RESUMEN

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.

RESUMEN

This study evaluated the aspects of complex decisions influenced by peers, and components of peer involvement influential to adolescents' risky decisions. Participants (N = 140) aged 13-25 completed the Columbia Card Task (CCT), a risky choice task, isolating deliberation-reliant and affect-reliant decisions while alone, while a friend monitors choices, and while a friend is merely present. There is no condition in which a nonfriend peer is present. Results demonstrated the risk-increasing peer effect occurred in the youngest participants in the cold CCT and middle-late adolescents in the hot CCT, whereas other ages and contexts showed a risk-decreasing peer effect. Mere presence was not sufficient to influence risky behavior. These boundaries in age, decision, and peer involvement constrain prevailing models of adolescent peer influence.

RESUMEN

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.

RESUMEN

This study investigates (a) age-related differences in how the intensity of stereotyped facial expressions influence the emotion label children, adolescents, and adults assign to that face and (b) how this perceptual sensitivity relates to subclinical symptoms of psychopathology. In 2015-2016, 184 participants aged 4-25 years viewed posed stereotypes of angry, fearful, sad, and happy expressions morphed with neutral expressions at 10%-90% intensity. Thin plate regression smoothing splines were used to chart nonlinear associations between age and the perceptual threshold participants needed to assign the emotion label expected based on cultural consensus. Results suggest that sensitivity to labeling stereotypical happy faces as "happy" peaked by age 4. Sensitivity to perceiving stereotypical angry faces as "angry" increased from ages 4 to 7 and then plateaued. In contrast, sensitivity to perceiving stereotypical fearful and sad faces demonstrated protracted development, not reaching a plateau until ages 15 and 16, respectively. Reduction in selecting the "I don't know" response was the primary driver of these age-related changes. Stereotyped fear expressions required the highest intensity to be labeled as such and showed the most marked change in perceptual threshold across development. Interestingly, lower intensity morphs of stereotypical fear faces were frequently labeled "sad." Furthermore, perceiving lower intensity fear morphs was associated with fewer internalizing and externalizing symptoms in participants aged 7-19. This study describes the development of perceptual sensitivity to labeling stereotypical expressions of emotion according to cultural consensus and shows that how people perceive and categorize ambiguous facial expressions is associated with vulnerability to psychopathology.

RESUMEN

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.

RESUMEN

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 (N = 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 concrete 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 abstract 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.

RESUMEN

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 (p-factor) 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.

RESUMEN

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.1-6 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,7-10 little is known about how this bidimensional (or circumplex) representation arises.11 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.

RESUMEN

Although models of exploratory decision making implicate a suite of strategies that guide the pursuit of information, the developmental emergence of these strategies remains poorly understood. This study takes an interdisciplinary perspective, merging computational decision making and developmental approaches to characterize age-related shifts in exploratory strategy from adolescence to young adulthood. Participants were 149 12-28-year-olds who completed a computational explore-exploit paradigm that manipulated reward value, information value, and decision horizon (i.e., the utility that information holds for future choices). Strategic directed exploration, defined as information seeking selective for long time horizons, emerged during adolescence and maintained its level through early adulthood. This age difference was partially driven by adolescents valuing immediate reward over new information. Strategic random exploration, defined as stochastic choice behavior selective for long time horizons, was invoked at comparable levels over the age range, and predicted individual differences in attitudes toward risk taking in daily life within the adolescent portion of the sample. Collectively, these findings reveal an expansion of the diversity of strategic exploration over development, implicate distinct mechanisms for directed and random exploratory strategies, and suggest novel mechanisms for adolescent-typical shifts in decision making.
