Hemispheric asymmetries for global and local processing as a function of stimulus exposure duration

The experiments assess the relationship between stimulus exposure duration and hemispheric asymmetries for global and local processing. Six durations (27, 40, 53, 67, 80, and 147 ms) were tested in a selective attention task in which hierarchical letterforms were presented unilaterally to the left or right visual field. The results indicated that left hemisphere-local asymmetries were demonstrated more often than right hemisphere-global asymmetries and that asymmetries were most commonly found in the middle range of durations tested. The pattern of results emphasizes the importance of further study into those conditions under which the predicted asymmetries can be reliably demonstrated in healthy individuals.     

Managing the interactions between multiple identities in inter-organizational collaborations: an identity work perspective

Inter-organizational collaboration (IOC) research considers the achievement of a collaborative identity as a key enabler of a successful collaboration. As a result, little has been said about the interactions between collaborative and non-collaborative identities. We build on narrative identity work and positioning theory, to explore how collaboration partners engage in identity work positioning to manage the interactions of the multiple identities emerging through the process of collaboration as they try to accomplish collaborative work. We illustrate this process through a qualitative longitudinal study of an educational partnership in Greece. Our analysis shows how IOC partners manage the interactions between collaborative and non-collaborative identities by positioning themselves, and others, in narratives of collaboration as part of their daily identity work when responding to emerging collaborative needs. Our research extends our current understanding of identity work processes in IOCs by demonstrating the paradoxical nature of the collaboration, which requires relying on both collaborative and non-collaborative identities for the successful achievement of aims. We therefore suggest that identity tensions should not be resolved but rather managed, since they enable partners to respond creatively to contextual organizational changes and make sense of the collaboration as it happens.     

Culture variation in the average identity extraction: The role of global vs. local processing orientation

ABSTRACT

Research has shown that observers often spontaneously extract a mean representation from multiple faces/objects in a scene even when this is not required by the task. This phenomenon, now known as ensemble coding, has so far mainly been based on data from Western populations. This study compared East Asian and Western participants in an implicit ensemble-coding task, where the explicit task was to judge whether a test face was present in a briefly exposed set of faces. Although both groups showed a tendency to mistake an average of the presented faces as target, thus confirming the universality of ensemble coding, East Asian participants displayed a higher averaging tendency relative to the Westerners. To further examine how a cultural default can be adapted to global or local processing demand, our second experiment tested the effects of priming global or local processing orientation on ensemble coding via a Navon task procedure. Results revealed a reduced tendency for ensemble coding following the priming of local processing orientation. Together, these results suggest that culture can influence the proneness to ensemble coding, and the default cultural mode is malleable to a temporary processing demand.     

Comparative identity and evaluation of socio-political change: Perceptions of the European Community as a function of the salience of regional identities

Using questionnaire data concerning perceptions of the European Community (EC) in Scotland and Andalucia we explored how the EC is perceived, and a European identification adopted as a function of the salience of these ‘regional’ identities. Drawing on the work concerning the concept of ‘comparative identity’ (Ros, Cano & Huici, 1987) it is argued that disidentification with the ‘nation-state’ (i.e. Britain and Spain respectively) is a useful way of measuring the salience of such regional identities in the self/concept. We predicted that such identities would be more salient in Scotland than in Andalucia and that in Scotland the salience of subjects' regional identities would be associated with beliefs concerning the need for strategies of regional empowerment in its relation to the nation (Britain). We further predicted that the EC would be judged as a function of this comparative identity so that in Scotland (but not in Andalucia), a European identification would be associated with what may be called ‘social change’ beliefs (e.g. beliefs concerning the need for changing aspects of the region's relationship with the nation). Supportive evidence is found for all these predictions. However, no support was found for our prediction of a correlation between the Scots' regional identification and their European identification. The paper concludes with a discussion of the utility of the concept of comparative identity. © 1997 by John Wiley & Sons, Ltd.     

Being bicultural: a mixed-methods study of adolescents' implicitly and explicitly measured multiethnic identities

Understanding how ethnic identities develop in adolescence is currently limited by a reliance on self-report paper-and-pencil measures. This mixed-methods study presents a novel response time measure, the Multiethnic Identities Processing Task (MIPT), to quantify bicultural adolescents' implicit identifications with ethnic and racial identity labels. Eighty-four adolescents (age 14-21 years) of diverse ethnic and racial backgrounds self-identified as bicultural or not bicultural and described their ethnic identities, pride, and ethnic centrality during a brief interview. Participants were assigned to complete either the interview (self-prime) or the MIPT (no prime) first. Results indicate that bicultural adolescents readily endorsed a variety of ethnic and racial labels in the MIPT, reflecting their multifaceted identities. Younger bicultural adolescents showed a large inhibited response to the label "White," indicating some hesitation in deciding whether the label was "like me" or "not like me." Heart rate monitoring and qualitative analyses of interviews provide some insight into this pattern of results. Findings are discussed with respect to developmental theory, and the strengths of using both implicit and explicit measures to understand multiethnic identity development in adolescence.     

Integration of local features as a function of global goodness and spacing

In two experiments, the accuracy with which subjects detected a conjunction of features was examined as a function of the spacing between items and the goodness of the axis along which they were located. In each array, two items were arranged along a vertical, a horizontal, or a diagonal axis. Based on the well-established oblique effect, the vertical and horizontal axes were considered to be good global patterns and the diagonals were considered to be poor. In Experiment 1, the two items in an array could be two horizontal lines, two vertical lines, a vertical and a horizontal line, or a plus sign with one of the single lines. In Experiment 2, a positive- and a negative-diagonal line were used as the individual features, and an "X" was used as the conjunction. The results from Experiment 1 indicated that global goodness influenced only the rate of illusory conjunctions, and not of feature errors. Illusory conjunctions of vertical and horizontal line segments were more likely to occur in vertical and horizontal arrangements. The results from Experiment 2 revealed a reversal of the effect of global goodness on the rate of illusory conjunctions: Illusory conjunctions of negative- and positive-diagonal line segments were more likely to occur in diagonal arrangements. The results of both experiments taken together showed the existence of an important and new factor that influences the likelihood that features of shape will be conjoined: the ease with which line segments conjoin when they are translated along their extent toward each other. In both experiments, greater spacing between items produced more feature-identification errors and fewer feature-integration errors than did less spacing.     

Longitudinal trajectories of bicultural identity integration in recently immigrated Hispanic adolescents: Links with mental health and family functioning

This study examined, in a sample of recently immigrated Hispanic adolescents in Miami and Los Angeles, the extent to which bicultural identity integration (BII; involving the ability to synthesise one's heritage and receiving cultural streams and to identify as a member of both cultures) is best understood as a developmental construct that changes over time or as an individual‐difference construct that is largely stable over time. We were also interested in the extent to which these trajectories predicted mental health and family functioning. Recent‐immigrant 9th graders (N = 302) were assessed 6 times from 9th to 12th grade. Latent class growth analyses using the first 5 timepoints identified 2 trajectory classes—one with lower BII scores over time and another with higher BII scores over time. Higher heritage and US identity at baseline predicted membership in the higher BII class. At the 6th study timepoint, lower BII adolescents reported significantly poorer self‐esteem, optimism, prosocial behaviour and family relationships compared with their higher BII counterparts. These findings are discussed in terms of further research on the over‐time trajectory of biculturalism, and on the need to develop interventions to promote BII as a way of facilitating well‐being and positive family functioning.     

The integration of object levels and their content: a theory of global/local processing and related hemispheric differences

This article presents and tests the authors' integration hypothesis of global/local processing, which proposes that at early stages of processing, the identities of global and local units of a hierarchical stimulus are represented separately from information about their respective levels and that, therefore, identity and level information have to be integrated at later stages. It further states that the cerebral hemispheres differ in their capacities for these binding processes. Three experiments are reported in which the integration hypothesis was tested. Participants had to identify a letter at a prespecified level with the viewing duration restricted by a mask. False reporting of the letter at the nontarget level was predicted to occur more often when the integration of identity and level could fail. This was the case. Moreover, visual-field effects occurred, as expected. Finally, a multinomial model was constructed and fitted to the data.     

Hemispheric differences for global/local processing in divided attention tasks: further evidence for the integration theory

Functional hemispheric asymmetries with respect to global/local processing have been observed more reliably in divided-attention than in selective-attention tasks. This difference has been accounted for by assuming that the hemispheres operate differently in the two tasks. In our study, the alternative hypothesis was tested that the interference between the global and local levels is increased under divided attention, and that this makes it necessary to base response selection on a more elaborated mental stimulus representation in which the levels and their content are integrated. Because the hemispheres systematically differ in this integration process, the increased interference between the levels explains why the corresponding asymmetries occur more reliably under divided attention. Two experiments supporting this hypothesis are reported, one with a divided and one with a selective attention task.     

Subliminal primes for global or local processing influence judgments of vehicular traffic

Previous studies on semantic priming show that briefly presented words can unconsciously manipulate subjects’ mental states, behaviors, and attitudes. Here we evaluated whether semantic primes can also manipulate the breadth of subjects’ visual attention. We primed participants with briefly presented words that indicate either broadness or narrowness; each prime was followed by either a large or a small picture of a street intersection with vehicles, and participants had to indicate in which order the vehicles were legally allowed to pass the intersection. Participants responded to large pictures faster when primed with words denoting broadness, and to small pictures faster when primed with words denoting narrowness. From this we concluded that semantic priming can be effectively applied to manipulate the breadth of attention, which could be exploited in real-world scenarios.     

East of West,West of East: a matter of global and local identity

Research is a very personal matter. On the basis of experiences in different countries with researchers from different cultures over many years, some observations will be described. The conceptual frame of this attempt is to look for anthropological universals and cultural specifics. Much can be learned from spatial representations in the arts. Whereas in the West since Renaissance time the central perspective has become dominant in visual art, in Eastern landscape paintings the “floating view” is typical. The claim that the central perspective corresponds to geometric laws and matches how we see the world is misleading for at least two reasons: It violates mechanisms of size constancy, and the visual world is spatially reduced in pictures to the perifoveal region only. Research on spatial attention has disclosed two different attentional systems being responsible either for near-fovea vision or for the far periphery. This fundamental principle as a global characteristic of visual processing is neglected in Western art. In Eastern art with a floating view geometric laws are violated, and different potential perspectives are integrated within a holistic pattern. The semantics of what shall be expressed becomes important irrespective of physical parameters. The latter may also create the unique phenomenon of becoming subjectively part of the picture confirming personal identity. Cultural specifics like in the arts (what one might expect) can surprisingly also be observed in theoretical considerations about visual processing. Whereas in the tradition of Western science visual percepts are built up with local elements like feature detectors, in an important Chinese theory global topological features are analyzed first. An important task of the brain is to create the identity of a percept on the basis of spatially and temporally distributed neural activities. It is, thus, an important theoretical question how to deal with the challenge to create and maintain the identity of a percept for some time. It is suggested that one should leave behind a monocausal reasoning for such explanations but adopt for analytical strategies the concept of complementarity as a generative principle.     

Social identities, group norms, and threat: on the malleability of ingroup bias

Ingroup bias is one of the most basic intergroup phenomena and has been consistently demonstrated to be increased under conditions of existential threat. In the present research the authors question the omnipresence of ingroup bias under threat and test the assumptions that these effects depend on the content of social identity and group norm salient in a situation. In the first two studies cross-categorization and recategorization manipulations eliminated and even reversed mortality salience effects on bias in relations between English and Scottish students (Study 1) as well as English and French people (Study 2). In the third study the specific normative content of a given social identity (collectivism vs. individualism) was shown to moderate mortality salience effects on ingroup bias. The results of these studies suggest a social identity perspective on terror management processes.     

Goals as identities: Boosting perceptions of healthy-eater identity for easier goal pursuit

People who think of their personal goals as identities are more likely to engage in goal-consistent behavior. However, no research has explored whether learning to frame goals as identities can be an effective strategy for pursuing goals in daily life. Across a series of studies, we assessed how incorporating a goal as part of one’s identity impacts goal-consistent choices. In a pilot study, we established a positive correlational relationship between natural goal identification and goal-consistent decision-making. Individuals with stronger healthy-eater identities made healthier food choices in a behavioral choice task. In Studies 1 and 2, we employed longitudinal interventions to teach people to frame their healthy eating goals as identities. We found that people who learned to frame their goals as identities made healthier choices, felt their goals were easier to pursue, reported greater success at managing goals, and made food choices that they both perceived to be healthier and that were rated as healthier by independent evaluators. Across studies, our findings suggest that thinking of goals as identities makes it easier to engage in goal-consistent choices.

     

When multiple identities interfere: the role of identity centrality

The current study extends research in the area of identity conflict or interference by focusing on a new identity combination, the woman and scientist identities. In addition, it examines the influence of identity centrality, or importance, as a predictor of interference and moderator of the relation between interference and well-being and science performance. Supporting hypotheses, greater identity interference was related to lower levels of performance and well-being. Furthermore, woman centrality was unrelated to interference for those with a central scientist identity, but for those without a central scientist identity, they were positively related. Although central identities were related to positive outcomes in the absence of interference, the outcomes of all women suffered when interference was high, contrary to the hypothesis. The implications of identity centrality for understanding the negotiation of potentially conflicting identities, and for the retention of women in the sciences, are discussed.     

The psychology of engagement with indigenous identities: a cultural perspective

In a questionnaire study among 124 students at Haskell Indian Nations University, the authors investigated the hypothesis that engagement with Indigenous identity--assessed along three dimensions including degree (identification scale), content (panethnic or tribal nation), and context (reservation or nonreservation)--can serve as a psychological resource for well-being and liberation from oppression. Consistent with this hypothesis, degree of identification was positively correlated with community efficacy and perception of racism. Apparently inconsistent with this hypothesis, degree of identification among students who had resided on a reservation was negatively correlated with the Social Self-Esteem subscale of the Current Thoughts Scale. Rather than evidence against the identity-as-resource hypothesis, this pattern may reflect the cultural grounding of self-esteem and tools designed to measure it.     

Primacy of wholistic processing and global/local paradigm: a critical review.

The question of whether perception is analytic or wholistic is an enduring issue in psychology. The global-precedence hypothesis, considered by many as a modern version of the Gestaltist claim about the perceptual primacy of wholes, has generated a large body of research, but the debate still remains very active. This article reviews the research within the global/local paradigm, and critically analyzes the assumptions underlying this paradigm. The extent to which this line of research contributes to understanding the role of wholistic processing in object perception is discussed. It is concluded that one should be very cautious in making inferences about wholistic processing from the processing advantage of the global level of stimulus structure. A distinction is proposed between global properties, defined by their position in the hierarchical structure of the stimulus, and wholistic properties, defined as a function of interrelations among component parts. It is suggested that a direct comparison between processing of wholistic and component properties is needed to support the hypothesis about the perceptual primacy of wholistic processing.     

Testing a queue hypothesis for the processing of global and local information.

To test whether the advantage for global features in visual perception is stationary throughout the course of processing or is superseded by a local advantage, 6 experiments were conducted in which subjects responded to auditorially presented letter names, while viewing compound visual stimuli. The consistencies of the 2 levels of the compound letters with the auditory stimuli were varied. The requirement with respect to the visual stimulus was manipulated between experiments. The onset asynchrony (SOA) between the visual stimulus and the auditory one was randomized within blocks. Interaction of SOA with consistency of either of the globality levels with the auditory stimulus would indicate lack of stationarity. No such indication was found. Several findings suggest global advantage. The results hold across 3 exposure durations. Findings support the hypothesis of global precedence as well as the claim that it is stationary.     

Complexity of culture: the role of identity and context in bicultural individuals' body ideals

Culture plays an important role in shaping body image, and people from different cultures have different beliefs about what constitutes the "ideal" body type. This study examines the relationship between culture and body ideals in Asian-American and Black-American women. Results from two studies show that subjective cultural identity and situational cultural cues had different relationships with body ideals. Among Asian-American women, identification with Asian culture was related to a thinner body ideal, but exposure to Asian cultural cues (relative to American cultural cues) was related to a thicker body ideal. Among Black-American women, identification with Black culture was related to a thicker body ideal, but exposure to Black cultural cues (relative to American cultural cues) was related to a thinner body ideal. These results have theoretical and practical implications for understanding how internal and external manifestations of culture can differentially influence body image.     

Cultural chameleons and iconoclasts: Assimilation and reactance to cultural cues in biculturals’ expressed personalities as a function of identity conflict

Bicultural individuals vary in the degree to which their two cultural identities are integrated versus conflicting—Bicultural Identity Integration (BII). Past research on attribution biases finds that BII influences the way that biculturals shift in response to cultural primes: integrated biculturals shift assimilatively, whereas conflicted biculturals shift contrastively. Proposing that this reflects assimilation versus reactance responses, we tested whether it extends to shifts in self-perceived personality. In two experiments with Asian-American participants, we found that BII influences the direction of cultural priming effects (assimilation versus contrast) on the personality dimensions of need for uniqueness (Experiment 1) and extraversion (Experiment 2). As hypothesized, high BIIs shifted in a culturally assimilative direction, perceiving the self as more uniqueness-seeking and extraverted following American versus Asian priming, whereas low BIIs shifted in the reverse direction. Implications for research on bicultural identity, priming, personality, organizational and consumer behavior are discussed.     

The integration of Iraqis in two European cities: Emotions and identity work

In this study of Iraqi refugees in Helsinki and Rome, we explore the verbal construction of identity as evidence of the process of integration into a new society. We make use of Snow and Anderson's idea of “identity work” and link it to McCall's idea of “not-me.” The data for this paper derive from a larger comparative study conducted by the second author. They are based on the findings from forty-eight open-ended, semi-structured interviews, half conducted in each city. We argue that despite differences between the two locales regarding such things as the respective welfare regimes and relations with natives, the identity work required for refugees to reinscribe and reconstruct their sense of self was remarkably similar.
