Prejudice from thin air: The effect of emotion on automatic intergroup attitudes

Two experiments provide initial evidence that specific emotional states are capable of creating automatic prejudice toward outgroups. Specifically, we propose that anger should influence automatic evaluations of outgroups because of its functional relevance to intergroup conflict and competition, whereas other negative emotions less relevant to intergroup relations (e.g., sadness) should not. In both experiments, after minimal ingroups and outgroups were created, participants were induced to experience anger, sadness, or a neutral state. Automatic attitudes toward the in- and outgroups were then assessed using an evaluative priming measure (Experiment 1) and the Implicit Association Test (Experiment 2). As predicted, results showed that anger created automatic prejudice toward the outgroup, whereas sadness and neutrality resulted in no automatic intergroup bias. The implications of these findings for emotion-induced biases in implicit intergroup cognition in particular, and in social cognition in general, are considered.     

Believing is seeing: the effects of racial labels and implicit beliefs on face perception

Two studies tested whether racial category labels and lay beliefs about human traits have a combined effect on people's perception of, and memory for, racially ambiguous faces. Participants saw a morphed target face accompanied by a racial label (Black or White). Later, they were asked to identify the face from a set of two new morphed faces, one more Black and the other more White than the target. As predicted, entity theorists, who believe traits are immutable, perceived and remembered the target face as consistent with the racial label, whereas incremental theorists, who believe traits are malleable, perceived and remembered the face as inconsistent with the racial label. In Study 2, participants also drew the target face more consistently (entity theorists) or less consistently (incremental theorists) with the racial label. Results of both studies confirm that social variables can affect how physical features are seen and remembered.     

On the malleability of automatic attitudes: combating automatic prejudice with images of admired and disliked individuals.

Two experiments examined whether exposure to pictures of admired and disliked exemplars can reduce automatic preference for White over Black Americans and younger over older people. In Experiment 1, participants were exposed to either admired Black and disliked White individuals, disliked Black and admired White individuals, or nonracial exemplars. Immediately after exemplar exposure and 24 hr later, they completed an Implicit Association Test that assessed automatic racial attitudes and 2 explicit attitude measures. Results revealed that exposure to admired Black and disliked White exemplars significantly weakened automatic pro-White attitudes for 24 hr beyond the treatment but did not affect explicit racial attitudes. Experiment 2 provided a replication using automatic age-related attitudes. Together, these studies provide a strategy that attempts to change the social context and, through it, to reduce automatic prejudice and preference.     

A cross-cultural study of psychosocial aspects of sickle cell disease in the UK and Nigeria

Pain experience, health service utilization and psychological coping in adult patients with sickle cell disease were compared cross-culturally between the UK and Nigeria. Patients in the UK experienced a significantly greater number of pain episodes and of longer duration, with more frequent visits to accident and emergency departments compared with those in Nigeria. The Nigerian patients, on the other hand, applied more psychologically active coping strategies such as distraction to deal with their sickle cell pain in the community. These significant differences are explained in relation to external health locus of control factors including beliefs, and the cost of healthcare in relation to the use of health services. Clinical implications of these findings are also considered.     

Analyzing Machine-Learned Representations: A Natural Language Case Study

As modern deep networks become more complex, and get closer to human-like capabilities in certain domains, the question arises as to how the representations and decision rules they learn compare to the ones in humans. In this work, we study representations of sentences in one such artificial system for natural language processing. We first present a diagnostic test dataset to examine the degree of abstract composable structure represented. Analyzing performance on these diagnostic tests indicates a lack of systematicity in representations and decision rules, and reveals a set of heuristic strategies. We then investigate the effect of training distribution on learning these heuristic strategies, and we study changes in these representations with various augmentations to the training set. Our results reveal parallels to the analogous representations in people. We find that these systems can learn abstract rules and generalize them to new contexts under certain circumstances—similar to human zero-shot reasoning. However, we also note some shortcomings in this generalization behavior—similar to human judgment errors like belief bias. Studying these parallels suggests new ways to understand psychological phenomena in humans as well as informs best strategies for building artificial intelligence with human-like language understanding.     

Contesting (Simonton's) Blind Variation,Selective Retention Theory of Creativity

Over the 50 years since Donald Campbell advanced his Darwinian theory of creative thought, now better known as the blind variation, selective retention (BVSR) theory of creativity, a considerable literature has evolved, involving both support and opposition to the theory. The most prolific support of BVSR theory is due to Dean Keith Simonton. In response to a detailed exposition by Simonton of BVSR theory, a set of cognitive-historical case studies to refute it was presented by Dasgupta; this, in turn, had elicited a response from Simonton. Very recently, Simonton presented an updated version of the theory, which will be called here Simonton's BVSR theory. This article offers two detailed cognitive-historical case studies of actual episodes of technological creativity to challenge and contest BVSR theory as a general theory of creativity.     

Metaphysical Rationalism

The Principle of Sufficient Reason states that everything has an explanation. But different notions of explanation yield different versions of this principle. Here a version is formulated in terms of the notion of a “grounding” explanation. Its consequences are then explored, with particular emphasis on the fact that it implies necessitarianism, the view that every truth is necessarily true. Finally, the principle is defended from a number of objections, including objections to necessitarianism. The result is a defense of a “rationalist” metaphysics, one that constitutes an alternative to the contemporary dogmas that some aspects of the world are “metaphysically brute” and that the world could in so many ways have been different.     

Multidisciplinary creativity: the case of Herbert A. Simon

In the twentieth century, no person epitomized more dramatically the “Renaissance mind” than Herbert A. Simon (1916–2001). In aworking life spanning over 60 years, Simon made seminal contributions to administrative theory, axiomatic foundations of physics, economics, sociology, econometrics, cognitive psychology, logic of scientific discovery, and artificial intelligence. Simon's life of the mind, thus, affords nothing less than a “laboratory” in which to observe and examine at close quarters the phenomenon of multidisciplinary creativity. In this paper, we attempt to shed some light on the nature of Simon's creativity and the nature of his particular Renaissance mind. In particular, we have attempted here to articulate the cognitive style underlying Simon's multidisciplinary creativity.
