Touching my face with my supernumerary hand: a cheeky illusion

A self-touch paradigm elicits a surprising illusion. With the participant's eyes closed, the examiner guides the participant's right index finger to administer strokes and taps to the right side of the participant's face. At the same time, the examiner strokes and taps the corresponding location on the left side of the participant's face. Although the participant administered touch to only the right side of the face, this paradigm elicited the illusion of self-touch to both sides of the face, and the illusion often implicated a third, disconnected or disembodied, hand. We propose an explanation, and draw parallels with the phenomenon of supernumerary phantom limb.     

Low-income mothers' patterns of partnership instability and adolescents' socioemotional well-being

The present study investigated the association of family structure and maternal partnership instability patterns with adolescents' behavioral and emotional well-being among urban low-income families. Analyses employed data from the Three-City Study to track maternal partnerships over the youth's life span, linking longitudinal family structure and transition patterns to adolescent well-being (N = 2305). Families were classified into nine mutually exclusive longitudinal partnership groups based on current status at wave 3 (single, married, or cohabiting) and the longevity of that status: always (since adolescent's birth with no transitions), stable (lasting two years or more, preceded by transitions), or new (transpiring in the past 2 years). Adolescents in the always married group displayed less delinquency and externalizing problems, according to both youth and mother reports, than peers in always single-parent or newly married households. In contrast, youth in always cohabiting households had higher maternal ratings of internalizing problems and youth with newly cohabiting mothers reported higher psychological distress than peers in similar stability groups with single or married mothers. Overall, several potential explanatory processes for the family structure and stability patterns surfaced: married parent families reported less economic hardship, more family routines and father involvement, and less maternal psychological distress and parenting stress than their single and cohabiting counterparts. Policy implications of these findings are discussed.     

Correspondence in parents' and children's concepts of god: Investigating the role of parental values,religious practices and executive functioning

This study examined the extent to which children's concepts of God correspond with their parents' concepts of God. It also examined how parent-context factors and children's executive functioning relate to parent–child conceptual similarity. Parent–child dyads from varied religious and racial backgrounds participated. Dyads had the greatest conceptual similarity concerning God's mind-dependent functions. Though correspondence between parents and children was lowest concerning God's body-dependent functions, dyads were more similar about those functions when parents engaged in more frequent religious practices with their child and thought God was important. Children's concepts of God were unrelated to religious practices, and parent–child conceptual similarity was unrelated to children's age and executive functioning. Simply put, variation among parents' anthropomorphic concepts of God drove variation in parent–child conceptual similarity. Overall, these findings suggest that embodied concepts of God may be most sensitive to cultural input and that socialization practices provide greater insight into parents' anthropomorphic concepts.     

Learning From Fantasy and Real Characters in Preschool and Kindergarten

In three experiments, 3½- to 6-year-old children were presented with analogical problems in which the protagonists were either real people or fantasy characters. Children were more likely to transfer solutions from the stories about real people rather than the stories about fantasy characters. These results suggest that the use of a fantasy character might not be an effective strategy for teaching children information that is meant to be applied to the real world.     

Adult age differences in interference from a prospective-memory task: a diffusion model analysis

People often slow down their ongoing activities when they must remember an intended action, known as the cost or interference effect of prospective memory (PM). Only a few studies have examined adult age differences in PM interference, and the specific reasons underlying such differences are not well understood. The authors used a model-based approach to reveal processes underlying PM interference and age differences in these processes. Older and younger adults first performed a block of an ongoing lexical decision task alone. An embedded event-based PM task was added in a second block. Simultaneously accounting for the changes in response time distributions and error rates induced by the PM task, Ratcliff’s (Psychological Review 85:59–108, 1978) diffusion model was used to decompose the nonlinear combination of speed and accuracy into psychologically meaningful components. Remembering an intention not only reduced processing efficiency in both age groups, but also prolonged peripheral nondecision times and induced response cautiousness. Overall, the findings suggest that there are multiple, but qualitatively similar factors underlying PM task interference in both age groups.     

On being happy and gullible: Mood effects on skepticism and the detection of deception

Are we more likely to believe or disbelieve another person depending on our mood state? Based on past research on interpersonal communication and recent work on affect and social cognition, we predicted and found that negative mood increased and positive mood decreased people’s skepticism and their ability to detect deception, consistent with the more externally focused, accommodative processing style promoted by negative affect. After a mood induction using positive, neutral or negative films, participants viewed deceptive or truthful interviews with individuals who denied committing a theft. Judgments of the targets’ guilt and their truthfulness were collected. As predicted, negative mood increased judges’ skepticism towards the targets, and improved their accuracy in detecting deceptive communications, while judges in a positive mood were more trusting and gullible. The relevance of these findings for everyday judgments of trust and the detection of deception are considered, and their implications for recent affect-cognition theories are discussed.     

Attention set for number: expectation and perceptual load in inattentional blindness

Inattentional blindness is the failure to detect unexpected events when attention is otherwise engaged. Previous research indicates that inattentional blindness increases as perceptual demands intensify. The authors present 6 cuing experiments that manipulated both the perceptual demands of a primary letter-naming task and the expectations of the individual. Inattentional blindness was greatest for individuals who held a numerical expectation that was consistent with the number of primary-task items presented. Expectation also affected detection differentially at various levels of perceptual load: Detection at moderate and high perceptual load was significantly affected by expectation, whereas detection at low perceptual load was not. The authors suggest that at moderate to high levels of perceptual load, individuals whose numerical expectations are fulfilled terminate processing when the primary task is complete, at the expense of the unexpected visual event. These experiments provide compelling evidence that expectations do affect detection of an unexpected stimulus, and they are the first to demonstrate that individuals set their attention for the number of items to be detected and are vulnerable to inattentional blindness whenever their primary-task numerical expectation is fulfilled.     

The Philosophical Personality

The authors adopt a critico‐sociological methodology to investigate the current state of the philosophical profession. According to them, the question concerning the status of philosophy (“What is philosophy?”) cannot be answered from within the precinct of philosophical reason alone, since philosophy—understood primarily as a profession—is marked by a constitutive type of self‐ignorance that prevents it from reflecting upon its own sociological conditions of actuality. This ignorance, which is both cause and effect of the organization and investment of philosophical desire, causes philosophers to lose themselves in an ideological myth (“the philosopher as idea(l)”) according to which philosophers are unaffected by the material conditions in which they exist. This myth prevents philosophers from noticing the extent to which their activity is influenced by extra‐philosophical determinants that shape, empirically, who becomes a professional philosopher (“the philosopher as imago”) and who doesn't. This article explores the relationship between philosophy's “idea(l)” and its “imago” as a way of shedding light on some of the mechanisms that make philosophy inhospitable for so many women, people of color, and economic minorities.     

Personal Autonomy,Social Identity,and Oppressive Social Contexts

Attempts to articulate the ways in which membership in socially subordinated social identities can impede one's autonomy have largely unfolded as part of the debate between different types of internalist theories in relation to the problem of internalized oppression. The different internalist positions, however, employ a damage model for understanding the role of social subordination in limiting autonomy. I argue that we need an externalist condition in order to capture the ways in which membership in a socially subordinated identity can constrain one's autonomy, even if one is undamaged in one's autonomy competencies and self‐reflexive attitudes. I argue that living among those practically empowered to harass, to engage in racial profiling, and to treat as expendable is incompatible with a freedom‐condition required for unconstrained global self‐determination.     

Prospective memory in an air traffic control simulation: external aids that signal when to act

At work and in our personal life we often need to remember to perform intended actions at some point in the future, referred to as Prospective Memory. Individuals sometimes forget to perform intentions in safety-critical work contexts. Holding intentions can also interfere with ongoing tasks. We applied theories and methods from the experimental literature to test the effectiveness of external aids in reducing prospective memory error and costs to ongoing tasks in an air traffic control simulation. Participants were trained to accept and hand-off aircraft and to detect aircraft conflicts. For the prospective memory task, participants were required to substitute alternative actions for routine actions when accepting target aircraft. Across two experiments, external display aids were provided that presented the details of target aircraft and associated intended actions. We predicted that aids would only be effective if they provided information that was diagnostic of target occurrence, and in this study, we examined the utility of aids that directly cued participants when to allocate attention to the prospective memory task. When aids were set to flash when the prospective memory target aircraft needed to be accepted, prospective memory error and costs to ongoing tasks of aircraft acceptance and conflict detection were reduced. In contrast, aids that did not alert participants specifically when the target aircraft were present provided no advantage compared to when no aids were used. These findings have practical implications for the potential relative utility of automated external aids for occupations where individuals monitor multi-item dynamic displays.
