This study examined the treatment utility of brief experimental analysis for selecting skill-based oral reading interventions that targeted acquisition and fluency. Two second and one third grade student served as participants. The potentially most and least effective instructional packages identified from the brief experimental analysis for each student were alternated during an extended analysis phase. The instructional components that were compared were based on an ease of implementation hierarchy, with the brief experimental analysis used to select the hypothesized most effective instructional package for oral reading. Visual analysis of extended analysis data revealed that the hypothesized most effective combination of instructional components identified from the brief analysis produced greater initial gains in reading for two children (i.e., over 29 and 21 intervention days) and greater gains in reading throughout the extended analysis phase for the third child. Thus, the investigation provided preliminary evidence for the treatment utility of using brief experimental analysis to select effective and efficient oral reading instructional interventions. Implications, limitations, and future research topics are discussed. 相似文献

Source monitoring involves judgments regarding the origin of information (M. K. Johnson, S. Hashtroudi, & D. S. Lindsay, 1993). When participants cannot remember the source in a source-monitoring task, they may guess according to their prior schematic knowledge (U. J. Bayen, G. V. Nakamura, S. E. Dupuis, & C.-L. Yang, 2000). The present study aimed at specifying conditions under which schematic knowledge is used in source monitoring. The authors examined the time course of schema-based guesses with a response-signal technique (A. V. Reed, 1973), and multinomial models that separate memory and guessing bias. Use of schematic knowledge was observed only when asymptotic old-new recognition was low. The time course of schematic-knowledge retrieval followed an exponential growth function. Implications for theories of source monitoring are discussed. 相似文献

Probabilistic reward has been shown to affect children's choice behavior in game-like activities. We examined the effects of a lottery system containing progressively lower exchange ratios on children's completion of math problems. Two of the 3 children completed problems above baseline levels until the chance of exchange dropped to 25%. This study describes a potentially useful method for examining reinforcement schedules in applied settings and extends previous research on probabilities of reinforcement. 相似文献

This study examined the psychometric properties of the Drinking Motives Measure (DMM) on a sample of 227 collegiate athletes. Confirmatory factor analyses indicated that the 4-factor structure of the DMM provided a better fit than either 2- or 1-factor models, but the overall fit of the 4-factor model was moderate at best. A revised 3-factor model consistent with prior research (M. L. Cooper, M. Russell, J. B. Skinner, & M. Windle, 1992) provided the best fit. Hierarchical multiple regression analyses indicated that the 3 DMM factors included in the revised model accounted for 17%-21% of the unique variance on alcohol consumption variables. Results provide preliminary evidence supporting the internal consistency, construct validity, and convergent validity of the revised 3-factor DMM with collegiate athletes. 相似文献

This study investigated the connection between wisdom as a body of expert knowledge about the meaning and conduct of life and indicators of affective, motivational, and interpersonal functioning. Structural equation analyses showed that individuals higher on wisdom-related knowledge reported (a) higher affective involvement combined with lower negative and pleasant feelings, (b) a value orientation that focused conjointly on other-enhancing values and personal growth combined with a lesser tendency toward values revolving around a pleasurable life, and (c) a preference for cooperative conflict management strategies combined with a lower tendency to adopt submissive, avoidant, or dominant strategies. These findings corroborate the theoretical notion that wisdom involves affective modulation and complexity rather than the predominant seeking of pleasure and also a joint motivational commitment to developing the potential of oneself and that of others. 相似文献

A large body of research has shown that when people are reminded of their mortality, their defense of their cultural worldview intensifies. Although some psychological defenses seem to be instigated by negative affective responses to threat, mortality salience does not appear to arouse such affect. Terror management theory posits that the potential to experience anxiety, rather than the actual experience of anxiety, underlies these effects of mortality salience. If this is correct, then mortality-salience effects should be reduced when participants believe they are not capable of reacting to the reminder of mortality with anxiety. In a test of this hypothesis, participants consumed a placebo purported to either block anxiety or enhance memory. Then we manipulated mortality salience, and participants evaluated pro- and anti-American essays as a measure of worldview defense. Although mortality salience intensified worldview defense in the memory-enhancer condition, this effect was completely eliminated in the anxiety-blocker condition. The results suggest that some psychological defenses serve to avert the experience of anxiety rather than to ameliorate actually experienced anxiety. 相似文献

This study investigated students' allocation of responding as a function of task difficulty and type of reinforcement contingency (i.e., accuracy based or time based). Four regular education fourth-grade students were presented with two identical stacks of easy and then difficult math worksheets using a reversal design. Regardless of condition, completing problems from each stack of worksheets was reinforced according to a different contingency; one required correct completion of math problems (accuracy based) and one required on-task behavior (time based). Results suggested that 3 of the 4 students preferred the accuracy-based contingency when given easy material and the time-based contingency when given difficult material. One student allocated more responding to the accuracy-based contingency when given easy problems but did not show a clear preference for either contingency with difficult problems. The implications of these findings for designing reinforcement-based programs for tasks of varying difficulty are discussed. 相似文献

In order to determine the extent to which depression complicates Huntington's disease (HD), we have analyzed the existing literature on depression in HD in order to report the prevalence, clinical manifestations, and treatment of HD depression. By means of MEDLINE literature searches and reviews of HD articles' bibliographies, we identified for our analysis 16 HD depression studies. Our results indicate that the prevalence of depression is 30% for all HD patients. Clinical manifestations of HD depression include a marked increased risk for suicide. The etiology of HD depression is unclear, but may be due to a number of factors, such as dysfunction in the caudate nucleus, dysfunction in the ventral striatum, and various genetic factors that are discussed in this review. Case reports and case series support the efficacy of standard antidepressant interventions in resolving symptoms of depression. Efficacious treatments reported in the literature include tricyclic antidepressants, monoamine oxidase inhibitors, selective serotonin reuptake inhibitors, and electroconvulsive therapy. In this study, the successful anecdotal treatment of seven consecutive HD depressed patients with sertraline suggests that sertraline may be a safe and efficacious treatment of HD depression. 相似文献

This study replicated previous basic research into the dynamics of choice and extended this analysis to children's behavior in a naturalistic setting. Two preschoolers with disabilities were observed interacting with their teachers at baseline and during an experimental analysis involving four pairs of concurrent variable‐interval schedules of adult attention implemented by an experimenter. Each child was exposed to four experimental phases in which the relative reinforcer rates for on‐ and off‐task behavior were 10:1, 1:1, 1:10, and reversed back to 10:1. The 10:1 phase was designed to mimic the same schedules and types of adult attention observed at baseline. We used the generalized matching equation to model steady‐state behavior at the end of the transition phases and to evaluate changes in sensitivity at various points throughout the phases. Choice in transition was evaluated by plotting log behavior ratios by session, cumulated time on‐ and off‐task and cumulated attention for on‐ and off‐task behavior by session, and interreinforcer behavior ratios following different sequences of the first four reinforcer deliveries. The generalized matching equation accounted for a large proportion of variance in steady‐state responding, sensitivity values increased steadily throughout the phases, patterns of choice in transition were similar to those reported in basic research, and interreinforcer preference generally shifted toward the just‐reinforced alternative. These findings are consistent with previous basic research and support the generality of the dynamics of choice to children's on‐ and off‐task behavior reinforced by adult attention. 相似文献

Killing appears to perpetuate itself even in the absence of retaliation. This phenomenon may occur in part as a means to justify prior killing and so ease the threat of prior killing. In addition, this effect should arise particularly when a killer perceives similarity to the victims because similarity should exacerbate threat from killing. To examine these ideas, the authors developed a bug-killing paradigm in which they manipulated the degree of initial bug killing in a "practice task" to observe the effects on subsequent self-paced killing during a timed "extermination task." In Studies 1 and 2, for participants reporting some similarity to bugs, inducing greater initial killing led to more subsequent self-paced killing. In Study 3, after greater initial killing, more subsequent self-paced killing led to more favorable affective change. Implications for understanding lethal human violence are discussed. 相似文献
