We used repetition blindness to investigate the nature of the representations underlying identification of manipulable objects. Observers named objects presented in rapid serial visual presentation streams containing either manipulable or nonmanipulable objects. In half the streams, 1 object was repeated. Overall accuracy was lower when streams contained 2 different manipulable objects than when they contained only nonmanipulable objects or a single manipulable object. In addition, nonmanipulable objects induced repetition blindness, whereas manipulable objects were associated with a repetition advantage. These findings suggest that motor information plays a direct role in object identification. Manipulable objects are vulnerable to interference from other objects associated with conflicting motor programs, but they show better individuation of repeated objects associated with the same action.

The focus of this study was to identify factors that differentiate women drug abusers who had experienced suicidal ideation from those who did not. Face-to-face interviews were conducted with 221 cocaine-using women in Atlanta, GA, 88 (39.8%) of whom reported thinking about committing suicide at least once during the 90 days prior to interview and 133 (60.2%) of whom did not. Multivariate logistic regression was used to identify predictors of suicidal ideation, and post hoc goodness-of-fit tests were conducted to assess the robustness of final models derived. Model 1 excluded all psychosocial functioning measures and Model 2 included these items. Both models showed that suicidal ideation was more common among women who were unemployed, had been abused sexually, engaged in sexual relations to cope with stresses, or had less helpful relatives. In addition, Model 1 revealed a heightened risk for women experiencing financial problems and those who had a previous mental health diagnosis, whereas Model 2 showed an elevated risk among women who experienced anxiety and those who had lower levels of self-esteem. These findings suggest the need for prevention and intervention programs that target at-risk women, and for such programs to include an emphasis on suicidal ideation in addition to focusing on risk factors that are addressed more commonly. 相似文献

Theory and research dealing with self-regulation have focused primarily on instances of self-regulation that involve high levels of self-reflection and effortful self-control. However, intentionally trying to control one's behavior sometimes reduces the likelihood of achieving one's goals. This article examines the process of hypo-egoic self-regulation in which people relinquish deliberate, conscious control over their own behavior so that they will respond more naturally, spontaneously, or automatically. An examination of spontaneously occurring hypo-egoic states (such as flow, deindividuation, and transcendence) suggests that hypo-egoic states are characterized by lowered self-awareness and/or an increase in concrete and present-focused self-thoughts. In light of this, people may intentionally foster hypo-egoism via two pathways-(a) taking steps to reduce the proportion of time that they are self-aware (such as repeating a behavior until it is automatic or practicing meditation) or (b) increasing the concreteness of their self-thoughts (such as inducing a concrete mindset or practicing mindfulness). In this way, people may deliberately choose to regulate hypo-egoically when effortful control might be detrimental to their performance. 相似文献

Differential reinforcement of alternative behavior (DRA) is used frequently as a treatment for problem behavior. Previous studies on treatment integrity failures during DRA suggest that the intervention is robust, but research has not yet investigated the effects of different types of integrity failures. We examined the effects of two types of integrity failures on DRA, starting with a human operant procedure and extending the results to children with disabilities in a school setting. Human operant results (Experiment 1) showed that conditions involving reinforcement for problem behavior were more detrimental than failing to reinforce appropriate behavior alone, and that condition order affected the results. Experiments 2 and 3 replicated the effects of combined errors and sequence effects during actual treatment implementation. 相似文献

First graders' literacy and self-regulation gains: The effect of individualizing student instruction
Carol McDonald Connor Claire Cameron Ponitz Q. Monét Travis Frederick J. Morrison 《Journal of School Psychology》2010,48(5):433-455
We examined the effect of individualizing student instruction (ISI; N = 445 students, 46 classrooms) on first graders' self-regulation gains compared to a business-as-usual control group. Self-regulation, conceptualized as a constellation of executive skills, was positively associated with academic development. We hypothesized that the ISI intervention's emphasis on teacher planning and organization, classroom management, and the opportunity for students to work independently and in small groups would promote students' self-regulation. We found no main effect of ISI on self-regulation gains. However, for students with weaker initial self-regulation, ISI was associated with greater self-regulation gains compared to peers in control classrooms. The ISI effect on self-regulation was greater when the intervention was more fully implemented. 相似文献

The theory of direct perception holds that perception is specific to properties of ambient energy arrays. This article explores a similar approach to perceptual and perceptual-motor learning: Change due to learning is portrayed as specific to properties of ambient energy arrays. This type of learning is labeled direct learning. It is argued that a theory of direct learning explains a wide range of phenomena in ecologically relevant and informationally rich situations as well as in simpler experimental situations. Previous experimental results are reanalyzed and reinterpreted from the perspective of direct learning. To achieve this, the notion of information space is introduced. In information spaces, points represent ambient energy variables, paths represent change due to learning, and vector fields represent information that guides learning. These concepts also allow the theory of direct learning to be connected to and to take advantage of the theory of ordinary differential equations. 相似文献

The purpose of this article is to describe Fortalezas Familiares (FF; Family Strengths), a community‐based prevention program designed to address relational family processes and promote well‐being among Latino families when a mother has depression. Although depression in Latina women is becoming increasingly recognized, risk and protective mechanisms associated with children's outcomes when a mother has depression are not well understood for Latino families. We begin by reviewing the literature on risk and protective psychosocial mechanisms by which maternal depression may affect Latino youth, using family systems theory and a developmental psychopathology framework with an emphasis on sociocultural factors shaping family processes. Next, we describe the theoretical basis and development of the FF program, a community‐based 12‐week intervention for Latina immigrant women with depression, other caregivers, and their children. Throughout this article, we use a case study to illustrate a Latina mother's vulnerability to depression and the family's response to the FF program. Recommendations for future research and practice include consideration of sociocultural processes in shaping both outcomes of Latino families and their response to interventions. 相似文献
