Blind Speakers Show Language‐Specific Patterns in Co‐Speech Gesture but Not Silent Gesture

Sighted speakers of different languages vary systematically in how they package and order components of a motion event in speech. These differences influence how semantic elements are organized in gesture, but only when those gestures are produced with speech (co‐speech gesture), not without speech (silent gesture). We ask whether the cross‐linguistic similarity in silent gesture is driven by the visuospatial structure of the event. We compared 40 congenitally blind adult native speakers of English or Turkish (20/language) to 80 sighted adult speakers (40/language; half with, half without blindfolds) as they described three‐dimensional motion scenes. We found an effect of language on co‐speech gesture, not on silent gesture—blind speakers of both languages organized their silent gestures as sighted speakers do. Humans may have a natural semantic organization that they impose on events when conveying them in gesture without language—an organization that relies on neither visuospatial cues nor language structure.     

Look who's talking? Sound changes gaze behaviour in a dynamic social scene

Humans often look at other people in natural scenes, and previous research has shown that these looks follow the conversation and that they are sensitive to sound in audiovisual speech perception. In the present experiment, participants viewed video clips of four people involved in a discussion. By removing the sound, we asked whether auditory information would affect when speakers were fixated, how fixations between different observers were synchronized, and whether the eyes or mouth were looked at most often. The results showed that sound changed the timing of looks—by alerting observers to changes in conversation and attracting attention to the speaker. Clips with sound also led to greater attentional synchrony, with more observers fixating the same regions at the same time. However, looks towards the eyes of the people continued to dominate and were unaffected by removing the sound. These findings provide a rich example of multimodal social attention.     

Contextual Integration in Multiparty Audience Design

Communicating with multiple addressees poses a problem for speakers: Each addressee necessarily comes to the conversation with a different perspective—different knowledge, different beliefs, and a distinct physical context. Despite the ubiquity of multiparty conversation in everyday life, little is known about the processes by which speakers design language in multiparty conversation. While prior evidence demonstrates that speakers design utterances to accommodate addressee knowledge in multiparty conversation, it is unknown if and how speakers encode and combine different types of perspective information. Here we test whether speakers encode the perspective of multiple addressees, and then simultaneously consider their knowledge and physical context during referential design in a three‐party conversation. Analyses of referential form—expression length, disfluency, and elaboration rate—in an interactive multiparty conversation demonstrate that speakers do take into consideration both addressee knowledge and physical context when designing utterances, consistent with a knowledge‐scene integration view. These findings point to an audience design process that takes as input multiple types of representations about the perspectives of multiple addressees, and that bases the informational content of the to‐be‐designed utterance on a combination of the perspectives of the intended addressees.     

Trash talk in a competitive setting: Impact on self‐efficacy and affect

The effects of trash talk and competition outcome on self‐efficacy and affect were examined in 40 Madden? NFL 08 football video game players randomly assigned to two conditions: silence talk, where they played the first game in complete silence; and the second trash talking. Measures of self‐efficacy, positive affect (PA), and negative affect (NA) were administered. Results revealed that players enforced to be silent in the first game instantaneously exhibited lower self‐efficacy, lower PA, and higher NA than players permitted to talk in Game 1. However, players subsequently instructed to remain silent in the second game showed markedly decreased self‐efficacy compared to players permitted to talk in Game 2. Results are interpreted in light of the social‐cognitive‐motivational theory.     

“I don't know but I know who to ask”: 12‐month‐olds actively seek information from knowledgeable adults

Active social communication is an effective way for infants to learn about the world. Do pre‐verbal and pre‐pointing infants seek epistemic information from their social partners when motivated to obtain information they cannot discover independently? The present study investigated whether 12‐month‐olds (N = 30) selectively seek information from knowledgeable adults in situations of referential uncertainty. In a live experiment, infants were introduced to two unfamiliar adults, an Informant (reliably labeling objects) and a Non‐Informant (equally socially engaging, but ignorant about object labels). At test, infants were asked to make an impossible choice—locate a novel referent among two novel objects. When facing epistemic uncertainty—but not at other phases of the procedure—infants selectively referred to the Informant rather than the Non‐Informant. These results show that pre‐verbal infants use social referencing to actively and selectively seek information from social partners as part of their interrogative communicative toolkit.

The Illusion of Double‐Discount: Using Reference Points in Promotion Framing

Double‐discount is an effective format for promoting purchase decisions. However, extant literature has overlooked how temporal order of discounts applied affects consumers’ purchase decisions. In this paper, we show that the sequence of discount magnitude (e.g., 10% followed by 40% vs. 40% followed by 10%) leads to biases in consumer judgment and influences the perceived appeal and purchase intention of the deal. We term this the double‐discount sequence effect. Using four experiments, we showed that double‐discount in an ascending sequence (e.g., taking 10% off, then an additional 40% off) is preferable over that in a descending sequence. We also found that discount application sequence—but not the presentation order—matters to consumers. Consumers anchor on the first discount they encounter and evaluate the second discount with respect to this first one.     

Stigmatized‐Identity Cues: Threats as Opportunities for Consumer Psychology

In their review of the literature on stigmatized‐identity cues, Chaney, Sanchez, and Maimon (2019—this issue) summarize evidence that stigmatized‐identity threat and safety cues drive consumer behavior through their effects on consumers’ inferences about the company's ideology and their consequential impact on feelings of belonging. The authors also identify various factors that moderate the relationship between these identity cues and consumers’ belonging perceptions. In our commentary, we identify future research opportunities by: (a) encouraging efforts to broaden the proposed framework to account for stigmatized identities defined in terms of consumption activities, (b) highlighting concepts and relationships that may require re‐examination or deeper understanding, and (c) proposing additional consumer behaviors that punish or reward companies that use stigmatized‐identity threat and safety cues, respectively.     

Observers' Language Proficiencies and the Detection of Non‐native Speakers' Deception

We examined whether observers' language proficiencies affected their abilities to detect native and non‐native speakers' deception. Native and non‐native English speakers were videotaped as they either lied or told the truth about having cheated on a test. A total of 284 laypersons—who were either native or non‐native English speakers themselves—viewed these videos and indicated whether they believed that the speakers were being truthful or deceptive. Observers were more accurate when judging native speakers than when judging non‐native speakers, suggesting that perceptual fluency aided deception detection. Although there was no effect of observers' language proficiencies on discrimination, their belief that interviewees were telling the truth increased with proficiency. On the whole, these findings suggest that non‐native speakers may be at greater risk of being incorrectly classified in forensic contexts.Copyright © 2017 John Wiley & Sons, Ltd.     

Testing the Cross-Cultural Generality of Hering's Theory of Color Appearance

This study examines the cross-cultural generality of Hering's (1878/1964) color-opponent theory of color appearance. English-speaking and Somali-speaking observers performed variants of two paradigms classically used to study color-opponency. First, both groups identified similar red, green, blue, and yellow unique hues. Second, 25 English-speaking and 34 Somali-speaking observers decomposed the colors present in 135 Munsell color samples into their component Hering elemental sensations—red,green,blue, yellow, white, and black—or else responded “no term.” Both groups responded no term for many samples, notably purples. Somali terms for yellow were often used to name colors all around the color circle, including colors that are bluish according to Hering's theory. Four Somali Grue speakers named both green and blue elicitation samples by their term for green. However, that term did not name the union of all samples called blue or green by English speakers. A similar pattern was found among three Somali Achromatic speakers, who called the blue elicitation sample black or white. Thus, color decomposition by these Somali-speaking observers suggests a lexically influenced re-dimensionalization of color appearance space, rather than a simple reduction of the one proposed by Hering. Even some Somali Green-Blue speakers, whose data were otherwise similar to English, showed similar trends in yellow and blue usage. World Color Survey data mirror these results. These within- and cross-cultural violations of Hering's theory do not challenge the long-standing view that universal sensory processes mediate color appearance. However, they do demonstrate an important contribution of language in the human understanding of color.     

Speech Planning at Turn Transitions in Dialog Is Associated With Increased Processing Load

Speech planning is a sophisticated process. In dialog, it regularly starts in overlap with an incoming turn by a conversation partner. We show that planning spoken responses in overlap with incoming turns is associated with higher processing load than planning in silence. In a dialogic experiment, participants took turns with a confederate describing lists of objects. The confederate’s utterances (to which participants responded) were pre‐recorded and varied in whether they ended in a verb or an object noun and whether this ending was predictable or not. We found that response planning in overlap with sentence‐final verbs evokes larger task‐evoked pupillary responses, while end predictability had no effect. This finding indicates that planning in overlap leads to higher processing load for next speakers in dialog and that next speakers do not proactively modulate the time course of their response planning based on their predictions of turn endings. The turn‐taking system exerts pressure on the language processing system by pushing speakers to plan in overlap despite the ensuing increase in processing load.     

Exploiting the Wisdom of Others to Make Better Decisions: Suspending Judgment Reduces Egocentrism and Increases Accuracy

Although decision makers often consult other people's opinions to improve their decisions, they fail to do so optimally. One main obstacle to incorporating others' opinions efficiently is one's own opinion. We theorize that decision makers could improve their performance by suspending their own judgment. In three studies, participants used others' opinions to estimate uncertain quantities (the caloric value of foods). In the full‐view condition, participants could form independent estimates prior to receiving others' opinions, whereas participants in the blindfold condition could not form prior opinions. We obtained an intriguing blindfold effect. In all studies, the blindfolded participants provided more accurate estimates than did the full‐view participants. Several policy‐capturing measures indicated that the advantage of the blindfolded participants was due to their unbiased weighting of others' opinions. The full‐view participants, in contrast, adhered to their prior opinion and thus failed to exploit the information contained in others' opinions. Moreover, in all three studies, the blindfolded participants were not cognizant of their advantage and expressed less confidence in their estimates than did the full‐view participants. The results are discussed in relation to theories of opinion revision and group decision making. Copyright © 2011 John Wiley & Sons, Ltd.     

A Self‐Categorization Explanation for Opinion Consensus Perceptions

The public expression of opinions (and related communicative activities) hinges upon the perception of opinion consensus. Current explanations for opinion consensus perceptions typically focus on egocentric and other biases, rather than functional cognitions. Using self‐categorization theory we showed that opinion consensus perceptions flow from cognitions regarding the fit between issues and group prototypes. Strong normative fit enhanced perceptions of ingroup opinion consensus (Experiments 1 and 2), and consensus perceptions varied as a function of comparison outgroups (Experiment 3), ingroup prototype salience (Experiment 4), and levels of identity threat (Experiment 5). Self‐categorization theory has the potential to integrate a variety of cognitive and motivational processes to provide a comprehensive explanation for opinion consensus perceptions.     

Person‐centred counsellors' experiences of working with clients in crisis: A qualitative interview study

Aims: This study aims to explore and understand person‐centred therapists’ experiences and work with clients at the pivotal point of crisis. Specifically: how do person‐centred therapists experience working with clients in crisis? Do they identify differences in crisis intervention compared to non‐crisis work? What do they perceive as helpful to crisis clients? How relevant are therapists' own experiences of crisis? Method: Participants were all experienced person‐centred therapists. Qualitative, semi‐structured interviews were conducted and the data were analysed qualitatively using person‐centred/phenomenological methodology. Results: Respondents identified differences in their experiences. Typically, therapists described polarity in their experience of danger and opportunity, also heightened energy levels within themselves, perceived higher levels of engagement, faster pace of work, experiences of reaching ‘relational depth’ earlier, and the importance of assisting symbolisation of clients' experience in awareness. Clients were experienced as vulnerable, unable to access previous coping mechanisms, in a state of breakdown and disintegration, but also as wide open, having dropped their usual defences, and more available to engage in therapy and enter the process of change and potential post‐crisis growth. Discussion: The findings are discussed in relation to prevailing models of crisis intervention, person‐centred theory and theoretical developments in post‐traumatic growth in the aftermath of crisis.     

Ethicists’ and Nonethicists’ Responsiveness to Student E‐mails: Relationships Among Expressed Normative Attitude,Self‐Described Behavior,and Empirically Observed Behavior

Do professional ethicists behave any morally better than other professors do? Do they show any greater consistency between their normative attitudes and their behavior? In response to a survey question, a large majority of professors (83 percent of ethicists, 83 percent of nonethicist philosophers, and 85 percent of nonphilosophers) expressed the view that “not consistently responding to student e‐mails” is morally bad. A similarly large majority of professors claimed to respond to at least 95 percent of student e‐mails. These professors, and others, were sent three e‐mails designed to look like queries from students. Ethicists’ e‐mail response rates were not significantly different from the other two groups’. Expressed normative view correlated with self‐estimated rate of e‐mail responsiveness, especially among the ethicists. Empirically measured e‐mail responsiveness, however, was at best weakly correlated with self‐estimated e‐mail responsiveness; and professors’ expressed normative attitude was not significantly correlated with empirically measured e‐mail responsiveness for any of the three groups.     

Minority Opinions: Antecedents and Benefits of Expression

A great deal of social psychological research has focused on antecedents of conformity to the majority. The present article, however, reviews the various conditions under which people express minority opinions. First, minority opinion expression is especially pronounced among individuals who hold either strong attitudes or attitudes that deviate from the majority in a direction consistent with the desirable group attitude. Second, minority opinion expression increases to the extent that highly‐identified group members believe that expressing minority opinions will promote their group’s welfare, or to the extent that one’s membership in a particular social category entitles him/her to speak up. Third, minority opinion expression increases when people’s motives to have a unique or clearly defined sense of self are salient. It is argued that these sources of minority opinion expression can help shed light on the functional value of such opinions for individuals.     

Disrupting the flow: How brief silences in group conversations affect social needs

We all know the awkward feeling when a conversation is disrupted by a brief silence. This paper studies why such moments can be unsettling. We suggest that silences are particularly disturbing if they disrupt the conversational flow. In two experiments we examined the effects of a single brief instance of silence on social needs, perceived consensus, emotions, and rejection. Study 1 demonstrated that fluent conversations are associated with feelings of belonging, self-esteem, and social validation. If a brief silence disrupts this fluency, negative emotions and feelings of rejection arise. Study 2 replicated these effects in a more realistic setting, and showed that the effects of a brief silence are considerable despite participants' unawareness of the silence. Together, results show that conversational flow induces a sense of belonging and positive self-esteem. Moreover, this research suggests an implicit route to social validation, in which consensus is inferred from fluent group conversation.     

The statistical recommendations of the American Psychological Association Publication Manual: Effect sizes,confidence intervals,and meta‐analysis

Estimation based on effect sizes, confidence intervals, and meta‐analysis usually provides a more informative analysis of empirical results than does statistical significance testing, which has long been the conventional choice in psychology. The sixth edition of the American Psychological Association Publication Manual now recommends that psychologists should, wherever possible, use estimation and base their interpretation of research results on point and interval estimates. We outline the Manual's recommendations and suggest how they can be put into practice: adopt an estimation framework, starting with the formulation of research aims as ‘How much?’ or ‘To what extent?’ questions. Calculate from your data effect size estimates and confidence intervals to answer those questions, then interpret. Wherever appropriate, use meta‐analysis to integrate evidence over studies. The Manual's recommendations can assist psychologists improve they way they do their statistics and help build a more quantitative and cumulative discipline.     

Referential Form and Memory for the Discourse History

The way we refer to things in the world is shaped by the immediate physical context as well as the discourse history. But what part of the discourse history is relevant to language use in the present? In four experiments, we combine the study of task-based conversation with measures of recognition memory to examine the role of physical contextual cues that shape what speakers perceive to be a part of the relevant discourse history. Our studies leverage the differentiation effect, a phenomenon in which speakers are more likely to use a modified expression to refer to an object (e.g., dotted sock) if they had previously described a similar object (e.g., striped sock) than when they had not described a similar object. Two physical cues—the background that framed the to-be-described pictures and the position of the pictures in the display—were manipulated to alter perceptions about the relevant discourse context. We measured the rate with which speakers modify referring expressions to differentiate current from past referents. Recognition memory measures following the conversation probed what was and was not remembered about past discourse referents and contexts. Analysis of modification rates indicated that these contextual grouping cues shaped perceptions about the relevant discourse context. The contextual cues did not affect memory for the referents, but the memory for past referents was better for speakers than for listeners. Our findings show that perceptions about the relevant discourse history are a key determinant of how language is used in the moment but also that conversational partners form asymmetric representations of the discourse history.     

Neurones miroir, résonance et cognition sociale

Mirror neurons were discovered in the 1990's by cognitive neuroscientists from Parma. How central are mirror neurons in primates, social cognition. Do mirror neurons enable an observer to match the agent's observed movements onto her own motor repertoire? Does this matching enable the observer to represent the agent's intention, as argued by Rizzolatti et al? A positive answer to these questions can't be provided unless one assumme that mirror neurons compute the goal of an action by means of a “forward model” of the perceived action. However, the experimental evidence rather suggests that mirror neurons compute the motor means for achieving the desired goal, in accordance with an “inverse model” of the perceived action.     

Action‐oriented Perception

Abstract: When I throw a ball at you, do you see it as catch‐able? Do we perceive objects as edible, climbable or Q‐able in general? One could argue that it is just a manner of speaking to say so: we do not really see an object as edible, we only infer on the basis of its other properties that it is. I argue that whether or not an object is edible or climbable is indeed represented perceptually: we see objects as edible, and do not just believe that they are. My argument proceeds in two steps. First, I argue that in order to perform an action Q with respect to an object, we need to represent this object as Q‐able and, second, I argue that we represent objects as having these properties perceptually.
