This commentary considers the paper by Furley and Memmert (2010) who sought to test the respective validities of the specific processing and cognitive adaptation hypotheses. That they found no evidence of a difference between experienced basketball players and nonathletes on the Corsi block task, a measure of spatial memory, led them to infer support for the specific processing hypothesis, namely that differences between experts and novices manifest themselves only in processes related specifically to the domain of expertise. An alternative interpretation is offered, indicating possible confounds and referring to recent research that suggests Corsi block and dynamic spatial tasks depend upon different neuronal networks.  相似文献

Children tell prosocial lies for self- and other-oriented reasons. However, it is unclear how motivational and socialization factors affect their lying. Furthermore, it is unclear whether children’s moral understanding and evaluations of prosocial lie scenarios (including perceptions of vignette characters’ feelings) predict their actual prosocial behaviors. These were explored in two studies. In Study 1, 72 children (36 second graders and 36 fourth graders) participated in a disappointing gift paradigm in either a high-cost condition (lost a good gift for a disappointing one) or a low-cost condition (received a disappointing gift). More children lied in the low-cost condition (94%) than in the high-cost condition (72%), with no age difference. In Study 2, 117 children (42 preschoolers, 41 early elementary school age, and 34 late elementary school age) participated in either a high- or low-cost disappointing gift paradigm and responded to prosocial vignette scenarios. Parents reported on their parenting practices and family emotional expressivity. Again, more children lied in the low-cost condition (68%) than in the high-cost condition (40%); however, there was an age effect among children in the high-cost condition. Preschoolers were less likely than older children to lie when there was a high personal cost. In addition, compared with truth-tellers, prosocial liars had parents who were more authoritative but expressed less positive emotion within the family. Finally, there was an interaction between children’s prosocial lie-telling behavior and their evaluations of the protagonist’s and recipient’s feelings. Findings contribute to understanding the trajectory of children’s prosocial lie-telling, their reasons for telling such lies, and their knowledge about interpersonal communication.  相似文献

This paper describes how different self‐construals influence people's perception of temporal distance and in turn their task evaluation. We hypothesize that people with a more accessible interdependent (vs. independent) self‐construal perceive future events as temporally more proximal, and that people's reaction toward a task is intensified when the temporal distance to the task matches (vs. mismatches) their self‐construal. Across four studies, we showed that individuals with a more accessible interdependent self‐construal (Study 1) and East Asians (Study 2) perceived future events as more proximal than those with a more accessible independent self‐construal and European Americans. Further, when considering a task at a temporal distance that fits their self‐construal, individuals perceived a pleasant task as more motivating (Study 3) and an unpleasant task as less motivating (Study 4).

This article examines the role that personality variables and processes play in people's efforts to manage their public images. Although most research on self-presentation has focused on situational influences, people differ greatly in the degree to which they care about others' impressions of them, the types of impressions they try to convey, and their evaluations of their self-presentational effectiveness. Personality constructs such as public self-consciousness, approval motivation, and fear of negative evaluation are associated with the motive to manage one's impressions, and people who differ in self-disclosure and desire for privacy differentially reveal information about themselves to others. Other variables relating to people's self-concepts, interpersonal goals, and traits influence the construction of specific images. Finally, the extent to which people believe they are capable of making desired impressions influences their impression management strategies and how they respond to other people's evaluations.  相似文献

Part representation is not only critical to object perception but also plays a key role in a number of basic visual cognition functions, such as figure-ground segregation, allocation of attention, and memory for shapes. Yet, virtually nothing is known about the development of part representation. If parts are fundamental components of object shape representation early in life, then the infant visual system should give priority to parts over other aspects of objects. We tested this hypothesis by examining whether part shapes are more salient than cavity shapes to infants. Five-month-olds were habituated to a stimulus that contained a part and a cavity. In a subsequent novelty preference test, 5-month-olds exhibited a preference for the cavity shape, indicating that part shapes were more salient than cavity shapes during habituation. The differential processing of part versus cavity contours in infancy is consistent with theory and empirical findings in the literature on adult figure-ground perception and indicates that basic aspects of part-based object processing are evident early in life.  相似文献

Two brief intervention studies tested whether teaching students to mentally contrast a desired future with its present reality resulted in better academic performance than teaching students to only think about the desired future. German elementary school children (N = 49; Study 1) and US middle school children (N = 63; Study 2) from low-income neighborhoods who were taught mental contrasting achieved comparatively higher scores in learning foreign language vocabulary words after 2 weeks or 4 days, respectively. Results have implications for research on the self-regulation of commitment to solve assigned tasks in classroom settings, and for increasing academic performance in school children in low-income areas.  相似文献

An historically important conception of the unity of science is explanatory reductionism, according to which the unity of science is achieved by explaining all laws of science in terms of their connection to microphysical law. There is, however, a separate tradition that advocates the unity of science. According to that tradition, the unity of science consists of the coordination of diverse fields of science, none of which is taken to have privileged epistemic status. This alternate conception has roots in Otto Neurath’s notion of unified science. In this paper, I develop a version of the coordination approach to unity that is inspired by Neurath’s views. The resulting conception of the unity of science achieves aims similar to those of explanatory reductionism, but does so in a radically different way. As a result, it is immune to the criticisms facing explanatory reductionism. This conception of unity is also importantly different from the view that science is disunified, and I conclude by demonstrating how it accords better with scientific practice than do conceptions of the disunity of science.  相似文献

Mosaic chromosomal abnormalities are relatively common. However, mosaicism may be missed due to multiple factors including failure to recognize clinical indications and order appropriate testing, technical limitations of diagnostic assays, or sampling tissue (s) in which mosaicism is either not present, or present at very low levels. Blood leukocytes have long been the “gold standard” sample for cytogenetic analysis; however, the culturing process for routine chromosome analysis can complicate detection of mosaicism since the normal cell line may have a growth advantage in culture, or may not be present in the cells that produce metaphases (the lymphocytes). Buccal cells are becoming increasingly utilized for clinical analyses and are proving to have many advantages. Buccal swabs allow for simple and noninvasive DNA collection. When coupled with a chromosomal microarray that contains single nucleotide polymorphic probes, analysis of buccal cells can maximize a clinician’s opportunity to detect cytogenetic mosaicism. We present three cases of improved diagnosis of mosaic aberrations using buccal specimens for chromosomal microarray analysis. In each case, the aberration was either undetectable in blood or present at such a low level it likely could have gone undetected. These cases highlight the limitations of certain laboratory methodologies for identifying mosaicism. We also present practice implications for genetic counselors, including clinic workflow changes and counseling approaches based on increasing use of buccal samples.  相似文献

Parental presence is often employed to alleviate distress in children within the context of surgery under general anesthesia. The critical component of this intervention may not be the presence of the parent per se, but more importantly the behaviors in which the parent and child engage when the parent is present. The purpose of the current study was to examine the sequential and reciprocal relationships between parental behaviors and child distress during induction of general anesthesia. Participants were 32 children (3–6 years) receiving dental surgery as a day surgery procedure, and their parents. A modified Child Adult Medical Procedures Interaction Scale-Revised was used to code parent and child behaviors. Initial child distress led to increased parental provision of reassurance and decreased provision of physical comfort. Our findings may inform the development of preoperative preparation programs whereby parents can be appropriately educated about what behaviors will be helpful/unhelpful for their child during induction of general anesthesia.  相似文献
