Processing Differences between Feature‐Based Facial Composites and Photos of Real Faces

Computer‐generated faces (composites) constructed by select2ing individual facial features (e.g. eyes, nose, mouth) are poorly recognized because this process contrasts with the natural holistic processing of real faces. This result suggests that there should be differences in the cognitive processing of these composites compared with photos of real faces, which would make these stimuli problematic for theories seeking to explain real face processing. We conducted five experiments to test potential conditions for moving composite processing closer to how real face photos are processed, first taking the perspective of researchers who construct composites with a random selection of available features and then taking a perspective closer to police by creating each composite to match a real face photo. Composites with randomly selected features (but configured like real faces) showed no face inversion effect and recognition memory for these composites benefited from increased encoding time, unlike real face photos. Although composites constructed to match real face photos yielded an inversion effect, they still were remembered differently than the photos. Researchers should not use feature‐based composites as proxies for real face photos. We conclude with a discussion of alternative methods of constructing composites.

The Effectiveness of an Explicit Instruction Writing Program for Second Graders

The National Assessment of Educational Progress found that only 25% of 4th, 8th, and 12th grade students were at grade-level writing proficiency (Greenwald et al. 1999). Insufficient writing skill is a major contributor to lack of school and college success. The current study evaluated a modification of Quickwrite (Maloney 1998), a strategic writing program that explicitly teaches students how to brainstorm, plan, draft, and revise within brief time periods. Teachers who did not have knowledge of the study or the participants rated the overall number of story elements included in second-grade students’ stories higher after the intervention. The rate of student writing did not improve. Results were maintained 4 weeks after the intervention.     

Utilization of Hospital-Based Chaplain Services Among Newly Diagnosed Male Veterans Affairs Colorectal Cancer Patients

The aim of the study was to examine utilization of chaplain services among Veterans Affairs patients with colorectal cancer (CRC). In 2009, the Cancer Care Assessment and Responsive Evaluation Studies questionnaire was mailed to VA CRC patients diagnosed in 2008 (67 % response rate). Multivariable logistic regression examined factors associated with chaplain utilization. Of 918 male respondents, 36 % reported utilizing chaplains. Chaplain services were more likely to be utilized by patients with higher pain levels (OR = 1.017; 95 % CI = 0.999–1.035), younger age (age OR = 0.979; 95 % CI = 0.964–0.996), and later cancer stage (early stage OR = 0.743; 95 % CI = 0.559–0.985). Chaplain services are most utilized by younger, sicker patients.     

Preventing Maltreatment with a Community-Based Implementation of Parent–Child Interaction Therapy

The purpose of this study was to examine rates of child abuse and neglect reports following a community implementation of Parent–Child Interaction Therapy (PCIT), an evidence-supported intervention for the prevention of maltreatment. Among a group of families receiving PCIT, predictors of reports were examined including family demographics, course of treatment, changes in clinical measures, and caregiver report for prior maltreatment victimization and perpetration. Participants (n = 120) included families at-risk for future maltreatment with and without prior maltreatment history. Agency case records were linked with state administrative records of child welfare reports. Time to follow-up ranged from 13 to 40 months. Bivariate and multivariate survival analyses were used to model risk for a later report. During the follow-up period, 12.5 % of families had a report for physical abuse or neglect. Reports of prior victimization as a child and prior perpetration as an adult were strong predictors of a report of perpetration after PCIT. Dosage of PCIT and change in clinical measures did not increase risk for a later report. PCIT can be an effective intervention for preventing maltreatment. Family history of child welfare involvement is a prominent factor in assessing risk for future involvement.     

Time-Out for Sibling Aggression: An Analysis of Effective Durations in a Natural Setting

Abstract

Time-out is a ubiquitous strategy to reduce problem behaviors. The current study sought to find the shortest effective duration(s) of time-out for sibling aggression in a community sample of girls ages 3–7. All participants reached a minimum reduction in sibling aggression of 60% after experiencing a 1-minute time-out. The majority (75%) of participants also demonstrated clear reversals of behavior when returned to the baseline condition. The current findings suggest that a 1-minute time-out may be sufficient for low-level sibling aggression in children as old as seven. Limitations include the presence of a graduate assistant during sibling play and unclear generalizability.     

Rejoinder to commentators on structural equations modeling primers: Bentler,Bagozzi, and Fabrigar,Porter, and Norris

In this brief article, I applaud the commentators for the many points they make, their offering additional perspectives, and for expanding the territory of structural equations modeling coverage begun in the Journal of Consumer Psychology primers.     

Structural equations modeling: Fit Indices,sample size,and advanced topics

This article is the second of two parts intended to serve as a primer for structural equations models for the behavioral researcher. The first article introduced the basics: the measurement model, the structural model, and the combined, full structural equations model. In this second article, advanced issues are addressed, including fit indices and sample size, moderators, longitudinal data, mediation, and so forth.     

Amygdala oscillations and the consolidation of emotional memories

The amygdala receives multi-modal sensory inputs and projects to virtually all levels of the central nervous system. Via these widespread projections, the amygdala facilitates consolidation of emotionally arousing memories. How the amygdala promotes synaptic plasticity elsewhere in the brain remains unknown, however. Recent work indicates that amygdala neurons show theta activity during emotional arousal, and various types of oscillations during sleep. These synchronized neuronal events could promote synaptic plasticity by facilitating interactions between neocortical storage sites and temporal lobe structures involved in declarative memory.     

A comparison of conscious and automatic memory processes for picture and word stimuli: a process dissociation analysis

Four experiments were conducted to evaluate explanations of picture superiority effects previously found for several tasks. In a process dissociation procedure (Jacoby, 1991) with word stem completion, picture fragment completion, and category production tasks, conscious and automatic memory processes were compared for studied pictures and words with an independent retrieval model and a generate-source model. The predictions of a transfer appropriate processing account of picture superiority were tested and validated in "process pure" latent measures of conscious and unconscious, or automatic and source, memory processes. Results from both model fits verified that pictures had a conceptual (conscious/source) processing advantage over words for all tasks. The effects of perceptual (automatic/word generation) compatibility depended on task type, with pictorial tasks favoring pictures and linguistic tasks favoring words. Results show support for an explanation of the picture superiority effect that involves an interaction of encoding and retrieval processes.
