Symbolic play and its cognitive significance.

Explored the relationship between symbolic play training and conservation attainment. Ss were 30 middle-class nonconserving children, with a median age of 4.3 yrs. After extensive pretests on conservation of quantity, 15 nonconservers were assigned to the experimental condition, consisting of 3 sessions of symbolic play on consecutive days, and 15 Ss were assigned to the control condition, consisting of 3 daily play sessions with puzzles, mosaics, and drawing tasks. Subsequent to the play sessions, Ss were given conservation of quantity posttests. Results show that 13 of the experimental Ss manifested some change in solving conservation problems, with 4 Ss reaching the level of full conservation attainment. Only a single S from the control group showed a change toward conservation on the posttests. Data are interpreted as supporting a cognitive function of symbolic play.

A longitudinal analysis of logical reasoning relationships: Conservation and transitive inference.

102 children originally assessed in 1973 were retested 1 yr later on a series of conservation and transitive inference tasks (length and weight content areas). An additional sample of matched cohort/grade Ss (1st- and 4th-grade levels) were assessed in the 2nd yr only to permit evaluation of repeated measurement biases for the longitudinal sample. Results indicate that there were no effects of presentation order, selective survival, repeated measurement, sex, or content area; these variables did not interact with each other. Analyses of the longitudinal Ss' conservation task performances over the annual interval indicated significant grade-level distinctions, Yr 1 vs Yr 2 differences, and type of conservation distinctions (identity vs equivalence). Identity conservation scores were consistently superior to equivalence conservation scores, a superiority most notable for the youngest Ss. Transitive inference tasks were significantly less difficult than equivalence conservation tasks. Most importantly, evidence for a developmental mastery sequence (transitivity-conservation) was demonstrated. Identity-equivalence conservation task distinctions were most apparent for the without verbal justification response criterion.

Necessity in conservation and nonconservation.

Conducted a study with 57 Ss (mean age, 6.78 yrs) to assess their conservation and transitivity of number, length, liquid amount, and weight. The conservation deduction argues that given A = B, B is transformed to B-sup-1, and that Ss somehow know that B-sup-1 = B as well as the concept of transitivity of equality Ss; thus should conclude that A must also equal B-sup-1, which is the conservation deduction. Results show that most Ss gave correct transitivity judgments, but only half gave correct justifications. In contrast, all the conservers gave good reasons. Overall conservation and transitivity correlated, and conservers were more likely to give good transitivity reasons than nonconservers. Nearly all conservers and about half the nonconservers saw their conservation judgments as necessary; thus, the relationships between conservation and necessity for number, length, amount, and weight were significant.

Liquid conservation in orangutans (Pongo pygmaeus) and humans (Homo sapiens): Individual differences and perceptual strategies.

Four orangutans (1 juvenile, 2 subadults, and 1 adult) and 10 6–8-yr-old children were tested in 4 liquid conservation tasks of increasing levels of difficulty. Task difficulty depended on the type of transformation (continuous vs discontinuous quantities) and the relative contrast between the shapes of the containers. Results indicate that orangutans did not display conservation in the strict sense; instead they showed "partial" conservation (intermediate reactions according to J. Piaget & B. Inhelder, 1941). In contrast, some of the children provided evidence of conservation in all 4 tasks, showing "true" or logically necessary conservation in the original sense proposed by J. Piaget and B. Inhelder (1941). Although orangutans did not show conservation in the strict sense, as J. Piaget (1955) and others have generally agreed it should be defined, orangutans behaved as individual and creative problem solvers, adopting different perceptual strategies depending on the task.

Breast conservation therapy after augmentation mammaplasty: is it appropriate?

Breast conservation therapy, consisting of lumpectomy, axillary node dissection, whole-breast irradiation, and a boost to the tumor bed, is an increasingly popular option for the treatment of breast cancer. Among patients with stage I and stage II disease, breast conservation therapy yields survival rates equivalent to those for mastectomy. The cosmetic results of radiotherapy are usually good, and this approach preserves an intact, sensate breast. Most studies on breast conservation therapy, however, have been performed in nonaugmented patients. Relatively little has been published regarding breast conservation therapy in the presence of silicone implants. Between 1981 and 1994, we treated 33 augmented patients with breast conservation therapy. Among 26 individuals for whom complete follow-up data were available, 17 (65 percent) developed significant capsular contracture on the irradiated side. Thus far 8 patients with radiation-induced contracture have undergone corrective surgery. In our experience, augmented breast cancer patients treated with breast conservation therapy have less satisfactory cosmetic results than nonaugmented women. In addition, mammographic follow-up, critical for identifying local recurrence, may be impaired by the presence of an implant and capsular contracture. On the basis of these considerations, breast conservation therapy may be less than optimal in augmented cancer patients unless explantation is performed before treatment.

Behavioral interventions in resource conservation: A systems approach based on behavioral economics.

Outlines some of the advantages of an integration of psychological (social-learning) and economic conceptualizations when developing behavioral interventions in resource conservation. The procedures and results of rebate studies in residential energy and water conservation are presented in which rebates were used as a method to modify conservation behaviors and to estimate experimental price elasticity in contrast to the usual econometric methods. A meta-analysis is performed on behavioral energy studies conducted from 1973 to 1980, which shows that the effectiveness of rebates and feedback is partially explained by an economic factor. Also reviewed are field-based studies designed to modify perceptions of comfort and residential energy conservation in addition to the development of a rebate system instituted to reduce domestic water consumption. Maximization theory is offered as an integrative, conceptual framework that may be useful for planning resource conservation interventions.
