Infants’ responses to objects representing levels of word knowledge and categorical information

The effects of differing levels of word knowledge on infants’ sequential touching behaviors were investigated in two studies. In both, parent report was used to assess three levels of word knowledge: known, frontier, and unknown. In the first study, 14-month-old infants sequentially touched objects consistent with parents’ reports of their word knowledge. In the second study, 20-month-old infants sequentially touched objects by both conceptual category and reported level of word knowledge. It appears that even infants, like adults, can make distinctions among objects on the basis of their knowledge about the objects’ labels.     

When is ignorance bliss? The effects of inaccurate self-assessments of knowledge on learning and attrition

Two studies were conducted to examine the implications of inaccurate self-appraisals in online training. Self-assessment of knowledge moderated the effects of trainees’ performance on subsequent performance and attrition. Performance was highest after uniformly positive ratings (i.e., high self-assessment and high performance), followed by underestimation, overestimation, and uniformly negative ratings, respectively. Attrition was lowest after uniformly positive ratings, followed by underestimation, uniformly negative ratings, and overestimation, respectively. Effort had a more positive effect on performance following low than high self-assessments and this interaction fully mediated the self-assessment/performance interaction on subsequent performance. Commitment had a more negative effect on subsequent attrition following low than high self-assessments and this interaction fully mediated the self-assessment/performance interaction on subsequent attrition. Finally, trainee conscientiousness affected their behavior when their performance and self-assessments were inconsistent—overestimating and underestimating performance increased attrition more for trainees low in conscientiousness and impaired performance more for trainees high in conscientiousness.     

Children's response to sales promotions and their impact on purchase behavior

Despite the growth in children's purchasing power, surprisingly little is known about how children respond to sales promotions. We conduct two experiments to address this issue. Study 1 shows that elementary-aged (second and fifth grade) children's purchase decisions are influenced by the presence of sales. Study 2 demonstrates that both age groups favor conceptually easier promotions, even when the sale is inferior. Additionally, we find that children have difficulty applying mathematical concepts to sales promotions, regardless of classroom mastery of the associated operations. Together, these results indicate that elementary-aged children routinely incorporate sales into purchase decisions, sometimes with suboptimal results.     

Maternal Expressive Style and Children's Emotional Development

Maternal expressive styles, based on a combination of positive and negative expressive patterns, were identified at two points in time and related to multiple aspects of preschool children's emotional development. Mother–child pairs from 260 families participated when the children were 3 years old, and 240 participated again at aged 4 years. Expressive styles were identified at age 3 using cluster analysis, replicated at age 4 and examined in relation to children's emotional understanding, expressiveness and regulation. Three expressive styles were identified: high positive/low negative, very low positive/average negative and average positive/very high negative. Cluster membership was stable in 63% of families from age 3 to 4 years; no systematic patterns of change were evident in the remaining families. Expressive style was related to aspects of children's emotional expression at 3 years and to emotion expression and regulation at 4 years. Children's expressiveness and regulation at age 3 were also related to changes in mothers' expressive styles over 1 year. Identifying mothers' expressive styles provides a unique way to understand the potential role of the emotional climates in which preschool‐aged children learn to express and regulate their own emotions.

The shadow of familiarity: a contributor to the intersubjective field

This paper examines the influence of familiarity on the progress of analysis. It is proposed that familiarity is a particular aspect of the intersubjective field which emerges over time and begins to shape and influence the behaviours, perceptions, thoughts, and feelings of the participants. It is also proposed that states of familiarity can have facilitative or defensive functions in an analytic relationship and that it is an influence co-created in the field. The experience of familiarity operates as background to our various foreground concerns in analytic work and therefore exists primarily as an implicit, rather than explicit, experience in analysis. Defensive familiarity often creates a feeling of relatedness that is subtly unrelated, a form of pseudo-intimacy. Parallels between defensive familiarity and related concepts are examined including defences against the unknown, role responsiveness, romantic love, the image of the stranger, and unformulated experience. This paper concludes with two case examples and a discussion of procedural knowledge in the implicit domain as an explanatory framework for the understanding of familiarity states in the analytic setting.     

Effects of Conflict Resolution Training Integrated Into a High School Social Studies Curriculum

Abstract

The authors examined the effectiveness of conflict resolution and peer mediation training among California high school students. The authors randomly assigned 2 of 4 classes to receive 5 weeks of conflict resolution and peer mediation training integrated into the required social studies curriculum. The remaining 2 classes studied the same social studies curriculum for an identical amount of time (105 min every other day) without conflict resolution and peer mediation training. The authors investigated 2 issues. The 1st was the effectiveness of the conflict resolution and peer mediation training. The trained students, compared with the untrained students, learned the integrative negotiation and peer mediation procedures better, applied the procedures more completely, chose an integrative over a distributive approach to negotiation, and developed more positive attitudes toward conflict. The 2nd issue was the impact of the training program on academic achievement. Integrating conflict resolution and peer mediation training into an academic course promoted higher achievement, greater long-term retention of the academic learning, and greater transfer of academic learning in social studies to language arts.     

Modeling,Truth, and Philosophy

Knowledge requires truth, and truth, we suppose, involves unflawed representation. Science does not provide knowledge in this sense but rather provides models, representations that are limited in their accuracy, precision, or, most often, both. Truth as we usually think of it is an idealization, one that serves wonderfully in most ordinary applications, but one that can terribly mislead for certain issues in philosophy. This article sketches how this happens for five important issues, thereby showing how philosophical method must take into account the idealized nature of our familiar conception of truth.     

Justification is potential knowledge

This paper will articulate and defend a novel theory of epistemic justification; I characterize my view as the thesis that justification is potential knowledge (JPK). My project is an instance of the ‘knowledge-first’ programme, championed especially by Timothy Williamson. So I begin with a brief recapitulation of that programme.     

Knowledge despite falsehood

I examine the claim, made by some authors, that we sometimes acquire knowledge from falsehood. I focus on two representative cases in which a subject S infers a proposition q from a false proposition p. If S knows that q, I argue, S's false belief that p is not essential to S's cognition. S's knowledge is instead due to S's belief that p′, a proposition in the neighbourhood of p that S (dispositionally) believes (and knows). S thus knows despite her false belief. The widely accepted and plausible principle that inferential knowledge requires known premises is unscathed.     

Relation of occupational knowledge to career interests and competence perceptions in Italian children

The relations of differential occupational knowledge with interests and competence perceptions in children as well as how these relations were moderated by gender and grade were examined in this study using an Italian sample. Data were collected from samples of elementary school and middle school children (N = 539). The Inventory of Children's Activities—Revised (ICA-R; Tracey & Ward, 1998) was used to assess children's interest and competency perceptions in various activities associated with the Holland's RIASEC types. The Occupational Knowledge Scale (OKS) was created for this study, and consisted of a representative sampling of occupational titles to which children indicated their knowledge. Hierarchical regression results indicated a relationship between knowledge, interests, and competence perceptions in children. With regard to overall knowledge, no relationship was found between general knowledge and either grade or gender. More specific examination of the type of knowledge as it varied across the dimensions of People–Things, and Data–Ideas demonstrated that there appeared to be a specific pattern relating interest, gender, and grade to knowledge of occupations. For knowledge of people relative to things occupations, higher interest, higher grade level, and being female predicts stronger knowledge of people occupations. It was also found that interest in ideas predicts stronger knowledge of ideas occupations, and being male predicts stronger knowledge of high prestige occupations. Generally, competence perceptions did not have a unique relation with one's knowledge of People–Things, Ideas–Data, or Prestige; however, girls who reported higher competence had greater knowledge of ideas occupations.
