Effects of the Positive Action programme on problem behaviours in elementary school students: a matched-pair randomised control trial in Chicago

This study examined the effects of the Positive Action (PA) programme in Chicago Public Schools on problem behaviours among a cohort of elementary school students from grade three through grade five. Using a matched-pair, randomised control design with 14 elementary schools, approximately 510 fifth-graders self-reported lifetime substance use, serious violence-related behaviour, and current bullying and disruptive behaviours. Three-level (i.e. students nested within schools within school pairs) overdispersed Poisson models were used to examine programme effects on the number of items endorsed for each of the four outcomes. Findings indicated that students in the intervention endorsed 31% fewer substance use behaviours (incidence rate ratio [IRR] = 0.69), 37% fewer violence-related behaviours (IRR = 0.63) and 41% fewer bullying behaviours (IRR = 0.59), respectively, compared to students in the control schools. Reduction in reported disruptive behaviours was of a similar magnitude (27%, IRR = 0.73), but was not statistically significant. These results replicate findings of an earlier randomised trial of the PA programme and extend evidence of its effectiveness to youth attending large urban school systems.     

Which preventive interventions effectively enhance depressed mothers' sensitivity? A meta‐analysis

Improving depressed mothers' sensitivity is assumed to be a key element in preventing adverse outcomes for children of such mothers. This meta‐analysis examines the short‐term effectiveness of preventive interventions in terms of enhancing depressed mothers' sensitivity toward their child and investigates what type of intervention is most effective. Thirteen interventions, reported in 10 controlled outcome studies, met the inclusion criteria (N = 918). Meta‐analytic results showed a small to medium, significant mean effect size (g = 0.32) with large variation in individual effect sizes (?0.56–1.76). Interventions including baby massage were highly effective in improving maternal sensitivity (g = 0.85). In contrast, individual therapy for the mother proved ineffective in terms of improving maternal sensitivity (g = ?0.00). Two other significant predictors of greater effect sizes were the inclusion of a support group and the use of a higher number of intervention methods; however, the significance of these results was largely accounted for by one single study. Our meta‐analysis confirms that depressed mothers' sensitivity can be improved by preventive intervention and suggests that baby massage may be an effective intervention method to evoke short‐term changes in maternal sensitivity. It is unclear whether these changes are maintained over time.     

Injustice in physical education: gender and the perception of deprivation in grades and teacher support

School as an institution is not powerful enough to fight external mechanisms leading to gender inequalities. Sport, as Physical Education (PE), remains a male domain and appears as a site for the reproduction of hegemonic masculinity. In PE, girls obtain lower grades than boys; teachers support boys more. This paper focuses upon the French pupils’ perceptions of injustice with respect to teacher support and grades relative to gender and social gender role orientation. Data were collected through questionnaires from 1620 pupils in secondary school. Although boys, Androgynous and Masculine pupils, obtained significantly higher grades in PE, they felt more deprivation. Concerning teacher support, girls’ perceptions of injustice were similar to boys’ perceptions, and Undifferentiated pupils perceived the highest deprivation level. Pupil’s perceptions may not be free of gender stereotypes. Vanessa Lentillon is in the third year of PhD in the Centre de Recherche et d’Innovation sur le Sport (C.R.I.S.).

An experimental investigation of the impact of the Lidcombe Program on early stuttering

Preliminary Phase I and II trials for the Lidcombe Program of early stuttering intervention have found favorable outcomes and that the treatment is safe. Although speech-language pathologists (SLPs) often need to intervene with pre-schoolers' early stuttering, many of these children will recover at some time in the future without such intervention. Consequently, they need to know whether the Lidcombe Program's effect on stuttering is greater than that of natural recovery. Participants were 23 pre-school children who were randomly assigned to either a control group or a treatment group that received the Lidcombe Program for 12 weeks. A repeated measures ANOVA showed no main effect on stuttering for the group (control/treatment), a significant main effect for the measurement occasion (at the start and at the end of the treatment period), and a significant interaction between group and measurement occasion. Stuttering in the treatment group reduced twice as much as in the control group. These results are interpreted to mean that the introduction of the Lidcombe Program has a positive impact on stuttering rate, which exceeds that attributable to natural recovery.     

Cross-modal correlation of auditory and visual language laterality tasks: a serendipitous finding

Two experiments were conducted to investigate whether auditory and visual language laterality tasks test the same brain processes for verbal functions. In the first experiment, 48 undergraduate students (24 males, 24 females) completed both an auditory monitoring task and a visual monitoring task, with the Waterloo Handedness Questionnaire administered between the two tasks. The visual task was an analogue of the dichotic listening task used. It was hypothesized that a significant cross-modal correlation would be found, indicating that the dichotic listening task and the visual analogue task do, in fact, test the same brain processes for verbal functions. Results revealed a right ear advantage in the auditory task, a left visual field advantage (LVFA) in the visual task, and a cross-modal correlation of asymmetries of -.09. The LVFA observed in the visual task was replicated in Experiment 2, thus establishing its legitimacy. Results are discussed in relation with the type of processing that might produce such an unexpected finding on the visual task.     

Differential effects of damage within the hippocampal region on memory for a natural, nonspatial Odor-Odor Association

Debate continues on whether the role of rodent hippocampus in memory is limited to the spatial domain. Recently, this controversy has been addressed with studies on the social transmission of food preference, an odor-odor association task with no spatial requirements. Multiple reports have concluded that damage to the hippocampal region impairs memory in this task, but there remain questions about the extent of damage essential to produce an impairment. Furthermore, a recent study () found no effect of hippocampal lesions on memory in this task. We tested animals with complete lesions of the hippocampus (H) lesions of the hippocampus plus subiculum (HS), and lesions of the adjacent, anatomically related cortices of the parahippocampal region (PHR). H lesions produced an impairment on spatial delayed alternation, but not on memory for the social transmission of food preference, whereas HS and PHR lesions produced severe and equivalent impairments on memory for the socially acquired food preference. We discuss possible explanations for the discrepancy with the results of and conclude that the hippocampus and subiculum together play a critical role in the formation of this form of nonspatial, relational memory.     

A descriptive analysis of baseline and equivalence-class performances under many-to-one and one-to-many structures

The purpose of the present experiment was to describe responding as a function of One-to-Many (OTM) and Many-to-One (MTO) training structures and identify baseline performances correlated with the accuracy level in tests for equivalence class formation. Participants were 42 adults assigned to either the MTO or the OTM groups, trained on 24 baseline relations, and assessed on the emergence of three 9-member equivalence classes. Participants in the MTO group presented similar frequencies of responses to each of the comparisons throughout baseline training. Also, the number of trials required to meet the baseline mastery criterion was negatively correlated with test accuracy. Participants in the OTM group presented more variable frequencies of responses to each of the comparisons (participants tended to select some of the comparisons less often than others at the beginning of the training). In addition, the number of reinforced responses to the node presented as a sample during training was positively correlated with the number of correct responses during testing for the OTM group. The experiment contributed to an in-depth stimulus control analysis of baseline and test performances, and its results have implications for understanding potential sources of variability between the training structures.     

The effects of type of instruction,animacy cues,and dimensionality of objects on the shape bias in 3‐ to 6‐year‐old children

Robust evidence exists for the shape bias, or children's tendency to extend novel names and categorize objects more readily on the basis of shape than on other object features. However, issues remain about the conditions that affect the shape bias and its importance as a linguistic device. In this research, we examined how type of instruction (common noun naming, proper noun naming, same kind, and goes with), animacy of objects (animate, inanimate), and dimensionality of objects (two‐dimensional, three‐dimensional) affect the shape bias in 3‐ to 6‐year‐old children. Overall, all children showed strong use of the shape bias with categorization (same kind, goes with) instructions, the former in line with the shape‐as‐cue theory. Additionally, the shape bias was quite robust in the inanimate condition, regardless of type of instruction or dimensionality of objects. However, in the animate condition, a proper noun naming instruction coupled with an animate object cue reduced the shape bias across both two‐ and three‐dimensional objects. Implications of these findings are presented.

Highlights

• This study assessed the “shape bias,” a linguistic strategy young children routinely use when confronted with the task of extending a novel name from one object to another.
• Novel name extension and categorization tasks were used in this study.
• Shape bias was affected by the type of instructions, animacy of objects, and dimensionality of objects.

     

Clinical Supervision Dilemmas Related to Child Abuse in Wraparound Treatment

We conducted two separate, exploratory studies to evaluate the differences between the supervision of wraparound (in-home) and outpatient (office) child treatment interventions. Study one (n = 96) examined the structure and norms of supervision between groups as well as rates of general disclosure to direct supervisors. Study two (n = 116) specifically examined the frequency of child abuse and neglect encountered in each intervention setting, and the level of disclosure in supervision of these mandatory reporting events. Findings from the first study suggest that wraparound clinicians received significantly less individual supervision and colleague consultation than their office-based counterparts. Additionally, wraparound clinicians were significantly more likely to withhold information about client cases from their direct supervisors. In the second study, wraparound clinicians endorsed significant increases for observed child abuse, observed child neglect, and verbally reported child neglect compared to their office-based counterparts. In regards to mandatory reporting issues with children, wraparound clinicians were found to be significantly less likely to disclose issues pertaining to child neglect to their direct supervisors than office-based clinicians. Our studies show preliminary evidence for a needed increase of individual supervision in wraparound practice, in addition to a greater focus on clinician disclosures related to incidents of child abuse and neglect.     

Time perspective,socioeconomic status,and psychological distress in chronic pain patients

Time perspective (TP) is a fundamental dimension of the psychological construction of time. It refers to a subjective experience and can be defined as the relationship that individuals and groups have with the present, past, and future. Studies have shown that it is interesting to take into account TP in the field of health, especially for the study of the psychological distress (PD) of individuals faced with aversive situations. We conducted a research, which aimed to explore the relationship between TP and PD in patients with chronic pain. A total of 264 first-time patients (72.3% women; mean age = 49 years) at CHU Timone (Marseille) pain center answered a questionnaire included TP, socioeconomic status, pain beliefs (PB), pain characteristics, and sociodemographic characteristics. Using hierarchical regression analyses adjusted to the characteristics of pain, sociodemographic characteristics, and PB, we can observe significant relationships between different components of TP, socioeconomic status, and PD. These results emphasize the importance of TP as psychosocial variable in the analysis of PD in patients with chronic pain. These results also lead us to point out the role of the socioeconomic status that predicts levels of PD.
