Effects of referential ambiguity,time constraints and addressee orientation on the production of morphologically complex words

In five experiments, participants were asked to describe unambiguously a target picture in a picture–picture paradigm. In the same-category condition, target (e.g., water bucket) and distractor picture (e.g., ice bucket) had identical names when their preferred, morphologically simple, name was used (e.g., bucket). The ensuing lexical ambiguity could be resolved by compound use (e.g., water bucket). Simple names sufficed as means of specification in other conditions, with distractors identical to the target, completely unrelated, or geometric figures. With standard timing parameters, participants produced mainly ambiguous answers in Experiment 1. An increase in available processing time hardly improved unambiguous responding (Experiment 2). A referential communication instruction (Experiment 3) increased the number of compound responses considerably, but morphologically simple answers still prevailed. Unambiguous responses outweighed ambiguous ones in Experiment 4, when timing parameters were further relaxed. Finally, the requirement to name both objects resulted in a nearly perfect ambiguity resolution (Experiment 5). Together, the results showed that speakers overcome lexical ambiguity only when time permits, when an addressee perspective is given and, most importantly, when their own speech overtly signals the ambiguity.     

Weber's Law influences numerical representations in rhesus macaques (Macaca mulatta)

We present the results of two experiments that probe the ability of rhesus macaques to match visual arrays based on number. Three monkeys were first trained on a delayed match-to-sample paradigm (DMTS) to match stimuli on the basis of number and ignore continuous dimensions such as element size, cumulative surface area, and density. Monkeys were then tested in a numerical bisection experiment that required them to indicate whether a sample numerosity was closer to a small or large anchor value. Results indicated that, for two sets of anchor values with the same ratio, the probability of choosing the larger anchor value systematically increased with the sample number and the psychometric functions superimposed. A second experiment employed a numerical DMTS task in which the choice values contained an exact numerical match to the sample and a distracter that varied in number. Both accuracy and reaction time were modulated by the ratio between the correct numerical match and the distracter, as predicted by Weber's Law.     

The influence of provocateurs' emotion displays on the social information processing of children varying in social adjustment and age

This study examined the effect of provocateurs' emotion displays on first through fourth graders' social information processing (SIP). Rating and nomination sociometric techniques were used to identify rejected-aggressive, rejected-nonaggressive, average-nonaggressive, and popular-nonaggressive groups. Children viewed videotaped ambiguous provocation situations in which provocateurs' emotion displays were varied systematically. After each vignette, children's recall of story details, attribution of intent, and problem-solving responses were obtained. Half of the children were randomly assigned to a condition where they were asked directly about provocateurs' emotions, and the remaining children were not asked about provocateurs' feelings. Results revealed both developmental and social adjustment differences in SIP. In addition, provocateurs' emotion displays and asking versus not asking about those displays influenced multiple aspects of SIP.     

A Longitudinal Study of Child Maltreatment, Mother–Child Relationship Quality and Maladjustment: The Role of Self-Esteem and Social Competence

This study examined the concurrent and longitudinal relations of mother-child relationship quality, self-esteem, social competence, and maladjustment among maltreated (n = 206) and nonmaltreated (n = 139) school-aged children from low-income families. Results of the path analysis using structural equation modeling revealed that maltreatment at Time 1 was related to internalizing and externalizing symptomatology at Time 1, both directly as well as indirectly, through its influence on social competence at Time 1. Regardless of maltreatment status, secure mother-child relationship quality was negatively related to internalizing symptomatology at Time 1 and to internalizing and externalizing symptomatology at Time 2 via its influence on self-esteem at Time 1. The results are discussed as suggestive of the role of self-esteem and social competence as mediating mechanisms in the link between relational risks and children's maladjustment.     

Infants' understanding of false labeling events: the referential roles of words and the speakers who use them

The four studies reported here examine whether 16-month-old infants' responses to true and false utterances interact with their knowledge of human agents. In Study 1, infants heard repeated instances either of true or false labeling of common objects; labels came from an active human speaker seated next to the infant. In Study 2, infants experienced the same stimuli and procedure; however, we replaced the human speaker of Study 1 with an audio speaker in the same location. In Study 3, labels came from a hidden audio speaker. In Study 4, a human speaker labeled the objects while facing away from them. In Study 1, infants looked significantly longer to the human agent when she falsely labeled than when she truthfully labeled the objects. Infants did not show a similar pattern of attention for the audio speaker of Study 2, the silent human of Study 3 or the facing-backward speaker of Study 4. In fact, infants who experienced truthful labeling looked significantly longer to the facing-backward labeler of Study 4 than to true labelers of the other three contexts. Additionally, infants were more likely to correct false labels when produced by the human labeler of Study 1 than in any of the other contexts. These findings suggest, first, that infants are developing a critical conception of other human speakers as truthful communicators, and second, that infants understand that human speakers may provide uniquely useful information when a word fails to match its referent. These findings are consistent with the view that infants can recognize differences in knowledge and that such differences can be based on differences in the availability of perceptual experience.     

Adrenocortical reactivity and social competence in seven year-olds

We examined temporal changes in salivary cortisol in response to a peer self-presentation task in a group of seven year-olds, some of whom scored high, average, and low on the Harter, 1983 Perceived Social Competence Scale. Salivary cortisol was measured pre-task, and 20 and 35 min post-task. We found a significant relation between individual differences in perceived social competence and salivary cortisol reactivity in response to the task. Children who perceived themselves as socially competent exhibited a significantly greater decrease in salivary cortisol from 20 to 35 min following the task compared with children who self-reported a relatively lower degree of social competence. We speculate on the meaning of salivary cortisol changes in childrens socio-emotional development.     

Making Decisions About Life-Sustaining Medical Treatment in Patients With Dementia

The problem of decision-making capacity in patients with dementia, such as those with early stage Alzheimer's, can be vexing, especially when these patients refuse life-sustaining medical treatments. However, these patients should not be presumed to lack decision-making capacity. Instead, an analysis of the patient's decision-making capacity should be made. Patients who have some degree of decision-making capacity may be able to make a choice about life-sustaining medical treatment and may, in many cases, choose to forgo treatment.     

Influence Opportunities and the Development of Argumentation Competencies in Childhood

Whether argumentation competencies are associated with the kind of influence opportunities children have in their lives is the focus of this study. The hypothesis is that when children have the opportunity to initiate and evaluate arguments, hear others make and examine arguments, and participate equally in resolving disputes, children are able to develop their argument skills. Four argumentation competencies associated with critical discussions of proposals are identified: creating consensus about problematic situations, advocating proposals, facilitating behavioral commitment, and integrating identities. Second, fourth, and sixth grade children completed tasks that assessed their influence opportunities and argument competencies. Children who perceived themselves to have many collaborative influence opportunities, that is, opportunities in which they could engage in mutual influence, had more highly developed argument competencies than children who did not have such opportunities. As predicted, this relationship occurred with the argument competencies of problem conception, proposal advocacy and facilitating commitment. Measures of non-collaborative influence opportunities were not associated with argument competencies. Together, the results suggest that discussions in which children are given the opportunity to influence and be influenced with arguments may provide the best context for children to develop their argument skills.     

The Client Cultural Competence Inventory: An Instrument for Assessing Cultural Competence in Behavioral Managed Care Organizations

The rapid growth in Behavioral Managed Care Organizations has led to increasing concern about the future availability of culturally competent mental health services for ethnic minorities. Prior efforts to assess cultural competence of mental health services have focused exclusively on agency providers and individual mental health professionals rather than on clients' perceptions of care. We introduce the Client Cultural Competence Inventory, which has several advantages over other cultural competence measures including its (a) lower susceptibility to social desirability bias, (b) ability to assess attitudes concerning a broader range of therapists, providers and plans, and (c) focus on clients rather than the psychiatric community as the central force in determining cultural competence. Preliminary psychometric analyses of the inventory are presented from data gathered in a group of parents with children who are severely emotionally disturbed.     

Relationship between orientation toward multicultural competence,multicultural competent behaviors,and working alliance: Examining a multigroup mediation model

In this study, the researchers examined the relationship among an orientation toward multicultural counseling competence, multicultural competent behaviors, and the working alliance from the perspective of 574 client participants across various therapeutic dyads. There was a positive relationship between clients’ perspectives on counselors’ multicultural orientation, counselors’ multicultural competent behavior, and working alliance. Multicultural competent behaviors mediated the relationship between an orientation toward multicultural competence and working alliance. However, the mediated effect was inconsistent across cross and similar racial/ethnic therapeutic dyads. Implications for counselors, limitations of the study, and future directions for research are provided.
