female rats were tested 4 times every other day on postpartum days 4, 6 and 8 in an elevated plus maze with 4 pups or 4 pup-size erasers placed on each end of the two open arms. When tested with erasers, untreated postpartum mother rats entered the open arms proportionally more …

The Interplay Of Trait Anger, Childhood Physical Abuse, And Alcohol Consumption In Predicting Intimate Partner Aggression, Rosalita C. Maldonado, Laura E. Watkins, David Dilillo

Department of Psychology: Faculty Publications

The current study examined three well-established risk factors for intimate partner aggression (IPA) within Finkel and Eckhardt’s I³ model, including two impellance factors—trait anger and childhood physical abuse history—and the disinhibiting factor of alcohol consumption. Participants were 236 male and female college students in a committed heterosexual dating relationship who completed a battery of self-report measures assessing childhood physical abuse, trait anger, alcohol consumption, and IPA perpetration. Results revealed a significant three-way interaction showing that as the disinhibition factor alcohol consumption increased, the interaction of the two impelling factors, trait anger and childhood physical abuse, became increasingly more positive. …

Antioxidant Gene Therapy Against Neuronal Cell Death, Juliana Navarro-Yepes, Laura Zavala-Flores, Anandhan Annadurai, Fang Wang, Maciej Skotak, Namas Chandra, Ming Li, Aglaia Pappa, Daniel Martinez-Fong, Luz Maria Del Razo, Betzabet Quintanilla-Vega, Rodrigo Franco

Department of Psychology: Faculty Publications

Oxidative stress is a common hallmark of neuronal cell death associated with neurodegenerative disorders such as Alzheimer's disease, Parkinson's disease, as well as brain stroke/ischemia and traumatic brain injury. Increased accumulation of reactive species of both oxygen (ROS) and nitrogen (RNS) has been implicated inmitochondrial dysfunction, energy impairment, alterations in metal homeostasis and accumulation of aggregated proteins observed in neurodegenerative disorders, which lead to the activation/modulation of cell death mechanisms that include apoptotic, necrotic and autophagic pathways. Thus, the design of novel antioxidant strategies to selectively target oxidative stress and redox imbalance might represent important therapeutic approaches against neurological disorders. …

Estimating Child Sleep From Parent Report Of Time In Bed: Development And Evaluation Of Adjustment Approaches, Timothy D. Nelson, Alyssa Lundahl, Dennis L. Molfese, Rachel N. Waford, Adrienne Roman, David Gozal, Victoria J. Molfese, Melissa C. Ferguson

Department of Psychology: Faculty Publications

Objective To develop and evaluate adjustment factors to convert parent-reported time in bed to an estimate of child sleep time consistent with objective measurement. Methods A community sample of 217 children aged 4–9 years (mean age = 6.6 years) wore actigraph wristwatches to objectively measure sleep for 7 days while parents completed reports of child sleep each night. After examining the moderators of the discrepancy between parent reports and actigraphy, 3 adjustment factors were evaluated. Results Parent report of child sleep overestimated nightly sleep duration by ~24 min per night relative to actigraphy. Child age, gender, and sleep quality all …

Adult Response To Olanzapine Or Clozapine Treatment Is Altered By Adolescent Antipsychotic Exposure: A Preclinical Test In The Phencyclidine Hyperlocomotion Model, Qing Shu, Gang Hu, Ming Li

Department of Psychology: Faculty Publications

This study examined how repeated olanzapine (OLZ) or clozapine (CLZ) treatment in adolescence alters sensitivity to the same drug in adulthood in the phencyclidine (PCP) hyperlocomotion model. Male adolescent Sprague-Dawley rats (postnatal day (P) 44–48) were first treated with OLZ (1.0 or 2.0 mg/kg, subcutaneously (sc)) or CLZ (10.0 or 20.0 mg/kg, sc) and tested in the PCP (3.2 mg/kg, sc)-induced hyperlocomotion model for five consecutive days. Then a challenge test with OLZ (0.5 mg/kg) or CLZ (5.0 mg/kg) was administered either during adolescence (~P 51) or after the rats matured into adults (~P 76 and 91). During adolescence, repeated …

Is Brain-Derived Neurotrophic Factor A Possible Mechanism Underlying Risperidone Sensitization In Adolescent Rats?, Qing Shu, Gang Hu, Ming Li

Department of Psychology: Faculty Publications

Risperidone is one of the most widely used atypical antipsychotic drugs and is approved for the treatment of mental disorders (eg. schizophrenia, autism) in children and adolescents. The present study investigated the repeated treatment effect of risperidone and associated neurotropic mechanism in the phencyclidine (PCP)-induced hyperlocomotion model in adolescent rats. We examined whether repeated risperidone treatment would cause a sensitized inhibition of PCP-induced hyperlocomotion in adolescent rats, and whether such a sensitization effect was mediated by risperidone-induced alterations in Brain-Derived Neurotrophic Factor (BDNF), an important biomarker which plays a role in neuropathology of schizophrenia and action of antipsychotic medications. Male …

Parametric Studies Of Antipsychotic-Induced Sensitization In The Conditioned Avoidance Response Model: Roles Of Number Of Drug Exposure, Drug Dose, And Test–Retest Interval, Natashia Swalve, Ming Li

Department of Psychology: Faculty Publications

Repeated haloperidol and olanzapine treatment produces an enhanced disruption of avoidance responding, a validated measure of antipsychotic activity. Experimental parameters affecting this sensitization-like effect have not been thoroughly examined. The present study investigated the role of three parameters (number of injections, dose, and interval between initial exposure and challenge) in antipsychotic sensitization in the conditioned avoidance response paradigm. Well-trained Sprague–Dawley rats received different numbers of drug treatment (1–5 days) or different doses of haloperidol (0.025–0.10 mg/kg, subcutaneously) or olanzapine (0.5–2.0 mg/kg, subcutaneously). After certain time intervals (4, 10 or 17 days), they were tested for the expression of haloperidol or …

Neural Basis Of The Potentiated Inhibition Of Repeated Haloperidol And Clozapine Treatment On The Phencyclidine-Induced Hyperlocomotion, Changjiu Zhao, Tao Sun, Ming Li

Department of Psychology: Faculty Publications

Clinical observations suggest that antipsychotic effect starts early and increases progressively over time. This time course of antipsychotic effect can be captured in a rat phencyclidine (PCP)-induced hyperlocomotion model, as repeated antipsychotic treatment progressively increases its inhibition of the repeated PCP-induced hyperlocomotion. Although the neural basis of acute antipsychotic action has been studied extensively, the system that mediates the potentiated effect of repeated antipsychotic treatment has not been elucidated. In the present study, we investigated the neuroanatomical basis of the potentiated action of haloperidol (HAL) and clozapine (CLZ) treatment in the repeated PCP-induced hyperlocomotion. Once daily for five consecutive days, …

Communication-Based Assessment Of Developmental Age For Young Children With Developmental Disabilities, Shari L. Deveney, Lesa Hoffman, Cynthia J. Cress

Department of Psychology: Faculty Publications

Purpose: In this study, the authors compared a multiple-domain strategy for assessing developmental age of young children with developmental disabilities who were at risk for long-term reliance on augmentative and alternative communication (AAC) with a communication-based strategy composed of receptive language and communication indices that may be less affected by physically challenging tasks than traditional developmental age scores.

Method: Participants were 42 children (age 9–27 months) with developmental disabilities and who were at risk for long-term reliance on AAC. Children were assessed longitudinally in their homes at 3 occasions over 18 months using multiple-domain and communication-based measures. Confirmatory factor analysis …

Linking Outcomes From Peabody Picture Vocabulary Test Forms Using Item Response Models, Lesa Hoffman, Jonathan Templin, Mabel L. Rice

Department of Psychology: Faculty Publications

Purpose: The present work describes how vocabulary ability as assessed by 3 different forms of the Peabody Picture Vocabulary Test (PPVT; Dunn & Dunn, 1997) can be placed on a common latent metric through item response theory (IRT) modeling, by which valid comparisons of ability between samples or over time can then be made.

Method: Responses from 2,625 cases in a longitudinal study of 697 persons for 459 unique PPVT items (175 items from Peabody Picture Vocabulary Test—Revised [PPVT–R] Form M [Dunn & Dunn, 1981], 201 items from Peabody Picture Vocabulary Test—3 [PPVT–3] Form A [Dunn & Dunn, 1997], and …

Methamphetamine-Associated Psychosis, Kathleen M. Grant, Tricia D. Le Van, Sandra M. Wells, Ming Li, Scott F. Stoltenberg, Howard E. Gendelman, Gustavo Carlo, Rick A. Bevins

Department of Psychology: Faculty Publications

Methamphetamine (METH) is a frequent drug of abuse in U.S. populations and commonly associated with psychosis. This may be a factor in frequent criminal justice referrals and lengthy treatment required by METH users. Persecutory delusions and auditory hallucinations are the most consistent symptoms of METH-associated psychosis (MAP). MAP has largely been studied in Asian populations and risk factors have varied across studies. Duration, frequency and amount of use as well as sexual abuse, family history, other substance use, and co-occurring personality and mood disorders are risk factors for MAP. MAP may be unique with its long duration of psychosis and …

Gender, Gender Roles, And Anxiety: Perceived Confirmability Of Self Report, Behavioral Avoidance, And Physiological Reactivity, Milena Stoyanova, Debra Anne Hope

Department of Psychology: Faculty Publications

Despite the well-documented gender effect in anxiety, less is known about contributing factors to women’s greater risk for anxiety and fears. The present study examined the relationship between gender, gender role orientation (i.e., expressivity/instrumentality) and fear of harmless insects (tarantula), using a multimodal approach of self-report measures, a Behavioral Approach Test (BAT), and physiological reactivity. Participants (144 college students; 67 women, 77 men) completed a questionnaire packet and then were instructed to approach a tarantula. We were unable to replicate Pierce and Kirkpatrick’s (1992) findings that men underreport anxiety. Consistent with the literature, women in the study experienced greater anxiety …

Differential Effects Of Acute Amphetamine And Phencyclidine Treatment And Withdrawal From Repeated Amphetamine Or Phencyclidine Treatment On Social Interaction And Social Memory In Rats, Ming Li, Wei He, Rebecca Munro

Department of Psychology: Faculty Publications

Although animal models based on amphetamine (AMPH) or phencyclidine (PCP) treatment have been used extensively to study the neurobiological and behavioral characteristics of schizophrenia, there are conflicting reports regarding their validity in modeling the negative symptoms and cognitive deficits of schizophrenia. The present study examined how acute AMPH or PCP treatment (Experiment 1) and withdrawal from repeated AMPH treatment (Experiment 2) or PCP treatment (Experiment 3) affects social behavior and social recognition memory in male Sprague-Dawley rats. Each subject was tested on two consecutive days. On the first day, the rats were tested four times (5 min/each) at 10-min intervals …

Integrating Sexual Objectification With Object Versus Person Recognition: The Sexualized-Body-Inversion Hypothesis, Philippe Bernard, Sarah J. Gervais, Jill Allen, Sophie Campomizzi, Olivier Klein

Department of Psychology: Faculty Publications

In the study reported here, we tested the novel sexualized-body-inversion hypothesis. Integrating research and theory on objectification and person versus object recognition, we examined whether sexualized women, but not sexualized men, are recognized in the same way as objects are. According to objectification theory (Fredrickson & Roberts, 1997), female bodies are scrutinized and evaluated to a greater degree than male bodies are, which leads to sexual objectification of women. Defined as viewing or treating an individual as a sexualized body, or as sexualized body parts, available for satisfying the needs and desires of other people (Bartky, 1990), sexual objectification has …

Contextual And Behavioral Control Of Antipsychotic Sensitization Induced By Haloperidol And Olanzapine, Chen Zhang, Ming Li

Department of Psychology: Faculty Publications

Repeated administration of haloperidol (HAL) and olanzapine (OLZ) causes a progressively enhanced disruption of the conditioned avoidance response (CAR) and a progressively enhanced inhibition of phencyclidine (PCP)-induced hyperlocomotion in rats (termed antipsychotic sensitization). Both actions are thought to reflect intrinsic antipsychotic activity. The present study examined the extent to which antipsychotic- induced sensitization in one model (e.g. CAR) can be transferred or maintained in another (e.g. PCP hyperlocomotion) as a means of investigating the contextual and behavioral controls of antipsychotic sensitization. Well-trained male Sprague-Dawley rats were first repeatedly tested in the CAR or the PCP (3.2 mg/kg, subcutaneously) hyperlocomotion model …

Intertemporal Choice In Lemurs, Jeffrey R. Stevens, Nelly Mühlhoff

Department of Psychology: Faculty Publications

Different species vary in their ability to wait for delayed rewards in intertemporal choice tasks. Models of rate maximization account for part of this variation, but other factors such as social structure and feeding ecology seem to underly some species differences. Though studies have evaluated intertemporal choice in several primate species, including Old World monkeys, New World monkeys, and apes, prosimians have not been tested. This study investigated intertemporal choices in three species of lemur (black-and- white ruffed lemurs, Varecia variegata, red ruffed lemurs, Varecia rubra, and black lemurs, Eulemur macaco) to assess how they compare to …

Clozapine, But Not Olanzapine, Disrupts Conditioned Avoidance Response In Rats By Antagonizing 5-Ht2a/2c Receptors, Ming Li, Tao Sun, Alexa Mead

Department of Psychology: Faculty Publications

The present study was designed to assess the role of 5-HT_2A/2C receptors in the acute and repeated effect of clozapine and olanzapine in a rat conditioned avoidance response model, a validated model of antipsychotic activity. Male Sprague–Dawley rats that were previously treated with either phencyclidine (0.5–2.0 mg/kg, sc), amphetamine (1.25–5.0 mg/kg, sc), or saline and tested in a prepulse inhibition of acoustic startle study were used. They were first trained to acquire avoidance response to a white noise (CS1) and a pure tone (CS2) that differed in their ability to predict the occurrence of footshock. Those who acquired avoidance …

Confirmatory Factor Analysis Of The Preschool Behavioral And Emotional Rating Scale (Prebers) With Preschool Children With Disabilities, Cynthia J. Cress, Lori Synhorst, Michael Epstein, Elizabeth Allen

Department of Psychology: Faculty Publications

The Preschool Behavioral and Emotional Rating Scale (PreBERS) is a standardized, norm-referenced instrument that assesses emotional and behavioral strengths of preschool children. This study investigated whether the PreBERS four-factor structure (i.e., emotional regulation, school readiness, social confidence, and family involvement) could be replicated with an early childhood special education (ECSE) sample of children. Teachers who participated in the study rated a total of 1,103 preschool children with disabilities. Confirmatory factor analysis determined the extent to which the ECSE data fit the original four-factor PreBERS structure identified with the national normative sample. Results indicated that the four-factor structure demonstrated an acceptable …

Time Course Of Prepulse Inhibition Disruption Induced By Dopamine Agonists And Nmda Antagonists: Effects Of Drug Administration Regimen, Ming Li, Wei He, Jing Chen

Department of Psychology: Faculty Publications

Prepulse inhibition (PPI) of acoustic startle response is impaired in patients with schizophrenia and in animals acutely treated with dopamine agonists and NMDA antagonists. In this study, we investigated the time course of PPI disruption induced by repeated amphetamine, quinpirole, phencyclidine (PCP), and dizocilpine (MK-801) treatment. We focused on how PPI disruption development was influenced by drug administration regimens, comparing a constant versus an escalating dosing regimen. Male Sprague–Dawley rats were repeatedly treated with amphetamine (1.25–5.0 mg/kg, or constant 5.0 mg/kg, sc), PCP (0.50–2.0 mg/kg, or constant 0.5, 1.0 or 2.0 mg/kg, sc), quinpirole (0.03–0.12 mg/kg, or constant 0.12 mg/kg, …

The Cumulative Impact Of Sexual Revictimization On Emotion Regulation Difficulties: An Examination Of Female Inmates, Kate Walsh, David K. Dilillo, Mario J. Scalora

Department of Psychology: Faculty Publications

The present study examined associations between child sexual abuse (CSA), adult sexual victimization, and emotion regulation difficulties in a sample of 168 incarcerated women. Approximately 50% of the participants reported CSA, 54% reported adult sexual victimization, and 38% reported sexual revictimization (i.e., CSA and adult victimization). Revictimized women reported significantly greater difficulties with several facets of emotion regulation when compared to singly victimized and nonvictimized women. Interestingly, singly victimized women did not demonstrate greater emotion regulation deficits when compared to nonvictims. Findings suggest that the negative impact of victimization experiences on adult emotion regulation abilities may be cumulative. Furthermore, they …

Time Course Of The Attenuation Effect Of Repeated Antipsychotic Treatment On Prepulse Inhibition Disruption Induced By Repeated Phencyclidine Treatment, Ming Li, Erik He, Nick Volf

Department of Psychology: Faculty Publications

Antagonism of prepulse inhibition (PPI) deficits produced by psychotomimetic drugs has been widely used as an effective tool for the study of the mechanisms of antipsychotic action and identifying potential antipsychotic drugs. Many studies have relied on the acute effect of a single administration of antipsychotics, whereas patients with schizophrenia are treated chronically with antipsychotic drugs. The clinical relevance of acute antipsychotic effect in this model is still an open question. In this study, we investigated the time course of repeated antipsychotic treatment on persistent PPI deficit induced by repeated phencyclidine (PCP) treatment. After a baseline test with saline, male …

Interventions For Families Victimized By Child Sexual Abuse: Clinical Issues And Approaches For Child Advocacy Center-Based Services, Poonam Tavkar, David J. Hansen

Department of Psychology: Faculty Publications

Child sexual abuse poses serious mental health risks, not only to child victims but also to non-offending family members. As the impact of child sexual abuse is heterogeneous, varied mental health interventions should be available in order to ensure that effective and individualized treatments are implemented. Treatment modalities for child victims and non-offending family members are identified and described. The benefits of providing on-site mental health services at Child Advocacy Centers to better triage and provide care are discussed through a description of an existing Child Advocacy Center-based treatment program. Recommendations for research and clinical practice are provided.

The Good, The Bad, And The Rare: Memory For Partners In Social Interactions, Jenny Volstorf, Jörg Rieskamp, Jeffrey R. Stevens

Department of Psychology: Faculty Publications

For cooperation to evolve via direct reciprocity, individuals must track their partners’ behavior to avoid exploitation. With increasing size of the interaction group, however, memory becomes error prone. To decrease memory effort, people could categorize partners into types, distinguishing cooperators and cheaters. We explored two ways in which people might preferentially track one partner type: remember cheaters or remember the rare type in the population. We assigned participants to one of three interaction groups which differed in the proportion of computer partners’ types (defectors rare, equal proportion, or cooperators rare). We extended research on both hypotheses in two ways. First, …

Spatial Discounting Of Food And Social Rewards In Guppies (Poecilia Reticulata), Nelly Mühlhoff, Jeffrey R. Stevens, Simon M. Reader

Department of Psychology: Faculty Publications

In temporal discounting, animals trade off the time to obtain a reward against the quality of a reward, choosing between a smaller reward available sooner versus a larger reward available later. Similar discounting can apply over space, when animals choose between smaller and closer versus larger and more distant rewards. Most studies of temporal and spatial discounting in non-human animals use food as the reward, and it is not established whether animals trade off other preferred stimuli in similar ways. Here, we offered female guppies (Poecilia reticulata) a spatial discounting task in which we measured preferences for a larger reward …

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 …
