Effects of a 12-month pedometer walking program on gait, body mass index, and lower extremity function in obese women

This study evaluated the effects of a self-reported pedometer-walking program on gait, lower extremity function, and Body Mass Index for 33 obese women, ages 31-65 years (M = 48.0, SD = 8.0) and whose initial average Body Mass Index was 40.30 +/- 9.60 kg/m2. During the 12-mo. intervention participants wore pedometers and reported the number of daily steps walked. Body Mass Index, three gait parameters, steps/day, and lower extremity function were taken over 3-mo. intervals. All participants increased in gait velocity, % single-leg support, and lower extremity function, and decreased in Body Mass Index over time. Those whose steps/day increased by 2000 over 6 mo. had significantly faster velocities and longer step lengths than those whose steps/day did not increase. The 1-yr. walking program stimulated changes in gait, Body Mass Index, and lower extremity function for these obese women. Ultimately, these changes may reduce the risk of falls for this group of women.     

Short-duration, high-intensity exercise and performance of a sports-specific skill: a preliminary study

The purpose of this study was to examine the effect of one bout and three intermittent bouts of short-duration, high-intensity running on the performance of a sports-specific psychomotor skill. Participants (N=13) were male soccer players (M age 20.5 yr., SD=2.0) who had been playing semi-professionally for M=2.1 years, SD=1.11 and trained twice a week. They undertook a soccer-passing test in three conditions: following rest, following a 100-m sprint and following 3 x 100-m sprints, with 30-sec. rest intervals between sprints. Passing accuracy showed a significant linear deterioration, while number of passes showed a significant quadratic effect. Low to moderate linear regression correlations were found between posttest heart rate and absolute and variable errors on the test. It was concluded that short-duration, high-intensity exercise has a negative effect on accuracy in a sports-specific task that requires both perceptual judgment and motor control.     

Social outcomes in childhood brain disorder: a heuristic integration of social neuroscience and developmental psychology

The authors propose a heuristic model of the social outcomes of childhood brain disorder that draws on models and methods from both the emerging field of social cognitive neuroscience and the study of social competence in developmental psychology/psychopathology. The heuristic model characterizes the relationships between social adjustment, peer interactions and relationships, social problem solving and communication, social-affective and cognitive-executive processes, and their neural substrates. The model is illustrated by research on a specific form of childhood brain disorder, traumatic brain injury. The heuristic model may promote research regarding the neural and cognitive-affective substrates of children's social development. It also may engender more precise methods of measuring impairments and disabilities in children with brain disorder and suggest ways to promote their social adaptation.     

Indirect evidence and the poverty of the stimulus: the case of anaphoric one

It is widely held that children's linguistic input underdetermines the correct grammar, and that language learning must therefore be guided by innate linguistic constraints. Here, we show that a Bayesian model can learn a standard poverty-of-stimulus example, anaphoric one , from realistic input by relying on indirect evidence, without a linguistic constraint assumed to be necessary. Our demonstration does, however, assume other linguistic knowledge; thus, we reduce the problem of learning anaphoric one to that of learning this other knowledge. We discuss whether this other knowledge may itself be acquired without linguistic constraints.     

The effect of consequential thinking on trust game behavior

Contrary to rational Expected Monetary Value (EMV) predictions that no money will be transferred in Trust Games, in experiments players make positive transfers. Theorists have proposed modifying the Sender's utility function while retaining utility‐maximization assumptions to account for this behavior. Such accounts assume that Senders can grasp the possible outcomes of their choices, their probabilities, and utilities. In reality, however, Senders' choices are unexpectedly complex, and the assumption that they approximate expected utility maximization is highly implausible. Instead, we suggest that Senders are guided by general propensities to trust others. Two experiments examine the effect of inducing consequential thought on Sender behavior. One induced consequential thought directly; the other did so indirectly. The amount sent was significantly reduced following either manipulation. This suggests that models of Sender behavior in Complex Trust Games should not assume that participants routinely engage in consequential thinking (CT) of the depth that would be required for utility maximization.

Antecedents for achievement of alignment in organizations

This study investigated potential antecedents of the alignment of organizational subunits' processes and goals with the organization's primary goals and therefore with each other. Alignment data of 329 aggregated subunits (7,359 employees), organization‐wide, of a large US manufacturing company were examined. Managerial effectiveness, communication about goals and objectives, and employee enhancement positively related with alignment at a group or subunit level. Alignment, in‐turn, positively related with company satisfaction at an individual level. Moreover, 95% of the variation in satisfaction across subunits could be explained by alignment and its antecedents.     

Coorientation of body image among older married couples

This study examined how older husbands and wives perceived their bodies and appearance in the framework of coorientation effect. Data were collected via a mail survey of older married couples residing in three metropolitan areas in Florida. A total of 94 married couples who were 60 years older participated in this study. Results indicated that older husbands’ self-assessment of appearance was positively correlated with wives’ self-assessment of appearance. Husbands’ evaluation of their wives’ appearance was positively associated with wives’ self-assessment of their own appearance (self-other agreement), and wives’ evaluation of their husbands’ appearance was also positively correlated with husbands’ self-assessment of their own appearance (self-other agreement). In addition, husbands’ evaluation of their wives’ appearance corresponded to wives’ evaluation of their husbands’ appearance (reciprocity). These results indicated that the agreement in two spouses’ self-assessment of appearance can be explained by the two coorientation effects (self-other agreement and reciprocity) occurred in two partners of married couples.     

The Concept of Situations

The concept of situations has a long past, but the conceptualization of situations only has a short history. This article provides a survey of the concept of situations. Based upon Milgram’s [Human Relations 18 (1965), 57] vision toward ‘a compelling theory of situations,’ the authors examine the concept of situations in three specific literatures: definitions of situations, taxonomies of situations, and interrelationships among persons, situations, and behaviors. To further integrate the literature, the authors propose that the essence of a situation is its affordance of human goals, and that situations are largely characterized by two specific principles of goal processes (what happened, is happening, or might happen to people’s goals) and goal contents (the specific goals afforded in the situation).
