OBJECTIVE: It has been suggested that survivors of ongoing childhood sexual abuse (CSA) tend to have been reared in ineffective family environments that render them particularly vulnerable to maltreatment and which foster psychological difficulties beyond those accounted for solely by their abuse. If this conjecture is valid, one would expect that the family of origin environments of CSA survivors would be disturbed whether their abuser was intra-familial or extra-familial. To assess this hypothesis, two studies compared the childhood family of origin environments and supportive parenting characteristics of a clinical sample of women sexually abused by family members only (the intra-familial group), by non-family members only (the extra-familial group), and by both family and non-family members (the "both" group). METHOD: Study 1 compared the three groups (total N = 213) using the Family Environment Scale (FES). Study 2 compared groups (total N = 86) on the positive parenting scales of the Exposure to Abusive and Supportive Environments Parenting Inventory (EASE-PI). RESULTS: In Study 1, multivariate analyses indicated significant differences on the independence, cohesion, and conflict subscales of the FES. Pairwise comparisons revealed that the extra-familial group reported significantly higher levels of family independence and lower levels of conflict than the other two groups. In addition, the extra-familial group reported higher levels of cohesion than the intra-familial group. However, the effect sizes of these comparisons were extremely small. In Study 2, multivariate analyses revealed no group differences on the EASE-PI scales. CONCLUSIONS: Low effect sizes on the three significant FES scales, non-significance on the remaining seven FES scales, and non-significance on the EASE-PI scales suggest that there is considerable similarity in the family of origin environments of adult female CSA survivors seeking therapy regardless of whether their perpetrators were family members, non-family members, or both family and non-family members. 相似文献

In Experiment 1, four groups of rats were initially trained on a discrimination which established a stimulus as a signal for reinforcement. That signal was then presented during subsequent partial reinforcement training in a way that could potentially interfere with retrieval of the memory of nonreinforcement (SN) on the preceding trial either because (1) thestorage and retrieval contexts for SN were different (retrieval failure hypothesis), or (2) the memory of reinforcement produced by the signal acted as a competing memory (competing memory hypothesis). Experiment 1 supported the competing memory hypothesis. In Experiment 2, we investigated the effect of stimulus change on the capacity of the context to retrieve a competing memory of a temporally remote reinforcement event with which the context was strongly associated. Retrieval of a competing memory was impaired by differences between the storage and retrieval contexts in a manner analogous to the effect of context on retrieval of a reinforcement event memory from an immediately preceding trial. 相似文献

These experiments demonstrate improvement in reading score as a result of computer-generated syntactically formated text. In all experiments, the subjects took a subset of the Chapman-Cook speed of reading test. In experiment 1, the space size between words reflected the major phrase structure boundaries. In experiment 2, the spacing corresponded to both the major and minor phrase structure boundaries. Experiment 1 indicates that poor readers are aided by syntactically formated text. Experiment 2 indicates that a more finely detailed formating also helps poor readers. The use of a microcomputer to prepare the material will make it practical to improve the readability of large amounts of text. 相似文献

In an attempt to demonstrate the effectiveness of instructional programming in counseling, an experimental evaluation of a ten-week program aimed at teaching skills and strategies of self-instruction to high school students was conducted. Thirty-two grade ten students were assigned randomly to an experimental self-instruction group and a control group. Dependent variables included Rotter's (1966) Control of Reinforcement Questionnaire, Rosenbaum's (1980) Self-control Schedule, a curriculum-specific test of self-instruction concepts, and a transfer test. Results revealed that students in the experimental, self-instruction program outperformed students in the control group on all dependent variables except for the Self-control Schedule. Content analysis of student responses to the transfer test showed a distinct pattern of skill development in the experimental group from pretest to posttest. Implications for the development and offering of instructional counseling programs are drawn.Many students of counseling have argued that counseling is essentially a kind of teaching (Carkhuff and Berenson, 1976; Ellis, 1977; Katz and Ivey, 1977; Krumboltz and Thoresen, 1976; Sorenson, 1967). More recently, Martin and his colleagues have developed an approach to counseling that employs models of instruction as a basis for the development and implementation of a broad range of counseling interventions and programs (Hiebert et al., 1981; Martin and Hiebert, 1982; Martin et al., 1981; Martin et al., 1980). Martin (1983) also has suggested that counselors in schools and elsewhere can make use of systematic teaching programs to help clients/students acquire functional skills in a variety of areas such as anxiety management, decision making, interpersonal skills, and so forth. In the development and offering of such programs, counselors act as curriculum developers and instructors. Initial evidence for the viability of this type of instructional counseling in schools was provided by Haynes et al. (1983), and Leal, Baxter, Martin, and Marx (1981) who developed programs based on cognitive and behavioral counseling methods that were successful in alleviating the test anxieties experienced by high school students. The experiment reported here extends the work of Martin and others in instructional counseling by evaluating an instructional program designed to teach a series of integrated skills of self-instruction to high school students. [Note that the term self-instruction is used here to refer to the activities of people engaged in systematic self-change, and is not intended to connote the system of self-instruction training developed by Donald Meichenbaum (1977).]Nearly all teachers and curriculum specialists share at least one goal: to help students acquire the capacity to engage in self-directed learning. Most often, it is assumed that school students will acquire skills in areas such as self-instruction and critical thinking (skills often seen as necessary requisites to self-directed learning) as a result of stimulating interactions with traditional school curricula. A frequently voiced alternative is to attempt to teach such skills directly (cf. Beyers, 1984a, 1984b), more or less as a curriculum in their own right. Many attempts have been made to do this, but few have received detailed empirical, experimental analysis. In a recent meta-analysis of primary prevention studies conducted in schools, Baker, Swisher, Nadenichek, and Popowicz (1984) found 40 such studies that had been conducted since 1970. Most of the experimental programs in the studies reviewed were targeted at improving students' communication skills, decision making and problem solving skills, and self-awareness. None of the studies reviewed by Baker et al. included instructional interventions that attempted to teach a broad range of skills and strategies that would permit students to plan, implement, and evaluate programs of personal change and development. Teaching school pupils to engage in systematic self-instruction for purposes of personal change simply has not been attempted, to date, in the context of an experimentally controlled investigation. Given an increasing number of pleas for exactly this kind of broad-based school programming (Martin, 1983; Sprinthall, 1984), the need for controlled experimental studies in this area is acute.Self-introduction or learning to learn has been the subject of considerable theorizing by both cognitive and instructional psychologists (Gagné, 1977; Bransford, 1979). Experimental work by Ann Brown and her colleagues (Brown, 1978; Brown et al., 1979) has highlighted the difficulty of teaching various metacognitive strategies that would seem basic to the capacity to self-instruct so as to ensure the transfer of such strategies to tasks other than those employed during strategy acquisition. At the same time, Brown's research also shows that the teaching of generalizable metacognitive strategies such as self-testing is possible, even with educable retarded children (Brown, et al., 1979). Other research concerned with differences between expert and novice knowledge has highlighted the importance of the ability to access declarative knowledge stores and the availability of relevant procedural knowledge in attempting to explain these differences (Chi et al., 1982; Leinhardt, 1983). [See Anderson, (1980) for formal definitions and discussions of declarative and procedural knowledge.] The greater ability of experts to function as independent learners or self-instructors in their areas of expertise likely is related to such differences. While it sometimes is unclear as to whether self-instructional competence resides in procedural knowledge stores or cognitive and/or metacognitive strategies, it seems clear that learning to learn involves more than simply acquiring necessary declarative knowledge in relevant substantive areas (Glaser, 1984). Thus, explicit, direct instruction in skills and strategies of self-instruction probably is necessary if students in schools are to learn to direct their own learning and development.The experiment reported here was conducted to supply initial experimental data about the possible effectiveness of a program designed to teach skills and strategies of self-instruction to high school students. It is a study of a ten-week instructional counseling program developed to teach self-instruction skills in areas such as decision making, gathering information, self-assessment, framing objectives, planning, and self-evaluation. As such, it is a more comprehensive program than other programs of primary prevention in schools that have been studied experimentally. While a variety of school and extracurricular situations were employed as illustrative contexts for presenting information about these skills to the students, the goal of the experimental program was to teach the self-instruction skills as detached skills that could be applied to a variety of situations and life circumstances. This approach was viewed as contrasting with traditional approaches in which such skills are thought to be acquired indirectly as a result of working through a series of tasks in defined substantive areas such as mathematics, history, or physics. In this latter method, it is likely that such skills, if they are acquired, become embedded in specific substantive contexts and are therefore less likely to generalize to situations or contexts other than those in which they were acquired (see Rigney, 1978 for the distinction between detached and embedded strategies). Dependent variables employed in the study were selected to test for the acquisition and transfer of targeted skills as well as for the acquisition of underlying beliefs about one's ability to control or influence external and internal events. The latter type of learning is thought by many counselors to be of great importance, particularly if attitudes and beliefs are learned that affect clients' attributional styles and/or tendencies (Strong and Claiborn, 1982).The overall purpose of the experiment was to determine whether instructional counseling curricula could be developed that would succeed in teaching detached strategies/skills of self-instruction to high school students. Should such instruction be possible, additional support would be provided for the notions of instructional counseling and counselors as curriculum developers and instructors. After all, a major part of counseling typically is associated with assisting clients to make decisions, gather information, frame goals and objectives, assess their situations and capabilities, plan actions, and evaluate the effects of their actions—all components of the self-instruction program taught to the experimental students in this study.The specific hypotheses investigated were that participation in the experimental instructional counseling program would increase: 1) students' knowledge of self-instruction skills (acquisition learning), 2) students' abilities to apply this knowledge to everyday events (transfer learning), and 3) students' attitudes consistent with higher levels of self-control and internal attributional processes (general attitudinal learning).The research reported here was supported by a grant from the Chairpersons' Research Fund, Simon Fraser University.The authors gratefully acknowledge the assistance of Bruce Dallin, Louise Bourassa, Olwyn Irving, David Langton and the Abbotsford School District (British Columbia, Canada) in completing this work. 相似文献

Two recent articles in this journal – one by Morris, the other by Pfleegor & Rosenberg – have revived the philosophical discussion of the ethics of deception in sport which had largely laid dormant since the 1973 publication of Pearson’s ‘Deception, Sportsmanship, and Ethics’. Morris and Pfleegor & Rosenberg both share with Pearson the view that ethical deceptive sport acts are those that relate to sport-specific skills. However, whereas Pearson ultimately grounds this view in the agreement she takes to obtain amongst sport participants, both recent treatments overlook this fundamental aspect of her account and offer alternative justifications for that view. I argue, though, that in both cases the arguments offered are incomplete precisely because they require an appeal to the agreement amongst participants that lies at the foundation of Pearson’s account. On all three treatments, I argue, what ultimately determines an action’s ethical status is not its relation to sport-specific skills, but its conformity to, or violation of, that agreement. I conclude with a discussion of what this implies for future work on deception in sport. 相似文献

Piaget's structural theory of formal thought suggests that a general construct of formal reasoning exists. The content of the task and type of problem employed are often ignored in Piagetian based studies but are important for generalizing findings to other studies and to educational problems. The study reported here examines content and problem effects of formal thought in 13-year-old adolescents. Specifically, three controlling variables tasks with different content and two question type tests (analysis and controlling questions) were administered to 120 seventh graders. Ability measures and personality dimensions associated with formal reasoning in the literature are used to clarify what formal reasoning is and how content and problem type are involved in formal reasoning. Significant main effects were found for problem and content effects (p = 0.001), and a significant interaction was found between the two (p = 0.001). Across the three tasks general ability, field dependency, and locus of control were consistently and significantly related to the controlling questions. However, only measures of field dependency were related to the analysis questions. Combinations of ability and personality factors were found to be uniquely related to each task, within each question type. Results have implications for a theory of formal thought and the teaching of the controlling variables strategy. 相似文献

AbstractThe National Institute for Environmental Health Sciences has called for targeted efforts to engage underserved youth in environmental education programs that support environmental literacy and contribute to the development of a diverse workforce pipeline for environmental science-related occupations. Evidence suggests that career knowledge among low income and minority youth is more likely to be incompatible with post-secondary educational opportunities than other racial and ethnic groups. One approach to attenuating discordant college and career expectations among underserved youth is building networks for information sharing between secondary and post-secondary students. The purpose of this commentary is to describe the development and implementation of a high school curriculum on environmental science and environmental justice by Texas A&M University in collaboration with community engagement partners, students, and teachers at Furr High School, an innovative XQ Super School in Houston, Texas. 相似文献

In two conditioned lick suppression experiments with rats, we examined the permanence of the overshadowing effect as a function of the number of compound reinforced training trials. In Experiment 1, robust overshadowing was observed following 4 compound-US pairings but dissipated with 36 pairings. Overshadowing decreased because responding to the overshadowed stimulus increased, not because responding by the control group decreased. This dissipation was stimulus specific and not attributable to a response ceiling. Experiment 2 extended the generality of the effect to a sensory preconditioning design and further demonstrated that overshadowing lost through many compound-US pairings was restored by posttraining extinction of the training context. The results are explicable in terms of the extended comparator hypothesis (Denniston, Savastano, & Miller, 2001) under the assumption that the impacts of first- and second-order comparator processes grow differentially as a function of number of trials. 相似文献

Four experiments assessed visual short-term memory capacity in 4- to 13-month-old infants by comparing their looking to changing and nonchanging stimulus streams presented side by side. In each stream, 1 to 6 colored squares repeatedly appeared and disappeared. In changing streams, the color of a different randomly chosen square changed each time the display reappeared; the colors remained the same in nonchanging streams. Infants should look longer at changing streams, but only if they can remember the colors of the squares. The youngest infants preferred changing streams only when the displays contained one object, whereas older infants preferred changing streams when the displays contained up to 4 objects. Thus, visual short-term memory capacity increases significantly across the first year of life. 相似文献

The purpose of this study was to evaluate a computer-based strategy for personalizing verbal problems used in mathematics
instruction. Personalization was achieved through a computer program that incorporated names of familiar people and events,
such as the student’s friends and birth date, into print copies of lesson examples. In two control treatments, concrete (nonadaptive)
contexts and abstract contexts were employed. Subjects were 54 fifth- and sixthgraders studying a lesson on division of fractions.
Results showed the personalized-context treatment to be advantageous relative to one or both control treatments for (a) solving
conventional word problems, (b) solving transfer problems, (c) recognizing rule procedures, and (d) developing favorable attitudes
toward materials. Theoretical interpretations of these effects are discussed, along with considerations about the practicality
and effectiveness of the present application using print materials compared to an earlier one using CAl. 相似文献
