Segregation of study items in memory determines the magnitude and direction of directed forgetting

When words at study are divided into to‐be‐remembered and to‐be‐forgotten ones, people recall more of the former than of the latter in a surprise memory test for all words. In this study, we also tapped memory for word identity at study (forget or remember) by asking participants to reproduce in memory selected portions of the original words. We found word identity to be parasitic on word reproduction. As a result, there is a noted tendency to recall forget‐words from study as remember‐words in the memory test more than vice versa.     

Emotion regulation in violent conflict: reappraisal, hope, and support for humanitarian aid to the opponent in wartime

It is well known that negative intergroup emotions such as anger, fear, and hatred play a major role in initiating and maintaining intergroup conflicts. It is far less clear, however, what factors promote the resolution of intergroup conflicts. Using an emotion regulation- framework, we hypothesised that one form of emotion regulation-namely cognitive reappraisal-should play a salutary role in such conflicts, and be associated with increased hope as well as greater support for humanitarian aid to out-group members. To test these hypotheses, we used a nationwide survey of Jewish-Israeli adults, conducted during the war in Gaza between Israelis and Palestinians. Results obtained via structural equation modelling revealed that Israelis who regulated their negative emotions during the war through reappraisal were more supportive in providing humanitarian aid to innocent Palestinian citizens and that this relation was partially mediated by an enhanced feeling of hope.     

Effects of Humor on Intergroup Communication in Intractable Conflicts: Using Humor in an Intergroup Appeal Facilitates Stronger Agreement Between Groups and a Greater Willingness to Compromise

Overcoming sociopsychological barriers within intergroup communications may bring forth new, practical methods for conflict resolution, particularly crucial for groups engulfed by intractable conflict. This article examines the use of humor—an extremely effective technique of persuasive communication—as one potential route whose potency in resolving intractable conflicts has thus far been neglected. In Study 1, Palestinians who read a message from an “Israeli representative” (conveying the Israeli narrative of the conflict) agreed more with the Israeli perspective once three short humorous asides were added to the original statement. When these humorous asides targeted Jewish‐Israelis, Palestinian‐Israeli participants were more willing to compromise on various aspects of the conflict. In Study 2, Jewish‐Israelis who read a message from a “Palestinian representative” were more agreeable to the Palestinian message (portraying the Palestinian narrative) once three short humorous asides were added to the original statement. When these humorous asides were general in nature (but not when they targeted Palestinian‐Israelis), Jewish‐Israeli participants were more willing to compromise on various aspects of this intractable conflict. These findings further demonstrate the power of psychological barriers in intractable conflicts and the potential of humor to overcome them. Implications and limitations of the current research are discussed.

Measuring attention in the hemispheres: the lateralized attention network test (LANT)

The attention network test (ANT) is a brief computerized battery measuring three independent behavioral components of attention: Conflict resolution (ability to overcome distracting stimuli), spatial Orienting (the benefit of valid spatial pre-cues), and Alerting (the benefit of temporal pre-cues). Imaging, clinical, and behavioral evidence demonstrate hemispheric asymmetries in these attentional networks. We constructed a lateralized version of the ANT (LANT), with brief targets flashed in one or the other visual hemifield. We also modified the tests by including invalid spatial cues in order to measure the cost component of Orienting. In a series of experiments, we investigated the efficiency of the attention networks separately in each hemisphere. Participants exhibited significant estimates of all networks measured by the LANT, comparable to the ANT. The three networks were represented in each hemisphere separately and were largely comparable across the two hemispheres. We suggest that the LANT is an informative extension of the original ANT, allowing for measurement of the three attention networks in each hemisphere separately.     

Its own reward: lessons to be drawn from the reversed-reward contingency paradigm

This is a review of the reversed-reward contingency (RRC) paradigm in animals and the cognitive functions on which it is founded. I shall present the RRC basic paradigm and the ensuing modifications it underwent, the animals tested, the results obtained and the analyses offered within the literature. Then I would the claim that RRC is a case of a compound cognitive behavior, one that is the result of interactions between three other cognitive functions: crude numerical assessment and economic choice (uniting value assignment and behavioral inhibition). I will present data concerning these three fields and will demonstrate how they are both affecting and affected by the findings of the RRC scheme. RRC is treated here as a test case for a broader type of analysis, one which, hopefully, will show that in order to fully understand composite and complex behavior we need to meticulously explore its building blocks and their dynamic interplay.

Appearance of symmetry, beauty, and health in human faces

Symmetry is an important concept in biology, being related to mate selection strategies, health, and survival of species. In human faces, the relevance of left-right symmetry to attractiveness and health is not well understood. We compared the appearance of facial attractiveness, health, and symmetry in three separate experiments. Participants inspected front views of faces on the computer screen and judged them on a 5-point scale according to their attractiveness in Experiment 1, health in Experiment 2, and symmetry in Experiment 3. We found that symmetry and attractiveness were not strongly related in faces of women or men while health and symmetry were related. There was a significant difference between attractiveness and symmetry judgments but not between health and symmetry judgments. Moreover, there was a significant difference between attractiveness and health. Facial symmetry may be critical for the appearance of health but it does not seem to be critical for the appearance of attractiveness, not surprisingly perhaps because human faces together with the human brain have been shaped by adaptive evolution to be naturally asymmetrical.     

Effect of neurofeedback on hemispheric word recognition

We applied SMR/theta neurofeedback (NF) training at central sites of 20 Israeli children aged 10-12 years, half boys and half girls. Half of the subjects received C3 training and the other half C4 training, consisting of 20 half-hour sessions. We assessed the effects of training on lateralized lexical decision in Hebrew. The lateralized lexical decision test reveals an independent contribution of each hemisphere to word recognition (Barnea, Mooshagian, & Zaidel, 2003). Training increased accuracy and sensitivity. It increased left hemisphere (LH) specialization under some conditions but it did not affect interhemispheric transfer. Training did affect psycholinguistic processing in the two hemispheres, differentially at C3 and C4. Training also increased hemispheric independence. There were surprising sex differences in the effects of training. In boys, C4 training improved LH accuracy, whereas in girls C3 training improved LH accuracy. The results suggest that the lateralized NF protocol activates asymmetric hemispheric control circuits which modify distant hemispheric networks and are organized differently in boys and girls.
