Emotion and recognition memory: the discrimination of negative information as an adaptive process

We studied the effect of emotion generated by IAPS (International Affective Picture System) pictures on incidental recognition of these pictures for short retention periods (15 min). Memorization distraction tasks and reaction time tasks were used together with short exposure times (2 seconds per picture) in order to prevent a high recognition rate that would impede testing for the effect of emotion on discrimination parameters (A′) and response bias (B′′D) (ceiling effect). We used 80 pictures representing the medium and high levels of two-dimensional emotional space. The results showed greater discrimination and a more conservative response style to unpleasant and medium arousal level pictures. These pictures produced higher confidence and lower response times in the recognition phase. The results can be explained by the negative content of the pictures and activation level effects on attentional processing and memory, and can be interpreted as a phenomenon that is evolutionarily adaptive.     

Staffing Services Quality and Innovativeness in Pharmaceutical Companies

This paper examines whether the main dimensions of staffing services quality have any effect on innovativeness. A resource‐based view of human resource management is used as theoretical approach. A questionnaire was sent to the CEOs of an international sample of pharmaceutical companies. A regression analysis was used to test hypotheses about the influence of the staffing services quality dimensions on innovativeness. The main findings are that all but one of the staffing services quality dimensions considered have significant, positive effects on innovativeness. Candidate quality is the dimension that affects innovativeness most, while timeliness has no significant effect.     

Polyaminergic agents modulate contextual fear extinction in rats

Polyamines, such as spermidine and spermine, have been reported to improve memory retention through the activation of N-methyl-d-aspartate receptors (NMDAr). However whether polyamine agonists and antagonists alter extinction remains unclear. In the current study, we investigated whether spermidine and polyamine antagonists that selectively block the NR2B subunit at the NMDAr alter the extinction of contextual conditioned fear in male Wistar rats. The bilateral intra-hippocampal administration of exogenous spermidine (2 nmol/site) immediately after, but not 6 h after extinction training, facilitated the extinction of fear conditioning. The injection of the NMDAr antagonists arcaine (0.2 nmol/site), ifenprodil (20 nmol/site) and traxoprodil (0.2 nmol/site), disrupted fear extinction and, at doses that had no effect per se, reversed the facilitatory effect of spermidine on fear extinction. These results suggest that exogenous and endogenous polyamines facilitate the extinction of contextual conditioned fear through activation of NR2B subunit-containing NMDAr in the hippocampus. Since extinction-based exposure therapy is widely used as treatment for a number of anxiety-related disorders, including phobias and post-traumatic stress, the currently reported facilitation of extinction by polyaminergic agents suggest these compounds as putative candidates for drug development.     

Work Context Support and Portuguese Soldiers’ Well-Being: The Mediating Role of Autonomous Motivation

Using self-determination theory ( Deci & Ryan, 2008 Deci, E. L., & Ryan, R. M. (2008). Self-determination theory: A macrotheory of human motivation, development, and health. Canadian Psychology, 49, 182–185. 10.1037/a0012801[Crossref], [Web of Science ®] , [Google Scholar]) as the theoretical framework, we tested a model for this study that considers soldiers’ perceptions of organizational support and leader–member exchange (LMX), work motivation, and well-being at work. The hypothesized model was tested using a representative sample of 1,045 Portuguese soldiers. Results revealed that autonomous work motivation was significantly related to both contextual factors (organizational support and LMX). In addition, autonomous work motivation was positively related to work engagement and negatively related to burnout, and controlled motivation showed the opposite pattern. More interesting, the results showed that autonomous work motivation as a mechanism that helped to explain the relationship between both contextual factors and workplace well-being. The present results underscore the importance of understanding the mechanisms through which higher work engagement and lower burnout take place, eventually leading to appropriate interventions.     

The contribution of prefixes to morphological processing of Spanish words

Three series of priming experiments were conducted to probe the morphological and phonological contributions to visual word recognition in Spanish. Prefixed, e.g., INCAPAZ (incapable), and pseudoprefixed, e.g., INDUSTRIA (industry) target words were presented for recognition following a prefixed, e.g., infeliz (unhappy), or pseudoprefixed, e.g., insulto (insult), prime starting with the same syllable as the target, at masked short or long stimulus onset asynchronies (SOAs). At long SOAs the recognition of prefixed targets was facilitated by prefixed primes and inhibited by pseudoprefixed ones, whereas both prefixed and pseudoprefixed primes facilitated the recognition at short SOAs. In contrast, the recognition of pseudoprefixed targets was unaffected by the kind of prime presented, even when we used pairs of words overlapping in syllables that cannot be prefixes in Spanish. These results support a special status for morphological elements in access to meaning in reading.     

Word naming in Spanish

Studies on the factors that determine word naming speed have been conducted in a number of languages. In this study two objectives were pursued: (1) to contrast the effects of the variable of age of acquisition with the different measures of frequency of use (adult written frequency, child written frequency, cumulative frequency, and frequency trajectory), and (2) to verify which variables determine reading latencies in a language with a completely transparent reading system (Spanish). For these purposes, 53 native speakers of Spanish read aloud 240 words for which values were available of the main lexical, phonological, and semantic variables. The results of the regression analyses showed that the best predictors of reading times were length (measured in terms of both number of letters and number of syllables) and subjective age of acquisition (AoA). The different frequency measures correlated significantly with the response latencies but were not longer significant in the regression analyses. Semantic variables (familiarity and imageability) had the smallest effects on reading speed. The comparison of the results obtained in this study with those reported for other languages offers some conclusions about the effects of orthographic systems on word naming.     

Effects of Decision Training on Decision Making and Performance in Young Tennis Players: An Applied Research

This study examined the effectiveness of a 10-week decision training program on decision making and performance in tennis. Decision training was based on the analysis combining tactical questioning and video feedback about players own actions. A quasi-experimental design with intermediate tennis players (control group, n = 6; experimental group, n = 5) was developed over 18 weeks, divided into 3 phases: preintervention, postintervention, and retention. A total of 13,383 game play actions were analyzed to test differences. Experimental group improves significantly decision making and performance and maintained improvements during the retention phase. Video feedback combined with questioning is recommended to achieve sport expertise.
