Do emotion-induced blindness and the attentional blink share underlying mechanisms? An event-related potential study of emotionally-arousing words

When two targets are presented within approximately 500 ms of each other in the context of rapid serial visual presentation (RSVP), participants’ ability to report the second target is reduced compared to when the targets are presented further apart in time. This phenomenon is known as the attentional blink (AB). The AB is increased in magnitude when the first target is emotionally arousing. Emotionally arousing stimuli can also capture attention and create an AB-like effect even when these stimuli are presented as to-be-ignored distractor items in a single-target RSVP task. This phenomenon is known as emotion-induced blindness (EIB). The phenomenological similarity in the behavioral results associated with the AB with an emotional T1 and EIB suggest that these effects may result from similar underlying mechanisms – a hypothesis that we tested using event-related electrical brain potentials (ERPs). Behavioral results replicated those reported previously, demonstrating an enhanced AB following an emotionally arousing target and a clear EIB effect. In both paradigms highly arousing taboo/sexual words resulted in an increased early posterior negativity (EPN) component that has been suggested to represent early semantic activation and selection for further processing in working memory. In both paradigms taboo/sexual words also produced an increased late positive potential (LPP) component that has been suggested to represent consolidation of a stimulus in working memory. Therefore, ERP results provide evidence that the EIB and emotion-enhanced AB effects share a common underlying mechanism.     

The equivalence of contingency structure for intuitive covariation judgments about height, weight, and body fat

In a complete between-subjects design, 576 respondents judged covariations of problems framed around height, weight, and body fat. A verbal measure was used, consisting of propositional statements representing relationships between two of the variables, as well as two types of response options: true or false, and a 7-point, bipolar, Likert-type scale. Consistent with previous findings, weight and body fat were unambiguously judged as if positively correlated; there were indications of a perceived negative correlation of height and body fat; and there was no evidence that participants regarded height and weight as positively correlated. Furthermore, there was no reliable evidence in support of framing effects. However, there were indications of influence for conditional format. These findings are discussed relative to previous and ongoing research efforts, and it is concluded that it may be inappropriate to regard variations in conditional format as parallel items. Measures involving all possible variations are considered fundamentally unbiased and consistent with I. Ajzen's (1988) principle of aggregation.     

Changing Race Boundary Perception by Reading Narrative Fiction

Participants read a story about a counterstereotypical Muslim woman and were then asked to determine the race of ambiguous-race Arab-Caucasian faces. Compared to a content-matched control condition, participants who read the narrative exhibited lower categorical race bias by making fewer categorical race judgments and perceiving greater genetic overlap between Arabs and Caucasians (Experiment 1). In Experiment 2, participants determined the race of ambiguous-race Arab-Caucasian faces depicting low and moderate anger. Emotion-related perceptual race bias was observed in the control conditions where higher intensity anger expressions led participants to disproportionately categorize faces as Arab. This bias was eliminated in the narrative condition.     

Gender,Status, and Tax Offenses

Current literature on tax evasion finds that compared to women, men are more likely to engage in tax evasion. This study examines how expectation states theory helps explain this gender difference by investigating the relationship between status and compliance to authority using a secondary analysis of ICPSR data on the Monitoring of Federal Criminal Sentences. We hypothesize that the effect of gender on the odds of being convicted for a tax offense compared to any other white collar crime will decrease when controlling for other diffuse status characteristics. Results from a series of multivariate regression models support this hypothesis.     

Relationships between cognition and literacy in children with attention-deficit/hyperactivity disorder: A systematic review and meta-analysis

Evidence suggests that cognitive and literacy difficulties are common for children with Attention-Deficit/Hyperactivity Disorder (ADHD). The current systematic review and meta-analysis investigated the relationship between cognition and literacy in children with ADHD. Ten thousand and thirty-eight articles were screened against the inclusion criteria and six eligible studies were retained for final review. Where two or more studies used comparable measures of cognition and literacy, a meta-analysis of the relationship between these measures was undertaken. A narrative synthesis of all included studies was also completed. There were medium effect sizes between working memory and aspects of reading, and small effect sizes between processing speed and reading. Inhibition and attention had differential relationships with aspects of literacy with varying effect sizes. This systematic review demonstrates differential relationships between aspects of literacy and cognition in children with ADHD. Further examination of these relationships is warranted to support intervention development.     

Victim Ambiguity: Bystander Intervention and Sexual Assault in the College Drinking Scene

Alcohol-related sexual assault is the most common form of sexual victimization on college campuses. Bystander intervention has been suggested as effective in preventing sexual assault, but its usefulness in sexual assaults that involve alcohol in particular has not yet been examined. The current study draws from intensive interviews with 30 undergraduates at a large Midwestern university to understand how students’ perceptions about sexual victimization and alcohol use affect their bystander behavior. Findings suggest that in alcohol-involved situations, the ambiguity of whether the woman is at risk and her perceived worthiness are significant barriers to intervention. Policy implications are discussed.     

Concurrent and Predictive Validity of Reading Retell as a Brief Measure of Reading Comprehension for Narrative Text

Concurrent and predictive validity between the Retell Reading Rubric (RRR), Oral Reading Fluency (ORF), an adaptation of the DIBELS Retell Fluency (RTF-A), and a state assessment emphasizing reading comprehension were examined across students in grades 3 and 5. Results showed the RRR to have moderate and statistically significant relationships to the ORF, RTF-A, and the state assessment for grade 3, but weaker relationships for grade 5. For grade 3, the RRR accounted for a small significant proportion of variance beyond ORF in predicting outcomes on the state assessment for third grade, but no statistically significant contribution for grade 5.
