Enhancing the credibility of complainants in child sexual assault trials: the effect of expert evidence and judicial directions

This study investigated the knowledge and misconceptions of jury‐eligible citizens about children's reliability as witnesses and responses to child sexual assault (CSA), and examined the influence of expert evidence and judicial directions in challenging common misconceptions. Community volunteers (N = 130) read one of five versions of a simulated jury trial, and completed a pre‐ and post‐trial questionnaire to provide measures of their knowledge of children's responses to sexual abuse, perceptions of victim credibility, and verdict. Results revealed that endorsement of CSA misconceptions negatively impacted ratings of complainant credibility and verdicts. Judicial directions provided before the child complainant testified enhanced complainant credibility, which in turn predicted guilty verdicts. Comparisons of the effectiveness of two procedural legal mechanisms to manage juror misconceptions and improve knowledge about CSA provide guidance for future researchers investigating ways to increase fairness in cases of CSA.

Development and Psychometric Evaluation of the Suicide Anger Expression Inventory—28

We conducted 4 studies to develop and cross-validate scores on a multidimensional self-report measure of suicide and anger expression, the Suicide Anger Expression Inventory-28 (SAEI-28). The SAEI-28 evaluates Suicide Rumination, Maladaptive Expression, Reactive Distress, and Adaptive Expression with 7 content specific items each. Participants were between ages 14 and 47 years old. Study 1 developed a pool of content relevant and representative items for the new inventory. Study 2 explored potential domains of the SAEI-28 items, evaluating preliminary estimates of internal consistency reliability. Study 3 examined specific structures of the SAEI-28 items and scale reliability. Study 4 evaluated the fit of the oblique 4-factor model to 2 alternative solutions. Support was found for estimates of internal consistency reliability for the scales. Criterion-related validity and potential correlates for the SAEI-28 scales were also assessed.     

Value associations of irrelevant stimuli modify rapid visual orienting

In familiar environments, goal-directed visual behavior is often performed in the presence of objects with strong, but task-irrelevant, reward or punishment associations that are acquired through prior, unrelated experience. In a two-phase experiment, we asked whether such stimuli could affect speeded visual orienting in a classic visual orienting paradigm. First, participants learned to associate faces with monetary gains, losses, or no outcomes. These faces then served as brief, peripheral, uninformative cues in an explicitly unrewarded, unpunished, speeded, target localization task. Cues preceded targets by either 100 or 1,500 msec and appeared at either the same or a different location. Regardless of interval, reward-associated cues slowed responding at cued locations, as compared with equally familiar punishment-associated or no-value cues, and had no effect when targets were presented at uncued locations. This localized effect of reward-associated cues is consistent with adaptive models of inhibition of return and suggests rapid, low-level effects of motivation on visual processing.     

Phonology is fundamental in skilled reading: Evidence from ERPs

Research consistently indicates the importance of phonological processing in early reading development, yet the role of phonology in skilled reading is still not well understood. Two event-related potential (ERP) experiments investigated the nature and time course of phonological processing during skilled visual word recognition using a masked priming paradigm. Phonological syllable priming was examined by presenting prime-target pairs either with the same first syllable, or with one letter more or fewer. In this visually matched design, items like po## -PONY and pon### -PONDER appeared in the congruent condition. Conversely, pon# -PONY and po#### -PONDER appeared in the incongruent condition. In both experiments, the magnitude of the first negative peak (N1) was reduced in the phonologically congruent condition as compared to the incongruent condition. This syllable congruency effect is the first neurophysiological evidence for phonological syllable activation in the initial moments of visual word recognition. The early time course of this activation indicates that suprasegmental phonological processing is fundamental to skilled reading.     

Memory Errors Reveal a Bias to Spontaneously Generalize to Categories

Much evidence suggests that, from a young age, humans are able to generalize information learned about a subset of a category to the category itself. Here, we propose that—beyond simply being able to perform such generalizations—people are biased to generalize to categories, such that they routinely make spontaneous, implicit category generalizations from information that licenses such generalizations. To demonstrate the existence of this bias, we asked participants to perform a task in which category generalizations would distract from the main goal of the task, leading to a characteristic pattern of errors. Specifically, participants were asked to memorize two types of novel facts: quantified facts about sets of kind members (e.g., facts about all or many stups) and generic facts about entire kinds (e.g., facts about zorbs as a kind). Moreover, half of the facts concerned properties that are typically generalizable to an animal kind (e.g., eating fruits and vegetables), and half concerned properties that are typically more idiosyncratic (e.g., getting mud in their hair). We predicted that—because of the hypothesized bias—participants would spontaneously generalize the quantified facts to the corresponding kinds, and would do so more frequently for the facts about generalizable (rather than idiosyncratic) properties. In turn, these generalizations would lead to a higher rate of quantified‐to‐generic memory errors for the generalizable properties. The results of four experiments (N = 449) supported this prediction. Moreover, the same generalizable‐versus‐idiosyncratic difference in memory errors occurred even under cognitive load, which suggests that the hypothesized bias operates unnoticed in the background, requiring few cognitive resources. In sum, this evidence suggests the presence of a powerful bias to draw generalizations about kinds.     

Through the lens of strength: A framework for educating the heart

The work of Chris Peterson and his colleagues provides a context and rationale for creating a new paradigm for character education. While most character education approaches (past and present) have served the purpose of inculcating societal norms and expectations, a positive psychology-based approach seeks to help individuals identify and engage their personal character strengths, thereby promoting well-being. To date, research on character strengths-based classroom interventions has identified positive outcomes related to positive emotion, engagement, relationships, and accomplishment. During the past decade, a number of public and private schools have served as pioneers in this emerging field. This work has contributed to the development of (1) a theoretical framework for infusing strengths-based practices in classrooms and schools and (2) a corresponding body of practices.     

Cognitive aspects of lexical availability

Lexical availability measures the ease with which a word can be generated as a member of a given category. It has been developed by linguistic studies aimed, among other things, at devising a rational basis for selecting words for inclusion in dictionaries. The measure accounts for the number of people who generated a given word as a member of a designated semantic category and the position in which they produce the word. We present an analysis of lexical availability from a cognitive perspective. Data were analysed for Spanish speakers generating words from five semantic categories—clothes, furniture, body parts, animals, and intelligence. Six properties of words were investigated as potential predictors of lexical availability. Predictors were concept familiarity, typicality, imageability, age of acquisition, word frequency, and word length. Categories differed on these variables, and regression analysis found concept familiarity, typicality, and age of acquisition to be significant predictors of lexical availability. The cognitive basis of these findings and the practical consequences of selecting words on the basis of lexical availability are considered.
