“Economic Crisis and Poaching: Advice on Anti-Poaching Management from The Galician Shellfish Sector”

ABSTRACT

The aim of this work is to prove the significant relationship between the economic crisis and the increase of the shellfish poaching in Galicia (NW Spain) during the period 2008–2012. A relationship was observed between the “necessity” causes and the economic incentives as an explanation for shellfish poaching. The results achieved pointing out the importance to complete the coercive dissuasive methods in the fight against poaching using informal management mechanisms implemented in Galician shellfish communities, especially in co-managed contexts in which unemployment and necessity processes are identified.     

The Depressive Attributions Questionnaire (DAQ): Development of a Short Self-Report Measure of Depressogenic Attributions

A depressogenic attributional style, i.e., internal, stable and global causal interpretations of negative events, is a stable vulnerability factor for depression. Current measures of pessimistic attributional style can be time-consuming to complete, and some are designed for specific use with student populations. We developed and validated a new short questionnaire suitable for the measurement of depressogenic attributions in clinical settings, the Depressive Attributions Questionnaire (DAQ). The 16-item DAQ, and measures of depression and related cognitive concepts were completed by three samples of depressed patients and matched controls, or depressed and non-depressed participants who had been exposed to a recent uncontrollable stressful life event (total N = 375). The DAQ had high (i) internal reliability, (ii) test-retest reliability, (iii) convergent, discriminant and construct validity. It predicted a diagnosis of major depression at 6 months after an uncontrollable stressor, over and above what could be predicted from initial depression severity. Depressed patients rated the scale as acceptable. The DAQ may be a useful short measure of depressogenic attributions, which is easy to administer, and predicts concurrent and future depression. It has possible applications as a screening measure for risk of depression, or as a treatment process measure.     

Inhibitory processes, working memory, phonological awareness, naming speed, and early arithmetic achievement

This study identified the cognitive processes that underlie the individual differences in early mathematical performance in elementary school children. Taking into account the Baddeley framework multicomponent model, the inhibitory processes, working memory, phonological awareness, and naming speed are considered to be related to early math learning. To examine this relationship, we compared the performance of a total of 424 typically developing middle-class children, aged between 4 and 7 years in a battery of cognitive and early numeric tests: The Utrecht Early Numeracy Test, the Rapid Automatized Naming Test, Spanish version of the Stroop task, the Numeracy Interference Test, Digit Span test, and Phonological Knowledge Test. The mean age of the participants was 72.21 months (sd = 14.8), and 48.6% were male and 51.4% were female. The results demonstrated that children performing worst on central executive, phonological processing, and inhibitory processes showed lower results in early mathematical tasks measured by The Utrecht Early Numeracy Test. Results supported the notion that the executive system is an important predictor of children's mathematical performance.     

What else do you feel when you feel sad? Emotional overproduction, neuroticism and rumination

Numerous experimental and naturalistic studies have shown the relevant role of ruminative styles in the onset, duration and severity of depressive episodes. Recent research has increasingly focused on the precursors of these ruminative responses. Neuroticism has been found to be closely related to ruminative styles, but the nature of this relationship is unknown. Across three studies, we explored the role of emotional overproduction, conceptualized as the tendency to simultaneously experience an elevated number of negative emotions and feelings during sad episodes. Study 1 showed that emotional overproduction is independently and strongly associated with ruminative styles. Furthermore, emotional overproduction was found to mediate the relationship between neuroticism and ruminative styles. Study 2 replicated these findings in a large community sample even after controlling for mood, personality, and other emotion-related variables. In Study 3, we conducted a laboratory study to increase the internal and external validity of our findings. Implications for personality, for coping and stress literature, and for clinical research and treatment are suggested.     

Stimulus Control with Computer Assisted Learning

Computer Assisted Learning (CAL) has been shown to be an efficient learning-teaching procedure. Although there is an extensive educational software tradition using CAL approaches, few of them have demonstrated a better student performance than standard drill and practice methods. The purpose of this study was (a) to evaluate the effectiveness of the Let's Play With... software program, and (b) to evaluate the effectiveness of a prompt (i.e. a blinking object) used in the program. The educational software Let's Play With... was designed to teach basic concepts involving shapes and body positions to preschool students. The software structure follows a behavioral design and uses a stimulus control procedure. The study was carried out with 64 preschool students in the Cadiz (Spain) School District. Statistically significant differences were found between the experimental group and a control group.     

A comparator view of Pavlovian and differential inhibition

In 3 experiments using rats as subjects, the authors varied trial spacing to investigate the conditions under which Pavlovian and differential inhibition are observed. Experiment 1 compared Pavlovian and differential inhibition with spaced training trials. Spaced trials resulted in only the Pavlovian inhibitor passing both summation and retardation tests. Conversely, Experiment 2 compared these 2 types of inhibition with massed training trials. This training resulted in only the differential inhibitor passing both tests for conditioned inhibition. Finally, in Experiment 3 all subjects experienced Pavlovian inhibition training with massed trials. Although this training by itself did not result in behavior indicative of inhibition, subjects that also experienced posttraining extinction of the training context did pass both tests for inhibition. Overall, these results are anticipated by the extended comparator hypothesis (Denniston, Savastano, & Miller, 2001) but are problematic for most contemporary associative learning theories.     

Latent inhibition in human affective learning

This study presents the results of a new visual procedure designed to generate affective learning, namely the change in the affective rating of a previously neutral stimulus by simply pairing it with a liked or disliked stimulus. Specifically, an experiment was conducted to evaluate the effect of nonreinforced preexposures to the to-be-conditioned stimulus (a non-sense shape) on affective conditioning. This manipulation, intended to produce latent inhibition, typically results in retarded learning when the preexposed stimulus is paired with the unconditioned stimulus. The results revealed that it is possible to modify the affective value of a previously neutral non-sense shape by pairing it with a liked or disliked unconditioned stimulus, and that latent inhibition affects affective conditioning.
