An evaluation of multiple‐schedule variations to reduce high‐rate requests in the picture exchange communication system

Using procedures similar to those of Tiger, Hanley, and Heal (2006), we compared two multiple‐schedule variations (S+/S– and S+ only) to treat high‐rate requests for edible items in the Picture Exchange Communication System (PECS). Two individuals with autism participated, after they showed persistent requests for edible items after PECS training. Stimulus control was achieved only with the multiple schedule that involved presentation of a discriminative stimulus during reinforcement components and its removal during extinction components (S+ only). Discriminated requests were maintained for the 1 participant who experienced schedule thinning.     

Developmental surface dyslexia and dysgraphia: An orthographic processing impairment

This study presents a detailed investigation of a young man in his early twenties who has suffered from a severe spelling impairment since childhood, and currently has a spelling age of only 9 years and 2 months. In contrast with the developmental phonological dyslexics reported by Campbell and Butterworth (1985) and Funnell and Davison (1989), his performance on tests of phonological awareness is good. In addition, he can read and spell non-words competently and, unlike normal 9-year-old children, virtually all of his spelling errors are phonologically appropriate. Further analysis of these errors reveals that he has knowledge of many of the different ways in which a given phoneme can be written, and that he uses phoneme-to-grapheme correspondences at the end of a word that are different from those he uses earlier in a word. However, he finds it difficult to spell words that contain uncommon phoneme-to-grapheme correspondences, which is compatible with the view that he has not developed an orthographic spelling lexicon. Although his oral reading of words is prompt and generally accurate, analysis of his lexical decision performance and the way that he defines homophones indicate that he does not have fully specified lexical entries available for reading either. We suggest that he suffers from a general orthographic processing deficit, and relies instead upon the combination of sub-lexical phonology and a lexicon that contains only partial information about way in which words are spelt. This leads to reasonably competent reading, even of many irregular words, but produces very poor spelling. It is argued that qualitatively different types of developmental dyslexia do genuinely exist, but that reading impairments are likely to be much more pronounced in children who have a phonological rather than an orthographic processing deficit.     

Judicial Wisdom: The Process of Constructing Wise Decisions

Surprisingly little research exists on the role of wisdom within legal decision making. To shed light on this topic, we interviewed 11 U.S. judges who were nominated by their peers for their legal wisdom. They were asked to describe their experience of wise legal decision making and the qualities and processes they felt characterize wise judges. Their interviews were subjected to a grounded theory analysis to develop an understanding of the psychological processes and interpersonal performances that constitute wise legal decision making. Among other findings, results identified attitudes in judges that were thought to lead to better decisions, such as an attitude of curiosity. They identified courtroom management styles that were characterized by magnanimity and compassion as instilling public faith in the system, in contrast to a distant or overly adversarial tone. They tended to agree that, when possible and within the confines of the law, rulings oriented toward rehabilitation were preferable to punitive ones. As well, wise judges described the ways they managed personal challenges arising from value conflicts or ambiguous evidence when making decisions. The article provides clarity on the meanings of the term wisdom within the judicial profession and its construction within the alternative discourses of retributive and procedural justice.     

‘It's not that we hate you’: Understanding children's gender attitudes and expectancies about peer relationships

Widespread gender segregation, evident throughout elementary school, seems to imply that girls and boys have negative feelings and thoughts about one another, and classic theories of inter‐group processes support this idea. However, research has generally overlooked children's feelings and perceptions about gender‐related interpersonal interactions. This paper investigates the nature of children's attitudes about same‐ and other‐gender peers, and explores how those attitudes relate to the expectancies and beliefs children hold about same‐ and other‐gender peer interactions. Children (N= 98 fifth graders) completed questionnaires assessing their global liking of own‐ and other‐gender peers ( Yee & Brown, 1994 ), positive and negative attitudes about own‐ and other‐gender peers, and outcome expectancies related to interacting with own‐ and other‐gender peers. Results indicated that rather than being characterized by out‐group negativity, children's inter‐group gender attitudes are best characterized by an in‐group positivity bias. Children's positive and negative affective attitudes were also significantly associated with outcome expectancies. In contrast, global liking of own‐ and other‐gender peers was less predictive of outcome expectancies. Thus, the greater specificity of the affective attitude measures appeared to be a more predictive and potentially fruitful gauge of children's feelings about own‐ and other‐gender peers. Results are discussed in terms of the need for finer grained and more extensive studies of children's gender‐related feelings and cognitions about own‐ and other‐gender peers.     

Partial knowledge in a tip-of-the-tongue state about two- and three-word proper names

Participants in this study attempted to name 44 famous people in response to reading biographical information about them. Half of the celebrities had names that contained two words (e.g., Gwyneth Paltrow and Sean Penn), and half of them had names containing three words (e.g., Catherine Zeta Jones and Billy Bob Thornton). Half of the names had previously been judged to be of high familiarity (e.g., Gwyneth Paltrow), and half were of lower familiarity (e.g., Billy Bob Thornton). The results showed that when in a tip-of-the-tongue (TOT) state, the participants were able to estimate at above-chance rates whether a celebrity’s name comprised two or three words. Accurate information about the number of words was not available to the participants unless they were in a TOT state or had already named the person. Attempts to identify celebrities whose name had three elements were associated with an increased number of TOTs, relative to celebrities whose name had two units, but there was no difference in the number of don’t know responses for names containing two or three words. Calculations based on Gollan and Brown (2006) suggested that having three names impaired the phonological but not the semantic stage of lexical retrieval, whereas low familiarity impaired both semantic and phonological retrieval stages.     

Categorical perception of colour in the left and right visual field is verbally mediated: evidence from Korean

In this study we demonstrate that Korean (but not English) speakers show Categorical perception (CP) on a visual search task for a boundary between two Korean colour categories that is not marked in English. These effects were observed regardless of whether target items were presented to the left or right visual field. Because this boundary is unique to Korean, these results are not consistent with a suggestion made by Drivonikou [Drivonikou, G. V., Kay, P., Regier, T., Ivry, R. B., Gilbert, A. L., Franklin, A. et al. (2007) Further evidence that Whorfian effects are stronger in the right visual field than in the left. Proceedings of the National Academy of Sciences 104, 1097-1102] that CP effects in the left visual field provide evidence for the existence of a set of universal colour categories. Dividing Korean participants into fast and slow responders demonstrated that fast responders show CP only in the right visual field while slow responders show CP in both visual fields. We argue that this finding is consistent with the view that CP in both visual fields is verbally mediated by the left hemisphere language system.     

A practical variation of a multiple-schedule procedure: brief schedule-correlated stimuli

Multiple schedules using continuous discriminative stimuli have been used to minimize children's disruptive requesting for teacher attention (e.g., colored floral leis; Tiger & Hanley, 2004; Tiger, Hanley, & Heal, 2006). The present study evaluated the effectiveness of, and children's preferences for, two multiple-schedule arrangements in which brief experimenter vocalizations served as discriminative stimuli. Results showed that brief signals were highly effective discriminative stimuli for 3 of the 4 children, and that all children preferred one or both variations of the multiple schedule to a control arrangement. For 1 child, highly discriminated responding was achieved only when continuous signals were introduced.
