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 …

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 Jul 2014

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. …

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. …


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 Jan 2014

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 Mar 2013

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 Aug 2012

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 …


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 Jan 2012

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 …


Juries And Eyewitnesses, Cindy Laub, Brian H. Bornstein Jan 2008

Juries And Eyewitnesses, Cindy Laub, Brian H. Bornstein

Department of Psychology: Faculty Publications

The role of an eyewitness can be extremely important in the legal system, as eyewitness testimony and eyewitness identifications play a major role in the prosecution of a criminal defendant. Often the courts are left to rely solely on an eyewitness because there is no other physical evidence. This leaves the jury to rely on a witness’s testimony. Jurors are asked to determine the credibility of an eyewitness at trial when rendering a verdict, and jurors have been found to place more emphasis on eyewitness testimony than on any other kind of evidence. However, there are numerous documented cases of …


Stress And Eyewitness Memory, Ani A. Aharonian, Brian H. Bornstein Jan 2008

Stress And Eyewitness Memory, Ani A. Aharonian, Brian H. Bornstein

Department of Psychology: Faculty Publications

Stress exerts complex effects on eyewitness memory. On the whole, it has a negative effect, but this can be quite variable depending on the level of stress and the aspect of the witnessed event that one is trying to remember. Stress operates similarly in affecting person recognition (i.e., lineup performance) and recall of event details.


Child Sexual Abuse, David J. Hansen, Kathryn R. Wilson Jan 2007

Child Sexual Abuse, David J. Hansen, Kathryn R. Wilson

Department of Psychology: Faculty Publications

Although definitions can vary across legal, clinical, and research contexts, sexual abuse is commonly defined as sexual acts between a youth and an older person (e.g., by 5 years or more) in which the dominance of the older person is used to exploit or coerce the youth. Behaviors may include noncontact (e.g., exposure) and contact (e.g., intercourse) offenses.


Developmental Needs Of Adolescents And Media, Laura M. Padilla-Walker Jan 2006

Developmental Needs Of Adolescents And Media, Laura M. Padilla-Walker

Department of Psychology: Faculty Publications

Adolescence is marked by a number of physical, cognitive, and social changes that interact to create a number of developmental needs specific to this age group. As adolescents seek to define themselves independently of their parents, they often turn to media as sources of self-socialization and of messages about their identity in terms of gender, sexuality, and ethnicity. Although parents and peers remain influential during this transition, this entry focuses on adolescents’ use of media to navigate developmental changes and cope with the daily difficulties of being teenagers, and on the role of media in shaping adolescents’ development of identity …


Parenting, Julia C. Torquati Jan 2004

Parenting, Julia C. Torquati

Department of Psychology: Faculty Publications

How can parents successfully care for their children in the context of homelessness? This is a significant question because families with children represent approximately 40 percent of the homeless population in the United States, and the number of homeless children has been growing since the early 1980s. Negative consequences of homelessness to children’s health, education, and emotional and social development have been well documented. Homeless families in the United States can be considered a subset of limited-resource families, and as such they share some of the same challenges to effective parenting. However, homeless parents face additional challenges, and these challenges …
