Evaluating Team Formation Strategies With Algorithms, Ethan E. Lopez, Andy Vo

Student Scholar Symposium Abstracts and Posters

Effective teamwork is essential for collaborative learning, yet forming compatible student groups remains a persistent challenge. This study explores how algorithmic team-building methods influence students’ social and academic compatibility overtime. To support this investigation, we designed a visual survey system called “The Disco Ball." Evaluating work ethics, lifestyles, behaviors, and communication styles, students were initially assigned to project teams using one of three conditions: (1) random assignment (control), (2) a “most matches” condition maximizing similarity between students, and (3) a “diverse communication styles” condition designed to balance differing interaction preferences. After an initial collaboration period, students were given the opportunity …

A Multi-Measurement Study Of The Relation Between Deliberation And Volition, Guillaume P. Pech, Emilie A. Caspar, Elisabeth Pacherie, Axel Cleeremans, Uri Maoz

Psychology Faculty Articles and Research

Historically, voluntary action and volition more generally have been investigated through the lens of meaningless decisions. Importantly, these findings have been used in the debate about key notions like free will and moral responsibility. However, more recent claims have challenged the possibility of generalizing findings from a meaningless context to a more meaningful one. The current study investigates the markers of volition, specifically comparing meaningful and meaningless decisions. In an effort to maximize their monetary gain, 50 participants repeatedly deliberated between two options, making either rewarded choices—hard-deliberation decisions (where the options differed along two dimensions) or easy-deliberation decisions (where the …

The Impact Of Monetary Incentives On Delay Discounting Within A Year-Long Physical Activity Intervention, Vincent Berardi, Christine B. Phillips, Mindy L. Mcentee, Chad Stecher, Michael Todd, Marc A. Adams

Psychology Faculty Articles and Research

Background

Delay discounting is the depreciation in a reward’s perceived value as a function of the time until receipt. Monetary incentive programs that provide rewards contingent on meeting daily physical activity (PA) goals may change participants’ delay discounting preferences. Purpose

Determine if monetary incentives provided in close temporal proximity to meeting PA goals changed delay discounting, and if such changes mediated intervention effects. Methods

Inactive adults (n = 512) wore accelerometers during a 12-month intervention where they received proximal monetary incentives for meeting daily moderate-to-vigorous PA (MVPA) goals or delayed incentives for study participation. Delay discount rate and average …

Causal Inference In Psychology And Neuroscience: From Association To Causation, Dehua Liang

Computational and Data Sciences (PhD) Dissertations

In psychology and neuroscience, inferring causality in non-experimental studies is almost taboo, because data in these studies, e.g., survey data and resting-state neuroimaging data, are often contaminated by unmeasured confounders. Psychologists and neuroscientists are often cautious about their results, and reluctant to make false claims about causality in non-experimental studies. Therefore, they adopt less stringent statistical analysis techniques that can only infer associational relations. However, the ambiguity about causality in traditional statistical analysis creates much confusion in interpreting analytical results - some studies make implicit causal claims about their results using words such as “impacts”, “lead to” and “affects”. This …

Smart Homes For Smart Health: Developing An Interactive System To Reduce In-Home Secondhand Smoke, Christie Kika, Janice Han, Vincent Berardi

Student Scholar Symposium Abstracts and Posters

Smoke from any source is potentially harmful because it contains fine particulate matter that is associated with acute and chronic conditions. Second-hand smoke (SHS) is particularly unsafe for children due to biological characteristics (higher breathing rates, immature lungs and underdeveloped immune systems) that make it difficult to filter toxins.To address this concern, we recently completed Project Fresh Air (PFA), an NIH-funded R01 intervention that installed air particle sensors in the households of tobacco smokers who lived with children. The purpose of our research is to investigate and develop efficient smart home devices that monitor SHS in various living spaces to …

Healing Through Creativity And Creation: Drama Therapy As Treatment For Individuals With Eating Disorders, Hayley Werner

Student Scholar Symposium Abstracts and Posters

For those living with eating disorders, intervention and effective treatment can mean the difference between life and death. Conventional treatments, such as Cognitive Behavioral Therapy and Dialectical Behavioral Therapy, forms of talk therapy, and Nutritional Counseling, focus solely on the psychological patterns or nutritional science of eating disorders. Though these treatments are effective for some individuals, there is a gap in treatment options that address both the mind and body as one and appeal to the humanity of patients outside of their disorder(s). Herein lies the power and potential of integrating drama therapy as a widely available treatment. Drama therapy …

An Integration-To-Bound Model Of Decision-Making That Accounts For The Spectral Properties Of Neural Data, Ramón Guevara Erra, Marco Arbotto, Aaron Schurger

Psychology Faculty Articles and Research

Integration-to-bound models are among the most widely used models of perceptual decision-making due to their simplicity and power in accounting for behavioral and neurophysiological data. They involve temporal integration over an input signal (“evidence”) plus Gaussian white noise. However, brain data shows that noise in the brain is long-term correlated, with a spectral density of the form 1/fα (with typically 1 < α < 2), also known as pink noise or ‘1/f’ noise. Surprisingly, the adequacy of the spectral properties of drift-diffusion models to electrophysiological data has received little attention in the literature. Here we propose a model of accumulation of evidence for decision-making that takes into consideration the spectral properties of brain signals. We develop a generalization of the leaky stochastic accumulator model using a Langevin equation whose non-linear noise term allows for varying levels of autocorrelation in the time course of the decision variable. We derive this equation directly from magnetoencephalographic data recorded while subjects performed a spontaneous movement initiation task. We then propose a nonlinear model of accumulation of evidence that accounts for the ‘1/f’ spectral properties of brain signals, and the observed variability in the power spectral properties of brain signals. Furthermore, our model outperforms the standard drift-diffusion model at approximating the empirical waiting time distribution.

Computational Model For Behavior Shaping As An Adaptive Health Intervention Strategy, Vincent Berardi, Ricardo Carretero-González, Neil E. Klepeis, Sahar Ghanipoor Machiani, Arash Jahangiri, John Bellettiere, Melbourne Hovell

Psychology Faculty Articles and Research

Adaptive behavioral interventions that automatically adjust in real-time to participants’ changing behavior, environmental contexts, and individual history are becoming more feasible as the use of real-time sensing technology expands. This development is expected to improve shortcomings associated with traditional behavioral interventions, such as the reliance on imprecise intervention procedures and limited/short-lived effects. JITAI adaptation strategies often lack a theoretical foundation. Increasing the theoretical fidelity of a trial has been shown to increase effectiveness. This research explores the use of shaping, a well-known process from behavioral theory for engendering or maintaining a target behavior, as a JITAI adaptation strategy. A computational …

Individualism, Collectivism, And Trade, Aidin Hajikhameneh, Erik O. Kimbrough

Economics Faculty Articles and Research

While economists recognize the important role of formal institutions in the promotion of trade, there is increasing agreement that institutions are typically endogenous to culture, making it difficult to disentangle their separate contributions. Lab experiments that assign institutions exogenously and measure and control individual cultural characteristics can allow for clean identification of the effects of institutions, conditional on culture, and help us understand the relationship between behavior and culture, under a given institutional framework. We focus on cultural tendencies toward individualism/collectivism, which social psychologists highlight as an important determinant of many behavioral differences across groups and people. We design an …

Volition And Action In The Human Brain: Processes, Pathologies, And Reasons, Itzhak Fried, Patrick Haggard, Biyu J. He, Aaron Schurger

Psychology Faculty Articles and Research

Humans seem to decide for themselves what to do, and when to do it. This distinctive capacity may emerge from an ability, shared with other animals, to make decisions for action that are related to future goals, or at least free from the constraints of immediate environmental inputs. Studying such volitional acts proves a major challenge for neuroscience. This review highlights key mechanisms in the generation of voluntary, as opposed to stimulus-driven actions, and highlights three issues. The first part focuses on the apparent spontaneity of voluntary action. The second part focuses on one of the most distinctive, but elusive, …

Entrainment Of Voluntary Movement To Undetected Auditory Regularities, Aaron Schurger, Nathan Faivre, Leila Cammoun, Bianca Trovó, Olaf Blanke

Psychology Faculty Articles and Research

In physics “entrainment” refers to the synchronization of two coupled oscillators with similar fundamental frequencies. In behavioral science, entrainment refers to the tendency of humans to synchronize their movements with rhythmic stimuli. Here, we asked whether human subjects performing a tapping task would entrain their tapping to an undetected auditory rhythm surreptitiously introduced in the guise of ambient background noise in the room. Subjects performed two different tasks, one in which they tapped their finger at a steady rate of their own choosing and one in which they performed a single abrupt finger tap on each trial after a delay …

An Evaluation Of The Effects Of Intensity And Duration On Outcomes Across Treatment Domains For Children With Autism Spectrum Disorder, Erik J. Linstead, D. R. Dixon, E. Hong, C. O. Burns, Ryan French, M. N. Novack, D. Granpeesheh

Mathematics, Physics, and Computer Science Faculty Articles and Research

Applied behavior analysis (ABA) is considered an effective treatment for individuals with autism spectrum disorder (ASD), and many researchers have further investigated factors associated with treatment outcomes. However, few studies have focused on whether treatment intensity and duration have differential influences on separate skills. The aim of the current study was to investigate how treatment intensity and duration impact learning across different treatment domains, including academic, adaptive, cognitive, executive function, language, motor, play, and social. Separate multiple linear regression analyses were used to evaluate these relationships. Participants included 1468 children with ASD, ages 18 months to 12 years old, M= …

Temperament Factors And Dimensional, Latent Bifactor Models Of Child Psychopathology: Transdiagnostic And Specific Associations In Two Youth Samples, Benjamin L. Hankin, Elyssia Poggi Davis, Hannah Snyder, Jami F. Young, Laura M. Glynn, Curt A. Sandman

Psychology Faculty Articles and Research

Common emotional and behavioral symptoms co-occur and are associated with core temperament factors. This study investigated links between temperament and dimensional, latent psychopathology factors, including a general common psychopathology factor (p factor) and specific latent internalizing and externalizing liabilities, as captured by a bifactor model, in two independent samples of youth. Specifically, we tested the hypothesis that temperament factors of negative affectivity (NA), positive affectivity (PA), and effortful control (EC) could serve as both transdiagnostic and specific risks in relation to recent bifactor models of child psychopathology. Sample 1 included 571 youth (average age 13.6, SD = 2.37, range 9.3–17.5) …

Increasing Valued Behaviors Precedes Reduction In Suffering: Findings From A Randomized Controlled Trial Using Act, Andrew T. Gloster, Jens Klotsche, Joseph Ciarrochi, Georg Eifert, Rainer Sonntag, Hans-Ulrich Wittchen, Jürgen Hoyer

Psychology Faculty Articles and Research

Background: Psychological flexibility theory (PFT) suggests three key processes of change: increases in value-directed behaviors, reduction in struggle with symptoms, and reduction in suffering. We hypothesized that Acceptance and Commitment Therapy (ACT) would change these processes and that increases in valued action and decreases in struggle would precede change in suffering.

Method: Data were derived from a randomized clinical trial testing ACT (vs. waitlist) for treatment-resistant patients with primary panic disorder with/without agoraphobia (n= 41). Valued behavior, struggle, and suffering were assessed at each of eight sessions.

Results: Valued actions, struggle, and suffering all changed over the …

Angels And Demons: Using Behavioral Types In A Real-Effort Moral Dilemma To Identify Expert Traits, Hernan Bejarano, Ellen P. Green, Stephen Rassenti

ESI Publications

In this article, we explore how independently reported measures of subjects' cognitive capabilities, preferences, and sociodemographic characteristics relate to their behavior in a real-effort moral dilemma experiment. To do this, we use a unique dataset, the Chapman Preferences and Characteristics Instrument Set (CPCIS), which contains over 30 standardized measures of preferences and characteristics. We find that simple correlation analysis provides an incomplete picture of how individual measures relate to behavior. In contrast, clustering subjects into groups based on observed behavior in the real-effort task reveals important systematic differences in individual characteristics across groups. However, while we find more differences, these …

Too Much Of A Good Thing? Overexertion Of Self-Control And Dietary Adherence In Individuals With Type 2 Diabetes, Brooke N. Jenkins, Karen S. Rook, Raquel Borges-Garcia, Melissa M. Franks, Mary Ann Parris Stephens

Psychology Faculty Articles and Research

Objectives

The resource model of self‐control posits that self‐control is a finite resource that can be depleted. Individuals with diabetes must continually restrict their diet, requiring self‐control. As a result, dietary adherence is difficult, and lapses are common. People with diabetes who overexert self‐control following a lapse may be especially likely to experience a subsequent relapse, as suggested by the resource model. This investigation used the resource model of self‐control to test whether overexertion of dietary self‐control following a lapse would be predictive of a subsequent relapse in dietary control.

Design

We tested this prediction in a daily diary study …

Least Among Brethren, Dami Onifade

Student Scholar Symposium Abstracts and Posters

I was in the second row of Dr. Jules Herrell’s psychology class on a brisk day in Washington DC when I heard about the prison experiment at Stanford University during a college lecture. Naturally, I was shocked to learn young men my age that had gone in as equals could turn on each other for a meager salary and free meals. I wanted to show this quality of people in situations involving intimidation, peer pressure and envy. My co-writers and I found a way into the narrative through the bond of two friends, Prince and Malachi. This allowed us a …

Paradoxical Interaction Between Ocular Activity, Perception, And Decision Confidence At The Threshold Of Vision, Aaron Schurger

Psychology Faculty Articles and Research

In humans and some other species perceptual decision-making is complemented by the ability to make confidence judgements about the certainty of sensory evidence. While both forms of decision process have been studied empirically, the precise relationship between them remains poorly understood. We performed an experiment that combined a perceptual decision-making task (identifying the category of a faint visual stimulus) with a confidence-judgement task (wagering on the accuracy of each perceptual decision). The visual stimulation paradigm required steady fixation, so we used eye-tracking to control for stray eye movements. Our data analyses revealed an unexpected and counterintuitive interaction between the steadiness …

The Role Of Self‐Injury In The Organisation Of Behaviour, Curt A. Sandman, Aaron S. Kemp, Christopher Mabini, David Pincus, Magnus Magnusson

Psychology Faculty Articles and Research

Background—Self-injuring acts are among the most dramatic behaviours exhibited by human beings. There is no known single cause and there is no universally agreed upon treatment. Sophisticated sequential and temporal analysis of behaviour has provided alternative descriptions of self-injury that provide new insights into its initiation and maintenance.

Method—Forty hours of observations for each of 32 participants were collected in a contiguous two-week period. Twenty categories of behavioural and environmental events were recorded electronically that captured the precise time each observation occurred. Temporal behavioural/ environmental patterns associated with self-injurious events were revealed with a method (tpatterns; THEME) for …

Becoming Happier Takes Both A Will And A Proper Way: An Experimental Longitudinal Intervention To Boost Well-Being, Sonja Lyubomirsky, Rene Dickerhoof, Julia K. Boehm, Kennon M. Sheldon

Psychology Faculty Articles and Research

An 8-month-long experimental study examined the immediate and longer term effects of regularly practicing two assigned positive activities (expressing optimism and gratitude) on well-being. More important, this intervention allowed us to explore the impact of two metafactors that are likely to influence the success of any positive activity: whether one self-selects into the study knowing that it is about increasing happiness and whether one invests effort into the activity over time. Our results indicate that initial self-selection makes a difference, but only in the two positive activity conditions, not the control, and that continued effort also makes a difference, but, …
