Job Characteristics and Biases in Subordinates' Appraisals of Managers

This article develops a general model relating job characteristics to biases in the perception of managers' abilities. A 2 x 2 x 2 between-subjects design was used to vary managerial task complexity, subordinate task complexity, and managers' rates of giving orders. The subjects were 216 upper-level undergraduate students who were randomly assigned to 72 three-person groups. Relative, but not absolute, levels of task complexity biased subordinates' evaluations of managers. This finding is consistent with equity theory and with leadership theories that emphasize the relative contributions of leaders and group members. Procedures that increased order-giving increased subordinates' appraisals of managers when managers performed either relatively more or relatively less complex work than did subordinates, but had no effect under equal complexity conditions. The results are discussed in terms of leader-member exchange theories and contingency theories of leadership (Dienesch & Liden, 1986; Fiedler & Chemers, 1984; Graen, Novak, & Sommerkamp, 1982; Kerr & Jermier, 1978).     

Pitching and clutch hitting in Major League Baseball: What 109 years of statistics reveal

ObjectivesTheory on performance under pressure in sport has proposed that an athlete may be disrupted psychologically when distracted, or when explicitly monitoring too much the skills involved (Beilock & Carr, 2001; Masters, 1992). Research has also suggested that the extent to which an athlete allows pressure to impact performance may be greater for skills of increased complexity, such as hitting a baseball (Kinrade, Jackson, Ashford, & Bishop, 2010; Masters, Polman, & Hammond, 1993). Accordingly, hypotheses for the current study were that baseball hitters would be more susceptible to pressure-induced performance changes than pitchers, whose skills are less based in hand-eye coordination.Design & methodAn archival design was employed, accounting for 109 years of historical baseball data at both the team and individual levels.ResultsIn line with hypotheses, for players with a minimum of 10 postseason innings pitched in a single year (n = 835) pitching statistics were significantly correlated from regular season (less pressure) to postseason (more pressure). For those with a minimum of 20 postseason at bats in a year (n = 1731), hitting statistics were similarly correlated from season to postseason; overall, however, the weakest such relationship was batting average. For teams (n = 370), regular season pitching was expected to be the best predictor of postseason success rates; this hypothesis was supported, but only for the most recent era of baseball history (1995–2011).ConclusionsThe data imply that, while hitting should not be wholly neglected, a successful, clutch baseball team should be built primarily around pitching.     

Evaluating Small Sample Approaches for Model Test Statistics in Structural Equation Modeling

Through Monte Carlo simulation, small sample methods for evaluating overall data-model fit in structural equation modeling were explored. Type I error behavior and power were examined using maximum likelihood (ML), Satorra-Bentler scaled and adjusted (SB; Satorra & Bentler, 1988, 1994), residual-based (Browne, 1984), and asymptotically distribution free (ADF; Browne, 1982, 1984) test statistics. To accommodate small sample sizes the ML and SB statistics were adjusted using a k-factor correction (Bartlett, 1950); the residual-based and ADF statistics were corrected using modified x² and F statistics (Yuan & Bentler, 1998, 1999). Design characteristics include model type and complexity, ratio of sample size to number of estimated parameters, and distributional form. The k-factor-corrected SB scaled test statistic was especially stable at small sample sizes with both normal and nonnormal data. Methodologists are encouraged to investigate its behavior under a wider variety of models and distributional forms.     

Increasing Behavioral Skills and Level of Understanding in Adults: A Brief Method Integrating Dennison's Brain Gym & #x00AE; Balance with Piaget's Reflective Processes

A single session intervention was given individually to 4 adults in order to assist them in achieving their personal goals by improving their behavioral skills for achieving the goals and their conceptual understanding of & #x201C;how to & #x201D; attain these goals. The method was based on a brain-ability analysis of understanding & #x201C;conservation & #x201D; on Jean Piaget's conservation tasks combined with Paul and Gail Dennison's Brain Gym & #x201C;balance & #x201D; procedure. My & #x201C;whole brain understanding & #x201D; model (C. A. Wolfsont, 1999, 2000) and M. L. Commons et al.'s Hierarchical Complexity Scoring System manual were used to analyze the verbal protocols (M. L. Commons et al., 1992; Commons, Danaher, & Meaney, 2000). Increases were found in the participants' conceptual understanding and in the complexity of their performance.     

Integration of internal and external facial features in 8- to 10-year-old children and adults

Investigation of whole-part and composite effects in 4- to 6-year-old children gave rise to claims that face perception is fully mature within the first decade of life (Crookes & McKone, 2009). However, only internal features were tested, and the role of external features was not addressed, although external features are highly relevant for holistic face perception (Sinha & Poggio, 1996; Axelrod & Yovel, 2010, 2011). In this study, 8- to 10-year-old children and adults performed a same–different matching task with faces and watches. In this task participants attended to either internal or external features. Holistic face perception was tested using a congruency paradigm, in which face and non-face stimuli either agreed or disagreed in both features (congruent contexts) or just in the attended ones (incongruent contexts). In both age groups, pronounced context congruency and inversion effects were found for faces, but not for watches. These findings indicate holistic feature integration for faces. While inversion effects were highly similar in both age groups, context congruency effects were stronger for children. Moreover, children's face matching performance was generally better when attending to external compared to internal features. Adults tended to perform better when attending to internal features. Our results indicate that both adults and 8- to 10-year-old children integrate external and internal facial features into holistic face representations. However, in children's face representations external features are much more relevant. These findings suggest that face perception is holistic but still not adult-like at the end of the first decade of life.     

The importance of feature distribution and correlation for simulating 3 to 4-month-old infants' visual categorization processes

Mareschal, French, and Quinn (2000) and Mareschal, Quinn, and French (2002) have proposed a connectionist model of visual categorization in 3- to 4-month-old infants that simulates and predicts previously unexplained behavioural effects such as the asymmetric categorization effect (French, Mareschal, Mermillod, & Quinn, 2004). In the current paper, we show that the model's ability to simulate the asymmetry depends on the correlational structure of the stimuli. These results are important given that adults (Anderson & Fincham, 1996) as well as infants (Younger & Cohen, 1986) are able to rely on correlation information to perform visual categorization. At a behavioural level, the current paper suggests that pure bottom-up processes, based on the correlational structure of the categories, could explain the disappearance of the asymmetry in older 10-month-old infants (Furrer & Younger, 2005). Moreover, our results also raise new challenges for visual categorization models that attempt to simulate the shift from asymmetric categorization in 3- to 4-month-old to symmetric categorization in 10-month-old infants (Shultz & Cohen, 2004; Westermann & Mareschal, 2004, 2012).     

The social behavior and reputation of the attributionally complex

Attributional complexity (AC, [Fletcher, G. J. O., Danilovics, P., Fernandez, G., Peterson, D., & Reeder, G. D. (1986). Attributional complexity: An individual differences measure. Journal of Personality and Social Psychology, 51, 875–884]) is a construct designed to describe individual differences in the motivation and preference for complex attributions for behavior. Scores on the Attributional Complexity Scale (ACS) have been found to be related to a lesser propensity to error and greater accuracy in social judgment. However, little is known concerning how people who score higher on this scale (the attributionally complex) actually behave or are viewed by others. Participants (n = 178) completed the ACS, their behavior as videotaped during a social interaction was rated by four observers, and they were described by two acquaintances along numerous personality characteristics. Behavior of individuals higher in AC was directly observed to be relatively open, positive, expressive, and socially skilled. Although AC was unrelated to academic achievement or SAT scores, those higher in AC tended to be described by peers as having social wisdom, thoughtfulness, empathy, and openness. The behaviors and personality characteristics associated with AC likely contribute to good social judgment.     

Perception of ensemble statistics requires attention

To overcome inherent limitations in perceptual bandwidth, many aspects of the visual world are represented as summary statistics (e.g., average size, orientation, or density of objects). Here, we investigated the relationship between summary (ensemble) statistics and visual attention. Recently, it was claimed that one ensemble statistic in particular, color diversity, can be perceived without focal attention. However, a broader debate exists over the attentional requirements of conscious perception, and it is possible that some form of attention is necessary for ensemble perception. To test this idea, we employed a modified inattentional blindness paradigm and found that multiple types of summary statistics (color and size) often go unnoticed without attention. In addition, we found attentional costs in dual-task situations, further implicating a role for attention in statistical perception. Overall, we conclude that while visual ensembles may be processed efficiently, some amount of attention is necessary for conscious perception of ensemble statistics.     

Follow-up of a cross-national comparison on flashbulb and event memory for the September 11th attacks

Flashbulb memories are defined as vivid and long-lasting memories for the reception context of an important public event (Brown & Kulik, 1977). They are supposed to be triggered by both emotional reactions to the original event and rehearsal processes (Brown & Kulik, 1977; Finkenauer, Luminet, Gisle, El-Ahmadi, van der Linden, & Philippot, 1998; Neisser & Harsch, 1992). A test-retest design (21 vs 524 days after the event on average) was employed to assess flashbulb memory and event memory for the September 11th attacks and the impact of their emotional and rehearsal predictors in a sample of 985 respondents coming from six countries (i.e., Belgium, Italy, the Netherlands, Romania, Japan, and the USA). Results showed that national membership had a significant impact on event memory, and the emotional and rehearsal variables, but flashbulb memories for the September 11th attacks were found to be high and consistent across different countries. The implications of these findings for the debate about the nature and maintenance of flashbulb memories are discussed.     

Early Communications in the War Against Terrorism: An Integrative Complexity Analysis

Integrative complexity reflects the degree to which the source of a communication perceives several dimensions and points of view relevant to the topic (differentiation) and the degree to which such characteristics are seen as related to each other (integration). During international crises, bilateral decreases in the integrative complexity of communications frequently precede the outbreak of war; a unilateral decrease reliably precedes surprise strategic attacks. In the current study, complexity was scored in the messages of selected leaders from before to approximately a month after the terrorist attacks of 11 September 2001. Even this limited database replicated some of the complexity patterns found previously, as well as showing some novel characteristics. This was the first application of the method to hostilities other than inter–nation or civil wars.     

Stimulus complexity and prospective timing: clues for a parallel process model of time perception

Whereas many studies have considered the role of attention in prospective timing, fewer have established relations between movement complexity and prospective timing. The present study aims at assessing to what extent motion complexity interferes with prospective timing and at delineating a neuropsychophysical plausible model. We have thus designed a visual paradigm presenting stimuli in sequential pairs (reference comparison interval). Stimuli are motionless or moving according to different complexities, and stimulus complexities are intermixed within each pair. To prevent a possible attention-sharing effect, no concurrent task was required. Our study suggests that movement complexity is a key component of duration perception, and that the relative judgement of durations depends on spatio-temporal features of stimuli. In particular, it shows that movement complexity can bias subjects’ perception and performance, and that subjects detect that comparison intervals are longer than reference before their end. In the discussion, we advocate that the classical internal clock model cannot easily account for our results. Consequently, we propose a model for time perception, based on a parallel processing between comparison interval perception and the reconstruction of the reference duration.     

Using cluster analysis to test the cultural theory of risk perception

The purpose of the present investigation was to examine if different groups of individuals with similarities in personality and cultural characteristics perceive transport risks differently. The respondents were a representative sample of the Norwegians public (n = 1687). Cluster analysis [Everitt, B. S., Landau, S., & Leese, M. (2001). Cluster analysis. London: Arnold] was applied to identify the groups. There were significant differences in transport risk perception between members of different clusters. However, members with different worldviews did not perceive risk according to the patterns described by cultural theory [Douglas, M., & Wildavsky, A. (1982). Risk and culture. Berkely, Los Angeles, London: University of California Press] and the relations between culture and risk perception seemed somewhat sporadic and unsystematic. Hence the conclusion that there are other factors more important to transport risk perception than the included cultural- and personality characteristics, was supported.     

Career construction in French apprenticeship programs: An exploration of the role of gender in the tutorship

In France, the private sector has increasingly over the last 20 years developed apprenticeship programs (Aeberhardt, Crusson, & Pommier, 2011) in Higher Education. One reason for this development is that young people who prepare for a diploma through apprenticeship programs achieve professional integration in the working world more quickly (Arrighi & Joseph, 2005). However, 17% of young people drop out before the end of their work contract, partly because they consider the work environment to be unsatisfactory or the work too difficult (Cart, ToutinTrelcat, & Henguelle, 2010). In the workplace, apprentices receive the guidance of a professional, the tutor. This research aims to analyze the role of tutor gender on apprentices' perception of their career and intention to quit or stay in the professional sector. The general hypothesis of the research is that tutors have a key role on the career construction of apprentices. Semi-structured interviews have been conducted with apprentices in Higher Education on their relationships with their male or female tutor in the company. The findings underline the role of both tutors' and apprentices' gender and of the particular labor division in the workplace.     

Information‐Theoretic Measures Predict the Human Judgment of Rhythm Complexity

To formalize the human judgment of rhythm complexity, we used five measures from information theory and algorithmic complexity to measure the complexity of 48 artificially generated rhythmic sequences. We compared these measurements to human prediction accuracy and easiness judgments obtained from a listening experiment, in which 32 participants guessed the last beat of each sequence. We also investigated the modulating effects of musical expertise and general pattern identification ability. Entropy rate and Kolmogorov complexity were correlated with prediction accuracy, and highly correlated with easiness judgments. A logistic regression showed main effects of musical training, entropy rate, and Kolmogorov complexity, and an interaction between musical training and both entropy rate and Kolmogorov complexity. These results indicate that information‐theoretic concepts capture some salient features of the human judgment of rhythm complexity, and they confirm the influence of musical expertise on complexity judgments.     

Categorical invariance and structural complexity in human concept learning

An alternative account of human concept learning based on an invariance measure of the categorical stimulus is proposed. The categorical invariance model (CIM) characterizes the degree of structural complexity of a Boolean category as a function of its inherent degree of invariance and its cardinality or size. To do this we introduce a mathematical framework based on the notion of a Boolean differential operator on Boolean categories that generates the degrees of invariance (i.e., logical manifold) of the category in respect to its dimensions. Using this framework, we propose that the structural complexity of a Boolean category is indirectly proportional to its degree of categorical invariance and directly proportional to its cardinality or size. Consequently, complexity and invariance notions are formally unified to account for concept learning difficulty. Beyond developing the above unifying mathematical framework, the CIM is significant in that: (1) it precisely predicts the key learning difficulty ordering of the SHJ [Shepard, R. N., Hovland, C. L., & Jenkins, H. M. (1961). Learning and memorization of classifications. Psychological Monographs: General and Applied, 75(13), 1-42] Boolean category types consisting of three binary dimensions and four positive examples; (2) it is, in general, a good quantitative predictor of the degree of learning difficulty of a large class of categories (in particular, the 41 category types studied by Feldman [Feldman, J. (2000). Minimization of Boolean complexity in human concept learning. Nature, 407, 630-633]); (3) it is, in general, a good quantitative predictor of parity effects for this large class of categories; (4) it does all of the above without free parameters; and (5) it is cognitively plausible (e.g., cognitively tractable).     

Perceptual visual grouping under inattention: electrophysiological functional imaging

Two types of perceptual visual grouping, differing in complexity of shape formation, were examined under inattention. Fourteen participants performed a similarity judgment task concerning two successive briefly presented central targets surrounded by task-irrelevant simple and complex grouping patterns. Event-related potentials (ERPs) were recorded from 22 scalp electrodes and source current density estimations were conducted for the net response to the task-irrelevant background patterns, using low-resolution electromagnetic tomography (LORETA). Although participants’ subjective reports indicated that neither type of organization induced awareness, electrophysiological results showed they both evoked significant activation in occipital, parieto-temporal and frontal brain areas. Behavioral results demonstrated that only grouping of the simple pattern arose under inattention. In contrast to the complex pattern, the processing of the simple pattern was associated with an initially longer latency and higher activation beginning at 130 ms. These results support the distinction of grouping patterns differing in complexity of shape formation.     

Unconscious perception at the objective detection threshold exists

Does unconscious perception at the objective detection threshold (ODT) exist? In this reply, formal meta-analyses of previously narratively reviewed evidence (Snodgrass, Bernat, & Shevrin, 2004) provide strong evidence for large, reliable unconscious perceptual effects, and further strengthen previous conclusions for their ODT status. These meta-analyses dispel general concerns that ODT effects are small, unreliable, or susceptible to file drawer concerns (cf. Reingold, 2004). Furthermore, the specific objections (Holender & Duscherer, 2004) to individual ODT effects are refuted, and objections to our proposed solutions to the exhaustiveness, exclusiveness, and null sensitivity problems (Haase & Fisk, 2004; Reingold, 2004) are shown to be inapplicable, contradicted by the available evidence, or both. Accordingly, the strong evidence for ODT effects, taken together with the nonmonotonic relationship, contradicts the single-process conscious perception model (e.g., Holender & Duscherer, 2004) and provides stronger evidence for unconscious perception than hitherto available.     

Revisiting the metacontrast dissociation: Comparing sensitivity across different measures and tasks

In the metacontrast dissociation procedure, presenting a masked shape prime prior to a visible shape target leads to reaction-time effects of the prime in an indirect measure, although participants cannot consciously detect prime shapes in a direct measure (Klotz & Neumann, 1999 Klotz, W. and Neumann, O. 1999. Motor activation without conscious discrimination in metacontrast masking. Journal of Experimental Psychology: Human Perception and Performance, 25: 976–992.  [Google Scholar]). This has been taken as evidence for the processing of unconscious input. The results of the present metacontrast dissociation study indicate that although participants are unable to consciously report the shape of the prime, they can consciously perceive motion between masked primes and visible targets in a hybrid direct/indirect measure (Experiments 1 and 3). This indicates that former tests did not provide an exhaustive measure for residual conscious perception of the prime in the metacontrast dissociation procedure. Further tests, however, reveal that residual motion perception cannot account for performance in the indirect measure (Experiments 2 and 3). Although the results thus leave the conception of processing of unconscious input intact, they may prompt a revision of its criteria.     

Phoneme monitoring in silent naming and perception in adults who stutter

The present study investigated phonological encoding skills in persons who stutter (PWS). Participants were 10 PWS (M = 31.8 years, S.D. = 5.9) matched for age, gender, and handedness with 12 persons who do not stutter (PNS) (M = 24.3 years, S.D. = 4.3). The groups were compared in a phoneme monitoring task performed during silent picture naming. The phonological complexity of the target items in the task was varied such that participants monitored either compound words or noun phrases. Performance in this task was compared to phoneme monitoring performed on aurally presented target words to investigate whether any differences observed in silent naming were also evident in perception. Analysis of the response time data, in milliseconds, indicated that PWS were significantly slower as compared to PNS in phoneme monitoring during silent naming; group differences were not obtained in the perception task. The groups were also comparable in the response time to phoneme monitoring within compound words and noun phrases in both silent naming and perception. The findings suggested that PWS were slower in the encoding of segmental, phonological units during silent naming. Furthermore, absence of such differences in perception ruled out a general monitoring deficit in PWS. Findings are interpreted within the context of the psycholinguistic theories of stuttering that postulate phonological encoding and/or monitoring as a causal variable in stuttering.

Educational objectives: As a result of this activity, the participant should: (1) describe relevant literature on phonological encoding skills in children and adults who stutter, (2) identify paradigms that can be used to investigate phonological processing in PWS, and (3) discuss the role of phonological encoding in speech production.
