While the incentive sensitization theory of addiction acknowledges the important contributions of many former theories, it postulates that addiction is a state of aberrant motivation. Through repeated drug use, individuals with addiction become hypersensitive to the effects of the drugs themselves and to the stimuli associated with these drugs, including a variety of drug paraphernalia. For all individuals consuming drugs, drug-related stimuli have an inherent predictive value that signals an impending dose of the drug. For people with addiction, these drug cues move beyond being merely predictors for the drug and are imbued with excessive motivational value (called incentive salience); they become powerful motivational magnets capable of instigating and enhancing cravings for the drug. This incentive sensitization occurs through a process of neuroadaptations in the mesocorticolimbic dopamine system that have been shown to be long-lasting. These brain changes yield increasingly intense, highly focused cravings for an addictive target and transform cues related to the target into incentive stimuli that promote compulsive reward-seeking and relapse. The incentive sensitization theory does not deny a role for pleasure, habits, and withdrawal in addiction, but posits that those individuals with addiction (a) continue to take drugs compulsively even while experiencing diminished pleasure, (b) demonstrate creative new ways to procure drugs when necessary, and (c) often relapse well beyond when withdrawal has subsided. The critical factor in the development and maintenance of addiction is the persistent neuroadaptation that sensitizes the attribution of incentive salience to drugs and their cues, which explains why recovering from addiction is a long and slow process. The incentive sensitization theory can account for drug-induced attentional bias as well as how addiction can develop toward nondrug reward sources such as food, sex, and gambling environments.","PeriodicalId":339030,"journal":{"name":"Oxford Research Encyclopedia of Psychology","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126206091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, music performance usually involves motor tasks that are not learned spontaneously (as in the use of the vocal apparatus), the reproduction of preestablished sequences (notated or from memory), and synchronized joint performance with one or more other musicians. Music performance also relies on a rich repertoire of musical knowledge that can be used for purposes of expressive variation and improvisation. As such, the study of music performance provides a way to explore learning, motor control, memory, and interpersonal coordination in the context of a real-world behavior. Music performance skills vary considerably in the population and reflect interactions between genetic predispositions and the effect of intensive practice. At the same time, research suggests that most individuals have the capacity to perform music through singing or learning an instrument, and in this sense music performance taps into a universal human propensity for communication and coordination with conspecifics.","PeriodicalId":339030,"journal":{"name":"Oxford Research Encyclopedia of Psychology","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128680258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After the initial perception is resolved in favor of one of the interpretations, continued viewing leads to fluctuating subjective experience, as perception spontaneously switches between alternative states. Multistable perception occurs for different modalities, including visual, auditory, tactile, olfactory perception and proprioception, and various conflicting sensory representations, such as eye dominance, depth, motion, or meaning. Despite large differences, multistable stimuli produce quantitatively similar perceptual experience with stereotypical distribution of durations of dominance phases, similar dependence on the absolute and relative strength of competing perceptual interpretations, prior perceptual history, presentation method, attention, and volitional control, and so on. Taken together, this shows that multistable perception reflects the action of general canonical perceptual mechanisms whose purpose is to resolve the conflicting evidence and ensure a single dominant perception that can be used for action. Thus, it informs us about mechanisms of perceptual decision making, including the importance of feedback mechanisms in resolving perceptual ambiguity and the role of parietal and frontal regions in facilitating changes in perception. Multistable perception provides useful constraints for models, inspiring a plethora of models of perception that combine neurally plausible mechanisms, such as neural adaptation and inhibition, or are based on the idea of predictive coding. The sensitive nature of multistable perception makes a valuable experimental tool that can reveal even minor differences due to low- or high-level influences, including genetic or clinical cases. As such, it is an important tool in studying neural and behavioral correlates of consciousness as it dissociates perception from the stimulus.","PeriodicalId":339030,"journal":{"name":"Oxford Research Encyclopedia of Psychology","volume":"200 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115015676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Social cognitive inferences are typically varieties of diagnostic reasoning or, more properly, “abductive” reasoning, in which people infer simple but plausible—although not deductively certain—underlying causes for observable social behaviors. Abductive inference and its relationship to inductive and deductive inference are first introduced. A description of how abductive inference operates on a continuum between those that arise rapidly and automatically (and appear like deductions) and those that inspire more deliberative efforts (and thus often recruit more inductive information gathering and testing) is then given. Next, many classic findings in social cognition, and social psychology more broadly, that reveal how widespread this type of inference is explored. Indeed, both judgements under uncertainty and dual-process theories can be illuminated by incorporating the abductive frame. What then follows is a discussion on the work in ecological and evolutionary approaches that suggest that, although these inferences often go beyond the information given and are prone to predictable errors, people are good enough at social inference to qualify as being “ecologically rational.” The conclusion explores emerging themes in social cognition that only heighten the need for this broader understanding of inference processes.","PeriodicalId":339030,"journal":{"name":"Oxford Research Encyclopedia of Psychology","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125358154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The basic difference between telework and remote work is that a teleworker uses personal electronic devices in addition to working physically remotely from a place other than an office or company premises, whereas remote work does not require visits to the main workplace or the use of electronic personal devices. “Mobile tele- and remote workers” use several other places in addition to home for working. “Digital online telework” is a global form of employment that uses online platforms to enable individuals, teams, and organizations to access other individuals or organizations to solve problems or to provide services in exchange for payment. Often tele- and remote workers cowork in virtual teams and projects. The prevalence of various types of tele- and remote working vary. Although there are conceptual challenges to operationalizing the concept, it is estimated that hundreds of millions—and possibly more—people today earn their living working at and from their home or other places using digital tools and platforms. In the future, it is expected that new hybrid modes of working will emerge enabled by digital technologies. These changes in working increase the complexity of job demands because of the increased variety of contextual job characteristics. The main benefits of these new ways of working are organizational flexibility and individual autonomy; at the same time, unclear social relations may increase feelings of isolation and challenge the work-life balance.","PeriodicalId":339030,"journal":{"name":"Oxford Research Encyclopedia of Psychology","volume":"22 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128640222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet in many of them—including in organizational, political, and educational domains—leadership roles are disproportionately occupied by individuals of certain social categories (e.g., men, white individuals). Speaking to this imbalance in representation, there is a wealth of theory and research indicating that gender and race are key to understanding: (a) who tends to get placed in leadership roles, and (b) what an individual’s experience will be like while in that role or on the path to it. In part, this is because there are commonly held stereotypes that make certain individuals—often those of socially dominant racial and gender groups—seem better suited for leadership. By comparison, individuals of other genders and races are often perceived and evaluated as less suitable and treated as such (e.g., deprived of opportunities to become leaders or develop leadership skills). These stereotypes can also elicit disparate internal states (e.g., stereotype threat, internalized negative self-perceptions) that affect individuals’ likelihood of pursuing or obtaining such roles (e.g., by affecting their motivation or performance). In this way, leadership dynamics are intimately connected to the study of gender and race. Overall, these dynamics involve several psychological processes. This includes myriad forms of gender and racial bias—discrimination in evaluations, pay, hiring, promotions, and in access to role models, mentorship, and support; backlash effects, queen bee effects (self-group distancing), glass cliff effects, motherhood penalties, and fatherhood bonuses. It also involves multiple lines of theorizing—role congruity theory, lack of fit, masculine defaults and ambient belonging, modern sexism, aversive racism, social identity threat, and others.\u0000 Looking ahead, there are several critical directions for advancing research on gender, race, and leadership. This includes examining leadership processes from a more precise, intersectional lens rather than studying the implications of one’s gender or race in isolation (e.g., by integrating work on intersectionality theory, gendered races, and intersectional invisibility). Future study of these processes will also need to consider other relevant social identities (e.g., reflecting class, religion, age, sexuality, ability and neurodiversity, nationality, and immigration status), along with a more thorough consideration of gender—going beyond the study of (cisgender) men and women to consider how transgender and gender-nonconforming individuals are perceived and treated in leadership roles or on the path to such roles. Additionally, and ultimately, it will be critical to develop effective strategies for addressing the underrepresentation of women, racial and ethnic minorities, and other social groups in leadership. In part this will mean carefully evaluating strategies now being employed (e.g., organizational diversity messages, quotas and affirmative action, me","PeriodicalId":339030,"journal":{"name":"Oxford Research Encyclopedia of Psychology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125862180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Voices convey many kinds of information, including physical characteristics like body size and sex, as well as providing cues to the vocalizing individual’s identity and emotional state. Vocalizations are produced by dynamic modifications of the physiological vocal production system. The source-filter theory explains how vocalizations are produced in two stages: (a) the production of a sound source in the larynx, and (b) the filtering of that sound by the vocal tract. This two-stage process largely applies to all primate vocalizations. However, there are some differences between the vocal production apparatus of humans as compared to nonhuman primates, such as the lower position of the larynx and lack of air sacs in humans. Thanks to our flexible vocal apparatus, humans can produce a range of different types of vocalizations, including spoken language, nonverbal vocalizations, whispering, and singing.\u0000 A comprehensive understanding of vocal communication takes both production and perception of vocalizations into account. Internal processes are expressed in the form of specific acoustic patterns in the producer’s voice. In order to communicate information in vocalizations, those acoustic patterns must be acoustically registered by listeners via auditory perception mechanisms. Both production and perception of vocalizations are affected by psychobiological mechanisms as well as sociocultural factors. Furthermore, vocal production and perception can be impaired by a range of different disorders. Vocal production and hearing disorders, as well as mental disorders including autism spectrum disorder, depression, and schizophrenia, affect vocal communication.","PeriodicalId":339030,"journal":{"name":"Oxford Research Encyclopedia of Psychology","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127854047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These intra-individual factors are coordinated with what opportunities the situation affords and the perceived constraints placed on the person by their context and the norms of the culture they are in. Further, the intentions, attitudes, goals, beliefs, and desires of a person are often not known to them in any given moment, and because they reside within the mind of that person they are almost always not known to the people who are perceiving that person. To know anything about other people we must observe and identify/classify their behavior and then attribute to the observed behavior inferences and judgments about the internal states of that person serving as the motivating force behind their behavior. This entry explores this process of attribution. Heider described attribution as the process that determines “how one person thinks and feels about another person, how he perceives him and what he does to him, what he expects him to do or think, how he reacts to the actions of the other.” The entry explores the rules that people follow in order to make sense of behavior, and the rational versus non-rational nature of the procedure. Even when highly motivated to think rationally, this process can be biased, and flaws can appear in the attribution process, such as from chronic differences among perceivers due to culture, experience, or personality. How the process would unfold if accurate and purely rational is contrasted with how it unfolds when biased. How we feel, and how we choose to act, are derived from how we make sense of the world. Thus, attribution processes are foundational for understanding how we feel, for establishing expectations, and planning how to act in turn.","PeriodicalId":339030,"journal":{"name":"Oxford Research Encyclopedia of Psychology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128020765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
