The development of arithmetic principle knowledge: How do we know what learners know?

This paper reviews research on learners’ knowledge of three arithmetic principles: Commutativity, Relation to Operands, and Inversion. Studies of arithmetic principle knowledge vary along several dimensions, including the age of the participants, the context in which the arithmetic is presented, and most importantly, the type of knowledge assessment (e.g., application of procedures, evaluation of examples). The vast majority of studies utilize single-faceted knowledge assessments, which can lead to incomplete or misleading views of learners’ knowledge. Both context and type of knowledge assessment can influence conclusions about learners’ arithmetic principle knowledge. However, relatively few studies directly address the possible effects of context or type of knowledge assessment on their results. To move the field forward, research that utilizes multifaceted knowledge assessments is needed.     

Why do women underperform under stereotype threat? Evidence for the role of negative thinking

This study investigated the role of negative thinking as a potential mediator of performance deficits under stereotype threat. After being assigned to a stereotype-threat or a no-threat condition, 60 female participants were asked to complete a difficult math task. Using the thought-listing technique, women under stereotype threat reported a higher number of negative thoughts specifically related to the test and to mathematics compared with women in the no-threat condition. Moreover, women under stereotype threat also showed a sharp decrease in performance that (a) was most pronounced in the second half of the test and (b) was mediated by the increase in negative thinking.     

Are Chinese narcissists disagreeable? Evidence from self‐ and peer‐ratings of agreeableness

Many studies have found that narcissism is negatively related to agreeableness in Western samples. Four experiments explored this relationship in a Chinese population. In Study 1, 228 junior high school students reported their narcissism and Five Factor Personality traits. In Study 2, participants recruited through the internet completed the measures of narcissism and agreeableness. In Study 3, 145 college students completed the measures of narcissism and agreeableness, as well as self‐esteem and social desirability. In Study 4, 204 senior high school adolescents reported their own narcissistic and agreeableness personality traits. They also received peer‐ratings of agreeableness. We found that narcissism was positively related with self‐reported agreeableness (Study 1, 2 and 4), but not with other ratings of agreeableness (Study 4). Chinese narcissists perceived themselves as agreeable, and their self‐perceptions of agreeableness were more positive than their peers rated them. We discuss the current findings in relation to the Chinese cultural context and underscore cultural roots of narcissism.     

Autism,early narcissistic injury and self‐organization: a role for the image of the mother’s eyes?

Holland elucidated the new paradigm of self-organization in complex adaptive systems. This paradigm holds for all living systems, including the personality. In conjunction with the theory of archetypes, self-organization suggests two radical hypotheses, one about early development, the other about the origins of autism. Autism is associated with several medical conditions, with genetic markers, and with infant visual deprivation. However none of these factors is either necessary or sufficient to cause autism. It is hypothesized that each of these factors increases the likelihood of a primary psychological deficit: failure to acquire, or retain, the image of the mother's eyes. This hypothesis was initially derived from analytic work with patients who have early narcissistic injury and with patients who have mild autistic traits. Both diagnoses may arise from the same initial disturbance: Symington argued that autism is an extreme form of infantile narcissism. Indirect evidence for the image-of-the-eyes hypotheses comes from the evolution of primates, from infant-mother observations, from observations of infant vision, and from experiments on vision in other vertebrates. Byrd recently confirmed that the incidence of autism is increasing dramatically. The image-of-the-eyes hypotheses suggest that this increase may be linked to increased use of non-maternal childcare for young infants.     

Under what conditions do children have difficulty in inhibiting imitation? Evidence for the importance of planning specific responses

The response set effect has been observed in a number of developmental tasks that are proposed to required inhibition. This effect has been interpreted as evidence that the specific responses children plan to make in these tasks become prepotent. Here we investigated whether there is a response set effect in the hand game. In this task, children need to suppress imitation and make a fist in response to a finger and point a finger in response to a fist. Following pilot data, we tested 7- and 11-year-olds (N=36, Experiment 1) and then 5- and 6-year-olds (N=40, Experiment 2). A response set effect was observed in the hand game with children 6years of age and older. Thus, we obtained evidence consistent with a domain-general intentional mechanism that modulates prepotency. In the General discussion, we consider how this mechanism may work and how our findings relate to current theories of imitation.     

Positive affectivity and lifestyle in adulthood: do you do what you feel?

There is much evidence for the adaptive value of positive affect. Empirical work examining different facets of positive affect and their consequences for psychological adaptation remains sparse, however. This study (young, middle-aged, and older adults; N = 293) investigated the links between two dimensions of positive affect (positive involvement and pleasant affect) and two lifestyles (hedonic and growth related), each indicated by general value orientations, self-reported everyday activities, and activity aspirations. Structural equation models showed that pleasant affect and positive involvement constitute distinct dimensions evincing different age trends and relating differentially to hedonic and growth-related lifestyles. Specifically, pleasant affect, but not positive involvement, was related to a hedonic lifestyle, whereas positive involvement, and not pleasant affect, was associated with a growth-related lifestyle. These findings underline the importance of considering two dimensions of positive affect--pleasant feelings and positive involvement--separately when studying the link between affect and lifestyle.     

Does medial prefrontal cortex activity during self‐knowledge reference reflect the uniqueness of self‐knowledge?1

Abstract: For this study, functional magnetic resonance imaging was used to examine whether medial prefrontal cortex (MPFC) activity during self‐knowledge reference reflects the uniqueness of self‐knowledge. Experiment 1 investigated neural activity during self‐knowledge reference (“Does the word describe you?”) and self‐monitoring (“Does the word make you feel pleasant?”). The results showed that self‐knowledge reference and self‐monitoring activate common neural substrates within the MPFC. Experiment 2 compared neural activity produced by self‐knowledge reference, other‐knowledge (acquaintance‐knowledge) reference (“Does this word describe the person?”), and evaluation (“Is this word socially desirable?”). Results showed no increase in MPFC activity during self‐knowledge reference relative to other‐knowledge reference. Furthermore, self‐knowledge reference and other‐knowledge reference share common neural substrates within the MPFC. The results described indicate that it is unlikely that MPFC activity during self‐knowledge reference reflects the uniqueness of self‐knowledge. The feature, as reflected in MPFC activity, is discussed.     

Self‐esteem and culture: Differences in cognitive self‐evaluations or affective self‐regard?

Although people from East Asian countries consistently report lower self-esteem than do those from Western countries, the origins of this difference are unclear. We conducted two studies to illuminate this issue. Study 1 found that Chinese participants appraised themselves less positively than American participants on a cognitive measure of self-evaluations, but cultural differences were absent on a measure of affective self-regard. Moreover, cultural differences in global self-esteem were eliminated once cognitive self-evaluations were statistically controlled. Study 2 found that cultural differences in modesty underlie cultural differences in cognitive self-evaluations. These findings suggest that Chinese feel as positively toward themselves as Americans do, but are less inclined to evaluate themselves in an excessively positive manner.     

How do we know what we are doing? Time, intention and awareness of action

Time is a fundamental dimension of consciousness. Many studies of the "sense of agency" have investigated whether we attribute actions to ourselves based on a conscious experience of intention occurring prior to action, or based on a reconstruction after the action itself has occurred. Here, we ask the same question about a lower level aspect of action experience, namely awareness of the detailed spatial form of a simple movement. Subjects reached for a target, which unpredictably jumped to the side on some trials. Participants (1) expressed their expectancy of a target shift during the upcoming movement, (2) pointed at the target as quickly and accurately as possible before returning to the start posiment to the target shift if required and (3) reproduced the spatial path of the movement they had just made, as accurately as possible, to give an indication of their awareness of the pointing movement. We analysed the spatial disparity between the initial and the reproduced movements on those with a target shift. A negative disparity value, or undershoot, suggests that motor awareness merely reflects a sluggish record of coordinated motor performance, while a positive value, or overshoot, suggests that participants' intention to point to the shifting target contributes more to their awareness of action than their actual pointing movement. Undershoot and overshoot thus measure the reconstructive (motoric) and the preconstuctive (intentional) aspects of action awareness, respectively. We found that trials on which subjects strongly expected a target shift showed greater overshoot and less undershoot than trials with lower expectancy. Conscious expectancy therefore strongly influences the experience of the detailed motor parameters of our actions. Further, a delay inserted either between the expectancy judgement and the pointing movement, or between the pointing movement and the reproduction of the movement, had no effect on visuomotor adjustment but strongly influenced action awareness. Delays during either interval boosted undershoots, suggesting increased reliance on a time-limited sensory memory for action. The experience of action is thus strongly influenced by prior thoughts and expectations, but only over a short time period. Thus, awareness of our actions is a dynamic and relatively flexible mixture of what we intend to do, and what our motor system actually does.     

Is regret for inaction relatively self‐enhancing?

Previous accounts of regret suggest that people report greater regret for inaction than for action because the former is longer lasting and more painful than the latter. We suggest instead that the tendency for people's greatest regrets to concern inaction more than action may be due to the relatively self‐enhancing nature of regrets for inaction. In Study 1 we asked people to think about their greatest recent regret and to code it as being due to action or inaction. In Study 2 participants described their greatest regret from across their entire life. In both studies we observed an inaction effect only amongst individuals high in self‐esteem (HSE). In Study 2 we found that the inaction effect was confined to HSE people whose greatest regret was personal in nature. These results support the claim that regret for inaction is relatively self‐enhancing and suggest that the inaction effect found in real‐life regrets may be due, in part at least, to the self‐enhancement goals of HSE individuals.

The ecological validity of the “who said what?” technique: An examination of the role of self‐involvement,cognitive interference and acquaintanceship

Questions are raised about the possible ecological invalidity of the traditional “who said what?” (WSW) procedure. Three studies are reported which use a modified, quasi‐naturalistic version of the WSW technique, in which rather than being passive recipients of presented information, participants instead play an active role in the production of such information in an interactive context. Data are presented that demonstrate that the social categorization effect typically obtained through the traditional WSW procedure generalizes beyond the circumstances in which it was initially demonstrated. Thus, in Study 1 it was established that social categories (gender, in this case) are cognitively used in real interactions between participants in order to organize information. Moreover, Study 2 demonstrated that the use of categories is accentuated when, as is typical in real world situations, recollections are not made immediately after the perception of the relevant stimuli but following a period of intervening cognitive activity. The findings of Study 3, however, suggest that the WSW technique may not inevitably lead to social categorization effects: typical effects did not appear when participants knew each other well, and therefore saw one another as unique, idiosyncratic individuals, rather than as category members.     

Working together or separately? The role of identity and cultural self‐construal in well‐being among Japanese youth

Young people develop a sense of personal identity during the transition to adulthood, a time when individuals choose and adhere to a specific set of goals, values, and beliefs. In addition, in many contemporary Asian societies, youth are expected to acquire and balance traditional and Western cultural views of the self — that is, independent and interdependent self‐construal. To understand the relationships between the personal and cultural facets of the transition to adulthood, this study examined (a) associations between personal identity and well‐being and (b) the possible moderating role of cultural self‐construal (independence and interdependence) in this link. These hypotheses were tested in a sample of 520 Japanese university students (52.6% female). The results indicated that personal identity predicted each dimension of well‐being, suggesting that the importance of personal identity in promoting youth's well‐being can be understood as a universal phenomenon. Moreover, because the moderating role of self‐construal in the links between identity and well‐being was found to be limited, personal identity can be viewed as operating separately from self‐construal in well‐being to a large extent. Implications and suggestions for future research are discussed.     

Where to seat the applicant? How spatial distance influences the effect of self‐promotion on interviewer evaluations

In high‐stakes contexts such as job interviews, people seek to be evaluated favorably by others and they attempt to accomplish such favorable judgments particularly through self‐promotional behaviors. We sought to examine the persuasiveness of job candidates’ self‐promotion by examining job applicants’ subjective hireability from the perspective of construal‐level theory. Construal‐level theory states that perceptions occur from different levels of psychological distance (i.e., distal vs. proximal). This distance is created by other dimensions of distance (e.g., spatial or social distance) and affects how individuals construe incoming information. From a large distance, people more readily process abstract information, whereas from a close distance, people more readily process concrete information. Specifically, construal compatibility occurs when abstract versus concrete features of a stimulus match the psychological distance experienced by message‐recipients. Construal compatibility (vs. incompatibility) makes evaluations (e.g., of messages) more favorable. To apply this principle to self‐promotion, we created self‐promotional videos of a job interview, in which the applicant sat either far away from or close to the hiring manager (manipulating psychological distance); the applicant, then, used either direct or indirect self‐promotion (manipulating message construal level). The results showed participants reported stronger intention to hire the applicant when distance matched (vs. did not match) the type of self‐promotion the applicant used.
