Scrutinizing visual images: The role of gaze in mental imagery and memory

Gaze was monitored by use of an infrared remote eye-tracker during perception and imagery of geometric forms and figures of animals. Based on the idea that gaze prioritizes locations where features with high information content are visible, we hypothesized that eye fixations should focus on regions that contain one or more local features that are relevant for object recognition. Most importantly, we predicted that when observers looked at an empty screen and at the same time generated a detailed visual image of what they had previously seen, their gaze would probabilistically dwell within regions corresponding to the original positions of salient features or parts. Correlation analyses showed positive relations between gaze’s dwell time within locations visited during perception and those in which gaze dwelled during the imagery generation task. Moreover, the more faithful an observer’s gaze enactment, the more accurate was the observer’s memory, in a separate test, of the dimension or size in which the forms had been perceived. In another experiment, observers saw a series of pictures of animals and were requested to memorize them. They were then asked later, in a recall phase, to answer a question about a property of one of the encoded forms; it was found that, when retrieving from long-term memory a previously seen picture, gaze returned to the location of the part probed by the question. In another experimental condition, the observers were asked to maintain fixation away from the original location of the shape while thinking about the answer, so as to interfere with the gaze enactment process; such a manipulation resulted in measurable costs in the quality of memory. We conclude that the generation of mental images relies upon a process of enactment of gaze that can be beneficial to visual memory.     

The repertoire and intentionality of gestural communication in wild chimpanzees

A growing body of evidence suggests that human language may have emerged primarily in the gestural rather than vocal domain, and that studying gestural communication in great apes is crucial to understanding language evolution. Although manual and bodily gestures are considered distinct at a neural level, there has been very limited consideration of potential differences at a behavioural level. In this study, we conducted naturalistic observations of adult wild East African chimpanzees (Pan troglodytes schweinfurthii) in order to establish a repertoire of gestures, and examine intentionality of gesture production, use and comprehension, comparing across manual and bodily gestures. At the population level, 120 distinct gesture types were identified, consisting of 65 manual gestures and 55 bodily gestures. Both bodily and manual gestures were used intentionally and effectively to attain specific goals, by signallers who were sensitive to recipient attention. However, manual gestures differed from bodily gestures in terms of communicative persistence, indicating a qualitatively different form of behavioural flexibility in achieving goals. Both repertoire size and frequency of manual gesturing were more affiliative than bodily gestures, while bodily gestures were more antagonistic. These results indicate that manual gestures may have played a significant role in the emergence of increased flexibility in great ape communication and social bonding.     

Explaining Variability: Numerical Representations in 4- to 8-Year-Old Children

The present study aims to examine relations between number representations and various sources of individual differences within early stages of development of number representations. The mental number line has been found to develop from a logarithmic to a more linear representation. Sources under investigation are counting skills and executive functions and are set out against mental number lines from 0 to 10 and 0 to 100 in a sample of 4- to 8-year-old children (N = 80). Findings indicate that counting skills, inhibition, and updating are the most important predictors of the shape of the mental number line over and above age-related developmental differences, with number lines from 0 to 10 being linear to a large extent and number lines from 0 to 100 developing from a random pattern toward logarithmic representations. The shape of the mental number line was found to predict scores on the number comparison task only on the smaller-scale comparison task.     

Work engagement during life-span: The role of interaction outside the organization and task significance

Growing proportion of older employees in the workforce has pushed scholars and managers to examine the changes of individual work-related attitudes and behavior during the life-span and accordingly reconsider work design to sustain the engagement of aging workforces. This study contributes to ambiguous previous findings by investigating age–work engagement linkage and moderating effects of such job characteristics as employees' perceived task significance and interaction outside organization. Survey of bank employees revealed an overall positive linear effect of age on work engagement; task significance was further positively related to work engagement. Although the direct impact of interaction outside the organization to work engagement was not found, the interaction outside the organization moderated the relationship between age and work engagement: older employees with more external interactions reported higher engagement levels than older employees with fewer interactions. Work engagement was highest for older employees who experienced more interaction outside the organization, or perceived their work as significant or both. There was no positive effect of age on work engagement for employees with both lower levels of interaction outside organization and lower task significance.     

The Price of a Piece of Cheese: Value from Fit Between Epistemic Needs and a Learning Versus an Outcome Focus

In decision making, people can focus on decisional outcomes (outcome focus), but they can also focus on gaining knowledge about the decisional domain (learning focus). Furthermore, people differ in the strength of their epistemic needs—their preference for developing a rich and accurate understanding of the world. We invoke the regulatory fit theory to predict that higher epistemic needs better fit a learning focus than lower epistemic needs, resulting in a greater increase in valuation of the chosen option when a learning rather than an outcome focus is induced. This general hypothesis was tested and supported in three studies, each focusing on a different proxy to epistemic needs. Thus, individuals experienced greater value when they had lower expertise (Study 1), higher need for assessment (Study 2), and higher need for cognition (Study 3) when a learning rather than an outcome focus was induced. Implications for work on epistemic needs, regulatory fit theory, and decision‐making practice are discussed. Copyright © 2011 John Wiley & Sons, Ltd.     

Not so ugly after all: when shame acts as a commitment device

Most psychological theories and research on shame focus on the ugly aspects and negative consequences of this emotion. Theories on moral emotions, however, assume that shame acts as a commitment device motivating prosocial behavior. To solve this apparent paradox, the authors studied the effects of shame on prosocial behavior. Shame was hypothesized to motivate prosocial behavior when it was relevant for the decision at hand (endogenous). In contrast, shame that was not relevant for the decision at hand (exogenous) was hypothesized to have no such effects. Four experiments with three different shame inductions and two different measures of prosocial behavior confirmed that endogenous shame motivated prosocial behavior for proselfs but that exogenous shame did not. Shame is shown to have a clear interpersonal function in the sense that it acts as a commitment device.     

The Hermeneutical Agenda: Between Text and Reader

This paper addresses a specific chapter of Rollins' book in an attempt to critique the hermeneutical issue raised throughout his volume but particularly in chapter six. This issue is focused in a new way in Soul and Psyche, as it describes the history and possibilities of employing psychology as a new methodological screen with which to read and interpret the Bible.     

Psychometric evaluation and experimental validation of the statistics anxiety rating scale

The Statistics Anxiety Rating Scale (STARS) was adapted into German to examine its psychometric properties (n = 400). Two validation studies (n = 66, n = 96) were conducted to examine its criterion-related validity. The psychometric properties of the questionnaire were very similar to those previously reported for the original English version in various countries and other language versions. Confirmatory factor analysis indicated 2 second-order factors: One was more closely related to anxiety and the other was more closely related to negative attitudes toward statistics. Predictive validity of the STARS was shown both in an experimental exam-like situation in the laboratory and during a real examination situation. Taken together, the findings indicate that statistics anxiety as assessed by the STARS is a useful construct that is more than just an expression of a more general disposition to anxiety.     

The exemplary social emotion guilt: Not so relationship-oriented when another person repairs for you

Guilt is considered by many researchers to be the hallmark social emotion. Guilt theories perceive guilt to be a negative emotion with positive interpersonal consequences, and empirical research has shown guilt to motivate prosocial behaviours aimed at restoring the relationship with one's victims. The current research questions the relationship-oriented nature of this emotion. Five experiments reveal that when a person repairs the transgressor's damage caused to a victim, the transgressor's guilt feelings, reparative intentions, and prosocial behaviour decrease. These findings suggest that it is not the relationship with the victim that is important in the regulation of guilt feelings, but rather the reparative actions that have been undertaken. Implications for theory and behavioural research on guilt are discussed.
