Filtering by movement in visual search.

Search for a target defined by a conjunction of movement and form (e.g., an X moving up in a display of intermingled Os moving up and stationary Xs) is parallel. This result is also found if (a) the moving Os and target X move in unpredictable directions so that the moving stimuli do not form a clear perceptual group or (b) the nontarget Xs also move but in a known, different direction from the Os and target X. In contrast, search is slow and serial if the target may be unpredictably among either moving or stationary stimuli. These results suggest that a component of the visual system operates as a movement filter that can direct attention to stimuli with a common movement characteristic. The filtering cue can be moving (vs. stationary), or movement in 1 particular direction. The results do not support the view that attention can only be directed to groups defined by common fate.     

Racism in the Hands of an Angry God: How Image of God Impacts Cultural Racism in Relation to Police Treatment of African Americans

Previous research suggests an angry God image is a narrative schema predicting support for more punitive forms of criminal justice. However, this research has not explored the possibility that racialization may impact one's God image. We perform logistic regression on Wave V of the Baylor Religion Survey to examine the correlation between an angry God image and the belief that police shoot Blacks more often because Blacks are more violent than Whites (a context-specific form of cultural racism). Engaging critical insights from intersectionality theory, we also interact angry God image with both racialized identity and racialized religious tradition. Results suggest that the angry God schema is associated with this form of cultural racism for White people generally as well as White Evangelicals, yet for Black Protestants, belief in an angry God is associated with resistance against this type of cultural racism.     

Verbal memory abilities of children with brain tumors.

Several critical neuroanatomical structures and pathways for memory performance are located in the third ventricle region. This led us to predict that verbal memory abilities would be more impaired in children treated for third ventricle tumors compared to those treated for cerebellar tumors. Archival data was obtained from 24 pediatric patients with third ventricle region tumors and 18 pediatric patients with cerebellar tumors. Neuroradiological verifications of tumor involvement and hydrocephalus severity (i.e., Evans Index) on preoperative scans and MRIs proximal to the time of the neuropsychological evaluation were conducted. The potential confounds of hydrocephalus severity, seizure medication, age, radiation treatment, and chemotherapy were addressed. Verbal IQ was comparable between tumor groups and in the Average range. The third ventricle region group performed significantly worse on list learning and delayed list recall compared to the cerebellar group. Their mean performance was in the clinically impaired range on both trials. The third ventricle region tumor group performed better than the cerebellar tumor group on Digit Span, a basic repetition, attention span task. These findings support the hypothesis that pediatric patients with third ventricle region brain tumors are more likely to be impaired on verbal recall tasks compared to pediatric patients with cerebellar brain tumors. In contrast, patients who were treated for cerebellar tumors were more impaired on the basic repetition, attention span task compared to patients who were treated for third ventricle tumors. Future studies should examine the specific neuroanatomical structures and pathways that are damaged and may influence differential cognitive impairments in children.     

LAW NECESSITARIANISM AND THE IMPORTANCE OF BEING INTUITIVE

The counter-intuitive implications of law necessitarianism pose a far more serious threat than its proponents recognize. Law necessitarians are committed to scientific essentialism, the thesis that there are metaphysically necessary truths which can be known only a posteriori. The most frequently cited arguments for this position rely on modal intuitions. Rejection of intuition thus threatens to undermine it. I consider ways in which law necessitarians might try to defend scientific essentialism without invoking intuition. I then consider ways in which law necessitarians who accept the general reliability of intuition might try to explain away the intuitions which conflict with their theory.     

The Police Officer Tacit Knowledge Inventory (POTKI): Towards Determining Underlying Structure and Applicability as a Recruit Screening Tool

Summary The purpose of this research was to examine the potential application of the police officer tacit knowledge inventory (POTKI) as a police recruit screening tool. The POTKI is a situational judgment test and consists of knowledge gained on the job by experienced officers that is thought to be important for problem‐solving. In the present study, four police agencies from a western US state administered the POTKI along with other screening measures to police applicants. Performance of the novice recruits was subsequently rated by their supervisors using the measure of professional expertise (MOE). Principal component analysis, multiple regression analysis, and multivariate analysis of variance were conducted on the POTKI response options. POTKI response options were found to be predictive of supervisor MOE ratings. Principal component analysis results identified intrapersonal tacit knowledge components that predicted MOE metacognitive, skill, and social recognition supervisor ratings and distinguished novice from expert police officers.Copyright © 2017 John Wiley & Sons, Ltd.     

Does Repeated Exposure to Popular Media Strengthen Moral Intuitions?: Exploratory Evidence Regarding Consistent and Conflicted Moral Content

Previous studies have indicated that media consumption may influence moral intuition sensitivity. The present exploratory studies sought to expand on these findings by employing a three-phase, longitudinal experiment conducted over nine weeks, where participants were exposed to two genres of films (romance, action) mixed in various ratios (high = 100% romance, medium = 60% romance, low = 20% romance, none = 0% romance). Findings from the initial study indicate that repeated exposure to romantic films led to increases in sensitivity for four of the five moral intuitions (i.e., care, fairness, authority, purity); at the same time, any exposure to action films seemed to erode these changes. A follow-up post-hoc content analysis sought to confirm these findings and test an operationalization of “moral conditioning.” We discuss the results in regards to media entertainment theory and research, and the societal implications of the role of media entertainment to reinforce standards of moral judgment.     

Short-term and long-term attentional biases to frequently encountered target features

It has long been known that frequently occurring targets are attended better than infrequent ones in visual search. But does this frequency-based attentional prioritization reflect momentary or durable changes in attention? Here we observed both short-term and long-term attentional biases for visual features as a function of different types of statistical associations between the targets, distractors, and features. Participants searched for a target, a line oriented horizontally or vertically among diagonal distractors, and reported its length. In one set of experiments we manipulated the target’s color probability: Targets were more often in Color 1 than in Color 2. The distractors were in other colors. Participants found Color 1 targets more quickly than Color 2 targets, but this preference disappeared immediately when the target’s color became random in the subsequent testing phase. In the other set of experiments, we manipulated the diagnostic values of the two colors: Color 1 was more often a target than a distractor; Color 2 was more often a distractor than a target. Participants found Color 1 targets more quickly than Color 2 targets. Importantly, and in contrast to the first set of experiments, the featural preference was sustained in the testing phase. These results suggest that short-term and long-term attentional biases are products of different statistical information. Finding a target momentarily activates its features, inducing short-term repetition priming. Long-term changes in attention, on the other hand, may rely on learning diagnostic features of the targets.
