Parent Beliefs about Treatment Credibility and Effectiveness: Assessment and Relation to Subsequent Treatment Participation

We assessed parents’ beliefs about treatment credibility and effectiveness and examined the influence of these beliefs on subsequent treatment participation. Seventy-six parents completed the Credibility/Expectancies Questionnaire—Parent Version (CEQ-P), and subsequently participated in treatment for their child's clinically referred conduct problems. The key findings were that: (a) the CEQ-P is composed of two components that measure parents’ treatment credibility and expectancies; (b) the total scale and each component are internally consistent and have strong test-retest reliability; (c) scores on the CEQ-P are significantly associated with scores on a measure of parent motivation for treatment, supporting the construct validity of this measure; and (d) scores on the CEQ-P at the first clinic visit significantly predict subsequent adherence to treatment procedures above and beyond demographic variables and parent motivation for treatment. This study provides an efficient and psychometrically sound measure of parent beliefs about treatment and demonstrates the importance of such beliefs for subsequent treatment adherence.     

Speciation of Superions from Humans: Is Species Cleansing the Ultimate Form of Terror and Genocide?

Using ideas from evolution, and what is known about higher stages of development, we examine a hypothetical scenario, in which new humanoid species, called Superions, are produced. What would then happen with current humans? Recent genetic engineering advances have led to creating life forms with particular characteristics. Scientists are already genetically engineering human beings. Some changes are to improve health. Engineering of traits such as intelligence, higher stage reasoning or less neuroticism is also very likely. This is seen as the ultimate terrorist act because it is genocide, not against a culture, but against an entire species. The article will also discuss how Homo Sapiens could defend themselves against this. Relating two species (systems), the Homo Sapiens and Superions constitutes metasystematic operations. Developing a system of discourse that would not destroy the Homo-sapiens requires paradigmatic operations (Sonnert and Commons, Individ Soc 4:31–35, 1994).     

Stereotype threat and test performance: A primer for school psychologists

Ethical guidelines require school psychologists to ensure that their assessment practices are nondiscriminatory, but typical discussions on this topic neglect the possible discriminatory effects of cultural stereotypes on assessment results. Recent research on stereotype threat shows that students' knowledge of stereotype-based negative expectations about their test performance can depress their actual test performance. This paper discusses the range of conditions that promote stereotype threat and identifies important moderators and mediators of the phenomenon. Several practical suggestions are offered for school psychologists to consider when interviewing students, interpreting assessment results, and developing programs to increase schoolwide achievement.     

Application scenarios for nonstandard log-linear models

In this article, the authors have 2 aims. First, hierarchical, nonhierarchical, and nonstandard log-linear models are defined. Second, application scenarios are presented for nonhierarchical and nonstandard models, with illustrations of where these scenarios can occur. Parameters can be interpreted in regard to their formal meaning and in regard to their magnitude. The interpretation of the meaning of parameters is the main focus of this article. Design matrices are used to describe the hypotheses tested in models and to illustrate cases in which parameters are interpretable. Also, design matrices are used to show where and how nonstandard models differ from standard hierarchical models. Coding schemes are discussed, in particular, dummy coding and effects coding. Data examples are given with data and models discussed in the literature.     

Adding up the effects of cultural experience on the brain

How does the brain represent number and perform mathematical calculations? According to a recent and provocative study by Tang and colleagues, it depends on which language you learn. They found that the divergent linguistic and cultural experiences of native Chinese and native English speakers are associated with distinct patterns of brain activity during mathematical processing. Their results raise important questions about the cognitive and neural specificity of cultural influences on mathematical processes and the core nature of mathematical cognition.     

How to Tell If a Particular Memory Is True or False

ABSTRACT— How can you tell if a particular memory belonging to you or someone else is true or false? Cognitive scientists use a variety of techniques to measure groups of memories, whereas police, lawyers, and other researchers use procedures to determine whether an individual can be believed or not. We discuss evidence from behavioral and neuroimaging studies and research on lying that have attempted to distinguish true from false memories.     

The development of depth perception from motion parallax in infancy

North Dakota State University, Fargo, North Dakota Little is known about infants' perception of depth from motion parallax, even though it is known that infants are sensitive both to motion and to depth-from-motion cues at an early age. The present experiment assesses whether infants are sensitive to the unambiguous depth specified by motion parallax and, if so, when this sensitivity first develops. Eleven infants were followed longitudinally from 8 to 29 weeks. Infants monocularly viewed a translating Rogers and Graham (1979) random-dot stimulus, which appears as a corrugated surface to adult observers. Using the infant-control habituation paradigm, looking time was recorded for each 10-sec trial until habituation, followed by two test trials: one using a depth-reversed and one using a flat stimulus. Dishabituation results indicate that infants may be sensitive to unambiguous depth from motion parallax by 16 weeks of age. Implications for the developmental sequence of depth from motion, stereopsis, and eye movements are discussed.     

Age differences in learning from text: Evidence for functionally distinct text processing systems

We investigated the influence of sentence elaboration on self‐regulated learning in order to examine age differences in resource allocation to the construction of textbase‐ and discourse‐level representations. Older and younger adults learned about a topic by reading a series of sentences varying in elaboration (from simple factoids to highly elaborated text) and manner of presentation (progressive change in elaboration vs. random change in elaboration). Younger readers were more likely to recall information from factoids; older adults, from highly elaborated text. Relative to young, older readers showed an advantage in the progressive presentation condition, which minimised frequent changes between textbase‐ and discourse‐level processing. Older adults showed poorer memory monitoring for factoids and less elaborated discourse relative to young, but when passages were highly elaborated or presented progressively, age differences were eliminated. Results support the idea that textbase‐ and discourse‐level encoding arise from functionally distinct systems whose regulation depends on text properties and reader age.
