Proactive interference from items previously stored in visual working memory

This study investigates the fate of information that was previously stored in visual working memory but that is no longer needed. Previous research has found inconsistent results, with some showing effective release of irrelevant information and others showing proactive interference. Using change detection tasks of colors or shapes, we show that participants tend to falsely classify a changed item as "no change" if it matches one of the memory items on the preceding trial. The interference is spatially specific: Memory for the preceding trial interferes more if it matches the feature value and the location of a test item than if it does not. Interference results from retaining information in visual working memory, since it is absent when items on the preceding trials are passively viewed, or are attended but not memorized. We conclude that people cannot fully eliminate unwanted visual information from current working memory tasks.     

Being the same and different: A model explaining new product adoption

• The study suggests an alternative conceptualization for understanding adoption behavior over time, based on Optimal Distinctiveness Theory. This theory states that social identity derives from a fundamental tension between human needs for validation and similarity to others—the need for assimilation—and a countervailing need for uniqueness and individuation—the need for differentiation. The present study proposes that the effect of the size of the group of consumers who have already adopted a new product on an individual consumer's decision to adopt this product is contingent upon the consumer's two predispositions: the need for assimilation and the need for distinctiveness. Results of empirical research suggested that differently perceived subgroup sizes fulfill consumers' dual needs for distinctiveness and assimilation differently. The influence of the adopters' group size on a consumer's decision to adopt a new product varied among individuals with different levels of needs for distinctiveness and assimilation: when need for distinctiveness was low, the higher was the need for assimilation and the larger was the perceived group size, the higher was the probability of adopting the product. When the need for distinctiveness was high, the lower was the need for assimilation and the larger was the perceived group size, the lower was the probability of adopting the product. In addition, when the need for both distinctiveness and assimilation were high, the probability of adopting the product rose as the perceived group size increased. Implications for product variation, marketing communication, and target groups are discussed.

The necessity of observing real life situations: Palestinian‐Israeli violence as a laboratory for learning about social behaviour

Social psychology emerged in the early part of the last century as a distinct discipline that focused on the study of social behaviour of individuals and collectives. Over time, however, social psychology has relatively ignored the ‘social’ part of the equation and has become mainly concerned with individual behaviour. The major part of social psychological research was carried out in the artificial context of the experimental laboratory. Studying social behaviour in real life contexts is essential, not only to return social psychology to its roots, but also to ensure that our contributions are both theoretically rich and socially valuable. Observation of real life situations is essential if we want to advance our understanding of how individuals and collectives behave. To illustrate the importance of a contextually rich social psychology and the usefulness of natural observations, the recent violent confrontation between the Israelis and the Palestinians is described and analysed, focusing on social behaviours of Israeli Jews. In conclusion, it is argued that social psychology should strive towards equilibrium between natural and experimental approaches, between personal and contextual emphases and between micro and macro perspectives.

Teachers' Conservatism, Openness to Change, Transcendence and Self-Enhancement in Daily Life and in School Situations

In the present study we examined conservatism, openness to change, transcendence and self-enhancement as reflected in the relationships among teachers' values, attitudes and behaviors that presumably share common motivations, in daily life as well as in school situations. It is assumed that values cannot be fully understood and meaningfully measured without reference to the attitudes and behaviors which express them. In this study we hypothesized that the relationships among values as expressed in Schwartz's theory (e.g., 1992), also guide relationships among the respective attitudes and behaviors. We expected more consistency among values, attitudes and behaviors in daily-life as compared to school situations. Participants were 130 Israeli female teachers. Findings revealed compatibility between values and attitudes sharing common motivations and partial but nevertheless lawful relationships between values, attitudes and behaviors. We found that teachers' conservative behavior in daily life and their openness to change and transcendence in school situations were explained both by values and attitudes. However, attitudes were mediators between values and behaviors only with regard to conservatism in daily life and openness to change in school situations. We also found that across the motivational themes, values explained behaviors in daily life situations whereas attitudes explained behaviors in school situations.     

Meaning in learning: Contextual cueing relies on objects’ visual features and not on objects’ meaning

People easily learn regularities embedded in the environment and utilize them to facilitate visual search. Using images of real-world objects, it has been recently shown that this learning, termed contextual cueing (CC), occurs even in complex, heterogeneous environments, but only when the same distractors are repeated at the same locations. Yet it is not clear what exactly is being learned under these conditions: the visual features of the objects or their meaning. In this study, Experiment 1 demonstrated that meaning is not necessary for this type of learning, as a similar pattern of results was found even when the objects’ meaning was largely removed. Experiments 2 and 3 showed that after learning meaningful objects, CC was not diminished by a manipulation that distorted the objects’ meaning but preserved most of their visual properties. By contrast, CC was eliminated when the learned objects were replaced with different category exemplars that preserved the objects’ meaning but altered their visual properties. Together, these data strongly suggest that the acquired context that facilitates real-world objects search relies primarily on the visual properties and the spatial locations of the objects, but not on their meaning.     

The Thrill of Creative Effort at Work: An Empirical Study on Work,Creative Effort and Well-Being

The connections between creative effort at work and four measures of subjective well-being are studied using data on a sample of 922 Jewish Israeli adults who are salaried employees. The paper finds that self-reported creative effort aimed at making work more enjoyable is positively associated with global evaluation of life; with purpose and meaning in life, and with positive emotions. No significant link with negative emotions was found. This study also finds significant associations with three additional intrinsic features of work-creative tasks; independence at work and intellectual work-and various measures of subjective well-being, even when controlling for age, gender, marital status, having children, education, time worked, financial satisfaction, subjective health and religiosity. The robustness of the links between intrinsic features of work and subjective well-being demonstrate that work serves not only as a means to material ends, but also as a direct source of personal happiness, meaning and satisfaction.     

Functional connectivity dynamics during film viewing reveal common networks for different emotional experiences

Recent theoretical and empirical work has highlighted the role of domain-general, large-scale brain networks in generating emotional experiences. These networks are hypothesized to process aspects of emotional experiences that are not unique to a specific emotional category (e.g., “sadness,” “happiness”), but rather that generalize across categories. In this article, we examined the dynamic interactions (i.e., changing cohesiveness) between specific domain-general networks across time while participants experienced various instances of sadness, fear, and anger. We used a novel method for probing the network connectivity dynamics between two salience networks and three amygdala-based networks. We hypothesized, and found, that the functional connectivity between these networks covaried with the intensity of different emotional experiences. Stronger connectivity between the dorsal salience network and the medial amygdala network was associated with more intense ratings of emotional experience across six different instances of the three emotion categories examined. Also, stronger connectivity between the dorsal salience network and the ventrolateral amygdala network was associated with more intense ratings of emotional experience across five out of the six different instances. Our findings demonstrate that a variety of emotional experiences are associated with dynamic interactions of domain-general neural systems.     

Sense of Coherence During Female Holocaust Survivors’ Formative Years

Four female Holocaust survivors were interviewed in order to investigate how they coped prior to the Holocaust, during the Holocaust years, following the end of World War II, and during integration within emerging Jewish society prior to the establishment of the State of Israel. Antonovsky’s (1987 Antonovsky, A. (1987). Unraveling the mystery of health: How people manage stress and stay well. San Francisco, CA: Jossey-Bass. [Google Scholar]) concept of sense of coherence (SOC) and thematic analysis were employed. The analysis suggests that their ability to navigate these life-changing circumstances as young women was the result of the elasticity of the SOC components and the meanings ascribed to them, depending on the situations encountered.
