Effects of Interspersing Briefer Mathematics Problems on Assignment Choice in Students with Learning Disabilities

Within- and between-series designs were combined and used to evaluate the effects of interspersing briefer math problems (i.e., one-digit by one-digit multiplication, 1 × 1) with more time-consuming problems (i.e., two-digit by one-digit multiplication, 2 × 1) on time allocation to one of two concurrent computer-delivered mathematics computation assignments in four high school students with specific learning disabilities in mathematics. The computer presented students with a choice of 2 × 1 problems with 1 × 1 problems interspersed every third problem (i.e., experimental assignment) or 2 × 1 problems without interspersal (i.e., control assignment). Visual and statistical analysis showed that students allocated a greater percentage of their time to the interspersal assignments. These results support previous research on the matching law and problem completion rates and suggest that students' preference for assignments can be improved through the interspersal technique. Discussion focuses on future research and applied educational implications for curricula construction and task sequencing.     

Motivational systems of social behavior in male rats and monkeys: Are they homologous?

A comparison is presented between the behaviors of male rats and male stumptail macaques that occur when two unfamiliar males are paired for 10 min. Results which have been presented in detail in separate papers elsewhere are compared and discussed here in terms of the hypothetical organization of motivational systems. The following motivational mechanisms appear to be homologous in the rat and monkey: offense, defense, submission, male sex, self grooming, and allogrooming. Two motivational mechanisms are analogous but not homologous: patrol/marking in the rat and display in the monkey. There is a shift in sensory modality of motivating stimuli from olfaction in the rat to complex visual and auditory stimuli in the monkey. There is also a shift in the modalities of motor patterns from predominant use of the mouth by the rat to use of the hands by the monkey. Both shifts affect most or all motivational systems of social behavior. It is hypothesized that the outer parts of motivational systems, their sensory and motor interfaces with the environment, change more rapidly and incrementally during the course of mammalian evolution than does the inner part, the integrational portion that consists of the motivational mechanisms.     

Face averages and multiple images in a live matching task

We know from previous research that unfamiliar face matching (determining whether two simultaneously presented images show the same person or not) is very error-prone. A small number of studies in laboratory settings have shown that the use of multiple images or a face average, rather than a single image, can improve face matching performance. Here, we tested 1,999 participants using four-image arrays and face averages in two separate live matching tasks. Matching a single image to a live person resulted in numerous errors (79.9% accuracy across both experiments), and neither multiple images (82.4% accuracy) nor face averages (76.9% accuracy) improved performance. These results are important when considering possible alterations which could be made to photo-ID. Although multiple images and face averages have produced measurable improvements in performance in recent laboratory studies, they do not produce benefits in a real-world live face matching context.     

Driver behaviour and traffic accident involvement among professional urban bus drivers in China

The present research aimed to investigate specific behaviors of professional urban bus drivers in China with the revised Driver Behavior Questionnaire (DBQ), and to define the relationships among various driving behaviors (errors, positives, inattention errors, violations), background information (age, years of driving experience, mobility, etc.), self-assessment, and traffic accident. To achieve such goals, the present research designed a four-dimensional DBQ with 20 items for professional urban bus drivers in China. The KMO coefficient of the whole scale was 0.835, and Bartlett’s test was statistically significant (p < 0.000), which demonstrated strong validity of the scale and should be suitable for factor analysis. The four loading factors accounted for 58.991%. In addition, the reliability and effectiveness of the present 20-item scales were measured. The coefficient of internal consistency-Cronbach’s alpha coefficient was 0.881 and the Cronbach’s Alpha Based on Standardized Items was 0.911. This showed that driving behavior scale of professional bus drivers in China was of high reliability and validity. The analysis showed that among the four factors, positive driving behaviors were significantly associated with errors, inattention errors and violations, respectively. Errors, inattention errors and violations correlated positively with each other. This verified that the correlation coefficient of each factor was medium and high, which indicated that the scale had good difference validity. The test content of the total scale was also highly consistent with the test content of each factor, which indicated that the revised scale had good standard related validity. According to the accident prediction model, the variables that significantly affected the occurrence of traffic accidents were daily driving time, positive driving behavior, SE2 (Driving safety), SE3 (Aberrant driver behaviors). The results showed that professional bus drivers often working overtime were most likely to have accidents. The probability of traffic accidents decreased by 53% for every unit of positive driving behavior frequency of professional bus drivers. The more they felt that they had the tendency of aberrant driving behavior, the more likely they were to have traffic accidents. To summary, the present research contributed to validating and improving the DBQ for professional urban drivers in China.     

Integrating meaning in life and self-determination theory to predict physical activity adoption in previously inactive exercise initiates enrolled in a randomized trial

Self-Determination Theory (SDT) suggests that individuals with greater basic psychological needs satisfaction and autonomous motivation are more likely to adopt physical activity (PA). However, few longitudinal studies have examined these processes in exercise initiates outside the context of a formalized intervention. Further, an implicit yet relatively unexplored tenet of SDT is that when behaviors are closely connected to what is meaningful to individuals, those behaviors are more likely to be maintained. This study had two aims: (a) to examine SDT and a sense of meaning in life (MIL) in relation to PA in previously inactive exercise initiates, and (b) to determine whether daily measurement of MIL, mood, and PA impacts PA engagement. Upon joining a fitness center, participants (N = 160; M age = 43.3 years; 77% female) were recruited for a longitudinal study of PA adoption. Participants were randomized to a daily measurement condition (self-monitoring) where they reported daily MIL, mood, and PA or to an attention control condition. All participants self-reported their PA, basic psychological needs satisfaction, behavioral exercise regulation, and MIL at baseline, 4-weeks, and 12-weeks after starting an exercise program. Longitudinal path models were used to examine the relationships among study variables. Cross-sectionally, SDT constructs were largely related to PA in the expected directions. After accounting for SDT processes, baseline MIL was associated with greater PA at 4-weeks (p = .028). There were no differences in PA, SDT constructs, or MIL between the measurement self-monitoring and control groups. MIL predicted PA adoption above and beyond SDT predictors in previously inactive adults. Combined SDT and MIL intervention approaches may enhance PA adoption, and further research should explore their roles in PA adoption and maintenance.     

Modeling self on others: An import theory of subjectivity and selfhood

This paper outlines an Import Theory of subjectivity and selfhood. Import theory claims that subjectivity is initially perceived as a key feature of other minds before it then becomes imported from other minds to own minds whereby it lays the ground for mental selfhood. Import theory builds on perception-production matching, which in turn draws on both representational mechanisms and social practices. Representational mechanisms rely on common coding of perception and production. Social practices rely on action mirroring in dyadic interactions. The interplay between mechanisms and practices gives rise to model self on others. Individuals become intentional agents in virtue of perceiving others mirroring themselves. The outline of the theory is preceded by an introductory section that locates import theory in the broader context of competing approaches, and it is followed by a concluding section that assesses import theory in terms of empirical evidence and explanatory power.     

Bidirectional Spillover in the Family across the Transition to Parenthood

Although family systems theory posits reciprocal causality between subsystems of the family, such as intimate partner violence exacerbating harsh parenting and vice versa, longitudinal studies with cross‐lagged models have been used infrequently to test these principles. As guided by the spillover model, this study examined bidirectional associations between couple dysfunction, parent–child aggression risk, and child functioning across the transition to parenthood to determine whether and how disruptions in one subsystem relate to problems in other family subsystems. Participants were 201 first‐time mothers and 151 fathers from a diverse community sample, evaluated during pregnancy, and reassessed two more times through their child's first 18 months of life. Individual and dyadic path model results indicate bidirectional spillover effects between parent–child aggression risk and child functioning for both mothers and fathers, and spillover from parent–child aggression risk to couple dysfunction for mothers but not fathers. However, limited spillover effects were identified between couple functioning and child adjustment, in contrast to previous work. Findings suggest that spillover can happen reciprocally and early in the family, supporting transactional models of behavior and highlighting the need for early family level intervention.

亲组织不道德行为(Unethical Pro-organizational Behavior, UPB)界定的是组织员工出于维护组织的利益而做出的不道德行为。UPB在组织中难以被识别, 却可能给组织带来严重的负面影响。因兼具亲组织性和不道德性, UPB的研究引起了各界的广泛关注。因此, 有必要明确UPB的来源与界定; 亦有必要借鉴“不道德行为”的解释路径, 从理性决策和直觉判断两个解释机制对UPB前因研究取得的进展进行理论归纳梳理, 形成理论模型。在此基础上提出未来的研究方向:亲领导不道德行为和亲团队不道德行为的细分研究, 中国本土背景下企业所有制形式对UPB理论模型可能产生的调节作用, 以及角色压力对UPB的影响。     

Continuous measurement of attachment behavior: A multimodal view of the strange situation procedure

Infant attachment is a critical indicator of healthy infant social-emotional functioning, which is typically measured using the gold-standard Strange Situation Procedure (SSP). However, expert-based attachment classifications from the SSP are time-intensive (with respect both to expert training and rating), and do not provide an objective, continuous record of infant behavior. To continuously quantify predictors of key attachment behaviors and dimensions, multimodal movement and audio data were collected during the SSP. Forty-nine 1-year-olds and their mothers participated in the SSP and were tracked in three-dimensional space using five synchronized Kinect sensors; LENA recordings were used to quantify crying duration. Theoretically-informed multimodal measures of attachment-related behavior (e.g., dyadic contact duration, infant velocity of approach toward the mother, and infant crying) were used to predict expert rating scales and dimensional summaries of attachment outcomes. Stepwise regressions identified sets of multimodal objective measures that were significant predictors of eight of nine of the expert ratings of infant attachment behaviors in the SSP’s two reunions. These multimodal measures predicted approximately half of the variance in the summary approach/avoidance and resistance/disorganization attachment dimensions. Incorporating all objective measures as predictors regardless of significance levels, predicted individual ratings within an average of one point on the original Likert scales. The results indicate that relatively inexpensive Kinect and LENA sensors can be harnessed to quantify attachment behavior in a key assessment protocol, suggesting the promise of objective measurement to understanding infant-parent interaction.     

儿童期遭受心理虐待个体的自我加工特点

儿童期心理虐待会导致个体形成消极自我,这种消极自我还会影响个体行为。与以往研究采用自我报告方法不同,本研究采用知觉匹配范式,用客观量化方法,以自我加工优势（自我关联会自动增强刺激的加工,表现为人们总是对自己相关信息加工又快又好）来评估儿童期遭受心理虐待个体的自我加工能力。结果发现,儿童期遭受心理虐待个体依然存在自我加工优势,且朋友加工优势得到增强;在消极情绪条件下遭受心理虐待个体自我优势稳定存在,在积极情绪条件其自我优势消失。结论：儿童期遭受心理虐待个体自我整合功能并不稳定,消极情绪维持其自我加工能力,积极情绪则降低其自我加工能力。
