Perception of acoustically presented time series with varied intervals

Data from three experiments on serial perception of temporal intervals in the supra-second domain are reported. Sequences of short acoustic signals (“pips”) separated by periods of silence were presented to the observers. Two types of time series, geometric or alternating, were used, where the modulus 1 + δ of the inter-pip series and the base duration T_b (range from 1.1 to 6 s) were varied as independent parameters. The observers had to judge whether the series were accelerating, decelerating, or uniform (3 paradigm), or to distinguish regular from irregular sequences (2 paradigm). “Intervals of subjective uniformity” (isus) were obtained by fitting Gaussian psychometric functions to individual subjects' responses. Progression towards longer base durations (T_b = 4.4 or 6 s) shifts the isus towards negative δs, i.e., accelerating series. This finding is compatible with the phenomenon of “subjective shortening” of past temporal intervals, which is naturally accounted for by the lossy integration model of internal time representation. The opposite effect observed for short durations (T_b = 1.1 or 1.5 s) remains unexplained by the lossy integration model, and presents a challenge for further research.     

Liking Violence and Action: An Examination of Gender Differences in Children's Processing of Animated Content

It is widely assumed that children like violence in cartoons, but this assumption has not been supported in existing studies that show nonviolent programs are liked just as much or more than violent programs. The present experiment extended enjoyment of media violence research by testing whether violence and action (independently manipulated) influenced children's liking of slapstick cartoons. We also proposed a path model to test potential indirect effects of violence and action on liking. Using animation software, four versions of a slapstick cartoon were created that varied in terms of violence (present, absent) and action (high, low). A total of 128 elementary school children watched one of the four versions of the program. Violence had no direct effect on the liking of the cartoon, but did indirectly decrease liking for males by decreasing boys' wishful identification with the anthropomorphized characters. Action increased liking for males but not for females.     

A religious perspective on climate change

The aim of this article is to argue that religions can contribute to fight climate change. It is argued that religions can contribute with ethics. Religions can contribute with reflections concerning fundamental ethical principles as well as practical ethical instructions concerning sustainable lifestyles. But it is also argued that religions can contribute with a world-view that underpins ethics in a very fruitful way. We can want to protect the world because it is beautiful, not simply because it is useful. A religious worldview is articulated very clearly in praise and celebration. Here all of creation is praised and celebrated as the works of an all loving God or Spirit. This implies that the universe, planet Earth and all life on it are seen as creations which all have an intrinsic value. They are not just accidental matter or means for human beings, but magnificent creations which are commendable in themselves, no matter what their utility value may be. According to this religious interpretation ethics are thus grounded in a cosmic love. The motivation for taking care of the environment is love and not rational calculation and duty. A motivation based on positive, elevated feelings such as love, respect, devotion and an experience of beauty is much more vigorous than a motivation based on cool calculations and cold-hearted duty. Religion can engage people at a deeper level than economics and policy, and a deep engagement is extremely important for the success of fighting climate changes, because it is going to take decades.     

Understanding and Integrating Multiple Science Texts: Summary Tasks are Sometimes Better Than Argument Tasks

One of the major challenges of a knowledge society is that students as well as other citizens must learn to understand and integrate information from multiple textual sources. Still, task and reader characteristics that may facilitate or constrain such intertextual processes are not well understood by researchers. In this study, we compare the effects of summary and argument essay tasks when undergraduates read seven different texts on a particular scientific topic, finding that an instruction to write summaries may lead to better understanding and integration than an instruction to write argument essays. We discuss several possible explanations for this result. We also found that beliefs about the certainty of knowledge in some instances can moderate the effect of task on comprehension performance.     

Reading the hippocampal code by theta phase-locking

Both the prefrontal cortex and the hippocampus are crucial for memory encoding and recall. However, it remains unclear how these brain regions communicate to exchange information. Recent findings using simultaneous recordings from the hippocampus and prefrontal cortex of the behaving rat have demonstrated that prefrontal cells' firing is phase-locked to the hippocampal theta rhythm. This suggests that phase synchronization clocked by the theta rhythm could be crucial for the communication between hippocampal and prefrontal regions.     

Sustained conscious access to incidental memories in RSVP

In visual search of natural scenes, differentiation of briefly fixated but task-irrelevant distractor items from incidental memory is often comparable to explicit memorization. However, many characteristics of incidental memory remain unclear, including the capacity for its conscious retrieval. Here, we examined incidental memory for faces in either upright or inverted orientation using Rapid Serial Visual Presentation (RSVP). Subjects were instructed to detect a target face in a sequence of 8–15 faces cropped from natural scene photographs (Experiment 1). If the target face was identified within a brief time window, the subject proceeded to an incidental memory task. Here, subjects used incidental memory to discriminate between a probe face (a distractor in the RSVP stream) and a novel, foil face. In Experiment 2 we reduced scene-related semantic coherency by intermixing faces from multiple scenes and contrasted incidental memory with explicit memory, a condition where subjects actively memorized each face from the sequence without searching for a target. In both experiments, we measured objective performance (Type 1 AUC) and metacognitive accuracy (Type 2 AUC), revealing sustained and consciously accessible incidental memory for upright and inverted faces. In novel analyses of face categories, we examined whether accuracy or metacognitive judgments are affected by shared semantic features (i.e., similarity in gender, race, age). Similarity enhanced the accuracy of incidental memory discriminations but did not influence metacognition. We conclude that incidental memory is sustained and consciously accessible, is not reliant on scene contexts, and is not enhanced by explicit memorization.     

Aspects of fear of personal death,levels of awareness,and religious commitment

This study used a multidimensional and multilevel approach to study the relation between fear of death and religious commitment. A multidimensional self-report measure of fear of personal death, four TAT cards known to elicit a relatively high frequency of death themes, and an index of Jewish religious commitment were administered to 178 young male Jewish Israelis. Unidimensional and multidimensional analysis of these measures suggested that Jewish religious commitment is related to a heightened specific sensitivity to death at different levels of awareness.

Evaluating the Utility of MFT Models in the Treatment of Trauma: Implications for Affect Regulation

The purpose of this paper is to discuss polyvagal theory as a theoretical foundation for helping clinicians more effectively treat clients who have experienced major trauma. More specifically, we emphasize that through the use of both modern and post-modern models, marriage and family therapists may use emotion regulation strategies to assist clients in overcoming the negative repercussions of traumatic events. We suggest that the nature of emotional arousal which accompanies trauma alters the physical process by which the body regulates future affective stimuli in ways that are potentially detrimental to human relationships. We then offer a discussion of how a selection of MFT models contain strategies that promote reconnection to self and others that should be utilized with greater precision, ultimately to target the physiological symptoms of trauma-altered emotion regulation processes. Finally, we discuss the need for more specific, process-oriented research that integrates cross-disciplinary theory to contribute to a more intricate and useful understanding of the treatment of trauma in the relational context.
