A model of the go/no-go task

In this article, the first explicit, theory-based comparison of 2-choice and go/no-go variants of 3 experimental tasks is presented. Prior research has questioned whether the underlying core-information processing is different for the 2 variants of a task or whether they differ mostly in response demands. The authors examined 4 different diffusion models for the go/no-go variant of each task along with a standard diffusion model for the 2-choice variant (R. Ratcliff, 1978). The 2-choice and the go/no-go models were fit to data from 4 lexical decision experiments, 1 numerosity discrimination experiment, and 1 recognition memory experiment, each with 2-choice and go/no-go variants. The models that assumed an implicit decision criterion for no-go responses produced better fits than models that did not. The best model was one in which only response criteria and the nondecisional components of processing changed between the 2 variants, supporting the view that the core information on which decisions are based is not different between them.     

The Psychology of Nice People

Popular culture often describes being nice as a social disadvantage. However, research repeatedly finds that being agreeable is associated with a number of advantages. Literature noting the positive benefits of being agreeable is reviewed. The paper also addresses how agreeableness, one of the Big Five personality dimensions, is linked with higher-quality friendships, successful parenting, better academic and career performance, and health. The case is made that being agreeable is not equated to being easily influenced nor is it an artifact because of social desirability. Finally, cultural and gender differences related to agreeableness are addressed. Based on the review of the literature, it is postulated that being agreeable may be the path to enduring interpersonal relationships, happiness, success, and well-being.     

A self‐determination theory approach to health and well‐being in the workplace: Results from the sixth European working conditions survey in Spain

Research to date has underlined the importance of positive organizational psychology to improve health and psychological well‐being (PWB) in the workplace. The purpose of the present research is to test a model linking satisfaction of the basic psychological needs for autonomy, competence, and relatedness, as identified by self‐determination theory (SDT), and various individual work‐related outcomes, such as job satisfaction, PWB, and health problems in Spanish employees. Nationally representative data from the sixth European Survey on Working Conditions is Spain were used. Structural equation modeling was performed to examine the mediational role of job satisfaction in the relationships between psychological need satisfaction in the workplace and its consequences for PWB and health problems in Spanish employees. The results indicated that the fulfillment of basic psychological needs in the workplace is related to higher job satisfaction and that higher job satisfaction is associated with higher PWB and fewer health problems. Higher perceived competence and relatedness in the workplace were also related to greater PWB and fewer health problems. These results suggest that SDT is a valid approach that may guide interventions in the workplace to promote job satisfaction, PWB, and physical health in employees.     

Children’s Evaluation and Categorization of Transgender Children

Despite extant evidence of negative peer treatment of transgender adolescents and adults, little is known about how young children perceive transgender peers, particularly those who have socially transitioned or are living in line with their gender rather than sex at birth. Whereas children have been shown to be averse to gender nonconformity in peers, because many transgender children appear and behave in ways consistent with their expressed gender (but not their sex at birth), it is unclear how children evaluate these identities. In 2 studies, we investigated 5- to 10-year-old children’s (N_total = 113) preferences for transgender versus gender-“typical” peers who either shared their gender identity or did not. We also examined whether children categorized transgender peers by their sex or expressed gender, as it might inform their evaluations. Children preferred cisgender peers over transgender peers; however, they also liked peers of their own gender rather than the other gender (e.g., female participants preferred girls over boys), demonstrating that the oft-documented own-gender bias plays an important role even when children are reasoning about transgender peers. Children did not reliably categorize transgender peers by sex or gender; yet those who categorized transgender peers by their sex showed greater dislike of transgender peers. The current studies are the first to investigate cisgender children’s attitudes toward transgender children and suggest that perceptions of gender categorization and conformity play a role in children’s evaluations of transgender peers.

Prevalence of Attention-Deficit/Hyperactivity Disorder Symptoms in 4- to 17-Year-Old Children in the General Population

The purposes of this study were (a) to estimate the prevalence of Attention-Deficit/Hyperactivity Disorder (AD/HD) symptoms in the general preschool and school population; and (b) to analyze the influence of gender, age, and socioeconomic status (SES) variables on AD/HD symptoms. Out of the 80,000 preschool and schoolchildren living in Manizales, Colombia, a random sample of 540 children was selected. Two gender, three age (4- to 5-year olds, 6- to 11 -year olds, and 12- to 17-year olds), and three SES (low, middle, and high) groups were used. The 18 DSM-IV symptoms corresponding to AD/HD Criterion A were assessed on a scale of 0 (never) to 3 (almost always). All three demographic variables established statistically significant differences: AD/HD symptoms were more frequent in 6-to 11-year-old, low-SES, male participants. DSM-IV Criterion A for AD/HD was fulfilled by 19.8% of the boys and 12.3% of the girls. However, this difference was marginally significant only in the AD/HD Subtype I: Combined. It was concluded that demographic variables are significant correlates of the AD/HD diagnosis. The prevalence found in this study was higher than usually reported, even though only the symptomatic DSM-IV AD/HD criterion was analyzed. We failed to confirm the assumed AD/HD gender ratio.     

Artificial grammar learning by 1-year-olds leads to specific and abstract knowledge.

Four experiments used the head-turn preference procedure to assess whether infants could extract and remember information from auditory strings produced by a miniature artificial grammar. In all four experiments, infants generalized to new structure by discriminating new grammatical strings from ungrammatical ones after less than 2 min exposure to the grammar. Infants acquired specific information about the grammar as demonstrated by the ability to discriminate new grammatical strings from those with illegal endpoints (Experiment 1). Infants also discriminated new grammatical strings from those with string-internal pairwise violations (Experiments 2 and 3). Infants in Experiment 4 abstracted beyond specific word order as demonstrated by the ability to discriminate new strings produced by their training grammar from strings produced by another grammar despite a change in vocabulary between training and test. We discuss the implications of these findings for the study of language acquisition.     

Bias in visual attention behavior in a normal school-aged population

Hemi-field visual-spatial attention was studied on a timed letter cancellation task in proficient readers from 7th to 9th grades. Participants maintained greater accuracy in identifying targets in the left quadrants (top/bottom) when compared with the right quadrants (top/bottom), revealing a leftward bias in their responses. Effects of gender and age were evident on performance; females scored significantly higher than males, and 9th graders scored significantly higher than 7th and 8th graders. Thus, a substantial shift in brain maturation may take place from 8th to 9th grades or from the ages of 13.0 to 14.11. Discriminative characteristics of the task are analyzed by assigning greater value to targets located in the top left quadrant. The 9th graders, as compared to the younger students, and the girls, as compared to the boys, evidenced a reading-direction-related bias toward systematic preference for the upper-left to lower-right quadrants.     

Are go/no-go tasks preferable to two-choice tasks in response time experiments with older adults?

Recent research has shown that, in response time (RT) tasks, the go/no-go response procedure produces faster (and less noisy) RTs and fewer errors than the two-choice response procedure in children, although these differences are substantially smaller in college-aged adults. Here we examined whether the go/no-go procedure can be preferred to the two-choice procedure in RT experiments with older adults (i.e. another population with slower and more error-prone responding than college-aged individuals). To that end, we compared these response procedures in two experiments with older adults (M_age?=?83 years): a visual word recognition task (lexical decision) and a perceptual task (numerosity discrimination). A group of young adults (M_age?=?31 years) served as a control. In the lexical decision experiment, results showed a go/no-go advantage in the mean RTs and in the error rates for words; however, this was not accompanied by less noisy RT data. The magnitude of the word-frequency effect was similar in the two response procedures. The numerosity discrimination experiment did not reveal any clear differences across response procedures, except that the RTs were noisier in the go/no-go procedure. Therefore, we found no compelling reasons why the go/no-go procedure should be preferred over the two-choice procedure in RT experiments with older adults.
