Context specificity of inhibitory control in dogs

Across three experiments, we explored whether a dog’s capacity for inhibitory control is stable or variable across decision-making contexts. In the social task, dogs were first exposed to the reputations of a stingy experimenter that never shared food and a generous experimenter who always shared food. In subsequent test trials, dogs were required to avoid approaching the stingy experimenter when this individual offered (but withheld) a higher-value reward than the generous experimenter did. In the A-not-B task, dogs were required to inhibit searching for food in a previously rewarded location after witnessing the food being moved from this location to a novel hiding place. In the cylinder task, dogs were required to resist approaching visible food directly (because it was behind a transparent barrier), in favor of a detour reaching response. Overall, dogs exhibited inhibitory control in all three tasks. However, individual scores were not correlated between tasks, suggesting that context has a large effect on dogs’ behavior. This result mirrors studies of humans, which have highlighted intra-individual variation in inhibitory control as a function of the decision-making context. Lastly, we observed a correlation between a subject’s age and performance on the cylinder task, corroborating previous observations of age-related decline in dogs’ executive function.     

Recognition theory and global poverty

So far, recognition theory has focused its attention on modern capitalism and its formation in richer Western societies and has neglected issues of global poverty. A brief sketch of Axel Honneth's recognition theory precedes an examination of how the theory can contribute to a better understanding of global poverty, and justice in relation to poverty. I wish to highlight five ways in which recognition theory can enrich our inventory of theories dealing with global poverty and justice: It emphasizes the importance of giving victims of poverty due weight in theorizing about poverty. It provides a vocabulary to conceptualize the experiences of suffering by poverty in terms of misrecognition. It highlights the importance of legal recognition and of actually having certain rights in order to be respected. It bases its critique of poverty on a particular idea of justice and how it should unfold. Finally, recognition theory demands that the poor must be involved in decision-making processes and their agency has to be recognized, respected, and socially esteemed in order to overturn injustice.     

Detecting meaning in RSVP at 13 ms per picture

The visual system is exquisitely adapted to the task of extracting conceptual information from visual input with every new eye fixation, three or four times a second. Here we assess the minimum viewing time needed for visual comprehension, using rapid serial visual presentation (RSVP) of a series of six or 12 pictures presented at between 13 and 80 ms per picture, with no interstimulus interval. Participants were to detect a picture specified by a name (e.g., smiling couple) that was given just before or immediately after the sequence. Detection improved with increasing duration and was better when the name was presented before the sequence, but performance was significantly above chance at all durations, whether the target was named before or only after the sequence. The results are consistent with feedforward models, in which an initial wave of neural activity through the ventral stream is sufficient to allow identification of a complex visual stimulus in a single forward pass. Although we discuss other explanations, the results suggest that neither reentrant processing from higher to lower levels nor advance information about the stimulus is necessary for the conscious detection of rapidly presented, complex visual information.     

Understanding age-related reductions in visual working memory capacity: Examining the stages of change detection

Visual working memory (VWM) capacity is reduced in older adults. Research has shown age-related impairments to VWM encoding, but aging is likely to affect multiple stages of VWM. In the present study, we recorded the event-related potentials (ERPs) of younger and older adults during VWM maintenance and retrieval. We measured encoding-stage processing with the P1 component, maintenance-stage processing with the contralateral delay activity (CDA), and retrieval-stage processing by comparing the activity for old and new items (old–new effect). Older adults showed lower behavioral capacity estimates (K) than did younger adults, but surprisingly, their P1 components and CDAs were comparable to those of younger adults. This remarkable dissociation between neural activity and behavior in the older adults indicated that the P1 and CDA did not accurately assess their VWM capacity. However, the neural activity evoked during VWM retrieval yielded results that helped clarify the age-related differences. During retrieval, younger adults showed early old–new effects in frontal and occipital areas and a late central–parietal old–new effect, whereas older adults showed a late right-lateralized parietal old–new effect. The younger adults’ early old–new effects strongly resembled an index of perceptual fluency, suggesting that perceptual implicit memory was activated. The activation of implicit memory could have facilitated the younger adults’ behavior, and the lack of these early effects in older adults may suggest that they have much lower-resolution memory than do younger adults. From these data, we speculated that younger and older adults store the same number of items in VWM, but that younger adults store a higher-resolution representation than do older adults.     

The persistence of distraction: A study of attentional biases by fear,faces, and context

Efficient processing of the visual world requires that distracting items be avoided, or at least rapidly disengaged from. The mechanisms by which highly salient, yet irrelevant, stimuli lead to distraction, however, are not well understood. Here, we utilized a particularly strong type of distractor—images of human faces—to investigate the mechanisms of distraction and the involuntarily biasing of attention. Across three experiments using a novel discrimination task, we provided new evidence that the robust distraction triggered by faces may not reflect enhanced attraction but, instead, may reflect an extended holding of attention. Specifically, the onset of a task-irrelevant distractor initially impaired target performance regardless of the identity of that distractor (fearful faces, neutral faces, or places). In contrast, an extended period of distraction was observed only when the distractor was a face. Our results thus demonstrate two distinct mechanisms contributing to distraction: an initial involuntary capture to any sudden event and a subsequent holding of attention to a potentially meaningful, yet task-irrelevant stimulus—in this case, a human face. Critically, the latter holding of attention by faces was not unique to fearful faces but also occurred for neutral faces. The present results dissociate attentional capture from hold in another way as well, since the capture occurred regardless of the nature of the distractors, but the extended holding of attention was dependent upon the ongoing distractor context.     

Perpetuating Stereotypes: A Study of Gender,Family, and Religious Life in Jewish Children's Books

This paper examines award‐winning Jewish children's literature as a medium to explore how religiosity gets constructed differently for men and women. We analyze three decades of winners of the Sydney Taylor Jewish Book Award, a prestigious annual award given by the Association of Jewish Libraries to an outstanding Jewish children's book. We demonstrate how these award‐winning books produce and perpetuate gendered religious stereotypes that associate men with agency and women with communion. We also show how these books construct images of a “domestic Judaism” for women and a “public Judaism” for men and how women have been symbolically annihilated from the titles and central character roles in these books. Drawing on Cecilia Ridgeway's ( 2011 ) gender‐framing perspective, we argue that the gender stereotypes evident in these books matter to society because they produce and enforce gender inequalities in religiousness.     

Focused and fired up: Narrowed attention produces perceived proximity and increases goal-relevant action

Insufficient physical activity contributes to rising obesity rates. We tested one social cognitive strategy aimed at increasing physical activity in the environment. Specifically, we tested whether attentional narrowing can shift people’s perceptual representations of the environment and improve exercise behavior. Participants who adopted a narrow focus of attention, compared to participants who looked around the environment as they naturally would, perceived a target as physically closer (Studies 1, 2). In addition, narrowed attention reduced the time required to walk to a finish line and increased subjective ease of physical task performance, two markers of improved exercise (Study 2). We discuss implications of attentional strategies for perception and action in regards to health and fitness.     

“Why me?”: Low-Income Women’s Poverty Attributions,Mental Health,and Social Class Perceptions

Although much is known about broad societal attitudes toward poverty, less is known about how women perceive their own poverty. We sought to examine the types of self attributions low-income women make about their poverty, as well as the association of self poverty attributions to women’s mental health and upward mobility beliefs. Using close-ended questions in a community sample of 66 low-income mothers from the Midwestern United States, we found these women were most likely to attribute their poverty to issues related to having children, their romantic relationships, and structural/government blame. The least endorsed attributions for poverty were fatalistic and individualistic reasons. Attributing one’s poverty to children and structural reasons was related to greater depression, and attributing one’s poverty to romantic relationships and structural reasons was related to greater anxiety. Moreover, attributing one’s poverty to children and romantic relationships was positively related to upward mobility beliefs, whereas individualistic attributions were negatively related to upward mobility beliefs. Understanding how women view their poverty and upward mobility can help to improve interventions and policies aimed at low-income women.     

The good,the bad and the effective: a meta-analytic examination of selling orientation and customer orientation on sales performance

The concept of customer orientation (CO) is a focal construct in marketing and sales literature. Saxe and Weitz introduced CO to contrast the traditional high-pressure approach to sales (selling orientation). This study synthesizes empirical evidence from 1982 to 2013 to provide insight into the antecedents and consequences of both CO and selling orientation (SO). A conceptual meta-analytic model based on research into interpersonal motive models is proposed and tested using effect sizes from 126,790 salesperson survey responses to advance theory development on our understanding of how SO and CO behaviours affect organizations. Findings show that adaptive selling mediates the impact of both SO and CO which has important practical implications for hiring and training salespeople. Furthermore, this study shows that goal orientations are antecedents of SO and CO and that the impact of SO on job performance varies by customer type.     

The Waiter Spit in My Soup! Antecedents of Customer-Directed Counterproductive Work Behavior

Although researchers have explored organizational and insider targets of counterproductive work behavior (CWB), no studies to date have examined customers as targets. The current study aimed to test a model of antecedents to CWB unique to service worker experiences, including customer stressors, emotional dissonance, and emotional exhaustion. We tested our model with 438 restaurant and bar employees. Results demonstrated that customer stressors were more strongly correlated with customer-directed CWB than with interpersonal or organizational CWB, and customer stressors had direct and indirect effects on customer-directed CWB through experiences of emotional dissonance and exhaustion.
