Knowing what a novel word is not: Two-year-olds 'listen through' ambiguous adjectives in fluent speech

Three studies investigated how 24-month-olds and adults resolve temporary ambiguity in fluent speech when encountering prenominal adjectives potentially interpretable as nouns. Children were tested in a looking-while-listening procedure to monitor the time course of speech processing. In Experiment 1, the familiar and unfamiliar adjectives preceding familiar target nouns were accented or deaccented. Target word recognition was disrupted only when lexically ambiguous adjectives were accented like nouns. Experiment 2 measured the extent of interference experienced by children when interpreting prenominal words as nouns. In Experiment 3, adults used prosodic cues to identify the form class of adjective/noun homophones in string-identical sentences before the ambiguous words were fully spoken. Results show that children and adults use prosody in conjunction with lexical and distributional cues to ‘listen through’ prenominal adjectives, avoiding costly misinterpretation.     

Prediction of psychological reactions to bone density screening for osteoporosis using a cognitive-behavioral model of health anxiety

Pre-screening measures derived from a cognitive-behavioral theory of health anxiety were significant predictors of individual differences in post-screening reactions to a health screening procedure, bone densitometry. Predictors included specific illness beliefs (vulnerability, severity/consequences, coping and treatment) and general health anxiety measures. Three months after a low bone mineral density (BMD) result, women with high levels of pre-existing general health anxiety gave higher ratings of anxiety about osteoporosis and perceived likelihood of developing osteoporosis than women with low levels of preexisting health anxiety, even though the two groups' initial ratings had not differed significantly. Women with a low BMD result generally showed "minimization" of the seriousness of low BMD but women with very high levels of pre-existing health anxiety did not. After a high BMD result, highly health anxious women were only temporarily reassured. The results were consistent with the cognitive-behavioral analysis of health anxiety.     

Independence and dependence in human causal reasoning

Causal graphical models (CGMs) are a popular formalism used to model human causal reasoning and learning. The key property of CGMs is the causal Markov condition, which stipulates patterns of independence and dependence among causally related variables. Five experiments found that while adult’s causal inferences exhibited aspects of veridical causal reasoning, they also exhibited a small but tenacious tendency to violate the Markov condition. They also failed to exhibit robust discounting in which the presence of one cause as an explanation of an effect makes the presence of another less likely. Instead, subjects often reasoned “associatively,” that is, assumed that the presence of one variable implied the presence of other, causally related variables, even those that were (according to the Markov condition) conditionally independent. This tendency was unaffected by manipulations (e.g., response deadlines) known to influence fast and intuitive reasoning processes, suggesting that an associative response to a causal reasoning question is sometimes the product of careful and deliberate thinking. That about 60% of the erroneous associative inferences were made by about a quarter of the subjects suggests the presence of substantial individual differences in this tendency. There was also evidence that inferences were influenced by subjects’ assumptions about factors that disable causal relations and their use of a conjunctive reasoning strategy. Theories that strive to provide high fidelity accounts of human causal reasoning will need to relax the independence constraints imposed by CGMs.     

Postural control in children with and without neurofibromatosis type 1

Previous research has evaluated the motor proficiency of children with neurofibromatosis type 1 (NF1) and found delays on the balance subtest. However the balance subtest was found to have low sensitivity for identifying balance impairments. This study examines the differences in postural control between children with NF1 and peers with typical development using a force plate. A single limb stance test on a force plate was completed for all participants. The force plate variables, center of pressure maximum distance in the anterior/posterior direction (COPmax A/P) and center of pressure velocity (COPvel A/P) were compared between groups. The NF1 group’s performance was significantly poorer than the control group in both COPmax A/P (p = .01) and COPvel A/P (p = .01). When separated into specific age ranges, only the children in the NF1 group between 5 and 12 years of age demonstrated statistically significant differences in the COP variables. The COP variables for the 13- to 18-year-old group were not significantly different. These results indicate that young children with NF1 have poor postural control. However, postural control appears to improve with maturation.     

The Questionnaire Big Six in 26 Nations: Developing Cross‐Culturally Applicable Big Six,Big Five and Big Two Inventories

The Big Five is a useful model of attributes now commonly used in cross‐cultural research, but without the support of strong measurement invariance (MI) evidence. The Big Six has been proposed as a cross‐culturally informed update, and the broader Big Two (Social Self‐Regulation and Dynamism) draws on even more cross‐cultural evidence. However, neither has been rigorously tested for cross‐cultural MI. Here a Big Six inventory (36QB6) and measures of the Big Five and Big Two derived from it were tested and refined for cross‐cultural usability in samples from 26 nations, divided into three subsets. Confirmatory factor analysis of the models in the first subset of nations demonstrated fit as strong in translation as typical personality measures achieve in their nation of origin (although poor per standard benchmarks). Items that performed inconsistently across cultures were removed, and alternates considered in a second subset of nations. Fit and invariance were improved for refined 30‐item QB6, 25‐item Big Five and 14‐item Big Two measures in the third subset of nations. For all models, decrease in comparative fit index between MI levels was larger than .01, indicating lack of support for higher levels. Configural and factorial invariance were relatively stronger, compared to scalar and full. Copyright © 2014 European Association of Personality Psychology     

When saying no leads to compliance: The door-in-the-face technique for changing attitudes and behaviors towards smoking at work

IntroductionThe aim of this action research was to encourage workers to comply with an anti-smoking charter and get them to effectively reduce their tobacco use. Two change procedures were compared: a classic one based on an information campaign and an original one based on the door-in-the-face technique.MethodForty-three smoking workers participated in this study. They were assigned to one of the two groups: information campaign group or door-in-the-face group. Two types of measures were administered. The first assessed self-reported attitudes towards smoking, such as perceived dependence (Fagerström Test); the second assessed effective behavior, such as number of cigarettes smoked and physiological nicotine addiction.ConclusionTaken together, the results show that the door-in-the-face technique was more effective than the information campaign. These results are discussed in light of the social acceptability of the initial refusal.     

Screening Solid Foods Infants 1 (SSFI-1) development of a screening tool to detect problems in the transition from milk to solid food in infants from six to nine months of age

AimTo establish the psychometric properties of a newly developed screening tool Screening Solid Foods Infants 1 (SSFI-1) used by early childhood professionals, to detect problems in the transition from milk to solid food of smooth consistency in infants 6–9 months of age.MethodsThe SSFI-1 score was filled out by the parents of a subgroup with term infants (n = 35); healthy preterm infants (n = 26); infants with comorbidity (n = 17); infants with feeding problems (n = 13). Internal consistency, reproducibility, construct, criterion and related validity was evaluated.ResultsThe preterm subgroup differed significantly in age when starting with fruits/vegetables and period of experience (p < 0.01). The SSFI-1 was sufficiently reliable for the total group and term subgroup (α = 0.78 and 0.76), but not for the preterm and comorbidity/feeding problem subgroup (α = 0.51 and 0.69). Inter-rater reliability was high for the total score (n = 25, ICC r = 0.93), and moderate to good for individual items (weighted kappa range 0.55–0.95). Validity was confirmed by significantly higher scores for the comorbidity/feeding problem subgroups and clinically distinguishable subgroups (p < 0.05) and area under the curve values > 0.78. The initial 10-item screening tool was modified to a seven item screening tool. A SSFI-1 score of 4, +2 SD of the term subgroup, had 76.9% sensitivity and 82.1% specificity, for detecting the presence of a feeding problem.ConclusionThe seven-item screening tool Screening Solid Foods 1 may be used as a screening tool for term infants. Further testing of the SSFI-1 in new infants is needed, to confirm reliability and validity both for term, preterm and (risk for) feeding problem infants.     

Relationships of career adaptabilities with explicit and implicit self-concepts

Career adaptability is a psychosocial construct that incorporates a set of essential resources to one's career development. The adaptability resources' relevance is even higher when it comes to former communist countries, such as Romania, where job security and stability were seen as central benefits for workers. The aim of this study was to provide a more comprehensive understanding of the stable underpinnings of career adaptabilities by exploring their relationships with aspects of the self that are driven by automatic processes and that are less affected by self-presentation biases. A sample of 359 participants completed the Career Adapt Abilities Scale (CAAS)-Romanian form, out of which a subsample of 212 participants also completed a set of scales comprising explicit and implicit measures of conscientiousness, extraversion, neuroticism, and self-esteem. Results revealed nonsignificant additive contributions of the implicit self-concept measures over what was already explained by the explicit self-concepts. The most noticeable effect resides in the significant interaction between explicit and implicit self-esteem in relation to control, confidence, and overall adaptability. These results reveal that individuals with high explicit and low implicit self-esteem perceive themselves as being the most adaptable. Notably, these results were obtained using a Romanian version of CAAS that possesses very good psychometric properties (i.e., excellent internal consistencies, the same four-factor multidimensional solution, replicated patterns of associations between CAAS and explicit self-concepts of personality).
