Predictors of Differential Responding on a Sentence Completion Task in Traumatized Children

Information-processing theories posit that persons who have experienced trauma may have disturbed emotional processing and therefore exhibit an excess of negative responses to otherwise neutral cues. The role of this mechanism in traumatized children has yet to be fully investigated. This study examined the relationship of varied clinical characteristics and theoretically relevant moderating variables to increased trauma related responding on a non-idiographic sentence completion task. One hundred and eighty-nine children (ages 6–17) residing at a residential home between 1996 and 2011 who had experienced physical, emotional and/or sexual abuse were administered a sentence completion task and the Trauma Symptom Checklist for Children (TSCC) shortly after their admission. Three independent raters determined whether sentence completion responses were trauma related (TRR), non-trauma related, or ambiguous. Trauma related responses were then reviewed for either avoidant/denial style responding or loss related responding. The TSCC posttraumatic stress subscale (PTS) was the only subscale that was uniquely related to TRR. A significant interaction between abuse type and PTS was found with sexual abuse moderating the effect of PTS on TRR. Additionally, age at assessment was positively correlated with both TRR and loss related responding. Time since removal from home was negatively correlated with TRR. Gender differences were found for TRR and loss related responding. These findings highlight the empirical relevance of the sentence completion task in clinical research. Results are discussed in terms of their implications for research, assessment, and intervention.     

Functional maturity of brain structures in children aged 7-8 with differing levels of speech development

First graders (aged 7-8) in a public elementary school served as subjects for this study. The structural components of their speech were analyzed to determine speech maturity level; total EEG activity was analyzed to assess the functional maturity of brain structures. Results showed that children with levels of speech below the age norm exhibited abnormal EEG patterns suggesting immaturity of the cerebral cortex and fronto-thalamic regulatory system, as well as impairments in the functioning of the mesodiencephalic structures and nonspecific activation systems. Abnormalities in the functioning of brain regulatory systems and the presence of local abnormalities in EEG activity of deep origin are important factors in determining the severity of functional speech impairments.     

A Lambek Automaton

We define an automata-theoretic counterpart of (type-logical)grammars based on the (associative) Lambek-calculus L, a prominentformalism in computational linguistics. While the usual push-downautomaton (PDA) has the same weak generative power as the L-basedgrammars (Pentus, 1995), there is no direct relationship betweenthe computations of a PDA for some language L and the derivationsof an L-based grammar for L. In the Lambek-automaton, on theother hand, there is a tight relation (1-1) between automatoncomputations and grammar derivations. The automaton exhibitsa novel mode of operation, using hypothetical steps, directlyinspired by the hypothetical reasoning embodied by L.     

Who is a thinker? With age,higher SES American children increasingly associate social status with divisions in labour

This exploratory report investigates how children, aged 6- to 12-years, reason about divisions in labour. It focuses on understanding when in development children might associate higher status groups with intellectual as opposed to physical labour. It explores this question by introducing a sample of mostly mid/high-SES American children to a novel factory setting and then asking them who is likely to have one of two jobs: a ‘builder’ (physical labour), or ‘thinker’ (intellectual labour) job. Older children were more likely than younger children to associate an individual's higher social status with intellectual labour work as opposed to physical labour work. Children also explained their reasoning, and with age their explanations focused more on social factors like the role of access to ‘choices’ or opportunities in shaping the nature of others' work.     

On Pedagogy of Personality Assessment: Application of Bloom's Taxonomy of Educational Objectives

In this article, Bloom's (1956 Bloom, B. (Ed.), Englehart, M. D., Furst, E. J., Hill, W. H., &; Krathwohl, D. R. (1956). Taxonomy of educational objectives: Handbook 1. Cognitive domain. White Plains, NY: Longman. [Google Scholar]) Taxonomy of Educational Objectives, a pedagogical tool that can help instructors of personality assessment to develop effective and student-centered instructional design, is discussed. Bloom's taxonomy provides a progressive sequence of educational objectives used for lesson planning, needs assessment, and measurement of learning outcomes. The taxonomy comprises 6 categories of objectives that are ordered hierarchically, from the simplest to the most advanced. The levels are knowledge, comprehension, application, analysis, synthesis, and evaluation. I explain how the taxonomy can be applied to the teaching of personality assessment and discuss the implications for assessment pedagogy. I provide examples of effective instructional activities, overview the signs of learners at each level, and highlight typical errors that students make in their oral and written work. Strategies to help learners progress to higher order thinking are also addressed.     

Imagining the future: degraded representations of future rewards and events in schizophrenia

Over the course of life, most people work toward temporally distant rewards such as university degrees or work-related promotions. In contrast, many people with schizophrenia show deficits in behavior oriented toward long-term rewards, although they function adequately when rewards are more immediately present. Moreover, when asked about possible future events, individuals with schizophrenia show foreshortened future time perspectives relative to healthy individuals. Here, we take the view that these deficits are related and can be explained by cognitive deficits. We compared the performance of participants with schizophrenia (n = 39) and healthy participants (n = 25) on tasks measuring reward discounting and future event representations. Consistent with previous research, we found that relative to healthy participants, those with schizophrenia discounted the value of future rewards more steeply. Furthermore, when asked about future events, their responses were biased toward events in the near future, relative to healthy participants' responses. Although discounting and future representations were unrelated in healthy participants, we found significant correlations across the tasks among participants with schizophrenia, as well as correlations with cognitive variables and symptoms. Further analysis showed that statistically controlling working memory eliminated group differences in task performance. Together these results suggest that the motivational deficits characteristic of schizophrenia relate to cognitive deficits affecting the ability to represent and/or evaluate distant outcomes, a finding with important implications for promoting recovery from schizophrenia.     

Social influences on ant-dipping acquisition in the wild chimpanzees (Pan troglodytes verus) of Bossou,Guinea, West Africa

We currently have little understanding of the influence of learning opportunity, whether social or environmental, and maternal role on tool-use acquisition in young wild chimpanzees. This study aims to fill this gap by focusing on the acquisition of ant-dipping among chimpanzees of Bossou, Guinea. Ant-dipping is a hazardous tool-use behaviour aimed at army ants (Dorylus spp.). Bossou chimpanzees target these ants both at nests (high risk) and trails (low risk) and employ two techniques to consume them: direct mouthing and pull-through. We present data for 13 mother–offspring pairs (1–10 years old). Mothers with young ≤5 years old dipped significantly more often at trails than at nests, thus minimizing the risk posed to themselves and their young. Infants thus benefited from better conditions to observe and practice ant-dipping. Mothers also varied greatly in their percent time spent ant-dipping and offspring differed in their learning opportunity. Our results suggest that high opportunity young started to observe and perform ant-dipping sooner and were better at ant-dipping than low opportunity young. Although mothers and weaned offspring correlated positively in their percent time spent dipping and proficiency, they did not match in technique used or tool length. Finally, we propose that the learning trajectory of young may predict individual and sex differences in adulthood. This study demonstrates the important role of mothers and learning opportunity in the acquisition of a hazardous tool-use behaviour and suggests that chimpanzee material culture is a product of a complex interaction between social processes and ecological factors.
