Acculturation and mental health: Current findings and recommendations for future research

Results of existing literature suggest that the relationship between acculturation and mental health is complex. Some studies have found a beneficial association between increased acculturation and mental health, whereas others have found a detrimental association or no relationship at all. We reviewed literature on acculturation and mental health in Hispanics/Latino Americans, Asians/Asian Americans, and other ethnic groups. Results indicate that greater acculturation is associated with increased substance use and abuse. Findings for other disorders and symptoms demonstrate considerable heterogeneity and potential reasons for this variation are provided. Acculturation involves a complex set of processes that appear to have differential impact on mental health outcomes. Critical issues in the measurement of acculturation are discussed, and recommendations for future research are offered.     

Interoceptive and exteroceptive cues in the tolerance of the ethanol ataxic effect in rats

In the current analysis of classic conditioning with regard to the phenomenon of drug tolerance, there is empirical evidence of interoceptive pharmacologic cues and of exteroceptive cues, which are associated with the effect of the drug. The former could overshadow the latter. The aim of the present investigation was to contribute experimental data about the interaction that occurs between these two kinds of cues. For this purpose, a set of interoceptive and exteroceptive cues was presented as conditioned stimulus, together with an unconditioned stimulus that corresponded to the ataxic effects of ethanol. The results showed that the interoceptive cues were associated with the ataxic effect of ethanol, and they produced a tolerance response of the same intensity as the exteroceptive cues.     

Selective attention versus selection for action: negative priming is not the result of distractors being unattended

Using a novel referent size-selection task, MacDonald, Joordens, and Seergobin (1999; MacDonald & Joordens, 2000) found that negative priming persisted even when participants were encouraged to attend to distractors before selectively responding to targets. This finding suggested that negative priming is not caused by processes that operate on stimuli that are to be ignored in the traditional selective attention sense. Mackintosh, Mathews, and Holden's (2002) attempt to replicate the MacDonald et al. study resulted in the discovery of possible artifacts in the referent size-selection task, thereby making the implications with respect to the role of attention less clear. In the present study, we describe a different method for directing attention to distractors in a negative priming context, one that does not suffer from the same potential artifacts as the referent size-selection task. Our results are consistent with those found by MacDonald et al., in that negative priming persisted even when participants were explicitly encouraged to attend to distractors. Implications are discussed in the context of the related concepts of selective attention (e.g., Broadbent, 1965) versus selection for action (e.g., Allport, 1987).

Early adolescent sexual debut: The mediating role of working memory ability, sensation seeking, and impulsivity

Although deficits in working memory ability have been implicated in suboptimal decision making and risk taking among adolescents, its influence on early sexual initiation has so far not been examined. Analyzing 2 waves of panel data from a community sample of adolescents (N = 347; Mean age[baseline] = 13.4 years), assessed 1 year apart, the present study tested the hypothesis that weak working memory ability predicts early sexual initiation and explored whether this relationship is mediated by sensation seeking and 2 forms of impulsivity, namely acting-without-thinking and temporal discounting. The 2 forms of impulsivity were expected to be positively associated with early sexual initiation, whereas sensation seeking was hypothesized to be unrelated or to have a protective influence, due to its positive association with working memory. Results obtained from structural equation modeling procedures supported these predictions and in addition showed that the effects of 3 prominent risk factors (Black racial identity, low socioeconomic background, and early pubertal maturation) on early sexual initiation were entirely mediated by working memory and impulsivity. The findings are discussed in regard to their implications for preventing early sexual onset among adolescents. (PsycINFO Database Record (c) 2012 APA, all rights reserved).
