Increased attention to the relationships between affect and learning has led to the development of machine-learned models that are able to identify students' affective states in computerized learning environments. Data for these affect detectors have been collected from multiple modalities including physical sensors, dialogue logs, and logs of…

Student models for adaptive systems may not model collaborative learning optimally. Past research has either focused on modeling individual learning or for collaboration, has focused on group dynamics or group processes without predicting learning. In the current paper, we adjust the Additive Factors Model (AFM), a standard logistic regression…

In Florida, mean proficiency scores are reported on the Florida Comprehensive Achievement Test (FCAT) as well as recommended learning gains from the developmental scale score. Florida now has another within-year measure of growth in reading comprehension from the Florida Assessments for Instruction in Reading (FAIR). The FAIR reading comprehension…

This article provides an in-depth case study analysis of a pilot project organized by the section "Strategic Analysis" of the Belgian Federal Police. Using the Delphi method, which is a judgmental forecasting technique, a panel of experts was questioned about future developments of crime, based on their expertise in criminal or social…

Past research suggests that a categorical event is perceived to be more likely if its subcases are explicitly delineated or "unpacked." In 6 studies, we find that unpacking can often make an event seem less likely, especially when the details being unpacked are already highly accessible. Process evidence shows that the provision of…

The objective of the present article is to show that connectionist simulations can be used to model some of the socio-cognitive processes underlying the learning of the norm of internality. For our simulations, we developed a connectionist model which we called NetNorm (based on Dual-Network formalism). This model is capable of simulating the…

On the basis of earlier findings, we (Fiedler & Kareev, 2006) presented a statistical decision model that explains the conditions under which small samples of information about choice alternatives inform more correct choices than large samples. Such a small-sample advantage (SSA) is predicted for choices, not estimations. It is contingent on high…

A critical concern for college teachers is that their students understand the material covered in class. Students need to be aware of what they know and what they do not know. This awareness is actually one component of metacognition and specifically involves being able to accurately assess one's own level of understanding of material. Some…

This study examined whether improvement in parents' depression was linked with changes in their children's depressive symptoms and functioning. Participants were 223 parents and children ranging in age from 7 to 17 years old (M = 12.13, SD = 2.31); 126 parents were in treatment for depression and 97 parents were nondepressed. Children were…

We investigated the mechanisms by which fillers, such as "uh" and "um", affect memory for discourse. Participants listened to and attempted to recall recorded passages adapted from "Alice's Adventures in Wonderland". The type and location of interruptions were manipulated through digital splicing. In Experiment 1, we tested a processing time…

Conceptions of well-being are cognitive representations of the nature and experience of well-being. These conceptions can be described generally by the degree to which hedonic and eudaimonic dimensions are emphasized as important aspects of the experience of well-being. In two studies, the prediction that eudaimonic dimensions of individual…

Purpose: We sought to confirm predictions based on past findings that pretreatment mean length of utterance (MLU) would predict which of 2 grammatical treatments would best facilitate generalized and maintained grammatical development in preschoolers with specific language impairment (SLI). Method: The participants were 57 preschoolers with SLI. A…

Hippocampal subfields CA3 and CA1 are hypothesized to differentially support the generation of associative predictions and the detection of associative mismatches, respectively. Using high-resolution functional MRI, we examined hippocampal subfield activation during associative retrieval and during subsequent comparisons of memory to matching or…

The focus of this article was employment creation by developing forest park tourism industries in China. Analysis of the statistical data and an input-output approach showed that 1 direct job opportunity in tourism industries created 1.15 other job opportunities. In the high, middle, and low scenarios, the total predicted employment in forest park…

Response to stress is determined in part by genetically influenced regulation of the monoamine system (MAOA). We examined the interaction of a stressor (receipt of public assistance) and a gene regulating MAOA in the prediction of change in adolescent depressive symptoms and body mass index (BMI). Participants were drawn from the National…
