Research Info:

In the Neuropsychology & Psychopathology Lab (NPL) we utilize cognitive neuropsychology, experimental psychopathology, and meta-analytic research methodologies to gain insight into the association between psychopathological processes, cognitive functioning, and real-life daily functioning.

We are currently interested in:

1. Cognitive functioning in obsessive-compulsive and related disorders, as well as related psychological constructs.
2. Transdiagnostic patterns of cognitive dysfunction associated with psychological disorders, and psychopathological processes. We are particularly interested in factors associated with underperformance on neuropsychological tests, including motivational factors, self-perceptions, and self-efficacy.
3. Ecological and predictive validity of neuropsychological tests/functions/deficits in the context of real-life daily functions across clinical and non-clinical populations.
4. The definition and quantification of cognitive dysfunction, and particularly the terms ‘impairment’ and ‘deficit’.
5. The translational value and legitimacy of cognitive ‘endophenotypes’ and disorder-specific ‘markers’.
6. Psychopathological mechanisms and neuropsychological correlates of Misophonia.
7. Impulsivity and response inhibition in the context of the impulsive-compulsive continuum.

Dr. Aljunaidy's research interest is interdisciplinary and focuses on the link between interior design and people’s mental health. Dr. Aljunaidy is conducting research about how interior design can support people who suffer from dementia, and people who suffer from stress.

One of my main research interests has involved different factors that affect functional abilities, such as work performance, cognitive performance, and neuropsychological functioning. Previous studies have examined whether induced pain reduces performance on measures of memory, attention, and other cognitive abilities. To date, we have found little to no impact of pain on several cognitive measures. A related research interest has involved the influence of disability exaggeration, including malingering, on different psychometric instruments, and the ability of validity measures to detect malingering. In addition, I am interested in the ways that different forms of psychopathology may impair neuropsychological functioning, and to what extent such deficits may be explained by self-fulfilling expectations of poorer performance. Although in the early stages currently, I am also interested in the efficacy of a low-intensity Behavioral Activation approach as a lower-cost and more accessible treatment for depression as well as PTSD.

Dr. Graham's research is in the area of social/affective neuroscience; in particular, the electrophysiological and behavioral correlates of visual processing evoked in response to stimuli of motivational significance (e.g., social and appetitive stimuli). Current research interests lie in understanding how individual differences in attitudes and exposure to target stimuli moderate attentional processes and event-related potentials (ERPs) to appetitive and motivationally relevant stimuli like faces, bodies, food, alcohol, and tobacco. This research enriches our understanding of motivation from a basic science perspective, with implications for our understanding of phenomena such as social anxiety and prejudice, as well as health-risk behaviors.

In my research, I have applied social psychological principles to the understanding of interpersonal factors in health and the process of medical care. My work deals with two main areas: (1) patients' adherence to medical recommendations for healthy behavior and the prevention and treatment of disease and (2) medical visit communication in the dyadic health professional-patient relationship. I am particularly interested in psychosocial factors that predict adherence and health behavior change as well as interventions to improve adherence and healthy behavior in patients with chronic illnesses. Current research involves development and testing of mobile health interventions.

Dr. Kelemen’s research focuses on metacognition, which includes the monitoring and control of one’s own cognitive processes. Specifically, Dr. Kelemen focuses on individuals’ judgments of learning (JOLs) about their future memory performance. He has examined factors that influence JOL accuracy, that is, the relationship between JOLs and subsequent memory performance. These factors include characteristics of the items themselves, study procedures, and the influence of mild stimulants including caffeine and nicotine. Most recently, he has collaborated on research focused on the role of exercise on memory and JOLs.

Broadly, my research interests are in social, personality, cultural and health psychology areas. Specifically, I investigate how personality factors interact with social and cultural factors to influence personal health decisions. My aim in research is also the improvement of health behaviors and outcomes for at risk populations. I have examined women’s adherence to following medical advice, e.g. taking folic acid, to prevent neural tube defects and couple’s engagement of high risk sexual behaviors in interpersonal relationships that place individuals at risk for HIV. The research in these areas has identified key risk factors and has advanced recommendations to reduce such risks.

More recently my interests have turned to emotion recognition research. Individuals differ in their abilities to detect emotions in others. My research explores psychological states and physical conditions that impair or facilitate emotional recognition in others. Also recently, a colleague and I have investigated the psychology of the treatment of immigrants in this country. Specifically, we examined immigrant characteristics and key psychological factors, and their links to perceivers’ feelings and behaviors toward immigrants.

Though the search for human universals is important, I have discovered that emotions, cognitions and behaviors cannot be fully understood unless their culture, is taken into account. We are embedded in contexts that shape and give meaning to our thoughts and behaviors. Thus, it is my belief that the key to understanding human behavior is knowing culture.

These are the areas of research that are of great interest to me.

My research spans the subfields of cultural, health, and cognitive psychology. In my Inclusion, Diversity, Equity, and Awareness (IDEA) lab, we explore how culture and diverse social identities influence behavior, cognition, health, and well-being. These identities may include race, ethnicity, nationality, gender, sexual orientation, (dis)ability, and more. Of particular interest are the lived experiences of underrepresented people, how those experiences relate to inclusion and equity, and the impact of those experiences on mental and physical health. Current projects are investigating a variety of research questions, including how disordered eating behaviors vary in LGBTQ+ communities and across different racial and ethnic groups, how enculturation and ethnocultural empathy relate to prosocial behaviors and attitudes, how cultural and other factors affect the well-being of Hispanic individuals, and how prejudicial and discriminatory biases impact the interpersonal relationships and well-being of deaf individuals.

At this time, I have three main areas of research interest. First, I engage in Scholarship of Teaching research on how what faculty do (and teach) in the classroom has an impact student tolerance for ambiguity in dealing with diverse others. Second, I have conducted several large-scale studies (across multiple cities) assessing cynicism in police officers. I am especially interested in what factors lead to the development of cynicism in officers, the impact of cynicism in officers (in terms of their personal lives and how they conduct themselves as officers) and what agencies might do to reduce the negative effects of cynicism in officers. Lastly, I have worked with athletes and athletic programs at the university level to assess the relationships between personality characteristics and vulnerability to and recovery from injury and how athletes attribute their own injuries and those of their teammates.

My program of research broadly aims to understand, improve the assessment of, and intervene upon processes that confer risk for suicidal ideation, intent, and behavior. Using a transdiagnostic framework, my research addresses two primary questions: (1) what contributes to the development and maintenance of suicidal thoughts and behaviors? and (2) when (and under what circumstances) do transitions from suicidal thoughts to actions occur? Specifically, one line of my research focuses on the interplay between cognitive dysfunction (rumination, attentional biases, hopelessness) and biobehavioral factors (agitation, sleep disturbances, overarousal) as short-term risk factors for suicidal ideation and attempts. Another line of my research has focused on general and suicide-specific factors that may facilitate a transition from suicidal thoughts to actions, particularly in the hours to days preceding a suicide attempt.

Future complementary areas of research include:
1. Examining the phenomenology, etiology, and temporal dynamics of acute suicidal crises in the hours preceding a suicide attempt
2. Determining whether there are individual differences (e.g., genetic, neurobiological, psychological, sociocultural, and/or pragmatic moderators) in the trajectories of short-term suicide risk between individuals
3. Innovating suicide risk assessment and management through the development, validation, and dissemination/implementation of scalable, feasible, and tailorable interventions
4. Improving the precision and ecological validity of measurement
5. Applying advanced quantitative methods to these research questions

Dr. Tooley's research seeks to discover how structural (especially grammatical) knowledge is represented and accessed during normal language use. I probe structural representation in language via research on structural priming effects during online comprehension and production of sentences, using measures such as eye tracking, reading times, and elicited speech. I also apply structural priming paradigms to investigate how aspects of prosody (e.g., rate, intonation, and pitch) are represented and how structure is processed in other cognitive domains, such as mathematics.
