Age differences in emotional reactions: arousal and age-relevance count

Recent findings suggest positivity effects in older adults' attention and memory, but few studies have examined such effects on the level of emotional reactivity. In this study, 52 young and 52 older adults rated 172 pictures of the International Affective Picture System, differing in arousal and age-relevance, in terms of valence and discrete emotions. Age differences in the ratio of pleasantness reactions to pleasant pictures vs. unpleasantness reactions to unpleasant pictures as well as age differences in absolute levels of unpleasantness and pleasantness reactions suggest that positivity effects in older adults' subjective emotional reactions are reduced under high arousal. There is also evidence that positivity effects may be restricted to stimuli with low relevance in old age.     

词汇获得年龄在物体和动作图画命名中的不同作用

本研究目的是考察词汇获得年龄(早与晚)这一因素对物体图画和动作图画命名是否产生了不同的影响。采用物体图画和动作图画命名任务,发现:(1)相比于物体图画命名,动作图画命名的反应时更长,表明动词的产生更为复杂。(2)在物体图画命名任务中,与晚获得词相比,早获得的词产生速度更快;相比而言,在动作图画命名中,晚获得词比早获得词的反应时更短,反应速度更快。基于分析和讨论,我们认为Ao A效应可能发生在图画命名过程中的词汇水平,而非概念水平或反应输出阶段。     

3—7岁儿童不同类型的传递性推理的发展研究

本研究从发展的角度研究了3-7岁儿童在解决三类传递性推理问题时能力发展和策略发展状况,真传递性推理指推理的传递性是确定的,个体根据前提关系可以做出确定的传递性推理结论,不确定性传递性推理指该类推理的传递性是不确定的,关系是否传递需要根据实际的情况和社会经验来确定,否定性传递性推理指根据前提关系得出不能进行传递性的必然结论。结果表明：（1）三类传递性推理的解题能力随年龄的增长而不断增强,在7岁左右初步形成。（2）三类传递性推理,能力发展有不同的起始点、快速发展期以及初步形成期。真传递性推理发展最早最快,不确定传递性推理最晚最慢。（3）3-7岁儿童解决三类传递性推理问题时使用了猜测、视觉判断、定向反应、经验推测和逻辑推理等策略,然而随着年龄的增大,主导策略由准策略向真策略转换。     

Effects of emotional valence and arousal manipulation on eyeblink classical conditioning and autonomic measures

Using a classical eyeblink conditioning paradigm, we have previously shown that the rate of acquisition of a conditioned response may be manipulated by engaging subjects in background tasks of varying complexity concurrent to conditioning. To further examine the influence of the background environment on conditioning, a picture set designed to elicit emotional responses, the International Affective Picture System (IAPS), was presented to subjects during classical eyeblink conditioning. The results suggest that eyeblink conditioning does appear to be sensitive to contextual manipulations of arousal. Pictures rated as very arousing were found to engage subjects enough to enhance learning, although not to the point that autonomic functions were significantly altered between picture groups. We suggest that group differences in learning may be a result of either novelty of, or vigilance to, interesting pictures rather than as a direct result of physiological arousal.

II. The comparability of the WISC-R and WAIS among 16-year-old EMR children

Thirty 16-year-old EMR children were administered the WAIS and WISC-R in counterbalance order to determine the comparability of the two assessment instruments. The WAIS was found to yield significantly higher Verbal, Performance, and Full Scale IQ scores. The comparisons of corresponding subtests indicate that all WAIS subtests were significantly higher than the WISC-R except Picture Completion. Correlations between corresponding WAIS and WISC-R IQ scales and subtests, however, were significant. The results suggest differences between the two instruments among children of subnormal intelligence, thus presenting the possibility that a child may be differentially classified based on the selection of the intelligence test.     

Evaluation of the validity of the Wechsler Intelligence Scale for Children--Third Edition comprehension and picture arrangement subtests as measures of social intelligence

Clinical lore suggests that the Wechsler Intelligence Scale for Children--Third Edition (D. M. Wechsler, 1991) Comprehension and Picture Arrangement scores may be used as indices of social intelligence. This study evaluated this supposition by comparing these subtest scores with mother- and teacher-reported social functioning in 142 children with ADHD and 30 control children. After general intelligence was partialled out, the Comprehension subtest related to some aspects of social functioning, but the clinical significance of this was limited. The Picture Arrangement subtest was unrelated to social functioning, once general intelligence was controlled. These findings were consistent across study groups.     

WAIS picture arrangement and premorbid social competence among process schizophrenics.

A study with male process schizophrenics suggested that the Picture Arrangement (PA) subtest of the WAIS was related to a measure of social competence. There was evidence that the PA subtest may measure an entity such as social intelligence which is different from overall intelligence.     

Do illustrations enhance preschoolers' memories for stories? Age-related change in the picture facilitation effect

This study investigated whether illustrations facilitate story recall in preschoolers (N=58) 46 to 63 months of age. Each child was exposed to either a verbal story narrative with illustrations (Verbal and Picture condition), the narrative alone (Verbal Only condition), the narrative with uninformative illustrations (Verbal and Irrelevant Picture condition), or the illustrations alone (Picture Only condition). Children recalled the story immediately and after a 1-week delay. With increasing age, the Verbal and Picture group increasingly outperformed the other verbal groups, particularly when recalling central details conveyed by both narrative and illustrations. Performance did not vary among the three verbal groups at lower values of age, whereas the Verbal and Picture group recalled more than the other verbal groups at the older ages. Regardless of age, all verbal groups outperformed the Picture Only group, suggesting that preschoolers are unlikely to spontaneously generate a narrative from pictures alone.     

Expressivism and the Layer Cake Picture of Discursive Practice

Robert Brandom defends the intelligibility of the notion of a fully discursive practice that does not include any kind of logical vocabulary. Logical vocabulary, according to his account, should be understood as an optional extra to discursive practice, not as a necessary ingredient. Call this the Layer Cake Picture of the relation of logical to non-logical discursive practices. The aim pursued in this paper is to show, by way of an internal critique, that the Layer Cake Picture is in fact incompatible with the most central claims of Brandom’s philosophy. A way is sketched how to give up the Layer Cake Picture and still hold on to a position that is central to Brandom’s philosophical outlook, namely his expressivism about logic.     

Real-time color-frame animation for visual psychophysics on the Macintosh computer

Psychophysical experiments involving moving stimuli require the rapid presentation of animated sequences of images. Although the Macintosh computer is widely used as a color graphics computer in research laboratories, its animation capabilities are generally ignored because of the speed limitations of drawing to the screen. New off-screen color graphics structures help to avoid the speed limitations so that real-time color or gray-scale visual motion stimuli may be generated. Precomputed animation frames are stored in off-screen memory and then rapidly transferred to the screen sequentially. The off-screen graphics structures may also be saved to disk in “Picture” form as “resources” for later retrieval and playback, allowing the experimenter to build in advance a collection of moving stimuli to use in future experiments. Code examples in the C programming language are provided, and the relative strengths and weaknesses of Macin-tosh color-frame animation for psychophysical experimentation are discussed.     

History of Geometry and the Development of the Form of its Language

The aim of this paper is to introduce Wittgenstein’s concept of the form of a language into geometry and to show how it can be used to achieve a better understanding of the development of geometry, from Desargues, Lobachevsky and Beltrami to Cayley, Klein and Poincaré. Thus this essay can be seen as an attempt to rehabilitate the Picture Theory of Meaning, from the Tractatus. Its basic idea is to use Picture Theory to understand the pictures of geometry. I will try to show, that the historical evolution of geometry can be interpreted as the development of the form of its language. This confrontation of the Picture Theory with history of geometry sheds new light also on the ideas of Wittgenstein. This revised version was published online in June 2006 with corrections to the Cover Date.     

The structure of cognitive abilities in youths with manic symptoms: a factorial invariance study

This study compared the structure of cognitive ability (specifically, verbal/crystallized [Gc] and visual-spatial ability [Gv]), as measured in the Wechsler Intelligence Scale for Children, in youth with manic symptoms with a nationally representative group of similarly aged youth. Multigroup confirmatory factor analysis found the majority of the estimated parameters were invariant between the groups, although there was a difference in the intercepts for the Similarities subtest and difference in unique variances for the Picture Completion, Comprehension, and Picture Arrangement subtests. Thus, although there are many neurological changes associated with manic symptoms, the structure of verbal/crystallized and visual-spatial abilities appear relatively robust and invariant. As Gc and Gv are the primary domains on all the Wechsler Intelligence Scales for Children, results also indicate that clinical interpretation of the Wechsler scales may be appropriate to measure cognitive performance in youths with manic symptoms.     

Does high educational level protect against intellectual decline in older adults?: A 10‐year longitudinal study

This study examined the relation between educational level and intellectual change in Japanese older adults. Participants (age = 65–79 years, n = 593) comprised the first‐wave participants of the National Institute for Longevity Sciences‐Longitudinal Study of Aging (NILS‐LSA). They were followed for 10 years and were tested six times. Educational levels were divided into two groups (low‐educated or high‐educated), and intellectual changes for the 10 years were assessed using the Japanese Wechsler Adult Intelligence Scale‐Revised Short Forms (JWAIS‐R‐SF); subtests included Information, Similarities, Picture Completion, and Digit Symbol. General linear mixed‐model analyses revealed that education had not affected 10‐year changes of the Information, Similarities, and Picture Completion subtest scores. In contrast, education was significantly associated with a change in the Digit Symbol subtest score; individuals with higher levels of education showed greater decline than those with less education, although they had higher ability at every time point. These findings suggest that higher education does not protect against intellectual decline in late life, although it is associated with long‐term individual differences in intelligence.     

Short-term retention of pictures and words as a function of type of distraction and length of delay interval

Picture and word triads were tested in a Brown-Peterson short-term retention task at varying delay intervals (3, 10, or 30 sec) and under acoustic and simultaneous acoustic and visual distraction. Pictures were superior to words at all delay intervals under single acoustic distraction. Dual distraction consistently reduced picture retention while simultaneously facilitating word retention. The results were interpreted in terms of the dual coding hypothesis with modality-specific interference effects in the visual and acoustic processing systems. The differential effects of dual distraction were related to the introduction of visual interference and differential levels of functional acoustic interference across dual and single distraction tasks. The latter was supported by a constant 2/1 ratio in the backward counting rates of the acoustic vs. dual distraction tasks. The results further suggest that retention may not depend on total processing load of the distraction task, per se, but rather that processing load operates within modalities.     

The effect of placement instability on adopted children's inhibitory control abilities and oppositional behavior

This study assessed relations among placement instability, inhibitory control, and caregiver-rated child behavior. The sample included 33 adopted children who had experienced placement instability, 42 adopted children who had experienced 1 stable placement, and 27 children never placed in foster care. Five- and 6-year-old children completed the day-night task, which requires children to inhibit a prepotent response, and a control task that presents similar memory demands but does not require inhibition (C. L. Gerstadt, Y. J. Hong, & A. Diamond, 1994). Adopted children who had experienced placement instability performed worse on the inhibition task than did both other groups of children, when the authors controlled for age, verbal intelligence (as measured with the Wechsler Preschool and Primary Scale of Intelligence--Revised; D. Wechsler, 1989; or the Peabody Picture Vocabulary Test--Third Edition; L. M. Dunn & L. M. Dunn, 1997), and control task performance (p<.01). Children who had experienced placement instability were also rated on the Child Behavior Checklist as more oppositional than other children (p<.01; T. M. Achenbach & L. A. Rescorla, 2000). Inhibitory control did not mediate the association between placement instability and oppositional behavior (p>.05). These results suggest that placement instability may adversely affect the social-emotional development of adopted children.     

Internal evidence of bias in the PPVT-R for Anglo-American and Mexican-American children

This study examines item bias on Forms L and M of the Peabody Picture Vocabulary Test-Revised(PPVT-R) for a sample of Anglo-American and Mexican-American children. Analyses of variance (ANOVA) were employed to assess item bias as defined by items X ethnicity interactions. Follow-up analyses were performed using a Bonferroni-type procedure on individual item contrasts. Bias as measured by differences in item difficulty was found in both groups; however, there was no clear pattern of items that were more difficult for either group. The small number of items that were more difficult for one ethnic group than for the other, coupled with the high reliability of performance overall for both groups, suggest that bias in content of the PPVT-R is minimal.     

Defence strategies and anxiety in mothers of disabled children

The aim of this investigation was to study anxiety and defence strategies in mothers of children with different disabilities. Mothers of children with childhood psychosis, motor handicaps, or Down's syndrome were tested with a projective, percept-genetic technique, viz. the Mother-Child Picture Test (MCPT). Levels of anxiety were measured with the Hospital Anxiety and Depression Scale (HAD). In mothers of psychotic children, the absence of anxiety was significantly associated with misinterpretations and/or failure to recognize the MCPT motif (a close relation between mother and child). This association was not found in the mothers of motor-handicapped children or children with Down's syndrome. The results suggest that, for mothers of psychotic children, the activation of defensive strategies is important to avoid feelings of anxiety evoked by the mother-child situation. For mothers of children with other chronic disabilities, for example, motor handicaps or Down's syndrome, low levels of anxiety may be experienced without the mobilization of strong defensive mechanisms. Different interpretations of the correlation between defence strategies and anxiety in the mothers of psychotic children are discussed.     

A FURTHER EVALUATION OF PICTURE PROMPTS DURING AUDITORY‐VISUAL CONDITIONAL DISCRIMINATION TRAINING

This study was a systematic replication and extension of Fisher, Kodak, and Moore (2007 ), in which a picture prompt embedded into a least‐to‐most prompting sequence facilitated acquisition of auditory‐visual conditional discriminations. Participants were 4 children who had been diagnosed with autism; 2 had limited prior receptive skills, and 2 had more advanced receptive skills. We used a balanced design to compare the effects of picture prompts, pointing prompts, and either trial‐and‐error learning or a no‐reinforcement condition. In addition, we assessed the emergence of vocal tacts for the 2 participants who had prior tact repertoires. Picture prompts enhanced acquisition for all participants, but there were no differential effects on tact emergence. The results support a generality of the effect reported by Fisher et al. and suggest that a variety of learners may benefit from the incorporation of picture prompts into auditory‐visual conditional discrimination training.     

Speech and Language Disorders in Kenyan Children: Adapting Tools for Regions with Few Assessment Resources

This study sought to adapt a battery of Western speech and language assessment tools to a rural Kenyan setting. The tool was developed for children whose first language was KiGiryama, a Bantu language. A total of 539 Kenyan children (males=271, females=268, ethnicity=100% Kigiryama) were recruited. Data were initially collected from 52 children (pilot assessments), and then from a larger group of 487 children (152 cerebral malaria, 156 severe malaria and seizures, 179 unexposed). The language assessments were based upon the Content, Form and Use (C/F/U) model. The assessment was based upon the adapted versions of the Peabody Picture Vocabulary Test, Test for the Reception of Grammar, Renfrew Action Picture Test, Pragmatics Profile of Everyday Communication Skills in Children, Test of Word Finding and language specific tests of lexical semantics, higher level language. Preliminary measures of construct validity suggested that the theoretical assumptions behind the construction of the assessments were appropriate and re-test and inter-rater reliability scores were acceptable. These findings illustrate the potential to adapt Western speech and language assessments in other languages and settings, particularly those in which there is a paucity of standardised tools.
