Building a cognitive map by assembling multiple path integration systems

Path integration and cognitive mapping are two of the most important mechanisms for navigation. Path integration is a primitive navigation system which computes a homing vector based on an animal’s self-motion estimation, while cognitive map is an advanced spatial representation containing richer spatial information about the environment that is persistent and can be used to guide flexible navigation to multiple locations. Most theories of navigation conceptualize them as two distinctive, independent mechanisms, although the path integration system may provide useful information for the integration of cognitive maps. This paper demonstrates a fundamentally different scenario, where a cognitive map is constructed in three simple steps by assembling multiple path integrators and extending their basic features. The fact that a collection of path integration systems can be turned into a cognitive map suggests the possibility that cognitive maps may have evolved directly from the path integration system.     

Motion influences gaze direction discrimination and disambiguates contradictory luminance cues

In two experiments, we investigated the role of apparent motion in discriminating left/right gaze deviation judgments. We demonstrated that discrimination accuracy and response confidence was significantly higher when the eyes were moved to the left or right, compared to when the eyes were presented in their final shifted position (static images). To dissociate the role of motion signals from luminance signals, gaze stimuli were also presented in reverse contrast. Replicating past studies polarity reversal had a profound and detrimental effect on gaze discrimination in static images, although, intriguingly, while response confidence remained low, participant performance improved as gaze angle increased. In striking contrast to these data, polarity reversal had no negative effect on performance when the eyes were moved. We discuss these findings in the context of a multiple-cue account of gaze perception.     

Collateral Reports and Cross-Informant Agreement about Adult Psychopathology in 14 Societies

To advance international mental health assessment, instruments that have been internationally validated are needed. To this end, we analyzed ratings from 14 societies on the Adult Behavior Checklist (ABCL), a collateral-report form parallel to the Adult Self-Report (ASR; Achenbach and Rescorla 2003) for ages 18 to 59. Both the ABCL and the ASR assess problems, personal strengths, and adaptive functioning. For a sample of 8322 see note below collaterals, we found strong consistency across societies regarding which ABCL problem items tended to obtain relatively low, medium, or high ratings. Most societal effect sizes (ESs) for problem scale scores were small to medium (< 13.9 %), but the ES for the ABCL Personal Strengths scale was 25 %. For most of the same participants (N = 8,302), we analyzed cross-informant agreement between self-reports on the ASR and collateral reports on the ABCL. Cross-informant correlations for problem scale scores averaged .47, with considerable societal variation. Problem score means were higher on the ASR than the ABCL in every society, but the size of the difference varied across societies. Mean item ratings on the ABCL and ASR were highly correlated within every society (mean r = .92), but within-dyad item rating agreement varied widely in every society (mean r = .39). In all societies, non-corroboration of self-reported deviance and of collateral-reported deviance was common. Overall findings indicated considerable similarity but also some important differences in collateral-reported problems and adaptive functioning across 14 societies.     

Good Soldier or Good Actor? Supervisor Accuracy in Distinguishing Between Selfless and Self-Serving OCB Motives

Purpose

In line with findings that organizational citizenship behaviors (OCBs) may be driven by selfless and self-serving motives, we sought to determine supervisor effectiveness in distinguishing good soldiers from good actors.

Design/Methodology/Approach

Employing a sample of 197 supervisor-subordinate dyads, we collected self- and supervisor-reports of employees’ citizenship motives. Dominance analysis was used to determine supervisory accuracy in identifying and distinguishing among subordinates’ motives.

Findings

We found that the relationships between self- and supervisor-reports of corresponding motives were strongest, supporting our hypotheses that supervisors are able to accurately identify their subordinates’ OCB motives and that they are not fooled by good actors.

Implications

Our results address concerns raised in previous research that inaccuracy in supervisor attributions of motives might lead to unfair reward or punishment of their subordinates. In demonstrating their accuracy in identifying their subordinates’ motives, an important implication of our work is that supervisors’ preferences for selfless motives may relate to actual differences in their employees’ contribution to the organization.

Originality/Value

Our study contributes to existing research to more conclusively address the question of supervisors’ bias in their preference for selfless motives. Our results also underscore the importance of accounting for employee motives in research exploring the outcomes of OCBs.

     

Distinguishing CEOs from Top Level Management: A Profile Analysis of Individual Differences,Career Paths and Demographics

Purpose

Identifying the characteristics of chief executive officers (CEOs) has been a longstanding goal in leadership and individual differences research. The purpose of this exploratory study was to consider which individual difference and career path variables differentiate CEOs from other senior managers.

Design/Methodology/Approach

Participants (N = 1152) were UK-based senior managers (n = 1040) and CEOs (n = 112) who completed a self-report measure of the Five Factor Model of personality (NEO-PI-R), a measure of cognitive ability (graduate and management aptitude test), and answered a number of additional questions on their career paths as part of development centres. Analyses comprised inter-individual mean difference tests, intra-individual external profile analysis and logistic regression.

Findings

Results indicated that personality facets of impulsiveness, vulnerability, activity and dutifulness showed the largest mean differences. No significant effects were found for the criterion profile pattern, but significant effects were found for profile level. Of the additional predictors, career path variables were the strongest predictors of CEO status.

Implications

The combination of significant effects across domains of individual differences and career path variables emphasizes the importance of a multivariate approach in the study of leadership, top management teams and career progression.

Originality/Value

The current study combines personality, cognitive ability, demographic and career path variables, and applies intra-individual methodologies to explore the characteristics of the very top level of organisational hierarchy.

     

Examining Ethicality Judgements of Theft Behavior: The Role of Moral Relativism

Purpose

The purpose of this study was to investigate whether situational factors predict ethicality judgments of theft behavior, and whether the effect of situational factors is moderated by moral relativism.

Design/Methodology/Approach

Data were obtained across two laboratory experiments using undergraduate business students attending a Canadian university (n = 372). Student participants viewed a videotaped vignette of an employee informed that he had been caught stealing sales commission. In the vignettes, we manipulated two situational factors: whether or not (a) the theft has monetary consequences for the organization, and (b) similar theft is commonplace within the organization.

Findings

In Experiment 1, both situational factors interacted with moral relativism in the prediction of ratings of unethical conduct. In Experiment 2, using a within-participant research design, we achieved an interaction between the organizational consequences manipulation and moral relativism, although we obtained a considerably stronger effect size for the interaction compared to the first experiment.

Implications

We discuss implications of our findings and suggest avenues for future research. In particular, we consider the possibility that managers may not share a common frame-of-reference when considering the ethicality of theft. This could affect whether and the extent to which theft behavior is reprimanded.

Originality/Value

Our study contributes to research on employee theft, and also adds incrementally to our understanding of how both situational factors and moral relativism jointly influence perceptions of theft behavior.

     

Development and Validation of the Workplace Age Discrimination Scale

Purpose

Workplace age discrimination research is proliferating, but researchers lack a valid measure with which to capture targets’ discriminatory experiences. We developed a measure of perceived workplace age discrimination that assesses overt and covert forms of discrimination and then compared older, middle-aged, and younger workers’ experiences.

Design/Methodology

In Study 1, we developed the Workplace Age Discrimination Scale (WADS) based on older workers’ experiences using a deductive approach, a qualitative study, and two quantitative surveys. In Study 2, we validated the measure among young employees using a qualitative and two quantitative surveys. In Study 3, we tested the WADS among middle-aged workers and tested models of invariance between age groups.

Findings

Participants frequently endorsed covert discriminatory experiences, which the WADS reflects. The WADS contains convergent and discriminant validity, high reliability, and a unidimensional structure across age groups. It demonstrates criterion-related validity among older and younger workers but not middle-aged workers, given their low experiences of age discrimination. Age discrimination frequency follows a U-shaped pattern across age groups.

Implications

Researchers can use the WADS to identify long-term outcomes of age discrimination and to further compare workers’ discriminatory experiences. Practitioners and policymakers can use the measure to develop interventions to ameliorate workplace age discrimination and inform policymaking.

Originality/Value

The WADS is the first validated measure of targets’ perspectives of workplace age discrimination. Our results challenge assumptions that only older workers experience age discrimination (younger workers’ means were highest) and that age discrimination is usually overt in nature (it is often covert).
