Improving Discrimination and Face Matching with Caricature

Identification of faces from photographs is a common security measure, but matching unfamiliar faces produces high rates of error. Caricatures of familiar people are highly identifiable because they exaggerate distinctive features. We investigated whether exaggerating unfamiliar faces through caricaturing could also improve face‐matching accuracy. In Experiment 1, face‐matching arrays were caricatured relative to an average by 30%, 50% and 70%. Correct rejection of the target‐absent arrays was improved at all levels. Accurate matches increased at 30%, but at 70%, the transformation was too extreme, and all of the arrays were more likely to be rejected. In Experiment 2, photographic identification (ID) images were caricatured by 30% and 50% and matched to life‐size photographs. Rejection of foils improved, but the ID of matching images was impaired. Modest levels of caricature may improve discrimination in unfamiliar face matching, but at stronger levels, a conservative response bias may inhibit accurate ID.

Multiple repetition priming of faces: Massed and spaced presentations

Previously viewing a face typically leads to a decrease in the amount of time taken to later identify it (“repetition priming”). Five repetition priming experiments are reported, which investigate whether multiple presentations of a face increase the amount of repetition priming. The results demonstrate similar amounts of priming from massed multiple presentations of the same face or a series of different images (freeze frames selected from a moving clip and presented in sequence), compared with a single unchanging presentation (Experiments 1 and 2). This is true even when different images are presented at prime and test (Experiment 3). However when multiple presentations were presented in a spaced fashion, with one or more intervening items between each repeat, there was significantly more priming in the multiple than single presentation condition (Experiment 4). This was true even when the face was named only once in both the multiple and single spaced conditions (Experiment 5). The results are discussed in relation to face motion.     

The effect of controllability and causality on counterfactual thinking

Previous research on counterfactual thoughts about prevention suggests that people tend to focus on enabling rather than causing events and controllable rather than uncontrollable events. Two experiments explore whether counterfactual thinking about enablers is distinct from counterfactual thinking about controllable events. We presented participants with scenarios in which a cause and an enabler contributed to a negative outcome. We systematically manipulated the controllability of the cause and the enabler and asked participants to generate counterfactuals. The results indicate that when only the cause or the enabler is controllable participants undid the controllable event more often. However, when the cause and enabler are matched in controllability participants undid the enabler slightly more often. The findings are discussed in the context of the mental model, functional and judgement dissociation theories as well as previous research on counterfactual thinking. The importance of controllability and possible reasons for the special role of enablers are considered.     

Defining health and unhealthiness: Perceptions held by Native American Indians with persistent mental illness1

Discrepancies in definitions of health exist. These discrepancies, if not acknowledged, create major communication gaps between health-care professionals and their clients, which interferes with the provision of culturally responsive care. The purpose of this study was to understand how Native American Indians experiencing persistent mental illness (PMI) define/describe being healthy and being unhealthy. Grounded theory design was used in conducting data gathering (semistructured interviews) and analysis (constant comparative) because the study focuses on generating social/psychological phenomena or process. Forty-four audiotaped interviews were conducted and transcribed. Symbolic interactionism is this study's framework. During data analysis, health emerged as being in balance/equilibrium, having a sense of harmony, and not being out of control of spiritual, cognitive, emotional, and physical domains. Furthermore, as this study reflects, the modified Circle of Wellness model emerges as a better fit for Native American Indians with PMI than the traditional Medicine Wheel because it more effectively presents the social nature/needs and the centrality of spiritualism of this population. Clearly, deficits in healthy social environments and relationships affect the ability of a Native American Indian with PMI to maintain health. To provide culturally competent care, professionals and native healers need to work the integration of spirituality into treatment processes, and advocate the creation and maintenance of healthy environments for improved social opportunities.     

“Chaotic soup of politics:” a Native American Indian mental health perspective

Through a grounded theory process, tribal politics emerged as a core theme from interviews with mental health providers (MHPs) and Native American Indian people experiencing persistent mental illness (PMI). Interviews were conducted over a four-year period with 13 Indian MHPs and administrators, and 18 persons experiencing PMI. Symbolic Interactionism was the informing framework. Findings indicate that reservation life promotes a high immersion in Eurocentric politics, which negatively affects the person with PMI in their maintenance of a healthy spirit balance. To be effective, MHPs need immersion in; the oneness of culture, spirituality, and politics of the community; knowledge of the tribal history; and communication with elders/spiritual leaders. This personal growth could facilitate provision of culturally responsive care needed for a client's navigation of intergovernmental regulations. MHPs should work for adequate funding policies of human service centers while supporting the establishment of indigenous governing practices through tribal sovereignty.     

Toward an Ecological Theory of Concepts

Psychology has had difficulty accounting for the creative, context-sensitive manner in which concepts are used. We believe this stems from the view of concepts as identifiers rather than bridges between mind and world that participate in the generation of meaning. This article summarizes the history and current status of concepts research and provides a nontechnical summary of work toward an ecological approach to concepts. We outline the rationale for applying generalizations of formalisms originally developed for use in quantum mechanics to the modeling of concepts, showing how it is because of the role of context that deep structural similarities exist between the two. A concept is defined not just in terms of exemplary states and their features or properties but also by the relational structures of these properties and their susceptibility to change under different contexts. The approach implies a view of mind in which the union of perception and environment drives conceptualization, forging a web of conceptual relations or “ecology of mind.”     

Effective regulation of affect: An action control perspective on emotion regulation

The present review adopts an action control perspective on emotion regulation, contextualising the gap between emotion control goals (e.g., I want to remain calm) and emotional outcomes (e.g., anger, anxiety, and aggression) in terms of the broader literature on goal pursuit. We propose that failure to effectively regulate emotions can result from difficulties with the self-regulatory tasks of (i) identifying the need to regulate, (ii) deciding whether and how to regulate, and (iii) enacting a regulation strategy. Next we review evidence that a technique traditionally associated with regulating behavioural goals (forming implementation intentions or “if-then” planning) can help to overcome these difficulties. Meta-analysis indicated that forming implementation intentions is effective in modifying emotional outcomes, with a large effect relative to no regulation instructions (k = 21, N = 1306 d ₊ = 0.91, 95% CI = 0.61 to 1.20) and a medium-sized effect relative to goal intention instructions (k = 29, N = 1208, d ₊ = 0.53, 95% CI = 0.42 to 0.65). Our conclusion is that research on emotion regulation might benefit from an action control perspective and the interventions that this perspective offers.     

Mind-wandering and negative mood: Does one thing really lead to another?

Mind-wandering is closely connected with negative mood. Whether negative mood is a cause or consequence of mind-wandering remains an important, unresolved, issue. We sought to clarify the direction of this relationship by measuring mood before and after mind-wandering. We also measured the affective content, time-orientation and relevance of mind-wandering to current concerns to explore whether the link between mind-wandering and negative mood might be explained by these characteristics. A novel experience-sampling technique with smartphone application prompted participants to answer questions about mind-wandering and mood across 7 days. While sadness tended to precede mind-wandering, mind-wandering itself was not associated with later mood and only predicted feeling worse if its content was negative. We also found prior sadness predicted retrospective mind-wandering, and prior negative mood predicted mind-wandering to current concerns. Our findings provide new insight into how mood and mind-wandering relate but suggest mind-wandering is not inherently detrimental to well-being.     

Daily fluctuations in the affective states of dancers: A cross-situational test of basic needs theory

ObjectivesThis study tested the generalizability of basic needs theory (BNT; Deci & Ryan, 2000) across situations in which dancers learn and perform within vocational dance. Specifically, we examined the inter-relationships between daily and typical perceptions of autonomy support, basic psychological need satisfaction, and changes in affective states, across dance situations that were divergent in their learning and evaluative potential (dance classes, rehearsals, and performances). Genre differences were also examined.DesignA one-month diary study examined the inter-relationships between typical and daily perceptions of autonomy support, basic psychological need satisfaction and positive and negative affect among dancers studying three distinct genres and in three situations (classes, rehearsals, performances).MethodFifty-five dancers completed a series of scales tapping the variables of interest. Abbreviated versions of the scales were completed before (affective states) and after (affective states, basic needs and autonomy support) dance classes, rehearsals and performances over four weeks. Analyzes tested the BNT sequence across the learning and performance situations. Interactions between typical and state experiences were tested. Cross-genre comparisons were also made.ResultsResults partially supported the BNT sequence across classes, rehearsals and performances. There were situational differences in the salience of each need as a predictor of affective states. When comparing genres, some differences were also found in perceived autonomy support, basic need satisfaction and affective states.ConclusionsFindings point to the importance of promoting autonomy supportive dance teaching to facilitate dancers' day-to-day experiences of well-being.
