Are correlated streams of information necessary for implicit sequence learning?

We investigated whether the existence of correlated streams of information is necessary for incidental sequence learning to occur. We ran three separate experiments with a total of 201 undergraduate students. Each experiment had at least one condition with two streams of sequenced information that were correlated. The correlations differed in terms of the kind of responses that were required, the kind of tasks and stimuli, the on-screen locations at which they occurred and how they were combined. Only in conditions with correlated sequences was implicit sequence learning found. Our results suggest that the presence of correlated streams of information may be the main pre-requisite for implicit sequence learning.

A test designed to measure dimensions of intrafamilial attitudes was administered to the parents of 250 children. The children were tested on the School Motivation Analysis Test. Among the many relationships obtained the most consistent predictor of the child SMAT scores was that of interspouse hostility, which was positively related to the children's assertiveness and sex scores and negatively related to childrens' narcism, protectiveness, and superego scores. In the case of the child self-sentiment scores a reversal occurred, with the fathers' interspouse hostility being positively related and the mothers' negatively related. These results must necessarily stand as tentative pending cross-validation; and they are regarded by the authors as hypothesis generating rather than as hypothesis testing. Although the linear multiple regression model used is a powerful one, it would not be unreasonable to expect interactions among some of the family attitude factors and, further, interactions of these factors with sex of the child and family demographic variables.     

The role of attitudes towards the targets of behaviour in predicting and informing prenatal testing choices

Research considering the role of attitudes in prenatal testing choices has commonly focused on the relationship between the attitude towards undergoing testing and actual testing behaviour. In contrast, this study focused on the relationship between testing behaviour and attitudes towards the targets of the behaviour (in this case people with Down syndrome (DS) and having a baby with DS). A cross-sectional, prospective survey of 197 pregnant women measured attitudes towards the targets of prenatal testing along with intentions to use screening and diagnostic testing, and the termination of an affected pregnancy. Screening uptake was established via patient records. Although attitudes towards DS and having a baby with DS were significantly associated with screening uptake and testing and termination intentions, unfavourable attitudes were better than favourable ones at predicting these outcomes. For example, in the quartile of women with the ‘most favourable’ attitude towards people with DS 67% used screening although only 8% said they would terminate an affected pregnancy. Qualitative data suggested that not all women considered personal attitudes towards DS to be relevant to their screening decisions. This finding has implications for the way in which informed choice is currently understood and measured in the prenatal testing context.     

Completely ruled out? Using response time data to investigate biconditional artificial grammar learning

Two experiments are reported on incidental learning using a biconditional artificial grammar (based on Johnstone & Shanks, 2001). Phonological repetition of rule-related letters was encouraged by requiring participants to write down and rehearse each training exemplar aloud for several seconds (Experiment 1). A cover story was introduced emphasising the relatedness of the two halves of each exemplar but without mentioning the rules (Experiment 2). Participants had no explicit knowledge of the rules and grammaticality classification was mostly at chance. Confidence judgements (Experiment 2) did not distinguish between numbers of correct and incorrect responses. The important finding was that response times were faster for grammatical than ungrammatical test exemplars. Results are discussed with reference to phonological phrasing, fluency, and competition between controlled and automatic processes.     

Self‐ratings of sense of direction and route reversal performance

One of the most pervasive beliefs about human way finding is that some people have a natural ability that distinguishes them from others. In this research, we asked children and adults to rate their own sense of direction, a promising index of orientation skills despite its simplicity and reliance on self‐assessment. Ratings were obtained before and after reversal of a newly learned outdoor route. Self‐ratings by children and adults before route reversal only weakly predicted two of a variety of measures of route and bearing knowledge. However, adults' ratings after the route reversal reflected performance on almost all of these same measures. In addition, route reversal performance was easily improved by instructing children and adults during route acquisition to look back in anticipation of the return. The pattern of results suggests that way finders' beliefs about their sense of direction are based on a recollection of the outcomes of the attentive and mnemonic strategies they use.

Identification of letterlike distortions by preschool children.

In two experiments preschool children chose one of two test forms that looked like previously exposed distortions of a letterlike-form. In Exp. I a distance metric was defined to measure the physical discrepancy between forms. It was found that the distance relationship between distortions and particular test forms did not designate the children's choice behavior. In Exp. II the children were able to choose previously exposed distortions when particular test forms contained novel features. The results are related to distinctive feature and prototype hypotheses to account for children's performance in recognizing forms.     

School-Based Mental Health Services: Definitions and Models of Effective Practice

ABSTRACT

School-based mental health services are those delivered by school-employed and community-employed providers in school buildings. With the implementation of provisions of the Patient Protection and Affordable Care Act (2010) that funds school-based health centers, school-based mental health services could become more broadly available in communities throughout the United States. Playing a pivotal role in promoting models for school-based services that maximize benefits to children and adolescents while making efficient use of communities' mental health resources are school psychologists. School psychologists, who recognize and respect the separated development of school and community mental health professions, can foster school–agency partnerships to coordinate children's mental health services that are comprehensive, child centered, family focused, and culturally competent. In this article, we provide three case examples using the Participatory Culture-Specific Intervention Model (B. K. Nastasi, R. B. Moore, & K. M. Varjas, 2004 Nastasi, B. K., Moore, R. B., & Varjas, K. M. (2004). School-based mental health services: Creating comprehensive and culturally specific programs. Washington, DC: American Psychological Association. [Google Scholar]) as exemplars for the implementation of community partnerships providing comprehensive culturally and contextually relevant school-based mental health services.
