Perceived motivational climate and unit cohesion: The case of French soldiers in training

Using a correlational design, this exploratory research investigates the relationships between soldiers’ perceptions of the motivational climate created by platoon leaders and unit cohesion in a French military sample. Conducted among 257 soldiers, the findings indicate that new recruits perceive motivational climate as significantly more task- than ego-involved. Moreover, multiple regressions show that a task-involving motivational climate predicts higher measures of cohesion than does an ego-involving motivational climate. Implications for the professionalization of military forces and exercising command in training are discussed.     

感知到亲子间面孔相似性对亲子虐待的影响：一个双重调节模型

由于体内受精,父亲面临着父亲身份不确定性的风险,亲子间面孔相似性是辨别父亲身份的一个常用的有效线索,因此,父亲往往依据亲子间面孔相似性程度调整着亲子投资。而中国传统文化强调重男轻女,因此,父子间面孔相似性比父女间面孔相似性对父亲的亲子投资的预测效应更强。本研究采用自我报告的方法测量了212名中学生感知到亲子间面孔相似性、亲子虐待以及人口学变量。结果表明:（1）感知到的亲子间面孔相似性与亲子虐待中的精神虐待存在显著的相关,与身体虐待的相关没有达到显著水平;（2）父母的性别显著地调节着感知到亲子间面孔相似性对精神虐待的预测,具体而言, 父子（女）间面孔相似性显著地预测父亲的精神虐待,而母子（女）间面孔相似性对母亲精神虐待的预测没有达到显著水平;（3）进一步的分析表明,子女的性别显著地调节着感知到父子（女）间面孔相似性对父亲精神虐待的影响,具体而言,父子间面孔相似性显著地预测父亲对儿子的精神虐待,但父女间面孔相似性对父亲对女儿的精神虐待的预测没有达到显著水平。研究结果支持并拓展了父亲身份不确定性假设。     

The Development of Delinquency and Perceived Friendship Quality in Adolescent Best Friendship Dyads

The present study examines both the unique and the combined role of best friends' delinquency and perceived friendship quality in the development of adolescent delinquency. Questionnaire data were gathered from 435 Dutch adolescent best friends (mean age at first wave = 12.97) over a period of 5 years with annual assessments. Results showed that mean levels of delinquency and perceived friendship quality increased over time. Adolescent best friends were highly similar in both mean levels and changes in delinquency over time. For boys, similarity in mean level delinquency between best friends was higher than for girls. In addition, only for boys, friends' delinquency is associated with increases in adolescent delinquency over time, and adolescents' delinquency is associated with increases in friends' delinquency over time. No bidirectional longitudinal associations were found between perceived friendship quality and adolescent delinquency. No interaction effects between friendship quality and friends' delinquency on adolescent delinquency were found. Thus, findings were more in support of the differential association theory than of the social control theory.     

Advantages of Flexible over Traditional Benefits: A Procedural Justice Explanation

This study investigates the relationship between employee benefits plans and employees’ attitudes towards their benefits and the organization. In addition, this study examines the mediating role of perceived procedural justice (decision and process controls) to explain why the provision of benefits affects such attitudes. From a matched sample of two hotels, one offering fixed benefits and the other offering flexible benefits, the results showed that employees’ had higher levels of satisfaction with flexible benefits because of greater decision control in choosing the benefits they desired. Contrary to predictions, employees’ process control in flexible benefits plans had no significant effects on benefits satisfaction. Also, employees did not significantly perceive that their benefits had greater value when they were allowed to choose the benefits that they desired. Employees who were satisfied with their flexible benefits were more committed to their organizations and had lower intentions to quit.     

How does dominance rank status affect individual and social learning performance in the dog (<Emphasis Type="Italic">Canis familiaris</Emphasis>)?

Dogs can learn effectively to detour around a V-shaped fence after observing a demonstration from either an unfamiliar human or dog demonstrator. We found earlier that there is substantial individual variation between the dogs’ performance, even when using the same experimental conditions. Here, we investigate if the subjects’ relative dominance rank with other dogs had an effect on their social learning performance. On the basis of the owners’ answers to a questionnaire, subjects from multi-dog homes were sorted into groups of dominant and subordinate dogs. In Experiment 1, dominant and subordinate dogs were tested without demonstration and we did not find any difference between the groups—they had similarly low detour performances on their own. In Experiment 2 and 3, dogs from single dog and multi-dog households were tested in the detour task with demonstration by an unfamiliar dog, or human, respectively. The results showed that social learning performance of the single dogs fell between the dominant and subordinate multi-dogs with both dog and human demonstration. Subordinate dogs displayed significantly better performance after having observed a dog demonstrator in comparison to dominant dogs. In contrast, the performance of dominant and subordinate dogs was almost similar, when they observed a human demonstrator. These results suggest that perceived dominance rank in its own group has a strong effect on social learning in dogs, but this effect seems to depend also on the demonstrator species. This finding reveals an intricate organization of the social structure in multi-dog households, which can contribute to individual differences existing among dogs.

Perceived control,nature of risk information and risk taking. An experimental test of a simple taxonomy of uncertainty

Uncertainty may be categorized along two dimensions: (1) the nature of probabilistic information (i.e. frequency information, about the outcomes of similar situations in the past, versus process information, about the way(s) in which a future loss might occur), and (2) the degree of personal control (i.e. the extent to which an activity's outcomes depend on internal factors (e.g. knowledge, skills) versus external (e.g. chance) factors). The effects of variations in both dimensions on people's risk-taking tendency were experimentally studied. In a computerized task, subjects had to stop a fast-moving symbol before it passed a target line. Success yielded a financial gain, failure led them into a ‘penalty task’ with the possibility of a considerable loss. On each trial subjects chose among 10 risk levels (varying symbol speeds): low levels resulted in small but almost sure gains, high levels yielded larger but less probable gains. Across subgroups of subjects, three penalty task characteristics were varied: (1) the actual loss probability, (2) the external versus internal determination of outcomes, and (3) the available risk information. Major findings were: (a) subjects did not set a lower risk level, but they did appear to be more attentive (i.e. they failed fewer trials) when the actual loss probability was lower; (b) internal outcome determination resulted in more failed trials (lesser caution); (c) subjects ignored frequency information, but were sensitive to process information. Results are discussed in terms of effort allocation for controlling risk during task performance.     

Academic achievement and popularity in low-socioeconomic status black children

The literature suggests that popularity may have different correlates depending on the ethnic, racial, and/or socioeconomic characteristics of the peer group. This study therefore investigated the relationship between peer popularity and academic achievement in low-socioeconomic status urban black children, a population in which this relationship had not previously been examined. Two hundred ninety-six children in grades 4, 6, and 8 completed three sociometric rating scales, indicating the popularity of each of their same-sex classmates as a workmate, playmate, and best friend. These ratings were subjected to a multivariate analysis of variance in which gender and academic achievement (high vs. low achievement test scores) were factors. Consistent with previous research, high achievement was associated with greater popularity as a workmate for an academic task at all three grade levels examined. Popularity as a playmate and as a best friend, however, was inversely related to achievement among fourth graders and unrelated to achievement among eighth graders. These findings suggest that, although high achievement may be recognized for its adaptive value in a work-related context, it may actually be something of a social liability among younger children choosing partners for social and athletic activities. The results support a conceptualization of popularity as a multidimensional construct and highlight the importance of the use of multiple measures.The authors express their appreciation to the children, parents, and staff of the Orleans Parish Schools for their cooperation and participation in the study and to Rex Forehand and Ben Lahey for helpful comments on the design and analysis.
