Effects of Pinyin and First Language Words in Learning of Chinese Characters as a Second Language

This study examined the roles of pinyin and English words as stimulus prompts in the learning of Chinese characters. Recall for naming of English words and pronunciation was enhanced under conditions in which each character was presented first and its prompts were given as feedback, in contrast to simultaneous presentation conditions. Pronunciation was also recalled more in the written pinyin conditions than the verbal pronunciation conditions. These data were interpreted in terms of (a) interference which can occur when learners attend to multiple inputs simultaneously, and (b) the beneficial effects of attending to character prior to their prompts. It was concluded that the presentation of a character first and the provision of its associated prompts as a feedback improves learning.     

Reducing assaults on an acute psychiatric unit using a token economy: a 2‐year follow‐up

Token economies are an effective way of changing various behaviors including acquiring new skills, reducing undesired behaviors, reducing aggression, increasing treatment compliance, and improving psychiatric unit management. This study examines the long‐term effect of a token economy on an acute care, inpatient psychiatric unit. The two years following the implementation of a unit based token economy are compared with the 12 months prior to implementation. The results show a significant reduction in total assaults as well as fewer staff injuries resulting in loss of time from work. Copyright © 2003 John Wiley & Sons, Ltd.     

Mood in foreign exchange trading: Cognitive processes and performance

This paper examines the effects of mood on the behavior of traders or decision makers in financial markets. Based on a review of the psychological theories and empirical findings which relate mood to decision making and information processing, we derive hypotheses with respect to the impact of good, neutral, and bad moods on the behavior of traders. Two experiments (N=66 and 72) were conducted on an Internet platform which simulated foreign exchange trading based on historical market data. The first experiment manipulated mood using feedback and music whereas the second one asked subjects to read mood-laden statements. It was found that traders in a good mood had an inferior trading performance (losing money) compared to those in a neutral or bad mood (making profit). This is because traders in a good mood made less accurate decisions than those in neutral or bad moods. Those in a bad mood were the most accurate in their decisions but behaved conservatively in their trading. Subjects in a good mood tended to make less accurate decisions though they spent on average at least the same time as the other subjects on information processing and decision-making. They also were over-confident taking unwarranted risks. The studies concluded with insights concerning the effects of mood on choice of trading strategies.     

Mental reinstatement of the misinformation context and the misinformation effect in children and adults

The present study investigated the effects of mental reinstatement of the context in which misleading information about an event was presented on later recognition memory for the event. Five‐year‐olds, 7‐year‐olds and adults were shown a short video depicting a children's adventure and were asked a set of misleading questions to introduce misinformation one week later. Before the recognition memory test was administered another week later, half of the participants were given instructions to mentally reinstate the context of the misleading interview. Memory was assessed with a set of forced‐choice recognition questions once in the misleading interview context and for the children a second time at home one week later. When participants were instructed to mentally reinstate the context of the misleading interview prior to the recognition test, false memory reports occurred more often for adults than for children and had a stronger impact on peripheral information than on central information for both 7‐year‐olds and adults. When 5‐ and 7‐year‐olds were tested at home, false memory reports decreased. Thus, reinstating the context of an interview introducing misinformation can reduce the accuracy of memory reports; the context dependence of both accurate and inaccurate memory reports in children and adults is discussed.

Exploring the time prediction process: the effects of task experience and complexity on prediction accuracy

Whilst considerable research shows that people tend to underestimate their task completion times, there is little research concerning factors that mediate the time prediction process. In Experiments 1 to 3 a simple, well‐structured task, the 3‐disk Tower of Hanoi, showed no evidence of underestimation; in fact, participants consistently overestimated the duration of this task. However, predictions were more accurate among participants who acquired some task experience beforehand. Task complexity was also found to be an important factor since the more cognitively complex 4‐ and 5‐disk versions produced less biased predictions. Using a cognitively undemanding disk movement task, we found a general temporal overestimation in Experiment 4, thus suggesting that task duration might be responsible for the general lack of underestimation in the present studies. These results have implications for the planning of tasks in everyday life, and also suggest conditions under which time prediction accuracy can be improved.

Parental Cognitive Errors Mediate Parental Psychopathology and Ratings of Child Inattention

We investigate the Depression‐Distortion Hypothesis in a sample of 199 school‐aged children with ADHD‐Predominantly Inattentive presentation (ADHD‐I) by examining relations and cross‐sectional mediational pathways between parental characteristics (i.e., levels of parental depressive and ADHD symptoms) and parental ratings of child problem behavior (inattention, sluggish cognitive tempo, and functional impairment) via parental cognitive errors. Results demonstrated a positive association between parental factors and parental ratings of inattention, as well as a mediational pathway between parental depressive and ADHD symptoms and parental ratings of inattention via parental cognitive errors. Specifically, higher levels of parental depressive and ADHD symptoms predicted higher levels of cognitive errors, which in turn predicted higher parental ratings of inattention. Findings provide evidence for core tenets of the Depression‐Distortion Hypothesis, which state that parents with high rates of psychopathology hold negative schemas for their child's behavior and subsequently, report their child's behavior as more severe.     

Outcome summaries of latency‐based functional analyses conducted in hospital inpatient units

Latency‐based functional analysis (FA) may be a viable alternative to the standard, rate‐based, FA when frequently evoking problem behavior is not advisable. We conducted 18 latency‐based FAs of the problem behavior of children diagnosed with autism in inpatient hospital settings and identified functional relations during 44.4% (8 of 18) of latency‐based FAs. Implications for conducting FAs of severe problem behavior are discussed.     

A Statistical Consideration Regarding the Threshold of the Psychopathy Checklist–Revised

The Psychopathy Checklist–Revised (PCL–R; Hare, 2003 Hare, R. D. (2003). Hare Psychopathy Checklist–Revised technical manual (2nd ed.). Toronto, ON, Canada: Multi-Health Systems. [Google Scholar]) is one of the most commonly used measures of psychopathy. Scores range from 0 to 40, and legal and mental health professionals sometimes rely on a cut score or threshold to classify individuals as psychopaths. This practice, among other things, assumes that all items contribute equally to the overall raw score. Results from an item response theory analysis (Bolt, Hare, Vitale, &; Newman, 2004 Bolt, D. M., Hare, R. D., Vitale, J. E., &; Newman, J. P. (2004). A multigroup item response theory analysis of the Psychopathy Checklist–Revised. Psychological Assessment, 16, 155–168. doi:10.1037/1040-3590.16.2.155[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]), however, indicate that PCL–R items differ in the amount of information they can provide about psychopathy. We examined the consequences of these item differences for using a cut score, detailing the consequences for a previously applied cut score of 30 as an example. Results indicated that there were more than 8.5 million different response combinations that equaled 30 and more than 14.2 million that equaled 30 or more. This raw score, like others, corresponded to a broad range of PCL–R-defined psychopathy, indicating that applying cut scores on this measure results in imprecise quantifications of psychopathy. We show that by using the item parameters along with an individual's particular scores on the PCL–R items, it is possible to arrive at a more precise understanding of an individual's level of psychopathy on this instrument.     

Violent Attitudes and Antisocial Behavior: Examining the Code of the Street’s Generalizability among a College Sample

Drawing on Elijah Anderson’s (1999) Code of the Street thesis, this study assesses the generalizability of street code attitudes. Using a sample of college students from a large Midwest university, the current study contributes to the literature by examining: (1) the generalizability of street code attitudes; (2) the correlates of street code attitudes, including various forms of strain; and (3) the predictive power of street code attitudes on criminal and non-criminal behavior. Our results reveal that street code attitudes are generalizable to college students, strain constructs are important correlates of street code attitudes, and street code attitudes are associated with criminal behavior. However, the effect of street code attitudes on criminal behavior becomes non-significant once measures of strain are included. Further, street code attitudes do not predict non-criminal behavior.     

Categorical Perception Beyond the Basic Level: The Case of Warm and Cool Colors

Categories can affect our perception of the world, rendering between‐category differences more salient than within‐category ones. Across many studies, such categorical perception (CP) has been observed for the basic‐level categories of one's native language. Other research points to categorical distinctions beyond the basic level, but it does not demonstrate CP for such distinctions. Here we provide such a demonstration. Specifically, we show CP in English speakers for the non‐basic distinction between “warm” and “cool” colors, claimed to represent the earliest stage of color lexicon evolution. Notably, the advantage for discriminating colors that straddle the warm–cool boundary was restricted to the right visual field—the same behavioral signature previously observed for basic‐level categories. This pattern held in a replication experiment with increased power. Our findings show that categorical distinctions beyond the basic‐level repertoire of one's native language are psychologically salient and may be spontaneously accessed during normal perceptual processing.
