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.

Reversal of the preference reversal phenomenon

The widely replicated preference reversal phenomenon (PRP) violates most theories of decision under risk. People exhibiting PRP choose a safe bet (with a large chance of a small gain) over a long shot (with a small chance of a larger gain). But, when bidding to buy or sell each bet, they bid more for the long shot. Surprisingly, in Experiment 1, a new opposite reversal pattern (NPRP) was found: Safe bets typically received larger bids than long shots and reversals were far more frequent when the long shot was chosen. In Experiment 2, NPRP was found for $100 expected value bets, but PRP occurred for bets with $3 expected values. The task characteristics apparently necessary to produce NPRP are (1) bids in the form of maximum buying prices, (2) possibility of loss in bidding, but not in choice, and (3) large payoffs. It is argued that wealth effects predicted by expected utility theory are too small to explain NPRP. Instead, it is hypothesized that a contingent decision process underlies the shift in reveral patterns and that aspiration levels exert increased influence in bidding to buy when payoffs are large.     

The effect of training procedures on the overlearning reversal effect in young children

The performance of 80 preschool children on a reversal problem was studied as a function of amount of training and type of training procedure used during acquisition and reversal. In the extinction phase of reversal learning, subjects given a correction procedure during the reversal problem made fewer perseverative errors than subjects given noncorrection. In the reversal midplateau phase of reversal learning, overtraining facilitated reversal learning for subjects receiving noncorrection during the acquistion problem, but not for subjects receiving correction. A shift in training procedure between acquisition and reversal increased the number of subjects who reached criterion immediately after perseveration. Since these results are difficult to explain in terms of traditional learning theories, an alternative response-switching strategy explanation was proposed.     

TREATMENT OF MULTIPLY CONTROLLED PROBLEM BEHAVIOR

The aggressive behavior of a young boy with developmental delays occurred most frequently following a request to pick up his toys. The request ended a period of play and social interaction. This suggested the presence of multiple establishing operations. The initial treatment consisted of praise, a break, and access to the toys contingent on compliance. Results showed that aggression decreased only when we added social interaction to the break. Findings are discussed regarding treating multiply controlled problem behavior without extinction.
