Racing dragons and remembering aliens: Benefits of playing number and working memory games on kindergartners' numerical knowledge

Sources that contribute to variation in mathematical achievement include both numerical knowledge and general underlying cognitive processing abilities. The current study tested the benefits of tablet‐based training games that targeted each of these areas for improving the mathematical knowledge of kindergarten‐age children. We hypothesized that playing a number‐based game targeting numerical magnitude knowledge would improve children's broader numerical skills. We also hypothesized that the benefits of playing a working memory (WM) game would transfer to children's numerical knowledge given its important underlying role in mathematics achievement. Kindergarteners from diverse backgrounds (n = 148; 52% girls; M_age = 71.87 months) were randomly assigned to either play a number‐based game, a WM game, or a control game on a tablet for 10 sessions. Structural equation modeling was used to model children's learning gains in mathematics and WM across time. Overall, our results suggest that playing the number game improved kindergarten children's numerical knowledge at the latent level, and these improvements remained stable as assessed 1 month later. However, children in the WM group did not improve their numerical knowledge compared to children in the control condition. Playing both the number game and WM game improved children's WM at the latent level. Importantly, the WM group continued to improve their WM for at least a month after playing the games. The results demonstrate that computerized games that target both domain‐specific and domain‐general skills can benefit a broad range of kindergarten‐aged children.

Shopping-Life Balance: Towards a Unifying Framework

Based on a review of the literature we introduce a conceptualization of shopping-life balance, defined as a state of balanced satisfaction between shopping life and other life domains. The new construct involves two dimensions: engagement in shopping life and minimal conflict between social roles in shopping life and roles in other life domains. We argue that engagement in shopping life contributes to satisfaction in shopping life, which in turn contributes to subjective well-being through a bottom-up process. However, engagement in shopping life can lead to role conflict, which causes dissatisfaction in other life domains (e.g., family life, social life, financial life), and in turn detracts from subjective well-being through a bottom-up process. Role conflict may also detract from shopping engagement, thereby reducing satisfaction in shopping life. In the context of this unifying framework we explain much of the research conducted in relation to both shopping engagement and role conflict—predictors or antecedents of shopping engagement and role conflict, namely personal, situational, institutional, and cultural factors involved in shopping-life balance. Research and policy implications are also discussed.

     

Effects of free food deliveries and temporal contiguity on choice under concurrent-chain schedules

Eight pigeons responded in a concurrent chain with variable-interval (VI) 10-sec and VI 20-sec terminal links. Free food deliveries were then added to the initial links according to a variable-time (VT) 20-sec schedule in two conditions that differed in terms of whether a differential reinforcement of other (DRO) contingency was also arranged, which ensured that those deliveries could not occur within 2-sec of a response. Preference for the VI 10-sec terminal link increased when VT food was added, but not when the DRO contingency was operative, showing that free food deliveries affected preference only when those deliveries could be temporally contiguous with choice responding. This finding suggests that Mazur’s (2003) report of increased preference with added VT food, replicated here, was due to adventitious reinforcement. Current models for behavioral choice are limited because they are based entirely on temporal relations between stimuli and reinforcers and fail to take into account response-reinforcer contiguity.     

The modulation of visual orienting reflexes across the lifespan

The development of reflexive and voluntary shifts of visual attention, as well as relations between the two forms of shifting, were examined in three groups of children (5, 7, and 9 years old), one group of young adults (24 years old), and two groups of senior adults (young seniors with an average age of 69 years, and old seniors with an average age of 81 years). The task entailed response to the detection of a target (black dot) in one of four possible locations in the visual field. Relations between reflexive and voluntary shifts of attention were gauged by the degree to which flash and arrow facilitation and inhibition were observed in response to the presentation of both arrow and flash cues together in one trial. All age groups oriented reflexively in response to a flash cue and utilized the arrow cue to orient attention strategically. When flash and arrow cues were presented in quick succession and thereby competed for attention, the youngest children and oldest seniors were least efficient and flexible in their approach to the orienting task as they had difficulty modulating visual reflexes.     

The Psychosocial Construction of Parenting: An Examination of Parenting Goals and Narratives in Relation to Well-Being

In two studies, we examined the implications psychosocial constructions of parenting hold for an understanding of well-being. In studies 1 (N = 504) and 2 (N = 98) participants provided a list of personal goals and narratives about the experience of becoming parents, respectively. In both studies, measures of well-being were also completed. Goals were categorized on the basis of whether they contained reference to parenting as well as agentic and communal motivation, whereas stories were coded for themes of exploration and resolution. In Study 1, the proportion of parenting goals related positively with well-being, although this effect was rendered non-significant after accounting for the communal motivation of parenting goals. In Study 2, themes of exploration and resolution in parents’ narratives positively predicted well-being. Collectively, these results provide intimation of parenting’s “meaningfulness” within the current socio-cultural context.     

The latent structure of social anxiety disorder and the performance only specifier: a taxometric analysis

Social anxiety disorder (SAD) is often treated as a discrete diagnostic entity that represents a naturally occurring class, though empirical evidence largely supports a dimensional conceptualization of social fears. Further, the inclusion of a “performance only” specifier in the DSM-5 implies that individuals who experience intense social anxiety exclusively in performance situations are distinct from those with broader social fears. The purpose of the present research was to examine the latent structure of SAD and the DSM-5 “performance only” specifier in a large nonclinical sample (n = 2019). Three taxometric procedures (MAXCOV, MAMBAC, and L-Mode) were applied to indicators derived from two commonly used measures of social anxiety. Results yielded convergent evidence indicating that social anxiety exhibits a dimensional latent structure. Further, social performance anxiety demonstrates continuous relationships with milder social fears, suggesting that the “performance only” specifier may not represent a discrete entity. The implications of these findings for the assessment, diagnosis, classification, and treatment of social anxiety are discussed.     

Folkbiology meets microbiology: a study of conceptual and behavioral change

Health education can offer a valuable window onto conceptual and behavioral change. In Study 1, we mapped out 3rd-grade Chinese children’s beliefs about causes of colds and flu and ways they can be prevented. We also explored older adults’ beliefs as a possible source of the children’s ideas. In Study 2, we gave 3rd- and 4th-grade Chinese children either a conventional cold/flu education program or an experimental “Think Biology” program that focused on a biological causal mechanism for cold/flu transmission. The “Think Biology” program led children to reason about cold/flu causation and prevention more scientifically than the conventional program, and their reasoning abilities dovetailed with their mastery of the causal mechanism. Study 3, a modified replication of Study 2, found useful behavioral change as well as conceptual change among children who received the “Think Biology” program and documented coherence among knowledge enrichment, conceptual change, and behavioral change.
