Behavioral Microanalysis of Helping Interactions Between Mothers and Adult Children with Mental Retardation

Although direct observation has provided much information regarding caregiver-care recipient interactions, our understanding of the applications of this technique remains incomplete. This study expands upon earlier observational work by examining adults with mental retardation (MR) and their family caregivers in the home setting. Specialized computer software was used to conduct real-time observation and recording of interactional styles of maternal caregivers of eight younger (M = 23 years old) and eight older (M = 49 years old) MR adults during two cognitive tasks: block design and card sorting. Differences in the amount and type of assistance provided by the caregiver were examined by coding the occurrence and duration of seven interactional behaviors. The results demonstrated that the caregivers of the younger adults used more positive statements and modeling/gestural prompts, whereas the caregivers of the older adults provided more physical assistance and performed more of the tasks themselves. More importantly, this project provided information regarding interactions between MR adults and their maternal caregivers and demonstrated the utility of computer-assisted data collection technology with a community-based, nondemented population.     

Infant vocal development during the first 6 months: speech quality and melodic complexity

The early development of infant non‐distress vocalizations was investigated in this study. Thirteen infants, from 4 to 24 weeks of age, and their mothers were observed weekly in a face‐to‐face interaction situation. The speech quality (syllabic versus vocalic) and melodic complexity (simple versus complex) of infant vocalizations were coded independently. Based on speech quality and melodic complexity, four types of infant non‐distress vocalizations were categorized: simple and complex syllabic (speech‐like) vocalizations as well as simple and complex vocalic (non‐speech‐like) vocalizations. Results showed that complex syllabic sounds were of longer duration and complex vocalic sounds were less frequent than the other types of vocalizations. Curvilinear developmental trends were found in the rate of simple vocalic sounds and in the mean duration of complex syllabic sounds. Furthermore, before 4 months of age, vocalic sounds were more likely to be associated with simple melodic contours, after which syllabic sounds were more likely to be associated with complex melodic contours. A dynamic systems perspective on the early development of infant vocalization is discussed. Copyright © 2000 John Wiley & Sons, Ltd.     

Sequential effects in facial expression categorization

Facial expressions are highly dynamic signals that are rarely categorized as static, isolated displays. However, the role of sequential context in facial expression categorization is poorly understood. This study examines the fine temporal structure of expression-based categorization on a trial-to-trial basis as participants categorized a sequence of facial expressions. The results showed that the local sequential context provided by preceding facial expressions could bias the categorical judgments of current facial expressions. Two types of categorization biases were found: (a) Assimilation effects-current expressions were categorized as close to the category of the preceding expressions, and (b) contrast effects-current expressions were categorized as away from the category of the preceding expressions. The effects of such categorization biases were modulated by the relative distance between the preceding and current expressions, as well as by the different experimental contexts, possibly including the factors of face identity and the range effect. Thus, the present study suggests that facial expression categorization is not a static process. Rather, the temporal relation between the preceding and current expressions could inform categorization, revealing a more dynamic and adaptive aspect of facial expression processing.

Organizational Innovation Climate and Creative Outcomes: Exploring the Moderating Effect of Time Pressure

Time pressure, one of the factors of organizational innovation climate, has an inconsistent effect on employee creativity. Based on the interactional approach, this study attempted to describe time pressure as a moderator. Data were collected from two surveys of R&D employees at Taiwanese national research institutions in 2007 and 2009. The results showed that time pressure moderated the relationship between organizational innovation climate and creative outcomes. As most theorists had predicted, in a strong organizational innovation climate, time pressure hindered creative outcomes. However, as many practitioners advocate, time pressure enhanced creative outcomes in a weak organizational innovation climate. The implications in a time pressure/organizational innovation climate matrix are discussed.     

Children with Specific Language Impairment are not impaired in the acquisition and retention of Pavlovian delay and trace conditioning of the eyeblink response

Three converging lines of evidence have suggested that cerebellar abnormality is implicated in developmental language and literacy problems. First, some brain imaging studies have linked abnormalities in cerebellar grey matter to dyslexia and specific language impairment (SLI). Second, theoretical accounts of both dyslexia and SLI have postulated impairments of procedural learning and automatisation of skills, functions that are known to be mediated by the cerebellum. Third, motor learning has been shown to be abnormal in some studies of both disorders. We assessed the integrity of face related regions of the cerebellum using Pavlovian eyeblink conditioning in 7–11 year-old children with SLI. We found no relationship between oral language skills or literacy skills with either delay or trace conditioning in the children. We conclude that this elementary form of associative learning is intact in children with impaired language or literacy development.     

The Efficacy of a Group Triple P (Positive Parenting Program) for Chinese Parents with a Child Diagnosed with ADHD in Hong Kong: A Pilot Randomised Controlled Study

The present pilot study evaluated the efficacy of the Level 4 Group Positive Parenting Program (Triple P) with Hong Kong Chinese parents who had a child with attention deficit/hyperactivity disorder (ADHD), using a randomised controlled trial design. It was a mixed research method involving quantitative measurement and semi‐structured focus group. Participants were randomly assigned to Triple P (n = 8) or control group (n = 9) and completed measures on child disruptive behaviours, sense of parenting efficacy and satisfaction, family stress and service needs. Outcomes were assessed at pre‐, post‐, and 3‐month follow‐up. A focus group was also conducted with the participants in the intervention group upon the programme completion. Compared with the control group, the intervention group reported a significant reduction in intensity of child behaviour problems and a significant increase in parenting efficacy at post‐intervention. The gain in reducing intensity of child disruptive behaviours maintained to 3 months after the completion of programme. Qualitative data suggested the three key elements to help both parents and children get positive changes: understanding and empathy, emotional control, and persistence in applying positive parenting strategies. The results partially provided preliminary evidence supporting the efficacy of Triple P in reducing child behaviour problems for ADHD in Chinese society.     

A threshold theory account of psychometric functions with response confidence under the balance condition

The study of thresholds for discriminability has been of long‐standing interest in psychophysics. While threshold theories embrace the concept of discrete‐state thresholds, signal detection theory discounts such a concept. In this paper we concern ourselves with the concept of thresholds from the discrete‐state modelling viewpoint. In doing so, we find it necessary to clarify some fundamental issues germane to the psychometric function (PF), which is customarily constructed using psychophysical methods with a binary‐response format. We challenge this response format and argue that response confidence also plays an important role in the construction of PFs, and thus should have some impact on threshold estimation. We motivate the discussion by adopting a three‐state threshold theory for response confidence proposed by Krantz (1969, Psychol. Rev., 76, 308–324), which is a modification of Luce's (1963, Psychol. Rev., 70, 61–79) low‐threshold theory. In particular, we discuss the case in which the practice of averaging over order (or position) is enforced in data collection. Finally, we illustrate the fit of the Luce–Krantz model to data from a line‐discrimination task with response confidence.     

The Dialogue of Ḥikma: Generating Harmony in Muslim–Non-Muslim Relations

This article seeks to explain the concept of the dialogue of ?ikma as a qur'anic principle in developing harmony in Muslim–non-Muslim relations. Living together harmoniously is essential in a community made up of a myriad of cultures and religions. Efforts to create harmony can be realized through the dialogue of ?ikma and by inculcating it as the culture in daily life interaction. This is truly essential in the context of mixed-faith families. In order to explore how the dialogue of ?ikma can be applied in Muslim–non-Muslim relations, this article examines the experience of Muslim converts living together with their non-Muslim families of origin. The research was conducted through in-depth interviews with selected Muslim converts from a variety of cultural backgrounds, living in the area of Kota Kinabalu, Sabah. The results indicate that Muslim converts share similar experiences in applying the dialogue of ?ikma as a mechanism for solving family problem arising as a result of conversion to Islam.
