Contextual control of slot-machine gambling: replication and extension

Participants were trained and tested to select stimuli of differing physical quantities in the presence of 2 color contextual cues for more than and less than. Following more than and less than relational training, participants allocated the majority of their responses to the slot machine that shared formal properties of color with the contextual cue for more than, despite the identical payout probabilities of the slot machines.     

Safety in work vehicles: a multilevel study linking safety values and individual predictors to work-related driving crashes

Although work-related driving is associated with high accident rates, limited research has investigated the factors influencing driving crashes in the work setting. This study explored multilevel influences on self-reported crashes in the workplace by surveying a sample of work-related drivers (n = 380), their workgroup supervisors (n = 88), and fleet managers (n = 47). At the driver level of analysis, safety motivation predicted self-reported crashes. In turn, drivers' perceptions of their fleet managers' safety values (but not drivers' perceptions of their supervisors' safety values), their own attitudes, and their own efficacy beliefs predicted motivation to drive safely. Furthermore, the influence of supervisors and fleet managers interacted such that drivers were more motivated to drive safely if they perceived both their supervisor and fleet manager to value safety. This study also explored the cross-level relationships between supervisors' and fleet managers' perceptions of organizational safety values and drivers' perceptions of managerial safety values and found a relationship between fleet managers' perceptions of organizational safety values and drivers' perceptions of fleet managers' safety values. These results illustrate that perceptions of workplace safety values are transmitted across levels of the organization.     

Prejudice as Self‐Control Failure1

Research has suggested that whereas stereotypical attitudes may be automatically activated, the response to these stereotypes can be controlled. Anything that interferes with self‐control may result in more biased behavior. The ego strength model hypothesizes that after exerting self‐control, subsequent self‐control performance will suffer. Hence, depletion of ego strength may lead to increased prejudice. In 2 studies, depletion was found only to affect individuals who normally try to control their prejudicial responses. Participants who do not normally try to control their use of stereotypes were equally prejudiced, regardless of their level of ego strength. The results have implications for prejudice and stereotyping, as well as models of self‐control.     

quantifying the level of congruence between two career measures: an exploratory study

This study investigated the level of congruency between scores on the Self‐Directed Search–Form R (J. L. Holland, 1994) and scores from an online instrument, both of which measure Holland types (J. L. Holland, 1985, 1997). A reasonably high level of congruence was found. Implications for career counselors are briefly delineated.     

The effect of gender stereotype activation on challenge and threat motivational states

The effect of gender stereotype activation on challenge/threat motivational states was examined. Male and female participants completed a difficult math test described as either gender-biased or gender-fair, while continuous cardiovascular data were recorded. During the math test, women in the gender-biased condition exhibited a threatened motivational state, whereas women in the gender-fair condition exhibited challenge. The cardiovascular pattern of data was reversed for men, with men exhibiting challenge when a gender bias was implied, but threat when it was not. Motivational implications of stereotype threat and psychophysiological measurement are discussed.     

Eye movements drive steering: reduced eye movement distribution impairs steering and driving performance

On a winding open road, a driver consistently looks to the inside of each bend before turning the steering wheel. When researchers disrupt this coordination by instructing drivers not to move their eyes, drivers' performance is impaired and their completion time during racing increases. The present authors examined whether changing internal states in a way that also restricts eye movements reduces coordination and affects performance. Participants (N = 24) completed a simulated rally stage under manipulation of their anxiety state through ego threat. Performance decreased under pressure, and the decrement was associated with a narrowing of the range of eye movements and a reduced correlation of eye movements with steering. The authors discuss the possibility that the deterioration in performance is a cost of maintaining steering when eye-movement driving input to the steering controller is reduced.     

A two-dimensional model that employs explicit and implicit attitudes to characterize prejudice

In the authors' 2-dimensional model of prejudice, explicit and implicit attitudes are used to create 4 profiles: truly low prejudiced (TLP: double lows), aversive racists (AR: low explicit modern racism/high implicit prejudice), principled conservatives (PC: high explicit modern racism/low implicit prejudice), and modern racists (MR: double highs). Students completed an Asian Modern Racism Scale and an Asian/White Implicit Association Test. The authors compared the 4 groups' prejudice-related ideologies (i.e., egalitarianism/humanism and social conservatism) and economic/political conservatism (Study 1, N=132). The authors also tested whether MR but not PC (Study 2, N=65) and AR but not TLP (Study 3, N=143) are more likely to negatively evaluate an Asian target when attributional ambiguity is high (vs. low). In support of the model, TLP did not hold prejudice-related ideologies and did not discriminate; AR were low in conservatism and demonstrated the attributional-ambiguity effect; PC did not strongly endorse prejudice-related ideologies and did not discriminate; MR strongly endorsed prejudice-related ideologies, were conservative, and demonstrated the attributional-ambiguity effect. The authors discuss implications for operationalizing and understanding the nature of prejudice.     

Observed Leadership Potential of Personnel in a Team Setting: Big Five traits and proximal factors as predictors

The authors explored implications of Big Five traits and proximal factors for the observed leadership potential of personnel in newly formed teams. Big Five traits were designated as distal factors having indirect links to observed leadership potential via three proximal factors: individual perception of team cohesion, team‐oriented proactivity, and teamwork knowledge. Drawing from implicit personality theory, the authors introduced a team‐leader personality profile as a higher‐order construct for explaining covariation among extraversion, conscientiousness, and emotional stability. A structural analysis of data from 472 personnel supported hypothesized relationships. Specific findings included validation of a team‐leader personality profile and preliminary support for the measure of team‐oriented proactivity that was developed for this study. Implications of the various findings are discussed.     

Measuring model flexibility with parameter space partitioning: an introduction and application example

A primary criterion on which models of cognition are evaluated is their ability to fit empirical data. To understand the reason why a model yields a good or poor fit, it is necessary to determine the data-fitting potential (i.e., flexibility) of the model. In the first part of this article, methods for comparing models and studying their flexibility are reviewed, with a focus on parameter space partitioning (PSP), a general-purpose method for analyzing and comparing all classes of cognitive models. PSP is then demonstrated in the second part of the article in which two connectionist models of speech perception (TRACE and ARTphone) are compared to learn how design differences affect model flexibility.     

Parental detection of youth's self-harm behavior

The rate and predictors of parental detection of youth self-harm behavior and relationship with help-seeking were examined in 7,036 parent-child dyads from the 1999 and 2004 surveys of Mental Health of Children and Young People in Great Britain. Youth self-harm behavior was reported by 463 (6.6%) children and adolescents but only 190 (2.7%) of the parents (kappa=0.30). Reports were more accurate if parents were from majority White ethnicity, were mothers of girls, experienced psychological distress themselves, or if children were older or had emotional/behavioral problems. Parental detection of youth self-harm was associated with increased likelihood of professional help-seeking.
