Personality has minor effects on panel attrition

In light of the recent interest in using longitudinal panel data to study personality development, it is important to know if personality traits are related to panel attrition. We analyse the effects of personality on panel drop-out separately for an ‘older’ subsample (started in 1984), a relatively ‘young’ subsample (started in 2000), and a ‘new’ subsample (started in 2009) of the German Socio-Economic Panel (SOEP) study. We found that openness slightly decreases the probability of panel drop-out in all three samples. For the ‘older’ subsample only, we found a small negative effect of agreeableness on panel drop-out. We control for age, sex, education, migration background, and the number of inhabitants in the region of the respondents.     

Quitters would not prosper: Examining the relationship between online assessment performance and assessment attrition behavior

Hiring managers are often hesitant to implement online assessments over concerns that higher‐quality candidates are more likely to quit lengthy assessment batteries than lower‐quality candidates. In this paper, we present the results of two studies that collectively challenge this assumption. In Study 1, data from 327,517 job‐seekers spanning eight hiring contexts showed that assessment performance was negatively associated with subsequent assessment attrition behavior. In Study 2, we replicated this pattern of effects in two additional samples comprising 1,844,604 applicants for hourly associate positions, and 18,937 applicants for nursing positions. Collectively, these findings suggest that some degree of attrition may ultimately benefit, rather than harm, organizations using prehire assessments.     

Sampling Bias and Other Methodological Threats to the Validity of Health Survey Research

Data from a longitudinal occupational health survey of professional fire fighters were used to explore the potential impact of two types of methodological bias: sample selection and reactivity. No significant differences on demographic variables were observed between the group who first responded after a within-study change in survey administration format (Delayed) and respondents who had completed surveys since the study's inception (Initial). However, statistically significant differences in the study's 26 outcome measures provided some evidence that between-group differences did exist and that an administration format type of response bias was also potentially present. The effect sizes associated with the 37 observed significant differences ranged from small to medium. These results provide a context for a reexamination of standard techniques for the identification and interpretation of survey research biases. Methods are suggested to strengthen tests for selection bias and to minimize the impact of response biases.     

Differential attrition in health behaviour change trials: A systematic review and meta-analysis

Objective: Attrition is a common problem in health behaviour change (HBC) trials. When the degree of attrition differs between treatment conditions, then this is called differential attrition and is regarded as a major threat to internal validity. The primary research question of this study was: how often and to what degree does differential attrition occur in HBC trials?

Design: A systematic review and meta-analysis of a random selection of HBC trials (k = 60). We meta-analysed the relative attrition rates using a random-effects model and examined the relationship between the relative attrition rates and the potential moderators: the amount of human contact in delivery and the intensity of the intervention/control condition, the type of control condition, and the follow-up intensity and duration.

Main outcome measures: Relative attrition rates.

Results: The average attrition rate was 18% (SD = .15; M = .15) in the intervention and 17% (SD = .13; M = .13) in the control conditions. The estimated average relative attrition rate was 1.10 (95% CI: 1.01–1.20, p = .02), suggesting an overall higher attrition rate of 10% in the intervention conditions. This relative attrition rate was not related to any of the potential moderators.

Conclusion: There is indication of a slightly higher amount of attrition on average in the intervention conditions of HBC trials.     

The influence of cognitive ability and instructional set on causal conditional inference

We report a large study in which participants are invited to draw inferences from causal conditional sentences with varying degrees of believability. General intelligence was measured, and participants were split into groups of high and low ability. Under strict deductive-reasoning instructions, it was observed that higher ability participants were significantly less influenced by prior belief than were those of lower ability. This effect disappeared, however, when pragmatic reasoning instructions were employed in a separate group. These findings are in accord with dual-process theories of reasoning. We also took detailed measures of beliefs in the conditional sentences used for the reasoning tasks. Statistical modelling showed that it is not belief in the conditional statement per se that is the causal factor, but rather correlates of it. Two different models of belief-based reasoning were found to fit the data according to the kind of instructions and the type of inference under consideration.     

The effects of biasing information on behavioral observations and rating scales

The effects of biasing information on behavioral observations and rating scales were studied. Fortyone undergraduate students trained in making reliable behavioral observations were given differential expectations concerning the activity level of a target child. They then viewed videotape recordings of that child and tallied frequency counts of six behavioral categories simultaneously. In addition, subjects completed postexperimental rating scales composed of specific, identifiable behaviors in regard to the target child. Results indicated that, for the most part, neither the behavioral observations nor the rating scales were significantly affected by the biasing information. It is suggested that rating scales constructed of items as discrete and readily identifiable as those of behavioral observation measures may prove resistant to biasing effects.This study is based in part on a thesis submitted by the second author to Case Western Reserve University in partial fulfillment of the requirements for the master of arts degree in psychology. The authors express their appreciation to the Claremont Unified School District, Claremont, California, for their assistance in the production of the videotape and to the Instructional Support Center at Case Western Reserve University for their co-operation in providing research space. Special thanks are given to Thomas Hyde for his advice and assistance throughout the study.     

The De‐biasing Effect of Incidental Anger on Other‐provided Anchors

The current research investigates the effect of incidental anger on anchoring bias. We hypothesized that feeling angry will make people less influenced by other‐provided anchors because of the moving against action tendency associated with anger. That is, individuals in an angry state will be likely to perceive a given anchor as a viable target for their desire to attack and actively seek out anchor‐inconsistent information, thereby committing less anchoring bias. To examine our hypothesis, in Study 1, we manipulated emotions using film clips and administered a general knowledge task with other‐provided anchors. As predicted, participants in the anger condition showed less anchoring bias to the other‐provided anchors than those in the sad or neutral condition. Study 2 replicated the finding with a different emotion manipulation technique and different anchoring questions. More important, consistent with the moving against action tendency explanation, we also found that people in an angry state committed more anchoring bias for self‐generated anchors, compared with people in a sad or neutral state.

Experimental studies of sequential selection and assignment with relative ranks

We study a class of sequential selection and assignment problems in which a decision maker (DM) must sequentially assign applicants to positions with the objective of minimizing expected cost. In modeling this class of problems, we assume that on each period the DM is only informed of the rank of the present applicant relative to the applicants that she previously observed and assigned. We first present the optimal decision policy that we subsequently use as a normative benchmark, and then report results from three experiments designed to study sequential assignment behavior. In comparing the aggregate results from all three experiments to the optimal decision policy, we identify a systematic bias, called the middleness bias, to over‐assign applicants to intermediate positions. The results also reveal a strong bias for early applicants to be over‐assigned to important positions. Copyright © 2006 John Wiley & Sons, Ltd.     

A general linear model for estimating effect size in the presence of publication bias

When the process of publication favors studies with smallp-values, and hence large effect estimates, combined estimates from many studies may be biased. This paper describes a model for estimation of effect size when there is selection based on one-tailedp-values. The model employs the method of maximum likelihood in the context of a mixed (fixed and random) effects general linear model for effect sizes. It offers a test for the presence of publication bias, and corrected estimates of the parameters of the linear model for effect magnitude. The model is illustrated using a well-known data set on the benefits of psychotherapy.Authors' note: The contributions of the authors are considered equal, and the order of authorship was chosen to be reverse-alphabetical.     

Modality pairing effects and the response selection bottleneck

The present experiment examined the effects of input/output modality pairings on dual-task performance using the psychological refractory period (PRP) procedure. Four groups of participants performed two tasks composed of the same sets of inputs (visual and auditory) and the same sets of outputs (manual and vocal), but with different input/output modality pairings. Whereas modality pairings had only small effects on single-task reaction times, they had large effects on dual-task reaction times. The modality pairing effect cannot stem from differences in the difficulty of stimulus classification or response execution, because these task demands were the same across groups. The effect also does not appear to result from changes in stimulus-response compatibility. The present findings suggest dual-task interference arises not only from postponement of central operations (due to a central bottleneck), but also from a slowing of central operations whose magnitude is sensitive to the input/output modality pairings.     

Intelligence and negation biases on the Conditional Inference Task: A dual-processes analysis

We examined a large set of conditional inference data compiled from several previous studies and asked three questions: How is normative performance related to intelligence? Does negative conclusion bias stem from Type 1 or Type 2 processing? Does implicit negation bias stem from Type 1 or Type 2 processing? Our analysis demonstrated that rejecting denial of the antecedent and affirmation of the consequent inferences was positively correlated with intelligence, while endorsing modus tollens inferences was not; that the occurrence of negative conclusion bias was related to the extent of Type 2 processing; and that the occurrence of implicit negation bias was not related to the extent of Type 2 processing. We conclude that negative conclusion bias is, at least in part, a product of Type 2 processing, while implicit negation bias is not.     

Should research experience be used for selection into graduate school: A discussion and meta‐analytic synthesis of the available evidence

Prior research experience is widely considered by graduate school admissions committees in the United States of America. Here, we use meta‐analytic methods and data from 18 unique samples and a total sample size of 3,525 students to shed light on the validity of prior research experience as a predictor of graduate school performance. Prior research experience was largely unrelated to academic performance (ρ = .01, k = 8, N = 1,419), degree attainment (ρ = .05, k = 3, N = 140), professional/practice performance (ρ = .06, k = 4, N = 1,120), and publication performance (ρ = .11, k = 7, N = 1,094). We also discuss whether consideration of prior research experience may unfairly disadvantage the students with lower levels of SES, students with childcare or eldercare responsibilities, and students from institutions at which research opportunities are limited.     

The evolution of aggression and the level of selection controversy

This paper has two objectives. The first is to examine the “level of selection” controversy in an historical light, particularly as it relates to the evolution and function of aggressive behaviors. Individual and kin selection, on the one hand, and group selection, on the other, are viewed as alternative scientific paradigms for interpreting aggression and other behaviors. It is suggested that the crux of the conflict between these positions involves different ways of explaining altruism. Often, restraints in fighting are tacitly assumed to function first and foremost for the good of the group or species to the detriment of the actor – ie, to be altruistic and to have evolved by group selection. The frequent use of the group level “good for the species” explanations in various disciplines is noted. A second and overlapping objective of this paper is to present evidence against group selection level interpretations and to propose instead that individual level selection and inclusive fitness theory explain better and provide a heuristically more useful way of examining aggressive behavior. Toward these ends, ritualized aggressive behaviors, formerly assumed to exist for species preservation, are reinterpreted along individualistic lines. Next, the concept of inclusive fitness [Hamilton, 1964] is discussed as a theoretical breakthrough which adds support to an individual level approach. In short, the argument is set forth that animals, by and large, do not kill or seriously injure members of their own species because it usually is not in their genetic self-interest to do so; social patterns of interaction such as aggressive encounters should be examined in terms of their effects on the fitness of the individuals engaging in the behaviors before group adaptations are simply assumed. In illustration, data from several animal behavior studies are discussed. Consideration is also given to instances of intraspecific killing and wounding, which in fact occur much more frequently than has been suggested by members of a group selectionist school of thought. Infant killing reported in lions and various primate species is examined and shown to be explicable through individual selection and inclusive fitness theory. It is concluded that this approach represents a more viable theoretical framework for the evolutionary and functional study of both ritualized and other forms of limited animal aggression as well as more violent incidents of intraspecific wounding and killing.     

The effects of negative affectivity on self-reported activity limitations in stroke patients: Testing the Symptom Perception,Disability and Psychosomatic Hypotheses

This study investigated whether Negative Affectivity (NA) causes bias in self-report measures of activity limitations or whether NA has a real, non-artifactual association with activity limitations. The Symptom Perception Hypothesis (NA negatively biases self-reporting), Disability Hypothesis (activity limitations cause NA) and Psychosomatic Hypothesis (NA causes activity limitations) were examined longitudinally using both self-report and objective activity limitations measures. Participants were 101 stroke patients and their caregivers interviewed within two weeks of discharge, six weeks later and six months post-discharge. NA and self-report, proxy-report and observed performance activity (walking) limitations were assessed at each interview. NA was associated with activity limitations across measures. Both the Disability and Psychosomatic Hypotheses were supported: initial NA predicted objective activity limitations at six weeks but, additionally, activity limitations at six weeks predicted NA at six months. These results suggest that NA both affects and is affected by activity limitations and does not simply influence reporting.     

Reducing online application redundancy: Effects on applicant attrition and quality

Job applications have long been a staple of the hiring process and online applications have rapidly become the new norm. The ability to examine applicant attrition—those who start the application but do not finish—and applicant quality are the two benefits of online applications. This study evaluates the effect of reducing application redundancy (not making applicants re‐enter information contained on their resumes) on applicant attrition and quality, with hypotheses derived from signaling theory and economics (cost/benefits). Results demonstrate that reducing redundancy leads to a reduction in applicant attrition across jobs, with the largest magnitude of change found in computer‐related jobs. This reduced attrition does not reduce applicant quality and some evidence suggests that applicant quality may even increase.

Bistability and biasing effects in the perception of ambiguous point-light walkers

The perceptually bistable character of point-light walkers has been examined in three experiments. A point-light figure without explicit depth cues constitutes a perfectly ambiguous stimulus: from all viewpoints, multiple interpretations are possible concerning the depth orientation of the figure. In the first experiment, it is shown that non-lateral views of the walker are indeed interpreted in two orientations, either as facing towards the viewer or as facing away from the viewer, but that the interpretation in which the walker is oriented towards the viewer is reported more frequently. In the second experiment the point-light figure was walking backwards, making the global orientation of the point-light figure opposite to the direction of global motion. The interpretation in which the walker was facing the viewer was again reported more frequently. The robustness of these findings was examined in the final experiment, in which the effects of disambiguating the stimulus by introducing a local depth cue (occlusion) or a more global depth cue (applying perspective projection) were explored.     

The effects of prior expectations and outcome knowledge on polygraph examiners' decisions

The present study deals with the question of whether judgments made by experts working in familiar contexts are affected by prior expectations and beliefs. Two experiments in which prior expectations were manipulated were designed to determine whether and to what extent polygraph examiners are affected by their prior expectations when analyzing and interpreting polygraph charts. Prior expectations affected the examiners' judgments when the polygraph charts did not include clear indications of guilt or innocence, but when the objective physiological evidence included strong indications which clearly contradicted the examiner's expectations, judgments were not affected by these expectations. Theoretical and practical implications of these results are discussed.     

心理距离对自发特质推理的影响

采用错误再认范式,考察了心理距离是否影响个体对他人行为的自发特质推理。实验1采用2（配对类型：图片-可推测的特质词、图片-不可推测的特质词）× 2（空间距离：近、远）的混合设计,要求被试判断特质词是否在前面的行为句中出现过,以探讨自发特质推理形成情况。结果表明,与近空间距离相比,被试对远空间心理距离的行为主体产生了更多的自发特质推理。实验2采用2（配对类型：图片-可推测的特质词、图片-不可推测的特质词）× 2（时间距离：近、远）的混合设计,被试反应与实验1相同。结果发现,与近时间心理距离相比,被试对远时间心理距离的行为主体产生了更多的自发特质推理。实验结果提示远心理距离比近心理距离更利于自发特质推理,并在解释水平理论的框架内对结果进行了讨论。
