The perceived ethnic discrimination questionnaire--community version: validation in a multiethnic Asian sample

This study evaluated the validity and reliability of the Perceived Ethnic Discrimination Questionnaire-Community Version (PEDQ-CV) Lifetime Exposure scale in a multiethnic Asian sample (N = 509). The 34-item scale measures perceived interpersonal racial/ethnic discrimination and includes four subscales assessing different types of discrimination: Social Exclusion, Stigmatization, Discrimination at Work/School, and Threat/Aggression. The Lifetime Exposure scale demonstrated excellent reliability across the full group and in all major subgroups. Subscales displayed good reliability across the full group and moderate-to-good reliability in each subgroup. The Lifetime Exposure scale was significantly correlated with the depression and anxiety subscales of the SCL-90-R, providing preliminary evidence of construct validity. The data suggest the Lifetime Exposure scale, previously validated in Black and Latino adults, is also appropriate for use with Asian samples, and can be used to examine both within-group and between-groups differences in discrimination.     

Feasibility of telephone-based cognitive behavioral therapy targeting major depression among urban dwelling African-American people with co-occurring HIV

Given the burden of depression among those with HIV, and the impact of HIV on urban minority communities there is an urgent need to assess innovative treatment interventions that not only treat depression but do so in a way that allows for increased access to mental health care. This single site, uncontrolled, pilot study sought to determine the feasibility and depression outcomes of an 11-session telephone-based cognitive behavioral therapy intervention delivered over 14 weeks targeting low-income, urban-dwelling, HIV-infected African-American people with major depression. The diagnosis of major depression was made using the Mini International Neuropsychiatric Interview. The primary outcome was the Hamilton Depression Rating Scale (HAM-D) and the secondary outcome was the Quick Inventory of Depression Symptomatology-Self Report (QIDS-SR). Feasibility and satisfaction were also assessed. Assessments occurred at baseline, midpoint and at study conclusion (14 weeks). Fifteen people were screened for the study. Six HIV-infected, low-income, African-American people individuals (five females and one male) were eligible and participated in the study. All patients finished the study. On average, participants completed nine sessions. The sessions lasted for an average of 48 min (SD = 11.5). Compared to mean HAM-D score at baseline (HAM-D = 22.8 (SD = 3.1), the mean HAM-D score was significantly reduced at study conclusion (HAM-D = 9.8 (SD = 7.4); (t (5) = 4.6, p = 0.006); (Cohen d = 1.9)). Compared to the mean QIDS-SR score at baseline (QIDS-SR = 15.5 (SD = 4.2) the mean QIDS score was significantly reduced at study conclusion (QIDS = 7.0 (SD = 5.4);(t (5) = 3.2, p = 0.02); (Cohen d = 1.3)).The mean satisfaction scores across all participants at post-treatment was 5.7 (SD = 0.3) with of a maximum score of 6. Telephone-based CBT can be delivered to low-income, urban-dwelling ethnic minority HIV-infected people resulting in significant reductions in depression symptoms with high satisfaction. The efficacy of this intervention will be assessed in a planned randomized control trial.     

The role of socio-communicative rearing environments in the development of social and physical cognition in apes

The cultural intelligence hypothesis (CIH) claims that humans’ advanced cognition is a direct result of human culture and that children are uniquely specialized to absorb and utilize this cultural experience ( Tomasello, 2000 ). Comparative data demonstrating that 2.5‐year‐old human children outperform apes on measures of social cognition but not on measures of physical cognition support this claim ( Herrmann et al., 2007 ). However, the previous study failed to control for rearing when comparing these two species. Specifically, the human children were raised in a human culture whereas the apes were raised in standard sanctuary settings. To further explore the CIH, here we compared the performance on multiple measures of social and physical cognition in a group of standard reared apes raised in conditions typical of zoo and biomedical laboratory settings to that of apes reared in an enculturated socio‐communicatively rich environment. Overall, the enculturated apes significantly outperformed their standard reared counterparts on the cognitive tasks and this was particularly true for measures of communication. Furthermore, the performance of the enculturated apes was very similar to previously reported data from 2.5‐year‐old children. We conclude that apes who are reared in a human‐like socio‐communicatively rich environment develop superior communicative abilities compared to apes reared in standard laboratory settings, which supports some assumptions of the cultural intelligence hypothesis.     

Controlling attention to gaze and arrows in childhood: an fMRI study of typical development and Autism Spectrum Disorders

Functional magnetic resonance imaging was used to examine functional anatomy of attention to social (eye gaze) and nonsocial (arrow) communicative stimuli in late childhood and in a disorder defined by atypical processing of social stimuli, Autism Spectrum Disorders (ASD). Children responded to a target word ('LEFT'/'RIGHT') in the context of a distracting arrow or averted gaze pointing in a direction that was congruent, incongruent, or neutral (bar without arrowheads, central gaze) relative to the target word. Despite being irrelevant to the target task, both arrow and averted gaze facilitated responses (Congruent vs. Neutral trials) to the same extent in the two groups and led to interference (Incongruent vs. Congruent trials), which was greater from arrows in ASD than control children. In the brain, interaction between group and distracter-domain was observed in frontal-temporal regions during facilitation and frontal-striatal regions during interference. During facilitation, regions associated with attention to gaze in control children (left superior temporal sulcus, premotor) were associated with attention to arrows in ASD children; gaze was associated with medial temporal involvement in ASD children. During interference, regions associated with arrows in control children (anterior cingulate, right caudate) were activated in response to gaze in ASD children; further, left dorsolateral prefrontal cortex, a region not observed in control children, was activated during gaze-interference in ASD children. Thus, functional anatomy was atypical in ASD children during spontaneous processing of social and nonsocial communicative cues.     

Are positive emotions just as "positive" across cultures?

Whereas positive emotions and feeling unequivocally good may be at the heart of well-being among Westerners, positive emotions often carry negative associations within many Asian cultures. Based on a review of East-West cultural differences in dialectical emotions, or co-occurring positive and negative feelings, we predicted culture to influence the association between positive emotions and depression, but not the association between negative emotions and depression. As predicted, in a survey of over 600 European-, immigrant Asian-, and Asian American college students, positive emotions were associated with depression symptoms among European Americans and Asian Americans, but not immigrant Asians. Negative emotions were associated with depression symptoms among all three groups. We also found initial evidence that acculturation (i.e., nativity) may influence the role of positive emotions in depression: Asian Americans fell "in between" the two other groups. These findings suggest the importance of studying the role of culture in positive emotions and in positive psychology. The use of interventions based on promoting positive emotions in clinical psychology among Asian clients is briefly discussed.     

Electrophysiological responses to evaluative priming: the LPP is sensitive to incongruity

Previous studies examining event-related potentials and evaluative priming have been mixed; some find evidence that evaluative priming influences the N400, whereas others find evidence that it affects the late positive potential (LPP). Three experiments were conducted using either affective pictures (Experiments 1 and 2) or words (Experiment 3) in a sequential evaluative priming paradigm. In line with previous behavioral findings, participants responded slower to targets that were evaluatively incongruent with the preceding prime (e.g., negative preceded by positive) compared to evaluatively congruent targets (e.g., negative preceded by negative). In all three studies, the LPP was larger to evaluatively incongruent targets compared to evaluatively congruent ones, and there was no evidence that evaluative incongruity influenced the N400 component. Thus, the present results provide additional support for the notion that evaluative priming influences the LPP and not the N400. We discuss possible reasons for the inconsistent findings in prior research and the theoretical implications of the findings for both evaluative and semantic priming.     

Cognitive and metacognitive activity in mathematical problem solving: prefrontal and parietal patterns

Students were taught an algorithm for solving a new class of mathematical problems. Occasionally in the sequence of problems, they encountered exception problems that required that they extend the algorithm. Regular and exception problems were associated with different patterns of brain activation. Some regions showed a Cognitive pattern of being active only until the problem was solved and no difference between regular or exception problems. Other regions showed a Metacognitive pattern of greater activity for exception problems and activity that extended into the post-solution period, particularly when an error was made. The Cognitive regions included some of parietal and prefrontal regions associated with the triple-code theory of (Dehaene, S., Piazza, M., Pinel, P., & Cohen, L. (2003). Three parietal circuits for number processing. Cognitive Neuropsychology, 20, 487–506) and associated with algebra equation solving in the ACT-R theory (Anderson, J. R. (2005). Human symbol manipulation within an 911 integrated cognitive architecture. Cognitive science, 29, 313–342. Metacognitive regions included the superior prefrontal gyrus, the angular gyrus of the triple-code theory, and frontopolar regions.     

Expectation and temperament moderate amygdala and dorsal anterior cingulate cortex responses to fear faces

A chronic tendency to avoid novelty is often the result of a temperamental bias called inhibited temperament, and is associated with increased risk for anxiety disorders. Neuroimaging studies have demonstrated that an inhibited temperament is associated with increased amygdalar blood-oxygenation-level-dependent (BOLD) response to unfamiliar faces that were not expected; however, the effects of variations in expectancy remain unknown. Using functional magnetic resonance imaging (fMRI), we studied BOLD response to infrequently encountered fear faces that were either expected or not expected in 42 adults with an inhibited or an uninhibited temperament. Individuals with an inhibited temperament had greater amygdala, but less dorsal anterior cingulate cortex (dACC), BOLD response when the stimuli were expected. In contrast, those with an uninhibited temperament had a smaller amygdala but larger dorsal anterior cingulate cortex BOLD response when expecting to see fear faces. These findings demonstrate temperament differences in expectancy effects and provide preliminary evidence for the dACC as a neural substrate mediating differences in inhibited temperament. Enhanced amygdala sensitivity coupled with weak inhibitory control from the dACC may form a neural circuit mediating behaviors characteristic of inhibited temperament and risk for anxiety disorders.
