Is Postpartum Depression A Disease Of Modern Civilization?, Jennifer Hahn-Holbrook, Martie Haselton

Psychology Faculty Articles and Research

Access to calorie-dense foods, medicine, and other comforts has made modern humans healthier than our prehistoric ancestors in many respects. However, the epidemics of obesity, diabetes, and cardiovascular disease suggest that there are also drawbacks to modern living. Here, we address the question of whether the dramatic cultural changes that have occurred over the past century have inflated rates of postpartum depression, adding postpartum depression to the list of diseases of modern civilization. We review evidence from cross-cultural, epidemiological, and experimental studies documenting associations between postpartum depression and modern patterns of early weaning, diets deficient in essential fatty acids, low …

“Me & My Brain”: Exposing NeuroscienceʼS Closet Dualism, Liad Mudrik, Uri Maoz

Psychology Faculty Articles and Research

Our intuitive concept of the relations between brain and mind is increasingly challenged by the scientific world view. Yet, although few neuroscientists openly endorse Cartesian dualism, careful reading reveals dualistic intuitions in prominent neuroscientific texts. Here, we present the “double-subject fallacy”: treating the brain and the entire person as two independent subjects who can simultaneously occupy divergent psychological states and even have complex interactions with each other—as in “my brain knew before I did.” Although at first, such writing may appear like harmless, or even cute, shorthand, a closer look suggests that it can be seriously misleading. Surprisingly, this confused …

Intentions And Voluntary Actions: Reframing The Problem, Aaron Schurger

Psychology Faculty Articles and Research

Nachev and Hacker are justified in drawing our attention to the importance of conceptual clarity and coherence as these are too often overshadowed by technical sophistication and methodological rigor, which by themselves count for little. But can a process of “conceptual analysis” actually help us to avoid pitfalls, or does it merely serve to expose those pitfalls in hindsight? What is needed is a method for making scientific arguments formulaic and laying bare the implicit assumptions. We have tools for this, but not everyone uses them.

Development Of A Short Version Of The Modified Yale Preoperative Anxiety Scale, Brooke N. Jenkins, Michelle Fortier, Sherrie H. Kaplan, Linda C. Mayes, Zeev N. Kain

Psychology Faculty Articles and Research

BACKGROUND: The modified Yale Preoperative Anxiety Scale (mYPAS) is the current “criterion standard” for assessing child anxiety during induction of anesthesia and has been used in >100 studies. This observational instrument covers 5 items and is typically administered at 4 perioperative time points. Application of this complex instrument in busy operating room (OR) settings, however, presents a challenge. In this investigation, we examined whether the instrument could be modified and made easier to use in OR settings.

METHODS: This study used qualitative methods, principal component analyses, Cronbach αs, and effect sizes to create the mYPAS-Short Form (mYPAS-SF) and reduce time …

Pregnancy Anxiety And Prenatal Cortisol Trajectories, Heidi S. Kane, Christine Dunkel Schetter, Laura M. Glynn, Calvin J. Hobel, Curt A. Sandman

Psychology Faculty Articles and Research

Pregnancy anxiety is a potent predictor of adverse birth and infant outcomes. The goal of the current study was to examine one potential mechanism whereby these effects may occur by testing associations between pregnancy anxiety and maternal salivary cortisol on 4 occasions during pregnancy in a sample of 448 women. Higher mean levels of pregnancy anxiety over the course of pregnancy predicted steeper increases in cortisol trajectories compared to lower pregnancy anxiety. Significant differences between cortisol trajectories emerged between 30 to 31 weeks of gestation. Results remained significant when adjusted for state anxiety and perceived stress. Neither changes in pregnancy …

Two Distinct Dynamic Modes Subtend The Detection Of Unexpected Sounds, Jean-Rémi King, Alexandre Gramfort, Aaron Schurger, Lionel Naccache, Stanislas Dehaene

Psychology Faculty Articles and Research

The brain response to auditory novelty comprises two main EEG components: an early mismatch negativity and a late P300. Whereas the former has been proposed to reflect a prediction error, the latter is often associated with working memory updating. Interestingly, these two proposals predict fundamentally different dynamics: prediction errors are thought to propagate serially through several distinct brain areas, while working memory supposes that activity is sustained over time within a stable set of brain areas. Here we test this temporal dissociation by showing how the generalization of brain activity patterns across time can characterize the dynamics of the underlying …

Predeliberation Activity In Prefrontal Cortex And Striatum And The Prediction Of Subsequent Value Judgment, Uri Maoz, Ueli Rutishauser, Soyoun Kim, Xinying Cai, Christof Koch

Psychology Faculty Articles and Research

Rational, value-based decision-making mandates selecting the option with highest subjective expected value after appropriate deliberation. We examined activity in the dorsolateral prefrontal cortex (DLPFC) and striatum of monkeys deciding between smaller, immediate rewards and larger, delayed ones. We previously found neurons that modulated their activity in this task according to the animal's choice, while it deliberated (choice neurons). Here we found neurons whose spiking activities were predictive of the spatial location of the selected target (spatial-bias neurons) or the size of the chosen reward (reward-bias neurons) before the onset of the cue presenting the decision-alternatives, and thus before rational deliberation …

Reducing Multi-Sensor Data To A Single Time Course That Reveals Experimental Effects, Aaron Schurger, Sebastien Marti, Stanislas Dehaene

Psychology Faculty Articles and Research

Background: Multi-sensor technologies such as EEG, MEG, and ECoG result in high-dimensional data sets. Given the high temporal resolution of such techniques, scientific questions very often focus on the time-course of an experimental effect. In many studies, researchers focus on a single sensor or the average over a subset of sensors covering a “region of interest” (ROI). However, single-sensor or ROI analyses ignore the fact that the spatial focus of activity is constantly changing, and fail to make full use of the information distributed over the sensor array.

Methods: We describe a technique that exploits the optimality and …

Single-Trial Decoding Of Auditory Novelty Responses Facilitates The Detection Of Residual Consciousness, J. R. King, F. Faugeras, A. Gramfort, Aaron Schurger, I. El Karoui, J. D. Sitt, B. Rohaut, C. Wacongne, E. Labyt, T. Bekinschtein, L. Cohen, L. Naccache, S. Dehaene

Psychology Faculty Articles and Research

Detecting residual consciousness in unresponsive patients is a major clinical concern and a challenge for theoretical neuroscience. To tackle this issue, we recently designed a paradigm that dissociates two electro-encephalographic (EEG) responses to auditory novelty. Whereas a local change in pitch automatically elicits a mismatch negativity (MMN), a change in global sound sequence leads to a late P300b response. The latter component is thought to be present only when subjects consciously perceive the global novelty. Unfortunately, it can be difficult to detect because individual variability is high, especially in clinical recordings. Here, we show that multivariate pattern classifiers can extract …

Relation Between Optimism And Lipids In Midlife, Julia K. Boehm, David R. Williams, Eric B. Rimm, Carol Ryff, Laura D. Kubzansky

Psychology Faculty Articles and Research

This research examined optimism’s relationship with total cholesterol, high density lipoprotein (HDL) cholesterol, low density lipoprotein (LDL) cholesterol, and triglycerides. The hypothesis that optimism is associated with a healthier lipid profile was tested. Participants were 990 mostly white men and women from the Midlife in the United States study who were on average 55.1 years old. Optimism was assessed by self-report with the Life Orientation Test. A fasting blood sample was used to assess serum lipid levels. Linear and logistic regression models examined the cross-sectional association between optimism and lipids accounting for covariates such as demographic characteristics (e.g., education) and …

Randomized Clinical Trial Of Cognitive Behavioral Therapy (Cbt) Versus Acceptance And Commitment Therapy (Act) For Mixed Anxiety Disorders, Joanna Arch, Georg Eifert, Carolyn Davies, Jennifer C. Plumb Vilardaga, Raphael D. Rose, Michael G. Craske

Psychology Faculty Articles and Research

Objective—Randomized comparisons of acceptance-based treatments with traditional cognitive behavioral therapy (CBT) for anxiety disorders are lacking. To address this research gap, we compared acceptance and commitment therapy (ACT) to CBT for heterogeneous anxiety disorders.

Method—One hundred twenty eight individuals (52% female, mean age = 38, 33% minority) with one or more DSM-IV anxiety disorders began treatment following randomization to 12 sessions of CBT or ACT; both treatments included behavioral exposure. Assessments at pre-treatment, post-treatment, 6-month, and 12-month follow-up measured anxiety specific (principal disorder Clinical Severity Ratings [CSR], Anxiety Sensitivity Index, Penn State Worry Questionnaire, Fear Questionnaire avoidance) and …

A Prospective Study Of Positive Psychological Well-Being And Coronary Heart Disease, Julia K. Boehm, Christopher Peterson, Mika Kivimaki, Laura D. Kubzansky

Psychology Faculty Articles and Research

Objective: Research suggests that positive psychological well-being is associated with cardiovascular health. However, much of this research uses elderly samples and has not determined the pathways by which psychological well-being influences cardiovascular disease or whether effects are similar for men and women. This study investigates the association between two aspects of well-being (emotional vitality and optimism) and coronary heart disease (CHD) in a sample of middle-aged men and women, and considers potential mediating factors.

Method: Between 1991 and 1994, well-being and coronary risk factors were assessed among 7,942 individuals without a prior cardiovascular event from the Whitehall II …

Development Of A Positive Psychology Intervention For Patients With Acute Cardiovascular Disease, Jeff C. Huffman, Carol A. Mastromauro, Julia K. Boehm, Rita Seabrook, Gregory L. Fricchione, John W. Denninger, Sonja Lyubomirsky

Psychology Faculty Articles and Research

The management of depression and other negative psychological states in cardiac patients has been a focus of multiple treatment trials, though such trials have not led to substantial improvements in cardiac outcomes. In contrast, there has been minimal focus on interventions to increase positive psychological states in cardiac patients, despite the fact that optimism and other positive states have been associated with superior cardiovascular outcomes. Our objective was to develop an 8-week, phone-based positive psychology intervention for patients hospitalized with acute cardiac disease (acute coronary syndrome or decompensated heart failure). Such an intervention would consist of positive psychology exercises adapted …

David Grove's Metaphors For Healing, David Pincus, Anees A. Sheikh

Psychology Faculty Articles and Research

Within the ever-expanding list of approaches to psychotherapy, there is a tendency to overlook deep imagery approaches. The current article reports on one such metaphor-based therapy developed by David Grove (Grove & Panzer, 1989). The approach is analyzed within the context of mainstream contemporary psychotherapy in general, the state of empirical understanding of common processes to psychotherapy, and in relation to other deep imagery-based approaches to therapy. Next, a step-by-step description of the techniques used within metaphor therapy are presented, along with a case example demonstrating the use of these techniques on a case involving pain symptoms. Finally, it is …

Functionality, Parsimony, Discovery, Avoiding Hamartia: How Evolutionary Perspectives Are Changing Psychology, Brooke N. Jenkins, Aaron T. Goetz

Psychology Faculty Articles and Research

Evolutionary psychology offers an important perspective to scientific psychology. Evolutionary psychology, in its short existence, has added an abundance of knowledge to the social sciences, let alone psychology. The study of human cognition and behavior remains incomplete without an evolutionary perspective. Here, we argue that evolutionary psychology uniquely provides a complete understanding of scientific psychology because it explains the functions of our psychological traits, provides us with the most parsimonious explanation of many psychological phenomena, predicts undocumented phenomena, and possibly allows us to avoid the downfalls of some of our contemptible evolved psychological mechanisms.

Nonlinear Dynamics And Interpersonal Correlates Of Verbal Turn-Taking Patterns In A Group Therapy Session, David Pincus, Stephen J. Guastello

Psychology Faculty Articles and Research

Interpersonal processes and dynamics are ubiquitous topics in psychotherapy, yet they are difficult to study and are theoretically fragmented across therapeutic subdisciplines. The current study tests an integrative model of interpersonal dynamics in small groups using nonlinear dynamical systems theory. The conversation of one group therapy session (with six adolescent sex offenders) is analyzed using orbital decomposition, which allows for the identification of patterns in categorical time series data. The results show evidence of selforganizing social patterns, based on formal measures of turbulence (Lyapunov dimension), information novelty (Shannon's entropy), and complexity (fractal dimension). The degree of patterning in turn taking …
