Internationally adopted children’s cognitive and social-emotional development during the first post-adoption year: A longitudinal study

Research is consistent in showing that international adoption is an intervention leading to great recovery for adopted children, but there is a need of research on factors associated with recovery. The present study is aimed at: (a) assessing children’s cognitive skills and social-emotional dimensions on their arrival to their new family; (b) evaluating their development after one year; (c) identifying which factors influence development, taking into account children’s gender, age, health status on arrival, years of institutionalization, and the initial psychological delay. Participants were 53 internationally adopted children (30 boys and 23 girls), aged 5.68 years old on average at placement (range 2–14). Results showed that children’s development one year after adoption was extraordinary, both in cognitive skills and in social-emotional dimensions. The children more delayed on arrival showed the larger progress over time, and their recovery was greater in cognitive skills than in social-emotional dimensions.     

The onset time delaying effect: smokers vs non-smokers place the adverse consequences of smoking further in the future

Despite all the information about the risks, many people still smoke. Several studies investigated risk perceptions in smokers. The adequate perceptions of the risks from smoking is particularly important and this study investigated the risk perception of young smokers vs non-smokers by a new time-estimation task in which we required participants (smokers and non-smokers) to estimate the onset time of smoking-related conditions in an average young smoker. The findings supported our main hypothesis that smokers, compared to non-smokers, postponed the onset of both mild and severe smoking-related conditions. The results also revealed that the onset time estimates for mild conditions given by both smokers and non-smokers were associated with their self-perceptions of risk and level of fear of developing smoking-related conditions. The findings cast light on smokers’ distorted temporal perception of the health-damaging consequences of smoking. Implications for the adequacy of risk perception in smokers are discussed.     

The Doctor(s) in House: An Analysis of the Evolution of the Television Doctor-Hero

The medical drama and its central character, the doctor-hero have been a mainstay of popular television. House M.D. offers a new (and problematic) iteration of the doctor-hero. House eschews the generic conventions of the "television doctor" by being neither the idealized television doctor of the past, nor the more recent competent but often fallible physicians in entertainment texts. Instead, his character is a fragmented text which privileges the biomedical over the personal or emotional with the ultimate goal of scientifically uncovering and resolving instances of disease. This article examines the implicit and explicit messages in House M.D. and critically analyzes both the show and its lead character in relation to the traditional medical drama genre that highlights the "doctor-hero" as the central character. While at first House seems to completely violate narrative and generic norms, ultimately the program provides a new form that reinforces the presence of the doctor-hero, but highlights House's character as the central figure who is personally and interpersonally problematic but biomedically effective.     

The Relationship Between the Fear-Avoidance Model of Pain and Personality Traits in Fibromyalgia Patients

This study examined the relationship between several cognitive-affective factors of the fear-avoidance model of pain, the big five model of personality, and functional impairment in fibromyalgia (FM). Seventy-four FM patients completed the NEO Five-Factor Inventory, the Pain Catastrophizing Scale, the Pain Anxiety Symptoms Scale-20, the Pain Vigilance and Awareness Questionnaire, and the Impairment and Functioning Inventory. Results indicated that the cognitive-affective factors of pain are differentially associated with personality traits. Neuroticism and conscientiousness were significant predictors of pain catastrophizing, and neuroticism, openness, and agreeableness were significant predictors of pain anxiety. Personality traits did not contribute significantly to vigilance to pain. The effect of neuroticism upon pain anxiety was mediated by pain catastrophizing, and neuroticism showed a trend to moderate the relationship between impairment and pain anxiety. Results support the fear-avoidance model of pain. Implications of the findings for the understanding and management of FM are discussed.     

When everything new is well-forgotten old: Vygotsky/Luria insights in the development of executive functions

The concept of "extra-cortical organization of higher mental functions" proposed by Lev Vygotsky and expanded by Alexander Luria extends cultural-historical psychology regarding the interplay of natural and cultural factors in the development of the human mind. Using the example of self-regulation, the authors explore the evolution of this idea from its origins to recent findings on the neuropsychological trajectories of the development of executive functions. Empirical data derived from the Tools of the Mind project are used to discuss the idea of using classroom intervention to study the development of self-regulation in early childhood.     

The cost of a strategy

Abstract

Experiment 1 demonstrated a new kind of dual-task interference effect. The primary task was a speeded left-right discrimination of stimulus position (R1). The un speeded secondary task consisted of reporting verbally whether the stimuli were the same or different (R2). Stimulus exposure time was either 150 or 2000 msec. Two groups of subjects performed the primary task only, whereas two other groups performed both tasks and were instructed to emit R1 before R2. It was reasoned that the decision would be made to emit R1 before R2, and that this decision would produce a lengthening of R1. The results supported this prediction. Experiment 2 showed that the interference effect also occurred when the subjects were not explicitly instructed to emit R1 before R2, and was not due to either the mere presence of the second task or to response grouping. Experiments 3 and 4 compared two possible models for explaining the interference effect, i.e. the capacity-sharing model and the postponement model. As predicted by the postponement model, task difficulty did not interact, or interacted underadditively, with task overlap (Experiment 3), and the interference effect was not influenced by the amount of processing resources devoted to the primary task (Experiment 4). It was concluded that this new type of interference effect is best explained by the version of the postponement model that locates the bottleneck at the decision stage.     

Domestic chicks perceive stereokinetic illusions

Stereokinetic illusions occur when certain 2-D patterns are set in slow rotation in a plane perpendicular to the line of sight. Such phenomena have never been investigated in animal species other than our own. We used the domestic chick (Gallus gallus) to check whether these illusions are experienced by non-human species, taking advantage of filial imprinting. Newly hatched visually naive chicks were individually exposed for 4 h to 2-D stimuli producing, to a human observer, the perception of a stereokinetic cone (experiment 1) or of a stereokinetic cylinder (experiment 2). Thereafter, each chick underwent a free-choice test between a solid 3-D cone and a solid 3-D cylinder. A control group of newly hatched but not imprinted chicks underwent the same testing procedure, to check for the presence of any spontaneous preference for one or other of the two solid objects. Imprinted chicks approached the 3-D stimulus closely resembling the stimulus they had been exposed to during imprinting (the cone in experiment 1 and the cylinder in experiment 2). Non-imprinted chicks did not show any preference. These results suggest that domestic chicks experience stereokinetic illusions.     

Bidirectional links in the network of multiplication facts

In three experiments, we tested the hypothesis that activation of multiplication operand nodes (e.g., 3 and 8) can occur through presentation of their product (e.g., 24). In Experiments 1 and 2 we found activation of the operands when the product was presented as a cue in a number-matching task. In Experiment 3, activation also occurred in a parity-matching task, where the product (24) was not relevant to the parity matching on its operands (3 and 8). We concluded that bidirectional links exist among the operands and their product for multiplication problems and these links can be activated in a purely stimulus-driven manner. We suggest this may constitute the basis for the solution of simple divisions by mediation through the complementary multiplication facts.     

Number magnitude orients attention, but not against one’s will

Recent evidence has shown that uninformative numbers can trigger attention shifts congruent with the spatial representation of number magnitude (Fischer, Castel, Dodd, & Pratt, 2003). In the present study, three spatial-cuing experiments whose aim was to qualify the automaticity of this numbermediated orienting are described. Experiment 1 replicated the phenomenon, showing that uninformative numbers can evoke orienting in a simple detection task. In Experiment 2, target location was random, but the participants were encouraged to shift attention to the left in response to large numbers and to the right in response to small numbers. No evidence for strong automaticity was observed, since the participants’ performance was better when left-side targets were preceded by large numbers than when they were preceded by small numbers and vice versa. Experiment 3 corroborated this pattern by comparing gaze- and number-mediated cuing under conditions of real counterpredictiveness. The results indicate that unlike gaze-driven orienting, number-mediated orienting is not obligatory.
