RESISTANCE TO CHANGE AND FREQUENCY OF RESPONSE‐DEPENDENT STIMULI UNCORRELATED WITH REINFORCEMENT

Stimuli uncorrelated with reinforcement have been shown to enhance response rates and resistance to disruption; however, the effects of different rates of stimulus presentations have not been assessed. In two experiments, we assessed the effects of adding different rates of response‐dependent brief stimuli uncorrelated with primary reinforcement on relative response rates and resistance to change. In both experiments, pigeons responded on variable‐interval 60‐s schedules of food reinforcement in two components of a multiple schedule, and brief response‐dependent keylight‐color changes were added to one or both components. Although relative response rates were not systematically affected in either experiment, relative resistance to presession feeding and extinction were. In Experiment 1, adding stimuli on a variable‐interval schedule to one component of a multiple schedule either at a low rate (1 per min) for one group or at a high rate (4 per min) for another group similarly increased resistance to disruption in the components with added stimuli. When high and low rates of stimuli were presented across components (i.e., within subjects) in Experiment 2, however, relative resistance to disruption was greater in the component presenting stimuli at a lower rate. These results suggest that stimuli uncorrelated with food reinforcement do not strengthen responding in the same way as primary reinforcers.     

Measuring preschool cognitive growth while it's still happening: The Learning Express

Educators need accurate assessments of preschool cognitive growth to guide curriculum design, evaluation, and timely modification of their instructional programs. But available tests do not provide content breadth or growth sensitivity over brief intervals. This article details evidence for a multiform, multiscale test criterion-referenced to national standards for alphabet knowledge, vocabulary, listening comprehension and mathematics, developed in field trials with 3433 3–5¹/₂-year-old Head Start children. The test enables repeated assessments (20–30 min per time point) over a school year. Each subscale is calibrated to yield scaled scores based on item response theory and Bayesian estimation of ability. Multilevel modeling shows that nearly all score variation is associated with child performance rather than examiner performance and individual growth-curve modeling demonstrates the high sensitivity of scores to child growth, controlled for age, sex, prior schooling, and language and special needs status.     

The Obama effect: Decreasing implicit prejudice and stereotyping

This project explores the impact of Barack Obama’s presidential campaign and the resulting high levels of exposure to a positive, counter-stereotypic Black exemplar, on prejudice and stereotyping among non-Black participants. We found dramatically decreased levels of implicit anti-Black prejudice and stereotyping as compared with bias observed previously at the same institutions and in the literature. Providing some insight why the bias was reduced, Study 1 demonstrated that participants had positive Black exemplars come to mind or anticipated that other people have positive exemplars come to mind when they thought of Black people and this was associated with low levels of racial prejudice. Our second study revealed that participants who had qualities strongly associated with Obama as a political figure (e.g., president) activated when they were primed with “Black” had lower levels of implicit prejudice. These findings indicate that the extensive exposure to Obama resulted in a drop in implicit bias.     

A longitudinal investigation of maternal touching across the first 6 months of life: Age and context effects

The types of touch used by 12 mothers with their 1-, 3- and 5.5-month-old infants were examined longitudinally during two different interaction contexts lasting 5 min each. Changes in maternal touching as a function of infants’ age and interaction context were revealed.     

Promoting aggression and violence at Abu Ghraib: The U.S. military's transformation of ordinary people into torturers

The torture of detainees at Abu Ghraib has been characterized as an isolated incident and blamed on a few “bad apples.” However, as similar reports of war crimes throughout Iraq continue to surface, it seems increasingly apparent that in the anxious post-9/11 context, the low-level agents who carried out such violence were designed to function in this way. This paper suggests that the U.S. military transformed ordinary soldiers into the cruel and ruthless guards at Abu Ghraib through the use of basic recruitment and training strategies, general authorizations for increased aggression and violence after 9/11, specific authorizations for more aggressive interrogations, a range of pressures and protections, and the dehumanization of prisoners. While the legitimate needs of an effective Army must be preserved, this paper offers several specific ways we might reform the U.S. military and prevent such abuses in the future.     

The medium can influence the message: Print-based versus digital reading influences how people process different types of written information

While electronic reading devices are extremely popular, research is equivocal regarding their benefits for outcomes such as reader comprehension. Integrating literatures on reading medium comparisons and matching effects in persuasion, this research tested whether comprehension is maximized when the content of the material (e.g., whether it is traditional vs. modern) matches the medium (e.g., reading from a traditional book vs. digital e-reader). In Study 1, participants read a traditional- or modern-themed short story from either a book or an e-reader. Story comprehension was greater when participants read from the printed medium compared to the e-reader, an effect that was marginally moderated by story content, consistent with a matching effect. In Study 2, participants read a persuasive message that emphasized either a traditional versus modern solution to improving health in either a magazine format or on an iPad. Message comprehension was marginally greater among participants who read their message in a printed format. Participants’ interest in weight loss showed evidence of a matching effect – participants were more interested in losing weight when a modern solution to obesity article was presented on an iPad compared to a printed format. The results are applied to the study of reading and attitude change.     

The relationship between intercultural abilities and cultural identity styles: A longitudinal cross-lagged analysis

Hybrid and alternating identity styles are dynamic strategies that members of immigrant and ethnic minority groups use to maintain multiple cultural identities. Although research shows that the two strategies predict different outcomes for cultural identity development and psychological well-being, less is known about their antecedents. The present study investigated the temporal relationship between intercultural abilities (i.e. intercultural effectiveness) and the activation of hybrid and alternating identity styles in a community sample of Filipino and Indian New Zealanders. Cross-lagged analysis indicated that intercultural abilities positively predicted the hybrid identity style and negatively predicted the alternating identity style. Cultural identity styles were not predictive of intercultural abilities over time. Multigroup analysis indicated equivalence of regression paths across ethnic groups. Findings suggest that intercultural abilities function as an antecedent of cultural identity styles.     

What they think of us: Meta-beliefs and solidarity-based collective action among the advantaged

Collective action researchers have recently started investigating solidarity-based collective action by advantaged groups. This literature, however, has overlooked intergroup meta-beliefs (MBs, i.e., beliefs about the outgroup's beliefs), which we argue are crucial, since solidarity inherently involves protesting for the outgroup. In the context of racial inequality in the U.S., we focused on three MBs White Americans could hold: responsibility, inactivity, and allyship. In two studies (N_total = 648), we found that inactive and responsible MBs predicted higher collective action tendencies among low White identifiers via guilt and obligation to act. Conversely, we found that both predicted lower collective action tendencies among high White identifiers, via perceived unfairness. Finally, we found that ally MB was positively associated with collective action tendencies, regardless of identification. We highlight the importance of the meta-perspective in understanding solidarity-based collective action, and discuss conceptual and practical implications of these findings.     

From desire to development? A multi-sample,idiographic examination of volitional personality change

Using an idiographic-nomothetic methodology, we assessed individuals’ ability to change their personality traits without therapeutic or experimental involvement. Participants from internet and college populations completed trait measures and reported current personality change desires. Self-reported traits as well as perceptions of trait change were collected after 1-year (Internet) and 6-months (College). In large part, volitional personality change desires did not predict actual change. When desires did predict change, (a) desired increases in Extraversion, Agreeableness and Conscientiousness corresponded with decreases in corresponding traits, (b) participants perceived more change than actually occurred, and (c) decreases in Emotional Stability predicted perceptions of personality change. Results illustrate the difficulty in purposefully changing one’s traits when left to one’s own devices.
