Armstrong and Vogel (2009) proposed that the differences between self-efficacy and interests are a matter of measurement artifact rather than substance. In tests of this hypothesis, they conceived of self-efficacy and interest as observed indicators of larger RIASEC (Realistic, Investigative, Artistic, Social, Enterprising, and Conventional) types…

Objective: To evaluate whether a dichotic memory test would reveal deficits in short-term working-memory recall and long-term memory recall in a group of adult patients with ADHD. Methods: A dichotic memory test with ipsilateral backward speech distraction in an adult ADHD group (n = 69) and a control group (n = 66) is used to compare performance…

Research examining the links between disorganized attachment and clinical symptoms largely has neglected middle childhood due to lack of available measurement tools. The few studies that have examined these links in other developmental phases have found higher clinical symptoms in disorganized individuals. Our study extended this research by using…

The National Science Education Standards prescribe that an understanding of the importance of classifying organisms be one component of a student's educational experience in the life sciences. The use of a classification scheme to identify organisms is one way of addressing this goal. We describe Conifer ID, a computer application that assists…

A wealth of empirical evidence has now accumulated concerning animals' categorizing photographs of real-world objects. Although these complex stimuli have the advantage of fostering rapid category learning, they are difficult to manipulate experimentally and to represent in formal models of behavior. We present a solution to the representation…

This paper presents the author's response to Xiaoming Xi's article titled "How do we go about investigating test fairness?" In this response, the author focuses on test fairness and Toulmin's model of argument structure, Xi's proposal, and the challenges the proposal brings. Xi proposes an approach to investigating test fairness to guide…

The influence of listener's expertise and sound identification on the categorization of environmental sounds is reported in three studies. In Study 1, the causal uncertainty of 96 sounds was measured by counting the different causes described by 29 participants. In Study 2, 15 experts and 15 nonexperts classified a selection of 60 sounds and…

The numerous temperament and personality constructs in childhood impede the systematic integration of findings on how these individual differences relate to developmental psychopathology. This paper reviews the main temperament and personality theories and proposes a theoretical taxonomy representing the common structure of both temperament and…

Although course assignments require English as a Second Language (ESL) teacher candidates to design activities, performance assessments, and lessons that balance the teaching of the English language and academic content, the ESL teacher candidates remain perplexed as to how to teach without a prescribed curriculum. The answer is challenging, given…

Commissioner's Rules Concerning the State Plan for Educating English Language Learners (ELLs) states that all school districts that are required to provide bilingual education and/or English as a second language (ESL) programs establish and operate a Language Proficiency Assessment Committee (LPAC). The LPACs are charged with reviewing all…

By definition, all of the stimuli in an equivalence class have to be functionally interchangeable with each other. The present experiment, however, demonstrated that this was not the case when using post-class-formation dual-option response transfer tests. With college students, two 4-node 6-member equivalence classes with nodal structures of…

Do conceptual categories affect basic visual processing? A conceptual grouping effect for familiar stimuli is reported using a visual search paradigm. Search through conceptually-homogeneous non-targets was faster and more efficient than search through conceptually-heterogeneous non-targets. This effect cannot be attributed to perceptual factors…

Rule-based and information-integration category learning were compared under minimal and full feedback conditions. Rule-based category structures are those for which the optimal rule is verbalizable. Information-integration category structures are those for which the optimal rule is not verbalizable. With minimal feedback subjects are told whether…

Building on normative conceptualisations of multifunctionality as a decision-making spectrum bounded by productivist and non-productivist action and thought, this paper analyses farm-level multifunctional agricultural transitions. First, the paper suggests that it may be possible to categorise different farm types along the…

J. Schumpeter is a key figure, even a seminal one, on technological innovation. Most economists who study technological innovation refer to Schumpeter and his pioneering role in introducing innovation into economic studies. However, despite having brought forth the concept of innovation in economic theory, Schumpeter provided few if any analyses…
