Ethnic Pride and Cardiovascular Health Among Mexican American Adults Along the U.S.-Mexico Border

This study addressed the association between items from the General Acculturation Index (GAI) and cardiovascular health. Specifically, we assessed whether ethnic pride was associated with health outcomes after controlling for items regarding language, place where the childhood was spent and ethnic interaction. The study was a cross sectional analysis of demographic and clinical data from a border population of Mexican American adults (n=316) at risk for cardiovascular disease (CVD). Outcomes included smoking and diabetes status, Framingham risk, and metabolic syndrome. Ethnic pride was associated with lower diabetes prevalence, lower Framingham risk, and fewer risk factors for metabolic syndrome, but was not associated with smoking status. Ethnic pride was not associated with the other acculturation items of the GAI. Among an at-risk border population, ethnic pride functioned independently of other acculturation indicators. Ethnic pride may act as a protective factor for diabetes, metabolic syndrome and CVD risk status.     

The influence of object identity on obstacle avoidance reaching behaviour

When reaching for target objects, we hardly ever collide with other objects located in our working environment. Behavioural studies have demonstrated that the introduction of non-target objects into the workspace alters both spatial and temporal parameters of reaching trajectories. Previous studies have shown the influence of spatial object features (e.g. size and position) on obstacle avoidance movements. However, obstacle identity may also play a role in the preparation of avoidance responses as this allows prediction of possible negative consequences of collision based on recognition of the obstacle. In this study we test this hypothesis by asking participants to reach towards a target as quickly as possible, in the presence of an empty or full glass of water placed about half way between the target and the starting position, at 8 cm either left or right of the virtual midline. While the spatial features of full and empty glasses of water are the same, the consequences of collision are clearly different. Indeed, when there was a high chance of collision, reaching trajectories veered away more from filled than from empty glasses. This shows that the identity of potential obstacles, which allows for estimating the predicted consequences of collision, is taken into account during obstacle avoidance.     

Psychologische Interventionen bei Personen mit erhöhtem Psychoserisiko

Indicated prevention in individuals at clinical high risk for first episode psychosis is hoped to delay the onset of the disorder or even prevent the transition to full-blown psychosis. Remission of at-risk symptoms, psychosocial functioning and quality of life are secondary outcomes. According to current evidence cognitive behavioral therapy can be considered the best evaluated stand alone therapy approach for the prevention of psychosis. The treatment of persons at risk for first episode psychosis is associated with the risk of exposing falsely identified persons to potential side effects; therefore, treatment with the best risk-benefit ratio should be chosen. Consequently, monitoring within specialized early recognition centers should be considered first, followed by a customized psychoeducation. The data on psychoeducation of people at risk for psychosis are encouraging but still not sufficient. Methodological issues and differences of the evaluated approaches are discussed.     

Effects of soundtrack music on the video game experience

ABSTRACT

Aesthetic elements such as soundtrack music have been neglected in game entertainment research. Based on previous work in games research and the psychology of film soundtracks (Cohen, 2001), we test the hypotheses that soundtrack music contributes to players‘ enjoyment via intensification of emotions (affective route) and via amplification of the sense of spatial presence and identification with the game character (cognitive routes). Study 1 tested these assumptions with N = 68 young male players of an episode of Assassin’s Creed: Black Flag^®, either with the original soundtrack music present or absent, and reported game enjoyment, as well as scores of the assumed mediator variables afterward. In Study 2, N = 59 young males played an episode of Alien: Isolation^® with soundtrack music present or absent and reported their horror experience, as well as the experiential facets as in study 1. Findings clearly show an indirect effect of soundtrack music on enjoyment through positive emotions (study 1) and an impact of (shocking) music on players’ horror experience (study 2). However, a mediation of the effect of soundtrack music on game enjoyment via spatial presence or identification was not established. We discuss implications for future research in game entertainment.     

Visualising fragrances through colours: the mediating role of emotions

To facilitate communication about fragrances, one can use the colours people tend to associate with their smells. We investigated to what extent odour-colour correspondences for fine fragrances can be accounted for by underlying emotional associations. Odour-colour matches and degree-of-fit judgments revealed that odours were matched to colours non-randomly. Matching colours differed mainly on blackness (brightness), and less on chromaticness (saturation) and hue. Furthermore, we found a consistent negative relationship between odour-colour degree-of-fit ratings and the difference between the odour scores and the colour scores on one of the emotion dimensions (pleasure). This suggests that emotional associations may partly underlie odour-colour correspondences.     

The perceived importance of sensory modalities in product usage: a study of self-reports

Although popular belief holds that vision dominates human experience, this does not necessarily imply that people regard vision as the most important sensory modality during the interaction with every product. Instead, the relative importance of the different modalities is likely to depend on the type of product and on the task performed. In Study 1, respondents reported how important they found vision, audition, touch, taste, and smell during the use of 45 different products. In Study 2, the respondents answered a similar question for the evaluation of the safety, ease of use, and enjoyment experienced for 15 products. Importance ratings for the sensory modalities differed considerably between the products. Differences due to the types of evaluations were smaller. Averaged over products and evaluation types, vision was the most important sensory modality for product evaluations, followed by touch, smell, audition, and taste. However, for about half of the individual products, the importance ratings for vision were lower than for one of the other modalities. These findings are in line with the view that vision is regarded the dominant modality, because it plays an important part in many and an irrelevant part in virtually no product experiences.     

Cognitive procedural learning in patients with fronto-striatal lesions

Previous studies on the role of prefronto-striatal loop systems for cognitive procedural learning (PL) brought inconsistent results. To examine whether the integrity of the dorsolateral prefrontal loop is indispensable for normal cognitive PL, we examined the acquisition of cognitive skills in 35 patients with focal prefrontal lesions, focal caudate lesions, and Huntington's Disease (HD), and compared it with a control group. To examine the potential role of the processing demands made by the cognitive tasks, a set of tasks was applied whose acquisition places demand either on reasoning and problem solving, or on the establishment of fast and repetitive processing routines. The Pursuit Rotor task was also studied with the aim to re-examine earlier findings of a functional segregation of motor and complex prefronto-striatal loops. Deficits of cognitive and motor PL were found to be limited to certain tasks and groups. PL of one task, which demanded rapid, repetitive processing of visuo-spatial stimuli, was impaired in all patient groups. PL of two problem-solving tasks was impaired in patients with focal and degenerative caudate lesions only. None of the groups was impaired at PL of Mirror Reading, another task demanding rapid and repetitive visuo-spatial processing, and none was impaired in a fifth task of language skill. Deficits of motor learning were only observed in patients in whom the motor loop was affected. These results suggest that the dorsolateral prefronto-striatal loop is involved in the establishment of cognitive processing routines. The comparison of patients with and without caudate lesions suggests that disconnection of this circuit is critical. However, the normal acquisition of two cognitive tasks even in this group indicates that the integrity of the dorsolateral prefrontal loop is not mandatory for normal cognitive PL. We discuss these dissociations with regard to the demand profiles of the applied tasks and the locations of the lesions.     

Sequence effects in hedonic judgments of taste stimuli

Sequential dependencies in taste research may be different from those obtained in other modalities, due to the long interstimulus intervals and the intermediate rinses. In two experiments, subjects judged the pleasantness of 50 aqueous solutions on 150-mm line scales. During data analyses pseudo-sequence effects arose, because data were aggregated over individuals and because the first trials of the experimental sessions deviated from the rest. After correcting for the pseudo-sequence effects, robust regression analyses revealed small but significant sequential dependencies. The current response deviation was positively related to previous response deviations and negatively related to previous subjective, internal representations.     

The interplay between feedback-related negativity and individual differences in altruistic punishment: An EEG study

To date, the interplay betwexen neurophysiological and individual difference factors in altruistic punishment has been little understood. To examine this issue, 45 individuals participated in a Dictator Game with punishment option while the feedback-related negativity (FRN) was derived from the electroencephalogram (EEG). Unlike previous EEG studies on the Dictator Game, we introduced a third party condition to study the effect of fairness norm violations in addition to employing a first person perspective. For the first time, we also examined the role of individual differences, specifically fairness concerns, positive/negative affectivity, and altruism/empathy as well as recipients’ financial situation during altruistic punishment. The main results show that FRN amplitudes were more pronounced for unfair than for fair assignments in both the first person and third party perspectives. These findings suggest that FRN amplitudes are sensitive to fairness norm violations and play a crucial role in the recipients’ evaluation of dictator assignments. With respect to individual difference factors, recipients’ current financial situation affected the FRN fairness effect in the first person perspective, indicating that when being directly affected by the assignments, more affluent participants experienced stronger violations of expectations in altruistic punishment decisions. Regarding individual differences in trait empathy, in the third party condition FRN amplitudes were more pronounced for those who scored lower in empathy. This may suggest empathy as another motive in third party punishment. Independent of the perspective taken, higher positive affect was associated with more punishment behavior, suggesting that positive emotions may play an important role in restoring violated fairness norms.     

Intellectual ability, learning style, personality, achievement motivation and academic success of psychology students in higher education

This study is directed towards an integration of intellectual ability, learning style, personality and achievement motivation as predictors of academic success in higher education. Correlational analyses partly confirmed and partly disconfirmed our expectations in a sample of 409 first-year psychology students. Consistent with the literature, intellectual ability and achievement motivation were associated positively with academic success. For the meaning directed, reproduction directed and application directed learning style, no positive association with academic success could be detected. The undirected learning style, however, appeared to be a consistent negative predictor. For the Big Five personality factors (extraversion, agreeableness, conscientiousness, neuroticism and openness to experience), a consistent, positive association for conscientiousness with academic success was found. The very first examination at the university came out as the most important predictor for academic success, even after two and three years of study. The implications of the results are discussed in relation to the literature and the policy of the Dutch Ministry of Education.
