We used delayed multiple-baseline and multiple-probe techniques to assess the effects of self-evaluation training on the legibility of cursive handwriting. Five secondary special education students with difficult-to-read handwriting served as participants. All participants improved the legibility of their handwriting during self-evaluation training. A systematic withdrawal of the training package demonstrated maintenance of treatment effects. For the most part, the students' handwriting remained at least 90% legible to judges following the systematic withdrawal of the self-evaluation training.  相似文献

The interaction between attentional capacity, motor control processes, and strategic adaptations to changing task demands was investigated in handwriting, a continuous (rather than discrete) skilled performance. Twenty-four subjects completed 12 two-minute handwriting samples under instructions stressing speeded handwriting, normal handwriting, or highly legible handwriting. For half of the writing samples, a concurrent auditory monitoring task was imposed. Subjects copied either familiar (English) or unfamiliar (Latin) passages. Writing speed, legibility ratings, errors in writing and in the secondary auditory task, and a derived measure of the average number of characters held in short-term memory during each sample ("planning unit size") were the dependent variables. The results indicated that the ability to adapt to instructions stressing speed or legibility was substantially constrained by the concurrent listening task and by text familiarity. Interactions between instructions, task concurrence, and text familiarity in the legibility ratings, combined with further analyses of planning unit size, indicated that information throughput from temporary storage mechanisms to motor processes mediated the loss of flexibility effect. Overall, the results suggest that strategic adaptations of a skilled performance to changing task circumstances are sensitive to concurrent attentional demands and that departures from "normal" or "modal" performance require attention.  相似文献

Letter production through handwriting creates visual experiences that may be important for the development of visual letter perception. We sought to better understand the neural responses to different visual percepts created during handwriting at different levels of experience. Three groups of participants, younger children, older children, and adults, ranging in age from 4.5 to 22 years old, were presented with dynamic and static presentations of their own handwritten letters, static presentations of an age‐matched control's handwritten letters, and typeface letters during fMRI. First, data from each group were analyzed through a series of contrasts designed to highlight neural systems that were most sensitive to each visual experience in each age group. We found that younger children recruited ventral‐temporal cortex during perception and this response was associated with the variability present in handwritten forms. Older children and adults also recruited ventral‐temporal cortex; this response, however, was significant for typed letter forms but not variability. The adult response to typed letters was more distributed than in the children, including ventral‐temporal, parietal, and frontal motor cortices. The adult response was also significant for one's own handwritten letters in left parietal cortex. Second, we compared responses among age groups. Compared to older children, younger children demonstrated a greater fusiform response associated with handwritten form variability. When compared to adults, younger children demonstrated a greater response to this variability in left parietal cortex. Our results suggest that the visual perception of the variability present in handwritten forms that occurs during handwriting may contribute to developmental changes in the neural systems that support letter perception.  相似文献

This research broadens our understanding of racial and gender bias in leader evaluations by merging implicit leadership theory and social dominance perspectives. Across two experimental studies (291 participants), we tested the prediction that bias in leader evaluations stemming from White and masculine leader standards depends on the extent to which people favor hierarchical group relationships (social dominance orientation) and their level of patriotism. Employing the Goldberg paradigm, participants read identical leadership speeches attributed to either a woman or a man described as either a minority (Black or Latino/a) or a majority (White) group member. Results show social dominance orientation negatively predicted evaluations of minority and female leaders and patriotism positively predicted evaluations of White leaders.  相似文献

Background: Orthographic‐motor integration refers to the way in which orthographic knowledge is integrated with fine‐motor demands of handwriting. A strong relationship has shown to exist between orthographic‐motor integration and students' ability to produce creative and well‐structured written text (De La Paz & Graham, 1995). This relationship is thought to be due to the cognitive load resulting from lack of automaticity in orthographic‐motor integration so that writers do not have sufficient resources to accomplish the more demanding aspects of writing. Interventions to improve children's orthographic‐motor integration result in improved written text (Jones & Christensen, 1999). Aim: This study first extended findings related to handwritten text to the relationship between typing and the length and quality of computer‐based written text. Second, it examined the efficacy of an intervention to develop proficiency in typing skills on the length and quality of students' written language. Sample: Participants in the first study were 276 Grade 8 and 9 students. In the second study 35 students in Grades 8 and 9 who exhibited very low levels of proficiency in typing were the participants. Methods: In Study 1, orthographic‐motor integration related to typing as well as handwriting was assessed for all students. They were asked to complete a piece of handwritten and computer‐based text. Students in the intervention study completed the same measures as Study 1, at pre‐ and post‐test. During the intervention half the students completed a daily typed journal and half completed a program designed to facilitate their typing skills. Results: There was a significant relationship between orthographic‐motor integration — handwriting and the length and quality of handwritten text, and a stronger relationship between orthographic‐motor integration — typing and length and quality of computer‐based text. Both intervention groups in the second study showed significant differences in writing skills from pre‐ to post‐test. However, the typing skills group showed significantly better scores on typing and quality of typewritten text than the journal group at post‐test. The impact of the intervention was specific to typewritten text. There was no difference in length or quality of handwritten text. Conclusion: It is suggested that developing proficiency in orthographic‐motor integration related to typing allows writers to employ their cognitive resources more flexibly when working on a computer, so that they can devote attention to higher‐order processes involved in ideation, syntactic and semantic monitoring and pragmatic awareness.  相似文献

Three studies evaluated Tier 1 early intervention for handwriting at a critical period for literacy development in first grade and one study evaluated Tier 2 early intervention in the critical period between third and fourth grades for composing on high stakes tests. The results contribute to knowledge of research-supported handwriting and composing instruction that informs practice as school psychologists are empowered to embrace the role of intervention specialist. The first study found that neurodevelopmental training (orthographic-free motor activities and motor-free orthographic activities) led to improved accuracy and legibility of letter formation, but that direct handwriting instruction with visual cues and verbal mediation led to improved automatic handwriting (rate of writing legible letters) and transfer to improved word reading. The second study found that neither motor training nor orthographic training alone added value to direct instruction in automatic letter writing and composing practice in developing handwriting skills, which transferred to improved word reading; but the added motor training did improve performance on a grapho-motor planning task for sequential finger movements that is relevant to composing. A related analysis showed that direct instruction with visual cues and memory delays may reduce reversals. A third study found that adding handwriting to reading instruction improved handwriting but did not add value to reading outcomes for at risk readers; reading instruction alone was beneficial for word reading, decoding, and comprehension. The fourth study showed that comprehensive, explicit instruction in the processes of composition led to more significant improvement, based on group and individual data, than did the regular fourth grade program, on high stakes writing assessment.  相似文献

Voters often use visual cues such as facial appearance when forming impressions of political candidates. Originally, psychological research on appearance‐based politics focused on understanding whether or not these facial cues were consequential for political judgments. As this sub‐field of study has expanded, the focus has shifted to understanding how and what facial cues voters utilize in their decision‐making. From this perspective, inferences about political candidates are characterized by a number of interrelated appearance‐based cues such as facial competence, physical attractiveness, and ingrained gender stereotypes that manifest in politicians' appearance. Importantly, this expanded research focus now includes a broader range of evaluative judgments that are influenced by candidates' facial appearance. Here, we provide an overview of the research on the use of appearance‐based cues in political decision‐making including initial information gathered about candidates, the evaluation of candidates' potential to be effective leaders, and the decision of whether or not to support candidates in an election.  相似文献

How does so much gender inequality endure in an era when many laws and policies endorse principles of gender equality? This essay examines this dilemma by considering Susan Moller Okin's criticism of “false gender neutrality,” research on implicit bias, and the shifting relation of gender bias to American law. I argue that these are crucial elements of the modern cycle of gender inequality, enabling it to operate through a perverse “invisible‐hand” mechanism. This framework helps convey how underlying gender bias influences individual behaviors that generate, legitimate, and mask broad patterns of inequality. Contemporary legal conflicts reflect many of these dynamics, which appear in controversies over gender‐based violence (U.S. v. Morrison 2000 ), gender discrimination in pay and promotion (Ledbetter v. Goodyear Tire 2007 ), and women's reproductive health care benefits (Burwell v. Hobby Lobby 2014 ). This analysis advances our understanding of how the contemporary cycle of gender inequality operates, the complex links between individual behavior and structural bias, and the difficulty of pursuing gender justice through prevailing frameworks of law and liberalism. It also underscores the continued importance of feminists' collective work to address “invisible” as well as visible biases.  相似文献

This study examined gender bias on job performance in work settings where confounding variables (e. g., organizational level, experience, education) were cautiously taken into consideration to ensure fair comparisons. Although previous meta‐analyses examined gender biases on evaluations, findings in tightly controlled laboratory environments may differ from those in highly complicated field studies. We found little evidence of overall gender bias in performance appraisals in nonconfounded field studies. However, there were significant pro‐male biases when only men served as raters. Measure‐specific gender stereotypicality, instead of genera! stereotypicality about the job, produced gender bias in performance appraisal. Masculine measures produced pro‐male bias, and feminine measures produced pro‐female bias.  相似文献

The mental model theory postulates that reasoners build models of the situations described in premises, and that these models normally represent only what is true. The theory has an unexpected consequence. It predicts the existence of illusions in inferences. Certain inferences should have compelling but erroneous conclusions. Two experiments corroborated the occurrence of such illusions in inferences about what is possible from disjunctions of quantified assertions, such as, "at least some of the plastic beads are not red." Experiment 1 showed that participants erroneously inferred that impossible situations were possible, and that possible situations were impossible, but that they performed well with control problems based on the same premises. Experiment 2 corroborated these findings in inferences from assertions based on dyadic relations, such as, "all the boys played with the girls."  相似文献

Tablets are increasingly being used in schools for a variety of handwriting tasks. Given that the control of handwriting relies on both visual and proprioceptive feedback, especially in younger writers, this raises the question of whether the texture of the tablet surface affects graphomotor execution. A series of recent studies found that when the smoothness of a tablet screen modifies proprioceptive feedback, the impact on graphomotor execution varies according to the level of the writer’s handwriting skills. However, as the writing on the screen remained visible in these studies, participants may have compensated for the decrease in proprioceptive feedback by relying more heavily on visual information. The aim of the present study was therefore to unravel the respective contributions of different types of sensory feedback during handwriting development and, consequently, the compensatory role of visual information when children and adults have to write on a tablet. To this end, we asked second and fifth graders and adult participants to write letters and pseudowords on a plastic board placed on top of a tablet screen. Participants wrote on either the smooth or the granular side of the plastic board (manipulation of surface friction), and with normal vision or behind a shield that hid the hand and handwriting from direct view (manipulation of vision). Kinematic parameters and legibility were recorded to assess handwriting performances. Results revealed a significant interaction between proprioceptive and visual feedback on letter size, pen speed and legibility, regardless of participants’ age. Furthermore, reducing the visual and proprioceptive feedback had a greater effect on the children’s handwriting performances than on those of adults. Overall, the present study provides new insight into the contribution of the different types of sensory feedback and their interaction with handwriting development. In addition, our results on the impact of tablet surface on graphomotor execution will serve as useful pointers for improving the design of this tool for children, such as increasing the degree of friction of the screen surface.  相似文献

This experiment examined correspondence bias associated with the expression of pro‐ or anti‐American sentiment in the months following September 11, 2001. Participants read a pro‐ or anti‐United States essay written by a person whose name was varied to suggest that he either was or was not a Muslim. Participants were informed either that the position taken in the essay had been chosen or assigned. Inferences made about the essay writer's true opinions demonstrated strong and consistent correspondence bias only when participants believed the essay writer was not a Muslim. When participants believed the essay writer was a Muslim, correspondence bias was diminished on one measure and disappeared completely on another. These findings are consistent with the notion that participants were concerned about rushing to incorrect conclusions about a Muslim target person. The strong correspondence bias exhibited by participants making judgments about a non‐Muslim is consistent with Gilbert and Malone's (1995) assertion that unrealistic expectations lead to correspondence bias.  相似文献

People make trait inferences immediately when observing others’ behaviours. Previous studies reported that this spontaneous trait inference (STI) occurs more strongly from negative behaviours than from positive behaviours. However, what is responsible for this negativity bias in STI is unclear. In this study, two experiments investigated the effects of valence (an event's affective positivity or negativity) and frequency (how frequently the behaviour is observed in everyday life) on the occurrence of STI using an adapted version of a savings‐in‐relearning paradigm. Experiment 1 revealed that only valence affected the frequent occurrence of STI. In addition, the instructions to suppress impression formation or to focus attention on an actor's face made no difference to the results. In Experiment 2, the negativity bias in STIs was shown a week after exposure to the behavioural stimuli. These results suggest that the negativity bias in STIs occurs robustly, and the negative valence of observed behaviour is mostly responsible for the negativity bias in STI. The importance of immediate categorization of negative stimuli is discussed in terms of ecological priority.  相似文献

The capacity of naturalistic research designs to contribute to causal understanding is assessed in relation to evaluating alcohol control policies. Recent conceptual writings on evaluation research emphasize the importance of causal fields and complex models in making probabilistic causal inferences. Several new statistical approaches that promise help in drawing generalizable causal inferences from suitably developed naturalistic and quasi-experimental studies are discussed. Structural equation modeling augmented by automated heuristic search procedures, econometric techniques for selection bias adjustment, and theory-driven outcome pattern analysis are considered. Two examples from alcohol control policy evaluations are given. One involved use of selectivity adjustments to evaluate a highly selectivity-conditioned environmentally-based alcohol abuse prevention program. Many naturalistic evaluations are improved by modeling self-selected program exposure as well as program response. A second evaluation, now in progress, assesses impacts of the U.S. national alcohol warning labels policy. Problems facing the investigation are enumerated, highlighting the need for theorizing about mechanisms of influence, developing multiple lines of evidence, and examining patterns of outcomes for fit with theoretical expectations.  相似文献

Within organizational judgment and decision making contexts, biases based on an evaluated person's attractiveness are among the most salient and frequently investigated. An enormous amount of research indicates favoritism for attractive people compared to unattractive ones. The current research demonstrates that the nature of this bias depends on whether one is evaluating a member of the same sex or the opposite sex. Experiment 1 (n = 2639) investigated selection of scholarship applicants and demonstrated that a pro-attractiveness bias held only for selection of opposite-sex scholarship applicants; no such bias was observed for highly attractive same-sex applicants. Experiment 2 (n = 622) investigated evaluations of prospective job candidates and demonstrated again that pro-attractiveness bias was observed only for opposite-sex candidates; participants discriminated against highly attractive same-sex candidates. Moreover, this bias was not observed among highly attractive participants; it held only for moderately attractive participants, those for whom highly attractive same-sex individuals can pose especially potent social threats. Findings suggest that attractiveness biases in organizational decision making are rooted partly in the social threats and opportunities afforded by attractive people.  相似文献
