Event-related potential and behavioural evidence of goal-based expectations for consistent actions among group members.

ABSTRACT: People expect group members to act consistently. However, because actions are organized hierarchically, incorporating deep-level goals and shallow-level movements, it remains unclear what level of action is expected to be consistent among group members. We determined that these two levels of action representations can be dissociated in object-directed actions and measured the late positive potential (LPP), which indicates expectation.

Sedimentary and diagenetic characteristics of the Z21 field in the Huizhou depression, Pearl River Mouth basin, South China Sea.

The Huizhou Depression in the Pearl River Mouth basin has prospective hydrocarbon potential, with Miocene sandstones as its main oil and gas-bearing reservoir. The sandstones in Miocene formation of the Z21 offshore oil-gas field composed of medium-grained, moderately sorted subarkose and lithic arkose. In this study, a total of six depositional lithofacies, namely Massive fine- to medium-grained sandstone (Sm), ripple cross-laminated fine-grained sandstone (Sr), parallel-laminated siltstone and claystone (Fl), lenticular siltstone (Sl), parallel-bedded fine-grained sandstone (Sp), wavy laminated siltstone (Sw), and two depositional systems, namely nearshore sand bar (SB) and sand sheet (SS) were identified based on core observations and seismic study.

The spatial distance compression effect is due to social interaction and not mere configuration.

In recent years, there has been a surge of interest in perception, evaluation, and memory for social interactions from a third-person perspective. One intriguing finding is a spatial distance compression effect when target dyads are facing each other. Specifically, face-to-face dyads are remembered as being spatially closer than back-to-back dyads.

Symbolic Product Superiority in the Neural Salience of Compensatory Consumption Behavior.

To cope with self-threat being induced by personal setbacks in daily life, compensatory consumption, especially on symbolic product, has been found to do valuable help to resolve discrepancies between ideal and actual self-concept. Conforming to symbolic self-completion theory, the current study adopted event-related potentials to explore the objective information processing stages in self-concept-impaired status (the defeat group) on a neural level. The behavioral results replicated previous findings that the defeat group gained stronger purchase intention for symbolic products than utilitarian products.

Behavioral Intention Promotes Generalized Reciprocity: Evidence From the Dictator Game.

Generalized reciprocity is the phenomenon that individuals treat others in the same way that others treated them in the past. Besides the behavioral outcomes, whether intention information also manipulates generalized reciprocal behavior remains unclear. By conducting two rounds of the dictator game, the current research investigated the influence from the dictator's intention on the receiver's following resource allocation performance.

Incidental learning of group trust: Predictive gaze cue matters.

Human gaze is a subtle cue to deliver information and helps impression formation in social interactions. People automatically follow the gaze direction of others and shift their attention accordingly, as well as determine the trustworthiness of others based on the predictable validity of their gaze behavior, yet it remains unclear how this works at the collective level. Therefore, the current study is the first to explore the incidental learning of trust from a group's gaze behavior.

Things Become Appealing When I Win: Neural Evidence of the Influence of Competition Outcomes on Brand Preference.

Against the background of an increasingly competitive market environment, the current study aimed to investigate whether and how victory and defeat, as two critical factors in competition outcomes, would affect consumers' preference of unfamiliar brands. In the experiment, participants' status of victory or defeat was induced by a pseudo-online game, followed by a main task of brand preference rating. Using the precise and intuitive attributes of neuroscientific techniques, we adopted event-related potentials to analyze brain activity precisely during brand information processing when individuals experienced victory or defeat.

Humans Conceptualize Victory and Defeat in Body Size.

Size matters considerably for victory and defeat during competitive situations. Drawing on the embodied theory of cognition, we examined the reciprocal association between size and competition outcomes. To do so, we used the 'rock-paper-scissors game', whose outcome is not contingent on apparent physical size.

Acidic Zeolite L as a Highly Efficient Catalyst for Dehydration of Fructose to 5-Hydroxymethylfurfural in Ionic Liquid.

Zeolite L was synthesized by the hydrothermal method and post-treated by NH exchange to adjust its acidity. The samples were systematic characterized by various techniques including XRD, X-ray fluorescence spectroscopy, N adsorption-desorption, scanning electron microscopy, pyridine IR spectroscopy, and NH temperature-programmed desorption. The results demonstrated that the NH -exchange post-treatment increased the surface area, micropore volume, and acidity of zeolite L.

Perceiving crowd attention: Gaze following in human crowds with conflicting cues.

People automatically redirect their visual attention by following others' gaze orientation, a phenomenon called "gaze following." This is an evolutionarily generated socio-cognitive process that provides people with information about their environments. Often, however, people in crowds can have rather different gaze orientations.

Attentional bias in competitive situations: winner does not take all.

Compared to previous studies of competition with participants' direct involvement, the current study for the first time investigated the influence of competitive outcomes on attentional bias from a perspective of an onlooker. Two simple games were employed: the Rock-Paper-Scissors game (Experiment 1) in which the outcome is based on luck, and Arm-wrestling (Experiment 2), in which the outcome is based on the competitors' strength. After observing one of these games, participants were asked to judge a stimulus presented on either the winner's or loser's side of a screen.

How to break the configuration of moving objects? Geometric invariance in visual working memory.

Visual working memory is highly sensitive to global configurations in addition to the features of each object. When objects move, their configuration varies correspondingly. In this study, we explored the geometric rules governing the maintenance of a dynamic configuration in visual working memory.

4-(Cyclo-propane-carboxamido)-benzoic acid.

In the title compound, C(11)H(11)NO(3), the dihedral angle between the benzene ring and the cyclo-propane ring is 63.2 (1)°. In the crystal, mol-ecules are linked through classical cyclic carb-oxy-lic acid O-H⋯O hydrogen-bond inter-actions [graph set R(2) (2)(8)] giving centrosymmetric dimers which are extended along the b-axis direction through amide N-H⋯O hydrogen-bond inter-actions, giving one-dimensional ribbon structures.

Cytotoxic alkoxylated xanthones from the resin of Garcinia hanburyi.

Three new xanthones, garcinolic acid (1), 10α-ethoxy-9,10-dihydromorellic acid (2), and 10α-ethoxy-9,10-dihydrogambogenic acid (3), along with six known compounds were isolated from the resin of Garcinia hanburyi. These compounds were tested for their cytotoxicities against A549, HCT116, SK-BR-3 and HepG2, and showed high inhibitory effects on the cell lines.

The perceptual root of object-based storage: an interactive model of perception and visual working memory.

Mainstream theories of visual perception assume that visual working memory (VWM) is critical for integrating online perceptual information and constructing coherent visual experiences in changing environments. Given the dynamic interaction between online perception and VWM, we propose that how visual information is processed during visual perception can directly determine how the information is going to be selected, consolidated, and maintained in VWM. We demonstrate the validity of this hypothesis by investigating what kinds of perceptual information can be stored as integrated objects in VWM.
