Busting Out: Predictive Brains,Embodied Minds,and the Puzzle of the Evidentiary Veil

Biological brains are increasingly cast as ‘prediction machines’: evolved organs whose core operating principle is to learn about the world by trying to predict their own patterns of sensory stimulation. This, some argue, should lead us to embrace a brain‐bound ‘neurocentric’ vision of the mind. The mind, such views suggest, consists entirely in the skull‐bound activity of the predictive brain. In this paper I reject the inference from predictive brains to skull‐bound minds. Predictive brains, I hope to show, can be apt participants in larger cognitive circuits. The path is thus cleared for a new synthesis in which predictive brains act as entry‐points for ‘extended minds’, and embodiment and action contribute constitutively to knowing contact with the world.     

Learning to fear a second-order stimulus following vicarious learning

Vicarious fear learning refers to the acquisition of fear via observation of the fearful responses of others. The present study aims to extend current knowledge by exploring whether second-order vicarious fear learning can be demonstrated in children. That is, whether vicariously learnt fear responses for one stimulus can be elicited in a second stimulus associated with that initial stimulus. Results demonstrated that children's (5–11 years) fear responses for marsupials and caterpillars increased when they were seen with fearful faces compared to no faces. Additionally, the results indicated a second-order effect in which fear-related learning occurred for other animals seen together with the fear-paired animal, even though the animals were never observed with fearful faces themselves. Overall, the findings indicate that for children in this age group vicariously learnt fear-related responses for one stimulus can subsequently be observed for a second stimulus without it being experienced in a fear-related vicarious learning event. These findings may help to explain why some individuals do not recall involvement of a traumatic learning episode in the development of their fear of a specific stimulus.     

Interpretation of Ambiguity in Children: A Prospective Study of Associations With Anxiety and Parental Interpretations

Interpretation of ambiguity is consistently associated with anxiety in children, however, the temporal relationship between interpretation and anxiety remains unclear as do the developmental origins of interpretative biases. This study set out to test a model of the development of interpretative biases in a prospective study of 110 children aged 5–9 years of age. Children and their parents were assessed three times, annually, on measures of anxiety and interpretation of ambiguous scenarios (including, for parents, both their own interpretations and their expectations regarding their child). Three models were constructed to assess associations between parent and child anxiety and threat and distress cognitions and expectancies. The three models were all a reasonable fit of the data, and supported conclusions that: (i) children’s threat and distress cognitions were stable over time and were significantly associated with anxiety, (ii) parents’ threat and distress cognitions and expectancies significantly predicted child threat cognitions at some time points, and (iii) parental anxiety significantly predicted parents cognitions, which predicted parental expectancies at some time points. Parental expectancies were also significantly predicted by child cognitions. The findings varied depending on assessment time point and whether threat or distress cognitions were being considered. The findings support the notion that child and parent cognitive processes, in particular parental expectations, may be a useful target in the treatment or prevention of anxiety disorders in children.     

Knowing what we can do: actions,intentions, and the construction of phenomenal experience

How do questions concerning consciousness and phenomenal experience relate to, or interface with, questions concerning plans, knowledge and intentions? At least in the case of visual experience the relation, we shall argue, is tight. Visual perceptual experience, we shall argue, is fixed by an agent’s direct unmediated knowledge concerning her poise (or apparent poise) over a currently enabled action space. An action space, in this specific sense, is to be understood not as a fine-grained matrix of possibilities for bodily movement, but as a matrix of possibilities for pursuing and accomplishing one’s intentional actions, goals and projects. If this is correct, the links between planning, intention and perceptual experience are tight, while (contrary to some recent accounts invoking the notion of ‘sensorimotor expectations’) the links between embodied activity and perceptual experience, though real, are indirect. What matters is not bodily activity itself, but our practical knowledge (which need not be verbalized or in any way explicit) of our own possibilities for action. Such knowledge, selected, shaped and filtered by the grid of plans, goals, and intentions, plays, we argue, a constitutive role in explaining the content and character of visual perceptual experience.     

Multiple commitments in the Chinese context: Testing compatibility, cultural, and moderating hypotheses

This paper evaluates the contribution of the multiple constituencies of commitment framework in explaining work attitudes and behaviors in a sample of Chinese manufacturing workers. Findings suggest that the organization, the supervisor, and co-workers were seen by respondents as separate commitment foci. Although the various commitments were moderately positively correlated, they were related differently to the dimensions of organizational citizenship behavior and withdrawal cognitions, in a way which provides support for the “compatibility” hypothesis. There was only limited support for our “cultural” hypothesis. An analysis of interactions between commitments suggested that commitment to supervisor was a stronger positive predictor of protecting company resources and interpersonal harmony when commitment to work group was lower, providing partial support for our moderating hypotheses.     

Combating stereotype threat: The effect of self-affirmation on women’s intellectual performance

The present studies were designed to investigate the effects of self-affirmation on the performance of women under stereotype threat. In Study 1, women performed worse on a difficult math test when it was described as diagnostic of math intelligence (stereotype threat condition) than in a non-diagnostic control condition. However, when women under stereotype threat affirmed a valued attribute, they performed at levels comparable to men and to women in the no-threat control condition. In Study 2, men and women worked on a spatial rotation test and were told that women were stereotyped as inferior on such tasks. Approximately half the women and men self-affirmed before beginning the test. Self-affirmation improved the performance of women under threat, but did not affect men’s performance.     

Psychological defense in anticipation of anxiety: eliminating the potential for anxiety eliminates the effect of mortality salience on worldview defense

A large body of research has shown that when people are reminded of their mortality, their defense of their cultural worldview intensifies. Although some psychological defenses seem to be instigated by negative affective responses to threat, mortality salience does not appear to arouse such affect. Terror management theory posits that the potential to experience anxiety, rather than the actual experience of anxiety, underlies these effects of mortality salience. If this is correct, then mortality-salience effects should be reduced when participants believe they are not capable of reacting to the reminder of mortality with anxiety. In a test of this hypothesis, participants consumed a placebo purported to either block anxiety or enhance memory. Then we manipulated mortality salience, and participants evaluated pro- and anti-American essays as a measure of worldview defense. Although mortality salience intensified worldview defense in the memory-enhancer condition, this effect was completely eliminated in the anxiety-blocker condition. The results suggest that some psychological defenses serve to avert the experience of anxiety rather than to ameliorate actually experienced anxiety.
