Target-to-target repetition cost and location negative priming are dissociable: evidence for different mechanisms

In a location-selection task, the repetition of a prior distractor location as the target location would slow down the response. This effect is termed the location negative priming (NP) effect. Recently, it has been demonstrated that repetition of a prior target location as the current target location would also slow down response. Because such target-to-target repetition cost is similar to the phenomenon of inhibition of return (IOR), the possibility of a common mechanism underlying target-to-target repetition cost, location NP, and IOR has been proposed. The current study evaluated this hypothesis by combining a spatial-cuing task with a location NP task. The results of three experiments demonstrated that although IOR interacted with target-to-target repetition cost, there was no interaction between IOR and location NP. These findings suggest that target-to-target repetition cost is more likely to share a common mechanism with IOR, and target-to-target repetition cost and location NP should be attributed to different processes.     

Genuineness matters: Using cheaper, generic products induces detrimental self-evaluations

People purchase generic products in an attempt to reduce costs. In this article, we showed that using generic products primes a devalued sense of self-worth manifested by increasing the likelihood of lower self-evaluations. In Experiment 1, participants were randomly assigned to use generic or genuine computer peripherals to make personal vitas for an upcoming recruitment orientation. Those using generic peripherals expected to earn a lower salary per month than the participants using original peripherals. Experiment 2 showed that the effect of using generic accessories extended to the context of interpersonal relations, influencing how participants thought others judged them in a get-acquainted task. Experiment 2 further demonstrated that the feelings of devalued self-worth primed by using compatible mobile-phone batteries mediated the effect of generic products on self-estimated attractiveness. Together these findings suggested that, even incidentally used cheaper, generic products may prime people for a lowered sense of self-worth, which would then produce disadvantageous self-evaluations.     

Intergenerational cultural dissonance in parent-adolescent relationships among Chinese and European Americans

Generational cultural gaps (assessed as the mismatch between adolescents' ideals and perceptions of the parent-adolescent relationship) were investigated among Chinese youth with immigrant parents and their European American counterparts who have been in the United States for generations and assumingly do not have intergenerational cultural gaps. The authors of the study examined the associations of such generational gaps with adolescents' behavioral problems and whether youth's appreciation of Chinese parent-adolescent relationships (parental devotion, sacrifice, thoughtfulness, and guan) described by the notion of qin would moderate the relationship between discrepancies and youth's adjustment. A total of 634 high school students (M = 15.97 years; 95 and 154 first- and second-generation Chinese American respectively, and 385 European Americans) completed measures of parental warmth, parent-adolescent open communication, qin, and psychological adjustment. The U.S.-born Chinese American adolescents' ideals exceeded perceptions of parents' warmth and open communication to a greater degree than it did for European American adolescents (ps < 0.05). Such discrepancies in parental warmth were related to greater internalizing symptoms for second-generation Chinese American youth than for their European American peers. In addition, for second-generation Chinese, their perceptions of qin, particularly parents' devotion and sacrifice, had stronger moderating effects, diminishing the associations between generational cultural gaps and youth's behavioral problems compared with those of European American and first-generation Chinese youth. Parental thoughtfulness also played a similar beneficial role, but did so for all youth.     

Race/ethnicity, color-blind racial attitudes, and multicultural counseling competence: the moderating effects of multicultural counseling training

Increasing trainees' multicultural counseling competence (MCC) has been a hot topic in counseling. Scholars have identified predictors (e.g., race/ethnicity, color-blindness) of MCC, and educators provide multicultural training for trainees. Using a sample of 370 psychology trainees, this study examined whether multicultural training (a) moderated racial/ethnic differences on MCC and (b) changed the relationship between color-blindness and MCC. Results indicated a significant interaction effect of race/ethnicity (i.e., White vs. ethnic minority) and multicultural training on multicultural awareness, but not on multicultural knowledge. Specifically, at lower levels of training, racial/ethnic minority trainees had significantly higher multicultural awareness than their White counterparts; at higher levels of training, no significant difference was found. Described differently, more training significantly enhanced Whites' multicultural awareness, but did not enhance racial/ethnic minority trainees' awareness. Additionally, there was a significant interaction effect of color-blindness and multicultural training on multicultural knowledge, but not on multicultural awareness. The association between color-blindness and multicultural knowledge was stronger at higher levels of multicultural training than at lower levels of training. Alternatively, the effect of training on enhancing knowledge was stronger for those with lower color-blindness than for those with higher color-blindness.

Multiculturally Sensitive Mental Health Scale (MSMHS): development, factor analysis, reliability, and validity

Effectively and efficiently diagnosing African Americans' mental health has been a chronically unresolved challenge. To meet this challenge we developed a tool to better understand African Americans' mental health: the Multiculturally Sensitive Mental Health Scale (MSMHS). Three studies reporting the development and initial validation of the MSMHS were conducted with African American student samples. First, an exploratory factor analysis of an initial item pool yielded 5 factors assessing subscales of perceived racism, depression, well-being, anxiety, and suicidal thoughts. Second, a confirmatory factor analysis supported the MSMHS's 5-dimensional factor structure. Third, test-retest reliability, internal consistency, and validity coefficients supported the viability, use, and potential for continued development of this new instrument. Implications for theory and research on multicultural mental health scales are discussed.     

Racial/Ethnic Identity,Gender‐Role Attitudes,and Multicultural Counseling Competence: The Role of Multicultural Counseling Training

Researchers and practitioners have been pursuing how to enhance counselors' multicultural counseling competencies (MCC). With a sample of 460 counselors, the author examined whether multicultural training changed the relationship between (a) racial/ethnic identity and MCC and (b) gender‐role attitudes and MCC. The author found significant interaction effects of (a) racial/ethnic identity and multicultural training and (b) gender‐role attitudes and multicultural training on multicultural knowledge but not on multicultural awareness.     

The Concerns about Counseling Racial Minority Clients scale

The purpose of this study was to develop and validate the Concerns about Counseling Racial Minority Clients (CCRMC) scale among counselor trainees. Sample 1 was used for an exploratory factor analysis and confirmatory factor analysis. Four factors were identified, Managing Cultural Differences (α = .82), Offending or Hurting Clients (α = .87), Biased Thoughts and Behaviors (α = .81), and Client Perceptions (α = .77). The coefficient alpha for the CCRMC was .90. The results support the validity of the scale. The scores on the CCRMC and its subscales have positive associations with fear of negative evaluation from others (r = .19 to .40) and negative associations with general counseling self-efficacy (r = -.30 to -.46) and multicultural intervention self-efficacy (r = -.30 to -.64). The CCRMC significantly predicted fear of negative evaluation, session management self-efficacy, and multicultural intervention self-efficacy over and above multicultural social desirability. The validity evidence was not different between White and minority graduate trainees. In Sample 2, the estimated 1-week test-retest reliabilities ranged from .75 to .96 for the CCRMC and its four subscales.     

Response to an intervening event reverses nonspatial repetition effects in 2AFC tasks: Nonspatial IOR?

The repetition effect in two-alternatiave forced choice (2AFC) tasks is a cornerstone effect in human cognition. Yet the experiments described here show that the customary benefit of repetition reverses to a cost of repetition when participants respond to an irrelevant event between targets. In Experiments 1A-1C, participants made manual 2AFC decisions to both of two consecutive targets on a trial and, on some trials, also made a manual response to an intervening event that appeared between the two targets. A repetition benefit was observed when no intervening event appeared, whereas a repetition cost was observed when a response was required to an intervening event. Experiment 2 ruled out a solely strategic interpretation of the repetition cost effect observed on intervening event trials. In Experiments 3A and 3B, an intervening event that required a simple vocal "go" response also produced a repetition cost. In Experiment 4, a repetition cost was observed when the intervening event was changed to a tone presented aurally. In Experiment 5, the repetition benefit was observed when a response was withheld to an intervening event. A dual-process interpretation of these results is discussed, with one process related to episodic integration, and the other related to processes that produce inhibition of return.
