Brands on the brain: Do consumers use declarative information or experienced emotions to evaluate brands?

An fMRI study was conducted with unfamiliar and familiar (strong and weak) brands to assess linguistic encoding and retrieval processes, and the use of declarative and experiential information, in brand evaluations. As expected, activations in brain areas associated with linguistic encoding were higher for unfamiliar brands, but activations in brain areas associated with information retrieval were higher for strong brands. Interestingly, weak brands were engaged simultaneously in both processes. Most importantly, activations of the pallidum, associated with positive emotions, for strong brands and activations of the insula, associated with negative emotions, for weak and unfamiliar brands suggested that consumers use experienced emotions rather than declarative information to evaluate brands. As a result, brand experiences should be considered a key driver of brand equity in addition to brand awareness and cognitive associations.     

Perception of racial discrimination and psychopathology across three U.S. ethnic minority groups

To examine the association between the perception of racial discrimination and the lifetime prevalence rates of psychological disorders in the three most common ethnic minorities in the United States, we analyzed data from a sample consisting of 793 Asian Americans, 951 Hispanic Americans, and 2,795 African Americans who received the Composite International Diagnostic Interview through the Collaborative Psychiatric Epidemiology Studies. The perception of racial discrimination was associated with the endorsement of major depressive disorder, panic disorder with agoraphobia, agoraphobia without history of panic disorder, posttraumatic stress disorder, and substance use disorders in varying degrees among the three minority groups, independent of the socioeconomic status, level of education, age, and gender of participants. The results suggest that the perception of racial discrimination is associated with psychopathology in the three most common U.S. minority groups.     

A glass full of optimism: Enrichment effects on cognitive bias in a rat model of depression

Investigations of cognitive biases in animals are conceptually and translationally valuable because they contribute to animal welfare research and help to extend and refine our understanding of human emotional disorders, where biased information processing is a critical causal and maintenance factor. We employed the "learned helplessness" genetic rat model of depression in studying cognitive bias and its modification by environmental manipulations. Using a spatial judgment task, responses to ambiguous spatial cues were assessed before and after environmental enrichment to test whether this manipulation would cause an optimistic shift in emotional state. Twenty-four congenitally helpless and nonhelpless male rats were trained to discriminate two different locations, "rewarded" versus "aversive." After successful acquisition of this spatial discrimination, cognitive bias was probed by measuring responses to three ambiguous locations. Latencies to "reach" and to actively "choose" a goal pot were recorded alongside exploratory behaviors. An overall strain difference was observed, with helpless rats displaying longer "reach" latencies than nonhelpless rats. This implies a "pessimistic" response bias in helpless rats, underscoring their depressive-like phenotype. No strain differences were observed regarding other behavioral measures. Half of the animals were then transferred to enriched cages and retested. Environmental enrichment resulted in reduced "choose" latencies in both rat strains, associating enrichment with more optimistic interpretations of ambiguous cues. Our results emphasize the suitability of cognitive bias measurement for animal emotion assessment. They extend the methodological repertoire for characterizing complex phenotypes and bear implications for animal welfare research and for the use of animal models in preclinical research.     

From top to bottom: spatial shifts of attention caused by linguistic stimuli

Interacting with the world around us involves dealing with constant information input. Thus, humans must selectively filter and focus attention on relevant aspects for the current situation. The current study investigates orientations of attention after words that do not convey spatial information in their meaning (e.g. cloud, shoe). The current study minimizes both the linguistic demands by simply presenting task-irrelevant words and the visual processing demands by implementing a simple target detection task. According to automatic response biases in the motor domain (Lachmair et al. 2011), we hypothesized that words such as cloud produce attention shifts in the direction of the typical location of the word's referent in the world (e.g. cloud up in the sky). Indeed, target detection was facilitated if target location matched the typical location of the word's referent. These findings are strong evidence for the important role of space during language processing, showing that vertical attention is modulated even by task-irrelevant verbal cues.     

A General Model of Preventive and Interventive Self‐Control

The field of self‐control has witnessed an unprecedented boom, not least due to the immense implications of successful and unsuccessful self‐control for people’s lives. However, successful and unsuccessful self‐control can take many different forms, and many conceptual problems have been raised as to what self‐control is about and how to best study it. Integrating different literatures, we provide a general model of self‐control which distinguishes between preventive (i.e., anticipatory) and interventive (i.e., momentary) forms of self‐control. The proposed Preventive‐Interventive Model (PI‐Model) of Self‐Control combines seven basic components: preventive strategies, desire, conflict, control motivation, volition, opportunity constraints, and behavior enactment. The resulting taxonomy helps to distinguish self‐control from standard motivational processes, to define the concept of temptation, and to identify different types of self‐control failure including self‐monitoring failure, motivational self‐control failure, and volitional self‐control failure. Further, the model helps to outline five broad mechanisms through which people may be able to proactively boost self‐control success.     

Truthmaking, Recombination, and Facts Ontology

The idea of truthmakers is important for doing serious metaphysics, since a truthmaker principle can give us important guidance in finding out what we would like to include into our ontology. Recently, David Lewis has argued against Armstrong’s argument that a plausible truthmaker principle requires us to accept facts. I would like to take a close look at the argument. I will argue in detail that the Humean principle of recombination on which Lewis relies is not plausible (independently of the issue of facts). Then I will show that the right truthmaker principle that vindicates facts is superior to the modified truthmaker principle that Lewis has proposed. This will lead into the topic of being and existence. It turns out that truthmaking and facts are plausible, well suited for one another, and very coherent with a plausible conception of being.
