Perceptual load affects change blindness in a real‐world interaction

Change blindness is the striking inability to detect seemingly obvious changes that occur between views of a scene. The current study assessed perceptual load as a factor that may affect change blindness for human faces. The study had participants (n = 103) interact with a researcher in a testing room that imposed low or high perceptual load. Midway through the conversation, the researcher was replaced by another person. Thirty‐nine percent of participants failed to detect the change. There was a significant effect of perceptual load, with greater change detection under low load (71%) than high load (52%). This research suggests that the perceptual load imposed by a task may have a significant effect on the likelihood of change blindness and ought to be considered in future research.     

Context and Perceptual Salience Influence the Formation of Novel Stereotypes via Cumulative Cultural Evolution

We use a transmission chain method to establish how context and category salience influence the formation of novel stereotypes through cumulative cultural evolution. We created novel alien targets by combining features from three category dimensions—color, movement, and shape—thereby creating social targets that were individually unique but that also shared category membership with other aliens (e.g., two aliens might be the same color and shape but move differently). At the start of the transmission chains each alien was randomly assigned attributes that described it (e.g., arrogant, caring, confident). Participants were given training on the alien‐attribute assignments and were then tested on their memory for these. The alien‐attribute assignments participants produced during test were used as the training materials for the next participant in the transmission chain. As information was repeatedly transmitted an increasingly simplified, learnable stereotype‐like structure emerged for targets who shared the same color, such that by the end of the chains targets who shared the same color were more likely to share the same attributes (a reanalysis of data from Martin et al., 2014 which we term Experiment 1). The apparent bias toward the formation of novel stereotypes around the color category dimension was also found for objects (Experiment 2). However, when the category dimension of color was made less salient, it no longer dominated the formation of novel stereotypes (Experiment 3). The current findings suggest that context and category salience influence category dimension salience, which in turn influences the cumulative cultural evolution of information.     

Engaging with the Hatred of the Other: Personal Reflections Discussion of “States of Exile and Marginalization”

Drawing upon experiences associated with racialized tensions and interactions related to living in neocolonial, post-apartheid South Africa, I engage with Gillian Straker’s complex paper on “States of Exile and Marginalization” (this issue) as elaborated in response to Moffatt’s film Night Cries. In particular, I question what it means to receive the hatred of the other in contexts in which previous relations of power become challenged and inverted and grapple with how it may be possible to sustain a relational ethics in such instances. Straker’s reading of the tension between the real and the symbolic in Night Cries and what this signals for modes of expression, multiplicity of meaning, and potentialities in relating is also highlighted.     

Perceptions of Academic Dishonesty in a South African University: A Q-Methodology Approach

The prevalence of academic dishonesty is a matter of considerable concern for institutions of higher education everywhere. We explored students’ perceptions of academic dishonesty using Q methodology, which provides insights that are different from those obtained through surveys or interviews. South African students ranked 48 statements, giving reasons why students cheat, on an 11-column grid, anchored by strongly agree and strongly disagree. Q factor analysis was used to identify groups of individuals who share the same perspective. The three perspectives that emerged viewed academic dishonesty as (a) moral transgressions, (b) pressure transgressions, or (c) confused transgressions. These suggest different approaches to addressing the issue.     

Spirituality and aging: How worship communities of older adults sustain their faith in the absence of traditional ordained leadership

ABSTRACT

This article considers how older Christians (aged over 70) exercise worship in an environment of shared ministry. Specifically, the Local Shared Ministry Units (LSMU) model of worship within the Auckland Diocese of the Anglican Church in Aotearoa/New Zealand and Polynesia (Auckland Diocese). A collective case study approach was used, and individual members of four LSMUs were interviewed with the resulting comments treated as a collective case study. The findings indicate these older adults are still seeking faith formation, do not regard themselves as fully formed spiritually, and use personal prayer in particular to enhance and nourish their faith growth.     

Cognitive bias modification as a strategy to reduce children's fears and concerns about the secondary school transition

Background and objectives: Cognitive Bias Modification of Interpretations (CBM-I) has emerged as an anxiety-reducing tool for children and adolescents, targeting maladaptive interpretations of everyday situations. This literature falls short of addressing whether the effects of CBM-I extend to worries about a real-life stressor, such as a school transition. Design: The study comprised a between-groups design comparing the effects of CBM-I to an active control (AC) intervention in children. Method: We recruited 38 children within two months of their primary–secondary school transition and investigated the capacity for multi-session, parent-administered CBM-I, compared to an AC condition, to modify cognitive style and reduce anxiety symptoms and school concerns. Results: While benign interpretations increased significantly and negative interpretations tended to decrease following CBM-I, both interventions significantly reduced anxiety symptoms and school concerns. Conclusions: These findings indicate that anxiety-reducing effects of CBM-I in children extend to a real life stressful event, but that equivalent anxiety reduction may be achieved through exposure to potentially worrying situations and parent–child interaction in the absence of bias modification.     

The effects of mindfulness interventions on prenatal well-being: A systematic review

Objective: Low well-being during pregnancy can have significant adverse outcomes for mother and child. The effects of mindfulness interventions on prenatal maternal well-being are increasingly examined but outcomes have yet to be systematically evaluated. The aims of the current paper are to systematically evaluate intervention effects and current research approaches with pregnant groups.

Design: A systematic review of eight studies examining mindfulness intervention effects on prenatal well-being.

Results: Findings indicate potential benefits of mindfulness interventions for reducing levels of depression, anxiety and negative affect during pregnancy. There is also evidence for improved self-compassion and perceived childbirth self-efficacy. Further, these effects may be more pronounced for vulnerable groups, such as women currently experiencing low prenatal well-being. Less consistent findings were observed for stress, and positive affect. Variations in research design, gestational characteristics, timing of assessments and outcome measurement may explain some inconsistencies in the extant literature.

Conclusion: Mindfulness interventions present a potentially useful means to improve prenatal well-being but improved methodological quality is essential to rigorously examine intervention effects.     

Specialised higher-level mechanisms for facial-symmetry perception: evidence from orientation-tuning functions

Bilateral symmetry is important in many perceptual analyses from low-level figure-ground segmentation to higher-level face and object perception. Despite the success of low-level, image-based symmetry-detection models, these may not provide a complete account of symmetry perception. Better symmetry detection and stronger preferences for symmetry in upright faces than comparable patterns (e.g. inverted faces) that do not engage specialised face-coding mechanisms suggest a contribution of higher-level mechanisms to symmetry perception. We replicated better symmetry detection and stronger symmetry preferences for upright than inverted faces in experiment 1, and examined their orientation tuning in more detail in experiment 2. Decreasing performance as faces are mis-oriented away from the canonical upright orientation is the signature of specialised face-processing mechanisms, which are engaged less effectively as faces are mis-oriented. Lower-level symmetry-detection mechanisms, which operate better with vertical than horizontal, and horizontal than oblique, axes of symmetry would produce a W-shaped orientation-tuning function. Identical orientation-tuning functions were obtained for symmetry detection and preferences. Both declined with increasing mis-orientation over the 0 degrees-135 degrees range, consistent with a contribution from specialised face-coding mechanisms. Both increased from 135 degrees to 180 degrees, consistent with reliance on lower-level image-based mechanisms for severely misoriented faces. Taken together, the results implicate specialised, higher-level mechanisms in the detection of, and preference for, facial symmetry.     

Exploring the specificity of age-related differences in theory of mind tasks

Tasks assessing theory of mind (ToM) and non-mental state control tasks were administered to young and older adults to examine previous contradictory findings about age differences in mental state decoding. Age differences were found on a verbal ToM task after controlling for vocabulary levels. Older adults achieved significantly lower scores than did younger adults on static and dynamic visual ToM tasks, and a similar pattern was found on non-ToM control tasks. Rather than a specific ToM deficit, older adults exhibited a more general impairment in the ability to decode cues from verbal and visual information about people.     

Six-week postpartum maternal self-criticism and dependency and 4-month mother-infant self- and interactive contingencies

Associations of 6-week postpartum maternal self-criticism and dependency with 4-month mother-infant self- and interactive contingencies during face-to-face play were investigated in 126 dyads. Infant and mother face, gaze, touch, and vocal quality were coded second by second from split-screen videotape. Self- and interactive contingencies were defined as auto- and lagged cross-correlation, respectively, using multilevel time-series models. Statistical significance was defined as p<.05. Regarding self-contingency, (a) more self-critical mothers showed primarily lowered self-contingency, whereas their infants showed both lowered and heightened, and (b) infants of more dependent mothers showed primarily lowered self-contingency, whereas findings were absent in mothers. Regarding interactive contingency, (a) more self-critical mothers showed lowered attention and emotion contingencies but heightened contingent touch coordination with infant touch, and (b) more dependent mothers and their infants showed heightened facial/vocal interactive contingencies. Thus, maternal self-criticism and dependency have different effects on mother-infant communication.
