People’s behavior is characterized by stable if…then… profiles, or if in x situation then behavior a, but if in y situation then behavior b. But how do researchers conceptualize and measure if…then… profiles? Drawing from Cognitive-Affective Processing System (CAPS) theory, we discuss recent developments in assessing if…then… profiles, and how such profiles can provide a window for elucidating key aspects of the underlying personality system. Specifically, the Highly-Repeated Within-Person (HRWP) approach assesses how a behavior varies as a function of key features in a situation, and operationalizes if…then… profiles as regression betas. We illustrate how the HRWP approach can be applied to data from often-used social cognitive tasks, wherein an individual is exposed to a large number of situations that differ on a dimension that has been experimentally-manipulated by the researcher, and their behaviors to the situations are tracked. The HRWP approach allows researchers to more precisely assess a given individual’s if…then… pattern, make stronger causal inferences about a given individual’s personality system, and empirically investigate, rather than simply assume, if there are meaningful differences between individuals in the causal processes.

The implications of conceptualizing personality as a cognitive-affective processing system that functions as a parallel constraint satisfaction network are explored. Computer simulations show that from dynamic interactions among the units in such a network, a set of stable attractor states and functionally equivalent groups of situations emerge, such that IF exposed to situation group X, THEN the system settles in attractor Y. This conceptualization explicitly models the effect of situations on a given individual, and therefore can also be used to model the function of interpersonal systems. We demonstrate this possibility by modeling dyadic systems in which one partner's behavior becomes the situational input into the other partner's personality system, and vice versa. The results indicate that each member of the dyad will, in general, exhibit new attractor states. This suggests that the thoughts, affects, and behaviors that an individual typically experiences are a function not of that individual's personality system alone, but rather a function of the interpersonal system of which the individual is a part. Just as individuals have distinctive and stable IF-THEN signatures, so do interpersonal relationships. Understanding the structure of the cognitive-affective processing system of each relationship partner also should enable predictions of their distincitve relational signatures as emergent properties of the interpersonal system that develops.

In recent developments, the ASU HB5 has been modified so that the timing, positioning, and scanning of the finely focused electron probe can be entirely controlled by a host computer. This made the asynchronized handshake possible between the HB5 STEM and the image processing system which consists of host computer (PDP 11/34), DeAnza image processor (IP 5000) which is interfaced with a low-light level TV camera, array processor (AP 400) and various peripheral devices. This greatly facilitates the pattern recognition technique initiated by Monosmith and Cowley. Software called NANHB5 is under development which, instead of employing a set of photo-diodes to detect strong spots on a TV screen, uses various software techniques including on-line fast Fourier transform (FFT) to recognize patterns of greater complexity, taking advantage of the sophistication of our image processing system and the flexibility of computer software.

Cardiac tissue engineering aims at creating contractile structures that can optimally reproduce the features of human cardiac tissue. These constructs are becoming valuable tools to model some of the cardiac functions, to set preclinical platforms for drug testing, or to alternatively be used as therapies for cardiac repair approaches. Most of the recent developments in cardiac tissue engineering have been made possible by important advances regarding the efficient generation of cardiac cells from pluripotent stem cells and the use of novel biomaterials and microfabrication methods. Different combinations of cells, biomaterials, scaffolds, and geometries are however possible, which results in different types of structures with gradual complexities and abilities to mimic the native cardiac tissue. Here, we intend to cover key aspects of tissue engineering applied to cardiology and the consequent development of cardiac organoids. This review presents various facets of the construction of human cardiac 3D constructs, from the choice of the components to their patterning, the final geometry of generated tissues, and the subsequent readouts and applications to model and treat cardiac diseases.

Penile cancer is an uncommon malignancy that occurs most frequently in developing countries. Two pathways for penile carcinogenesis are currently recognized: one driven by human papillomavirus (HPV) infection and another HPV-independent route, associated with chronic inflammation. Progress on the clinical management of this disease has been slow, partly due to the lack of preclinical models for translational research. However, exciting recent developments are changing this landscape, with new in vitro and in vivo models becoming available. These include mouse models for HPV+ and HPV− penile cancer and multiple cell lines representing HPV− lesions. The present review addresses these new advances, summarizing available models, comparing their characteristics and potential uses and discussing areas that require further improvement. Recent breakthroughs achieved using these models are also discussed, particularly those developments pertaining to HPV-driven cancer. Two key aspects that still require improvement are the establishment of cell lines that can represent HPV+ penile carcinomas and the development of mouse models to study metastatic disease. Overall, the growing array of in vitro and in vivo models for penile cancer provides new and useful tools for researchers in the field and is expected to accelerate pre-clinical research on this disease.

Emotion Concepts

Social functioning requires emotion. We must be able to recognize, interpret, and generate emotions across a variety of social contexts. But how are emotions conceptually represented in the mind? Embodiment (or grounded cognition) theories propose that processing of emotional concepts is partly based in one’s own perceptual, motor, and somatosensory systems. We review evidence for this account across a variety of domains, including facial expression perception, interpretation of emotional language, somatic involvement in affective processing, and “mirroring” of others’ actions. We also contrast embodiment theories with more traditional “amodal” frameworks, which represent emotional information as abstract language-like symbols in cognitive networks. Overall, we argue that a comprehensive account of emotion concepts requires considering their embodiment. Simultaneously, we highlight that embodiment is flexible and dynamic, especially within the social environment. This means that when and how emotion concepts are embodied critically depends on situational cues and current representational needs.

The FMR1 gene in its premutation (PM) state has been linked to a range of clinical and subclinical phenotypes among FMR1 PM carriers, including some subclinical traits associated with autism spectrum disorder (ASD). This study attempted to further characterize the phenotypic profile associated with the FMR1 PM by studying a battery of assessments examining clinical-behavioral traits, social-cognitive, and executive abilities in women carrying the FMR1 PM, and associations with FMR1-related variability. Participants included 152 female FMR1 PM carriers and 75 female controls who were similar in age and IQ, and screened for neuromotor impairments or signs of fragile X-associated tremor/ataxia syndrome. The phenotypic battery included assessments of ASD-related personality and language (i.e., pragmatic) traits, symptoms of anxiety and depression, four different social-cognitive tasks that tapped the ability to read internal states and emotions based on different cues (e.g., facial expressions, biological motion, and complex social scenes), and a measure of executive function. Results revealed a complex phenotypic profile among the PM carrier group, where subtle differences were observed in pragmatic language, executive function, and social-cognitive tasks that involved evaluating basic emotions and trustworthiness. The PM carrier group also showed elevated rates of ASD-related personality traits. In contrast, PM carriers performed similarly to controls on social-cognitive tasks that involved reliance on faces and biological motion. The PM group did not differ from controls on self-reported depression or anxiety symptoms. Using latent profile analysis, we observed three distinct subgroups of PM carriers who varied considerably in their performance across tasks. Among PM carriers, CGG repeat length was a significant predictor of pragmatic language violations. Results suggest a nuanced phenotypic profile characterized by subtle differences in select clinical-behavioral, social-cognitive, and executive abilities associated with the FMR1 PM in women.

Emotions are traditionally viewed as detrimental to judicial responsibility, a belief rooted in the classical view of the mind as a battle ground between reason and emotion. Drawing on recent developments in psychology and neuroscience we propose that the brain uses past experience, organized as concepts, to guide actions and give sensations meaning, constructing experiences such as “fear” or “anger”. Wisdom comes from skill at constructing emotions in a more precise and functional way, a skill called “emotional granularity”. Studies show that individuals who are more emotionally granular have better function across a range of domains, including self regulation and decision making. We propose that effective judicial decision-making does not require a dispassionate judge, but a judge who is high in emotional granularity. We lay out an empirical agenda for testing this idea and end by discussing empirically supported recommendations for increasing emotional granularity in the judiciary. Tradicionalmente, se ha considerado que las emociones son perjudiciales para el desempeño responsable de la labor judicial, una creencia enraizada en la concepción clásica de la mente como campo de batalla entre razón y emoción. Partiendo de nuevos descubrimientos en psicología y neurociencia, argumentamos que el cerebro usa la experiencia pasada, organizada como conceptos, para guiar las acciones y dar sentido a las sensaciones, construyendo experiencias como “miedo” o “ira”. La sabiduría proviene de la habilidad en construir emociones de un modo más preciso y funcional, habilidad denominada “granularidad emocional”. Los estudios muestran que los individuos más granulares emocionalmente funcionan mejor en varios dominios, incluyendo la autorregulación y la toma de decisiones. Argumentamos que la toma de decisiones eficaz en judicatura no requiere de un juez desapasionado, sino de un juez que tenga alta granularidad emocional. Proponemos un programa empírico para poner a prueba esa idea, y concluimos con un debate de recomendaciones de base empírica para aumentar la granularidad emocional en la judicatura.

In this study, we tracked the development of rhythmic entrainment, prosociality, and theory of mind skills in children attending music and sports programs and in a control group over the course of three years. Forty-five children (mean age at onset = 81 months) drummed in two contextual conditions – alone and social – completed the Reading the Mind in the Eyes test and prosocial tasks (helping and sharing). All children improved in their ability to entrain to external rhythms over time, with the music group outperforming controls in the entrainment-social condition. Developmental effects were found for theory of mind, but no significant group differences. Although there were no significant group differences for prosociality, following three years of music education, entrainment scores in the alone condition were positively correlated with the number of stickers that children in the music group gave to friends. Results are discussed in light of the nature of collective music learning through ensemble participation and its role in the development of social-cognitive and prosocial skills in childhood.

Causal Processes

Process tracing is an in-depth case study method that can be used to study how causal processes play out within cases. Given its focus on processes and temporality, process tracing is a useful method for analyzing crisis and crisis decision making in the fields of foreign policy analysis and public policy. As can be seen from its name, process tracing involves theorizing a causal process that is then traced by investigating the observable manifestations of the operation of the process as a whole in the more minimalist variant, or for each of its parts in the more maximalist variant. Minimalist process tracing is typically used early in a research program as a form of plausibility probe to understand what types of processes might be linking a crisis event with particular outcomes like policy change. Maximalist process tracing can then be used once there is preliminary knowledge about processes, and where the goals become gaining a better theoretical understanding of how they operate, and making stronger causal inferences using more direct evidence of their operation.
