This set of studies examined the ability of 3-year-olds to conceptualize multiple pretend identities with objects. Rather than relying on verbal response measures, as has been done in the past, children's creative and inferential pretend actions were used as indicators of their understanding. The common structure to all four studies was that…

Association models constitute an attractive alternative to the usual log-linear models for modeling the dependence between classification variables. They impose special structure on the underlying association by assigning scores on the levels of each classification variable, which can be fixed or parametric. Under the general row-column (RC)…

Many kinds of common and easily observed causal relations exhibit property transmission, which is a tendency for the causal object to impose its own properties on the effect object. It is proposed that property transmission becomes a general and readily available hypothesis used to make interpretations and judgments about causal questions under…

Inexact measurements can have devastating effects in sciences where precision is of paramount importance. In contrast, morphological sciences rely heavily on description, comparison, and estimation to make meaningful inferences about the structure of humans and other animals. A review of the 1918 edition of "Gray's Anatomy" shows that the tendency…

Using a representational momentum paradigm, this study investigated the hypothesis that judgments of how far another agent's head has rotated are influenced by the perceived gaze direction of the head. Participants observed a video-clip of a face rotating 60[degrees] towards them starting from the left or right profile view. The gaze direction of…

Many studies have established that children tend to exclude objects for which they already have a name as potential referents of novel words. In the current study we asked whether this exclusion can be triggered by social-pragmatic context alone without pre-existing words as blockers. Two-year-old children watched an adult looking at a novel…

The voice is a marker of a person's identity which allows individual recognition even if the person is not in sight. Listening to a voice also affords inferences about the speaker's emotional state. Both these types of personal information are encoded in characteristic acoustic feature patterns analyzed within the auditory cortex. In the present…

L. Wilkinson and the Task Force on Statistical Inference (1999) recommended reporting confidence intervals for measures of effect sizes. If the sample size is too small, the confidence interval may be too wide to provide meaningful information. Recently, K. Kelley and J. R. Rausch (2006) used an iterative approach to computer-generate tables of…

When children hear an object referred to with a label that is moderately discrepant from its appearance, they frequently make inferences about that object consistent with the label rather than its appearance. We asked whether 3-year-olds actually believe these unexpected labels (i.e., conversion) or whether their inferences simply reflect a desire…

Inferences are important because not everything in the text is explicit. Therefore, the reader must generate inferences that fill in "missing" information. Various factors can influence inference processes, including those that are related to the text and reader. Moreover, these two factors are likely to interact in highly complex ways,…

Helping students better understand how scientists reason and argue to draw scientific conclusions has long been viewed as a critical component of scientific literacy, thus remains a central goal of science instruction. However, differences of opinion persist regarding the nature of scientific reasoning, argumentation, and discovery. Accordingly,…

Decision-making involves the ability to choose between competing actions that are associated with uncertain benefits and penalties. The Iowa Gambling Task (IGT), which mimics real-life decision-making, involves learning a reward-punishment rule over multiple trials. Patients with damage to ventromedial prefrontal cortex (VMPFC) show deficits…

Holland's (1997) theory of corresponding person and work environment structures was evaluated by comparing the integration of individual and occupational ratings of interests, abilities, and skills. Occupational ratings were obtained from the U.S. Department of Labor's O*NET database (U.S. Department of Labor, 2007). College students (494 women,…

This study investigated children's understanding of unfamiliar noun and verb definitions in tasks that were manipulated for syntactic and semantic properties of definitions. The study was also designed to examine the relation between understanding word definitions and the skills of syntactic awareness and making inferences. A total of 117 children…

Purpose: In the 2nd decade of life, language skills expand in both quantitative and qualitative ways. The etiology of these new skills and the relationships among them have been little explored. Method: Taking advantage of widespread access to inexpensive and fast Internet connections in the United Kingdom, we administered four Web-based measures…
