Object-initial clauses (OCs) are associated with more processing difficulties than subject-initial clauses (SCs) in a number of languages (e.g. English, German and Finnish), but a supportive context can reduce or neutralize the difference between SCs and OCs with respect to reading times. Still, it is unresolved how context can affect the…

In a glance, the visual system can provide a summary of some kinds of information about objects in a scene. We explore how summary information about "orientation" is extracted and find that some representations of orientation are privileged over others. Participants judged the average orientation of either a set of 6 bars or 6 circular…

Miller (1956) identified his famous limit of 7 plus or minus 2 items based in part on absolute identification--the ability to identify stimuli that differ on a single physical dimension, such as lines of different length. An important aspect of this limit is its independence from perceptual effects and its application across all stimulus types.…

High-accuracy Global Positioning System (GPS) has become an important geoscientific tool used to measure ground motions associated with plate movements, glacial movements, volcanoes, active faults, landslides, subsidence, slow earthquake events, as well as large earthquakes. Complex calculations are required in order to achieve high-precision…

Preschoolers' ability to make judgments of learning (JOLs) was examined in 3 experiments in which they were taught proper names for animals. In Experiment 1, when judgments were made immediately after studying, nearly every child predicted subsequent recall of every name. When judgments were made after a delay, fewer showed this response tendency.…

In this paper I analyze the role of hindsight in narrative configuration. Configuration means the grasping together of disparate elements into a coherent whole. I argue that hindsight, importantly, brings the temporal constraints on what we can know to the fore, but is a double-edged sword. On the one hand, hindsight is an indispensable tool both…

Axe (2008) speculated that some instances of intraverbal responding might be associated with limited or delayed acquisition because they require discrimination of multiple components of verbal stimuli. Past studies suggest that acquisition of responses under control of complex, multicomponent antecedent stimuli (e.g., conditional or compound…

Polytomous attributes, particularly those defined as part of the test development process, can provide additional diagnostic information. The present research proposes the polytomous generalized deterministic inputs, noisy, "and" gate (pG-DINA) model to accommodate such attributes. The pG-DINA model allows input from substantive experts…

This article examines two methodological issues regarding ways of obtaining and analyzing outcome data for people with intellectual disabilities: (a) self-report and proxy-report data and (b) analysis of population-based data sets. Some people with intellectual disabilities have difficulties with self-reporting due to problems of understanding and…

Natural languages contain many layers of sequential structure, from the distribution of phonemes within words to the distribution of phrases within utterances. However, most research modeling language acquisition using artificial languages has focused on only one type of distributional structure at a time. In two experiments, we investigated adult…

This study examined whether preschool children are able to identify the source of new knowledge that they acquired in a stimulating, interactive learning context. Sixty 4- to 5-year-old children participated in two staged learning events. Several days later, children were asked questions that assessed their knowledge of factual information…

A single experiment is reported in which introductory psychology students were administered a multiple-choice test on psychology with either 4 (n = 78) or 5 alternatives (n = 92) prior to any lectures being delivered. Two answers were generated for each question: a small answer consisting of their favorite alternative, and a large answer…

This study examined the dimensionality of 10 different calibration measures using confirmatory factor analysis (CFA). The 10 measures were representative of five interpretative families of measures used to assess monitoring accuracy based on a 2 (performance) x 2 (monitoring judgment) contingency table. We computed scores for each of the measures…

In organizational and educational practices, sensitivity reviews are commonly advocated techniques for reducing test bias and enhancing fairness. In the present paper, results from two studies are reported which investigate how effective individuals are at detecting problematic test content and the influence such content has on important testing…

Do infants, like adults, consider both the probability of falling and the severity of a potential fall when deciding whether to cross a bridge? Crawling and walking infants were encouraged to cross bridges varying in width over a small drop-off, a large drop-off, or no drop-off. Bridge width affects the probability of falling, whereas drop-off…
