Solving a problem requires relating the pieces of information available to each other and to the solution. We investigated how the strength of these relationships determines the likelihood of solving insight tasks based on remote associates. In these tasks, the solver is provided with several cues (e.g., drop , coat , summer ) and has to find the solution that matches those cues (e.g., rain ). We measured the semantic similarity between the cues and the solution ( cue–solution similarity ) as well as between cues ( cue–cue similarity ). We assume those relationships modulate two basic processes underlying insight problem-solving. First, there is an automatic activation process whereby conceptual activation spreads across a semantic network from each cue node to their associated nodes, potentially reaching the node of the solution. Thus, in general, the higher cue–solution similarity, the more likely the solution will be found (Prediction 1). Second, there is a controlled search process focused on an area in semantic space whose radius depends on competing cue–cue similarity. High cue–cue similarity will bias a search for the solution close to the provided cues because the associated nodes shared by both cues are highly coactivated. Therefore, high cue–cue similarity will have a beneficial effect when the cue–solution similarity is high but a detrimental effect when cue–solution similarity is low (Prediction 2). Our two predictions were confirmed using both verbal and pictorial remote association tasks, supporting the view that insight is dependent on an interaction of meaningful relationships between cues and solutions, and clarify the mechanisms of insight problem solving in remote associates.

Community-based question-and-answer (Q&A) websites have become increasingly popular in recent years as an alternative to general-purpose Web search engines for open-ended complex questions. Despite their unique contextual characteristics, only a handful of Q&A websites have been successful in sustaining members' active participation that, unlike lurking, consists of not only posting questions but also answering others' inquiries. Because the specific design of the information technology artifacts on Q&A websites can influence their level of success, studying leading Q&A communities such as Yahoo! Answers (YA) provides insights into more effective design mechanisms. We tested a goal-oriented action framework using data from 2,920 YA users, and found that active online participation is largely driven by artifacts (e.g., incentives), membership (e.g., levels of membership and tenure), and habit (e.g., past behavior). This study contributes to the information systems literature by showing that active participation can be understood as the setting, pursuit, and automatic activation of goals.

Literacy levels are highly variable within the deaf population and, compared to the general population, on average, reading levels are lower. As speech-based phonological coding is a known predictor of reading success in hearing individuals, much research has focussed on deaf readers’ processing of speech-based phonological codes during word recognition and reading as a possible explanation for the widespread reading difficulties in the deaf population. Although results are mixed, there is recent growing evidence that deaf and hearing readers process speech-based phonological codes differently. Furthermore, some studies indicate that phonological ability may not be a strong correlate of literacy skills in deaf, adult readers. Here, we investigate orthographic, semantic, and phonological processing during single word reading in deaf (N = 20) and hearing (N = 20) adult readers, who were matched on reading level. Specifically, we tracked deaf and hearing readers’ eye-movements using an adaptation of the visual world paradigm using written words and pictures. We found that deaf and hearing readers activate orthographic and semantic information following a similar time-course. However, there were differences in the way the groups processed phonology, with deaf readers making less use of phonological information. Crucially, as both groups were matched for reading level, reduced phonological processing did not appear to impact reading skill in deaf readers.

This study investigates the role of morphology during speech planning in Mandarin Chinese. In a long-lag priming experiment, thirty-two Mandarin Chinese native speakers were asked to name target pictures (e.g., “山” /shan1/ \"mountain\"). The design involved pictures referring to morpheme-related compound words (e.g., “山羊” /shan1yang2/ \"goat\") sharing a morpheme with the first (e.g., “山” /shan1/ \"mountain\") or the second position of the targets (e.g., 脑 /nao3/ “brain” with prime电脑 /dian4nao3/ “computer”), as well as unrelated control items. Behavioral and electrophysiological data were collected. Interestingly, the behavioral results went against earlier findings in Indo-European languages, showing that the target picture naming was not facilitated by morphologically related primes. This suggests no morphological priming for individual constituents in producing Mandarin Chinese disyllabic compound words. However, targets in the morpheme-related word condition did elicit a reduced N400 compared with targets in the morpheme-unrelated condition for the first position overlap in the ERP analyses but not for the second, suggesting automatic activation of the first individual constituent in noun compound production. Implications of these findings are discussed.

Background According to major cognitive accounts of panic disorder, bodily sensations can lead to automatic activation of an associative fear network, potentially triggering a cascade of cognitive, emotional, and physiological responses culminating in a panic attack. However, the evidence for the automatic associations assumed by these models is mixed. This may reflect the heterogeneous nature of panic disorder, in that the relative importance of different bodily sensations and symptoms varies between individuals. The current study aimed to test this possibility via measuring the associations between three different sets of panic symptoms (cognitive, respiratory, cardiac) and scores on three symptom-specific single target implicit association tests (STIATs). Methods A total of 226 unselected female participants aged 18–35 completed the STIATs as well as questionnaires assessing panic symptoms and related measures in a web-based study. Results Only limited evidence was found to support the idea of specific associations between STIAT stimuli sets and their related panic symptoms. Exploratory analyses indicated that there were only associations between STIAT scores and panic-relevant questionnaires amongst those participants who had experienced a panic attack in the previous 6 months. Conclusions The results have implications for measuring panic-relevant associations and understanding their role in panic disorder.

A novel, person centered approach to the understanding and treatment of severe mental illness—Recovery Oriented Cognitive Therapy (CT-R)—has recently been implemented in many settings in the mental health care system. The theory and therapy, originally based on clinical observations, are grounded on the assumption that the personality is composed of a number of “modes” which are composed of specific components such as cognition, affect, motivation and behavior. The activation of a particular mode and its status as relatively adaptive or maladaptive depends on the “fit” between an individual’s internal impulses and cravings and external situational factors. In addition, persistent cognitive distortions within the modes may be responsible for poor adaptation observed in psychiatric disorders. We outline here the difference between the reflexive, automatic activation of modes and a separate superordinate function that provides oversight for the modes. We focus on the theory of modes as it applies to schizophrenia, as individuals given this diagnosis are “stuck” in maladaptive modes. Additionally, we outline some core therapeutic elements of CT-R, which aim to activate the adaptive modes of personality, deactivate the maladaptive modes, and promote movement towards recovery. Finally, we project our understanding of modes onto other psychopathological and non-clinical populations and propose suggestions for the application of this theory in future research and practice.

Reading involves activation of phonological and semantic knowledge. Yet, the automaticity of the activation of these representations remains subject to debate. The present study addressed this issue by examining how different brain areas involved in language processing responded to a manipulation of bottom-up (level of visibility) and top-down information (task demands) applied to written words. The analyses showed that the same brain areas were activated in response to written words whether the task was symbol detection, rime detection, or semantic judgment. This network included posterior, temporal and prefrontal regions, which clearly suggests the involvement of orthographic, semantic and phonological/articulatory processing in all tasks. However, we also found interactions between task and stimulus visibility, which reflected the fact that the strength of the neural responses to written words in several high-level language areas varied across tasks. Together, our findings suggest that the involvement of phonological and semantic processing in reading is supported by two complementary mechanisms. First, an automatic mechanism that results from a task-independent spread of activation throughout a network in which orthography is linked to phonology and semantics. Second, a mechanism that further fine-tunes the sensitivity of high-level language areas to the sensory input in a task-dependent manner. •Automatic access to phonological and semantic information during reading was examined.•We manipulated stimulus’ level of visibility (bottom-up) and task demand (top-down).•Brain areas influenced by bottom-up and/or top-down information were identified.•Both stimulus-driven and task-dependent mechanisms played a role during the process.•Yet, their relative contribution depends on the functional role of each ROI.

The current study examined automatic activation and semantic influences from the non-target language of different-script bilinguals during visual word processing. Thirty-four Arabic–Hebrew bilinguals and 34 native Hebrew controls performed a semantic relatedness task on visually presented Hebrew word pairs. In one type of critical trials, cognate primes between Arabic and Hebrew preceded related Hebrew target words. In a second type, false-cognate primes preceded Hebrew targets related to the Arabic meaning (but not the Hebrew meaning) of the false-cognate. Although Hebrew orthography is a fully reliable cue of language membership, facilitation on cognate trials and interference on false-cognate trials were observed for Arabic–Hebrew bilinguals. The activation of the non-target language was sufficient to influence participants’ semantic decisions in the target language, demonstrating simultaneous activation of both languages even for different-script bilinguals in a single language context. To discuss the findings we refine existing models of bilingual processing to accommodate different-script bilinguals.

Biodegradable batteries play an important role in fully degradable biomedical or environmental systems. The development of biodegradable batteries faces many challenges including power content, device compactness, performance stability, shelf and functional lifetime. In particular, a key driver in the lifetime and overall size of microfabricated biodegradable batteries is the liquid electrolyte volume. Harnessing liquid from the environment to serve as the battery electrolyte may, therefore, be desirable; however, for stable operation, maintaining a constant electrochemical environment inside the cell is required even in the presence of changing body or environmental conditions. We report a biodegradable battery featuring a solid electrolyte of sodium chloride and polycaprolactone. This approach harnesses the body fluid that diffuses into the cell as an element of the electrolyte; however, the large excess of sodium chloride suspended in the polycaprolactone holds intracell ionic conditions constant. A constant discharge profile can then be achieved even in the presence of varying external aqueous conditions, enabling compact, stable-performing cells. This design also features easy integration and automatic activation, providing a simplified strategy to fabricate batteries with long shelf life and desirable functional life span. In addition, the polymeric skeleton of the solid electrolyte system acts as an insulating layer between electrodes, preventing the metallic structure from short-circuit during discharge.

We investigated the neurophysiological mechanisms underlying bi-alphabetic reading using event-related potentials (ERPs). Brain activity was recorded using EEG in a group of Russian–English biliterates during a reading-aloud task with familiar and novel words. Capitalizing on a partial overlap between the Roman and Cyrillic alphabets, the stimuli were presented in L1 Cyrillic, L2 Roman, or in an ambiguous script, in a counterbalanced fashion. The results revealed functional dissociation between the stimuli in terms of processing their graphemic ambiguity. The interference caused by L1-L2 script inconsistencies in novel wordforms was detected at a late processing stage, reflected in N400 response enhancement for unfamiliar script-ambiguous items. Conversely, familiar ambiguous and L2 words showed no N400 increase but demonstrated an early enhancement of the P200 component in comparison to those presented in L1. These results indicate the use of a whole-word reading strategy for familiar words even in ambiguous script, likely triggered by an automatic activation of well-established lexico-semantic representations. The absence of similar top-down mechanisms for novel ambiguous-script words likely results in increased grapheme-to-phoneme decoding effort, with important implications for L2 reading and vocabulary acquisition.
