A year in the social life of a teenager: Within-person fluctuations in stress, phone communication, and anxiety and depression. Clinical Psychological Science.Abstract
Stressful life events (SLEs) are strongly associated with the emergence of adolescent anxiety and depression, but the underlying mechanisms remain poorly understood, especially at the within-person level. We investigated how adolescent social communication (i.e., frequency of calls and texts) following SLEs relates to changes ininternalizingsymptomsin a multi-timescale intensive year-long study (N=30; n=355 monthly observations; n=~5,000 experience-sampling observations). Within-person increases in SLEs were associated with receiving more calls than usual at both monthly-and momentary-levels, and making more calls at the monthly-level. Increased calls were prospectively associated with worsening internalizing symptoms at the monthly-level only, suggesting that SLEs rapidly influences phone communicationpatterns, but these communication changes may have a more protracted, cumulative influence on internalizing symptoms. Finally, increased incoming calls prospectively mediated the association between SLEs and anxiety at the monthly-level.We identify adolescent social communication fluctuations as a potential mechanism conferring risk for stress-related internalizing psychopathology
Nook, E. C., Flournoy, J. C., Rodman, A. M., Mair, P., & McLaughlin, K. A. (In Press). High emotion differentiation buffers against internalizing symptoms following exposure to stressful life events in adolescence: An intensive longitudinal study. Clinical Psychological Science. Publisher's VersionAbstract
Exposure to stressful life events is strongly associated with internalizing psychopathology, and identifying factors that reduce vulnerability to stress-related internalizing problems is critical for development of early interventions. Drawing on research from affective science, we tested whether high emotion differentiation—the ability to specifically identify one’s feelings—buffers adolescents from developing internalizing symptoms when exposed to stress. Thirty adolescents completed a laboratory measure of emotion differentiation before an intensive year-long longitudinal study in which exposure to stress and internalizing problems were assessed at both the moment-level (n=4,921 experience sampling assessments) and monthly-level (n=355 monthly assessments). High negative and positive emotion differentiation attenuated moment-level coupling between perceived stress and feelings of depression, and high negative emotion differentiation eliminated monthly-level associations between stressful life events and anxiety symptoms. These results suggest that high emotion differentiation buffers adolescents against anxiety and depression in the face of stress, perhaps by facilitating adaptive emotion regulation.

Friends and therapists often encourage people in distress to say how they feel (i.e., name their emotions) with the hope that identifying their emotions will help them cope. Although lay and some psychological theories posit that emotion naming should facilitate subsequent emotion regulation, there is little research directly testing this question. Here, we report on two experimental studies that test how naming the emotions evoked by aversive images impacts subsequent regulation of those emotions. In Study 1 (N = 80), participants were randomly assigned into one of four between-subjects conditions in which they either (i) passively observed aversive images, (ii) named the emotions that these images made them feel, (iii) regulated their emotions by reappraising the meaning of images, or (iv) both named and regulated their emotions. Analyses of self-reported negative affect revealed that emotion naming impeded emotion regulation via reappraisal. Participants who named their emotions before reappraising reported feeling worse than those who regulated without naming. Study 2 (N = 60) replicated these findings in a within-participants design, demonstrated that emotion naming also impeded regulation via mindful acceptance, and showed that observed effects were unrelated to a measure of social desirability, thereby mitigating the concern of experimenter demand. Together, these studies show that the impact of emotion naming on emotion regulation opposes common intuitions: Instead of facilitating emotion regulation via reappraisal or acceptance, constructing an instance of a specific emotion category by giving it a name may “crystalize” one’s affective experience and make it more resistant to modification.

Developmental variation in the associations of attention bias to emotion with internalizing and externalizing psychopathology. Research on Child and Adolescent Psychopathology , 49, 711–726. Publisher's VersionAbstract
Attention biases to emotion are associated with symptoms of internalizing and externalizing psychopathology in children and adolescents. It is unknown whether attention biases to emotion and their associations with different symptoms of psychopathology vary across development from early childhood through young adulthood. We examine this age-related variation in the current study. Participants (N = 190; ages: 4-25) completed survey-based psychopathology symptom measures and a dot-probe task to assess attention bias to happy, sad, and angry relative to neutral faces. We tested whether linear or non-linear (e.g., spline-based models) associations best characterized age-related variation in attention to emotion. We additionally examined whether attention biases were associated with depression, anxiety, and externalizing symptoms and whether these associations varied by age. No age-related differences in attention biases were found for any of the emotional faces. Attention biases were associated with psychopathology symptoms, but only when examining moderation by age. Biased attention to angry faces was associated with greater symptoms of anxiety and depression in adolescents and young adults, but not children. Similarly, biased attention to happy faces was associated with externalizing symptoms in adolescents and young adults, but not in children. In contrast, biased attention to happy faces was associated with greater anxiety symptoms in children, but not in adolescents or young adults. Biased attention toward social threat and reward becomes more strongly coupled with internalizing and externalizing symptoms, respectively, during the transition to adolescence. These findings could inform when interventions such as attention bias modification training may be most effective.

Although common sense suggests that we are motivated to pursue positive and avoid negative experiences, previous research shows that people regularly seek out negative experiences. In the current study, we characterized this tendency from childhood to young adulthood. Due to the known increases in risky behavior and sensation seeking in adolescence, we hypothesized that adolescents would show an increased engagement with negatively valenced stimuli compared to children and adults. Participants aged 4-25 (N=192) completed a behavioral task assessing motivation to engage with negative, positive, and neutral images. On each trial, participants viewed two small images and selected one to view at a larger size for up to 10s. Trials were organized into three valence conditions: negative versus positive images (matched on arousal), negative versus neutral images, and positive versus neutral images. Although participants chose positive images more than neutral or negative images, participants selected negative images frequently, even when given a positive (28% of trials) or neutral (42% of trials) alternative. Contrary to expectations, the tendency to choose negative images was highest in early childhood and decreased linearly with increasing age, and the tendency to choose positive images increased linearly with age. These results provide insight into how motivation to engage with emotional stimuli varies across age. It is possible that the novelty and rarity of negative experiences drives children to pursue these stimuli. Alternatively, children may find negative images less aversive, which would caution against assuming that these stimuli elicit the same motivational states in individuals of all ages.

The ability to identify and label one’s emotions is associated with effective emotion regulation, rendering emotional awareness important for mental health. We evaluated how emotional awareness was related to psychopathology and whether low emotional awareness was a transdiagnostic mechanism explaining the increase in psychopathology during the transition to adolescence and as a function of childhood trauma—specifically violence exposure. In Study 1, children and adolescents (N=120, aged 7-19 years) reported on emotional awareness and
psychopathology. Emotional awareness was negatively associated with psychopathology (pfactor) and worsened across age in females but not males. In Study 2 (N=262, aged 8-16 years), we replicated these findings and demonstrated longitudinally that low emotional awareness mediated increases in p-factor as a function of age in females and violence exposure. These findings indicate that low emotional awareness may be a transdiagnostic mechanism linking adolescent development, sex, and trauma with the emergence of psychopathology.

Charting the development of emotion comprehension and abstraction from childhood to adulthood using observer-rated and linguistic measures. Emotion , 20 (5), 773-792. Publisher's VersionAbstract
This study examined two facets of emotion development: emotion word comprehension (knowing the meaning of emotion words such as "anger" or "excitement") and emotion concept abstraction (representing emotions in terms of internal psychological states that generalize across situations). Using a novel emotion vocabulary assessment, we captured how a cross-sectional sample of participants aged 4-25 ( = 196) defined 24 emotions. Smoothing spline regression models suggested that emotion comprehension followed an emergent shape: Knowledge of emotion words increased across childhood and plateaued around age 11. Human coders rated the abstractness of participants' responses, and these ratings also followed an emergent shape but plateaued significantly later than comprehension, around age 18. An automated linguistic analysis of abstractness supported coders' perceptions of increased abstractness across age. Finally, coders assessed the definitional strategies participants used to describe emotions. Young children tended to describe emotions using strategies such as providing example situations that evoked those emotions or by referring to physiological markers of emotional experiences. Whereas use of these concrete strategies decreased with age, the tendency to use more strategies such as providing general definitions that delineated the causes and characteristics of emotions or by providing synonyms of emotion words increased with age. Overall, this work (a) provides a tool for assessing definitions of emotion terms, (b) demonstrates that emotion concept abstraction increases across age, and (c) suggests that adolescence is a period in which emotion words are comprehended but their level of abstraction continues to mature.

Regulating one's emotions is an important psychological skill at all ages. Cognitive reappraisal-changing the meaning of a stimulus to alter its emotional impact-is an effective emotion regulation technique. Prior work shows that adults spontaneously reduce their use of present tense verbs and first-person singular pronouns (e.g., ) when engaging in cognitive reappraisal, a linguistic shift that is thought to track increased psychological distance. Here, we investigated whether such during emotion regulation varied across age. Participants aged 10 to 23 (N = 112) spoke aloud their thoughts and feelings while completing a classic cognitive reappraisal task. Participants' verbal responses were recorded, transcribed, and analyzed for linguistic distancing, compliance with reappraisal instructions, and use of 8 different reappraisal strategies identified by prior researchers. Results replicated prior work in a developmental sample: Reappraisal decreased negative affect and increased linguistic distancing, and stronger linguistic distancing during reappraisal was associated with more successful emotion regulation. Contrary to hypotheses, we found no age differences in linguistic distancing or reappraisal success, even after excluding trials on which participants did not comply with reappraisal instructions. However, reappraisal strategy use varied across age. Use of the and (i.e., ) strategies increased across age whereas use decreased across age. Additionally, in adolescence, use was elevated and use was reduced compared to other ages. Results suggest that linguistic distancing during emotion regulation is stable from age 10 to 23 but use of cognitive reappraisal strategies differs.

In rapidly changing environments, humans and other animals often glean information about the value of objects and behaviors through social learning. For example, in humans, observing others’ behaviors and their consequences enables the transmission of a wide range of information about what stimuli should be avoided and approached, and what behaviors are useful to that end. We survey important developments in our understanding of the behavioral, computational, and neural aspects of social learning of threat and safety. In particular, we discuss the study of social learning through observation, which has enabled comparisons across species. This research shows that observational threat and safety learning draw on mechanisms partially shared with direct (Pavlovian) threat conditioning and extinction learning. Importantly, however, social and asocial learning also differ from each other, for instance in the role that empathic processes play in observational but not asocial learning. We conclude by underscoring the importance of studying social learning across species using behavioral, computational, and neural measures.

Language is known to play an important role in communicating our thoughts, memories, and emotions. In this chapter, we propose that the role of language extends much more deeply to   further shape and constitutively create these mental phenomena. Research on emotion has shown that language can powerfully influence experiences and perceptions that are affective or emotional. Research on memory, too, has also shown that language can be used to shape and even create experiences of memory. We organize this work in a framework that is characterized by the many forms and aspects that language may take such as rich narratives, specific emotion words, words that focus on the situation v. words that focus on the body, and even words that convey psychological distance from grammatical tense and pronoun usage. We describe a constructionist theoretical model to understand how language shapes emotion and memory in terms of psychological and neural mechanisms. Our model integrates with recent active inference models of neural processing. Finally, we relate this work to clinical and translational models of therapeutic change.

OBJECTIVE: Self-injurious thoughts and behaviors (SITBs) are a complex and enduring public health concern. Increasingly, teenagers use digital platforms to communicate about a range of mental health topics. These discussions may provide valuable information that can lead to insights about complex issues like SITBs. However, the field of clinical psychology currently lacks an easy-to-implement toolkit that can quickly gather information about SITBs from online sources. In the present study, we applied topic modeling, a natural language processing technique, to identify SITBs and related themes online, and we validated this approach using human coders. METHOD: We separately used topic modeling software and human coders to identify themes present in text from a popular online Internet support forum for teenagers. We then determined the degree to which results from the software's topic model aligned with themes identified by human coders. RESULTS: We found that topic modeling detected SITBs and related themes in online discussions in a way that accurately distinguishes between relevant and irrelevant human-coded themes. CONCLUSIONS: This approach has the potential to drastically increase our understanding of SITBs and related issues discussed on digital platforms, as well as our ability to identify those at risk for such outcomes.

Emotion concepts are the internally held representations of what defines any given emotion. Contemporary emotion theories posit that emotion concepts occupy a central role in shaping our perceptions and experiences of emotion. However, like other concepts, emotion concepts actively change over the lifecourse. Here we review classic and contemporary ideas, and recent empirical research, that concern how emotion concepts develop from childhood to adulthood. Emerging evidence suggests that emotion concepts change in complex ways across early life development, which has a tangible impact on the emotional experiences of children, adolescents, and adults. Charting emotion concept development in this way holds implications for basic theories of emotion and development as well as more clinical theories focused on helping children and adolescents overcome emotion-regulatory challenges.

People differ in how specifically they separate affective experiences into different emotion types-a skill called emotion differentiation or emotional granularity. Although increased emotion differentiation has been associated with positive mental health outcomes, little is known about its development. Participants ( N = 143) between the ages of 5 and 25 years completed a laboratory measure of negative emotion differentiation in which they rated how much a series of aversive images made them feel angry, disgusted, sad, scared, and upset. Emotion-differentiation scores were computed using intraclass correlations. Emotion differentiation followed a nonlinear developmental trajectory: It fell from childhood to adolescence and rose from adolescence to adulthood. Mediation analyses suggested that an increased tendency to report feeling emotions one at a time explained elevated emotion differentiation in childhood. Importantly, two other mediators (intensity of emotional experiences and scale use) did not explain this developmental trend. Hence, low emotion differentiation in adolescence may arise because adolescents have little experience conceptualizing co-occurring emotions.

Weak dorsolateral prefrontal response to social criticism predicts worsened mood and symptoms following social conflict in people at familial risk for schizophrenia. Neuroimage Clinical , 18, 40-50. Publisher's VersionAbstract
Understanding the specific mechanisms that explain why people who have relatives with schizophrenia (i.e., people at familial high risk; FHR) are more likely to develop the disorder is crucial for prevention. We investigated a diathesis-stress model of familial risk by testing whether FHR individuals under-recruit brain regions central to emotion regulation when exposed to social conflict, resulting in worse mood and symptoms following conflict. FHR and non-FHR participants listened to critical, neutral, and praising comments in an fMRI scanner before completing 4 weeks of daily-diary records. Compared to non-FHR individuals, FHR individuals under-recruited the bilateral dorsolateral prefrontal cortex (DLPFC)-a region strongly implicated in cognitive emotion regulation-following criticism. Furthermore, within FHR participants, weak DLPFC response to criticism in the laboratory task was associated with elevated negative mood and positive symptoms on days with distressing social conflicts in daily-diary assessments. Results extend diathesis-stress models of schizophrenia by clarifying neural and environmental pathways to dysregulation in FHR individuals.

How do people represent their own and others' emotional experiences? Contemporary emotion theories and growing evidence suggest that the conceptual representation of emotion plays a central role in how people understand the emotions both they and other people feel. Although decades of research indicate that adults typically represent emotion concepts as multidimensional, with valence (positive-negative) and arousal (activating-deactivating) as two primary dimensions, little is known about how this bidimensional (or ) representation arises. Here we show that emotion representations develop from a monodimensional focus on valence to a bidimensional focus on both valence and arousal from age 6 to age 25. We investigated potential mechanisms underlying this effect and found that increasing verbal knowledge mediated emotion representation development over and above three other potential mediators: (i) fluid reasoning, (ii) the general ability to represent non-emotional stimuli bidimensionally, and (iii) task-related behaviors (e.g., using extreme ends of rating scales). These results suggest that verbal development facilitates the expansion of emotion concept representations (and potentially emotional experiences) from a "positive or negative" dichotomy in childhood to a multidimensional organization in adulthood.

Effective emotion regulation is critical for mental health and well-being, rendering insight into underlying mechanisms that facilitate this crucial skill invaluable. We combined principles of cognitive linguistics and basic affective science to test whether shifting components of one's language might foster effective emotion regulation. In particular, we explored bidirectional relations between emotion regulation and linguistic signatures of psychological distancing. In Study 1, we assessed whether people spontaneously distance their language (i.e., shift their word use to be less socially and temporally proximate) when regulating emotions. Participants transcribed their thoughts while either passively viewing or actively regulating their emotional responses to negative images. Regulation increased linguistic markers of social and temporal distance, and participants who showed greater linguistic distancing were more successful regulators. Study 2 reversed this relation and investigated whether distancing one's language spontaneously regulated one's emotions. Participants wrote about negative images either using psychologically "close" or "distant" language in physical, social, and temporal domains. All 3 domains of linguistic distancing spontaneously reduced negative affect. Distancing language also "bled" across domains (e.g., temporal distancing spontaneously produced social distancing). This suggests that distancing one's language in 1 domain (e.g., reducing use of present-tense verbs) produces shifts in deep representations of psychological distance that are measurable across domains (e.g., reduced use of the word "I"). Results extend understanding of language-emotion interactions and reveal novel strategies for reducing negative affect. (PsycINFO Database Record

The demands of social life often require categorically judging whether someone's continuously varying facial movements express "calm" or "fear," or whether one's fluctuating internal states mean one feels "good" or "bad." In two studies, we asked whether this kind of categorical, "black and white," thinking can shape the perception and neural representation of emotion. Using psychometric and neuroimaging methods, we found that (a) across participants, judging emotions using a categorical, "black and white" scale relative to judging emotions using a continuous, "shades of gray," scale shifted subjective emotion perception thresholds; (b) these shifts corresponded with activity in brain regions previously associated with affective responding (i.e., the amygdala and ventral anterior insula); and (c) connectivity of these regions with the medial prefrontal cortex correlated with the magnitude of categorization-related shifts. These findings suggest that categorical thinking about emotions may actively shape the perception and neural representation of the emotions in question.

Generosity is contagious: People imitate others' prosocial behaviors. However, research on such prosocial conformity focuses on cases in which people merely reproduce others' positive actions. Hence, we know little about the breadth of prosocial conformity. Can prosocial conformity cross behavior types or even jump from behavior to affect? Five studies address these questions. In Studies 1 to 3, participants decided how much to donate to charities before learning that others donated generously or stingily. Participants who observed generous donations donated more than those who observed stingy donations (Studies 1 and 2). Crucially, this generalized across behaviors: Participants who observed generous donations later wrote more supportive notes to another participant (Study 3). In Studies 4 and 5, participants observed empathic or non-empathic group responses to vignettes. Group empathy ratings not only shifted participants' own empathic feelings (Study 4), but they also influenced participants' donations to a homeless shelter (Study 5). These findings reveal the remarkable breadth of prosocial conformity.

OBJECTIVE: The purpose of this study was to describe chiropractic care use at the World Games 2013. METHODS: In this retrospective study, we reviewed treatment charts of athletes and non-athletes who sought chiropractic care at The World Games in Cali, Colombia, from July 25 to August 4, 2013. Doctors of chiropractic of the International Federation of Sports Chiropractic provided care. Chart notes included body region treated, treatment modality, and pretreatment and posttreatment pain ratings. RESULTS: Of the participants, 537 of 2964 accredited athletes and 403 of 4131 accredited non-athletes sought chiropractic treatment; these represent utilization rates of 18.1% for athletes and 9.8% for non-athletes. A total of 1463 treatments were recorded for athletes (n = 897) and non-athletes (n = 566). The athletes who were treated represented 28 of 33 sports and 68 of 93 countries that were present at the games. Among athletes, the thoracic spine was the most frequent area of treatment (57.2%), followed by the lumbar spine (48.7%) and the cervical spine (38.9%). Myotherapy was the most frequently used treatment method (80.9%), followed by chiropractic manipulation (78.5%), taping (38.0%), and mobilization (24.6%). Reports of acute injury were higher among athletes (45.4%) compared with non-athletes (23.8%). Reported pain was reduced after treatment (P < .001), and 86.9% patients reported immediate improvement after receiving chiropractic treatment. CONCLUSIONS: The majority of people seeking chiropractic care at an international sporting competition were athletes. For those seeking care, the injury rate was higher among athletes than among non-athletes. The majority of patients receiving chiropractic care reported improvement after receiving care.
Nook, E. C., Lindquist, K. A., & Zaki, J. (2015). A new look at emotion perception: Concepts speed and shape facial emotion recognition. Emotion , 15 (5), 569-78. Publisher's VersionAbstract
Decades ago, the "New Look" movement challenged how scientists thought about vision by suggesting that conceptual processes shape visual perceptions. Currently, affective scientists are likewise debating the role of concepts in emotion perception. Here, we utilized a repetition-priming paradigm in conjunction with signal detection and individual difference analyses to examine how providing emotion labels-which correspond to discrete emotion concepts-affects emotion recognition. In Study 1, pairing emotional faces with emotion labels (e.g., "sad") increased individuals' speed and sensitivity in recognizing emotions. Additionally, individuals with alexithymia-who have difficulty labeling their own emotions-struggled to recognize emotions based on visual cues alone, but not when emotion labels were provided. Study 2 replicated these findings and further demonstrated that emotion concepts can shape perceptions of facial expressions. Together, these results suggest that emotion perception involves conceptual processing. We discuss the implications of these findings for affective, social, and clinical psychology.
