Sentence comprehension and production in children with cochlear implants: Errorless procedures and equivalence-based instruction

Research supports equivalence-based instruction (EBI) and matrix training for increased listening and speaking skills in children with cochlear implants (CI). We incorporated errorless procedures to optimize the EBI and evaluated the effects on the auditory comprehension and verbal responding at-sentences level in six CI children who were readers and showed inaccurate tacting. Subject-verb-object sentences were arranged in two matrices; diagonal combinations were trained and evaluated non-diagonal combinations. EBI included stimulus fading and exclusion to directly teach the dictated sentence-picture matching; written-sentences construction upon dictation also was taught. Probes assessed the derived stimulus-stimulus and stimulus-response relations. All participants learned the auditory-visual discriminations and the exclusion resulted in fewer errors than on a stimulus fading procedure. Five participants formed equivalence classes and increased verbal responding to equivalent stimuli, especially pictures tacting. They also showed recombinative generalization for both matrices. Professionals can incorporate errorless procedures to EBI for improving sentence comprehension, tacting, and productivity in CI children.     

Evaluating the desirability of meals: an illustrative multiattribute decision analysis procedure to assess portfolios with interdependent items

This paper presents an exploratory study designed to address complex scaling problems in applying value/utility theory to measuring preferences over alternative combinations (or portfolios) of multiattributed items. This application considers meals served to nursing home residents as portfolios of food items and seeks to maximize meal appeal. We consider food interrelation and link single food measurements to overall meal measurements in the process of constructing meal desirability scales. We test the resulting scales to capture one expert's professional judgments and discuss issues raised in this specific application in the context of general portfolio evaluation problems. © 1998 John Wiley & Sons, Ltd.     

The mediation component of the hopelessness depression in relation to negative life events

A necessary test of the mediational processes component of the hopelessness theory of depression is to test whether the individuals who have negative attributional style and experience negative life events are likely to make negative attributions for the negative events they confront. The present study, using undergraduate students, find that the negative attributional style do not predict negative attributions subjects made for the negative life events they experience within a period of 3 months. However, subjects' negative attributions for the negative life events coupled with the experience of a high number of negative life events predicted their depressive symptomatology. The depressive symptomatology is found not to be mediated through hopelessness. The findings are discussed in relation to the hopelessness theory of depression.     

OTS: A program for converting Noldus Observer data files to SDIS files

A program for converting Noldus Observer data files (ODF) to sequential data interchange standard (SDIS) files is described. Observer users who convert their data files can then take advantage of various flexible and powerful data modification and computational procedures available in the Generalized Sequential Querier, a program that assumes SDIS-formatted files.     

Contextual framing of loss impacts harm avoidance during risky spatial decisions

Although the same decision to act can occur in multiple contexts, how these contexts differentially influence behavior is not well understood. In this paper, we investigate whether contextual framing affects individuals' behavior in spatial decision making. Although previous research suggests that individuals' judgments are sensitive to contextual (and particularly moral) factors of a scenario, no work has addressed whether this effect extends to spatial decisions. To investigate the impact of context on perceptual sensorimotor behavior, we superimposed two moral dilemmas (which we call help and harm) on a spatial decision-making paradigm. The basic task required participants select a target area while avoiding an overlapping nontarget area. Although the visuospatial task was constant, the moral context was changed when participants had to execute either a drone missile strike on enemies in the harm context or deliver ammunition to allies in the help context. Participants more strongly avoided losses in the harm context, reflected by a greater selection bias away from the nontarget (i.e., allies) on drone strike trials. These findings suggest that the contextual framing of a subjective perceived loss on a spatial decision can drive avoidant motor execution behavior.     

Maternal perinatal representations and their associations with mother–infant interaction and attachment: A longitudinal comparison of Portuguese and Brazilian dyads

Prior research in Western countries (mostly the US, Canada and northern Europe) indicates that mothers' representations are associated with mother–infant interaction quality and their child's attachment security later in the first year. Fewer studies, however, have evaluated whether these associations hold for mother–infant dyads in other countries, such as Brazil and Portugal. Although these countries share a similar language and culture, they differ on societal dimensions that may affect parenting attitudes and mother–infant relationships, such as economic stress, social organisation, social policy, and the availability of services for young families. In this longitudinal study, we followed two independent samples of Brazilian and Portuguese mother–infant dyads from the perinatal period to 12 months post-partum. We assessed mothers' perinatal representations using semi-structured interviews in the first 48 hours after the infant's birth, and evaluated the associations of these representations with mother interaction quality at 9 months and infant attachment at 12 months. Results were similar in each country, corroborating prior research in single Western countries: Mothers with more positive perinatal representations were more sensitive to their infants during free play at 9 months and were more likely to have infants classified as securely attached at 12 months.     

Family Functioning among Rural Teens and Caregivers: Interactive Influence on Teen Dating Violence

Multi-informant assessment of family functioning is considered best practice in research and clinical settings. However, in the area of teen dating violence, multi-informant assessment of family functioning has received limited attention. The current study investigated whether and to what extent caregiver and adolescent perceptions of family functioning interact in their influence on adolescent dating violence. Participants were 493 adolescents and their primary caregivers from a rural southeastern community in the United States. As hypothesized, a paired-samples t test showed that adolescents’ scores on the family functioning measure were significantly lower than their caregivers’ scores. Logistic regressions revealed that adolescents’ positive views of family functioning were significantly associated with a lower likelihood of dating violence victimization but not perpetration and that caregivers’ views on family functioning moderated the impact of adolescent-reported family functioning on both dating violence outcomes. Post hoc analyses showed that adolescents with negative perceptions of family environment were most likely to be victims and perpetrators of dating violence when their parents also reported more negative views of family environment. The article concludes with a discussion of how these findings can: (a) advance our understanding of the impact of family functioning on teen dating relationships and (b) inform practical efforts aimed at preventing dating aggression among teens.
