Awareness of the Tuskegee syphilis study: impact on offenders' decisions to decline research participation

Ethnic and racial minorities are often under-represented in research. There is considerable speculation that Blacks, in particular, are discouraged from research participation because of researcher improprieties in the U.S. Public Health Service (USPHS) Syphilis Study at Tuskegee (aka the Tuskegee Syphilis Study [TSS]), a 40-year (1932–1972) study in which investigators withheld medical treatment from African-American men infected with syphilis. We debriefed 281 offenders who declined participation in a research study to assess the extent to which knowledge of the TSS impacted their decisions not to enroll. Relatively few (44/281; 15.6%) reported awareness of the TSS. Half (n = 22) of these “aware” individuals could cite factually accurate information about the TSS, and only four individuals indicated that awareness of TSS had “somewhat” influenced their decision to not participate. Findings suggest that the legacy of the TSS played a relatively minor role in these offenders' decisions to decline research participation. Copyright © 2011 John Wiley & Sons, Ltd.     

Eye movements of older and younger readers when reading disappearing text

Older and younger readers read sentences in which target words were masked 40 to 60 ms after fixation onset. Masking only the target word caused more disruption than did masking each word in the sentence, and this effect was stronger for the younger readers than for the older readers. Although older readers had longer eye fixations than did younger readers, the results indicated that the masking effect was comparable for the 2 groups. However, for both groups, how long the eyes remained in place was strongly influenced by the frequency of the fixated word (even though it had been rapidly replaced by the mask and was no longer there when the eyes did move). This is compelling evidence that for both older and younger readers, cognitive/lexical processing has a very strong influence on when the eyes move in reading.     

External Validation of Bifactor Model of ADHD: Explaining Heterogeneity in Psychiatric Comorbidity,Cognitive Control,and Personality Trait Profiles Within DSM-IV ADHD

The current paper provides external validation of the bifactor model of ADHD by examining associations between ADHD latent factor/profile scores and external validation indices. 548 children (321 boys; 302 with ADHD), 6 to 18 years old, recruited from the community participated in a comprehensive diagnostic procedure. Mothers completed the Child Behavior Checklist, Early Adolescent Temperament Questionnaire, and California Q-Sort. Children completed the Stop and Trail-Making Task. Specific inattention was associated with depression/withdrawal, slower cognitive task performance, introversion, agreeableness, and high reactive control; specific hyperactivity-impulsivity was associated with rule-breaking/aggressive behavior, social problems, errors during set-shifting, extraversion, disagreeableness, and low reactive control. It is concluded that the bifactor model provides better explanation of heterogeneity within ADHD than DSM-IV ADHD symptom counts or subtypes.     

A change will do us good: threats diminish typical preferences for male leaders

The current research explores role congruity processes from a new vantage point by investigating how the need for change might shift gender-based leadership preferences. According to role congruity theory, favorability toward leaders results from alignment between what is desired in a leadership role and the characteristics stereotypically ascribed to the leader. Generally speaking, these processes lead to baseline preferences for male over female leaders. In this research, the authors propose that a shift in gender-based leadership preferences will emerge under conditions of threat. Because the psychological experience of threat signals a need for change, individuals will favor candidates who represent new directions in leadership rather than consistency with past directions in leadership. Specifically, they find that threat evokes an implicit preference for change over stability (Experiment 1) and gender stereotypes align women with change but men with stability (Experiments 2a and 2b). Consequently, the typical preference for male leaders is diminished, or even reversed, under threat (Experiments 3 and 4). Moreover, the shift away from typical gender-based leadership preferences occurs especially among individuals who highly legitimize the sociopolitical system (Experiment 4), suggesting that these preference shifts might serve to protect the underlying system.     

Exploring and Promoting the College Attendance and Success of Racial/Ethnic Minority Students

Using consensual qualitative research methodology and being mindful of both challenges and successes, the authors explored diverse students’ experiences with higher education. The authors used semistructured interviews with 7 students with racial/ethnic minority backgrounds to investigate the circumstances under which these students decided to attend college and experienced success. Multiple factors that were reported to contribute to students’ college attendance and success emerged, including individual factors, psychological factors, social factors, and cultural/environmental factors. Utilizando una metodología de investigación cualitativa consensuada y teniendo en cuenta tanto los desafíos como los éxitos, los autores exploraron las experiencias de estudiantes diversos en la educación superior. Los autores usaron entrevistas semiestructuradas con 7 estudiantes de minorías raciales/étnicas para investigar las circunstancias en las que estos estudiantes decidieron cursar estudios universitarios y tuvieron éxito. Surgieron múltiples factores reportados que contribuyeron a la asistencia y al éxito de los estudiantes en la universidad, incluyendo factores individuales, factores psicológicos, factores sociales y factores culturales/del entorno.     

An intervention that increases parental sensitivity in families referred to Child Protective Services also changes toddlers’ parasympathetic regulation

Experiencing maltreatment in early childhood predicts poor parasympathetic regulation, characterized by low baseline parasympathetic activity and strong withdrawal of parasympathetic influence in response to tasks. The Promoting First Relationships^® (PFR) program improves parental sensitivity toward young children in families identified as maltreating. Using a subsample from a randomized control trial, we examined whether parental participation in PFR had lasting effects on toddlers’ parasympathetic regulation, as measured by respiratory sinus arrhythmia (RSA), relative to a resource and referral control condition. In addition, we examined whether parental sensitive and responsive behavior mediated or moderated associations between parent treatment group and children's RSA. More than 6 months after completing treatment, 29 families in the PFR condition and 30 families in the control condition were visited at home, and toddlers’ RSA was assessed at baseline and during five moderately challenging tasks. Groups did not differ in baseline RSA, but differed in RSA reactivity to the tasks. Across tasks, toddlers of parents in the control condition manifested significantly larger RSA decreases than toddlers of parents in the PFR condition. Parental behavior showed divergent associations with RSA change for toddlers of parents in the PFR versus control condition, with PFR treatment predicting RSA change ranging from small decreases to increases in toddlers of parents who showed the most sensitive, responsive behavior in the 6 months following treatment. This preliminary study showed that the same intervention that improved parenting also improved toddlers’ parasympathetic regulation in response to everyday activities, warranting further experimental investigation.     

Comparison-level preferences after performance: is downward comparison theory still useful?

Although often credited with prompting a paradigm shift in social comparison theory, T. A. Wills's (1981) downward comparison (DC) theory has received some criticism recently. In particular, several recent studies have failed to find support for T. A. Wills's (1981) contention that threat and accompanying negative affect lead to a desire for DC. These apparent failures have led some investigators to question basic principles of the theory. To resolve this controversy, 5 studies were conducted examining preferred comparison level (PCL) after performance; 4 of the studies also assessed change in this preference. Results supported DC theory, but with modifications. Specifically, individuals who performed poorly lowered their PCLs. Under some circumstances, this "downward shift" included an increased interest in "true" DC--comparing with worse-off others. A reconciliation of these results with those of previous studies is offered.     

Prejudice from thin air: The effect of emotion on automatic intergroup attitudes

Two experiments provide initial evidence that specific emotional states are capable of creating automatic prejudice toward outgroups. Specifically, we propose that anger should influence automatic evaluations of outgroups because of its functional relevance to intergroup conflict and competition, whereas other negative emotions less relevant to intergroup relations (e.g., sadness) should not. In both experiments, after minimal ingroups and outgroups were created, participants were induced to experience anger, sadness, or a neutral state. Automatic attitudes toward the in- and outgroups were then assessed using an evaluative priming measure (Experiment 1) and the Implicit Association Test (Experiment 2). As predicted, results showed that anger created automatic prejudice toward the outgroup, whereas sadness and neutrality resulted in no automatic intergroup bias. The implications of these findings for emotion-induced biases in implicit intergroup cognition in particular, and in social cognition in general, are considered.     

Hemispheric performance in object-based attention

The goal of the present study was to investigate whether object-based attention effects differ across the cerebral hemispheres. Previous research has suggested that object-based attention is preferentially lateralized to the left hemisphere (Egly, Driver, & Rafal, 1994; Egly, Rafal, Driver, & Starrveveld, 1994). However, work by Vecera (1994) has suggested that these previous studies may have failed to obtain a pure measure of object-based attention. The present study applied modified versions of Duncan's (1984) seminal object-based attention paradigm. Subjects were typically presented with one target object to a single visual field (one-object display), two target objects to the same visual field (two-object unilateral display), or two target objects to different visual fields (two-object bilateral display). In all three experiments, response accuracy was higher for the one-object displays than for the two-object displays. Most important, this object-based cost was especially severe when selection of two target elements was isolated to the right visual field (left hemisphere). We confirmed that this effect was specific to object-based attention in three different ways: Experiment 1 manipulated stimulus distance, as recommended by Vecera; Experiment 2 ensured that target selection was based on nonspatial attributes; and Experiment 3 used overlapping displays, as in Duncan (1984). Collectively, the data are in accord with previous conclusions that object-based attention is a specialized form of orienting subserved by lateralized cortical brain mechanisms. However, contrary to previous research, it appears that it is the right hemisphere, and not the left hemisphere, that is preferentially biased for committing object-based attention to elements in the visual environment.
