Do Programmers Prefer Predictable Expressions in Code?

Source code is a form of human communication, albeit one where the information shared between the programmers reading and writing the code is constrained by the requirement that the code executes correctly. Programming languages are more syntactically constrained than natural languages, but they are also very expressive, allowing a great many different ways to express even very simple computations. Still, code written by developers is highly predictable, and many programming tools have taken advantage of this phenomenon, relying on language model surprisal as a guiding mechanism. While surprisal has been validated as a measure of cognitive load in natural language, its relation to human cognitive processes in code is still poorly understood. In this paper, we explore the relationship between surprisal and programmer preference at a small granularity—do programmers prefer more predictable expressions in code? Using meaning-preserving transformations, we produce equivalent alternatives to developer-written code expressions and run a corpus study on Java and Python projects. In general, language models rate the code expressions developers choose to write as more predictable than these transformed alternatives. Then, we perform two human subject studies asking participants to choose between two equivalent snippets of Java code with different surprisal scores (one original and transformed). We find that programmers do prefer more predictable variants, and that stronger language models like the transformer align more often and more consistently with these preferences.     

Working with Bangladeshi young women

The author describes once-weekly psychoanalytically informed work in a child mental health setting with young Bangladeshi women making the transition to adulthood. She argues that the prevalent notion of 'culture conflict' used to account for patterns of emotional disturbance and self-harm in these young women is reductionist and represents a denial of severe family dysfunction and individual psychic pain. She shows how, despite cultural differences, psychoanalytically informed thinking can provide a basis for understanding these young women's experience and facilitate their emotional growth. However, faced with complex unconscious processes, the worker has to remain alert to her countertransference in order not to be drawn into an unhelpful collusion or denial of reality. Organizational defences may also operate to protect staff and their institutions from awareness of such high levels of emotional distress, which therefore remain hidden. The author is grateful to the two young women who consented to publication in the hope that it might help others. Details have been changed to protect their anonymity.     

How do children view and categorise human and dog facial expressions?

Children are often surrounded by other humans and companion animals (e.g., dogs, cats); and understanding facial expressions in all these social partners may be critical to successful social interactions. In an eye-tracking study, we examined how children (4–10 years old) view and label facial expressions in adult humans and dogs. We found that children looked more at dogs than humans, and more at negative than positive or neutral human expressions. Their viewing patterns (Proportion of Viewing Time, PVT) at individual facial regions were also modified by the viewed species and emotion, with the eyes not always being most viewed: this related to positive anticipation when viewing humans, whilst when viewing dogs, the mouth was viewed more or equally compared to the eyes for all emotions. We further found that children's labelling (Emotion Categorisation Accuracy, ECA) was better for the perceived valence than for emotion category, with positive human expressions easier than both positive and negative dog expressions. They performed poorly when asked to freely label facial expressions, but performed better for human than dog expressions. Finally, we found some effects of age, sex, and other factors (e.g., experience with dogs) on both PVT and ECA. Our study shows that children have a different gaze pattern and identification accuracy compared to adults, for viewing faces of human adults and dogs. We suggest that for recognising human (own-face-type) expressions, familiarity obtained through casual social interactions may be sufficient; but for recognising dog (other-face-type) expressions, explicit training may be required to develop competence.

Highlights

• We conducted an eye-tracking experiment to investigate how children view and categorise facial expressions in adult humans and dogs
• Children's viewing patterns were significantly dependent upon the facial region, species, and emotion viewed
• Children's categorisation also varied with the species and emotion viewed, with better performance for valence than emotion categories
• Own-face-types (adult humans) are easier than other-face-types (dogs) for children, and casual familiarity (e.g., through family dogs) to the latter is not enough to achieve perceptual competence

     

Physical activity and body image: Intertwined health priorities identified by transmasculine young people in a non-metropolitan area

Abstract

Background: A dearth of research exists about the health behaviors of transgender young people (TYP). As we seek to learn more about transgender (trans) health, community-based participatory research (CBPR) approaches are crucial for incorporating TYP’s needs into the formulation of research questions and development of health behavior programing.

Aim: Explore body image and exercise as priorities among TYP.

Methods: Trans masculine young adults (N?=?16) in a small city in the Midwest took part in semi-structured interviews about their health behaviors and priorities. Theme analysis was used to capture key patterns in participants’ responses. Specific analysis steps included initial and more specific coding, analytical memos, organizational matrices and reports, and discussion about results with participants.

Results: Participants identified exercise and body image as connected primary health concerns. They discussed these issues in terms of three themes: Body shape as motivation for exercise; Poor body image, stigma and fear as exercise barriers, and; Exercise or lack of, as destructive. Participants wanted to exercise to achieve a certain body shape, not for health or as stress relief. They cited gyms as unwelcoming, however. They also worried about discrimination and did not feel sufficiently comfortable with their bodies to exercise. When they could not exercise, they used harmful behaviors, like restricted eating, to achieve a specific male shape.

Conclusions: Using participatory methods allowed us to understand the priorities of a group of Transmasculine young people. Our findings suggest that it is important to continue to explore TYP’s body-related motivations for exercise and understand the balance between exercise as a positive health behavior, and a potentially harmful one, in light of TYP’s complex body image concerns. Trans friendly gyms and gym policies could promote safe exercise and continued anti trans discrimination work and policy advocacy can promote the safety of TYP in all spaces.     

Affective development and etiological implication in body image disorders and anorexia: reflections on bdd manifestations and refusal of food in a psychodynamic view

The literature demonstrates that relational experiences during childhood have a strong impact on the trajectories of psychological growth. This article focuses on the major developmental phases for identity formation, psychological growth, mentalization skills, and ability to share affective states. It presents a careful analysis of some key factors that influence the representation of body image and the relationship with food, from a perspective that integrates relational psychodynamic models. In particular, it looks at the ways in which individuals and caregivers actively co-create the symptomatic process of intrapsychic reality in which body disease and refusal of food are performed.     

松果体再认识的哲学思考

长期以来，对大脑松果体一直了解不多。认为它的作用微不足道。只是由于科学技术的发展，对它的研究不断深入，才认识到它是人类很重要的内分泌腺体。它与衰老、免疫、抗病、长寿等都有密切关系，是人类内分泌的主宰和调控。这说明一切事物总是由不知到知之。客观存在的事物都可以认识。     

Triangulating causality between childhood obesity and neurobehavior: Behavioral genetic and longitudinal evidence

Childhood obesity is a serious health concern that is not yet fully understood. Previous research has linked obesity with neurobehavioral factors such as behavior, cognition, and brain morphology. The causal directions of these relationships remain mostly untested. We filled this gap by using the Adolescent Brain Cognitive Development study cohort comprising 11,875 children aged 9–10. First, correlations between the age- and sex-specific 95th BMI percentile (%BMIp95) and neurobehavioral measures were cross-sectionally analyzed. Effects were then aggregated by neurobehavioral domain for causal analyses. Behavioral genetic Direction of Causation modeling was used to test the direction of each relationship. Findings were validated by longitudinal cross-lagged panel modeling. %BMIp95 correlated with impulsivity, motivation, psychopathology, eating behavior, and cognitive tests (executive functioning, language, memory, perception, working memory). Greater %BMIp95 was also associated with reduced cortical thickness in frontal and temporal brain areas but with increased thickness in parietal and occipital areas. Similar although weaker patterns emerged for cortical surface area and volume. Behavioral genetic modeling suggested causal effects of %BMIp95 on eating behavior (β = 0.26), cognition (β = 0.05), cortical thickness (β = 0.15), and cortical surface area (β = 0.07). Personality/psychopathology (β = 0.09) and eating behavior (β = 0.16) appeared to influence %BMIp95. Longitudinal evidence broadly supported these findings. Results regarding cortical volume were inconsistent. Results supported causal effects of obesity on brain functioning and morphology. The present study highlights the importance of physical health for brain development and may inform interventions aimed at preventing or reducing pediatric obesity.

Research Highlights

• A continuous measure related to obesity, %BMIp95, has correlations with various measures of brain functioning and structure
• Behavioral genetic and longitudinal modeling suggest causal links from personality, psychopathology, and eating behavior to %BMIp95
• Results also indicate directional links from %BMIp95 to eating behavior, cognition, cortical thickness, and cortical surface area
• Obesity may play a role for healthy brain development during childhood
