The dynamic functions of social cues during children's word learning

Children learn words in a social environment, facilitated in part by social cues from caregivers, such as eye-gaze and gesture. A common assumption is that social cues convey either perceptual or social information, depending on the age of the child. In this review of research on word learning and social cues during early childhood, we propose that (1) the functions of social cues are not categorically perceptual or social, and (2) social cues support word learning in four interdependent ways: by helping children to orient attention, extract relevant information, disambiguate referents, and understand others' referential intent. We conclude with specific recommendations for theory-building and suggest that the dynamic and complex functions of social cues need to be accounted for in any complete theory of word learning.     

On Halting Meta-argument with Para-Argument

Recourse to meta-argument is an important feature of successful argument exchanges; it is where norms are made explicit or clarified, corrections are offered, and inferences are evaluated, among much else. Sadly, it is often an avenue for abuse, as the very virtues of meta-argument are turned against it. The question as to how to manage such abuses is a vexing one. Erik Krabbe proposed that one be levied a fine in cases of inappropriate meta-argumentative bids (2003). In a recent publication (2022) Beth Innocenti expands on this notion of a penalty, arguing that some meta-arguments should be halted with “shouting, cussing, sarcasm, name-calling.” In this essay, we review Innocenti’s case that these confrontations and haltings improve the argumentative circumstances. We provide three reasons that this promise is not well-founded. First, that such confrontations have a significant audience problem, in that they are more likely to be interpreted as destroying the argumentative context than improving it. Second, that Innocenti’s procedural justification, that those who lose meta-discussions should pay a penalty, is not satisfied if the meta-discussion is halted. And third, there is a boundary problem for the cases, since it seems there is no principled reason to restrict halting meta-arguments just to these cases (especially if there is no meta-discussion on the matter to make the bounds explicit). Though expressions of anger can be appropriate in argument, we argue, it cannot take the place of argument.

     

A semantic memory sentence verification model based on relative judgment theory

A subjective referent model of sentence verification in semantic memory tasks based on the relative judgment theory of Link and Heath (1975), together with the derivation of a discriminability index, are presented in this paper. An attractive feature of the model is its consideration of both error rates and response times (RTs) in the calculation of the discriminability index. The model is also able to account for the frequent finding in semantic memory tasks that error RTs are longer than correct RTs. A partial replication of Experiment 2 of McCloskey and Glucksberg's (1979) sentence verification context effect studies, in which we employed 44 subjects and 28 categories, and controlled for item familiarity, revealed that error RTs were consistently longer than correct RTs--a finding inconsistent with the McCloskey and Glucksberg property comparison model, but in accord with the subjective referent model. An important fortuitous result was the detection of a context effect by the discriminability measure, an effect not detected by the RT data alone. The discriminability measures yielded a near perfect correlation with estimates of the mean step size of the random walk obtained by application of the parameter estimation program FITTRW (Heath, 1983).     

USING ABERRANT BEHAVIORS AS REINFORCERS FOR AUTISTIC CHILDREN

In a series of experiments, we assessed the efficacy of using autistic children's aberrant behaviors as reinforcers to increase their correct task responding. In Experiment 1, reinforcer conditions of stereotypy, food, and varied (food or stereotypy) were compared. In Experiment 2, the conditions were delayed echolalia, food, and varied (food or delayed echolalia), and in Experiment 3, perseverative behavior was compared with stereotypy and food as potential reinforcers. A multielement design was used for all comparisons, and side-effect measures were recorded during and after teaching sessions as well as at home. Results indicated that, in general, task performance was highest when brief opportunities to engage in aberrant behaviors were provided as reinforcers. Edibles were associated with the lowest performance. Furthermore, no negative side effects (e.g., an increase in aberrant behaviors) occurred. The results are discussed in terms of suggesting a more pragmatic treatment approach by addressing the contingent use of autistic children's aberrant behaviors as reinforcers.     

Planning processes in preschool children

This study investigated different types of planning skills in 4- and 5-year-olds. The planning tasks consisted of three search tasks and two clustering tasks. Each task was measured in three ways: by a planning score, the Bronson task attack strategy measure of ongoing behaviors, and by self-report. A varimax rotation of the scores in a factor analysis produced the same two factors for both the planning scores and the Bronson task attack strategy scores. One factor was formed by tasks that allowed for a variety of open-ended solutions, but also had heavy information-processing demands. Tasks that allowed for only one task-imposed solution, but with lighter information-processing demands, formed the second factor. Two of the primary planning tasks used in prior research with preschoolers did not load on the same factor, the grocery store search task (Gauvain & Rogoff, 1989) and the Wellman search task (Wellman, Fabricus, & Sophian, 1985), which suggests that these tasks measure different types of planful search. Self-report data indicated that children were not able to adequately describe their plans. In addition, the one task that required semantic clustering was too difficult for the majority of the preschoolers. Taken together, this suggests that language-based planning measures will underestimate preschoolers' actual planning capacity.     

FURTHER ANALYSIS OF PROBLEM BEHAVIOR IN RESPONSE CLASS HIERARCHIES

A functional analysis identified the reinforcers for 3 participants' problem behavior, but only relatively mild problem behaviors (e.g., screaming, disruption) were observed when all topographies produced tested consequences. We then conducted an extinction analysis in which specific topographies produced a reinforcer while all other topographies were on extinction. The extinction analysis confirmed that the same reinforcer identified in the initial functional analysis maintained more severe topographies of problem behavior (e.g., aggression). In addition, results of the extinction analysis indicated that 2 of the participants displayed patterns of responding consistent with a response class hierarchy hypothesis, in which less severe problem behavior frequently occurred prior to more severe topographies. The 3rd participant displayed a response pattern indicative of differential reinforcement effects.     

Sym-Phenomenologizing: Talking Shop

In this essay I discuss the idea of deploying workshops in phenomenology -- i.e., teaching the discipline by practising it. I focus on the model proposed by Herbert Spiegelberg, the first person to give systematic attention to this idea and the first to institutionalize it over a period of several years. Drawing on my experience in several of the workshops he led at Washington University, St. Louis, I detail the method he recommended in preparation for a workshop I ten led at the inaugural meeting of To the Things Themselves at the University of New Hampshire.     

Latent structure of the Sex-Role Egalitarianism Scale: Confirmatory factor analyses

The dimensionality of alternate forms of the Sex-Role Egalitarianism Scale (SRES) was assessed using confirmatory factor analysis. The subjects, predominantly Caucasian students from seven colleges in the United States and Canada, completed Form B (n = 1,351) and Form K (n = 633) of the instrument. A series of hierarchically nested measurement models was specified and evaluated. A hypothesized two-factor, second-order solution was deemed most appropriate for both forms: a higher order “Intimate Relationship Egalitarianism” factor that subsumes three first-order domain factors (marital, parental, and social-interpersonal-heterosexual roles) and a higher-order “Formal Relationship Egalitarianism” factor that subsumes two first-order domain factors (educational and employment roles). A preliminary report of this study was presented at the annual meeting of the American Psychological Society, June 1995, New York City.
