Verb frame preferences: Descriptive norms

This paper presents normative data about the frequency with which college students construct sentences with different syntactically defined frames for 127 English verbs. The norms are intended to be of use to experimenters in preparing materials to study sentence comprehension.     

Differential effects of emotional arousal in short- and long-term memory in healthy adults

Recent studies demonstrated important differences between short- and long-term memory mechanisms. Besides, the emotional component has a crucial role in memory formation. This study was carried out to answer whether there is a differential influence of emotional arousal in short- and long-term memory in healthy adults. Thirty-one healthy volunteers were divided into two major groups. In the first group long-term memory (LTM) was evaluated, with the testing session one week after training. The second group was tested 1h after training, where short-term memory (STM) was evaluated. Each group was divided in to two subgroups. One half of the volunteers was exposed to an emotionally neutral story, and the other half of each group was exposed to a closely matched but more emotionally arousing story. The testing session consisted of a questionary containing 80 questions of multiple choices. The results were evaluated through percentage of correct answers. Results showed that correct answers were increased, in LTM measures, in the subjects that were given the emotional version of the test. In STM measures, no differences were found between the emotional and neutral version. However, the presentation of emotional story caused an emotional reaction in both groups. The lack of effect of emotional arousal in STM suggests that amygdala is not related to STM mechanisms. Further studies using different approaches are needed to elucidate if STM processes are influenced by emotional arousal.

Purpose  

This study investigated whether meeting electronically first using computer-mediated communication (CMC) before meeting face-to-face (FTF) increases the inclusion of a female group member in a predominantly male project team.     

The role of inhibition in the production of disfluencies

Disfluency is a common occurrence in speech and is generally thought to be related to difficulty in the production system. One unexplored issue is the extent to which inhibition is required to prevent incorrect speech plans from being articulated. Therefore, we examined disfluency production in participants with attention-deficit/ hyperactivity disorder (ADHD), which is linked to deficits in inhibitory function and response suppression (Nigg, 2001). Participants completed a sentence production task in which they were presented with two pictures and a verb and their task was to produce a sentence. If inhibition plays a role in preventing incorrect speech plans, we would expect ADHD participants to produce more repetition and repair disfluencies than would non-ADHD controls. The results showed that one subtype of ADHD (i.e., the combined) produced more repair disfluencies as task demands increased. We conclude that the production system relies on inhibitory control in order to prevent errors in language production.     

Trajectories of Experience of Real Life Events. A Semiotic Approach to the Dynamics of Positioning

This paper is devoted to the study of experience as a semiotic process of constructing the personal meaning of the situation lived. Its main purpose is to devise a semiotic methodology capable of describing and explaining the dynamics of positioning when facing personal lived experiences in real life contexts. Twenty four young adults were exposed to a simulated conflict and then asked to write a narrative of their understanding of the incident and a self-report of their personal experiences. Results show how narratives and trajectories of experience present different forms in each participant, which could be related to: a) the understanding of the situation lived and the position taken regarding the conflict; and b) the position each participant takes regarding the reports they had to produce for the researchers. The incorporation of reflexivity into the applied method allows identification of how the dynamics of double positioning leave traces in the records produced.     

Informativity renders a referent more accessible: Evidence from eyetracking

The amount of information attached to a noun phrase (henceforth, NP) has been shown to enhance accessibility and increase pronominal reference in language production. However, both the effect of information quantity on the comprehension of ambiguous pronouns and the time course of any informativity effect have been left unexplored. In two eyetracking experiments, we investigated how additional information on the part of NP referents influenced the resolution of following ambiguous pronouns. The results of the first experiment revealed an informativity effect, with more looks to the informationally richer referent than to the competitor. However, the effect of additional information emerged late in time when the referent was the object of the verb. The second experiment replicated the results of the first and also showed that, consistent with the online results, an ambiguous pronoun is interpreted as referring to the informationally richer NP in an offline, explicit pronoun resolution task. The results lend support to theories of language processing that assume that explicit information increases the accessibility of the associated concept, in contrast to approaches that assume that accessibility is associated with givenness.     

A Multidisciplinary Approach to Sexual Behavior Profiles: The SEX360 Model

The diversity of sexual behaviors is driven by multiple determinants, including physiological, cultural, educational, and sociological factors. However, the definition of sexual behavior profiles has been barely addressed from a comprehensive point of view. We aimed to develop a multidisciplinary questionnaire for defining individual sexual behavior profiles. The questionnaire was developed by a panel of experts with research experience in the fields of urology, gynecology, psychology, anthropology, and sexology. The list of items was defined in a focus group session and was based on four categories—family-oriented, loving, recreational, and functional—resulting from the combination of two axes: traditional versus non-traditional and sexual benefit versus extra-sexual benefit. Real-time Delphi dynamics was used to assign a weight to each question and a bias to the corresponding responses. The final questionnaire included 50 items considered relevant for describing sexual profiles; the final questionnaire was named SEX360. Of the 50 items included in SEX360, 14 were considered essential for computing the final score; 9 of them were associated with 2 categories, 4 of them with 4 categories, and 1 of them with 3. Nine items referred to the category “family-oriented”, 10 to “loving”, 8 to “recreational”, and 9 to “functional”. The weights assigned to each question ranged from 3.00 to 4.33, and the centers of gravity ranged from 1 to 4. The questionnaire proposed shows the existence of a vast diversity of sexual behavior profiles and may serve as a tool for sexual behavior research.     

Coding processes and executive functions in multiple sclerosis

Although episodic memory deficit in patients with multiple sclerosis (ME) is a well established fact, there is no agreement about the origin of this disorder in terms of cognitive processes. Whereas most of the studies attribute this deficit to defects in memory recovery processes, others contribute evidence in favor of the hypothesis that considers that it originates in difficulties in coding memory processes.However, the analysis of the relationship between coding processes and memory functioning in ME is a scantly studied topic. In the present article, we studied coding processes and their relationships with executive control processes in a group of patients with ME. We used a set of indexes of the Test of Verbal Learning from the TAVEC test for the evaluation of the coding processes. To assess the executive processes we used a semantic verbal fluency task, the WCST, and WAIS III scale of matrixes. We worked with 36 patients with ME diagnosis and 36 healthy control participants, paired by age and educational level. The results showed a deficit in the coding processes and the existence of a significant association between these processes and executive functioning.

Electrical stimulation of the pedunculopontine tegmental nucleus in freely moving awake rats: time- and site-specific effects on two-way active avoidance conditioning

The pedunculopontine tegmental nucleus (PPTg) is involved in the regulation of thalamocortical transmission and of several functions related to ventral and dorsal striatal circuits. Stimulation of the PPTg in anesthetized animals increases cortical arousal, cortical acetylcholine release, bursting activity of mesopontine dopaminergic cells, and striatal dopamine release. It was hypothetized that PPTg stimulation could improve learning by enhancing cortical arousal and optimizing the activity of striatal circuits. We tested whether electrical stimulation (ES) of the PPTg, applied to freely-moving awake rats previously implanted with a chronic electrode, would improve the acquisition and/or the retention of two-way active avoidance conditioning, and whether this effect would depend on the specific PPTg region stimulated (anterior vs posterior) and on the time of ES: just before (pre-training) or after (post-training) each of three training sessions. The treatment consisted of 20 min of ES (0.2 ms pulses at 100 Hz; current intensity: 40-80 microA). The results showed that (1) this stimulation did not induce either any signs of distress nor abnormal behaviors, apart from some motor stereotyped behaviors that disappeared when current intensity was lowered; (2) pre-training ES applied to the anterior PPTg improved the acquisition of two-way active avoidance, (3) no learning improvement was found after either post-training ES of the anterior PPTg, or pre- and post-training ES of the posterior PPTg. The results give support to a role of PPTg in learning-related processes, and point to the existence of functional PPTg regions.
