How does searching for faces among similar-looking distractors affect distractor memory?

Prior research has shown that searching for multiple targets in a visual search task enhances distractor memory in a subsequent recognition test. Three non-mutually exclusive accounts have been offered to explain this phenomenon. The mental comparison hypothesis states that searching for multiple targets requires participants to make more mental comparisons between the targets and the distractors, which enhances distractor memory. The attention allocation hypothesis states that participants allocate more attention to distractors because a multiple-target search cue leads them to expect a more difficult search. Finally, the partial match hypothesis states that searching for multiple targets increases the amount of featural overlap between targets and distractors, which necessitates greater attention in order to reject each distractor. In two experiments, we examined these hypotheses by manipulating visual working memory (VWM) load and target-distractor similarity of AI-generated faces in a visual search (i.e., RSVP) task. Distractor similarity was manipulated using a multidimensional scaling model constructed from facial landmarks and other metadata of each face. In both experiments, distractors from multiple-target searches were recognized better than distractors from single-target searches. Experiment 2 additionally revealed that increased target-distractor similarity during search improved distractor recognition memory, consistent with the partial match hypothesis.

Examining the Interaction between Perceived Cultural Tightness and Prevention Regulatory Focus on Life Satisfaction in Italy

This study aimed to investigate how some specific cultural and personal factors can influence people’s life satisfaction. By embracing an interactionist perspective, we hypothesized that perceiving one’s social environment as culturally tight (greater strength of social norms) can “match” with regulatory prevention focus (focus on safety following guidelines and rules) resulting in increased life satisfaction. This study relied on a cross-sectional design with 472 participants residing in Italy who filled out a questionnaire with self-report measures of perceived cultural tightness of their place of residence, and well-validated measurement scales of prevention focus and life satisfaction. A moderated multiple regression model revealed that regulatory prevention focus moderated the relationship between perceived cultural tightness and life satisfaction in such a way that the relationship was positive in high (vs. low) prevention focus. Therefore, results confirmed our match hypothesis that individuals’ perception of tight social norms where they reside is associated with higher life satisfaction, particularly in those who are highly focused on prevention. These findings provide insight into identifying possible interactions of perceived culture and regulatory focus on subjective well-being within an Italian sample.

Zebrafish parental progeny investment in response to cycling thermal stress and hypoxia: deposition of heat shock proteins but not cortisol.

The maternal match hypothesis predicts that maternal exposure to a stressor may help prepare offspring to cope with the same disturbance in later life. Although there is support for this hypothesis, the signals involved in non-genetic inheritance are unclear. In this study, we tested how adult zebrafish exposure to diel cycles of thermal stress (27-36°C), hypoxia (20-85% dissolved oxygen) or the combined treatment affects maternal and embryonic levels of cortisol and heat shock proteins (HSPs). While parental exposure to the thermal, hypoxic or combined treatment for 2 weeks did not affect whole-body cortisol levels, the combined exposure increased ovarian cortisol levels by 4-fold and reduced embryonic cortisol content by 60%. The combined treatment also elicited 3- and 19-fold increases in embryo transcripts involved in cortisol breakdown (11bhsd2) and export (abcb4), respectively. The thermal stress and combined exposure also elicited marked increases in ovary and embryo hsp70a (20- to 45-fold) and HSP70 (3- to 7-fold), and smaller increases in ovary and embryo hsp90aa and hsp47 (2- to 4-fold) and in embryo HSP90 and HSP47 (2- to 6-fold). In contrast, except for increases in ovary hsp90aa (2-fold) and embryo HSP90 (3-fold), the hypoxia treatment had little effect on HSP expression and transfer. Overall, while the embryonic deposition of HSPs largely paralleled the ovarian cellular stress response, the inverse relationship between ovary and embryo cortisol levels suggests the existence of barriers against cortisol deposition in response to environmental stressors. We conclude that the endocrine and cellular stress responses make stressor-specific and distinct contributions to non-genetic inheritance.

One step ahead of sea anemone invasions with ecological niche modeling: potential distributions and niche dynamics of three successful invasive species

Established non-native sea anemone populations can affect the native community through multiple mechanisms, including predation and competition. The conservation of invaded communities is therefore of great concern, and spatially explicit information is essential for the prevention or early detection of introductions. Here, we used ecological niche modeling to (1) predict areas with invasion risk of 3 successful widespread invasive sea anemone species (Diadumene lineata, Exaiptasia diaphana, and Nematostella vectensis); (2) determine the invasion stage of current non-native occurrences; and (3) test the climatic match hypothesis of invasion success by assessing their environmental niche dynamics. Our results bring new insights to the invasion process of sea anemones, which is relevant considering the scarcity of monitoring efforts, the issues associated with their detection, and the potential ecological effects they generate on invaded communities. First, we provide potential distributions that could help to detect non-native populations early on. Second, we confirm a strong pattern of successful establishment. Finally, we demonstrate that the invasion success of these species has mainly occurred in areas with environmental conditions similar to those from their respective native ranges (i.e. climatic match, niche conservatism).

SeqNet: Learning Descriptors for Sequence-Based Hierarchical Place Recognition

Visual Place Recognition (VPR) is the task of matching current visual imagery from a camera to images stored in a reference map of the environment. While initial VPR systems used simple direct image methods or hand-crafted visual features, recent work has focused on learning more powerful visual features and further improving performance through either some form of sequential matcher / filter or a hierarchical matching process. In both cases the performance of the initial single-image based system is still far from perfect, putting significant pressure on the sequence matching or (in the case of hierarchical systems) pose refinement stages. In this paper we present a novel hybrid system that creates a high performance initial match hypothesis generator using short learnt sequential descriptors, which enable selective control sequential score aggregation using single image learnt descriptors. Sequential descriptors are generated using a temporal convolutional network dubbed SeqNet, encoding short image sequences using 1-D convolutions, which are then matched against the corresponding temporal descriptors from the reference dataset to provide an ordered list of place match hypotheses. We then perform selective sequential score aggregation using shortlisted single image learnt descriptors from a separate pipeline to produce an overall place match hypothesis. Comprehensive experiments on challenging benchmark datasets demonstrate the proposed method outperforming recent state-of-the-art methods using the same amount of sequential information.

자기해석과 추천메시지의 일치성이 제품평가에 미치는 영향: 과시적 제품을 중심으로*

One of the top tech trends spreading through the retail industry is personalization based as input from recommendation agent systems. As the algorithm of recommendation agent systems gradually develops, the influence of recommendation agent systems on consumers’ decision making and consumption behaviors are becoming important to e-commerce. In this situation, recommendation message served as persuasion message. Meanwhile, self-construal refers to the relationship between self and others, which views the self as separate from or as connected with others. People with independent self-construal construe themselves as autonomous and distinct from others, whereas people with interdependent self-construal construe themselves as harmonious and connected with others. Studies on self-construal have shown the effect of self-construal on persuasion. In this point of view, we examines the effect of congruence between self-construal and recommendation message on product evaluation in e-commerce. Based on a number of previous studies, we predicted that the congruence between self-construal and recommendation message have an impact on consumers’ product evaluation. Especially, when self-construal and recommendation message types match, consumers will show more positive product evaluation than when they do not match (hypothesis 1). This research also interested in clarifying the moderating role of product type, especially level of conspicuousness. Specifically, people’s expectations of how others will evaluate their decisions affects consumption choices and decisions (hypothesis 2). To test our hypotheses, we conducted an experiment in which 179 individuals(38.7 of age, 40.7% female) recruited from Amazon Mechanical Turk(MTurk) participated in return for small monetary reward. The current research employed a 2(self-construal: independent vs. interdependent)×2(recommendation message: independent(I) vs. interdependent(We))×2(product type: conspicuous vs. inconspicuous) between-subjects factorial design was conducted. The participants were randomly assigned to four conditions according to the recommendation message(independent vs. interdependent) and product type(conspicuous vs. inconspicuous). On the other hand, self-construal was measured through a scale and classified into independent self-construal and interdependent self-construal based on the median split. As a result, eight conditions were employed for analysis. Next, with regard to the stimulus used in this study, perfume was selected as a conspicuous product that expresses one

Mimicking Transgenerational Signals of Future Stress: Thermal Tolerance of Juvenile Chinook Salmon Is More Sensitive to Elevated Rearing Temperature Than Exogenously Increased Egg Cortisol

Elevated temperatures resulting from climate change are expected to disproportionately affect ectotherms given their biological function has a direct link to environmental temperature. Thus, as climate change leads to rapid increases in water temperatures in rivers, aquatic ectotherms such as fish may be highly impacted. Organisms can respond to these stressors through flexible and rapid phenotypic change induced via developmental and/or transgenerational plasticity. In oviparous species, gravid females may translate environmental stress across generations via increased exposure of eggs to maternally-derived glucocorticoids (i.e., maternal stress), which has been shown to result in diverse phenotypic effects in offspring. Recent studies suggest these phenotypic changes from maternal glucocorticoids may elicit predictive adaptive responses, where offspring exposed to maternal stress may be better prepared for the stressful environment they will encounter (i.e., environmental match hypothesis). We applied the environmental match hypothesis to examine whether a prenatal exogenous increase in egg cortisol may prepare Chinook salmon offspring (Oncorhynchus tshawytscha) to cope with thermal challenges after being reared in chronically elevated temperatures. Specifically, we exposed eggs to aqueous bath of cortisol-dosed (1000ng/mL) or control (0ng/ml) solutions, and then raised both treatments at current (+0°C—contemporary ambient river temperature) or elevated (+3°C—projected future river temperature) thermal regimes. We quantified thermal performance in fish 7-9 month post fertilization using two methods: via critical thermal maximum (CTMax), and energetic responses (in plasma cortisol, glucose, and lactate) to environmentally relevant, but challenging thermal spikes over 3 days. Overall, we found that exposure to elevated rearing temperatures had a large impact on thermal tolerance, where elevated-temperature reared offspring had significantly higher CTMax. In comparison, egg cortisol treatment had little to no clear effects on CTMax and blood energetic response. Our study demonstrates the importance of elevated water temperatures as an inducer of offspring phenotypes (via early developmental cues), and highlights the significance of examining offspring performance in environments with ecologically relevant stressors.

Exposure to exogenous egg cortisol does not rescue juvenile Chinook salmon body size, condition, or survival from the effects of elevated water temperatures.

Climate change is leading to altered temperature regimes which are impacting aquatic life, particularly for ectothermic fish. The impacts of environmental stress can be translated across generations through maternally derived glucocorticoids, leading to altered offspring phenotypes. Although these maternal stress effects are often considered negative, recent studies suggest this maternal stress signal may prepare offspring for a similarly stressful environment (environmental match). We applied the environmental match hypothesis to examine whether a prenatal stress signal can dampen the effects of elevated water temperatures on body size, condition, and survival during early development in Chinook salmon Oncorhynchus tshawytscha from Lake Ontario, Canada. We exposed fertilized eggs to prenatal exogenous egg cortisol (1,000 ng/ml cortisol or 0 ng/ml control) and then reared these dosed groups at temperatures indicative of current (+0°C) and future (+3°C) temperature conditions. Offspring reared in elevated temperatures were smaller and had a lower survival at the hatchling developmental stage. Overall, we found that our exogenous cortisol dose did not dampen effects of elevated rearing temperatures (environmental match) on body size or early survival. Instead, our eyed stage survival indicates that our prenatal cortisol dose may be detrimental, as cortisol‐dosed offspring raised in elevated temperatures had lower survival than cortisol‐dosed and control reared in current temperatures. Our results suggest that a maternal stress signal may not be able to ameliorate the effects of thermal stress during early development. However, we highlight the importance of interpreting the fitness impacts of maternal stress within an environmentally relevant context.

Niche dynamics of two cryptic Prosopis invading South American drylands

Whether or not species track native climatic conditions during invasions (i.e., climate match hypothesis) is fundamental to understand and prevent potential impacts of invasive species. Recent empirical work suggests that climatic mismatches between native and invasive ranges are pervasive. Whether these differences are due to adaptation to new climatic spaces in the invasive range or due to partial filling of the potential climatic space are still subject to debate. Here, we analyze climatic niche dynamics associated with the invasion of the two most common invasive plants in Brazilian semi-arid areas, Prosopis juliflora and Prosopis pallida. These species have been simultaneously introduced in the region, which creates a unique opportunity to compare their niche dynamics during invasion. Given that P. juliflora have a much wider native range size, we expect these species would present different dispersal potentials, which might translate into different unfilling levels. Using an ordination method with kernel smoother and null models, we contrasted climate spaces occupied by each species in both native and invasive ranges. We further used ecological niche models (ENMs) to compare reciprocal predictions of potentially suitable areas. Against our expectation based on differences in native range sizes, climatic niches of P. juliflora and P. pallida overlapped greatly, both in their native and invasive ranges. Our results support niche conservatism during the invasion process. Climatic mismatches among native and invaded ranges were exclusively attributed to unfilling of native climates in the invasive range. Both species showed similar unfilling levels. Likewise, ENMs predicted regions not yet occupied in the invasive range, revealing a potential for further expansion. We discuss colonization time lag and founder effect as potential mechanisms that may have prevented these species to fully occupy their native niches in the invasive range.

Maternal effects are no match for stressful conditions: a test of the maternal match hypothesis in a common zooplankter

Summary Anticipatory parental effects modulate population responses to environmental conditions and so are predicted to play a large role in the responses of organisms to global change. In response to one such aspect of global change, the eutrophication of freshwaters and associated blooms of the toxin‐producing cyanobacteria species Microcystis aeruginosa, the rotifer Brachionus calyciflorus produces larger offspring. We hypothesized that rotifers, with their short generational times, exposed to highly predictable cyanobacteria bloom conditions, may adaptively increase offspring investment and offspring fitness (i.e. the maternal match hypothesis). We explicitly tested the consequences of this differential investment by rearing offspring produced by rotifers reared under Microcystis and the nontoxigenic green alga Chlamydomonas, in a full factorial design, where offspring were raised under the maternal diet or the opposite food source. We measured age‐specific fecundity, survival and population growth rates under these conditions and found that maternal exposure to Microcystis decreased offspring survival and fecundity, regardless of offspring diet. Population growth rates, tested using aster models, differed significantly among maternal and neonate diets, but there was no significant interaction between the two factors. Our evidence thus leads us to reject the maternal match hypothesis in this case of rotifer–toxigenic algal bloom interactions and provides further support that toxigenic algal blooms may have extensive effects on grazer populations in ways that are not evaluated using traditional, single‐generation experimental methods. A lay summary is available for this article.

Do Format Differences in the Presentation of Information Affect Susceptibility to Memory Distortions? The Three-Stage Misinformation Procedure Reconsidered.

To date most studies within the misinformation paradigm have used the visual presentation of a to-be-remembered event that is later tested verbally or visually. However, the well-established encoding specificity hypothesis predicts that congruence between encoding and test phases should lead to fewer memory errors. In Study 1, we examined the susceptibility to misinformation after encoding original information in 1 of 4 different formats: as a film, slides, and as a written or auditory narrative. All participants were tested verbally, and those who encoded original information pictorially (as a video or slides) were more likely to incorrectly accept verbally suggested information. This might be-a consequence of encoding-retrieval format match. In Study 2, using either verbal or pictorial modality during encoding, postevent information, and test (fully crossed design), we partially supported the encoding-retrieval format match hypothesis; however, auditory presentation of original or postevent information modified the effect, showing that a memory trace created after auditory description was the strongest.

Beyond neutral and forbidden links: morphological matches and the assembly of mutualistic hawkmoth-plant networks.

A major challenge in evolutionary ecology is to understand how co-evolutionary processes shape patterns of interactions between species at community level. Pollination of flowers with long corolla tubes by long-tongued hawkmoths has been invoked as a showcase model of co-evolution. Recently, optimal foraging models have predicted that there might be a close association between mouthparts' length and the corolla depth of the visited flowers, thus favouring trait convergence and specialization at community level. Here, we assessed whether hawkmoths more frequently pollinate plants with floral tube lengths similar to their proboscis lengths (morphological match hypothesis) against abundance-based processes (neutral hypothesis) and ecological trait mismatches constraints (forbidden links hypothesis), and how these processes structure hawkmoth-plant mutualistic networks from five communities in four biogeographical regions of South America. We found convergence in morphological traits across the five communities and that the distribution of morphological differences between hawkmoths and plants is consistent with expectations under the morphological match hypothesis in three of the five communities. In the two remaining communities, which are ecotones between two distinct biogeographical areas, interactions are better predicted by the neutral hypothesis. Our findings are consistent with the idea that diffuse co-evolution drives the evolution of extremely long proboscises and flower tubes, and highlight the importance of morphological traits, beyond the forbidden links hypothesis, in structuring interactions between mutualistic partners, revealing that the role of niche-based processes can be much more complex than previously known.

Parents' Estimations of Preschoolers' Number Skills Relate to at-Home Number-Related Activity Engagement

According to Hunt's match hypothesis, the accuracy of parents' beliefs about their children's abilities can influence the nature of the early learning experiences they provide. The present study examined the accuracy of parents' beliefs about their preschoolers' number development and relations to parent-reported frequency of engaging children in number related experiences at home. Parents reported engaging their preschoolers more frequently in conventional numeracy activities, (i.e. counting and identifying numbers) than advanced number-related activities (e.g. arithmetic) at home, though the frequency of advanced activities increased with the development of children's advanced number skills. Parents were most uncertain about their children's advanced number skills, though they demonstrated an overall tendency to overestimate their children's abilities across number tasks. Increased rates of overestimation and decreased rates of underestimation were associated with increased incidences of advanced activity engagement at home. Thus, results suggest guiding parents to understand their own children's numerical understanding in a wide range of number domains could promote more advanced at-home number-related activity engagement.

Extended self: implications for country-of-origin

Purpose– This paper aims to examine country-of-origin (COO) effects from the theoretical angle of extended self and “otherness”. Traditional COO perspectives view COO as an important quality-related, informational cue used to form product evaluations, develop preferences and make purchase decisions.Design/methodology/approach– An experiment was conducted with the COO of a fresh milk product manipulated to examine these predictions. Data were collected from four samples, Americans living in the USA, Americans living in China, Chinese living in China and Chinese living in the USA.Findings– Results found that COO effects were stronger when consumers felt greater animosity toward the foreign country, were more ethnocentric and were less acculturated (i.e. conceptualized as a less expanded self). Additionally, negative product events were interpreted in light of self, in that reactions to an adverse act were stronger when “others” committed the act. American consumers living abroad were more heavily influenced by COO effects, and evidence suggests that this effect occurred because these Americans had a less expanded self than their Chinese counterparts.Originality/value– This study provides a unique angle which leads to a deeper understanding of COO effects which augments the traditional match hypothesis. Specifically, COO effects are stronger, the smaller one’s extended self (greater animosity and ethnocentrism, less acculturation), and that wrongdoings are interpreted in light of self (i.e. reaction to an adverse act is stronger when “others” commit the act). Few studies to date have focused on these factors as layers of armor that consumers use to protect their self and extended self-image in a cross-cultural context.

The Match between Information Control and Motivation in the Online Context

ABSTRACTE‐commerce practitioners have long tried to leverage the technological characteristics of the Internet to facilitate better information seeking and decision making by consumers online. One impressive characteristic of the Internet is that it offers users various degrees of information control on the same medium. The purpose of this study is to investigate the effects of this characteristic on consumers’ decision‐making online. It is hypothesized that, to improve quality of consumers’ decisions, the degree of information control should match the degree of motivation. The rationale is that highly motivated consumers have a strong will to search for relevant information; therefore, a high degree of information control allows them to search as much as they want and thereby improve their decision making. Low‐motivation consumers, on the other hand, are unwilling to search; hence a low degree of information control, which might push high‐quality information, would benefit them. The study employed the methodology of experiment, and involved 171 voluntary participants. The empirical results show that high‐motivation consumers make better decisions when they are given a high degree of information control, compared to when they are in a low information control condition. On the other hand, low‐motivation consumers in a low information control condition perform better than similar consumers in a high‐control condition. The results strongly support the match hypothesis of information control.

Memory as discrimination: A challenge to the encoding–retrieval match principle.

Four experiments contrasted the predictions of a general encoding-retrieval match hypothesis with those of a view claiming that the distinctiveness of the cue-target relationship is the causal factor in retrieval. In Experiments 1, 2, and 4 participants learned the relationships between 4 targets and trios of cues; in Experiment 3 there were 3 targets, each associated with a pair of cues. A learning phase was followed by a cued-recognition task where the correct target had to be identified based on 1 or more of the cues. The main performance measurement was response time. Learning was designed to lead to high accuracy so effects could be attributed to retrieval efficiency rather than to variations in encoding. The nature of the cues and targets was varied across experiments. The critical factor was whether each cue was uniquely associated with the to-be-recalled target. All experiments orthogonally manipulated (a) how discriminative-or uniquely associated with a target-each cue was and (b) the degree of overlap between the cues present during learning and those present at retrieval. The novel finding reported here is that increasing the encoding-retrieval match can hinder performance if the increase simultaneously reduces how well cues predict a target-that is, a cue's diagnostic value. Encoding-retrieval match was not the factor that determined the effectiveness of retrieval. Our findings suggest that increasing the encoding-retrieval match can lead to no change, an increase, or a decrease in retrieval performance.

FAMILY INVOLVEMENT IN CHINESE AND GERMAN SMALL BUSINESSES

The goal of this study was to examine cultural differences in the value of family involvement in German and Chinese small businesses due to their differences in collectivism/individualism. Our analyses, based on a sample of 562 Chinese and German owners, showed that family involvement — measured as the number of family members that work in the business — is higher in China than in Germany. Compared to German business owners, Chinese owners received most of their start-up capital from family members. Moreover, we were interested in whether family involvement is related to the business owner's ability to make use of start-up capital to turn it into business outcomes. Building on existing literature and based on the match hypothesis we hypothesized that the effects of family involvement on business outcomes depend on the cultural values underlying a business. Our analyses revealed that family involvement negatively affected relationships of start-up capital with business outcomes both in China and in Germany. Our study contributes by showing that a negative effect of family involvement on the ability to make use of start-up capital is not only evident in individualistic cultures such as Germany but does also apply to collectivistic Chinese businesses. Practically, owners in both cultures are suggested to develop strategies in order to prevent and overcome negative effects of family involvement on business outcomes. Our results suggest fruitful avenues for future research.

Cellular Modulation of Polymeric Device Surfaces: Promise of Adult Stem Cells for Neuro-Prosthetics

Minimizing the foreign body response is seen as one critical research strategy for implants especially when designed for immune-privileged organs like the brain. The context of this work is to improve deep brain stimulating devices used in a consistently growing spectrum of psychomotor and psychiatric diseases mainly in form of stiff electrodes. Based on the compliance match hypothesis of biocompatibility we present another step forward using flexible implant materials covered with brain cell-mimicking layers. We covered two types of flexible polyimide films with glandular stem cells derived from pancreatic acini. Using real time-PCR and fluorescent immunocytochemistry we analyzed markers representing various cell types of all three germ layers and stemness. The results demonstrate an unchanged differentiation potential of the polyimide fixated cells as measured by mRNA and protein level. Additionally we developed a fibrinous hydrogel coating to protect them against shear forces upon eventual implantation. By repeating previous analysis and additional metabolism tests for all stages we corroborate the validity of this improvement. Consequently we assume that a stem cell-containing cover may provide a native, fully and actively integrating brain-mimicking interface to the neuropil.

On “Feeling Right” in Cultural Contexts

Whether one is in one’s native culture or abroad, one’s personality can differ markedly from the personalities of the majority, thus failing to match the “cultural norm.” Our studies examined how the interaction of individual- and cultural-level personality affects people’s self-esteem and well-being. We propose a person-culture match hypothesis that predicts that when a person’s personality matches the prevalent personalities of other people in a culture, culture functions as an important amplifier of the positive effect of personality on self-esteem and subjective well-being at the individual level. Across two studies, using data from more than 7,000 individuals from 28 societies, multilevel random-coefficient analyses showed that when a relation between a given personality trait and well-being or self-esteem exists at the individual level, the relation is stronger in cultures characterized by high levels of that personality dimension. Results were replicated across extraversion, promotion focus, and locomotive regulatory mode. Our research has practical implications for the well-being of both cultural natives and migrants.
