SPLAT Lab (Shiota)
The Shiota Psychophysiology Laboratory for Affective Testing (SPLAT Lab) conducts research on the basic nature and translational implications of human emotion, with particular emphasis on positive emotions, emotional processes in close relationships, and emotional mechanisms of health behavior and behavior change. Studies use a variety of designs (e.g., experimental, longitudinal/daily diary, cross-sectional) as well as behavioral, cognitive, physiological, narrative, and questionnaire measures. Core themes include:
Positive Emotions. Researchers have long differentiated several negative emotions, such as sadness, fear, and anger, but empirical research on potentially "discrete" positive emotions is more recent. Our lab takes an evolutionary approach to defining multiple positive emotions, and studies the extent of overlap and differentiation among these states. We use the proposed adaptive functions of each emotion as a basis for predicting various aspects of emotional responding, including aspects of subjective experience, profiles of autonomic nervous system reactivity, nonverbal expression, and implications for social cognition and behavior. Current projects focus in particular on awe, amusement/humor, and varieties of love.
Emotional Processes in Close Relationships. Although emotions feel like intensely personal experiences, they are also profoundly important for our interactions with other people. We form impressions of new people, build and maintain close relationships, and coordinate dyadic and group action all with the help of emotions. Our research investigates some of the mechanisms by which emotions support relationships, and how the quality of close relationships impacts emotional experience. Current projects address perceived social support and a sense of belonging, the development of attachment bonds, and the ways in which relationship partners regulate each other’s emotions during stressful times.
Emotional Mechanisms of Behavior Change. Several of the great societal problems of our time involve behavior. Behaviors such as smoking, disordered alcohol and drug use, poor diet, and lack of exercise are major causes of preventable disease. Unsustainable consumption of energy and resources is creating a global environmental crisis. New media and internet-based technologies are drastically re-shaping human social interaction, economic decision-making, and participation in public life, with unpredictable and sometimes problematic consequences. Emotion is woven into the fabric of human behavior across these domains. Eating a candy bar, drinking to excess, buying a lottery ticket or a more expensive car than you can afford, and checking social media incessantly for “likes” of your last post are all mediated by neural mechanisms supporting our emotional responses to rewards. Emotional stress and exhaustion increase the difficulty of regulating our behavior, whether it’s resisting the temptation to smoke, taking the time to fact-check a political ad, or remembering to bring reusable bags to the store. In a growing area of focus, we’re investigating ways in which basic knowledge about emotions and emotion regulation can be applied to guide new techniques for promoting healthy and sustainable behavior. Current projects include development and evaluation of trainings to administer naloxone (a drug to reverse opioid overdose), as well as assessment of and intervention to reduce stigma/prejudice associated with substance use disorder.
The application period for Fall 2024 admission to the ASU Doctoral Program in Social Psychology is closed. Dr. Shiota will consider applications from potential graduate students to join the lab in Fall 2025.

Graduate Students
| Carley Vornlocher, Doctoral Student, Social Psychology Carley is a 5th-year student in the Social Psychology Ph.D. program at ASU. Carley's research employs experimental, intervention, and intensive-longitudinal designs to examine the roles emotional and relational processes play in health, well-being, and behavior change. Through the lens of attachment theory, Carley's research examines the affective and cognitive mechanisms by which close relationships can bolster health, well-being, and goal pursuit. Other projects investigate how certain emotions and emotion regulation strategies influence well-being and/or may be leveraged to help initiate and sustain engagement in positive health behaviors. Contact: cvornloc@asu.edu. |
| Jamie Katz, Doctoral Student, Social Psychology Jamie Katz is a 3rd-year student in the Social Psychology Ph.D. program at ASU, and the current SPLAT Lab Manager. Her research investigates the effects of awe, a distinct positive emotion, on memory, cognition, and behavior. Current projects investigate how awe, along with other discrete emotion states, affect memory for visual stimuli and physiological responses. She is also interested more generally in how positive emotions relate to well-being. Contact: jkatz13@asu.edu. |

- For the first year, 399/499 enrollment at 10 hours/week
- In-person attendance at weekly lab meetings, Wednesdays 4:30-5:30pm
Research Assistants in the SPLAT lab contribute to every step of the scientific process, from discussion of theory to hypothesis generation, study design, data collection and processing, and interpretation of study findings. RAs have a wide range of duties, all of which provide training in the varied methods used in emotion research. Dr. Shiota and the graduate students in the lab rotate RAs through duties to ensure that each student gets broad exposure to the research process, and tailor the experience to each student’s interests and goals. Duties may include:
- In-person attendance at lab meetings Wednesdays 4:30-5:30pm (mandatory)
- Running laboratory-, Zoom-, and computer-based data collection sessions
- “Coding” or systematically recording behavior from A/V records or other data

- Processing study data (e.g., transcription, data entry)
SPLAT Lab RAs also receive extensive career development support through discussions in lab meetings as well as direct mentoring by Dr. Shiota and the SPLAT Lab graduate students. Those who have completed at least one year of RA work are eligible for mentoring in an honors thesis or comparable year-long independent research project.
To apply for a Research Assistant position please email Jamie Katz at jkatz13@asu.edu.
The 4th edition of Emotion & Motivation, published by Oxford University Press, is now available! Previously titled Emotion, co-authored with the brilliant Jim Kalat, this new edition with co-author Sarah Rose Cavanagh merges the sciences of emotion, affect, and motivation. The text includes both classic and cutting-edge research, and encourages critical thinking by openly tackling ongoing controversies, contradictory findings, methodological limitations, and even replication failures in a balanced and constructive way. While highly rigorous, the text is also student-friendly, with a light, humorous tone. With real-world stories and an intuitive structure, Emotion and Motivation addresses questions undergraduates are most likely to ask: Why do we have emotions? How do they affect our lives? What motivates human behavior? How can we improve well-being? You can find the text at Amazon, as well as at the Oxford University Press website.
