An in-depth look at scholastic success: Fluid intelligence,personality traits or emotional intelligence?

The aim of the present study was to take an in-depth look at the role of fluid intelligence, personality traits and emotional intelligence (both ability-based and self-reported) in predicting scholastic success, verifying the existence of incremental validity of emotional intelligence with respect to fluid intelligence and personality variables. One hundred twenty-four students attending the last two years of high school were administered: the Advanced Progressive Matrices, the Eysenck Personality Questionnaire Revised Short Form, the Mayer-Salovey-Caruso Emotional Intelligence Test, the Bar-On Emotional Quotient Inventory: Short. The results demonstrate the influence exercised by fluid intelligence, personality and emotional intelligence on scholastic success, underlining, in particular, the role of emotional intelligence defined according to the ability-based model.     

Technical variation in a sample of high level judo players

Technical actions performed by two groups of judokas who won medals at World Championships and Olympic Games during the period 1995-2001 were analyzed. In the Super Elite group (n = 17) were the best athletes in each weight category. The Elite group (n = 16) were medal winners who were not champions and did not win more than three medals. Super Elite judokas used a greater number of throwing techniques which resulted in scores, even when expressed relative to the total number of matches performed, and these techniques were applied in more directions than those of Elite judokas. Further, the number of different throwing techniques and the variability of directions in which techniques were applied were significantly correlated with number of wins and the number of points and ippon scored. Thus, a greater number of throwing techniques and use of directions for attack seem to be important in increasing unpredictability during judo matches.     

Prospective predictors of suicide attempts in borderline personality disorder at one, two, and two-to-five year follow-up

Efforts to identify reliable predictors of suicidal behavior in Borderline Personality Disorder have been confounded by the marked dimensional heterogeneity of the disorder, frequent comorbidity with other high risk disorders, debilitating social and vocational consequences of BPD over time. Using survival analyses, we assessed the predictive association between risk factors in each of these symptom domains and suicide attempts in BPD subjects followed for 12 months, 18-24 months and 2-5 years. The suicide attempt rate was 19% in the first year, 24.8% through the second year. The risk of suicidal behavior among 137 BPD subjects completing the first 12 months was increased by comorbid MDD and poor social adjustment. Outpatient treatment decreased short-term risk. Among 133 subjects completing 18-24 months in the study, the relative risk of a suicide attempt was increased by hospitalization (prior to any attempt), and poor social adjustment. Among 122 subjects followed for 2-5 years, increased risk was associated with hospitalization and medication visits (prior to any attempt), an attempt in the first year, and a low GAS score at baseline. Long term risk was decreased by "any outpatient treatment." Predictors of suicidal behavior in BPD change over time. MDD has a short-term effect on suicide risk, while poor social adjustment may increase risk throughout each follow-up interval. Assessing and supporting family, work, and social relationships may decrease suicidal behavior in BPD, and should be a principal focus of long-term treatment.     

Age-based stereotype threat and negative outcomes in the workplace: Exploring the role of identity integration

Previous studies have shown that the presence of age-based stereotypes in the workplace is often associated with lower levels of work engagement and adjustment among older employees. This study examines possible mediators and moderators of this relationship using data from a sample of 2,348 older (age > 50) employees at the Italian national rail company. We test a model in which the effects of age-based stereotype threat on organizational involvement, future time perspective, and psychological well-being are mediated by work–age identity integration (how much individuals see their age and organizational identities as compatible and blended). Secondly, we explored whether these effects are moderated by gender and job status. Results indicate that age-based stereotypes are associated with negative outcomes for employees’ work and personal adjustment, and that these relationships are partially mediated by variations in work–age identity integration.

Focusing effects in predecisional information acquisition

Legrenzi et al. [Legrenzi, P., Girotto, V., & Johnson-Laird, P. N. (1993). Focusing in reasoning and decision making. Cognition, 49, 37-66] showed that when a single option is proposed for consideration the decision makers limit their information acquisition to this one option, failing to take into account potential alternatives. Unfortunately, the evidence supporting this focusing effect is weak and its determinants are largely unknown. In three experiments, we provided stronger support for the reality of the focusing effect and we identified two significant determinants of this phenomenon. The results show that both representational and value-related manipulations are able to reduce the effect. Results also suggest the need to distinguish between two different types of focusing: representational focusing and search-related focusing.     

Saccade-stepping interactions revise the motor plan for obstacle avoidance

The authors used a stimulus-response compatibility paradigm to assess the effect of changing the estimated time to obstacle contact. A limb-selection cue was presented in different phases of gait to young (n = 5) and to older (n = 4) adults while they were moving toward a foam obstacle in the walking path. A downward saccade was initiated after the cue; the saccade typically occurred during the stance phase of the target limb (the foot cued to lead the step over the obstacle). The mean saccade-step latency after the cue was on the order of -500 ms in both young and elderly participants. On reaching the obstacle, both groups generated an upward saccade approximately -300 ms before target footlift in both groups. Saccades following the limb-selection cue appeared to direct the gaze toward footfall targets just beyond the obstacle, whereas saccades generated just before obstacle footlift moved the gaze to the forward-looking direction. The elderly had significantly longer saccade-trailing-footlift latencies and prolonged gaze-fixation times than did the younger adults. Transient disruptions in optical flow appeared to be necessary for successful obstacle-avoidance behavior when there was an unexpected change in the estimated time to obstacle contact.     

CS-dependent response probability in an auditory masked-detection task: considerations based on models of Pavlovian conditioning.

Experimental studies were performed using a Pavlovian-conditioned eyeblink response to measure detection of a variable-sound-level tone (T) in a fixed-sound-level masking noise (N) in rabbits. Results showed an increase in the asymptotic probability of conditioned responses (CRs) to the reinforced TN trials and a decrease in the asymptotic rate of eyeblink responses to the non-reinforced N presentations as a function of the sound level of the T. These observations are consistent with expected behaviour in an auditory masked detection task, but they are not consistent with predictions from a traditional application of the Rescorla-Wagner or Pearce models of associative learning. To implement these models, one typically considers only the actual stimuli and reinforcement on each trial. We found that by considering perceptual interactions and concepts from signal detection theory, these models could predict the CS dependence on the sound level of the T. In these alternative implementations, the animals response probabilities were used as a guide in making assumptions about the "effective stimuli".
