Recent work on testing effects has shown that retrieval practice can facilitate memory even for complex prose materials (Roediger & Karpicke, 2006a, 2006b). In three experiments the current study explores the effectiveness of retrieval practice on fill-in-the-blank (FITB) tests requiring the recall of specific words or phrases from a text. Final tests included both repeated items that were directly taken from initial tests, and related items. In Experiment 1, with a 2-day delay between initial and final tests, FITB testing benefited performance only on repeated items. In Experiment 2 a 7-day delay between testing sessions led to more robust effects on repeated items. However, once again no benefits were seen for related items. In Experiment 3 the scope of retrieval was varied by comparing FITB tests to paragraph recall tests requiring retrieval of all sentences following a topic sentence. Only the more open-ended recall practice demonstrated improvements in transfer to novel questions. The results suggest that scope or type of processing required during retrieval practice is likely a critical factor in whether testing will have specific or robust benefits. 相似文献

Literature regarding fathers of children with autism remains sparse, and because mothers are the more common intervening parent,
few training methods have focused on fathers. Thus, we sought to evaluate effects of in-home training directed at fathers
and their ability to train mothers in the same manner in which they were trained. Fathers were taught four skills commonly
associated with in-home training interventions for parents of children with autism: following the child’s lead, imitation
with animation, commenting on the child, and expectant waiting. Father skills were evaluated twice a week for 12 weeks during
videotaped in-home father–child play sessions. Analyses included visual inspection of graphed data and statistical analyses
of father skill acquisition, mother skill acquisition, and child behaviors with both parents. A multivariate repeated measures
analysis of 18 dyads revealed significant increases in frequencies of fathers’ imitation with animation, expectant waiting,
and commenting on the child. Child initiating rates increased significantly as did frequencies of child non-speech vocalizations.
Analysis of mothers revealed significant increases in frequencies of imitation with animation, expectant waiting, and following
the child’s lead. Child behaviors had similar results for father and mother sessions. Findings are consistent with those from
our first study indicating that fathers can effectively implement skills that promote father–child social interactions and
that children respond positively to this approach. 相似文献

Undergraduate students in a Southeastern US University (n = 232) responded to an inventory that included retrospective measures of their parents’ style of parenting (authoritarian
vs. authoritative) and their own childhood psychological tendencies (insecurity vs. confidence), as well as their adult stressors
and political orientation. Authoritative parenting positively correlated with childhood confidence and negatively correlated
with both childhood insecurity and adult stressors. Conversely, authoritarian parenting was positively associated with childhood
insecurity and adult stressors but was not significantly correlated with childhood confidence. For the most part, parenting
styles, early childhood tendencies, and adult stressors were unrelated to adult political ideology, contrary to previous longitudinal
research reporting these connections. 相似文献

We examined whether temporal integration of face parts reflects holistic processing or response interference. Participants
learned to name two faces “Fred” and two “Bob.” At test, the top and bottom halves of different faces formed composites and
were presented briefly separated in time. Replicating prior findings (Singer & Sheinberg, Vision Research, 46, 1838–1847, 2006), naming of the target half for aligned composites was slowed when the irrelevant half was from a face with a different name
rather than from the original face. However, no interference was observed when the irrelevant half had a name identical to
the name of the target half but came from a different learned face, arguing against a true holistic effect. Instead, response
interference was obtained when the target half briefly preceded the irrelevant half. Experiment 2 confirmed a double dissociation of holistic processing versus response interference for intact faces versus temporally separated
face halves, suggesting that simultaneous presentation of facial information is critical for holistic processing. 相似文献

A changing criterion design was used to examine the effects of two stimuli (a green card and a red card), conditioned via discrimination training, on reducing motor and vocal stereotypy in a youngster with autism while he looked at books. During discrimination training, motor and vocal stereotypy was not interrupted in the presence of a green stimulus, but was interrupted in the presence of a red stimulus using manual guidance and appropriate behavior was reinforced. After the participant demonstrated successful discrimination of the stimuli (i.e., the absence of stereotypy in the presence of a red stimulus and the engagement in stereotypy in the presence of a green stimulus), intervention began. During intervention, upon meeting criterion for latency to engage in motor and vocal stereotypy in the presence of the red stimulus for a target duration, the participant was provided access to the green stimulus, which signaled that motor and vocal stereotypy would not be interrupted. The criterion latency to engage in stereotypy in the presence of the red stimulus was systematically increased. Simultaneously, the duration of access to the green stimulus was systematically decreased. The red and green stimuli were faded from poster boards to colored 10 × 10 cm cards, and stimulus control was generalized to the participant's classroom and to a community setting (i.e., public library). Results are discussed in terms of discrimination training as a useful intervention for reducing motor and vocal stereotypy. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献

Few empirical studies have explored the mechanisms through which racial identity, the importance of racial group membership, affects well-being for racial/ethnic minorities. Using a community sample of 161 African American adults, the present study examined whether the association between racial identity (centrality, public regard, and private regard) and life satisfaction is mediated by two identity functions, belongingness and discrimination. Our results indicated that the relationships of centrality and private regard with life satisfaction were mediated by perceptions of belongingness. Furthermore, gender moderated the strength of each of these mediating effects, such that belongingness mediated these relationships for women but not for men. Our results also indicated that the relationship between public regard and life satisfaction was mediated by perceptions of discrimination. Furthermore, higher public regard was related to lower perceptions of discrimination for women but not men. However, a combined model for public regard and life satisfaction as mediated by discrimination failed to show moderated mediation. We discuss these results in relation to research and theory on racial identity and intersectionality. 相似文献

Inhibiting unwanted thoughts, actions and emotions figures centrally in daily life, and the prefrontal cortex (PFC) is widely viewed as a source of this inhibitory control. We argue that the function of the PFC is best understood in terms of representing and actively maintaining abstract information, such as goals, which produces two types of inhibitory effects on other brain regions. Inhibition of some subcortical regions takes a directed global form, with prefrontal regions providing contextual information relevant to when to inhibit all processing in a region. Inhibition within neocortical (and some subcortical) regions takes an indirect competitive form, with prefrontal regions providing excitation of goal-relevant options. These distinctions are crucial for understanding the mechanisms of inhibition and how they can be impaired or improved. 相似文献
