Educational–Occupational Mismatch,Race/Ethnicity,and Immigrant Wealth Attainment

This paper uses wealth attainment as an indicator of economic integration and assesses how educational–occupational mismatch (i.e., over/underqualification) and race/ethnicity affect the wealth attainment of a sample of legal permanent residents in the USA. Using data from the New Immigrant Survey, this paper finds that overqualification is positively associated with wealth attainment, but below the rate for adequately qualified workers in the same occupation. Underqualified immigrants are associated with a pattern of wealth attainment that is equivalent to the adequately qualified. Racial/ethnic wealth inequality among legal permanent residents generally reflects the well-documented pattern among the U.S. native-born. This paper concludes with a discussion that places these results alongside previous research that examines the relationship between educational–occupational mismatch and income among immigrants.     

Poorer aerobic fitness relates to reduced integrity of multiple memory systems

Epidemiological investigations have revealed increases in the prevalence of sedentary behaviors in industrialized societies. However, the implications of those lifestyle choices and related cardiorespiratory fitness levels for memory function are not well-understood. To determine the extent to which cardiorespiratory fitness relates to the integrity of multiple memory systems, a cross-sectional sample of young adults were tested over the course of 3 days in areas related to implicit memory, working memory, long-term memory, and aerobic fitness. Findings revealed an association between aerobic fitness and memory function such that individuals with lower cardiorespiratory fitness exhibited poorer implicit memory performance and poorer long-term memory retention. These data indicate that cardiorespiratory fitness may be important for the optimal function of neural networks underlying these memory systems.     

Subjective frequency ratings for 432 ASL signs

Given the importance of lexical frequency for psycholinguistic research and the lack of comprehensive frequency data for sign languages, we collected subjective estimates of lexical frequency for 432 signs in American Sign Language (ASL). Our participants were 59 deaf signers who first began to acquire ASL at ages ranging from birth to 14 years old and who had a minimum of 10 years of experience. Subjective frequency estimates were made on a scale ranging from 1 = rarely see the sign to 7 = always see the sign. The mean subjective frequency ratings for individual signs did not vary in relation to age of sign language exposure (AoLE), chronological age, or length of ASL experience. Nor did AoLE show significant effects on the response times (RTs) for making the ratings. However, RTs were highly correlated with mean frequency ratings. These results suggest that the distributions of subjective lexical frequencies are consistent across signers with varying AoLEs. The implications for research practice are that subjective frequency ratings from random samples of highly experienced deaf signers can provide a reasonable measure of lexical control in sign language experiments. The Appendix gives the mean and median subjective frequency ratings and the mean and median log(RT) of the ASL signs for the entire sample; the supplemental material gives these measures for the three AoLE groups: native, early, and late.     

Current misuses of multiple regression for investigating bivariate hypotheses: an example from the organizational domain

By definition, multiple regression (MR) considers more than one predictor variable, and each variable’s beta will depend on both its correlation with the criterion and its correlation with the other predictor(s). Despite ad nauseam coverage of this characteristic in organizational psychology and statistical texts, researchers’ applications of MR in bivariate hypothesis testing has been the subject of recent and renewed interest. Accordingly, we conducted a targeted survey of the literature by coding articles, covering a five-year span from two top-tier organizational journals, that employed MR for testing bivariate relations. The results suggest that MR coefficients, rather than correlation coefficients, were most common for testing hypotheses of bivariate relations, yet supporting theoretical rationales were rarely offered. Regarding the potential impact on scientific advancement, in almost half of the articles reviewed (44 %), at least one conclusion of each study (i.e., that the hypothesis was or was not supported) would have been different, depending on the author’s use of correlation or beta to test the bivariate hypothesis. It follows that inappropriate decisions to interpret the correlation versus the beta will affect the accumulation of consistent and replicable scientific evidence. We conclude with recommendations for improving bivariate hypothesis testing.     

Academic Plagiarism at the Faculty Level: Legal Versus Ethical Issues and a Case Study

Plagiarism by college and university faculty members has become a growing issue and concern in academia. This paper presents a case study of an extreme and clear case of such plagiarism. Yet an analysis of the legal and ethical contexts of such plagiarism, and the specific chronicle of this case, illustrate the complexities and difficulties in dealing with such situations. Implications for researchers, for colleges and universities, and for academic publishers and journals are offered.     

Alternatives to switch-cost scoring in the task-switching paradigm: Their reliability and increased validity

In the task-switching paradigm, the latency switch-cost score—the difference in mean reaction time between switch and nonswitch trials—is the traditional measure of task-switching ability. However, this score does not reflect accuracy, where switch costs may also emerge. In two experiments that varied in response deadlines (unlimited vs. limited time), we evaluated the measurement properties of two traditional switch-cost scoring methods (the latency switch-cost score and the accuracy switch-cost score) and three alternatives (a rate residual score, a bin score, and an inverse efficiency score). Scores from the rate residual, bin score, and inverse efficiency methods had comparable reliability for latency switch-cost scores without response deadlines but were more reliable than latency switch-cost scores when higher error rates were induced with a response deadline. All three alternative scoring methods appropriately accounted for differences in accuracy switch costs when higher error rates were induced, whereas pure latency switch-cost scores did not. Critically, only the rate residual and bin score methods were more valid indicators of task-switching ability; they demonstrated stronger relationships with performance on an independent measure of executive functioning (the antisaccade analogue task), and they allowed the detection of larger effect sizes when examining within-task congruency effects. All of the three alternative scoring methods provide researchers with a better measure of task-switching ability than do traditional scoring methods, because they each simultaneously account for latency and accuracy costs. Overall, the three alternative scoring methods were all superior to the traditional latency switch-cost scoring method, but the strongest methods were the rate residual and bin score methods.     

Investigating Several Factors Potentially Related to Endorsing Gambling as an Escape

Previous research has suggested that gambling as an escape is strongly related to disordered gambling. The present study tested whether factors related to disordered gambling were predictive of endorsing gambling as an escape. Three hundred eleven adults from the United States completed several measures of gambling and questionnaires on alcohol expectancies, emotion-regulation strategies, social-adjustment level, and sensation seeking. Consistent with previous research, endorsing gambling as an escape was strongly associated with reporting of gambling problems. Drinking as a coping mechanism and several emotion-regulation strategies were significant predictors of endorsing gambling as an escape. However, levels of social adjustment and sensation seeking were not predictive of gambling as an escape. The present results suggest that escape may be a higher-order factor that links substance abuse and disordered gambling. Likewise, they suggest that endorsing gambling as an escape is rooted in affect. As such, the results are informative to both researchers and practitioners.     

Categorical congruence facilitates multisensory associative learning

Learning about objects often requires making arbitrary associations among multisensory properties, such as the taste and appearance of a food or the face and voice of a person. However, the multisensory properties of individual objects usually are statistically constrained, such that some properties are more likely to co-occur than others, on the basis of their category. For example, male faces are more likely to co-occur with characteristically male voices than with female voices. Here, we report evidence that these natural multisensory statistics play a critical role in the learning of novel, arbitrary associative pairs. In Experiment 1, we found that learning of pairs consisting of human voices and gender-congruent faces was superior to learning of pairs consisting of human voices and gender-incongruent faces or of pairs consisting of human voices and pictures of inanimate objects (plants and rocks). In Experiment 2, we found that this “categorical congruency” advantage extended to nonhuman stimuli, as well—namely, to pairs of class-congruent animal pictures and vocalizations (e.g., dogs and barks) versus class-incongruent pairs (e.g., dogs and bird chirps). These findings suggest that associating multisensory properties that are statistically consistent with the various objects that we encounter in our daily lives is a privileged form of learning.     

Parenting and Prematurity: Understanding Parent Experience and Preferences for Support

Infants born very preterm are at risk of developmental and behavioural problems and their parents are at risk of psychological distress and compromised parenting. This study has two key aims: (1) to identify, from the parents’ own perspective, the unique aspects of parenting an infant born very preterm and (2) to assess parent preferences for support including opinions of a new, tailored parenting intervention, Prem Baby Positive Parenting Program (Triple P). A qualitative approach was taken with focus groups of 18 parents of infants born preterm and a thematic analysis conducted. Parents identified several unique aspects of parenting an infant born preterm including: difficulty coping with the stress of hospitalisation; institutionalisation to the hospital environment; a lack of preparation for the transition to parenthood; grief; isolation; getting into “bad parenting habits” of overnurturance and a lack of certainty about developmental expectations. Parents preferred parenting support that is tailored to parents of infants born preterm, has flexible delivery, enhances coping skills and the spousal relationship and is sensitive to the emotional context of parenting an infant born preterm. Understanding the experiences and the preferences of parents of infants born preterm is an important step in tailoring parenting interventions to fit their needs.
