Evidence for the persistence of visual guidance information

An earlier study from our laboratory provided initial support for the hypothesis that information facilitating visual guidance persists in the absence of retinal stimulation. The present study supports and extends this hypothesis with three experiments in which visually occluded subjects positioned a point of light at the location of a previously viewed target and also walked in the direction of a previously viewed path. In both tasks, performance was possible following occlusion, and in all cases, performance slowly and significantly decreased with longer durations of occlusion. This decay in performance was gradual and had a “half-life” of greater than 15 sec. Absolute performance was correlated across tasks. The effect of occlusion on absolute error in the localization performance was relatively stable within individuals over a 3-week period. The biological utility of guidance information persistence is discussed along with implications for space constancy, illusions of motion, and problems of disorientation.     

“Avant‐Garde of What?”: Surrealism Reconceived as Political Culture

However we may judge avant-garde art when we meet it, for us the phenomenon and idea are so present and evident that we do not stop, even momentarily, to wonder if we might be dealing with an illusion or an appearance rather than a reality, with a myth or a superstition rather than a concept.     

“I was and still am”: Narratives of Bisexual Marking in the #StillBisexual Campaign

This research investigated narratives of bi-erasure and bisexual marking by considering 53 video confessionals associated with the #StillBisexual campaign. #StillBisexual is a web-based campaign that targets myths about bisexuality and promotes bisexual identity visibility. Thematic analysis was conducted to identify emergent themes regarding the ways that individuals mark and make known their bisexuality. Three major themes of bisexual demarcation emerged including the enduring nature of bisexuality, defining bisexuality, and defining the self as a bisexual being. Discussion focuses on describing bisexual marking approaches by #StillBisexual participants and by analyzing the way bisexual demarcation challenges assumptions of monosexism and cisgenderism inherent to cultural conceptualizations of sexuality.     

Ethical Considerations for Cognitive-Behavioral Therapists in Psychotherapy Research Trials

Psychotherapy research studies, which balance the pursuit of knowledge with the provision of treatment, can place unique demands on clinicians, patients, and research staff. However, the literature on ethical considerations in psychotherapy trials is minimal. The current paper depicts CBT community standards of practice in the context of two NIMH-funded treatment trials of major depression, both involving CBT and medication. We describe issues that arose; discuss the ethical considerations involved; and describe our course of action, along with our rationale.     

Attitudes and Attributions Associated With Female and Male Partner Violence1

In an interview study, we examined attitudes toward intimate partner violence (IPV). We examined whether attitudes toward IPV varied as a function of sample (student, general, and incarcerated), participant gender, and abuse history, or as a function of perpetrator gender. Additionally, participants' conflict‐resolution strategies were examined. Findings revealed that perpetrator gender and participant abuse history were the most influential factors in shaping attitudes. Males and females evaluated violence similarly. Overall, there was greater acceptance for abuse perpetrated by females than by males, and participants who had either perpetrated or received abuse were the most condoning of IPV. A lack of conflict skills was associated with IPV. For males, this lack of skills generalized to situations outside of the relationship.     

Eating behavior in obese BED, obese non-BED, and non-obese control participants: A naturalistic study

Laboratory studies have shown considerable differences between the eating behavior, particularly binge eating behavior, of participants with and without binge eating disorder (BED). However, these findings were not replicated in two field experiments employing ecological momentary assessment (EMA) in which obese BED and obese non-BED participants reported comparable binge eating behavior. In the current study, we examined differences in binge eating with an innovative assessment scheme employing both EMA and a standardized computer-based dietary recall program to avoid some of the limitations of past laboratory and field research. Obese BED, obese non-BED, and non-obese control participants reported significant differences in eating patterns, loss of control, overeating, and binge eating behavior. Of particular importance was the finding that BED participants engaged in more overeating and more binge eating episodes than non-BED participants. These findings suggest that the use of EMA in combination with dietary recall may be a relatively objective and useful approach to assessing binge eating behavior. The findings further suggest that individuals with BED are observably different from those without the disorder, which may have implications for eating disorder diagnoses in DSM-V.     

Working memory impairment in people with Williams syndrome: Effects of delay, task and stimuli

Williams syndrome (WS) is a neurodevelopmental disorder associated with impaired visuospatial representations subserved by the dorsal stream and relatively strong object recognition abilities subserved by the ventral stream. There is conflicting evidence on whether this uneven pattern in WS extends to working memory (WM). The present studies provide a new perspective, testing WM for a single stimulus using a delayed recognition paradigm in individuals with WS and typically developing children matched for mental age (MA matches). In three experiments, participants judged whether a second stimulus ‘matched’ an initial sample, either in location or identity. We first examined memory for faces, houses and locations using a 5 s delay (Experiment 1) and a 2 s delay (Experiment 2). We then tested memory for human faces, houses, cat faces, and shoes with a 2 s delay using a new set of stimuli that were better controlled for expression, hairline and orientation (Experiment 3). With the 5 s delay (Experiment 1), the WS group was impaired overall compared to MA matches. While participants with WS tended to perform more poorly than MA matches with the 2 s delay, they also exhibited an uneven profile compared to MA matches. Face recognition was relatively preserved in WS with friendly faces (Experiment 2) but not when the faces had a neutral expression and were less natural looking (Experiment 3). Experiment 3 indicated that memory for object identity was relatively stronger than memory for location in WS. These findings reveal an overall WM impairment in WS that can be overcome under some conditions. Abnormalities in the parietal lobe/dorsal stream in WS may damage not only the representation of spatial location but may also impact WM for visual stimuli more generally.     

On the (mis)categorization of unattractive brides and attractive prostitutes: extending evaluative congruency effects to social category activation

Numerous studies have shown that social categorization is a flexible process that partly depends on contextual variables. However, little is known about the role of affect in people's access to categorical dimensions. We investigated the hypothesis that social category activation is facilitated on evaluatively congruent dimensions. Two studies provide support for this evaluative-matching hypothesis, in which social categorization was found to be faster and more accurate for evaluatively congruent categories (i.e., unattractive foreigners, unattractive prostitutes, attractive fellow-citizens and attractive brides) than for evaluatively incongruent categories (i.e., attractive foreigners, attractive prostitutes, unattractive fellow-citizens and unattractive brides). We discuss the theoretical and practical implications of these findings.     

The development of language and abstract concepts: the case of natural number

What are the origins of abstract concepts such as "seven," and what role does language play in their development? These experiments probed the natural number words and concepts of 3-year-old children who can recite number words to ten but who can comprehend only one or two. Children correctly judged that a set labeled eight retains this label if it is unchanged, that it is not also four, and that eight is more than two. In contrast, children failed to judge that a set of 8 objects is better labeled by eight than by four, that eight is more than four, that eight continues to apply to a set whose members are rearranged, or that eight ceases to apply if the set is increased by 1, doubled, or halved. The latter errors contrast with children's correct application of words for the smallest numbers. These findings suggest that children interpret number words by relating them to 2 distinct preverbal systems that capture only limited numerical information. Children construct the system of abstract, natural number concepts from these foundations.     

Contact,configural coding and the other‐race effect in face recognition

The other‐race effect (ORE) in face recognition describes a well‐established finding of better recognition for own‐race than other‐race faces. Although widely thought to reflect differences in contact between own‐ and other‐race faces, little is known about how different contact levels relate to changes in processing of those faces. This study investigated how contact affects the size of the ORE and the use of expert configural face‐coding mechanisms. Using inversion decrements as an index of configural coding, we predicted that increased self‐reported contact would be associated with greater use of configural‐coding mechanisms. Chinese and Caucasian participants varying in contact with other‐race faces were recruited. The Chinese participants also varied in their length of residence in a Western country. Results showed that higher levels of contact were associated with a reduction in the ORE in both face recognition and configural coding. Importantly, smaller cross‐race differences in configural coding were also associated with a smaller ORE in face recognition.
