Cross-linguistic phonotactic competition and cognitive control in bilinguals

The current study examines the relation between cognitive control and linguistic competition resolution at the sublexical level in bilinguals. Twenty-one Spanish–English bilinguals and 23 English monolinguals completed a non-linguistic Stroop task (indexing inhibitory control) and a linguistic priming/lexical decision task (indexing Spanish phonotactic-constraint competition during English comprehension). More efficient Stroop performance (i.e. a smaller Stroop effect) in bilinguals was associated with decreased competition from Spanish phonotactic constraints during English comprehension. This relation was observed when nonword targets overlapped in phonotactic constraints and phonological form with preceding cognate primes (e.g. prime: stable (Spanish: estable)/target: esteriors). Findings suggest a link between non-linguistic cognitive control and co-activation of linguistic structures at the sublexical level in bilinguals.     

A comparison of Chinese and American memories for public events

Memory for public events was compared across Chinese and U.S. participants to explore competing explanations for cultural differences in flashbulb memories. Participant recall of the canonical features of events was more detailed and more likely to include a specific time in the United States than in the Chinese reports. Vividness was positively correlated with the flashbulb memory scores only in the U.S. sample. In both cultures, emotion, national importance, and thinking about the event predicted vividness and recall of memory details. Chinese participants reported primarily disasters and social events, and their memories were more likely to include international events than U.S. participants. The U.S. participants recalled primarily political events and terrorism. These results suggest that culture has important influences on the quantity, level of detail, completeness, and vividness of autobiographical memories as well as on the types of events triggering flashbulb memories.     

“At least one” problem with “some” formal reasoning paradigms

In formal reasoning, the quantifier "some" means "at least one and possibly all." In contrast, reasoners often pragmatically interpret "some" to mean "some, but not all" on both immediate-inference and Euler circle tasks. It is still unclear whether pragmatic interpretations can explain the high rates of errors normally observed on syllogistic reasoning tasks. To address this issue, we presented participants (reasoners) in the present experiments either standard quantifiers or clarified quantifiers designed to precisely articulate the quantifiers' logical interpretations. In Experiment 1, reasoners made significantly more logical responses and significantly fewer pragmatic responses on an immediate-inference task when presented with logically clarified as opposed to standard quantifiers. In Experiment 2, this finding was extended to a variant of the immediate-inference task in which reasoners were asked to deduce what followed from premises they were to assume to be false. In Experiment 3, we used a syllogistic reasoning task and observed that logically clarified premises reduced pragmatic and increased logical responses relative to standard ones, providing strong evidence that pragmatic responses can explain some aspects of the errors made in the syllogistic reasoning task. These findings suggest that standard quantifiers should be replaced with logically clarified quantifiers in teaching and in future research.     

Refining the relationship between personality and subjective well-being

Understanding subjective well-being (SWB) has historically been a core human endeavor and presently spans fields from management to mental health. Previous meta-analyses have indicated that personality traits are one of the best predictors. Still, these past results indicate only a moderate relationship, weaker than suggested by several lines of reasoning. This may be because of commensurability, where researchers have grouped together substantively disparate measures in their analyses. In this article, the authors review and address this problem directly, focusing on individual measures of personality (e.g., the Neuroticism-Extroversion-Openness Personality Inventory; P. T. Costa & R. R. McCrae, 1992) and categories of SWB (e.g., life satisfaction). In addition, the authors take a multivariate approach, assessing how much variance personality traits account for individually as well as together. Results indicate that different personality and SWB scales can be substantively different and that the relationship between the two is typically much larger (e.g., 4 times) than previous meta-analyses have indicated. Total SWB variance accounted for by personality can reach as high as 39% or 63% disattenuated. These results also speak to meta-analyses in general and the need to account for scale differences once a sufficient research base has been generated.     

Right hemisphere metaphor processing? Characterizing the lateralization of semantic processes

Previous laterality studies have implicated the right hemisphere in the processing of metaphors, however it is not clear if this result is due to metaphoricity per se or another aspect of semantic processing. Three divided visual field experiments varied metaphorical and literal sentence familiarity. We found a right hemisphere advantage for unfamiliar sentences containing distant semantic relationships, and a left hemisphere advantage for familiar sentences containing close semantic relationships, regardless of whether sentences were metaphorical or literal. This pattern of results is consistent with theories postulating predominantly left hemisphere processing of close semantic relationships and predominantly right hemisphere processing of distant semantic relationships.     

Discomfort intolerance: evaluation of a potential risk factor for anxiety psychopathology

Discomfort intolerance, defined as an individual difference in the capacity to tolerate unpleasant bodily sensations, is a construct recently posited as a risk factor for panic and anxiety psychopathology. The present report used a biological challenge procedure to evaluate whether discomfort intolerance predicts fearful responding beyond the effects of trait anxiety and a well-established psychological vulnerability factor (i.e., anxiety sensitivity). Nonclinical community participants (N=44) with no history of panic attacks or any Axis I condition completed a 35% CO(2) challenge. Results are consistent with our hypothesis suggesting that discomfort intolerance incrementally predicts increased subjective reactivity to the challenge. Moreover, there was some suggestion that discomfort intolerance interacted synergistically with anxiety sensitivity to increase anxiety-related symptoms. These findings add to a small but growing literature suggesting that discomfort intolerance may play a role in the development of anxiety problems.     

No retrieval-induced forgetting using item-specific independent cues: evidence against a general inhibitory account

Retrieval practice with particular items from memory can impair the recall of related items on a later memory test. This retrieval-induced forgetting effect has been ascribed to inhibitory processes (M. C. Anderson & B. A. Spellman, 1995). A critical finding that distinguishes inhibitory from interference explanations is that forgetting is found with independent (or extralist) cues. In 4 experiments, the authors tested whether the forgetting effect is cue-independent. Forgetting was investigated for both studied and unstudied semantically related items. Retrieval-induced forgetting was not found using item-specific independent cues for either studied or unstudied items. However, forgetting was found for both item types when studied categories were used as cues. These results are not in line with a general inhibitory account, because this account predicts retrieval-induced forgetting with independent cues. Interference and context-specific inhibition are discussed as possible explanations for the data.     

The relationship between guardian certification requirements and guardian sanctioning: a research issue in elder law and policy

This study investigated the relationship between guardian certification requirements and guardian sanctioning in the state of Washington. A total of 377 files were examined. Findings show that 52.4% of guardians with an undergraduate degree or higher education are likely to be sanctioned compared with 42.2% with an Associate of Arts (AA) or Technical (Tech) degree, and 36.9% with a high school diploma (HS) or equivalency (GED). Guardians with an undergraduate or higher education are 1.88 times more likely to be sanctioned compared with GED or HS graduates (p < 0.05). However, 83.3% of GED or HS graduates are likely to have more severe sanctions compared with 76.4% undergraduate or higher education, and 47.7% with an AA or Tech degree, respectively. Guardians with an AA or Tech degree are 0.28 times less likely to have more severe sanctions than guardians with an undergraduate degree or higher education (p < 0.01). The results are discussed with respect to guardian registration, licensing, certification and quality; licensing and regulation of other professions; the limitations of the study; and the need for further research.     

Specific Aptitude Theory Revisited: Is There Incremental Validity for Training Performance?

There has been controversy over the years about whether specific mental abilities increment validity for predicting performance above and beyond the validity for general mental ability (GMA). Despite its appeal, specific aptitude theory has received only sporadic empirical support. Using more exact statistical and measurement methods and a larger data set than previous studies, this study provides further evidence that specific aptitude theory is not tenable with regard to training performance. Across 10 jobs, differential weighting of specific aptitudes and specific aptitude tests were found not to improve the prediction of training performance over the validity of GMA. Implications of this finding for training research and practice are discussed.
