Looking versus seeing: Strategies alter eye movements during visual search

Visual search can be made more efficient by adopting a passive cognitive strategy (i.e., letting the target “pop” into mind) rather than by trying to actively guide attention. In the present study, we examined how this strategic benefit is linked to eye movements. Results show that participants using a passive strategy wait longer before beginning to move their eyes and make fewer saccades than do active participants. Moreover, the passive advantage stems from more efficient use of the information in a fixation, rather than from a wider attentional window. Individual difference analyses indicate that strategies also change the way eye movements are related to search success, with a rapid saccade rate predicting success among active participants, and fewer and larger amplitude saccades predicting success among passive participants. A change in mindset, therefore, alters how oculomotor behaviors are harnessed in the service of visual search.     

Beyond resilients,undercontrollers, and overcontrollers? an extension of personality prototype research

Prototypes of personality were investigated in two studies. In study I, clusters of Big‐Five‐based prototypes were examined using a general population sample of 1908 German adults. Convergent evidence suggested the appropriateness of a five‐cluster solution, which corresponds to previously identified temperament based prototypes. In study II, the five‐cluster solution was cross‐validated in a sample of 256 prisoners. Moreover, it was shown that a population‐based approach (using discriminant functions derived from study I) was superior over the traditional sample‐based cluster approach (using Ward followed by k‐means). The authors argue that future typological research can be sufficiently grounded on a five‐prototype conception rather than on a three‐prototype conception, and suggest a new and flexible assignment procedure.

Semisimple Varieties of Modal Algebras

In this paper we show that a variety of modal algebras of finite type is semisimple iff it is discriminator iff it is both weakly transitive and cyclic. This fact has been claimed already in [4] (based on joint work by the two authors) but the proof was fatally flawed. Dedicated to the memory of Willem Johannes Blok     

Effects of management communication, opportunity for learning, and work schedule flexibility on organizational commitment

In the current career climate characterized by change and turbulence, employees may demonstrate limited organizational commitment to their employers. Rousseau (1998) suggests that two key ways to elicit loyalty from employees today are to reinforce perceptions of organizational membership and demonstrate organizational care and support for employees. Based on her conceptual framework, we examined the separate and synergistic effects of three valued aspects of the work environment—management communication, opportunity for learning, and work schedule flexibility—on organizational commitment. With 1770 full-time and 273 part-time workers of a large national retailer, we found that all three variables had positive main effects on organizational commitment. Also, they three-way interacted to affect part-time workers’ organizational commitment. The implications of these findings for research on organizational commitment and on comparisons of full-time and part-time workers are discussed.     

Perceived support for mentoring: A multiple perspectives approach

Two studies were conducted to examine how perceptions of support for mentoring relate to mentoring attitudes and outcomes for both protégés and mentors, over and above established predictors. In study 1, protégés provided information on their perceptions of support for mentoring and mentoring received. As expected, perceived management support for mentoring was positively related to career-related and psychosocial support; and perceived mentor accountability for mentoring was negatively related to mentoring problems. In study 2, we examined mentors’ perceptions of support for mentoring in relation to their willingness to mentor others in the future and the extent to which they viewed their current relationship as complementary. Mentors’ perceptions of management support for mentoring were positively related to their belief that mentoring relationships were mutually beneficial. However, consistent with theories of self-determination, as mentors’ perceptions of their own accountability in the relationship increased their willingness to mentor others in the future decreased. Implications for mentoring theory, future research, and applied practice are discussed.     

A Big Tent of Dark Personality Traits

Researchers have become very interested in socially aversive personality traits in recent years as reflected by the considerable number of publications concerning the Dark Triad of personality (i.e., Machiavellianism, narcissism, and psychopathy). The goal of the present article is to suggest that researchers broaden their view of potentially dark personality features. We provide overviews of two dark personality features that have been largely neglected by psychologists (i.e., spitefulness and greed) and point to the darker aspects of two personality features that have been studied extensively (i.e., perfectionism and dependency). We conclude the article by advocating that researchers consider a broader conceptualization of dark personality features that extends beyond the antagonistic and externalizing features captured by the Dark Triad traits.     

Information‐Theoretic Properties of Auditory Sequences Dynamically Influence Expectation and Memory

A basic function of cognition is to detect regularities in sensory input to facilitate the prediction and recognition of future events. It has been proposed that these implicit expectations arise from an internal predictive coding model, based on knowledge acquired through processes such as statistical learning, but it is unclear how different types of statistical information affect listeners’ memory for auditory stimuli. We used a combination of behavioral and computational methods to investigate memory for non‐linguistic auditory sequences. Participants repeatedly heard tone sequences varying systematically in their information‐theoretic properties. Expectedness ratings of tones were collected during three listening sessions, and a recognition memory test was given after each session. Information‐theoretic measures of sequential predictability significantly influenced listeners’ expectedness ratings, and variations in these properties had a significant impact on memory performance. Predictable sequences yielded increasingly better memory performance with increasing exposure. Computational simulations using a probabilistic model of auditory expectation suggest that listeners dynamically formed a new, and increasingly accurate, implicit cognitive model of the information‐theoretic structure of the sequences throughout the experimental session.
