应急救援团队的个体与团队情境意识：社会网络关系的调节作用

采用地震后建筑物倒塌,被困人员转运的任务情景,以99名消防指挥系大四学员为被试,研究个体情境意识和团队情境意识的关系,以及社会网络关系中的网络密度和结构洞指标在其中的调节作用。结果表明：(1)个体情境意识与团队情境意识不相关,即团队情境意识不是个体情境意识的简单相加;(2)共享情境意识对团队情境意识有负向影响：个体情境意识之间的差异越大,团队情境意识就越高;(3)对于网络密度较大的团队,结构洞对共享情境意识和团队情境意识的关系起到正向调节的作用;(4)对于网络密度较小的团队,结构洞对共享情境意识和团队情境意识的关系起到负向调节的作用。     

A two-part evaluation approach for measuring the usability and user experience of an Augmented Reality-based assistance system to support the temporal coordination of spatially dispersed teams

One key predictor of team performance and productivity is the teams’ ability to coordinate its subtasks as precisely as possible over time. Thereby, the quality of the temporal coordination in teams is highly dependent on several cognitive team skills, like for instance the ability to build a precise and stable mental model of the situation (shared situation awareness) and of the team task process (task state awareness/ TSA). To support these cognitive skills in teams, various methods and trainings already exist. However, considering teams that work de-located, the prerequisites and therefore the requirements for team supportive methods change. This work presents the results of an empirical usability and user experience (UX) study of an interface for an Augmented Reality-based assistance system for spatially dispersed teams, called Ambient Awareness Tool (AAT). The AAT interface consists of graphical information about the teamwork process and aims at enhancing the TSA of the team, thereby supporting its temporal coordination. Within the framework of a participatory design process we conducted a two-part expert-user-study, comprising a laboratory experiment for the evaluation of the interface usability and a follow-up online survey to additionally investigate the UX. By means of the usability scores we first inferred three interface configuration clusters. A subsequent UX evaluation then allowed us to designate the configuration cluster with the highest usability and UX scores. As a result, we defined one interface configuration that will be investigated concerning its actual impact on the temporal coordination of spatially dispersed teams in a further study.     

Tactile spatial acuity differs between fingers: a study comparing two testing paradigms

Tactile spatial acuity (TSA) is a reliable and reproducible measure of somatosensory system function that has been used to study abroad range of subject populations. Although TSA is most often assessed at the fingertip, published studies employing identical stimuli disagree on whether TSA differs between the fingers of neurologically normal subjects. Using a validated grating orientation discrimination task, we determined TSA bilaterally at the index and ring fingers of 16 healthy young adults. Motivated by earlier work, we utilized two stimulus presentation paradigms, the method of constant stimuli (MCS) and a staircase (SC) method. We found that TSA was significantly higher (the discrimination threshold was lower) at the index than at the ring finger, which was consistent with a prior study. Although mean thresholds at both fingers were higher when measured with the SC than with the MCS paradigm, this difference did not reach statistical significance (p = .14). These findings should facilitate both design and interpretation of future studies investigating TSA.     

Team situation awareness within the context of human-autonomy teaming

Effective team communication, a fundamental part of team coordination, is crucial for both effective Team Situation Awareness (TSA) and team performance. In this study, we looked at the role that team interaction (i.e., more specifically team verbal behaviors) played in TSA and team performance in order to better understand Human-Autonomy Teaming (HAT). We first analyzed team verbal behaviors (i.e., pushing and pulling information) across conditions of human-autonomy teams and human-human teams, and then analyzed their relationship with TSA and team performance via Growth Curve Modelling (GCM). Good teamwork involves anticipating the needs of teammates and that means pushing information before it is requested. Therefore, if things are going well, there should be little need for pulling information. In this study’s task, participants were instructed to push information to others, and over time master the specific timing of information sharing to the intended recipient. Findings indicate that pushing information was positively associated with TSA and team performance, and human-autonomy teams had lower levels of both pushing and pulling information than all-human teams. Through this study, we have learned that anticipation of other team member behaviors and information requirements in human-autonomy teams are important for effective TSA and team performance. In order to make HAT more effective in terms of teamwork, we need to develop mechanisms to enhance pushing information within HAT.     

The ideologically objectionable premise model: Predicting biased political judgments on the left and right

This paper introduces the ideologically objectionable premise model (IOPM), which predicts that biased political judgments will emerge on both the political left and right, but only when the premise of a judgment is not ideologically objectionable to the perceiver. The IOPM generates three hypothesized patterns of bias: biases among both those on the left and right, bias only among those on the right, and bias only among those on the left. These hypotheses were tested within the context of the dual process motivational model of ideological attitudes (DPM; Duckitt, 2001), which posits that right-wing authoritarianism (RWA) and social dominance orientation (SDO) are related but distinct ideological attitudes. Across two studies, all three IOPM hypotheses were tested and supported on the RWA ideological attitude dimension, and two of the three IOPM hypotheses were tested and supported on the SDO dimension. These findings indicate that the context of the judgment is an important determinant of whether biases emerge in political judgment.     

Recovering Substantive Factor Loadings in the Presence of Acquiescence Bias: A Comparison of Three Approaches

Researchers are often advised to write balanced scales (containing an equal number of positively and negatively worded items) when measuring psychological attributes. This practice is recommended to control for acquiescence bias (ACQ). However, little advice has been given on what to do with such data if the researcher subsequently wants to evaluate a 1-factor model for the scale. This article compares 3 approaches for dealing with the presence of ACQ bias, which make different assumptions: an ipsatization approach based on the work of Chan and Bentler (CB; 1993), a confirmatory factor analysis (CFA) approach that includes an ACQ factor with equal loadings (Billiet & McClendon, 2000; Mirowsky & Ross, 1991), and an exploratory factor analysis (EFA) approach with a target rotation (Ferrando, Lorenzo-Seva, & Chico, 2003). We also examine the “do nothing” approach which fits the 1-factor model to the data ignoring the presence of ACQ bias. Our main findings are that the CFA method performs best overall and that it is robust to the violation of its assumptions, the EFA and the CB approaches work well when their assumptions are strictly met, and the “do nothing” approach can be surprisingly robust when the ACQ factor is not very strong.     

Measuring recognition memory.

Recent years have seen an expanded interest in recognition memory tasks. This resurgence of interest has also renewed concerns with measurement problems. Comparing 4 models of recognition memory, Snodgrass and Corwin (1988) found that measures of bias from the distribution-free (nonparametric) model were inadequate. However, their analysis was based on bias measures that can be shown a priori to be nonindependent of discrimination. This article traces the history of the nonparametric model and develops a better measure of bias. The consequence of developing this better measure is that the nonparametric model deserves serious consideration.     

The Traditional Regression Model for Measuring Test Bias is Incorrect and Biased Against Minorities

For 25 years psychologists have measured systematic measurement bias in terms of regression lines. According to this traditional approach a test is an unbiased predictor of a criterion for all subgroups if all subgroups have identical Y regression lines (i.e., identical slopes and identical Y intercepts). This paper shows that the traditional model is fundamentally incorrect and identical Y regression lines are not expected to occur with an unbiased test in a testing situation in which one group score lower than another group on both the test and criterion. This is the case even if the test is perfectly reliable. The traditional model for measuring bias actually results in a consistent error or bias against groups which score lower than average on both the test and criterion. In practice this bias operates against minority groups. Tests now thought to be unbiased or even biased in favor of minority groups may in fact be biased against minority groups. A new model of test bias, which is based solely on measurement principles, is briefly introduced. In this model unbiased tests produce groups with identical test-criterion common-factor axes having a slope of S _YC/S _XC and with each axis intersecting the group centroids.     

Using the Criterion-Predictor Factor Model to Compute the Probability of Detecting Prediction Bias with Ordinary Least Squares Regression

The study of prediction bias is important and the last five decades include research studies that examined whether test scores differentially predict academic or employment performance. Previous studies used ordinary least squares (OLS) to assess whether groups differ in intercepts and slopes. This study shows that OLS yields inaccurate inferences for prediction bias hypotheses. This paper builds upon the criterion-predictor factor model by demonstrating the effect of selection, measurement error, and measurement bias on prediction bias studies that use OLS. The range restricted, criterion-predictor factor model is used to compute Type I error and power rates associated with using regression to assess prediction bias hypotheses. In short, OLS is not capable of testing hypotheses about group differences in latent intercepts and slopes. Additionally, a theorem is presented which shows that researchers should not employ hierarchical regression to assess intercept differences with selected samples.     

Determinants of Overconfidence and Miscalibration: The Roles of Random Error and Ecological Structure

Previous authors have attributed findings of overconfidence to psychological bias or to experimental designs unrepresentative of the environment. This paper provides evidence for an alternative explanation. A model is presented in which reported confidence is a function of the validity of information used by the subject, and a random error component. The model predicts greater overconfidence for question sets in which informational cues are less valid. This result corresponds to the well-known hard/easy effect. The model also predicts that unrepresentative design (Gigerenzer, Hoffrage, & Kleinbölting, 1991) is sufficient but not necessary for overconfidence to occur. These predictions are tested, and results provide support for the model. Subjects are overconfident according to usual measures such as calibration, even though on average they report the diagnosticity of informational cues correctly. Furthermore, overconfidence is greater for harder sets of questions, even when those sets are representative of the environment. A post hoc analysis reveals some intriguing individual differences among subjects. Some people appear to have a true psychological bias toward reporting high levelsof confidence, whereas others have a psychological bias in the direction of underconfidence.     

Victimization and Polyvictimization Among Spanish Adolescent Outpatients

This article aimed to analyze lifetime and past-year victimization and polyvictimization experiences in adolescent outpatients from a southern European country. The sample included 149 adolescents (35.6% boys, 64.4% girls), aged 12 to 17 (M = 14.28, SD = 1.45). Experiences of victimization were assessed using the Juvenile Victimization Questionnaire (JVQ; Finkelhor, Hamby, Ormrod, & Turner, 2005). Results showed that 99.3% of those interviewed had experienced at least one type of victimization during their lifetime, and 84.6% reported past-year victimization. Gender and age differences were found. Based on community criteria, the proportion of polyvictims in the sample was 32.2% for lifetime victimization and 20.1% for past-year victimization. When assessing children in the context of outpatient mental health services, it is essential that clinicians explore any history of exposure to violence, as this information is crucial in determining the young person’s therapeutic needs.     

Time Series Analysis in Historiometry: A Comment on Simonton

Time series analysis (TSA) is one of a number of new methods of data analysis appropriate for longitudinal data. Simonton (1998) applied TSA to an analysis of the causal relationship between two types of stress and both the physical and mental health of George III. This innovative application demonstrates both the strengths and weaknesses of time series analysis. Time series is applicable to a unique class of problems, can use information about temporal ordering to make statements about causation, and focuses on patterns of change over time, all strengths of the Simonton study. Time series analysis also suffers from a number of weaknesses, including problems with generalization from a single study, difficulty in obtaining appropriate measures, and problems with accurately identifying the correct model to represent the data. While careful attempts are made to minimize these problems, each is present in the Simonton study, although sometimes in a subtle manner. Changes in how the data could be gathered are suggested that might help to solve some of these problems in future studies. Finally, the advantages and disadvantages of employing alternative methods for analyzing multivariate time series data, including dynamic factor analysis, are discussed.     

Unresolved Childhood Sexual Abuse and Older Adults: Late-Life Vulnerabilities

Several long-term correlates of childhood sexual abuse (CSA) have been identified, including depression, fear, anxiety, guilt, anger, and poor interpersonal functioning (e.g., Browne and Finkelhor, 1986). However, little is know about how CSA survivors fare in old age. This article addresses the impact of unresolved CSA on late-life (emotional, cognitive, and behavioral) functioning. Three case studies of older adults ages 60 and older who were struggling with unresolved CSA are presented. Two observed stressors (loss of social support and declining health) and one developmental task (reminiscence or life-review) appear to be linked to exacerbated vulnerabilities in older survivors. Specifically, because CSA may arrest specific childhood developmental tasks (e.g., ability to form secure attachments, autonomy) or facilitate development of coping strategies that are maladaptive when outside of an abusive environment (e.g., generalized interpersonal distrust, avoidance, dissociation), the survivor may be at risk for developmental vulnerabilities for dysfunction in adulthood. These vulnerabilities may exacerbate unresolved CSA, particularly when the adult encounters stressors or developmental tasks that exceed his or her capacity for adaptive coping. Recommendations for mental health professionals and future research are suggested.     

Family violence: A focus on india

Finkelhor called those interested in raising consciousness regarding family violence to recognize its multifaceted nature, including several types of abuse and victims. This paper identifies the many faces of physical family maltreatment—spousal, child, elder, sibling, filial—in India. Here, traditional norms that condone violence, themes of the sanctity of the family, and patriarchal prerogatives have dominated family relationships and prevented intervention. In recent years, India has been increasingly open about the experiences of battered women, yet it is still loathe to acknowledge intrafamilial violence toward children. Elder abuse, sibling maltreatment, and filial violence in India have yet to come into the awareness of the social services.     

The School Functioning of Individuals with Childhood Experiences of Sexual Abuse: Results and Implications of a South African Study

This study investigated the school functioning of individuals with childhood sexual experiences in South Africa. The nature of the study was qualitative, and employed two data collection strategies: in-depth individual interviews with 22 survivors of child sexual abuse and focus interviews with two groups of teachers. The study revealed that participants' emotional reaction to the abuse affected three broad areas of school functioning: concentration, interest in school-related activities and school adjustment. The intensity of these problems varied across participants. The findings are consistent with Finkelhor and Browne's (1986) traumagenic model, which suggests that the experience of child sexual abuse often results in feelings that interfere with one's cognitive development and emotional orientations to the world and causes trauma by distorting the victim's self concept and worldview.     

Extreme Response Style and the Measurement of Intra-Individual Variability in Affect

Extreme response style (ERS) has the potential to bias the measurement of intra-individual variability in psychological constructs. This paper explores such bias through a multilevel extension of a latent trait model for modeling response styles applied to repeated measures rating scale data. Modeling responses to multi-item scales of positive and negative affect collected from smokers at clinic visits following a smoking cessation attempt revealed considerable ERS bias in the intra-individual sum score variances. In addition, simulation studies suggest the magnitude and direction of bias due to ERS is heavily dependent on the mean affect level, supporting a model-based approach to the study and control of ERS effects. Application of the proposed model-based adjustment is found to improve intra-individual variability as a predictor of smoking cessation.     

A model for realism of confidence judgments: Implications for underconfidence in sensory discrimination

In a recent issue of this journal, Björkman, Juslin, and Winman (1993) presented a model of the calibration of subjective confidence judgments for sensory discrimination which they called “subjective distance theory.” They proposed that there was a robust underconfidence bias in such judgments, that the model predicted such a bias, and that two different models were needed for the calibration of subjective confidence for cognitive judgments and for sensory ones. This paper addresses issues they raised. It points out that they have not presented a new model, but rather a portion of a more general one, the “decision-variable partition model” originally proposed in Ferrell and McGoey (1980). This paper explores properties of the model and shows, contrary to Björkman, Juslin, and Winman’s hypotheses, that the model does not predict under-confidence, that the “hard-easy effect” can be observed with sensory discriminations, and that the model fits not only sensory, but also cognitive judgments.     

THE NEED FOR POWER IN WOMEN WHO WERE SEXUALLY ABUSED AS CHILDREN An Exploratory Study

Ten women who had been sexually abused as children and a matched group of women who had not been sexually abused participated in a preliminary study to explore the hypothesis that feelings of powerlessness and a compensatory need for power continue into adulthood for survivors of childhood sexual abuse. The Picture-Story Exercise (PSE) was used as an indirect assessment technique to determine the level of the need for power (McClelland, 1985; Winter, 1973, 1988). Results indicated that the stories of women with sexual abuse histories revealed a higher need for power and greater fear of power than those of nonabused women. Further content analysis of the PSE revealed that sexual abuse survivors' stories also contained more references to Finkelhor and Browne's (1986) dynamics of powerlessness, traumatic sexualization, betrayal, and stigmatization. These findings suggest important directions for future research as well as areas for therapeutic exploration.     

Secret-Keeping Behaviors in Black and White Children as a Function of Interviewer Race,Racial Identity,and Risk for Abuse

Summary

The tendency for children to keep the secret of child abuse is an important practical impediment to adequate research, prevention, assessment, and treatment. While some studies have established that children will readily keep adult secrets, few have investigated the predictors of ease of disclosure. In this research, race of the interviewer requesting the secret strongly affected disclosure, with Black children particularly showing an unwillingness to disclose a negative secret to a different race interviewer. Children at high risk for sexual abuse (as assessed by the Finkelhor checklist) also were more likely to keep the secret.
