Using scissors to bisect a line: A perception–action dissociation in complex tool use

Previous research has shown that unilateral visual neglect is improved when patients are required to actively grasp an object at its center, rather than only pointing to its center. A similar dissociation between pointing and grasping responses has been reported for pseudoneglect, a spatial bias toward the left side of space that is normally exhibited by healthy participants. Among other theories, the two-visual-streams hypothesis has been offered as an explanation for these dissociations. According to this hypothesis, highly practiced actions that are performed under easily available visual input (e.g., grasping an object) are controlled by the dorsal stream and can resist perceptual judgment biases. We investigated whether, in pseudoneglect, dissociations between perceptual judgments and motor–manipulative responses occur when participants have to respond with complex tools that are highly practiced but that have been shown to rely on both ventral- and dorsal-stream processing. In a standard line bisection task, participants had to either mark the center of a line with a pencil or cut the line in two halves using a pair of scissors. The results indicated the typical leftward bias (pseudoneglect) in the pencil task, whereas performance was much more accurate in the scissors task. These results show that actions featuring complex tool use can resist perceptual judgment biases, and the findings are discussed with reference to existing accounts of perception–action dissociations.     

A Comparison of Rubrics for Identifying Empirically Supported Practices with Single-Case Research

The use of single-case research methods for validating academic and behavioral interventions has gained considerable attention in recent years. As such, there has been a proliferation of methods for evaluating whether, and to what extent, primary research reports provide evidence of intervention effectiveness. Despite the recent interest in harnessing single-case research to identify empirically supported strategies, examination of these tools has revealed that there is a lack of consistency in the methodological criteria sampled and scoring procedures used to evaluate primary research reports. The present study examined the extent to which various evidence rubrics addressed specific methodological features of single-case research and classified studies into similar evidence categories. Results indicated that the methodological criteria included within rubrics tended to vary, particularly for criteria related to determining the generality of the intervention under study. Moreover, there was substantial discordance observed in the evidence classifications assigned to reviewed studies. These findings are discussed in the context of the still-developing nature of single-case evidence reviews. Recommendations for both research and practice are provided.     

Effects of face and inanimate-object contexts on stimulus–response compatibility

Prior studies have shown that a left–right spatial compatibility effect occurs for vertically oriented stimuli relative to a background context of a face rotated 90° clockwise or counterclockwise from upright. For stimuli presented at the location of the eyes, the mapping of the right eye to a right response and the left eye to a left response, as would be viewed by the participant, yields better performance than does the opposite mapping. An issue of current interest in social cognition is whether animate objects are processed differently from inanimate ones. We investigated this issue in two experiments in which we compared the compatibility effects obtained with inanimate objects to those obtained with animate, face stimuli. The results showed left–right compatibility effects from the participant’s perspective for vehicles and faces from frontal and profile views, as well as for a road sign. Our findings indicate that coding of stimulus location relative to an external frame of reference is not restricted to face backgrounds.     

Latino Foster Parent Health Perceptions of Chronic Conditions: A Qualitative Exploration

Prior work using nationally representative data of children in the child welfare system suggested that Latino foster parents were less likely to identify children in their care as having chronic conditions. Hispanics comprise over one-fifth of children in foster care, the majority of whom have special health care needs, and there is a growing need to recruit qualified Latino families into the child welfare system. Little is known about Latino parents’ health perceptions regarding chronic conditions, and potential reasons for differing identification rates of children with special health care needs. We conducted 17 home-based, in-depth interviews with Latino foster parents to explore health perceptions and cultural beliefs for children in their care around the concept of chronic illness. We found that Latino foster parents’ understanding of conditions that occurred “over and over again” related to emotional and behavioral health problems. In contrast, their perception of “chronic” was associated with terminal, biological conditions that had limited treatment options, such as cancer, HIV, and hepatitis. Latino foster parents did not interpret the survey question on chronic illness as it was intended, and their view of recurrent conditions did not reflect chronic health conditions. Developing survey questions that are culturally sensitive should improve accuracy in assessing chronic health conditions for this high-risk population. Sensitivity to cultural interpretation for this high-needs population is vital to enhancing communication between families and health providers caring for children in foster care.     

‘Play skills’ for shy children: development of a Social Skills Facilitated Play early intervention program for extremely inhibited preschoolers

The aim of the present study was to develop and provide a preliminary evaluation of a social‐skills‐based early intervention program specifically designed to assist extremely inhibited preschoolers. Participants were a sample of n=22 extremely inhibited preschool‐aged children, who were randomly assigned to either the Social Skills Facilitated Play (SST) or Waitlist Control (WLC) condition. As compared to wait‐list controls, extremely inhibited children who participated in the SST‐facilitated play program sessions demonstrated a significantly greater post‐intervention decrease in observed socially wary behaviours and a significantly greater increase in social and socially competent behaviours at preschool. Results are discussed in terms of the importance of developing and refining early intervention programs for extremely inhibited young children. Copyright © 2010 John Wiley & Sons, Ltd.     

The impact of confidence in evaluating on discounting: A missing information context example

• Consumers often use coping mechanisms to aid in processing imperfect information about products when making choices. Specifically, a common evaluation processing pattern of uncertainty detection, uncertainty resolution and discounting behaviour (U–R–D) has been observed, particularly in studies involving missing information (MI). When consumers detect MI (uncertainty), they often discount the MI alternatives unless confidently held inferences are formed to reduce uncertainty (resolution), which attenuates discounting (U–R–D). This paper proposes consumers' overall confidence in evaluating (CE) plays a role in the U–R–D processing pattern. In MI contexts, inferences formed to fill‐in MI may also increase overall CE which may have an effect on discounting that is separate and distinct to that of the formation of confidently held inferences. While the impact on discounting of inferences formed to fill in MI is only relevant in MI contexts, the impact of the more encompassing CE variable may impact non‐MI contexts (affected by non‐MI uncertainty) as well. The concept of CE broadens the scope of the U–R–D processing pattern commonly observed in MI contexts to other evaluation contexts. Two studies demonstrate the role of CE in the U–R–D evaluation process (in MI contexts). A model proposes more general interactive effects of sources of uncertainty, and uncertainty detection and resolution on CE and discounting.

Epilogue

The aim of the study was to examine perceived job insecurity and its antecedents and outcomes over a three-year time period. Job insecurity was operationalized by four scales based on the global and multidimensional definition of job insecurity. The study was carried out by means of questionnaires, which were administered three times, in 1995 (Time 1), 1996 (Time 2), and 1997 (Time 3), to employees in three organizations: a paper mill, a bank, and a municipal social and health care department. The present article is based on the data of those employees (N = 109) who participated in each year of the study. The results indicated that global worry about one's job continuity (global scale) and the probability of negative changes in one's job (probability scale) shared similar elements most and both of them were predicted by low self-esteem over the three-year period. Only the evaluations of the probability of negative job changes led to negative outcomes in occupational well-being later on.     

Differential Decline of Verbal and Visuospatial Processing Speed Across the Adult Life Span

The present study compared the age-related decline in verbal and visuospatial processing speed in 131 participants aged 18 to 90 years. Participants performed four verbal and four visuospatial tasks. Age differences in processing speed were compared at the group and individual levels. For the group-level analyses, participants were divided into a young adult group and six older groups subdivided by decade. The mean verbal and visuospatial response times (RTs) for each group were regressed on the corresponding RTs of the young adult group. The slope of the visuospatial regression was greater than that for the verbal regression at all ages, and the difference between the visuospatial and verbal slopes increased with each decade. For the individual-level analyses, a verbal and a visuospatial processing-time coefficient (Hale & Jansen, 1994) was obtained for each individual, and these values were then regressed on age. Verbal processing time increased linearly by approximately 50% while visuospatial processing time increased exponentially by approximately 500% from 18 to 90 years. Taken together, the results at both the group and the individual level demonstrate that aging affects visuospatial processing to a much greater extent than verbal processing.     

Merging Professional Training and Community Engagement Agendas: A Case Study

This case study explored the emancipatory foundations of community work through a schools-based peer support intervention. We use a case study approach to describe the context in which the intervention was developed, its emancipatory theoretical foundations, and the project's implementation components and process. The findings suggest that reflexivity is a useful tool for community engagement and for articulating tensions that arise in the enactment of community participation, empowerment and conscientisation. The intervention presented a unique opportunity to reflect on the operationalisation of theoretical concepts in community psychology, and to train professional psychologists for reflexive community work.
