The psychology of face construction: Giving evolution a helping hand

Face construction by selecting individual facial features rarely produces recognisable images. We have been developing a system called EvoFIT that works by the repeated selection and breeding of complete faces. Here, we explored two techniques. The first blurred the external parts of the face, to help users focus on the important central facial region. The second, manipulated an evolved face using psychologically‐useful ‘holistic’ scales: age, masculinity, honesty, etc. Using face construction procedures that mirrored police work, a large benefit emerged for the holistic scales; the benefit of blurring accumulated over the construction process. Performance was best using both techniques: EvoFITs were correctly named 24.5% on average compared to 4.2% for faces constructed using a typical ‘feature’ system. It is now possible, therefore, to evolve a fairly recognisable composite from a 2 day memory of a face, the norm for real witnesses. A plausible model to account for the findings is introduced.

How content and co‐viewers elicit emotional discomfort in moviegoing experiences: Where does the discomfort come from and how is it handled?

Although watching movies is typically enjoyable, they also can elicit discomfort. The present studies investigated what makes some moviegoing experiences emotionally uncomfortable. Using autobiographical memory (Study 1) and scenarios/vignettes methodology (Study 2), young adults remembered watching a movie that had made them uncomfortable or responded to scenarios about watching a particular type of movie with particular co‐viewers (e.g. violent movie with one's spouse). Movies eliciting discomfort were most often dramas (39%) or comedies (26%). Discomfort most often arose from content, particularly fairly explicit sex or violence, and secondarily from the presence of co‐viewers. Often the two interacted, for example, being uncomfortable watching explicit sex with one's parents. In terms of dealing with the discomfort, women were overall more direct and men more avoidant. A sizable minority was glad they had seen the film, in spite of the discomfort, and was open to seeing it again. Arguing from converging evidence, these different methodologies produced consistent results. Copyright © 2010 John Wiley & Sons, Ltd.     

The analytic state of consciousness as a form of play and a foundational transference

The analytic state of consciousness is a particular regressive altered state in the patient characterized by an increased sensitivity and reactivity to impressions arising from both the inner world and the analyst, a heightened sense of dependence and vulnerability, a permeability of boundaries in regard to the analyst, and a shift toward functioning on the basis of omnipotent fantasy in the analytic relationship. These changes are accompanied by a feeling of realness of one's psychic reality, but without any true loss of reality testing. Based on an analysis of the structure of play, this state can itself be understood as a kind of play; it serves as a foundational transference underlying more specific transference manifestations; and it is central to the analytic process. Over time, in response to physical aspects of the analytic setting, its safety, the analyst's emotional accompaniment, and a generally restrained analytic stance (an issue I discuss in some detail), it emerges in a more developed form that promotes symbolization and ownership of aspects of self, greater emotional presence, and a deeper sense of meaning in one's experience. Additionally, the concept of the analytic state of consciousness provides a new look at the role of abstinence and frustration in analytic process.     

Contrasting graded effects of semantic similarity and association across the concreteness spectrum

Evidence from healthy individuals and neuropsychological patients with deep dyslexia or semantic refractory access dysphasia suggests that abstract and concrete concepts have different dependencies upon associative and similarity-based representational frameworks. However, the importance of information about semantic similarity for concepts that lie across the full concreteness spectrum has not been investigated. Here we report the performance of healthy individuals on an odd-one-out task involving semantically related word triplets that showed continuous variation for the key variables of concreteness, similarity strength, and association strength. In addition, data from a stroke aphasic patient tested on a matching-to-sample task based on the same abstract, middle-concreteness, and concrete stimuli are also presented. The effects of similarity and association strength upon performance were both shown to interact significantly with concreteness, but in opposite directions. The effect of semantic similarity increased with concreteness but the effect of association decreased with concreteness. This research provides further evidence for the proposal that abstract and concrete words have different dependencies upon associative and similarity-based information. It also develops the proposal by providing data that are consistent with a graded and not binary or ungraded model of the relationship between concreteness and these two forms of semantic relationship.     

Mutual forbearance,the representativeness heuristic and airline safety

This paper investigates the impact of airline crashes on fares and enplanement over the period 1984–1997. Empirical evidence suggests that none of the large carriers seem to initiate price wars with other large rivals involved in crashes, suggesting mutual forbearance. In contrast, small carriers raise their fares in response to small rivals’ crashes, perhaps commanding higher premiums due to their perceived higher safety level and in anticipation of consumer switching. Further estimation results suggest that only a small fraction of passengers form perceptions about crashes according to the representativeness heuristic. Moreover, large rivals’ crashes are associated with no consumer switching across other large carriers but are associated with enplanement losses for small carriers. The findings suggest that consumer perceptions raise important concerns about the challenges that carriers, especially the smaller ones, may face in depicting their true safety level to consumers whose vision may have been blurred by representativeness bias. Nevertheless, although consumers do not necessarily treat crashes as random events, large carriers may breathe a sigh of relief about the extent of consumer panic and overreaction.     

Parallel, independent attentional control settings for colors and shapes

Attentional capture can be contingent on attentional control settings (ACSs), such that peripheral cues influence processing for a subsequent target only when they share a critical feature with the target. Our previous demonstration that two ACSs from within the same feature category can be maintained simultaneously allows us to investigate the processing stage at which such ACSs are implemented. We compared the relative efficacy of ACSs from two different feature categories (shape and color) that are associated with different levels within the visual processing hierarchy. Participants were instructed to respond to one of two colors at one location and one of two shapes at another location, while ignoring the nontarget color and shape. We observed that spatial capture was modulated by whether the cues fit an ACS, with slightly greater contingent capture effects for ACSs defined by color than by shape. Thus, two ACSs from different feature sets (color and shape) can be maintained in parallel, although effectiveness of the control set varied with the type of feature.     

Isoluminant motion onset captures attention

In their 2003 article, Abrams and Christ found that the onset of motion captured attention more effectively than either the offset of motion or continuous motion. Abrams and Christ conceptualized the capture to be occurring at a level higher than does detection of luminance changes in the stimulus. To examine this claim, in the present experiments we replicated their critical experiment but used isoluminant stimuli, which do not produce the low-level luminance transients typically associated with motion. Under isoluminant conditions, we found a pattern of results very similar to that found previously with luminance-defined stimuli, indicating that attention can be prioritized on the basis of perceived motion onset by an object in the absence of low-level luminance transients. This may reflect an evolutionary adaptation to bias attention toward objects that exhibit characteristics of animacy, such as abruptly changing from a static to a dynamic state.     

Reflexive orienting to gaze is not luminance dependent

In the investigation of reflexive orienting to cues, two major theories have emerged: One proposes that transients created by the cue trigger attentional shifts, whereas the other argues that object changes are responsible for instigating orienting. In the present study, we examined whether luminance transients produced by the cue can generate reflexive orienting to gaze. Using a temporal order judgment paradigm under luminant or subjectively equiluminant conditions, participants judged which of two peripheral targets onset first. An uninformative gaze cue served to reflexively shift attention toward one object location, thereby temporally prioritizing the target presented there. The results revealed that attention was successfully shifted toward the cued object, as was evidenced by the participants’ selecting the cued object as appearing first significantly more often than the uncued object, even when the two onset simultaneously. Critically, the results were comparable across luminance conditions. Our findings reveal that luminance transients are not necessary for triggering orienting to gaze cues. We suggest that the orienting observed here can be better explained via an object-based hypothesis whereby object changes, not transients, trigger reflexive orienting.     

How the behavioral approach system predicts everyday life outcomes

This study tested crucial components of Gray's reinforcement sensitivity theory that have generally been overlooked in the literature. We tested whether the perceived amount of reward moderates the behavioral approach system (BAS) and the importance of reward mediates BAS in the prediction of job satisfaction and organizational commitment. Results from 514 participants employed in part-time and full-time jobs provided support for our model, such that the indirect effect of BAS through the importance of reward was strongest when reward was provided. This model advances our understanding of reinforcement sensitivity theory and offers a solid foundation for predicting outcomes in everyday life.
