Phonological processing skills and the Reading Recovery Program. 总被引:1,自引:0,他引:1
Sought to determine whether the Reading Recovery Program would be more effective if systematic instruction in phonological recoding skills were incorporated into the program. First-grade at-risk readers were divided into 3 matched groups of 32 children each; a modified Reading Recovery group, a standard Reading Recovery group, and a standard intervention group. The children in the modified Reading Recovery group received explicit code instruction involving phonograms. Results indicated that, although both Reading Recovery groups achieved levels of reading performance required for discontinuation of the program, the modified Reading Recovery group reached these levels of performance much more quickly. Results further indicated that the children selected for Reading Recovery were particularly deficient in phonological processing skills and that their progress in the program was strongly related to the development of these skills.

Autoshaped key pecking in pigeons was eliminated by presenting reinforcers only during non-CS periods (negatively contingent reinforcement) or in both non-CS and CS periods (noncontingent reinforcement). In either case, when all reinforcers were subsequently removed (simple extinction), responding recovered strongly (Experiment 1). Recovery in extinction occurred only if the CS was in a conditioned state when non-CS reinforcers were introduced (Experiment 2). Recovery from noncontingent reinforcement was virtually complete, since total responding in extinction after response elimination was not less than in control groups extinguished without an intervening response-elimination phase (Experiment 3). Recovery also occurred for nonautoshapable, instrumentally reinforced key pecking (Experiment 4). The hypothesis that recovery is due to reinstatement of the non-CS stimulus conditions of acquisition (absence of food) was not supported (Experiments 5 and 6). Other accounts of recovery are considered. 相似文献

预应变对Ni50.2Ti49.8合金记忆特性的影响 总被引:1,自引:0,他引:1
研究了Ni50.2Ti49.8合金在5种不同预应变(1.96%,3.96%,5.88%,7.85%,9.96%)下的回复应变和逆相变温度;恒定预应变5.88%下,热机械循环对回复应变和逆相变温度的影响。结果表明:预应变使得逆相变温度升高,预应变越大逆相变温度越高。随着预应变的增加回复应变增加,预应变增加到一定程度时回复应变达到最大值,随后回复应变随预应变增加而减少。恒定预应变下热机械循环,随循环次数增加,逆相变温度下降,回复应变减少,随着循环次数进一步增加,逆相变温度和回复应变逐步达到稳定值。 相似文献

Conducted 5 experiments with female CF1 mice sustaining sham-operations, simultaneous, or successive bilateral frontal pole transections. Recovery of a passive-avoidance deficit occurred following both simultaneous and successive transsections. Recovery was a function of time either following the simultaneous procedure or between the 2 stages of the successive procedure. Recovered simultaneous Ss were hyposensitive to impairment of passive-avoidance learning by d-amphetamine, whereas recovered successive Ss were not. Alpha-methyltyrosine facilitated recovery following either simultaneous or successive brain damage. Results are consistent with a denervation supersensitivity model of recovery of function.
