Facelikeness matters: A parametric multipart object set to understand the role of spatial configuration in visual recognition

There is a view that faces and objects are processed by different brain mechanisms. Different factors may modulate the extent to which face mechanisms are used for objects. To distinguish these factors, we present a new parametric multipart three-dimensional object set that provides researchers with a rich degree of control of important features for visual recognition such as individual parts and the spatial configuration of those parts. All other properties being equal, we demonstrate that perceived facelikeness in terms of spatial configuration facilitated performance at matching individual exemplars of the new object set across viewpoint changes (Experiment 1). Importantly, facelikeness did not affect perceptual discriminability (Experiment 2) or similarity (Experiment 3). Our findings suggest that perceptual resemblance to faces based on spatial configuration of parts is important for visual recognition even after equating physical and perceptual similarity. Furthermore, the large parametrically controlled object set and the standardized procedures to generate additional exemplars will provide the research community with invaluable tools to further understand visual recognition and visual learning.     

The role of partners and children for employees' daily recovery

This multi-source diary study examined the role of partners for employees' daily recovery in a sample of dual-earner couples. We hypothesized that employees' daily psychological detachment from work during the evening should be positively associated with their partners' daily psychological detachment during the evening. Employees' affective well-being (serenity and negative activation) at bedtime should be influenced not only by their own psychological detachment, but also by their partners' psychological detachment. Moreover, we hypothesized that the presence of children in a couple's household should moderate the relations between partners' psychological detachment on the one hand, and employees' psychological detachment and affective well-being on the other hand. Fifty-three dual-earner couples completed daily electronic surveys via handheld devices at bedtime over the course of one work week. We used dyadic multilevel path modeling to analyze our data. Results showed that employees' and their partners' levels of daily psychological detachment were positively related. Employees' psychological detachment predicted their own negative activation, but not their serenity at bedtime. Partners' psychological detachment predicted employees' serenity and negative activation only in couples without children. Hence, our study provides support for the relevance of partners and children for employees' daily recovery after work.     

Influence of judges' behaviors on perceived procedural justice

The influence of judges' behaviors on procedural justice was analyzed in a field study, observing the judges' behaviors during n = 129 trials and assessing the defendants and the audiences' justice perceptions. The observed judicial behavior was unrelated to the defendants' justice perceptions. However, the more respectful the judge treated the defendants, the fairer the audience perceived the trial. In general, the effect size of the relationship between observational measures and subjective justice ratings was small in comparison to the relationship within defendants' or audiences' ratings. There were striking differences in the justice perception between the two data sources, namely defendants and audience. Thus, the source matters, and to avoid a same‐source bias, should be taken into account when analyzing justice perceptions.     

Mit Imagination an Albträumen arbeiten

According to Jung fantasies appear during sleep as dreams and while awake, they appear as more or less conscious fantasies. He understood fantasy as an activity of the psyche itself. Fantasy is that which simply occurs without any effort on our part and is always present. Imagination is what we call fantasy when we concentrate on it, i.e. perceive it and do something with it. Due to the close relationship of dreams, fantasies and imagination, the more they are consciously observed and perceived, the more it is possible to use imagination with dreams to better understand them. This is especially true for nightmares so that through imagination helplessness can be overcome and self-efficacy can be stimulated. Steven Starker already proposed using imagination for working on nightmares in 1974 and he also showed how the style of the nocturnal dreams changed as a consequence. In a clinical vignette I show how this technique can be used and what an influence it has. The analyst and analysand are in a communal space of visualization, framed in the beginning by the nightmare. This space is considered as a space of interaction and of potential transformation. The analyst is a part of the process, offering ideas in a symbolic form and reinforcing the analysand’s ideas which lead to stress-reducing behaviour and images that provide an opening for the future. There are pauses in the imaginative work to talk together about the experiences, to link the situation in the imagination to biographical material, and to understand the resources opening up in the material, through the analysand herself. The goal of working with imagination is to ban the anxiety in the dream and to let the dreamer experience the fact that dreams and imagination are not only determined by the anxious feelings but it is also possible to transform these kinds of energy into creative fantasies.     

Multimedia Learning in a Second Language: A Cognitive Load Perspective

What can be done to help college students who are not native speakers of English learn from computer‐based lessons that are presented in English? To help students access the meaning of spoken words in a slow‐paced 16‐minute narration about wildlife in Antarctica, a representational video was added that showed the scenes and animals being described in the narration (Experiment 1). Adding video resulted in improved performance of non‐native English speakers on a comprehension test (d = 0.63), perhaps because the video improved access to word meaning without creating extraneous cognitive load. To help students perceive the spoken words in a fast‐paced 9‐minute narrated video about chemical reactions, concurrent on‐screen captions were added (Experiment 2). Adding on‐screen captions did not improve performance by non‐native English speakers on comprehension tests, perhaps because learners did not have available capacity to take advantage of the captions. Implications for cognitive load theory are discussed. Copyright © 2014 John Wiley & Sons, Ltd.     

Does temporal preparation facilitate visual processing in a selective manner? Evidence from attentional capture

The present study addressed the question of whether temporal preparation influences perceptual stimulus processing in a selective manner. In three visual search experiments, we examined whether temporal preparation aids spatial selection and thus reduces distraction caused by the onset of a task-irrelevant item. In each trial, participants had to detect a target amongst five non-targets and report a basic feature of the target. In some trials, an additional task-irrelevant singleton item (abrupt onset) appeared on the screen which distracted attention away from the target. To manipulate the degree of distraction, we varied the spatial distance and the stimulus-onset asynchrony between target and singleton. Temporal preparation for the target varied by means of constant foreperiods of different lengths. Though we observed overall faster responding in the case of high temporal preparation in all three experiments, temporal preparation did not reduce spatial distraction by the abrupt onset, even when the spatial position of the target was predictable. In sum, this pattern of results does not provide support for an influence of temporal preparation on spatial selection. Instead, it indicates that temporal preparation affects early visual processing in a non-selective manner.     

Measuring Processing Fluency: One versus Five Items

While there is an ample amount of consumer behavior research that recruits processing fluency as an explanatory construct, the question how to best measure the fluency experience has received little attention. Therefore, there is a lack of consistency in measuring the construct, particularly with regard to the use of single‐item versus multi‐item measures. The current research, thus, aims to investigate how processing fluency can be consistently measured across different experimental fluency manipulations and which type of measure has the highest validity. Based on classic scale development procedures, we propose a reliable and valid multi‐item measure and compare this measure against a single‐item measure in terms of predictive validity. We show that both measures mediate the effect of five established fluency manipulations and that the single‐item measure is sufficient. In addition to providing a measure for future research that can be adapted to different empirical settings, we provide empirical evidence on the replicability of fluency effects and on the theoretical conjecture that people have a uniform fluency experience across different manipulations of fluency.     

Hippocampal activation of immediate early genes Zenk and c-Fos in zebra finches (Taeniopygia guttata) during learning and recall of a spatial memory task

Zebra finches (Taeniopygia guttata) are able to learn the position of food by orienting on spatial cues in a ‘dry water maze’. In the course of spatial learning, the hippocampus shows high expression of the immediate early genes (IEGs) Zenk and c-Fos, indicating high activation of this area during learning. In contrast, the IEG activity is nearly absent if the birds do not have to rely on spatial cues. In the present experiment it was investigated whether hippocampal activation can also be observed if the learned spatial task is recalled. For this purpose, the hippocampal Zenk and c-Fos activation of birds in an early learning stage was compared with that of others having well reached their maximal performance. The results show that the avian hippocampus is also active during recall of a learned spatial task, but the activation is significantly lower than in animals learning actually. As in previous experiments, hippocampal IEG expression showed strong variation not only in the position of the active patches of neurons, but also in size and cell density. The observed difference contributes to the view that immediate early genes may not be indicators of activation alone, but may be due to a combination of activation and plastic changes.
