Pip and pop: nonspatial auditory signals improve spatial visual search

Searching for an object within a cluttered, continuously changing environment can be a very time-consuming process. The authors show that a simple auditory pip drastically decreases search times for a synchronized visual object that is normally very difficult to find. This effect occurs even though the pip contains no information on the location or identity of the visual object. The experiments also show that the effect is not due to general alerting (because it does not occur with visual cues), nor is it due to top-down cuing of the visual change (because it still occurs when the pip is synchronized with distractors on the majority of trials). Instead, we propose that the temporal information of the auditory signal is integrated with the visual signal, generating a relatively salient emergent feature that automatically draws attention. Phenomenally, the synchronous pip makes the visual object pop out from its complex environment, providing a direct demonstration of spatially nonspecific sounds affecting competition in spatial visual processing.     

Maternal ratings of infant regulatory competence from 6 to 12 months: influence of perceived stress, birth-weight, and intervention: a randomized controlled trial

Mothers’ reports of preterm and term infants’ temperament from 6 to 12 months of age were studied, with intervention and stress as predictors. Preterm infants with a birth weight <2000 g were randomized to an intervention (71) or a control (69) group. A control group of healthy term infants (74) was also established. The intervention was a modified version of the “Mother–Infant Transaction Program”, aimed at sensitizing caregivers to the infants’ individual characteristics. Temperament was measured with the Infant Behavior Questionnaire, and stress with the Parenting Stress Index. There were no group differences in temperament at 6 or 12 months or in change during the same period. There was a strong association between stress and negative reactivity in the preterm control group at 12 months. In the preterm intervention group, there were strong negative correlations between stress and regulatory competence at 6 months. The intervention seemed to change the relationship between stress and temperament. The strength of this association indicates that the intervention sensitized mothers to the temperamental regulatory competence of their preterm infants.     

European norms and equations for a two dimensional presentation of values as measured with Schwartz's 21‐item portrait values questionnaire

The present study utilizes European Social Survey (ESS) data to introduce European norms and equations for computation of the Self‐Transcendence—Self‐Enhancement and Conservation—Openness to Change value dimensions, as measured with the 21‐item Portrait Values Questionnaire (PVQ). Our analysis of ESS round 1 and 2 data suggest that the two‐dimensional structure and the equations based on this structure are extremely robust. Presenting the two value dimensions besides the 10 basic values offers the advantages of (a) heightened reliability, (b) control of response tendency, and (c) possibility to present results in two‐dimensional space.

Self‐esteem and values

The purpose of the present study was to connect personal values to self‐esteem in 14 samples (N = 3612) of pre‐professionals, high school students, and adults, from Finland, Russia, Switzerland, Italy, and Estonia. Self‐enhancement values (power, achievement) and openness to change values (self‐direction, stimulation) were positively, and self‐transcendence values (universalism, benevolence) and conservation values (tradition) were negatively related to self‐esteem. These direct relations between values and self‐esteem were only partly consistent with predictions derived from Maslow's theory of growth and deficiency needs. In samples of pre‐professionals, self‐esteem was correlated with congruence between personal values and the prevailing values environment. On the group‐level, endorsement of achievement and universalism values was more strongly and positively related to self‐esteem in samples where these values were considered more important. In contrast, endorsement of self‐direction and hedonism values was more strongly and positively related to self‐esteem in samples where these values were considered less important. These group‐level results are interpreted as suggesting that attainment of culturally significant goals may raise self‐esteem, but that high self‐esteem may be required for the pursuit of less socially desirable goals.

Perception with compensatory devices: from sensory substitution to sensorimotor extension

Sensory substitution devices provide through an unusual sensory modality (the substituting modality, e.g., audition) access to features of the world that are normally accessed through another sensory modality (the substituted modality, e.g., vision). In this article, we address the question of which sensory modality the acquired perception belongs to. We have recourse to the four traditional criteria that have been used to define sensory modalities: sensory organ, stimuli, properties, and qualitative experience ( Grice, 1962 ), to which we have added the criteria of behavioral equivalence ( Morgan, 1977 ), dedication ( Keeley, 2002 ), and sensorimotor equivalence ( O'Regan & Noë, 2001 ). We discuss which of them are fulfilled by perception through sensory substitution devices and whether this favors the view that perception belongs to the substituting or to the substituted modality. Though the application of a number of criteria might be taken to point to the conclusion that perception with a sensory substitution device belongs to the substituted modality, we argue that the evidence leads to an alternative view on sensory substitution. According to this view, the experience after sensory substitution is a transformation, extension, or augmentation of our perceptual capacities, rather than being something equivalent or reducible to an already existing sensory modality. We develop this view by comparing sensory substitution devices to other "mind-enhancing tools" such as pen and paper, sketchpads, or calculators. An analysis of sensory substitution in terms of mind-enhancing tools unveils it as a thoroughly transforming perceptual experience and as giving rise to a novel form of perceptual interaction with the environment.     

季节性情感障碍存在记忆损伤吗？

季节性情感障碍(Seasonal Affective Disorder, SAD)与轻度到中度的临床抑郁有类似的症状,它通常发生于季节性日照不足的地区。造成该障碍的一个可能原因是褪黑素分泌不足。与非季节性抑郁相比, 季节性抑郁的记忆损伤尚未得到充分研究。以往的研究也发现了一些类似于非季节性抑郁的记忆损伤, 但通常很少达到统计的显著性, 且其采用的测验任务也缺乏分辨力, 未能对损伤进行足够的细节描述。这里对有关文献做一个综述。     

The Net in the Park

Ubiquitous Computing, Pervasive Computing, Physical Computing, Everyware, Tangible User Interface, and the Internet of Things all share the same viewpoint—a viewpoint that sees computers, phones, and game consoles as no longer being the only devices in our environment deemed worthy to embody computation and be connected. Each of these approaches focuses on slightly different aspects of the features and potentialities of the enabling technologies (i.e., Physical Computing focuses on the growing power of microcontrollers; IOT on the increasing influence of tagging systems; Everyware on the pervasiveness of the web through wired and wireless connections, etc.) We understand and place more emphasis on the similarities then the differences among these approaches, and at the same time, we try to address specific human activity issues by exploiting these new enabling technologies and visions. In the paper, we present a project, Wi-roni, that addresses two issues: in-person communication and the added value of being in a given location when accessing a given content. To this end, we considered in some detail the possibilities of three of these enabling technologies: ultrasound sensors, MEMS, and mash-up of Internet application. These technologies were chosen based on the nature of the human activity, and not vice versa. In Wi-roni, an Urban Architecture project located in the La Gora public park in Monteroni d'Arbia, a small village in the province of Siena (Italy), we developed two interconnect solutions: Wi-wave, a column for accessing web audio content in public spaces, and Wi-swing, a children’s swing that tells stories while swinging. These devices represent both the concrete grounds from which to begin to address the abovementioned human activity issues and the playground in which to explore the new, emerging interaction modalities that the enabling technologies could allow.     

Lost in the Sauce: The Effects of Alcohol on Mind Wandering

ABSTRACT— Alcohol consumption alters consciousness in ways that make drinking both alluring and hazardous. Recent advances in the study of consciousness using a mind-wandering paradigm permit a rigorous examination of the effects of alcohol on experiential consciousness and metaconsciousness. Fifty-four male social drinkers consumed alcohol (0.82 g/kg) or a placebo beverage and then performed a mind-wandering reading task. This task indexed both self-caught and probe-caught zone-outs to distinguish between mind wandering inside and outside of awareness. Compared with participants who drank the placebo, those who drank alcohol were significantly more likely to report that they were zoning out when probed. After this increase in mind wandering was accounted for, alcohol also lowered the probability of catching oneself zoning out. The results suggest that alcohol increases mind wandering while simultaneously reducing the likelihood of noticing one's mind wandering. Findings are discussed with regard to theories of alcohol and theories of consciousness.
