The role of inferences about referential intent in word learning: evidence from autism

Young children are readily able to use known labels to constrain hypotheses about the meanings of new words under conditions of referential ambiguity. At issue is the kind of information children use to constrain such hypotheses. According to one theory, children take into account the speaker's intention when solving a referential puzzle. In the present studies, children with autism were impaired in monitoring referential intent, but were equally successful as normally developing 24-month-old toddlers at mapping novel words to unnamed items under conditions of referential ambiguity. Therefore, constraints that lead the child to map a novel label to a previously unnamed object under these circumstances are not solely based on assessments of speakers' intentions.     

An evaluation of a brief multiple-stimulus preference assessment with adolescents with emotional-behavioral disorders in an educational setting

Brief multiple-stimulus-without-replacement (MSWO) preference assessments were conducted with 3 adolescent boys with emotional-behavioral disorders in the context of their public school educational program. The reinforcing effects of stimuli identified as high, medium, and low preference were then evaluated using an alternating treatments design in which, following an initial baseline, stimuli were delivered contingent on on-task behavior. High-preference stimuli produced the highest percentages of on-task behavior for all 3 participants.     

Using brief experimental assessment of reading interventions for identification and treatment of a vocal habit

An 11-year-old boy presented in an outpatient clinic with a vocal habit that occurred during reading and conversation. A brief reading assessment was conducted to determine an effective intervention to decrease the habit. A modified version of the word error-correction procedure resulted in positive changes and was implemented by his mother during home reading practices. Significant decreases in the rate of vocal habit were observed during home reading probes, generalization probes, and follow-up.     

A Review of Self-Management Interventions Targeting Academic Outcomes for Students with Emotional and Behavioral Disorders

The purpose of this review was to report on the effectiveness and focus of academic self-management interventions for children and adolescents with emotional and behavioral disorders. Twenty-two studies published in 20 articles and involving 78 participants met inclusionary criteria. The overall mean effect size (ES) across those studies was 1.80 (range –0.46 to 3.00), indicating effects were generally large in magnitude and educationally meaningful. Self-monitoring interventions were the predominant type of self-management technique used by researchers. The mean ES for intervention types were self-evaluation (1.13), self-monitoring (1.90), strategy instruction techniques (1.75), self-instruction techniques (2.71), and multiple-component interventions (2.11). Interventions targeted improvement in math calculation skills more than any other area. The mean ES by academic area were math interventions (1.97), writing (1.13), reading (2.28), and social studies (2.66). There was evidence to support a claim of the generalization and maintenance of findings. Implications, limitations, and areas for future research are discussed.     

A Comparison of Results and Acceptability of Functional Behavioral Assessment Procedures with a Group of Middle School Students with Emotional/Behavioral Disorders (E/BD)

There is currently controversy over the validity and applicability of functional behavioral assessment (FBA) procedures with students with emotional/behavioral disorders (E/BD). A set of FBA procedures, including teacher and student interviews and direct classroom observations, were carried out with eight students with disabilities (7 classified E/BD, one classified LD). Results indicated that when all three methods (teacher/student interviews, classroom observations) yielded a ranking for a function they agreed 64% of those occasions. For those situations in which there was overall disagreement there was agreement between teacher interview and classroom observations most of the time. Social validity data indicated that both students and teachers felt that the assessment procedures were a useful and productive process.     

Parent Perception of Elementary School Aged Children’s Sleep Problems

Wide discrepancies exist concerning the reported occurrence of sleep problems for elementary school children. We describe parental perception of sleep problem behavior in elementary school aged children 5–12 years. Approximately 4% of parents reported their children experienced significant global sleep problems serious enough to adversely affect family functioning. Significant specific sleep problems reported by parents occurred for approximately 9–14% of the children in the sample. These ranges were in the low end of the ranges of sleep problems reported in previous literature for this age group.     

Homeopathic remedies as placebo alternatives — verification on the example of treatment of menopause-related vegetative and emotional disturbances

With the example of treatment of menopause-related vegetative and emotional disturbances, the author verifies the effectiveness of the use of Ignatia amara containing complex homeopathic remedies (IACCHR) as an alternative to placebo. Substantial improvement in psychological and psychosomatic symptoms was observed. Climacteric complaints diminished or disappeared completely in the majority of women (95.7% by patient evaluation and 96.2% by physician evaluation). Compared to standard pharmaceuticals, IACCHR treatment was tolerated better and lower risk of side effects was observed. The results obtained in this work indicate the significant therapeutic potential of this group of treatments, which is in line with the therapeutic effect of the placebo. Nevertheless, the showing of specific effects in pharmacological tests disqualifies the investigated treatments from use in a clinical trial in place of a placebo. An earlier version of this paper was presented at an international conference, “Placebo: Its Action and Place in Health Research Today,” held in Warsaw, Poland on 12–13 April, 2003.     

Validity of the Eating Disorder Examination Questionnaire (EDE-Q) in screening for eating disorders in community samples

In order to examine the concurrent and criterion validity of the questionnaire version of the Eating Disorders Examination (EDE-Q), self-report and interview formats were administered to a community sample of women aged 18-45 (n = 208). Correlations between EDE-Q and EDE subscales ranged from 0.68 for Eating Concern to 0.78 for Shape Concern. Scores on the EDE-Q were significantly higher than those of the EDE for all subscales, with the mean difference ranging from 0.25 for Restraint to 0.85 for Shape Concern. Frequency of both objective bulimic episodes (OBEs) and subjective bulimic episodes (SBEs) was significantly correlated between measures. Chance-corrected agreement between EDE-Q and EDE ratings of the presence of OBEs was fair, while that for SBEs was poor. Receiver operating characteristic (ROC) analysis, based on a sample of 13 cases, indicated that a score of 2.3 on the global scale of the EDE-Q in conjunction with the occurrence of any OBEs and/or use of exercise as a means of weight control, yielded optimal validity coefficients (sensitivity = 0.83, specificity = 0.96, positive predictive value = 0.56). A stepwise discriminant function analysis yielded eight EDE-Q items which best distinguished cases from non-cases, including frequency of OBEs, use of exercise as a means of weight control, use of self-induced vomiting, use of laxatives and guilt about eating. The EDE-Q has good concurrent validity and acceptable criterion validity. The measure appears well-suited to use in prospective epidemiological studies.     

Beliefs in personality disorders: a test with the personality disorder belief questionnaire

The hypothesis that each personality disorder (PD) is characterized by a specific set of beliefs was tested in a sample of 643 subjects, including non-patient controls, axis-I and axis-II patients, diagnosed with SCID-I and -II interviews. Beliefs of six PDs (avoidant, dependent, obsessive-compulsive, paranoid, histrionic, borderline) were assessed with the Personality Disorder Belief Questionnaire (PDBQ). Factor analyses supported the existence of six hypothesized sets of beliefs. Structural equation modeling (SEM) supported the hypothesis that each PD is characterized by a specific set of beliefs. Path coefficients were however in the medium range, suggesting that PDs are not solely determined by beliefs. Nevertheless, empirically derived cutoff scores of the six belief subscales were reasonably successful in classifying subjects, percentages ranging form 51% to 83%. It appeared that there was a monotonical increase in scores on each belief subscale from non-patient controls, to patients without any PD, to patients with PDs (other than the pertinent PD), to patients with the pertinent PD. This suggests that PD-related beliefs are at least partly associated with (personality) psychopathology in general. Another explanation is that many patients' position on the underlying dimensions is not high enough to lead to a DSM PD diagnosis, but high enough to lead to an elevated belief score.     

Free Łukasiewicz and Hoop Residuation Algebras

Hoop residuation algebras are the {, 1}-subreducts of hoops; they include Hilbert algebras and the {, 1}-reducts of MV-algebras (also known as Wajsberg algebras). The paper investigates the structure and cardinality of finitely generated free algebras in varieties of k-potent hoop residuation algebras. The assumption of k-potency guarantees local finiteness of the varieties considered. It is shown that the free algebra on n generators in any of these varieties can be represented as a union of n subalgebras, each of which is a copy of the {, 1}-reduct of the same finite MV-algebra, i.e., of the same finite product of linearly ordered (simple) algebras. The cardinality of the product can be determined in principle, and an inclusion-exclusion type argument yields the cardinality of the free algebra. The methods are illustrated by applying them to various cases, both known (varieties generated by a finite linearly ordered Hilbert algebra) and new (residuation reducts of MV-algebras and of hoops).
