Lineup administrator influences on eyewitness identification and eyewitness confidence

Lineup administrators were trained to respond to witnesses in such a way as to redirect them from making non-identifications or foil identification responses toward making identifications of the suspect. Compared to a no-influence control condition, suspect identification rates in the influence condition increased substantially and proportionally for guilty and innocent suspects. Administrators steered witnesses more specifically toward the suspect when the suspect was guilty than when the suspect was innocent. Post-identification confidence for correct identifications of the guilty suspect did not differ significantly across the influence and no-influence groups. However, post-identification confidence for false identifications of the innocent suspect was significantly lower for the influence group than for the no-influence group because witnesses who were influenced to make false identifications tended to be those who were less confident prior to the lineup, and also because those witnesses became less confident from pre- to post-identification.     

A neurophysiological explanation for biases in visual localization

Observers show small but systematic deviations from equal weighting of all elements when asked to localize the center of an array of dots. Counter-intuitively, with small numbers of dots drawn from a Gaussian distribution, this bias results in subjects overweighting the influence of outlier dots – inconsistent with traditional statistical estimators of central tendency. Here we show that this apparent statistical anomaly can be explained by the observation that outlier dots also lie in regions of lower dot density. Using a standard model of V1 processing, which includes spatial integration followed by a compressive static nonlinearity, we can successfully predict the finding that dots in less dense regions of an array have a relatively greater influence on the perceived center.     

Psychological testing and psychological assessment. A review of evidence and issues

This article summarizes evidence and issues associated with psychological assessment. Data from more than 125 meta-analyses on test validity and 800 samples examining multimethod assessment suggest 4 general conclusions: (a) Psychological test validity is strong and compelling, (b) psychological test validity is comparable to medical test validity, (c) distinct assessment methods provide unique sources of information, and (d) clinicians who rely exclusively on interviews are prone to incomplete understandings. Following principles for optimal nomothetic research, the authors suggest that a multimethod assessment battery provides a structured means for skilled clinicians to maximize the validity of individualized assessments. Future investigations should move beyond an examination of test scales to focus more on the role of psychologists who use tests as helpful tools to furnish patients and referral sources with professional consultation.     

Reaching Latino Families Through Pediatric Primary Care: Outcomes of the CANNE Parent Training Program

The lack of culturally adapted parenting programs for Latinos contributes to low engagement in effective parenting programs. Criando a Nuestros Niños Hacio el Éxito (CANNE), a culturally adapted program, improves family dynamics by decreasing problematic child behavior and helping parents manage stress. CANNE was delivered with 12 Latino parents of children (age 3–7). Increased attendance and participation resulted in less child behavior problems and parenting stress from preintervention to postintervention. A culturally relevant adaptation of an evidence-based parenting program improved engagement, child behavioral outcomes, and parenting stress. Implications of mental health services in primary care facilities for Latino families are addressed.

Parental Competency as a Mediator in the PACE Parenting Program’s Short and Long-term Effects on Parenting Stress

Higher levels of parenting stress and lower levels of parental competency have been shown to adversely affect a variety of child outcomes such as both externalizing and internalizing behavior problems. Behavioral parent training programs simultaneously decrease parenting stress while increasing parental competency. Recent research has focused on possible mechanisms of change that influence the efficacy of behavioral parent training programs. The present study examined parental competency, specifically parental efficacy and satisfaction, as mechanisms of change in the relationship between attendance in the Parenting Our Children to Excellence (PACE) program and long-term levels of parenting stress. Six hundred and ten parents participated in the PACE parenting program and measures were collected at pre-treatment, post-treatment, and follow-up. Path analysis was utilized to test parental competency as a mediator between engagement in PACE and follow-up parenting stress. Parental satisfaction, one factor of parental competency, was found to be a significant mediator between engagement in PACE and follow-up parenting stress. This study has important implications in further identifying mechanisms of change within behavioral parent training programs.     

Ethnicity differences in child and parental outcomes following involvement the PACE program

This study investigated ethnic differences in the extent to which engagement (i.e., attendance and quality of participation) in the PACE (Parenting our Children to Excellence) program predicted positive child and parent outcomes. PACE is an 8-week preventive intervention aimed at parents of preschool children. The study investigated the relation of engagement to outcomes in an ethnically diverse sample of 298 African American and 280 European American parents. Overall results demonstrated that engagement in PACE significantly improved child and parent outcomes for both African American and European American participants. Some improvements were evident at post-assessment already and were maintained or became stronger at a one-year follow-up assessment, whereas others only became evident at follow-up. Specifically, results revealed that attendance in PACE significantly improved child coping competence and parenting stress for both the African American and European American samples. PACE attendance also significantly improved child behavior problems, parental satisfaction and parental efficacy for the European American sample. Findings indicate that PACE is a promising intervention for parents of African American and Caucasian preschoolers; although further research and program refinement is necessary in order to understand the mechanisms with the PACE intervention that seem to vary for African American compared to Caucasian families.     

The Rorschach: projective technique or psychometric test?

Various approaches to the Rorschach Technique are described in terms of the idiographic-nomothetic axis and the perceptual-content axis. It is suggested that it is most productive to view the Rorschach as a projective tool, with perceptual scoring a secondary factor. Current efforts at objectification of the Rorschach are not seen as useful as efforts to enhance its projective qualities. Some possible ways are discussed in which the projective value of the instrument can be maximized.
