Witnessing across time: accessing the present from the past and the past from the present

We are used to the idea that trauma in the past interrupts our capacity to grasp the present. But present or recent trauma can have a similar dissociative effect on our capacity to experience the more distant past. Contemporary trauma can rob the past of its goodness, leaving one feeling as if the past is gone, dead, separated from the present. The vitalization of the present by the past or the past by the present requires that experiences be linked across time. These links are created, in both directions, via categories of experience characterized by shared affect (Modell 1990, 2006). Such categories are created, in turn, by metaphor; and the construction of these metaphors across time requires that one be able to occupy self-states in both the past and the present that can then bear witness to one another. Trauma can result in the dissociation of these self-states from one another, leading to a disconnection of present and past.     

Differences between Chinese morphosyllabic and German alphabetic readers in the Stroop interference effect

The goal of our study was to localize the source of the stronger Stroop interference effect found in morphosyllabic readers as compared with alphabetic readers. Twenty-three Chinese and 24 German undergraduate students were tested in a Stroop paradigm with the following stimuli: color patches, colorneutral words (e.g.,friend printed in yellow), incongruent color-associated words (e.g.,blood printed in blue), and incongruent color words (e.g.,yellow printed in blue). Results revealed no differences in German and Chinese students’ response times to color patches. Chinese participants, however, showed longer color naming latencies for neutral words as well as for color words and color-related words. No differences between German and Chinese participants were found when print color latencies for neutral words were subtracted from print color latencies for color words and color-related words. This result does not support theories which suggest that for morphosyllabic readers there is a direct route from orthography to the semantics of a word. We rather argue, with reference to dual route models of reading, that access from print to phonology is faster for morphosyllabic than for alphabetic readers, and therefore interference caused by conflicting phonologies of color name and written word will be stronger in Chinese readers than in German readers.     

Manipulations of start and food locations affect navigation on a foraging task

Rats were able to search multiple food cups in a foraging task and successfully return to a fixed, but not a variable, start location. Reducing the number of food cups to be searched resulted in an improvement in performance in the variable start condition. Performance was better when only one or two food cups had to be visited but was still impaired if the food was not found in the first cup searched. Variable start locations impaired performance when only one food cup had to be searched, if that cup was moved over the table. These findings suggest that there is an interaction between memory processes and the navigational processes that allows an animal to return to its start location after a foraging trip. It appears that a fixed location for the food or the start point of a foraging trip is a necessary precondition for accurate performance.     

Passion, craving, and affect in online gaming: Predicting how gamers feel when playing and when prevented from playing

According to the Dualistic Model of Passion, two forms of passion can motivate a behavior: harmonious passion and obsessive passion. Across various life activities, studies have found that the two forms of passion show different relationships with affect, linking harmonious passion to positive affect and obsessive passion to negative affect. To investigate if this pattern also holds for online gaming, the present study investigated 160 gamers involved in playing massively multiplayer online role-playing games (MMOs) and examined positive and negative affect (a) when playing and (b) when prevented from playing. In addition, the effects of general affect and craving for playing MMOs were controlled for. Results were as expected from the Dualistic Model of Passion: harmonious passion for online gaming predicted positive affect when playing whereas obsessive passion predicted negative affect when playing and when prevented from playing. Moreover, these effects remained unchanged when general affect and craving were controlled for. With this, the present research shows that individual differences in passion for online gaming explain unique variance in gaming-related emotions. Moreover, the present findings suggests that craving is a variable that future research on positive and negative affect in online gaming should pay closer attention to.

Gift Recipients’ Beliefs About Occasion-based and Nonoccasion-based Gifts: The Importance of Signaling Care and Meeting Expectations in Gift Giving

Most gifts are occasion-based as opposed to nonoccasion-based. That is, most gifts are given in the presence of a special occasion, rather than in the absence of one. Across a series of scenario-based studies, the present research demonstrates that, despite occasion-based gifts being much more common, recipients anticipate that their happiness levels will be quite high when receiving nonoccasion-based gifts, varying little with gift quality. In contrast, they anticipate that their happiness levels will not always be high when receiving occasion-based gifts, varying greatly with gift quality. These diverging outcomes arise because the caliber of gift that is required to signal care and thus meet a recipient’s expectation is much lower for nonoccasion-based gifts than for occasion-based ones. Critically, givers misforecast recipients’ anticipated positive reactions to nonoccasion-based gifts, helping to explain why these gifts are, unfortunately, rather rare.

The relationship between sensory responsiveness profiles,attachment orientations,and anxiety symptoms

Individual variations in the way people respond to sensory stimuli can sometimes lead to maladaptive representations of the world. Indeed, sensory responsiveness profiles were found to be associated with mood symptoms such as depression and anxiety. The goal of the current study was to investigate whether attachment orientations can account for the relationship between sensory responsiveness profiles and anxiety symptoms. Participants (N = 194) completed a battery of questionnaires assessing sensory responsiveness profiles, attachment orientations, and anxiety symptoms. As expected, various associations between sensory responsiveness profiles and anxiety symptoms were accounted for by attachment anxiety and avoidance. We suggest a possible causal path, in which early‐developing sensory responsiveness profiles lead to attachment insecurities, which in turn may lead to mood symptoms such as anxiety.
