Comparing and combining retrieval practice and the keyword mnemonic for foreign vocabulary learning

Experiment 1 compared the effectiveness of retrieval practice, the keyword mnemonic and rote rehearsal for learning foreign language vocabulary. Both mnemonic methods produced similar recall and were superior to rote rehearsal. In Experiment 2, participants learned German vocabulary using keywords, retrieval practice or their own method. Retrieval practice and keyword‐based recall were similar and superior to self‐directed study. In Experiment 3, participants studied using keywords, retrieval practice, a combination or an elaboration strategy. Criterion testing occurred immediately and after a week. For receptive learning, retrieval practice and keywords were equally beneficial but for productive learning, retrieval practice was more effective. Combining strategies produced mixed results with significant benefits only for receptive learning in the delayed test. Copyright © 2006 John Wiley & Sons, Ltd.     

Required sample size to detect the mediated effect

Mediation models are widely used, and there are many tests of the mediated effect. One of the most common questions that researchers have when planning mediation studies is, "How many subjects do I need to achieve adequate power when testing for mediation?" This article presents the necessary sample sizes for six of the most common and the most recommended tests of mediation for various combinations of parameters, to provide a guide for researchers when designing studies or applying for grants.     

Constructing personality scales under the assumptions of an ideal point response process: toward increasing the flexibility of personality measures

The main aim of this article is to explicate why a transition to ideal point methods of scale construction is needed to advance the field of personality assessment. The study empirically demonstrated the substantive benefits of ideal point methodology as compared with the dominance framework underlying traditional methods of scale construction. Specifically, using a large, heterogeneous pool of order items, the authors constructed scales using traditional classical test theory, dominance item response theory (IRT), and ideal point IRT methods. The merits of each method were examined in terms of item pool utilization, model-data fit, measurement precision, and construct and criterion-related validity. Results show that adoption of the ideal point approach provided a more flexible platform for creating future personality measures, and this transition did not adversely affect the validity of personality test scores.     

Preadolescents' and adolescents' online communication and their closeness to friends

The 1st goal of this study was to investigate how online communication is related to the closeness of existing friendships. Drawing from a sample of 794 preadolescents and adolescents, the authors found that online communication was positively related to the closeness of friendships. However, this effect held only for respondents who primarily communicated online with existing friends and not for those who mainly talked with strangers. The 2nd goal was to refine 2 opposing hypotheses, the rich-get-richer and the social compensation hypotheses. Consistent with the rich-get-richer hypothesis, socially anxious respondents communicated online less often than did nonsocially anxious respondents. However, socially anxious respondents perceived the Internet as more valuable for intimate self-disclosure than did nonsocially anxious respondents, and this perception in turn led to more online communication. This result is consistent with the social compensation hypothesis. Online communication and closeness to friends increased with age. There was a curvilinear relationship between age and perceived value of the Internet for intimate self-disclosure, such that 15-year-olds were at the epitome of online self-disclosure. Girls were closer to friends and more socially anxious than were boys.     

Scanning the "Fringe" of consciousness: what is felt and what is not felt in intuitions about semantic coherence

In intuitions concerning semantic coherence participants are able to discriminate above chance whether a word triad has a common remote associate (coherent triad) or not (incoherent triad). These intuitions are driven by increased fluency in processing coherent triads compared to incoherent triads, which in turn triggers a brief and short positive affect. The present work investigates which of these internal cues, fluency or positive affect, is the actual cue underlying coherence intuitions. In Experiment 1, participants liked coherent word triads more than incoherent triads, but did not rate them as being more fluent in processing. In Experiment 2, participants could intuitively detect coherence when they misattributed fluency to an external source, but lost this intuitive ability when they misattributed affect. It is concluded that the coherence-induced fluency by itself is not consciously experienced and not used in the coherence intuitions, but the fluency-triggered affective consequences.     

Distinguishing Between Higher and Lower Risk Youth Offenders: Applications for Practice

The authors report the development of an assessment process for distinguishing between higher and lower risk youth offenders through the use of 3 measures. Preliminary results and applications for practice are included.     

Teaching caregivers to respond safely during agitated states before aggression using simulation training

Individuals who engage in aggression often display precursors or agitated behavior first, and it is important for caregivers to learn how to minimize risk of injury in the event that aggression were to occur. In this study, behavioral skills training was used to teach 4 caregivers of children who engage in aggression to position their body safely and prevent access to dangerous items during agitated states. Confederates were used during all baseline, training, and posttraining sessions to maintain consistency and the safety of the caregivers. All caregivers quickly learned to use these safety skills during agitated periods but not during calm periods with minimal between-session feedback regarding correct responding.
