Remembering plurals: Unit of coding and form of coding during serial recall

Subjects were required to recall lists of six words which had been presented visually in sequence. One or two of the words might be plural nouns. A substantial number of errors occurred in which the plural form became detached from its original root. This is taken as evidence for a morpheme-based code as opposed to a unitary word code. A significantly high proportion of these errors maintained the form of the plural ( /S/, /Z/ or (ЪZ/) which is considered evidence for a primarily phonological coding of the plural morpheme. There is however a suggestion that on some occasions the plural is coded morphemically—i.e., in a way which does not distinguish between the various plural endings.     

What is right with “deep” dyslexic patients?

Two aphasic adults with a specific acquired dyslexia were given tests requiring the processing of written words and sentences. Despite the general severity of the patients' deficits, some aspects of such processing appear to be relatively well preserved. The patients have particular difficulty reading aloud function words and abstract words; yet in word/nonword discrimination tests, both patients showed normal recognition of function words and one showed normal performance with abstract words. The patients do have a deficit in comprehension of visually presented words and sentences; yet their performance on comprehension tests was considerable and, moreover, showed meaningful relationships with their ability to read aloud.     

Using the teaching interaction procedure to train interventionists to implement the Cool versus Not CoolTM procedure

The teaching interaction procedure is a behavior analytic procedure that has been used to target the development of social skills. The teaching interaction procedure consists of labeling the target skill, providing a meaningful rationale, describing the steps of the target skill, modeling the skill, role‐play, and providing feedback throughout the interaction. Although the teaching interaction procedure has been used to teach a variety of social skills for individuals diagnosed with autism spectrum disorder (ASD), it has only been used to train staff in two studies. The purpose of this study was to evaluate the use of the teaching interaction procedure to teach three interventionists to implement the Cool versus Not Cool? procedure to target the development of social skills for children diagnosed with ASD. The results of a multiple baseline design demonstrated that the teaching interaction procedure was effective for all three interventionists. Results of the child participants' skill acquisition are also provided.     

Versión española del “Task and Ego Orientation in Sport Questionnaire (TEOSQ)” adaptado a Educación Física

Resumen

El propósito de este trabajo es analizar las propiedades psicométricas del TEOSQ, en una muestra española, aplicado al contexto de la educación física escolar. Con ello se pretende determinar si constituye un instrumento válido y fiable para utilizar en futuras investigaciones en la Educación Física. Se administró a 6170 estudiantes representativos de las provincias de Almería, Granada y Murcia de ESO y ESPO, de edades comprendidas entre 12 y 19 años. El análisis factorial confirmatorio apoyó el modelo teórico hipotetizado de dos factores (orientación a la tarea y orientación al ego) para el TEOSQ-12EF. La baja correlación entre los factores demostró la independencia de los mismos y los coeficientes alfa mostraron una consistencia interna aceptable de las dos subescalas. Las pruebas indican que existen diferencias significativas por sexo, los alumnos presentan una mayor orientación al ego que las alumnas.     

Does child verbal ability mediate the relationship between maternal sensitivity and later self‐regulation? A longitudinal study from infancy to 4 years

There is a need to further examine the mechanisms by which maternal sensitivity influences the development of child self‐regulation. This study investigated the role of maternal sensitivity when infants were 10 months old and child verbal ability at 18 months, in relation to various aspects of self‐regulation at 48 months, in a sample of 95 typically developing children (46.3% girls). In particular, the study examined, from a Vygotskian perspective, whether child verbal ability, as measured by receptive and expressive language, mediated the relationship between maternal sensitivity and hot and cool aspects of self‐regulation in the child. As hypothesized, maternal sensitivity predicted child verbal ability, as well as working memory, set shifting, and delay of gratification. Child receptive language predicted set shifting, inhibition, and delay of gratification. In addition, receptive language mediated the relationship between maternal sensitivity and inhibition only. Additive effects of maternal sensitivity and child receptive language in relation to set shifting were found, and a main effect of maternal sensitivity on child delay of gratification. The results add to the body of research suggesting that responsive parenting and child verbal ability are important for the development of self‐regulation, and suggest that different mechanisms may be at work for different aspects of self‐regulation.     

论执行功能及其发展研究

执行功能(executive function,EF)是一个还没有明确定义的概念,但又是一个重要的概念,通常是指个体对思想和行动进行有意识控制的心理过程。目前的主要观点包括神经心理学观点、抑制控制理论、高级认知能力理论(包括工作记忆理论、抑制及工作记忆理论)和认知复杂性和控制理论。主要的研究任务类型包括卡片分类任务、延迟反应任务、基于Stroop任务的冲突反应模式任务、心理理论任务、问题解决任务、“热”执行功能任务等。未来的研究应着重弄清执行功能的本质,结合认知神经科学阐明其与脑神经结构和功能的关系,并从区分“冷”执行功能和“热”执行功能的角度,探讨以情感激活为特点的“热认知”在执行功能中的作用。     

The demonstration of capacity limitation

The study of divided attention has produced many apparent demonstrations of “capacity limitation.” Possible ambiguities in such demonstrations are considered for three major types of experimental situation: simultaneous inputs with separate responses; choice; and classification. Two issues emerge. First, demonstrations always rest on assumptions about process set, i.e., the set of internal processes by which the task actually is performed. Alternative process sets are considered for situations of each type. Second, a demonstration of capacity limitation is made either by increasing the number of simultaneous processes, or by changing the bias between them. In either case effects unrelated to capacity limitation may influence the results. If several processes contribute to a single response, some performance decrement must accompany an increase in their number, simply through the increased overall chance for error. If the subject is biased toward one alternative in a choice or classification situation, the benefits enjoyed by this alternative may reflect not a preferential allocation of attentional capacity, but simply a willingness to decide in favor of this alternative with relatively little evidence.     

The effects of S-R uncertainty in the PRP paradigm: A reply to Kantowitz

Karlin and Kestenbaum (1968) reported a series of apparently complex interactions between S-R uncertainty and RT in an experiment using the psychological refractory period paradigm. McLeod (1977) showed that these effects could be predicted by a parallel processing limited capacity model. Kantowitz (1978) criticised that paper on the grounds that it paid insufficient attention to the predictions of response conflict theory and made no mention of errors.It will be shown (a) that response conflict theory, as described by Kantowitz, fails to predict the effects found by Karlin and Kestenbaum (b) that the comments about errors miss the point of McLeod (1977) (c) that in his final section Kantowitz falls into an old trap which awaits the unwary analyser of PRP data.     

Rhythm and dominance

Subjects were tested by a short experimental procedure involving tapping of a rhythm with one limb with a simultaneous regular beat with another limb. Informal observations had suggested a rhythm dominance effect—that is was dramatically easier with some limb combinations. Notably it was easy when the right hand tapped the rhythm and the left hand the beat but almost impossible the other way round. Equally, both hands dominated both feet. Our tests revealed enormous individual differences, subjects separating neatly into three groups. Some people could not do the task at all, some could do it with any limb combination, the latter group including all the serious musicians tested. For the remainder the rhythm dominance effect was clear. However, the laterality effect was the same (right hand advantage) for a majority (60%) of left handers. We conclude, then, that this effect is linked to language dominance and not handedness. In addition it seems there is a task scheduler which imposes its own view in combining this laterality effect with the dominance of hands over feet.     

Evaluation and training of Executive Functions in genocide survivors. The case of Yazidi children

Executive Functions (EFs) development is critically affected by stress and trauma, as well as the socioeconomic context in which children grow up (Welsh, Nix, Blair, Bierman, & Nelson, 2010, Journal of Educational Psychology, 102 , 43–53). Research in this field is surprisingly lacking in relation to war contexts. This study represents a first attempt at addressing this topic by evaluating EFs in Yazidi children. The Yazidi community is an ethnic and religious minority living in Iraq. From August 2014 onwards, the Yazidi community has been the target of several atrocities perpetrated by ISIS and described as genocide by the international community at large. The University of Trieste, thanks to a program financed by the Friuli Venezia Giulia Region, developed a study aimed at (a) evaluating hot and cool EFs in children living in a war context and (b) developing a specific training method to enhance hot and cool EFs in Yazidi children of preschool age (N = 53). Data related to this group of children were compared with a sample of typically developing Italian children randomly assigned to either an EFs training group (N = 55) or a passive control group (N = 51). Results indicate different baselines in EFs in Yazidi and Italian samples and a significant effect of the program on both trained groups, especially in tasks measuring hot EFs. Data are discussed in terms of hot and cool EFs in children growing in adverse environments, as well as the evaluation of educational and developmental opportunities to prevent children who survived genocide from becoming a ‘lost generation’.
