Repetitive negative thinking and depressive symptoms are differentially related to response inhibition: The influence of non-emotional, socio-emotional, and self-referential stimuli.

Identifying transdiagnostic correlates of response inhibition deficits is important for understanding risk for internalizing disorders. Little work has compared the relationships between internalizing symptoms and repetitive negative thinking (RNT) with response inhibition across non-emotional and emotional domains, and no work has compared these relationships for inhibition of socio-emotional relative to self-referential stimuli. Undergraduate students (N = 71, 18.44 ± 0.71 years) selected on extremes of internalizing symptoms completed the Perseverative Thinking Questionnaire (PTQ) and a Go/No-Go paradigm using non-emotional stimuli, other individuals' sad facial expressions, and participants' own sad facial expressions. Participants exhibited more commission errors for sad facial expressions than non-emotional trials, though commission errors for others' and participants' own sad facial expressions did not differ. Depressive symptoms were associated with poorer inhibition of non-emotional stimuli; however, PTQ scores were associated with more successful inhibition of non-emotional stimuli. Our results provide evidence that transdiagnostic RNT as assessed by the PTQ may be related to better inhibition in non-emotional domains, but negative emotional stimuli may interfere with successful inhibition for those with high RNT, while depressive symptoms were linked to poorer inhibition of non-emotional stimuli. These findings have implications for internalizing disorders, which often are accompanied by RNT.

Selection and Characterization of Cultural Priming Stimuli for the Activation of Spanish and English Cultural Mindsets among Hispanic/Latino Bilinguals in the United States.

Cultural priming studies frequently employ non-validated, stereotypical images. Here, we select images to separately evoke two cultural mindsets: Hispanic and US-American. Spanish-English bilinguals identifying as Hispanic/Latino (N=149) rated 50 images online for their cultural and emotional evocation. Based on relative cultural identification, cultural "delegate" (strongly US-American, strongly Hispanic, balanced bicultural) subsamples' ratings were averaged to isolate particularly salient images. Image ratings were compared across respondents' national origins. Ratings of seven selected pairs of content-matched Hispanic and US-American primes were compared across the full sample. High discrimination across cultural mindsets and positive emotion ratings were maintained regardless of various demographic factors. Thus, we provide empirical justification for incorporating these stimuli, individually or as sets, within cultural priming studies among Hispanic/Latino samples.
