Do infants perceive the social robot Keepon as a communicative partner?

This study investigates if infants perceive an unfamiliar agent, such as the robot Keepon, as a social agent after observing an interaction between the robot and a human adult. 23 infants, aged 9–17 month, were exposed, in a first phase, to either a contingent interaction between the active robot and an active human adult, or to an interaction between an active human adult and the non-active robot, followed by a second phase, in which infants were offered the opportunity to initiate a turn-taking interaction with Keepon.The measured variables were: (1) the number of social initiations the infant directed toward the robot, and (2) the number of anticipatory orientations of attention to the agent that follows in the conversation. The results indicate a significant higher level of initiations in the interactive robot condition compared to the non-active robot condition, while the difference between the frequencies of anticipations of turn-taking behaviors was not significant.     

“Paid to Endure”: Paid Research Participation,Passivity, and the Goods of Work

A growing literature documents the existence of individuals who make a living by participating in phase I clinical trials for money. Several scholars have noted that the concerns about risks, consent, and exploitation raised by this phenomenon apply to many (other) jobs, too, and therefore proposed improving subject protections by regulating phase I trial participation as work. This article contributes to the debate over this proposal by exploring a largely neglected worry. Unlike most (other) workers, subjects are not paid to produce or achieve anything but to have things done to them. I argue that this passivity is problematic for reasons of distributive justice. Specifically, it fails to enable subjects to realize what Gheaus and Herzog call “the goods of work”—a failure not offset by adequate opportunities to realize these goods outside of the research context. I also consider whether granting subjects worker-type protections would accommodate this concern.

Envisioning human service organizations free of microaggressions

Microaggressions refer to verbal or non-verbal communications that invalidate those with non-dominant group identities across all dimensions of human diversity. Within human service organizations (HSOs), microaggressions may lower therapeutic alliance, reduce retention, and result in negative outcomes. While understanding the type, frequency, and damaging impact of microaggressions are useful and well established in research, less is known about the organizational policies, practices, behaviors, and values needed to reduce or eradicate microaggressions within human service contexts. Utilizing three focus groups and four individual interviews with adults who received services from HSOs, this qualitative study explored: What would HSOs need to learn, practice, and believe in order to be free of microaggressions? Sixteen participants reported on the provider's knowledge and behaviors, organizational environment, and institutional characteristics needed to create an organization free of microaggressions. Limitations of existing approaches and implications to develop more equitable practices within HSOs are discussed.     

The role of television in language acquisition

The conventional view among developmental psychologists is that television viewing does not contribute to a young viewer's language acquisition. That assumption is challenged. Evidence is presented that suggests that children can learn about language as they view television: (1) From age 2, children attend to television and view in an active, purposeful manner. (2) Some programs present dialogue in an attention-getting, content-redundant context. (3) Children can learn word meanings when viewing. (4) Children draw upon television as a source of verbal routines for their own play interactions.     

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.     

Motor learning of cue-dependent pull-force changes during an isometric precision grip task

The “raspberry task” represents a precision grip task that requires continuous adjustment of grip and pull forces. During this task subjects grip a specialized grip rod and have to increase the pull force linearly while the rod is locked. The aim of this study was to determine whether an associated, initially neutral cue is able to evoke pull-force changes in the raspberry task. A standard delay paradigm was used to study cued pull-force changes during an ongoing movement resulting in unloading. Pull force and EMG activity of hand and arm muscles were recorded from 13 healthy, young subjects. The cue was associated with a complex change in motor behavior.In this task, cued force changes take place more rapidly than in protective reflex systems (in median after the second presentation of the cueing stimulus). A cued force change was detectable in two-thirds of paired trials. Although the force change is produced by a decrease of the EMG activity in several grip- and pull-force-producing muscles, the most significant effect in the majority of the subjects was an increase of the activity of the flexor carpi ulnaris muscle which antagonises corresponding pull-force-producing muscles. Cued force changes require adequately and precisely controlled activation of the muscle groups involved in the movement.     

The development of sex typing: Themes from recent research

A conceptual framework for organizing the constructs and content areas included in research on sex typing is presented in this review of recent research on the development of sex typing. Two major themes are discussed. First, sex-typed play activities and interests emerge clearly in the first few years of life. Both play activities and peer preferences are sex typed earlier and more definitely than are personality traits and social behaviors such as aggression or dependency. It is suggested that researchers have underemphasized the importance of interests, activities, and peer associations while overemphasizing personality attributes as the core of sex typing. The second theme is that cognitions and concepts about sex typing are important in the acquisition of gender typing, but they are not sufficient by themselves for understanding the process by which sex-typed behavior is acquired. Children's sex-role concepts are sometimes related to their behavioral preferences, but other factors are also important influences on behavior.     

Ego development in perspective: Structural stage,functional phase,and cultural age-period models

Ego development is emerging as one of the more important areas of research in developmental psychology. This paper presents a structural stage approach to ego development and distinguishes it from two other models of ego development, which are termed functional phases and cultural ages. Two subtypes are also delineated within the structural stage approach—a monodomain and a multisubdomain—and the latter is argued for. These concepts are then illustrated through an analysis of four prominent ego development theories—those of Robert Selman, Robert Kegan, Jane Loevinger, and Erik Erikson. The important similarities and critical differences of the theories are clarified, which enables the authors to present a summary integration.
