Performing action has been found to have a greater impact on learning than observing action. Here we ask whether a particular type of action – the gestures that accompany talk – affect learning in a comparable way. We gave 158 6‐year‐old children instruction in a mental transformation task. Half the children were asked to produce a Move gesture relevant to the task; half were asked to produce a Point gesture. The children also observed the experimenter producing either a Move or Point gesture. Children who produced a Move gesture improved more than children who observed the Move gesture. Neither producing nor observing the Point gesture facilitated learning. Doing gesture promotes learning better than seeing gesture, as long as the gesture conveys information that could help solve the task.  相似文献

In 1994, 4?years after the end of the Civil War, Lebanon passed Presidential Decree 5427 naturalizing over 154,931 foreign residents. During the four parliamentary elections that followed, these naturalized citizens demonstrated a higher rate of voter participation than the native-born population. The current debate on the nativity gap assumes that recent naturalization should indicate lower rates of voter turnout, except when machine politics orchestrates the opposite. In Lebanon, the patron?Cclient system seems to be responsible for this inverse nativity gap.  相似文献

Drawing on the social interaction model, we examine the mediating role that the customer's display of positive emotions plays on the relationship between the employee's display of positive emotions and the employee's positive mood. We also examine the moderating role that the customer's personality traits-agreeableness, extraversion, and emotional stability-play on the relationship between the employee's display of positive emotions and the customer's display of positive emotions. The results show that the customer's display of positive emotions mediates the relationship between the employee's display of positive emotions and the employee's positive mood. In addition, the customer's personality traits moderate the relationship between the employee's display of positive emotions and the customer's display of positive emotions. The customer's display of positive emotions depends less on the employee's display of positive emotions when the customer has high levels of agreeableness and emotional stability than when the customer has low levels of agreeableness and emotional stability.

Even after evidence-based treatment, Attention-Deficit/Hyperactivity Disorder (ADHD) is associated with poor long-term outcomes. These outcomes may be partly explained by difficulties in peer functioning, which are common among children with ADHD and which do not respond optimally to standard ADHD treatments. We examined whether peer rejection and lack of dyadic friendships experienced by children with ADHD after treatment contribute to long-term emotional and behavioral problems and global impairment, and whether having a reciprocal friend buffers the negative effects of peer rejection. Children with Combined type ADHD (N?=?300) enrolled in the Multimodal Treatment Study of Children with ADHD (MTA) were followed for 8 years. Peer rejection and dyadic friendships were measured with sociometric assessments after the active treatment period (14 or 24 months after baseline; M ages 9.7 and 10.5 years, respectively). Outcomes included delinquency, depression, anxiety, substance use, and general impairment at 6 and 8 years after baseline (Mean ages 14.9 and 16.8 years, respectively). With inclusion of key covariates, including demographics, symptoms of ADHD, ODD, and CD, and level of the outcome variable at 24 months, peer rejection predicted cigarette smoking, delinquency, anxiety, and global impairment at 6 years and global impairment at 8 years after baseline. Having a reciprocal friend was not, however, uniquely predictive of any outcomes and did not reduce the negative effects of peer rejection. Evaluating and addressing peer rejection in treatment planning may be necessary to improve long-term outcomes in children with ADHD.  相似文献

McClelland??s (1976) power-stress theory proposes that persons high in need for power experience severe stress in the face of actual or anticipated social events that thwart their need to exert control or influence over others, or to achieve recognition for power-oriented behaviors. Guided by McClelland??s theory, we conducted a simulated dating service experiment with college men who scored either high or low on the Picture Story Exercise (PSE) measure of power motivation and later observed a video displaying an interview with a hypothetical dating partner. From among the 203 men who completed the PSE, 96 took part in the experiment. The video presented an 8-min enactment by a young woman who came across either as an assertive feminist or as compliant and agreeable. Electromyographic responses from the corrugator supercilii (frown muscles) fit the premise of McClelland??s power-stress theory, as did scores on the Reysen Likability Scale and the Affective Attitudes Scale.  相似文献

Six- and nine-yr.-old children (n=28 of each) were divided into equal experimental and control groups. The experimental groups were shown a film with a magical theme, and the control groups were shown a film with a nonmagical theme. All groups then were presented with a choice task requiring them to discriminate between ordinary and fantastic visual displays on a computer screen. Statistical analyses indicated that mean scores for correctly identifying the ordinary and fantastic displays were significantly different between experimental and control groups. The children in the experimental groups who watched the magical film had significantly higher scores on correct identifications than children in the control groups who watched the nonmagical film for both age groups. The results suggest that watching films with a magical theme might enhance children's sensitivity toward the fantasy/reality distinction.  相似文献

Previous research has shown that individual differences in life history strategies co-vary with a large array of variables to the extent that latent variables from a number of psychological measures load on a single (Super-K) factor. Similar to research on the Super-K factor, the purpose of this study was to test the hypothesis that various measures of identity would load on a single factor and that this latent variable would in turn be associated with other variables reflecting life history strategy and psychological well-being, making a Super-K factor. A sample of 248 university students were administered a variety of questionnaires related to identity, life history strategy, and psychological well-being. Confirmatory factor analyses revealed the hypothesized Super-K factor and the relationship remained even when controlling for variance in social-desirable responding. The results are discussed in terms of the association between Erikson’s theory of psychosocial development and life history theory.  相似文献

The experiments conducted aimed to investigate whether reduced accuracy when counting stimuli presented in rapid temporal sequence in adults with dyslexia could be explained by a sensory processing deficit, a general slowing in processing speed or difficulties shifting attention between stimuli. To achieve these aims, the influence of the inter-stimulus interval (ISI), stimulus duration, and sequence length were evaluated in two experiments. In the first that used skilled readers only, significantly more errors were found with presentation of long sequences when the ISI or stimulus durations were short. Experiment 2 used a wider range of ISIs and stimulus durations. Compared to skilled readers, a group with dyslexia had reduced accuracy on two-stimulus sequences when the ISI was short, but not when the ISI was long. Although reduced accuracy was found on all short and long sequences by the group with dyslexia, when performance on two-stimulus sequences was used as an index of sensory processing efficiency and controlled, group differences were found with presentation of stimuli of short duration only. We concluded that continuous, repetitive stimulation to the same visual area can produce a capacity limitation on rapid counting tasks in all readers when the ISIs or stimulus durations are short. While reduced accuracy on rapid sequential counting tasks can be explained by a sensory processing deficit when the stimulus duration is long, slower processing speed in the group with dyslexia explains the greater inaccuracy found as sequence length is increased when the stimulus duration is short.  相似文献

Teaching moral reasoning through gesture   总被引:1,自引:0,他引:1  
Stem‐cell research. Euthanasia. Personhood. Marriage equality. School shootings. Gun control. Death penalty. Ethical dilemmas regularly spark fierce debate about the underlying moral fabric of societies. How do we prepare today's children to be fully informed and thoughtful citizens, capable of moral and ethical decisions? Current approaches to moral education are controversial, requiring adults to serve as either direct (‘top‐down’) or indirect (‘bottom‐up’) conduits of information about morality. A common thread weaving throughout these two educational initiatives is the ability to take multiple perspectives – increases in perspective taking ability have been found to precede advances in moral reasoning. We propose gesture as a behavior uniquely situated to augment perspective taking ability. Requiring gesture during spatial tasks has been shown to catalyze the production of more sophisticated problem‐solving strategies, allowing children to profit from instruction. Our data demonstrate that requiring gesture during moral reasoning tasks has similar effects, resulting in increased perspective taking ability subsequent to instruction.
